ABSTRACT

Background: nonadherence is a major public health problem. It can lead to poor patient outcomes and can also complicate the interpretation of patient-centered outcomes research (PCOR), including comparative effectiveness research (CER) studies.

Objectives: The objectives of this project were to (1) develop and compare algorithms for predicting adherence to various interventions, based on data collected prior to the start of those interventions; (2) assess whether predicted adherence explains heterogeneity of treatment effects in PCOR studies; and (3) develop and compare different algorithms for predicting adherence during treatment.

Methods: To predict adherence to a newly started drug treatment, we used large health care databases to compare many different approaches to measuring patients’ prior medication adherence. We assessed whether models developed among patients starting one type of drug (eg, statins) are transportable to cohorts of patients starting other (eg, , antihypertensives) and examined the feasibility of a unified adherence prediction score. In 4 CER studies conducted in electronic health care databases (high- vs low-intensity statins on inpatient mortality and cardiovascular events; and 3 comparisons of osteoporosis medications on fracture: bisphosphonates vs calcitonin, bisphosphonates vs raloxifene, and calcitonin vs raloxifene), we stratified patients into tertiles based on their adherence prediction score and evaluated heterogeneity of treatment effects across tertiles. Finally, we examined whether the addition of posttreatment initiation information improves ability to predict whether patients will receive subsequent medication dispensation.

Results: To measure prior adherence, we identified 89 490 eligible patients who initiated a statin and had at least one previous medication dispensation. Median baseline adherence was 58%, and the 25th and 75th percentiles were 25% and 90%, respectively. Measures of prior adherence were strongly predictive of adherence to the newly started statin and improved the discriminative ability of a model containing usual adherence predictors from a C statistic of 0.665 (95% CI, 0.665-0.670) to 0.696 (95% CI, 0.691-0.701). This model did not perform as well in other drug cohorts (C-statistic in bisphosphonate initiators, 0.638 and C statistic in antihypertensive initiators, 0.654), but discrimination was improved via reestimating model parameters (0.665 and 0.672, respectively). A unified model containing a common set of predictors performed relatively well (0.684; 95% CI, 0.682-0.686). In the high- vs low-intensity statin comparison, we found some indication vs that stratification by predicted adherence score may be useful for explaining heterogeneity of treatment effects for the outcome of mortality (ie, incidence rate differences of –1.90, –2.59, and –4.43 per 1000 person-years in tertiles 1, 2, and 3 of predicted adherence, respectively), but not in the other outcomes we examined or in any of the 3 osteoporosis medication comparisons. As compared with models containing only baseline information, individual variables assessed after statin initiation provided little additional discriminative ability in predicting treatment discontinuation.

Conclusions: Incorporating measures of prior adherence can improve claims-based adherence prediction models, but the overall ability of claims data to discriminate who will and will not adhere to a new medication remains modest. While future activities involving adherence prediction should consider measures of prior adherence, we found little evidence that claims- based adherence scores can explain heterogeneity of treatment effects in CER studies and little evidence that incorporating post-initiation data meaningfully improves prediction of treatment discontinuation.

Limitations: Many potential predictors of medication adherence may not be available in administrative health care data. The modest discriminative ability of the adherence prediction scores might have precluded our ability to observe differences in treatments across strata of predicted adherence. It is also possible that there are no or only very small true differences in effects between compared treatments in the populations studied, which would have precluded us from observing differences in treatment effects across strata.

BACKGROUND

Medication nonadherence is a major public health problem.1 Less than half of patients persist with cardiovascular drugs for a year following heart attack,2 despite compelling evidence of clinical benefits of these life-saving treatments.3 Poor adherence has substantial clinical and economic consequences.4 In the United States, suboptimal adherence accounts for between 33% and 69% of medication-related hospital admissions and US$100 billion of potentially avoidable health care spending each year.1

Various effective medication adherence interventions exist.5-7 Even small improvements in adherence to evidence-based treatment can improve clinical outcomes.8,9 A key challenge in maximizing the benefit and value of these interventions is identifying populations of patients that are expected to have low adherence at the time of treatment initiation, as these patients may stand to benefit the most from adherence interventions.

In addition to contributing to poor clinical and economic outcomes for patients, medication nonadherence also complicates the interpretation of patient-centered outcomes research (PCOR), including comparative effectiveness research (CER) studies. Many randomized clinical studies use a pretrial run-in phase to exclude patients who do not adhere to the intervention(s) under study.10 However, no analogue to the run-in period exists for identifying patients who may not adhere to medications in clinical practice settings or in observational PCOR studies. As a result, patients enrolled in trials tend to adhere better than do patients who use the treatments outside of the clinical trials and in “real-world” care settings, which may be a driver of apparent discrepancies between the effects of treatments observed in observational studies vs randomized trials. Moreover, it is unclear to what extent observational study results apply to patients who adhere more or less than the “average” patient in the study population.

In this project, we sought to develop, validate, and assess adherence prediction scores, based on electronic health care data. An adherence prediction score would enable researchers to stratify study results by predicted adherence (rather than by observed adherence, which can induce bias in CER studies); identify which patients are most likely to adhere to a given

7

treatment; and potentially even quantify differences between randomized trial results and observational study results that are likely due to adherence. We focused on whether stratifying by predicted treatment adherence explains heterogeneity of treatment effects in CER studies. CER studies generally report only average results across all patients, regardless of their likelihood to adhere. We hypothesized that incorporating an adherence prediction score into CER studies would enable researchers to determine whether certain treatments work better than others for patients with different levels of predicted adherence.

In addition to developing an adherence prediction score that can predict whether patients will adhere to a newly initiated treatment, we also explored innovative adaptations of adherence prediction scores that incorporate information collected during treatment, to predict whether and when patients will stop adhering to the treatment. The specific aims of this project are outlined below.

Aim 1: Develop and Compare Algorithms for Predicting Adherence to Various Interventions, Based on Data Collected Prior to the Start of Those Interventions Many attempts have been made to predict medication adherence using routinely collected health care data.11-16 Although previously developed medication adherence algorithms have had limited predictive performance, preliminary evidence suggests that using measures of prior adherence to other chronically used medications may be a strong predictor of future adherence to a newly initiated medication.17,18 However, it is not known how best to measure and use prior medication adherence to predict adherence to a new drug. No prior study has systematically compared alternative approaches for defining prior medication adherence to optimize prediction, and no study has developed and tested prediction scores that can be applied across a wide range of drugs, patient populations, and clinical conditions. The first aim was to determine the best approaches for defining and including prior adherence in adherence prediction algorithms and to determine if a single unified prediction score applies across different patient populations and drug classes or if more specific algorithms are needed for different types of drugs.

8

Aim 2: Assess Whether Predicted Adherence Explains Heterogeneity of Treatment Effects in PCOR Studies In addition to identifying patients at the time of treatment initiation who may benefit from adherence improvement interventions, we hypothesized that adherence prediction scores may also be useful for explaining heterogeneity in CER studies. In this aim, we assessed whether stratifying by predicted adherence yielded evidence of heterogeneity of treatment effects in 3 CER use cases. We hypothesized that treatment effects would be greatest among patients with high predicted adherence and smallest among patients with lowest predicted adherence.

Aim 3: Develop and Compare Different Algorithms for Predicting Adherence During Treatment In addition to predicting whether patients will adhere to their medication, using information available at the time of treatment initiation, an algorithm to identify when patients might discontinue their medication would also help target adherence intervention strategies. During treatment, many changing factors can affect whether a patient will continue to adhere or persist. In this aim, we examined the use of post-initiation information to develop a dynamic adherence prediction score for predicting treatment discontinuation.

PARTICIPATION OF PATIENTS IN THE DESIGN AND CONDUCT OF RESEARCH

A 10-person patient advisory board (PAB) provided input into key aspects of project design and conduct and reviewed study results. The PAB comprised patients with some prior experience or education in health care who could offer meaningful input on this methods project. PAB members were recruited from Consumer Reports’ advocacy members, a group of ~7,000 educated consumers who have expressed interest in reviewing and participating in health care and consumer advocacy efforts. Consumer Reports’ advocacy members were recruited if they indicated interest in discussing issues that might be important to themselves or other patients and had some familiarity with the conduct of clinical research. The PAB gave important input into (1) patient factors that may be potential determinants or predictors of medication adherence; and (2) the design and evaluation of the aim 2 CER studies, including outcomes of interest. For the latter, PAB members reviewed and gave feedback on key decision points in the design and conduct of the aim 2 studies, such as whether each aim 2 outcome was relevant to patients. The PAB also provided insights into additional patient factors that might affect patient adherence but that are not well measured in administrative claims data, such as patients’ social support systems and the use of pill boxes, reminders, and other adherence improvement tools.

METHODS

As the 3 aims are distinct but aims 2 and 3 build directly upon aim 1, we first describe the data used in all aims and the role of the PAB and then describe the approaches used for each aim separately and in turn.

The Brigham and Women’s Hospital Institutional Review Board approved this study. Data Source All 3 aims used deidentified data from the Optum Clinformatics Data Mart. The database comprises a large, geographically and clinically diverse population of health insurance beneficiaries enrolled in commercial UnitedHealth Group–affiliated health plans as well as patients with a Medicare supplement plan. Approximately 10% of patients in the database are Medicare beneficiaries. Overall, the database includes information relating to approximately 14 million patients on a yearly basis and 60 million patients in total. The data include medical claims from health care providers and facilities, outpatient pharmacy dispensation records, and enrollment information that provides demographic data and dates of insurance eligibility for persons in the database.

Aim 1: Develop and Compare Algorithms for Predicting Adherence to Various Interventions, Based on Data Collected Prior to the Start of Those Interventions Aim 1 involved 3 main parts: (1) developing a statin adherence prediction algorithm enriched with measures of prior adherence patterns; (2) assessing the transportability of the statin adherence prediction algorithm to other drug cohorts; and (3) identifying and evaluating a single, unified adherence prediction model for application across different drug classes (Figure 1).

11

Figure 1. Overview of aim 1

Focusing initially on statins, a class of cholesterol-lowering drugs and one of the most frequently prescribed drug classes in the United States, part I sought to systematically evaluate different metrics and chronic medication classes for measuring prior adherence and, using administrative claims data, to assess the added value of these measures of prior adherence for predicting future medication adherence. In part II, we used the top-performing prediction algorithm developed in part I and applied it to cohorts of patients initiating bisphosphonates and -converting inhibitors or angiotensin II receptor blockers (ACEIs/ARBs). This enabled us to evaluate the transportability of the model for predicting adherence to different drugs and different populations from part I. We also compared the performance of the model fit in these groups with the performance of cohort-specific models developed and validated specifically to predict adherence to bisphosphonates and ACEI/ARB in these groups. Finally, in part III of aim 1 and based on the learnings from parts I and II, we developed and examined the performance of a unified prediction model that would more broadly apply across different drug classes and patient populations.

12

Aim 1, Part I: Developing a Statin Adherence Prediction Algorithm Enriched With Measures of Prior Adherence Patterns

Study cohort. We identified patients aged 18 years or older who initiated a statin between July 1, 2010, and December 31, 2011. Initiation of a statin was defined as a new statin dispensation following a 365-day baseline period in which patients were required to have continuous enrollment in the health plan and no statin dispensation. The day of the first statin dispensation was defined as the cohort entry date. For patients with multiple eligible cohort entries, only the first was included. The primary analysis focused on patients who were continuously enrolled in the plan for at least 365 days following statin initiation and who had at least one dispensation for a medication used for measuring prior adherence in the 365-day baseline period (Figure 2).

Figure 2. Aim 1, part I: Study design

Study outcomes. The outcome of interest was adherence to statins in the 365 days following the first dispensation. We measured adherence using proportion of days covered (PDC), defined as19:

= × 100 365.25 ∑ 𝑑𝑑𝑑𝑑𝑑𝑑𝑑𝑑 𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 𝑜𝑜𝑜𝑜 𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠𝑠 𝑃𝑃𝑃𝑃𝑃𝑃 � � PDC was then dichotomized using a threshold of ≥ 80%, indicating “full adherence.”20

Predictors of adherence. We measured many potential adherence predictors that are often included in claims-based studies of medication adherence. Demographic variables

13

included age and sex at cohort entry. We used claims with service dates occurring during each patient’s 365-day baseline period to define an extensive list of comorbidities, medication use, and health services use measures (eg, number of physician visits, hospitalized days, use of colonoscopy, mammography, and vaccinations; see Appendix 1 for a full list of covariates). We assessed measures of patients’ medication burden by counting the number of dispensations of all drugs and the number of unique drug types dispensed during the baseline period; evidence for medication refill synchronization, which indicates patients filling multiple prescriptions on the same day; and the number of concurrently used medications on the cohort entry date.21 We also assessed proxies of patients’ medication cost burden, including plan benefit type, total copayment for all drugs during the baseline period, and index statin copayment. These variables formed the set of basic potential predictors.

Medications for prior adherence measurement. We measured patients’ adherence to the following types of medications, using dispensations in the 365-day baseline period: ACEI/ARB, inhibitors, beta-blockers, calcium channel blockers, thiazide , loop diuretics, potassium-sparing diuretics, other antihypertensives, oral , digoxin, agents, serotonin reuptake inhibitors, typical , atypical antipsychotics, lipid-lowering agents (other than statins), antidiabetics, osteoporosis drugs, thyroid hormone, nonbiologic disease-modifying antirheumatic drugs, antiparkinson agents, , and antiglaucoma agents. We included a broad range of medications for balance, including as many patients as possible in the analysis cohort, while focusing on drugs intended to treat chronic conditions.

Prior adherence. Measurement. We assessed prior adherence using 7 different measures of prescription coverage, drug discontinuation, and dispensation counts (see Table 1 for measure definitions).

Measurement was performed over the 365-day baseline period prior to statin initiation. Measurement for each drug began at the first observed dispensation of the particular drug or in the baseline period and ended on the statin initiation date. Prescriptions filled

15

before the start of the baseline period, but with days’ supply that elapse the start of the baseline period, were not considered. Medications that were first dispensed in the 90 days immediately preceding statin initiation were excluded to ensure at least a 90-day assessment period for each drug or drug class. Switching between medications within the same pharmacologic class was allowed. For patients with multiple medications used for prior adherence measurement, we summarized across drugs by taking the mean, median, maximum, and minimum for each adherence metric.

Statistical analysis. We divided the overall statin cohort into a 50% training cohort and a 50% testing cohort. We first selected potential predictors of future statin PDC in the training cohort from among the list of covariates other than measures of prior adherence, using the least absolute shrinkage and selection operator (lasso). We fit lasso logistic regression models with a binary outcome of good adherence defined as PDC ≥ 80%, with a shrinkage parameter lambda chosen to minimize the models’ Bayesian information criterion. We selected variables with nonzero beta coefficients as predictors for subsequent models.

We then developed multivariable logistic regression models predicting PDC ≥ 80% in the training cohort by including various groups of the lasso-selected variables. For example, we built a model that included only demographic characteristics and another model that included only comorbidities. We then built a model that included all variables selected by lasso from the set of basic predictors. We also built separate univariable logistic regression models in which each of the prior medication measures was included as the only explanatory variable. We then developed models that included all the variables selected by lasso from the basic set of predictors plus the best-performing measures of prior adherence. Finally, we developed a separate model using only data available at the pharmacy at the time of prescription dispensation (ie, demographics, baseline medication use, index statin type, medication burden, and prior medication adherence) to examine the performance of adherence prediction if medical data were not available.

Each model created in the training cohort was applied to the testing cohort to predict each patient’s probability of having a 1-year PDC ≥ 80% for the newly initiated statin. The

16

predicted probabilities were used to calculate C statistics to compare discrimination across models. The C statistic (also known as the concordance statistic) is a measure of discrimination that can be interpreted as the probability that a randomly selected patient with high adherence (ie, PDC ≥ 80%) has a higher predicted probability of adherence than a randomly selected patient with low adherence. We assessed the calibration of the models using calibration plots. The model with the best performance was used in aim 1, parts II and III, and in aims 2 and 3.

To assess the strength of association between prior adherence and subsequent statin adherence, we fit a modified Poisson regression model using sandwich variance estimators,22 with a binary-dependent variable of high adherence (PDC ≥ 80%). We categorized patients into 3 prior adherence groups based on their mean PDC during the baseline period: high prior adherence (mean PDC ≥ 80%), moderate prior adherence (25% ≤ mean PDC < 80%), and low prior adherence (mean PDC < 25%). We compared the probability of having high adherence to statins across prior adherence groups, adjusting for all previously selected potential predictors from lasso regression.

Aim 1, Part II: Assessing the Transportability of the Statin Adherence Prediction Algorithm to Other Drug Cohorts

Bisphosphonate cohort. Based on the same sampling scheme applied to identify the cohort of statin initiators in part I, we identified a cohort of patients who initiated an oral bisphosphonate between January 1, 2006, and December 31, 2013. Initiation was defined as a first dispensation of an oral bisphosphonate (alendronate, risedronate, or ibandronate) with no prior dispensation of any oral bisphosphonates during a 365-day baseline period in which patients were required to have continuous enrollment in the health plan. We applied the same eligibility criteria as above to identify bisphosphonate initiators—with the additional requirements of having no diagnosis for Paget’s disease (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 731.0) and no claims for parenteral administration of osteoclast inhibitors during the baseline period.

17

ACEI or ARB cohort. Similarly, we identified a cohort of ACEI/ARB initiators from January 1, 2013, to December 31, 2013. Initiation was defined as a first dispensation of an ACEI or ARB with no prior dispensation of any ACEI or ARB during the baseline.

Study outcomes. We used the same PDC outcome from part I in part II.

Predictors of adherence. In addition to the predictors included in part I, we assessed other factors that may be associated with bisphosphonate adherence, including prior fracture, use, and bone density (BMD) tests. For the ACE/ARB cohort, we also included additional variables related to the severity of and cardiovascular comorbidities .

Statistical analysis. To assess the transportability (ie, external validation) of a model developed in statin initiators to other drug classes and populations, we compared its performance in the cohorts of bisphosphonate initiators and ACEI/ARB initiators with the performance of models developed specifically in these cohorts. To facilitate comparisons across the 3 cohorts, we first refit the part I model in the statin cohort using a 10-fold cross-validation process (in contrast to the split-sample approach used in part I). We used the C statistic to evaluate the model’s discriminative ability. We estimated the calibration slope by regressing the observed adherence outcome on the predicted probability from the prediction model: logit (full adherence) = a + b1 logit (predicted probability of full adherence); the estimated b1 represents the calibration slope. A model with a perfect calibration will have a calibration slope of 1.23 We then refit the model in the bisphosphonate and ACEI/ARB cohorts by reestimating the coefficients for each potential predictor and augmented these models by adding the cohort-specific variables described previously. Measures of performance (ie, C statistics and calibration slope) were averaged over the 10 values estimated during cross-validation for each model.

We examined the distribution of baseline potential predictors across the cohorts of statin, bisphosphonate, and ACEI/ARB initiators. We also assessed the association between

18

each potential predictor and the outcome across the 3 cohorts by comparing regression coefficients of the predictors estimated in each cohort. To further understand the importance of each variable in predicting adherence to different drug classes, we used lasso and performed 10-fold cross-validation to determine the frequency of selection of each variable across the 10 cross-validation steps. The frequency of variables selected for each fold was reported as a percentage. We also used a generalized boosted model (GBM) to assess the influence of each variable in predicting adherence across the drug classes. For each variable, the GBM computes the “relative influence,” which estimates the proportion of the model prediction ability due to each variable.24,25 The sum of the relative influence of each variable adds to 100, with higher numbers indicating a stronger contribution to predicting the response. The initial specifications of the GBM were 10 000 iterations, a learning rate parameter of 0.01, and an interaction depth of 1 for the additive approximations.

Aim 1, Part III: Identifying and Evaluating a Single, Unified Adherence Prediction Model for Application Across Different Drug Classes The purpose of part III of aim 1 was to develop a single, uniform prediction score to predict adherence across different drug classes and populations and to compare its performance with the cohort-specific adherence prediction scores.

Study cohort. For part III, we pooled the statin, bisphosphonate, and ACEI/ARB initiator cohorts developed in parts I and II to form a single larger cohort of patients initiating different medications to which we sought to predict adherence.

Predictors of adherence. The candidate set of potential predictors for the unified adherence score included those selected with high frequency during the 10-fold cross- validation performed in part II. Among the basic set of potential predictors and the measures of prior adherence assessed in each study cohort in parts I and II, we identified the variables that were selected in at least 50% of the lasso models from the cross-validation folds. Categorical variables with more than 2 levels were included if at least 1 level was selected in ≥ 50% of the lasso models.

19

Statistical analysis. We considered 2 approaches for modeling the unified adherence prediction score in the pooled cohort. First, we fit a fixed-effects logistic regression model to estimate the probability of full adherence with the variables selected as described previously. This model ignores variability in adherence to the drugs or classes being initiated and evaluated for the adherence outcome. The second model included drug class–specific random intercepts. Including random intercepts permits variation in the baseline probability of the outcome by allowing the logit of the outcome probabilities to vary across the drug classes.26 We assessed and compared the performance of these models with each other and with the cohort-specific models using C statistics and calibration plots.

Aim 2: Assess Whether Predicted Adherence Explains Heterogeneity of Treatment Effects in PCOR Studies In aim 2, we used the cohort-specific adherence prediction scores developed in aim 1 in 4 CER use cases in 2 clinical contexts. In particular, we designed and conducted CER studies comparing major cardiovascular events between patients who received low-intensity vs high- intensity statins and comparing fracture events in patients who received bisphosphonates, calcitonin, or raloxifene. We used the adherence prediction scores to estimate predicted adherence to the study drugs, to stratify patients into groups based on this predicted adherence, and to compare the outcomes between treatment groups within each stratum, in accordance with the “descriptive heterogeneity of treatment effects analysis” and the “confirmatory heterogeneity of treatment effects analysis” approaches described in the PCORI Methodology Report (Heterogeneity of Treatment Effect Standard 7.3.1). We hypothesized that the observed treatment effects would increase across strata of increasing predicted adherence score (Heterogeneity of Treatment Effect Standards 7.3.2 and 7.3.4). To determine the interaction between the treatment effect and the adherence prediction score, we tested this hypothesis using statistical modeling.

Study Design For each of the 3 CER use cases, we used a new-user, parallel group, propensity score– matched cohort study design. We identified new users of the drugs of interest (high-intensity

20

statins vs low-intensity statins; bisphosphonates vs calcitonin; bisphosphonates vs raloxifene; and calcitonin vs raloxifene). For each use case, new use was defined as having a prescription dispensation (the date of which was defined as the date of cohort entry) for either the drug of interest or the comparator following a period of at least 1 year with continuous health plan enrollment and no use of either drug or drug class. The eligible cohorts were defined using information available at the time of treatment initiation (ie, the date of cohort entry; PCORI Methodology Report Causal Inference Standard 7.2.1). All covariates (described below) were measured during the 1-year baseline period preceding the cohort entry date (Causal Inference Standard 7.2.4). We also used the 1-year baseline period to estimate each patient’s predicted adherence using the adherence prediction scores developed in aim 1.

Study Cohorts and Exposures

High-intensity vs low-intensity statins on major cardiovascular events. We identified all eligible episodes of new use of a high-intensity or low-intensity statin between January 1, 2004, and September 30, 2015. High-intensity statins included high- statins used at high doses (ie, atorvastatin > 10 mg, lovastatin > 40 mg, rosuvastatin > 5 mg, simvastatin > 40 mg) as well as any statin used at any dose in combination with ezetimibe. Statins in the high-intensity group were those that would be expected to lower low-density lipoprotein cholesterol (LDL-C) by 40% or more.27 To identify new users, we excluded episodes with any prescription dispensations for statins or ezetimibe within the year prior to the potential date of cohort entry, requiring and required continuous health plan enrollment during this baseline year. For patients with multiple eligible new-user episodes, only the first episode was included and the cohort entry date was defined as the dispensation date of the first prescription in the episode. We excluded patients with more than one prescription for a statin or a statin-containing product on the cohort entry date and those younger than 18 years on the cohort entry date.

cases, we identified all eligible episodes of new use of these drugs between January 1, 2004, and September 30, 2015. To define new use, we excluded episodes with any prior prescription dispensations for bisphosphonates, calcitonin, or raloxifene within the year prior to the potential cohort entry date and required continuous health plan enrollment during this baseline year. We excluded episodes with a prescription dispensation of more than one drug of interest on the potential cohort entry date as well those in which the patient was younger than 18 years on the cohort entry date. To focus on patients using these drugs for osteoporosis, we excluded patients with Paget’s disease, defined as ICD-9-CM code 731.0, in the 365 days before the cohort entry date as well as those with treatment with any of the following in the 365 days before the cohort entry date: risedronate 30 mg if quantity dispensed was more than 12 tablets, alendronate 40 mg if quantity dispensed was more than 12 tablets, and calcitonin injection (nonspray forms). For patients with multiple eligible new-user episodes, only the first episode was included and the cohort entry date was defined as the dispensation date of the first prescription in the episode.

Outcomes and Follow-up In accordance with Causal Inference Standard 7.2.3, we identified all outcomes following the start of exposure.

High-intensity vs low-intensity statins on major cardiovascular events. In the statin-use case, the outcomes of interest were hospitalization for cerebrovascular event or myocardial infarction (MI),28 as well as in-hospital mortality.

Bisphosphonates vs calcitonin vs raloxifene on fracture events. For the osteoporosis drug–use cases, outcomes of interest were hospitalization for fracture of the hip, humerus, pelvis, or wrist, as fractures at these 4 sites are typically considered fragility fractures.29

In both use cases, outcomes were assessed over a 1-year period, starting the day after each patient’s cohort entry date. Patients were permitted to have more than one outcome of

22

interest but no more than one of each (ie, we considered only the first event for each outcome). To achieve high specificity, all outcomes were defined based on hospitalizations and using validated algorithms that have been shown to have high performance in claims data.

The primary analysis used an intention-to-treat (ITT) model for follow-up. Follow-up began on the day after the cohort entry date and ended at the first occurrence of one of the following events: outcome occurrence, inpatient death, health plan disenrollment, end of available data, or 365 days from the cohort entry date. In an “as-treated” sensitivity analysis, patient follow-up was further censored at the time of index therapy change (eg, switching from low-dose to high-dose statin, switching from bisphosphonate to calcitonin) or discontinuation of index therapy.

Covariates Covariates included all variables needed for the respective adherence prediction scores as well as other predefined variables that are known or suspected risk factors for the outcomes of interest. These included demographics, measures of health services use and preventive care, the combined comorbidity score,30 clinical comorbidities, and use of other medications. For all 3 use cases, we assessed covariates based on enrollment information and claims during the 1 year prior to (and including) each eligible patient’s new-user cohort entry date. Age, sex, and state/region were measured on the cohort entry date only. Unless specified otherwise, covariates were identified based on one inpatient or one outpatient diagnosis in any position.

Stratifying by adherence prediction scores. We estimated each patient’s predicted adherence using the adherence prediction scores developed in aim 1—that is, we determined each patient’s values for the variables in the adherence prediction score and multiplied these values by the corresponding coefficients from the prediction models. We then summed these products to estimate each patient’s log predicted adherence.

We stratified the cohorts of eligible new users in each use case into tertiles, based on patients’ estimated predicted adherence scores. We estimated the association between the drug of interest vs comparator and each outcome of interest separately within each stratum of

23

predicted adherence and used statistical modeling to determine the interaction between the treatment effect and the adherence prediction score. Because not all patients used medications that assessed adherence before cohort entry, some patients had missing prior adherence values. The primary analysis included only patients with prior adherence values. We also conducted a sensitivity analysis in which we imputed missing values. Because results were similar to those of the main analyses, only the main analyses are presented.

Achieving balance in patient covariates. We used propensity scores to reduce confounding by balancing measured baseline covariates between the new users of the drugs of interest and comparison groups.31 All covariates described previously were included in logistic regression models to predict patients’ probabilities (ie, propensity scores) of being in the drug of interest group vs the comparison group. Because including only the adherence prediction score in the propensity score models would achieve balance on predicted adherence but not necessarily on all variables in the adherence prediction scores, we included all covariates that went into adherence score calculation in the propensity score model as well as the mean baseline PDC.

For the high-intensity statin vs low-intensity statin comparison, we matched patients by propensity score in a 1:1 ratio within a caliper of 0.01 on the probability scale using a nearest- neighbor matching algorithm. For the osteoporosis use cases, we used fine stratification on the propensity score to achieve covariate balance, because the relative sizes of the raloxifene and calcitonin groups were small compared with those of the bisphosphonate groups. Propensity score fine stratification has been found to have superior performance to 1:1 matching in this setting of disproportionate group sizes.32

Covariate balance between the treatment groups was assessed within each tertile as well as in each of the full cohorts.

Statistical Analysis We report number of events, person-time, and incidence rates for each outcome, stratified by tertile of predicted adherence and treatment group. We used incidence-rate

24

differences and Cox proportional hazards regression models to compare rates of each outcome between treatment groups. Hazard ratios and 95% CIs were estimated overall for each use case as well as within each tertile. We used the Schoenfeld test to assess for violations of proportional hazards. We tested for differences in treatment effects by predicted adherence using an interaction term between the treatment effect and the adherence prediction score. All analyses were performed using SAS statistical software, version 9.3 (SAS Institute, Inc, Cary, North Carolina).

Aim 3: Develop and Compare Different Algorithms for Predicting Adherence During Treatment Aim 3 built on aim 1 by incorporating post-initiation information into the adherence prediction model to predict, at each prescription dispensation, the likelihood that a patient would subsequently refill the prescription. We focused on a cohort of statin initiators.

Study Cohort We identified patients aged 18 years or older who initiated a statin between January 1, 2010, and September 30, 2014. Statin new use was defined the same way as in aim 1. We further restricted the cohort to patients with at least one dispensation for a medication used for measuring prior adherence in the 365 days before the cohort entry date, as in the main analysis in aim 1.

Outcomes and Follow-up The outcome of interest was statin discontinuation, which we defined as a lack of subsequent statin dispensations within 14 days following the end of a previous dispensation (ie, after the days’ supply of the previous dispensation ran out). Specifically, at each observed statin dispensation, we sought to predict the likelihood that that would be the last statin prescription that the patient would fill. For example, at the initial statin prescription, there could be 1 of 3 possible outcomes: (1) the patient filled the prescription again within the 14-day grace period, which we defined as not discontinuing provided that the date of the second dispensation occurred before a competing event (defined below); (2) the patient had no refill or competing

25

event within 14 days after the end of the first statin dispensation, which we defined as discontinuation; or (3) the patient was censored due to a competing event that precluded us from observing whether the patient received the second dispensation. At each observed prescription, we repeated the same steps and created longitudinal diaries to determine whether patients experienced discontinuation following the first through up to the 11th statin dispensation.

We followed patients from cohort entry to the earliest statin treatment discontinuation or occurrence of any competing risk event, including change in statin treatment, death, disenrollment from the health plan, end of the study period (September 30, 2015), 365 days from cohort entry, or date of dispensation of the 12th statin prescription. Statin treatment change (switch or addition) was defined as a dispensation of any other lipid-lowering agent (see Appendix Table 1 for a list of statins and other lipid-lowering agents).

Covariates We assessed the same baseline covariates as in the aim 1 statin cohort, including age at cohort entry, sex, information on index statins (specific statin and days’ supply for index statins), proxies of patients’ medical cost burden (copayment for index statins, benefit plan type, and total copayment for any drugs within 365 days preceding the cohort entry date), resource use, comorbidities, and other medication use within 365 days preceding the cohort entry date. We also estimated measures of prior medication adherence as described in aim 1.

We also assessed statin-specific covariates at each dispensation during follow-up, including specific statin as well as the days’ supply and copayment of the statin prescription. In addition, we measured covariates occurring between the current statin dispensation and the previous statin dispensation. These included all-cause hospitalization and use of 13 specific classes of cardiovascular medications (ACEIs, ARBs, renin inhibitors, beta-blockers, calcium channel blockers, thiazide diuretics, loop diuretics, potassium-sparing diuretics, other antihypertensives, oral anticoagulants, heparin and low-molecular-weight heparin, antiplatelets, and antianginal agents).

26

We hypothesized that if patients came back to fill their prescriptions before the end of the days’ supply, they would be more likely to adhere to their statin treatment. Therefore, we estimated several measures of adherence to statins up until each prescription dispensation of interest. These included the lag time for filling each prescription, which was calculated as the date of current statin dispensation minus the end date of the previous statin dispensation. The value of the lag time ranged from 1 (days’ supply of the current prescriptions) to 14. We also counted the number of chronically used medication classes that a patient discontinued in the interval between the date of current statin dispensation and the date of previous statin dispensation.

Statistical Analyses We report the number and proportion of patients who did and did not discontinue statin treatment at each of the 11 dispensations during follow-up. We also tabulated patient characteristics, adherence to other chronically used medications, and adherence measures for statins at baseline prior to cohort entry and during each interval between observed statin dispensations.

To examine whether information at or prior to statin initiation can predict whether patients will receive a second statin dispensation, we first randomly divided the eligible cohort into a training cohort and a testing cohort of equal size. In the training cohort, we fit separate logistic regression models with discontinuation (ie, lack of a second statin dispensation) as the dependent variable and each domain of baseline patient characteristics and prior adherence measures as independent variables. We also fit models that included both baseline patient characteristics and prior adherence measures as independent variables, which served as a final baseline model, as in aim 1. Each model created in the training cohort was applied to the testing cohort to predict each patient’s probability of experiencing continuation after the first statin dispensation. The predicted probabilities were used to calculate C statistics to compare discrimination across models.

27

To continue predicting patients’ likelihood of discontinuing statin treatment during follow-up, we created separate logistic regression models predicting discontinuation after each of the second through 11th dispensations. Each model included both baseline patient characteristics and prior adherence measures as independent variables. As patient characteristics and measures of statin adherence can change during treatment in ways that may predict whether patients are likely to stop adhering to their medication, we also included these updated variables assessed in the interval between the current dispensation and the previous dispensation. For example, to predict if patients discontinue after the second dispensation, in addition to including baseline patient characteristics and prior adherence measures in the model, we also included information related to the second statin dispensation, indications of whether patients were hospitalized, and indicators for whether patients used 13 predefined cardiovascular medications between the dates of the first and second statin dispensations. We also included the lag time between the first and second dispensations and number of maintenance medication classes that were discontinued between the first and second dispensations. We applied the same approach described previously to assess the predictive performance of the models over time.

RESULTS Aim 1, Part I: Developing a Statin Adherence Prediction Algorithm Enriched With Measures of Prior Adherence Patterns

Patient Characteristics and Prior Adherence for the Statin Cohort We identified 243 051 statin initiators between July 1, 2010, and December 31, 2011; 165 620 had complete follow-up during the 365 days after cohort entry. The primary analysis cohort comprised 89 490 eligible patients who had at least one dispensation for a medication used for prior adherence measurement (please see patient flow chart in Appendix 2). The average age of patients in the analysis cohort was 55 years, and 54% were female. The most common comorbidities were hypertension (56%), (26%), depression (15%), and cancer (13%) (Table 2). The median baseline PDC was 58%, and the 25th and 75th percentiles were 25% and 90%, respectively.

Statin Adherence Prediction Models Using the basic set of variables selected by lasso models—including variables related to medication burden (eg, number of any drug dispensations, number of concurrently used medications) as the only explanatory variables—yielded the highest C statistic for discriminating between those with and without full statin adherence in the testing cohort (0.614; 95% CI, 0.609-0.619; Table 3), followed by demographics (0.578; 95% CI, 0.573-0.584) and proxies of drug cost burden (0.575; 95% CI, 0.570-0.581). The model with only comorbidities had the lowest C statistics (0.540; 95% CI, 0.535-0.545). Combining all such baseline data components yielded a C statistic of 0.665 (95% CI, 0.659-0.670).

Among models including only prior adherence measures, the continuous coverage measures achieved the highest C statistics (Table 4; range: 0.614-0.666). Among them, PDC yielded the highest C statistic -up (C statistic for the model with max PDC: 0.666; 95% CI, 0.661- 0.671). Minimum PDC or minimum continuous measure of medication acquisition (CMA) yielded slightly lower C statistics compared with the mean, median, and maximum of the 2, which were all similar. Count measures including refill counts and lack of second fill measures achieved the poorest discrimination (C statistics: 0.533-0.575).

Combining prior adherence measures with the baseline data components increased C statistics (Table 5, models [a] through [d]), with addition of mean PDC achieving the highest C statistic (0.696; 95% CI, 0.691-0.701) and good calibration as portrayed in the calibration plot (Figure 3). Adding combinations of different prior adherence measures to the basic set of predictors selected by lasso did not result in material improvement over the model with a single prior adherence measure (Table 5, models [e] through [g]). Excluding variables defined using medical data yielded a C statistic of 0.687 (95% CI, 0.682-0.692; Table 5, model [h]).

Aim 1, Part II: Assessing Transportability of the Statin Adherence Prediction Algorithm to Other Drug Cohorts

Comparison of the Study Cohorts In addition to statin initiators identified in aim 1, part I, 67 607 bisphosphonate and 109 059 ACEI/ARB initiators were included in the part II analyses. Several patient characteristics differed across drug cohorts, including age, sex, and prior adherence patterns (Table 7). The proportions of patients classified as fully adherent (ie, PDC ≥ 80%) were similar between statin (35%) and bisphosphonate (34%) cohorts but were higher for ACEI/ARB initiators (46%).

Model Development and Performance The model developed in the statin cohort performed less well when applied to the bisphosphonate cohort, with a C statistic of 0.638 (Table 9) compared with 0.695 from the statin cohort.

The same model performed slightly better in predicting adherence to ACEI/ARBs (C statistic, 0.654), but still considerably lower than among statin initiators (Table 10).

Reestimating the coefficients in the bisphosphonate and ACEI/ARB cohorts improved the discriminative ability substantially, with C statistics from the refitted models of 0.665 and 0.672 in the bisphosphonate cohort and ACEI/ARB cohort, respectively. Adding variables specific to the clinical scenario further improved model discrimination in the bisphosphonate cohort (0.679) but made little improvement in the ACEI/ARB cohort (0.674). Transporting the statin model to the bisphosphonate and ACEI/ARB cohorts also resulted in substantial miscalibration, as evidenced by decreases in the calibration slope from 0.990 to 0.695 and 0.718 for the bisphosphonate cohort and ACEI/ARB cohort, respectively (Tables 9 and 10).

Predictor Importance To assess the relative importance of each variable in separately predicting adherence to statins, bisphosphonates, and ACEI/ARBs, we calculated the frequency that each was selected by lasso in the 10-fold cross-validation. A total of 68, 70, and 66 variables were selected in at least 50% of the cross-validations for the statin, bisphosphonate, and ACEI/ARB cohorts, respectively (Appendix 6). Frequently selected variables among the common set of predictors available for all cohorts included age, sex, region, and receipt of colonoscopy, mammography, and vaccinations. Prior mean PDC for maintenance medications dispensed during baseline was selected in 100% of the models. Selection of certain variables varied across cohorts. Some of the more frequently selected variables for the statin cohort included history of cardiovascular events, such as MI and stroke, while bisphosphonate-specific variables included rheumatoid arthritis, number of BMD tests, and baseline use of other osteoporosis medications. Appendix 6presents the frequency with which each variable was selected among the 10-fold cross- validation.

Variable influence also varied across the 3 drug cohorts in the GBMs. Prior mean PDC was the strongest predictor of outcome adherence for all 3 cohorts, though the extent of its contribution to the models varied across the cohorts (Appendix 7). Its relative influence was more than 45% in predicting adherence to statins and ACEI/ARBs and approximately 25% in the model predicting adherence to bisphosphonates. In addition to variables reflecting medication burden (eg, number of chronic medications, concurrent medications), which tended to be

46

important in predicting adherence in all 3 drug cohorts, demographic variables, such as age and region, were more important in the statin cohort; however, proxies for osteoporosis severity, such as BMD tests and use of other osteoporosis medications, contributed more in predicting adherence to bisphosphonates.

Aim 1, Part III: Identifying and Evaluating a Single, Unified Adherence Prediction Model for Application Across Different Drug Classes Keeping in mind the differences in relative importance and influence identified in part II, we sought to evaluate in part III whether a universal model with a common set of variables could predict adherence to each of the 3 drug classes of interest. The unified model included those variables in part II that were selected in at least 50% of the cross-validations. The C statistic for the universal model was 0.675 (95% CI, 0.673-0.677) for the fixed-effects model and 0.684 (0.682-0.686) for the random-effects model. These values were higher than the C statistics for the models refit to the bisphosphonate (0.665) and ACEI/ARB (0.672) cohorts in part II but lower than the C statistic from the statin model in aim 1 (0.696; 95% CI, 0.691-0.701).

The ORs relating the predictors to the adherence outcome were similar for the fixed- effects and random-effects models (Appendix 8). In the random-effects model, the estimated intercept was −2.057, and the estimated variance of the random effects was 0.054; this was significantly different from 0 (p = 0.005), indicating substantial variation in baseline risk of the outcome across the drug classes. The estimated ORs reported in Appendix 8 can be interpreted as the associations between the variables and the outcome based on within-drug-class comparisons. In addition to a higher C statistic, including the random intercept to allow the baseline probability of outcome adherence to vary by drug class also improved calibration, as evidenced by the calibration plots from the 2 models (Figure 3).

Aim 2: Assess Whether Predicted Adherence Explains Heterogeneity of Treatment Effects in PCOR Studies

High-intensity vs Low-intensity Statin Cohorts For the aim 2 statins cohort, we identified 2 090 347 eligible statin initiators who were at least 18 years of age and enrolled in a health care plan for a minimum of 12 months before treatment initiation (Appendix 9). Of them, 1 523 949 were low-intensity and 566 398 were high-intensity statin users. The prior mean (SD) PDC to other maintenance medications was 0.76 (0.26); a total of 481 479 (23%) statin initiators were excluded from the primary analysis because they did not have the PDC information.

We used the final statin adherence prediction model from aim 1 to estimate each patient’s adherence prediction score. We then stratified patients into tertiles of predicted adherence based on these scores. As expected, the prior mean PDC as well as the average PDC to statins in follow-up increased monotonically from the first to third tertile (Table 11). Prior mean (SD) PDC was 0.53 (0.26) in the first tertile, 0.84 (0.18) in the second tertile, and 0.91 (0.13) in the third tertile. Predicted adherence was similar for low- and high-intensity statin initiators within each tertile even before balancing by propensity score.

Despite increases in mean age across tertiles (56, 60, and 69 years across the first through third tertiles, respectively), patients in the second tertile tended to be the healthiest, with a mean combined comorbidity score of 0.36 (1.77) compared with 0.52 (1.92) and 0.80 (2.20) for patients in the first and third tertile, respectively (Appendices 10-13). Between treatment groups, patients had similar mean age (60 [13.4] vs 59 [13] years); however, fewer low-intensity statin initiators were female, and low-intensity initiators had lower combined comorbidity scores (0.53 [1.89] vs 0.63 [1.96]). Low-intensity statin initiators also had a lower prevalence of heart failure, acute coronary syndrome, hyperlipidemia, hypertension, and ischemic heart disease. High-intensity statin users tended to use more antiplatelets, ARBs, beta- blockers, nitrates, and other lipid-lowering drugs. Differences in covariates between treatment groups tended to increase from the first to third tertile.

Across the tertiles, 94% (n = 147 442 pairs), 95% (n = 135 118 pairs), and 91% (n = 122 870 pairs) of high-intensity statin initiators were matched by propensity score, respectively. Within each stratum, patient characteristics between treatment groups were well balanced after matching (Appendices 14-17). In the matched cohorts, the prior mean PDC for both low- intensity and high-intensity statin groups were 0.53, 0.85, and 0.91 across tertiles (Appendix 18). The follow-up statin PDC was 0.40, 0.57, and 0.63 for both groups across tertiles (Appendix 18).

High-intensity vs Low-intensity Statins on Major Cardiovascular Events Within the propensity score–matched cohorts, the incidence rates for inpatient mortality were lower for high-intensity statin initiators compared with low-intensity statin initiators in the overall data and within tertiles in both the as-treated and ITT analyses (Table 12). In the overall cohort, the as-treated incidence rate per 1000 person-years (IR per 1000py) was 19.6 (2165 events) for low-intensity and 15.6 (1643 events) for high-intensity statin initiators. IR differences increased from –1.90 in the first tertile to –2.59 in the second tertile and –4.43 in the third tertile.

The hazard ratios (HRs) for inpatient mortality were 17% (HR, 0.83; 95% CI, 0.75-0.93), 20% (HR, 0.80; 95% CI, 0.72-0.90), and 23% (HR, 0.77; 95% CI, 0.71-0.84) lower in high-intensity statins in the first, second, and third tertiles, respectively. Compared with that of low-intensity statins, the rate of inpatient mortality overall was 20% lower among high-intensity statin initiators (HR, 0.80; 95% CI, 0.76-0.85) in the as-treated analysis and 13% lower in the ITT analyses (HR, 0.80; 95% CI, 0.77-0.84). HRs in the ITT analyses were 0.86 (95% CI, 0.79-0.94), 0.83 (95% CI, 0.76-0.90), and 0.81 (95% CI, 0.76-0.86) in the first, second, and third tertile, respectively.

The incidence rates for MI and cerebrovascular event hospitalizations were similar for high-intensity and low-intensity statin initiators overall and within tertiles in both as-treated and ITT analyses (Appendices 19 and 20). Overall, the as-treated IR per 1000py for MI was 8.8 (2267 events) for low-intensity and 8.9 (2203 events) for high-intensity statin initiators. IRs per 1000py were 6.8 vs 6.5 (558 vs 556 events) in the first tertile, 6.8 vs 6.7 (564 vs 578 events) in the second tertile, and 13.4 vs 13.4 (1090 vs 1150 events) in the third tertile. Corresponding HRs comparing high- vs low-intensity statin initiators were 1.06 (95% CI, 0.92-1.21), 1.01 (95% CI, 0.89-1.16), and 1.00 (95% CI, 0.91-1.09), respectively, in as-treated analyses. HRs were 1.02 (95% CI, 0.92-1.12), 1.00 (0.91-1.11), and 0.94 (0.87-1.01), respectively, in the ITT analyses.

Overall, the as-treated IR per 1000py for cerebrovascular event hospitalizations was 12.8 (3294 events) for low-intensity and 13.3 (3285 events) for high-intensity statin initiators.

52

IRs per 1000py were 10.2 vs 10.1 (839 vs 861 events) in the first tertile, 10.9 vs 10.5 (898 vs 906 events) in the second tertile, and 18.8 vs 17.5 (1532 vs 1495 events) in the third tertile. Corresponding HRs comparing high- vs low-intensity statin initiators were 0.99 (95% CI, 0.89- 1.11), 0.98 (95% CI, 0.89-1.09), and 1.05 (95% CI, 0.97-1.14), respectively. HRs were 1.07 (95% CI, 0.98-1.16), 1.01 (0.93-1.09), and 1.08 (1.01-1.16), respectively, in the ITT analyses.

Bisphosphonates vs Calcitonin vs Raloxifene Cohorts We identified 589 788 eligible patients who were at least 18 years of age; were new users of bisphosphonates, calcitonin, or raloxifene (with no use of the index therapy or teriparatide in the prior year); and had no ICD-9-CM diagnosis code for Paget’s disease in the prior year and no fracture in the prior year. The overall cohort comprised 510 962 patients who initiated bisphosphonates, 26 851 who initiated calcitonin, and 51 975 who initiated raloxifene (Appendix 21).

The prior mean (SD) PDC for cohort members was 0.76 (0.23); 226 131 (50.4%) did not have prior PDC information. As expected, prior mean PDC and PDC for the index drug during follow-up increased monotonically across tertiles for all comparisons (Appendices 22-24).

Raloxifene initiators (62 years) were the youngest, followed by bisphosphonate initiators (65 years) and calcitonin initiators (68 years; Appendices 25-48). Before application of propensity score methods, the calcitonin group, compared with the bisphosphonate group, had a higher prevalence of several comorbid conditions, including coronary atherosclerosis (11% vs 7%), cancer, heart failure (8% vs 4%), chest pain (17% vs 13%), chronic obstructive pulmonary disease (COPD; 14% vs 6%), depression (11% vs 8%), history of falls (3% vs 1%), hypertension (40% vs 27%), and ischemic heart disease (11% vs 4%). Bisphosphonate initiators tended to have higher prevalence of comorbidities than did raloxifene initiators, including COPD (10% vs 6%), hyperlipidemia (45% vs 35%), hypertension (39% vs 27%), and renal dysfunction (6% vs 3%),

Bisphosphonates vs Calcitonin on Fracture Events After application of the propensity score fine stratification technique in the primary as- treated analyses (Table 13), the IR per 1000py for fractures in the overall cohort PDC values was 14.16 for bisphosphonates and 13.66 for calcitonin. IRs per 1000py across the first through third tertiles were 15.47, 11.38, and 15.44, respectively, for bisphosphonate initiators and 17.24, 9.58, and 13.91, respectively, for calcitonin initiators. The overall HR comparing bisphosphonate vs calcitonin initiators was 0.97 (95% CI, 0.96-1.35) in the as-treated analysis and 1.01 (95% CI, 0.83-1.24) in the ITT analysis.

Aim 3: Develop and Compare Different Algorithms for Predicting Adherence During Treatment

Patient Characteristics For aim 3, we identified 1 126 274 adult statin initiators between January 1, 2010, and September 30, 2014; 695 253 patients had at least one dispensation for a medication used for prior adherence measures and were eligible for the analysis. The mean (SD) age of the cohort was 63 (13) years, and 45% were male. Simvastatin was the most commonly used statin (36%), followed by atorvastatin (27%), and pravastatin (20%). Most patients had an ICD-9-CM diagnosis code for hyperlipidemia (80%) in the baseline period; 74% had codes for hypertension and 36% had codes for diabetes. Frequently used medications during the baseline period included ACEIs (41%), opioids (38%), beta-blockers (36%), thiazide diuretics (34%), antidiabetics (29%), and calcium channel blockers (27%). On average, patients received 25 prescriptions and 10 unique drug dispensations during the baseline period; on average, 5 unique drugs were concurrently dispensed when patients initiated statin treatment. The prior mean PDC to maintenance medications was 0.76 (Appendix 49).

Sequential Statin Dispensations During Follow-up Figure 4 depicts the number and proportion of patients who did and did not discontinue statin therapy after each prescription during follow-up. Among the 695 253 eligible patients, only 377 658 (54%) filled a second prescription; 265 160 (38%) did not fill their second prescription and 52 435 (8%) were censored, precluding us from observing whether they filled a second prescription. Less than 8% (n = 50 177 patients) filled 12 prescriptions during the follow- up period; however, among those patients who adhered to treatment at each sequential dispensation in follow-up, the proportion who continued adhering to statin treatment increased: 74% to 79% of patients filled their third through sixth prescriptions, and 83% to 88% filled their seventh through 12th prescriptions.

Among those who continued to fill prescriptions, the proportion with hospitalization for any cause decreased from 3% before filling the second prescription to 1% before filling the 12th prescription. In addition, the proportion of patients receiving specific cardiovascular medications increased slightly over time, and we observed a decreased trend in discontinuation of other maintenance medications among those who continued to adhere to their statin therapy (Table 16).

Performance of Baseline Information in Predicting Statin Discontinuation Similar to predicting full adherence in aim 1, using the baseline patient characteristics as independent variables for predicting discontinuation after the first statin dispensation, the model including medication burden showed the best performance in the validation cohort (n = 321 400) among those including only a single domain of variables (C statistic, 0.583), followed by medical cost burden (C statistic, 0.567), and information on index statins and other medications (C statistic, 0.557). The model including only demographic variables had the lowest C statistic (0.526). Combining all such data components into a single model yielded a C statistic of 0.624 (Table 17).

With respect to prior adherence measures, as in aim 1, the model including the prior mean or median PDC showed the best ability in predicting discontinuation after the initial dispensations (C statistic, 0.588), which was better than the performance of any individual baseline patient characteristics. The model including the number of medication classes that were discontinued in baseline yielded the lowest C statistic (0.532). Combining all baseline characteristics, prior mean PDC, and number of medication classes discontinued during the baseline period yielded a C statistic up to 0.645. The discriminative ability of this model, using only baseline information, decreased at each sequential dispensation during follow-up, with C statistics of 0.629 for predicting discontinuation after the second dispensation and 0.598 for predicting discontinuation after the 11th dispensation (Table 18).

Incorporating Dynamic Post-initiation Information for Predicting Statin Discontinuation Overall, in comparison with the models with only baseline information, the individual variables assessed after statin initiation provided little additional discriminative ability in predicting discontinuation after the second through 11th dispensations. Days’ supply of each statin prescription and the lag time between dispensations provided slightly better predictive performance than did other post-initiation information. Combining all baseline and follow-up variables measured up to the most recent dispensation offered modest improvement in C statistics, although the C statistics still declined over time (Table 18).

DISCUSSION Context for Study Results This project was designed to advance methods for predicting medication adherence using administrative claims data. Claims data are frequently used for CER of medications and are becoming increasingly available to clinicians at the point of service. In particular, we conducted a systematic evaluation of approaches to using measures of prior adherence to predict patients’ future adherence to a newly initiated medication, and we explored whether a universal adherence prediction score could be useful for predicting adherence to multiple drug classes. We also examined whether stratifying patients in CER studies by predicted adherence could explain apparent heterogeneity of treatment effects. Finally, we attempted to further advance adherence prediction in claims data by updating models with post-initiation information.

Aim 1: Develop and Compare Algorithms for Predicting Adherence to Various Interventions, Based on Data Collected Prior to the Start of Those Interventions Aim 1 focused on developing drug-specific as well as universal adherence prediction models for use in administrative claims data. Across 3 drug cohorts, we found that among claims-based predictors of adherence, measures of prior adherence are relatively strong predictors of future adherence and that adding measures of prior adherence to models containing usual claims-based adherence predictors modestly improved model discriminative ability; however, even the top-performing models achieved C statistics less than 0.70.

In applying a model developed specifically among statin initiators to other drug cohorts, we observed reduced model performance. This lack of calibration when transporting a prediction model from one population to another is often underappreciated.33 We found that performance could be improved by reestimating the model coefficients in the drug cohorts of interest. We also found that different variables may have different influences on adherence prediction for different drugs. Despite these variances, we did find that a model that included a

65

common set of variables that were predictors of adherence to each of the 3 drug classes performed relatively well in the pooled cohort.

Aim 2: Assess Whether Predicted Adherence Explains Heterogeneity of Treatment Effects in PCOR Studies We had hypothesized that stratifying patients in a CER study by their predicted adherence would reveal heterogeneity of treatment effects—that is, we expected to observe larger differences in treatment effects among patients who were predicted to adhere to the treatments than among patients who were less likely to adhere, as drugs work only if patients take them. As expected, we found that patients’ adherence to the study drugs in follow-up increased monotonically across strata of predicted adherence. We did find some indication in the high- vs low-intensity statin mortality comparison that such stratification might be useful for identifying patients who may be more likely to benefit from high-intensity statins, but not in the other outcomes we examined or in any of the 3 osteoporosis comparisons.

Aim 3: Develop and Compare Different Algorithms for Predicting Adherence During Treatment Aim 3 sought to build on aim 1 by assessing whether incorporating post-initiation information could further enhance claims-based medication adherence prediction algorithms. We observed several interesting findings relating to patterns of treatment discontinuation over time. For example, only about half of patients filled an initial statin prescription more than once. As one might expect, as long as patients continued receiving subsequent dispensations, their probability of continuing to adhere increased over time because those who discontinued treatment were selectively removed from further consideration. Also, as one might expect, the ability of baseline information to predict subsequent discontinuation decreased the further out from treatment initiation. We also observed a decline in C statistics over each of the 12 dispensations when variables measured in follow-up were added to the baseline variables, though this trend was not monotonic. With each sequential prescription dispensation, the population of patients who persisted with the medication decreased in size. It is possible that as the cohort dwindled, the distributions of measured variables that predict discontinuation

66

narrowed among those who remained, making it difficult to compare C statistics over time in these slightly different populations.34 Nevertheless, despite the interesting patterns that we observed, we found little incremental improvement from the addition of post-initiation information.

Uptake of Study Results Findings from aim 1 suggest that researchers or practitioners seeking to predict medication adherence using administrative claims data should incorporate measures of prior adherence to chronic medications when patients have been prescribed such treatments. Mean PDC for a wide range of maintenance medications used prior to the start of a new drug tended to perform relatively well. Findings from aim 1 also suggest that drug-specific adherence prediction models perform better than universal adherence prediction scores that are developed for one drug class and applied to another. These findings are consistent with prior research on other types of clinical prediction models.35,36 However, when it is infeasible to estimate or use a drug-specific model, a universal adherence prediction score may be useful. We expect that this finding would apply to other populations and settings as well—that is, it would be preferable to develop and validate an adherence prediction model in the specific population or setting in which it is to be applied. However, when this is not feasible, transporting a drug-specific model developed in a different population or setting, or even transporting a universal adherence prediction score, may be a viable option. Although adding measures of prior medication adherence improved the C statistics, the overall discriminative ability of the models remained low, likely owing to the limitations of claims data in capturing measures of adherence and its predictors (see Study Limitations section). The modest C statistics limit the utility of claims data for identifying patients who are likely to become nonadherent at the time of initiating a new treatment.

Results from aim 2 suggest that adopting the approach of stratifying CER studies by predicted adherence could potentially help to assess heterogeneity of treatment effects; however, this should be done with caution, as we saw patterns of results consistent with our hypothesis in only one use case.

67

Study Limitations Although measures of prior medication adherence were relatively strong predictors of future adherence, when compared with typical claims-based predictors of adherence, their inclusion resulted in models with only modest discriminative ability. As emphasized by the PAB, administrative claims data lack information on potentially important predictors of medication adherence, such as social support, adverse effects, and use of adherence interventions, such as pill boxes or other reminders, which may explain the ability to achieve only modest discrimination. Measures of prior adherence do not contribute to adherence prediction of all patients, as not all patients have had prior use of a chronic medication for assessing prior adherence. Furthermore, while claims data are accurate for identifying who has received a prescription dispensation that generated an insurance claim, they do not provide information about whether patients actually consume the medications that they receive. As such, claims- based measures of adherence, such as PDC, reflect only a proxy of patients’ true medication adherence behavior. Although prior studies have found reasonable concordance between claims-based measures of adherence and pill count (ie, when an interviewer counts the number of pills that a patient has available and compares this with the expected number had the patient taken the medication according to the prescribing instructions),37 the discrepancy between claims-based adherence and true adherence could also partly explain the modest discriminative ability that we observed.

There are at least 3 reasons that stratifying by adherence prediction did not lead to meaningful differences in treatment effects across strata for any of the osteoporosis examples in aim 2. First, it is possible that the modest discriminative ability of the claims-based adherence prediction scores precluded our ability to observe differences. For example, while the prior mean PDCs were 0.53, 0.85, and 0.91 across tertiles of adherence prediction score in the statins use case, differences in observed follow-up statin PDC were smaller at 0.40, 0.57, and 0.63, respectively. It is possible that larger differences in actual adherence are necessary to yield evidence of heterogeneity of treatment effects. Second, stratification by adherence prediction score not only sorted patients based on their predicted adherence but also resulted in groups of patients that differed in other ways across strata. In the statins use case, comorbidity burden,

68

as assessed by the combined comorbidity score, increased monotonically across tertiles of adherence prediction score. Outcome rates were similar in the first and second tertiles but were considerably larger in the third tertile. In the osteoporosis example, patients in the first tertile had the highest comorbidity burden and patients in the third tertile had the lowest burden. Those in the second tertile tended to have the lowest rates of facture, while those in the first and third tertiles had similar rates. These differences in patient characteristics and outcome event rates across strata complicate assessments of heterogeneity of treatment effects due to adherence prediction score. Finally, it is possible that there are no or only very small true differences in effects between compared treatments, especially over the relatively short 1-year duration of follow-up in these studies, which could have precluded us from observing differences in treatment effects across strata.

Furthermore, the CER studies in aim 2 are subject to potential biases common in claims- based observational studies, including unmeasured confounding and misclassification of exposures and outcomes. While the active comparator new-user design can help address both measured and unmeasured confounding, we cannot rule out differences between groups in certain potentially important confounders, such as the severity of the condition for which the drugs are prescribed.

Across all 3 aims, we focused on a limited set of drug cohorts and clinical outcomes, which may limit the generalizability of our findings.

Future Research To our knowledge, this was the first systematic evaluation of the use of prior medication adherence to predict future adherence and the first examination of whether predicted adherence can explain heterogeneity of treatment effects. Future research should assess whether our findings apply to other drugs, other clinical contexts, and other populations and settings. Future work should also consider whether complementary data sources may enrich claims-based medication adherence prediction. Recent studies suggest that electronic health record (EHR) data may add value to adherence prediction.38 Patient-reported information or data collected from mobile health applications should also be considered.

69

Although we found little evidence that incorporating post-initiation data meaningfully improves prediction of treatment discontinuation, more work is needed to predict when patients are at risk of discontinuing their medications, as this may be the optimal timing for administering adherence improvement interventions. This may be a particularly valuable setting for enriching claims data with complementary data sources, such as EHR data or patient-reported data. Recent work has found that medication adherence and life events among family members can be associated with an individual’s medication adherence.39,40 Future work should evaluate the extent to which this information can improve claims-based adherence prediction. It is possible that better adherence prediction could improve confounding adjustment in claims-based observational studies or could help inform treatment decisions at the time of prescribing if, for example, a patient is likely be more adherent to one treatment vs another.

CONCLUSIONS

Measures of prior medication adherence appear to be stronger predictors of future adherence compared with other usual claims-based predictors of adherence. Incorporating measures of prior adherence can improve claims-based adherence prediction models. Drug- specific adherence prediction models are likely to perform better than universal adherence prediction scores; however, when it is infeasible to develop and validate a drug- or cohort- specific score in a given population or setting, transporting a universal adherence prediction score may be viable. Overall, the ability of claims data to discriminate who will and will not adhere to a new medication remains modest, likely due to a lack of several important correlates of medication adherence in claims data as well as to misclassification of claims-based measures of adherence and their predictors.

Although future activities involving adherence prediction should consider the measure of prior adherence, we found little evidence that claims-based adherence scores can explain heterogeneity of treatment effects in CER studies. This is likely due, in part, to the fact that patients with different predicted adherence also differ in other important clinical characteristics, making it difficult to disentangle potential effect measure modification due to differences in adherence vs differences in other patient characteristics. We also found little evidence that incorporating post-initiation data meaningfully improves prediction of treatment discontinuation; however, this area deserves attention in future work, especially where claims data can be linked to complementary data sources.
