The purpose of this assessment is to provide a snapshot of what is being prescribed for youth and young adults (ages 12-29) in Maryland. Using the PDMP data, this report characterizes trends in dispensing rates over time from January 2015 through June 2018. It identifies prescribing patterns of the therapeutic classes of interest among healthcare providers to identify prescription rates and trends with particular emphasis on opioids. This analysis is an essential first step in evaluating the need for further education or interventions at the prescriber-level. Interventions and education to prescribers of adolescents can decrease exposure and prevent future misuse of prescription drugs. Youth and young adults prescribing patterns are important to monitor and this is an important step in surveillance of prescription drug dispensing patterns. Early exposure to prescription opioids in adolescence is significantly associated with non- medical use of prescription opioid (NMUPO) use at age 351. The specific aims of this assessment are to review Schedule II-V prescription drug dispensing rates and patterns across therapeutic classes, and at both the state and jurisdiction level and with particular emphasis on Maryland youth (12-17 year olds) and young adults (18-24; 25-29 year olds) from January 2015 – June 2018. Additionally, the assessment will characterize the prescribing patterns of healthcare providers across therapeutic classes for youth and young adults. The most current PDMP data from Chesapeake Regional Information System for our Patients (CRISP) was used for this assessment (updated as of November 2018). Records from January 2015 through June 2018 in the state of Maryland were selected for analyses, broken up into six- month intervals. The data was analyzed at the statewide, jurisdictional and provider level for youth and young adults (ages 12-29) in Maryland. The majority of prescription fills to youth recipients (12-17) and young adults (18-24) were stimulant medications. The young adults in their late twenties (25-29) fill proportionately more opioids than their younger counterparts do. Prescription opioids fills dispensed to young adults (18-29) demonstrate the greatest decrease in fills from 2015 to mid-2018 out of all the prescription drug classes. Doctors followed by dentists prescribed the greatest amount of fills dispensed to Maryland youth and young adults. Proportionately, doctors prescribe more stimulants than any medication in the other drug categories. Among dentists, just over 90% of prescriptions prescribed for youth and young adults are opioids. There are proportion differences of drugs dispensed to youth and young adults within the jurisdictions relative to the Maryland proportion of the dispensed drug. Overall, this assessment provides a first step in data analysis to begin the discussions with other key stakeholders for developing education and interventions for providers, youth and young adults in Maryland. 2 | P a g e TABLE OF CONTENTS EXECUTIVE SUMMARY 2 LIST OF TABLES 5 LIST OF FIGURES 6 1.0 INTRODUCTION 9 1.1.
