−This Clinical Resource gives subscribers additional insight related to the Recommendations published in− March 2019 ~ Resource #350301 Potentially Harmful Drugs in the Elderly: Beers List In 1991, Dr. Mark Beers and colleagues published a methods paper describing the development of a consensus list of medicines considered to be inappropriate for long-term care facility residents.12 The “Beers list” is now in its sixth permutation.1 It is intended for use by clinicians in outpatient as well as inpatient settings (but not hospice or palliative care) to improve the care of patients 65 years of age and older.1 It includes medications that should generally be avoided in all elderly, used with caution, or used with caution or avoided in certain elderly.1 There is also a list of potentially harmful drug-drug interactions in seniors, as well as a list of medications that may need to be avoided or have their dosage reduced based on renal function.1 This information is not comprehensive; medications and interactions were chosen for inclusion based on potential harm in relation to benefit in the elderly, and availability of alternatives with a more favorable risk/benefit ratio.1 The criteria no longer address drugs to avoid in patients with seizures or insomnia because these concerns are not unique to the elderly.1 Another notable deletion is H2 blockers as a concern in dementia; evidence of cognitive impairment is weak, and long-term PPIs pose risks.1 Glimepiride has been added as a drug to avoid. Some drugs have been added with cautions (dextromethorphan/quinidine, trimethoprim/sulfamethoxazole), and some have had cautions added (rivaroxaban, tramadol, SNRIs). Notable drug interactions added include opioids plus benzodiazepines or gabapentenoids.1 Use of the Beers list has not been convincingly shown to reduce morbidity, mortality, or cost but is often used by organizations as quality measures. Use the list to identify red flags that might require intervention or close monitoring, not the final word on medication appropriateness.2 Medication use decisions must be individualized.2 If the decision is made to stop a potentially inappropriate medication, tapering may be needed (e.g., benzodiazepines, corticosteroids, acetylcholinesterase inhibitors, PPIs).2 The chart below summarizes the 2019 Beers list, potential therapeutic alternatives, and other considerations. Drugs categories include Analgesics, Antibiotics, Anticonvulsants, Antidepressants, Antigout, Antihistamines, Antihypertensives, Antiplatelets/Anticoagulants, Antipsychotics, Anxiolytics, Cardiac Drugs, Central Nervous System Agents (misc.), Diabetes Drugs, Gastrointestinal Drugs, Hormones, Hypnotics, Musculoskeletal Agents, NSAIDs, Respiratory Drugs, Urinary Drugs, Vasodilators.

A Medicare Advantage and Part D display measure. Designated CMS high-risk meds based on 2012 Beers list.
