Predictors of Receipt of Comprehensive Medication Reviews in Older Adults.

Abstract

Polypharmacy is highly prevalent among older adults. This study's purpose was to provide nationally representative estimates of self-reported comprehensive medication review (CMR) receipt among older adults and describe factors associated with their receipt, as CMRs are available through the Medicare Part D program. This cross-sectional study used data from the National Poll on Healthy Aging (NPHA), a nationally representative online survey of community-dwelling adults aged 50-80, administered in December 2019. Participants included older adults aged 65-80 with any health insurance (n = 960). Outcomes were self-reported CMR receipt, awareness of CMR insurance coverage, and interest in a future CMR with a pharmacist. Sociodemographic and health-related variables were included. Descriptive statistics and multivariable logistic regression with NPHA population sampling weights were used. Among older adults on 2 or more prescription medications, only 20.8% had received a CMR while 34.3% were interested in a future CMR. Among individuals who had not received a CMR, most (83.4%) were unaware their insurance might cover a CMR. Factors associated with higher odds of receiving a CMR included taking 5 or more prescription medications (adjusted odds ratio [AOR] = 2.6, 95% CI: 1.59-4.38) and reporting food insecurity (AOR = 2.9, 95% CI: 1.07-7.93). Having fair or poor self-reported physical health was associated with lower odds of receiving a CMR (AOR = 0.49, 95% CI: 0.25-0.97). Most older adults on 2 or more prescription medications with health insurance had not received a CMR and many were interested in one. Targeted strategies to increase older adults' awareness and receipt of CMRs are warranted.
