Psychoactive medication use among older community-dwelling Americans.

backgroundFalls are a common and serious health issue among older Americans. A common fall risk factor is the use of psychoactive medications. There is limited recent information on the national prevalence of psychoactive medication use among older Americans.

objectivesTo estimate the prevalence of psychoactive medication use among community-dwelling older Americans and compare it with previous estimates from 1996.

methodsThe data source was the 2013 Cost and Use Data files combining Medicare claims data and survey data from the Medicare Current Beneficiary Survey, an in-person nationally representative survey of Medicare beneficiaries. Participants were included if they were 65 years of age and older, lived in the community, and had a complete year of prescription use data. Medication use was examined for 7 classes of psychoactive medications categorized by the 2015 American Geriatric Society Beers criteria as increasing fall risk. These include opioids, benzodiazepines, selective serotonin reuptake inhibitors, anticonvulsants, nonbenzodiazepine sedative hypnotics, antipsychotics, and tricyclic antidepressants. Data on participant demographic factors were also collected.

resultsAmong the 6959 community-dwelling older adults studied, representing 33,268,104 community-dwelling Medicare beneficiaries, 53.3% used at least 1 psychoactive medication linked to falls in 2013. The most frequently used medication classes were opioids (34.9%), benzodiazepines (15.4%), selective serotonin reuptake inhibitors (14.3%), and anticonvulsants (13.3%). These estimates are considerably higher for all classes except tricyclic antidepressants than previous reports from 1996 that used the same data source. Among most psychoactive medication classes observed, women had higher usage than men.

conclusionMore than half of all older Americans used at least 1 psychoactive medication in 2013. Health care providers, including pharmacists, play a vital role in managing older adults' exposure to psychoactive medications. Medication management can optimize health and reduce older adult falls.
