Objectives: To describe the effect of age on psychotropic coprescribing, psychiatric diagnoses, and other clinical characteristics.
Design: Analysis of the National Ambulatory Medical Care Survey.
Setting: A national sample of outpatient visits to physicians (N = 2,406) in office-based practice in 2010.
Participants: Adults prescribed psychotropic medication (N = 31,229).
Measurements: Office visits at which antidepressant, anxiolytic, sedative, hypnotic, antipsychotic, or mood stabilizer medications were prescribed were grouped according to participant age (21�64, ?65) and then compared within each medication class on visit characteristics. and then compared according to variables including provider type, sex, and race; presence of diagnosed mental illness; prescription of other psychotropic agents; total number of chronic conditions; time spent with physician; and total number of medications.
Results: In 2010, there were 90.3 million antidepressant office visits; 77.7 million anxiolytic/sedative/hypnotic visits; 15.5 million antipsychotic visits; and 9.5 million mood stabilizer visits. Nonpsychiatrists prescribed the majority of psychotropic medications for every class and age group; 17.3% of older adult antipsychotic visits and 44.9% of younger adult antipsychotic visits were to a psychiatrist (chi-square = 19.58, P = .001). Older adults in every medication class were less likely to have a diagnosed mental disorder.
Conclusion: Older adults prescribed psychotropic medication were less likely to have a diagnosed mental disorder than their younger counterparts. Efforts to promote quality prescribing should seek to minimize nonspecific use of psychotropic medication.
