Factors associated with suboptimal analgesic use in community-dwelling elderly

OBJECTIVE: To examine patterns and factors associated with overall and suboptimal analgesic use among community-dwelling elderly. DESIGN: Cross- sectional survey. SETTING: Five-county urban and rural region in Piedmont, NC. PARTICIPANTS: A stratified random sample from the Duke Established Populations for Epidemiologic Studies of the Elderly of 3973 participants aged 65 years or older. MAIN OUTCOME MEASURES: Use of any analgesic medication, suboptimal analgesic use (taking 2 or more analgesics from the same class, using 3 or more analgesics concurrently, or use of an analgesic that has a major interaction with another drug). RESULTS: Analgesics were used by 60.4% of the participants. Use was more likely for those who had physical functional impairment, a history of cardiovascular disease, one or more health visits in the previous year, or were female. Use was less likely for older participants and for African-Americans with adequate financial status. Suboptimal use occurred for 9.2% of analgesic users. Therapeutic duplication was more likely in those who were depressed, needed help with basic activities of dally living, or used alcohol, and was less likely in those with adequate financial status. Multiple analgesic use was more likely in those who were depressed, had impaired physical functional status, had one or more health visits in the previous year, were African-American (of either sex), or were white women. Only two persons had a potential major analgesic- drug interaction. CONCLUSIONS: Suboptimal analgesic use is common in community-dwelling elderly, and its risk is consistently increased in those who are depressed or have impaired functional status.
