OBJECTIVES: To examine the relationship between self-reported health status, prophylactic medication use, and healthcare service use in older adults with asthma.
DESIGN: A prospective longitudinal cohort study was conducted over a 2-year postenrollment period in a population of asthmatic older adults enrolled in managed care. Patients completed a comprehensive health-risk screen at time of enrollment in the plan.
SETTING: A Medicare health maintenance organization (HMO) in the southeastern United States with prescription benefit.
PARTICIPANTS: One hundred twenty-nine older adults with asthma using inhaled corticosteroid therapy as prophylaxis and enrolled in a Medicare HMO were available for complete follow-up.
MEASUREMENTS: We measured self-reported health perception, falls, lifestyle, depressive symptomatology, and pre-enrollment healthcare service use using a comprehensive risk screen. We used the Med-Total index and total annual healthcare charges as measures of postenrollment inhaled corticosteroid and healthcare service use.
RESULTS: After adjusting for the effects of other variables, we found that depressive symptomatology at baseline and increased comorbidity severity (using the Charlson comorbidity index) were associated with significant reductions in prophylactic medication possession (27% with depressive symptomatology and 6% with unit increase in Charlson's index, P <.05). Additionally, after adjusting for the effects of baseline health status, we found that a 10% increase in prophylactic medication possession was associated with a nearly 5% decrease in total annual healthcare charges in this population (P <.01).
CONCLUSION: There are strong but not fully explained associations between depressive symptoms at time of enrollment, decreased postenrollment prophylactic medication use and increased postenrollment healthcare service use in older adults with asthma.
