Abstract
Drug utilization evaluation is an effective mechanism to identify individual variability in drug use and to promote interventions that will improve patient outcomes. The present analysis is a novel approach incorporating medical claims information with pharmacy data. This analysis was conducted during the 12 months of 1993 in four health maintenance organizations with approximately 673,000 members. Health care costs were identified in asthmatic patients, age 7 years and over, who used high doses of inhaled beta-adrenergic agonists, defined as more than 8 puffs per day. A total of 20,512 asthmatic patients were identified. From these patients, 1093 members or 5.3% received high doses of an inhaled bronchodilator. This second group was then stratified by concurrent use of inhaled anti-inflammatory therapy. Group A, 32% of the members, received > or = 4 puffs per day of an anti-inflammatory medicine; group B, 31% of the members, received <4 puffs per day of these medicines; and group C, 37% of the members, received no anti-inflammatory therapy. Examination of the linked medical claims and pharmacy database demonstrated that members using high doses of inhaled bronchodilators had annual charges for treatment related to their asthma...Continue Reading
