title: Cost of acid peptic disorders in a managed-care organization.
abstract: The purpose of this study was to determine the cost of managing ambulatory patients with symptoms of acid peptic disorders in a managed-care organization under actual clinical conditions. Study data were collected in a large independent practice association model health maintenance organization in Gainesville, Florida, from prescription records maintained in a computerized database and from patient medical records. Patients had to be started on a histamine2-receptor antagonist (H2RA) or the proton pump inhibitor omeprazole between 1992 and 1994. A total of 113 patients qualified for inclusion in the study; 57 received H2RAs, 27 received omeprazole, and 29 received combination therapy. The costs of procedures, physician visits, and drug therapy were considered in the economic evaluation. Costs were evaluated using two methods: the capitation total cost (CTC) and the fee-for-service total cost (FSTC). The mean CTC and FSTC for managing a patient with acid peptic symptoms for 6 months were $382 +/- 356 (range, $14 to $1820) and $456 +/- 368 (range, $52 to $1925), respectively. Drug costs represented 52% of the total FSTC and 62% of the total CTC. Drug costs were followed by the costs for encounters with primary care physicians, endoscopy, referral to specialists, and upper gastrointestinal (UGI) tract procedures. Documented outcomes were available for 85 patients. Compared with patients receiving H2RAs (n = 41), patients receiving omeprazole (n = 18) had significantly lower FSTCs ($317 +/- 219 compared with $423 +/- 307, respectively); diagnostic testing costs (for endoscopy, $0 compared with $44 +/- 119, respectively; for UGI procedures, $22 +/- 42 compared with $55 +/- 54, respectively); physician encounter costs ($66 +/- 40 compared with $86 +/- 38, respectively); and referral to specialist costs ($0 compared with $18 +/- 60, respectively). Patients receiving omeprazole also had more positive clinical outcomes than patients receiving H2RAs (78% compared with 49%, respectively), resulting in a more favorable cost of producing a successful outcome compared with patients receiving an H2RA. The cost of success was $407 for patients treated with omeprazole compared with $869 for patients treated with H2RAs. The findings of this analysis conducted under actual clinical conditions support findings of randomized clinical trials showing the cost-effectiveness of proton pump inhibitors.
