摘要
BACKGROUND: Little is known about the economic impact of the acid-related disorders (ARDs), which include dyspepsia, gastritis, gastroesophageal reflux disease (GERD), and peptic ulcer disease (PUD), in managed care patient populations. OBJECTIVES: TO describe the prevalence of medically attended ARDs, and their direct medical costs from the perspective of a large health maintenance organization (HMO). METHODS: A total of 1,550 ARDs subjects (age greater than or equal to 18 years), were randomly sampled from outpatient diagnosis and pharmacy databases of the Kaiser Permanente Medical Care Program of Northern California and verified by chart review. Five age-and gender-matched controls were identified per subject. One-year prevalence, excess annual costs, and initial 6-month costs for incident cases were estimated using the HMO cost accounting system. RESULTS: Total ARDs prevalence (5.8%) increases with advancing age. GERD is the most common ARD (2.9% overall prevalence). Annual per person attributable costs were $1,183, $471, and $431 respectively for PUD, GERD, and gastritis/dyspepsia. Excess inpatient costs for PUD explain its higher costs. Outpatient costs were somewhat higher for GERD ($279) than for PUD or gastritis/dyspepsia. Pharmacy costs were relatively low for each condition, in part because many patients were treated with generic cimetidine. Total annual HMO expenditures for ARDs were $59.4 million, with 40.6%, 36.8%, and 22.6% respectively for GERD, PUD, and gastritis/dyspepsia. CONCLUSIONS: Acid-related disorders, particularly GERD and PUD, contribute substantially to the direct costs of medical care in this managed care population. (C) 1997 by Excerpta Medica, Inc.
