This study is a retrospective examination of data from a prepaid group practice that introduced a change in surgical services so that about 35 per cent of patients having surgery in the operating room were not admitted to the hospital. The study population is the membership of the Oregon Region of the Kaiser Foundation Health Plan for the period 1966 through 1974. The data come from 100 per cent of the hospital admissions and 100 per cent of the ambulatory (nonadmit) surgical procedures. This study examines the costs, quality of care, and satisfaction of providers and patients with ambulatory surgery. Cost savings for the ambulatory procedures averaged +192.19 per procedure (based on 1977 costs). National savings for 1977 were projected at +773,947,208. In addition, ambulatory surgery absorbed an increasing demand for surgical procedures without requiring additional hospital beds. No difference in quality of care were found for inpatients and ambulatory patients (both used the same operating rooms and staff), and both providers and patients were found to be very satisfied with ambulatory surgery services.
本研究是对一家预付费团体医疗实践机构的数据进行的回顾性分析，该机构对手术服务进行了一项变革，使得在手术室接受手术的患者中约35%无需住院。研究人群为1966年至1974年期间凯撒基金会健康计划俄勒冈地区的会员。数据来自100%的住院病例以及100%的门诊（非住院）手术程序。本研究考察了门诊手术的成本、护理质量以及医疗服务提供者和患者的满意度。门诊手术的成本节约平均为每项手术192.19美元（基于1977年的成本）。预计1977年全国节约金额为773,947,208美元。此外，门诊手术在无需增加医院床位的情况下，满足了日益增长的手术需求。住院患者和门诊患者的护理质量未发现差异（二者使用相同的手术室和工作人员），且医疗服务提供者和患者均对门诊手术服务非常满意。
