This report presents estimates of surgical and nonsurgical procedures performed in the United States during 1996. Data are presented by characteristics of patients, region of the country, and procedure categories for ambulatory and inpatient procedures separately and combined.
Estimates in this report are based on data collected from the National Hospital Discharge Survey (NHDS) and the National Survey of Ambulatory Surgery-(NSAS). NHDS provides data on hospital inpatient care, and NSAS provides data on ambulatory surgery in hospitals and in freestanding ambulatory surgery centers. For NHDS, data were collected for approximately 282,000 discharges from 480 non-Federal short-stay hospitals (95 percent response rate). For NSAS, data were collected for approximately 125,000 ambulatory surgery discharges from 488 hospitals and freestanding ambulatory surgery centers (81 percent response rate).
An estimated 71.9 million procedures were performed on 39.9 million discharges from hospitals and freestanding ambulatory surgery centers during 1996: 40.4 million procedures were for inpatients, and 31.5 million were for ambulatory patients. Females had more procedures than males, and the rate of procedures increased with age in ambulatory and inpatient settings. The leading procedures for ambulatory surgery patients and inpatients combined were arteriography and angiocardiography, endoscopy of small intestine, endoscopy of large intestine, and extraction of lens.
本报告呈现了1996年美国实施的外科手术和非外科手术的估计数据。数据按患者特征、美国地区以及门诊手术和住院手术的手术类别分别及合并呈现。
本报告中的估计数据基于从国家医院出院调查（NHDS）和国家门诊手术调查（NSAS）收集的数据。NHDS提供医院住院护理数据，NSAS提供医院和独立门诊手术中心的门诊手术数据。对于NHDS，从480家非联邦短期住院医院收集了约282,000例出院病例的数据（回复率为95%）。对于NSAS，从488家医院和独立门诊手术中心收集了约125,000例门诊手术出院病例的数据（回复率为81%）。
1996年，估计在医院和独立门诊手术中心的3990万例出院病例中实施了7190万例手术：4040万例手术为住院患者实施，3150万例为门诊患者实施。女性接受的手术比男性多，在门诊和住院环境中，手术率均随年龄增长而增加。门诊手术患者和住院患者合并后的主要手术包括动脉造影和心血管造影、小肠内镜检查、大肠内镜检查以及晶状体摘除术。
