Statewide hospital discharge data in South Carolina for the period 1979-81 were used to evaluate the effectiveness of the incidental appendectomy performed as a preventive measure. The occurrence of incidental appendectomy exceeded that of appendicitis treated by appendectomy, with population-based rates of 1.13/1,000 and 0.97/1,000 person-years, respectively. Over 64 per cent of appendicitis cases occurred in persons under 25 years of age while 74 per cent of incidental appendectomies occurred in persons age 25 and over. Extrapolating to the nation, the data suggest that 254,250 incidental appendectomies might prevent 3,382 future cases of hospitalized appendicitis. The cost of the prevented cases is estimated as $6,764,000. The cost of the incidental appendectomies would be $20,340,000 if as many as 10 per cent of surgeons' fees were separately charged and twice as much if twice as many were so charged. Information on charges for incidental appendectomies is not readily available.
南卡罗来纳州1979 - 1981年期间全州的医院出院数据被用于评估作为预防措施进行的附带阑尾切除术的有效性。附带阑尾切除术的发生率超过了通过阑尾切除术治疗阑尾炎的发生率，基于人群的发生率分别为每1000人年1.13例和0.97例。超过64%的阑尾炎病例发生在25岁以下的人群中，而74%的附带阑尾切除术发生在25岁及以上的人群中。推断至全国范围，数据表明254,250例附带阑尾切除术可能预防3,382例未来的住院阑尾炎病例。预防病例的成本估计为676.4万美元。如果高达10%的外科医生费用单独收取，附带阑尾切除术的成本将为2034万美元，如果收取的费用翻倍，则成本将翻倍。关于附带阑尾切除术费用的信息不易获取。
