Cambridge Health Authority accepted the gift of a whole body computed tomography (CT) scanner and radiotherapy planning system for Addenbrooke's Hospital (AH) from a local charity in 1981. The charity was to provide funds for the maintenance and all running costs for the first 5 years. Acceptance of the gift was conditional on an evaluation of the use of body CT before any decision about subsequent funding was made. The results of this evaluation are presented here. A detailed assessment fo 150 consecutive CT studies was performed together with an audit of CT use. The costs of running the CT unit and an indirect measurement of the benefits brought about by body CT were evaluated. In 86% of patients the CT findings were considered likely to have a great contribution to clinical management; in less than 10% was little or no benefit likely. In most patients (68%) CT was considered to have been more useful than any alternative test(s) would have been. The total cost of CT during the financial year 1983-84 was 219,163 pounds and the average cost per CT study was 73 pounds. The assessment indicated annual benefits fo 673,385 pounds including the saving of 3,880 inpatient bed days, 760 outpatient visits and alternative tests costing 290,684 pounds p.a. Some corroborative evidence that these benefits have occurred is presented. This study suggests a cost benefit ratio of 1:3.07.
1981年，剑桥卫生局接受了当地一家慈善机构为阿登布鲁克医院（AH）捐赠的一台全身计算机断层扫描（CT）扫描仪和放射治疗计划系统。该慈善机构将在前5年提供维护资金和所有运营成本。接受这份礼物的条件是在决定后续资金之前对身体CT的使用情况进行评估。本文展示了此次评估的结果。对连续150例CT研究进行了详细评估，并对CT的使用情况进行了审计。评估了CT设备的运营成本以及对身体CT带来的益处的间接衡量。在86%的患者中，CT检查结果被认为可能对临床管理有很大贡献；不到10%的患者可能获益很少或没有获益。在大多数患者（68%）中，CT被认为比任何其他替代检查都更有用。1983 - 1984财政年度CT的总成本为219,163英镑，每次CT检查的平均成本为73英镑。评估表明年度收益为673,385英镑，包括节省3,880个住院床位日、760次门诊就诊以及每年花费290,684英镑的替代检查。还提供了一些这些益处已经出现的佐证证据。这项研究表明成本效益比为1:3.07。
