医院每年用于检测的费用巨大。为了解这些费用的使用情况,作者在波士顿某医院对1 000名住院病人所接受的32 206次诊断性检查做随机抽样费用研究。发现高费用(超过100美元)检查约占全部检查费用的50%,但其数量仅占全部检查的4%。作者认为;高费用检查在遏制检查费用中意义重大,应使其得到充分有效的使用。 The cost of the hospital for testing every year is huge. In order to understand the use of these costs, the author conducted a random sample of the cost of 32,206 diagnostic tests for 1,000 inpatients at a hospital in Boston. It was found that high-cost (more than US$100) inspections accounted for about 50% of all inspection costs, but their number accounted for only 4% of all inspections. The author believes that high-cost inspections are of great significance in checking the cost of inspections and should be used fully and effectively.
