This study, like two earlier studies by the author, examines the effects of changing medical technologies on medical care costs by comparing the costs of treatment of a number of common illnesses at two points in time, 1971 and 1981. While the earlier studies, covering the periods 1951-1964 and 1964-1971, showed that the main cost-raising changes had been a steep rise in the use of relatively low-cost ancillary services, such as laboratory tests and x-rays ("little-ticket" technologies), this study shows that in the period 1971-1981 the use of these technologies hardly changed but that several new and expensive technologies ("big-ticket" technologies) came into use, which raised medical care costs considerably.
与作者之前的两项研究一样，本研究通过比较1971年和1981年两个时间点上多种常见疾病的治疗成本，考察了医疗技术变革对医疗成本的影响。早期的研究涵盖了1951 - 1964年和1964 - 1971年这两个时期，结果显示，主要的成本上升变化是相对低成本的辅助服务（如实验室检查和X光检查，即“小费用”技术）的使用急剧增加；而本研究表明，在1971 - 1981年期间，这些技术的使用几乎没有变化，但有几种新的、昂贵的技术（“大费用”技术）开始投入使用，这使得医疗成本大幅上升。
