This study measures the impact of information technology (IT) use on hospital operating costs during the late 1980s and early 1990s. Using a proprietary eight-year panel dataset (1987-1994) that catalogues application-level automation for the complete census of the 3000 U.S. hospitals with more than 100 beds, this study finds that both financial/administrative and clinical IT systems at the most thoroughly automated hospitals are associated with declining costs three and five years after adoption. At the application level, declining costs are associated with the adoption of some of the newest technologies, including systems designed for cost management, the administration of managed care contracts, and for both financial and clinical decision support. The association of cost declines with lagged IT as well as the cost patterns at the less automated hospitals both provide some evidence of learning effects.
本研究旨在衡量 20 世纪 80 年代末至 90 年代初期间信息技术 (IT) 使用对医院运营成本的影响。本研究使用了一个专有的八年面板数据集（1987-1994 年），该数据集记录了美国 3000 家拥有 100 张以上床位的医院中完整的普查应用级别的自动化，研究发现，在最全面实现自动化的医院中，财务/管理和临床 IT 系统在采用后的三到五年内与成本下降相关。在应用层面，成本下降与采用一些最新技术相关，包括用于成本管理、管理式医疗合同管理以及财务和临床决策支持的系统。成本下降与滞后的 IT 以及不太自动化的医院的成本模式之间的关联都为学习效应提供了一些证据。
