This paper applies a new methodology to the study of hospital efficiency and quality of care. Using a data set of hospitals from several states, we jointly evaluate desirable hospital patient care output (e.g., patient stays) and the simultaneous undesirable output (e.g., risk-adjusted patient mortality) that occurs. With a DEA based approach under two different sets of assumptions, we are able to include multiple quality indicators as outputs. The results show that lower technical efficiency is associated with poorer risk-adjusted quality outcomes in the study hospitals. They are consistent with other studies linking poor quality outcomes to higher cost.
本文将一种新方法应用于医院效率和医疗质量的研究。利用来自几个州的医院数据集，我们联合评估了理想的医院患者护理产出（如患者住院天数）以及同时出现的非理想产出（如风险调整后的患者死亡率）。在两种不同假设集下基于数据包络分析（DEA）的方法中，我们能够将多个质量指标纳入产出。结果表明，在研究的医院中，技术效率较低与风险调整后的质量结果较差相关。这些结果与其他将质量结果不佳与成本较高联系起来的研究一致。
