A nonparametric data envelopment analysis (DEA) is performed on hospitals in the federal state of Saxony (Germany) and in Switzerland. This study is of interest from three points of view. First, contrary to most existing work, patient days are not treated as an output but as an input. Second, the usual DEA assumption of a homogeneous sample is tested and rejected for a large part of the observations. The proposed solution is to restrict DEA to comparable observations in the two countries. The finding continues to be that hospitals of Saxony have higher efficiency scores than their Swiss counterparts. The finding proves robust with regard to modifications of DEA that are motivated by differences in hospital planning in Germany and Switzerland.
对德国萨克森州和瑞士的医院进行了非参数数据包络分析（DEA）。本研究从三个角度来看都很有意义。首先，与大多数现有研究不同，患者住院天数不作为产出而是作为投入来处理。其次，对DEA中同质性样本这一常见假设进行了检验，结果发现大部分观测值并不满足该假设。建议的解决方案是将DEA限制在两国具有可比性的观测值上。研究结果仍然是，萨克森州的医院效率得分高于瑞士的医院。这一发现对于因德国和瑞士医院规划差异而对DEA进行的修改而言依然稳健。
