CAN DATA ENVELOPMENT ANALYSIS PROVIDE A SCALAR INDEX OF ‘VALUE’?
研究用数据包络分析将风险调整后的成本作为投入、多项质量指标作为产出，检验医生诊所的投入效率是否与更高质量和更低成本相关，为基于价值的支付系统提供标量价值指标。
The concept of 'value' typically includes a combination of cost and quality measures. Some approaches to incorporating value into payment systems treat cost and quality as separate dimensions, but policymakers have expressed interest in a single scalar index that combines cost and quality. Treating risk-adjusted cost as an input and multiple measures of quality as outputs, we examine whether data envelopment analysis input efficiency is associated with higher quality and lower cost in a sample of physician practices using 2008 US Medicare claims data from Colorado. The findings suggest that input efficiency might provide a useful scalar measure of value for a value-based payment system for physician services.
