Abstract
One problem noted recently with the diagnosis-related group payment system is that the distribution of Medicare case weights and case-mix indexes are compressed; that is, the payment rates for high-cost procedures are too low and those for low-cost procedures are too high. Despite the attention compression has received, there are no direct estimates of its magnitude or importance. Presented in this article are an empirical test for compression and a suggestion for a simple correction to decompress the relative prices.
摘要
最近发现的与诊断相关分组支付系统有关的一个问题是，医疗保险病例权重和病例组合指数的分布被压缩了；也就是说，高成本程序的支付率过低，而低成本程序的支付率过高。尽管压缩问题已受到关注，但尚无对其规模或重要性的直接估计。本文给出了对压缩的实证检验以及对相对价格进行简单校正以解除压缩的建议。
