Debate persists about the most effective way to pay hospitals to limit health care cost inflation. New Jersey, the first state to adopt the DRG payment system, has accumulated sufficient experience to allow a comparison of the relative efficacy of two reimbursement methods. Regression results, using a time trend specification, indicate that per case payment based on diagnosis related groups was no more successful in controlling hospital costs per capita than a previous per diem payment system. There were, however, significant changes in costs per case and length of stay. But the increase in admission rates neutralized the reduction in costs per case. There were no significant overall cost savings.
关于支付医院费用以限制医疗保健成本上涨的最有效方式，争论仍在继续。新泽西州是首个采用诊断相关分组（DRG）支付系统的州，已经积累了足够的经验，能够对两种报销方法的相对有效性进行比较。使用时间趋势规范的回归结果表明，与之前的每日支付系统相比，基于诊断相关分组的按病例支付在控制人均医院成本方面并不更成功。然而，每个病例的成本和住院时间有显著变化。但入院率的上升抵消了每个病例成本的下降。总体上没有显著的成本节省。
