The authors analyzed the potential financial impact of paying general hospitals on the basis of diagnosis-related groups (DRGs) for Medicare alcohol-drug abuse and psychiatric admissions. Average costs per admission were substantially higher for general hospitals with special psychiatric units that are currently exempt from the prospective payment system (PPS) than for hospitals without exempt units. Simulations of DRG-related payments indicated that these payments would be greater for admissions to hospitals with exempt psychiatric units than for admissions to hospitals without exempt units. However, the differences in costs between these two types of facilities were greater than the differences in payments that would occur under a PPS.
作者分析了按照诊断相关分组（DRG）向综合医院支付医疗保险酒精药物滥用和精神科住院费用的潜在财务影响。目前免于按病种付费制度（PPS）的设有特殊精神科病房的综合医院，每次住院的平均费用显著高于没有豁免病房的医院。与DRG相关的支付模拟表明，有豁免精神科病房的医院的住院支付将高于没有豁免病房的医院。然而，这两种类型设施之间的成本差异大于PPS下支付的差异。
