Abstract

US hospital prices are rising again after years of limited growth. We analyze trends in hospital prices during a period of significant price growth (1999-2003) to assess whether hospitals that are part of multi-hospital systems were able to increase their prices faster than non-system hospitals. We find hospitals that were members of multi-hospital systems were able to increase their prices substantially more than comparable non-systems hospitals (34% for large systems and 17% for small systems). Further, we find that the systems effect is not confined to hospitals that have other system member hospitals in their local markets. One possible explanation is that hospitals belonging to non-local multi-hospital systems have improved their bargaining position vis-à-vis health plans.

摘要

经过数年的有限增长后，美国医院的价格再次上涨。我们分析了价格大幅增长时期（1999 - 2003年）的医院价格趋势，以评估作为多医院系统一部分的医院是否能够比非系统医院更快地提高价格。我们发现，属于多医院系统的医院能够比类似的非系统医院大幅提高价格（大型系统为34%，小型系统为17%）。此外，我们发现系统效应并不局限于在其当地市场有其他系统成员医院的医院。一种可能的解释是，隶属于非本地多医院系统的医院相对于医疗保健计划而言，其议价地位有所改善。
