Hospital capacity has declined in recent years and is forecast to decline further. The objective of this study is to determine if hospital capacity has declined more rapidly in metropolitan statistical areas (MSAs) with high HMO market penetration compared with MSAs with low HMO market penetration in the period from 1982 to 1996. The findings presented in this study are that greater reductions in beds per capita occur in MSAs with greater HMO penetration, but the magnitude of the differences is small. Reductions in other measures of hospital capacity--hospital closures, beds per hospital, and occupancy--are not consistently associated with HMO market penetration. Bed capacity occurs at roughly similar rates in all MSAs.
近年来医院的容量有所下降，并且预计还会进一步下降。本研究的目的是确定在1982年至1996年期间，与健康维护组织（HMO）市场渗透率低的大都市统计区（MSA）相比，HMO市场渗透率高的MSA中，医院容量的下降速度是否更快。本研究给出的结果是，HMO渗透率较高的MSA中人均病床的减少幅度更大，但差异幅度较小。医院容量的其他衡量指标——医院关闭、每家医院的病床数和床位占用率——的下降与HMO市场渗透率并无一致关联。所有MSA的床位容量下降速度大致相似。
