REGULATION AND DRG EFFECTS ON HOSPITAL MORTALITY RATES

这项研究将检查医院结果在多大程度上， 根据住院死亡率和再住院率衡量， 与金融机构面临的市场和监管环境有关 医院。它还将探讨组织战略的作用 在确定市场和监管因素对 住院结果。 市场上550个系统和900家竞争对手医院的数据库 覆盖全国45个州的地区已经集结。 这些医院的成本、资源、竞争、DRG等数据 指数、医院战略和医院结果 收集了1983-84年的数据，有些变量更新到了1986年。 将收集1987-88年度的死亡率和再入院数据 如有需要，将更新其他数据。一种效果模型 DRGs、市场价格竞争和医院战略 将使用这些数据指定和测试患者的结果。 这一分析将提供关于 医院行为中的市场和战略因素 这种行为对医院结果的影响。它还将提供 年调整后的医院死亡率数据的趋势信息 自引入联邦医疗保险预期付款以来的一段时间。

This research will examine the extent to which hospital outcomes, as measured by hospital mortality and readmission rates, are related to the market and regulatory environment faced by the hospital. It will also explore the role of organizational strategy in determining the effects of market and regulatory factors on hospital outcomes. A database for 550 system and 900 competitor hospitals in market areas covering 45 states across the country has been assembled. For these hospitals data on costs, resources, competition, DRG indexes, hospital strategies and hospital outcomes have been collected for 1983-84 and, for some variables, updated to 1986. Mortality and readmission data will be collected for 1987-88 and where necessary other data will be updated. A model of the effects of DRGs, market price competition and hospital strategies on patient outcomes will be specified and tested using these data. The analysis will provide valuable information on the role of market and strategy factors in the behavior of hospitals and the effect of that behavior on hospital outcomes. It will also provide information on trends in adjusted hospital mortality data in the period since the introduction of Medicare prospective payment.
