This paper measures current patterns of hospital segregation among Medicare beneficiaries.
Data from the fiscal year 1993 Medicare Provider Analysis and Review (MEDPAR) file, the index of dissimilarity, and a linear regression model are used to test the effects of standard metropolitan area characteristics on hospital segregation.
The overall hospital segregation index was 0.529, ranging by state from 0.154 to 0.746. Hospital segregation in 126 standard metropolitan areas was positively related to population size, hospital density, and residential segregation and negatively related to income inequities and location in the South.
Racial segregation remains high and may produce both reporting biases and unequal effects of public policy.
本文衡量了医疗保险受益人中目前的医院隔离模式。
使用1993财年医疗保险提供者分析与审查（MEDPAR）文件的数据、差异指数和线性回归模型来检验标准大都市地区特征对医院隔离的影响。
整体医院隔离指数为0.529，各州范围从0.154至0.746。126个标准大都市地区的医院隔离与人口规模、医院密度和居住隔离呈正相关，与收入不平等和位于南部呈负相关。
种族隔离仍然很高，可能会产生报告偏差和公共政策的不平等影响。
