Abstract

Cluster analysis Comparative studies Intensive care Racial differences Regression analysis
The purpose of this paper is to determine if racial and ethnic variations exist in intensive care (ICU) use during terminal hospitalizations, and, if variations do exist, to determine whether they can be explained by systematic differences in hospital utilization by race/ethnicity. The authors used 1999 hospital discharge data from all nonfederal hospitals in Florida, Massachusetts, New Jersey, New York, and Virginia. The authors identified all terminal admissions (N=192,705) among adults. They calculated crude rates of ICU use among non-Hispanic whites, blacks, Hispanics, and those with "other" race/ethnicity. The authors performed multivariable logistic regression on ICU use, with and without adjustment for clustering of patients within hospitals, to calculate adjusted differences in ICU use and by race/ethnicity. They explored both a random-effects (RE) and fixed-effect (FE) specification to adjust for hospital-level clustering. The data were collected by each state. ICU use during the terminal hospitalization was highest among nonwhites, varying from 64.4% among Hispanics to 57.5% among whites.
