Racial variation in predicted and observed in-hospital death : A regional analysis.
- To compare observed, predicted, and risk-adjusted hospital mortality rates in white and African-American patients and to determine whether, as prior studies suggest, African-American patients would have higher predicted risks of death and similar or higher risk-adjusted mortality.
- Retrospective cohort study.
- Thirty hospitals in northeast Ohio.
- A total of 88205 eligible patients consecutively discharged in the years 1991 through 1993 with the following 6 diagnoses : acute myocardial infarction, congestive heart failure, obstructive airways disease, gastrointestinal hemorrhage, pneumonia, and stroke.
- We measured predicted risks of death at admission for each diagnosis using validated multivariable models based on standard clinical data abstract ed from patients medical records.
We then adjusted in-hospital mortality rates in white and African-American patients for predicted risk of death and other covariates using logistic regression analysis.
Main Outcome Measures
- Predicted risk of death at admission and observed hospital mortality in white and African-American patients.
- Predicted risks of death were lower (P<. 001) in African Americans for 4 of the 6 diagnoses.
Adjusted odds of hospital death were lower (P<. 01) in African Americans for 2 of the 6 diagnoses (congestive heart failure and obstructive airways disease) and similar for the other 4 diagnoses. (...)
