Heart failure & cardiomyopathies
Relationship Between Hospital Team Segregation Index, Heart Failure, and Ischemic Heart Disease
Authors' conclusion
Among Black vs White patients, HF outcomes did not vary by SI tertiles. However, in IHD, SI impacted Black patients' risk of readmission and survival.
Study context
- Population
- Black and White patients admitted with primary diagnoses of heart failure (HF) or ischemic heart disease (IHD) from 2010 to 2018patients analyzed, by diagnosis · HF (29.4% Black, 70.6% White) 119,272 · IHD (17.9% Black and 82.1% White) 183,165
- Comparison
- Black vs White patients across hospital segregation index (SI) tertiles
- Outcome
- Receipt of a cardiologist's care, HF
Methodological detailshospitals grouped by SI tertile
- Hospitals grouped by SI tertile
Main finding
As reported in the abstract
- Across SI tertiles, Black patients with HF had lower odds of receiving a cardiologist's care compared to White patients

Readmission and 1-year survival, HF
- Across SI tertiles and cardiology care, no difference in the hazard of readmission by race; odds of 1-year survival were higher for Black patients
Receipt of cardiology care, IHD
- No difference in odds of receiving cardiology care between races across SI tertiles
