Hospital Allocation and Racial Disparities in Health Care

Area of Science:

• Health services research
• Health equity
• Cardiovascular medicine

Background:

• Racial disparities in healthcare persist, with Black patients often receiving care at lower-quality hospitals.
• Understanding the drivers of these disparities is crucial for developing effective interventions.

Purpose of the Study:

• To develop a framework for measuring hospital allocation's role in racial disparities for heart attack patients.
• To analyze trends in hospital performance and patient allocation over two decades.

Main Methods:

• Developed a novel framework to quantify hospital allocation's impact on racial disparities.
• Analyzed data on Black and white heart attack patients' hospital assignments and outcomes.
• Examined changes in hospital performance and patient reallocation over a 20-year period.

Main Results:

• Black patients were disproportionately treated at lower-performing hospitals compared to white patients.
• A significant reduction (over two-thirds) in the hospital performance gap was observed over two decades.
• This reduction was primarily attributed to rapid performance improvement at hospitals serving Black patients, rather than patient reallocation.
• Hospital improvement correlated with the adoption of beta blockers.

Conclusions:

• Hospital performance improvement, particularly linked to the adoption of treatments like beta blockers, is a key driver in reducing racial disparities in heart attack care.
• While hospital allocation plays a role, focusing on improving care quality at existing facilities is a more effective strategy for disparity reduction.
• Future efforts should leverage both performance improvement and strategic reallocation to further reduce healthcare inequities.
