How expanding artery-opening (PCI) procedures affects disadvantaged versus other communities
Official title: Expansion of Percutaneous Coronary Intervention in Outpatient and Inpatient Settings: Quantifying the Differential Impact Between Disadvantaged and Non-Disadvantaged Communities
Funded at University of California, San Francisco · NIH-11135312 · Data updated 2026-11-12
This project looks at whether expanding artery-opening procedures (PCI) in hospitals and outpatient centers has helped or left behind people from disadvantaged communities with heart disease.

Who could benefit from this research
✓Could help
The people included are patients in California who had acute heart attacks or received PCI during the study years, especially those from low-income, uninsured, or racial/ethnic minority communities.
✕Less likely to help
People without coronary artery disease or those treated outside California are unlikely to be directly affected by this project.
What this research studies
From a patient perspective, researchers will use 10 years of individual patient records from California to compare who got PCI (stents/angioplasty) and how patients did afterward in disadvantaged versus non-disadvantaged communities. They will look at both procedures done in hospitals and those done in outpatient settings to see if growth in these services changed access, treatment, or outcomes for different groups. The team will link treatment patterns to community measures like income, insurance, and race to pinpoint system-level causes of disparities. No new clinic visits are required because the work uses existing medical records and administrative data.
Why it matters
Potential benefit: If successful, the work could identify ways to make access to PCI more equitable so disadvantaged patients get timely treatment and better outcomes.
How similar studies have gone: Previous research has shown unequal access to PCI across groups, but using PCI expansion over time to reveal system-level drivers of disparities is a relatively new approach.
