Does the Expansion of Hospitals with Percutaneous Coronary Intervention (PCI) Capacity have Differential Effects on Procedure Volume and Outcomes for Heart Attack Patients in Advantaged and Disadvantaged Communities?
Using all-payer patient discharge data from California between 2006 and 2019, we propose to look at the following:
• Has the probability of being treated at low PCI-volume hospitals changed over time differentially between hospitals serving disadvantaged and advantaged communities?
• Have disparities in treatment and health outcomes between those treated in low-volume and high-volume PCI hospitals grown over time?
• Does the extent of disparities in treatment and health outcomes between those treated in low-volume and high-volume PCI depend on whether the patients are in disadvantaged or advantaged communities?
