Research & Publications

The Cardiac Care Outcomes Assessment Program has over 22 years of data collected from every hospital in Washington State that performs PCI or adult cardiac surgery. We add over 15,000 PCI records and almost 5,000 cardiac surgery records each year, which creates a wealth of data for asking research questions that are relevant and urgent to the quality and future of cardiac care.

If you would like to be involved in research initiated by the COAP Research Subcommittee contact Dr. Ravi Hira, COAP Medical Director, at rhira@qualityhealth.org.

You may also submit an application for use of COAP data in your research. To obtain a research proposal application, go here
