PDX Epistry

The Center for Policy and Research in Emergency Medicine (CPR-EM), housed in the Department of Emergency Medicine at Oregon Health and Science University, runs a regional cardiac arrest registry, the Portland Cardiac Arrest Epidemiologic Registry (PDX Epistry). PDX Epistry is a continuation of the local cardiac arrest registry started in 2005 as part of the larger Resuscitation Outcomes Consortium Epidemiologic Registries (ROC Epistry). The Portland metropolitan region participated in ROC Epistry and related prehospital cardiac arrest studies from 2005-2017 and has since continued a local observation cohort of cardiac arrest cases through PDX Epistry.

PDX Epistry includes extensive, detailed prehospital data for cardiac arrests occurring in the four counties surrounding the Portland, Oregon region with linkage to hospital outcomes. Data in the registry are also linked to monitor file data and medical consultation call data through our regional medical resource hospital line.

The focus of PDX Epistry is to provide high-quality epidemiologic data on trends in out-of-hospital cardiac arrest care in an extensive North American region, data for observational research, quality improvement data to local emergency medical services agencies and counties, and to provide the infrastructure for interventional prehospital trials. To achieve these goals, PDX Epistry is fortunate to partner with dozens of regional EMS agencies and hospitals similarly passionate about improving survival rates for patients suffering out-of-hospital cardiac arrest.

The current principal investigator of PDX Epistry is Dr. Joshua Lupton, a physician-scientist in the Department of Emergency Medicine at OHSU.
