Center for Policy and Research in Emergency Medicine (CPR-EM)


The OHSU Center for Policy and Research in Emergency Medicine's breakthrough research leads to new standards of care and a better understanding of important issues involving emergency medicine, disaster preparedness, and toxicology.

At the OHSU Center for Policy and Research in Emergency Medicine (CPR-EM), our mission consists of reducing inequities, including, but not limited to, those based on race, ethnicity, gender, sexual orientation, gender identity, immigration status, religion, and disability. In particular, we acknowledge the legacy of racism that is embedded in American society and institutions, and we are actively working to be catalysts of change to dismantle these harmful structures. Our commitment involves reflecting principles of equity across all functions of our organization, including in its culture, governance, hiring practices, salaries, research areas of focus, and the conduct of our research.

Dr. Esther Choo, Director of Equity and Inclusion in the Department of Emergency Medicine, OHSU

10/27/2020 - Congratulations to Dr. Esther Choo, who was appointed the first Director of Recruitment, Equity, and Inclusion (DREI) for the Department of Emergency Medicine.  In her new role, Dr. Choo will lead, coordinate, track, measure and assess the collective efforts of our team.  Dr. Choo will share her expertise to develop a diverse applicant pool when recruiting, and to ensure that the Department of Emergency Medicine (DEM) is one where a diverse faculty and staff can thrive and advance.  Dr. Choo will also promote continuous learning and education on diversity, anti-racism, unconscious bias, and equity.

The DEM and CPR-EM strive to support diversity, equity, and inclusion and foster a culture where everyone can operate at the top of their potential.

The CPR-EM faculty and staff are honored to have Dr. Choo as an integral member of our team, and are thrilled that Dr. Choo has been appointed to this new role within the department.  Dr. Choo has been and continues to be a strong advocate for equity, inclusion, and culture change, contributing to movements such as #TimesUpHealthCare.

C3PO - Clinical Trial of COVID-19 Convalescent Plasma of Outpatients

In August 2020, the OHSU ED began enrolling in the C3PO trial which is designed to confirm or refute the role of passive immunization as a safe and efficacious therapy in preventing the progression from mild to severe/critical COVID-19 illness and to understand the immunologic kinetics of anti-SARS-CoV-2 antibodies after passive immunization. 

What does that mean?  If you present to the OHSU ED, and are confirmed to have contracted COVID-19, you may be asked to participate in this trial.  Patients who participate will receive either Conalenscent Plaslma (CP) or a Placebo (saline and multi-vitamin infusion).  The study staff will talk with you before you are enrolled in this trial so you can decide if you would like to participate.  Participating in research is always voluntary, and the research team will give you the information you need to decide if you would like to participate. 

OHSU C3PO Press release

Survey of ED patients with COVID-like Symptoms

Drs. Newgard and Choo are leading a study to learn more about the clinical course and outcomes of patients with symptoms potentially consistent with a viral illness such as COVID-19, and to help guide health systems and emergency departments during the current pandemic.  If you visit the OHSU, Doernbecher, Tuality, or Columbia Memorial Hospital Emergency Departments and you are evaluated for COVID, or have any symptoms of a COVID-like illness, you may receive a request (via text or email) from the study team to complete a weekly survey for up to 30 days after your visit. To participate in this study, you DO NOT need to be COVID-19 positive, or even need to have been evaluated for COVID-19.   If you have questions about this study please contact

This study is being overseen by the OHSU IRB (#21302).  You may also contact the IRB at

Dana Zive

It is with a heavy heart that we announce the passing of our esteemed colleague,  Dana Zive, Sunday, September 30, 2018.

 Dana was the Director of the Oregon POLST Registry, Associate Director of the OHSU Center for Ethics in Health Care, and a Research Assistant Professor in the OHSU Department of Emergency Medicine and CPR-EM.  She earned her B.S. in Environmental Chemistry and Toxicology at the University of Nevada, Reno, and her M.P.H. in Public Health Education and Biostats/Epidemiology from San Jose State University.  Dana joined OHSU in 2004, and her areas of focus included end-of-life care and emergency care research. 

 Dana was integrally involved in many DEM research efforts, including the Resuscitation Outcomes Consortium (many out-of-hospital interventional trials in cardiac arrest and trauma) and the Physician Orders for Life-Sustaining Treatment Program (POLST).  She was key in developing and implementing the Oregon electronic POLST registry, including legislated state funding. Dana has been a fundamental member of CPREM throughout our years of building infrastructure and growth.  She had a true research mind and a passion for data. She was our colleague and friend and will be dearly missed. 

Dana is survived by her husband and daughter (Lola, 8).   If you have a story about Dana you would like to share with her family, please send your thoughts to
