Advanced Practice Providers (APPs) are among the most clinically flexible groups of health care professionals. They consist of physician assistants (PAs), nurse practitioners (NPs), certified registered nurse anesthetists (CRNAs), and certified nurse midwives (CNMs).

Not only are APPs the primary health care providers in many clinical settings, they also have skill sets which make them strategically important.

Tammy Eaton, CRNP

Tammy Eaton, CRNP, has worked for nearly seven years as a nurse practitioner at UPMC Mercy. She first worked within the Palliative and Supportive Institute team and is currently in the Department of Critical Care Medicine.

She earned her nursing degree from Ohio Valley General Hospital School of Nursing and her bachelor’s and master’s degrees in nursing from Carlow University. She is currently a PhD candidate at the University of Pittsburgh. Her dissertation focuses on exploring the role of primary palliative care in critical illness survivors.

Tammy has proven to be an essential member of the care team at UPMC and has been driven to help patients achieve the best possible outcome. She was instrumental in the creation of the Critical Illness Recovery Center (CIRC) at UPMC Mercy with funding from the Beckwith Institute.

At the CIRC, Tammy and her colleagues provide multidisciplinary care for critical illness survivors who are at risk for or are suffering from post-intensive care syndrome (PICS). Since opening in 2018, the CIRC has become an international model for delivering care to critical illness survivors.

In addition to her work at UPMC, Tammy is also a founding member and serves as an executive leader for the Critical and Acute Illness Recovery Organization (CAIRO). The organization is an international consortium of active clinical programs working to advance practice and science of critical and acute illness recovery.

APPs are critical in a health care system, especially in the event of a health crisis like the COVID-19 pandemic. At UPMC, we want to thank all APPs for their dedication and hard work and for delivering high-quality care to our patients each day.
