Expertise: Emergency Medicine


Peter Hill, M.D., FACEP, joined the faculty in 1998 as assistant chief of service after serving as chief resident. He co-founded the department’s Emergency Acute Care Unit, where he still serves as medical director. He is also the physician leader of the Department of Emergency Medicine’s Mid-Level Provider Group, consisting of nurse practitioners and physician assistants who work in all three of the department’s clinical venues. He became clinical director for the department in 2005 and was promoted to the role of vice chair of clinical affairs for the department in 2012.

Dr. Hill is also actively involved in the areas of emergency department operations, delivery of service, patient satisfaction, risk management and quality improvement. He co-led restructuring of the department’s triage and patient assignment systems, resulting in reductions in walkout and ambulance diversion rates, and dramatic improvements in the department’s patient satisfaction scores — for which the department received an institutionwide Service Excellence Award. more

Research Summary

Dr. Hill is actively involved in many specialty interests, including protocol development to reduce hospital readmissions and improve emergency department operations, as well as characterization of emergency department observation unit population.

His research interests include the utilization, management and role of observation or acute care medicine in the practice of emergency medicine. Specifically, he is interested in the role this field can play in the interdisciplinary management of special disease process, such as asthma patients, low- to intermediate-risk chest pain patients, sickle cell disease patients and those with acute decompensated heart failure. In addition, Dr. Hill was involved in several projects examining the role and utility of novel devices designed to detect the presence of cardiac ischemia. He was the co-primary investigator on a multisite Food and Drug Administration approval trial of a magnetocardiography device that has shown promise as a very sensitive adjunct to the EKG in identifying patients with acute coronary syndrome.
