Dr. Hill 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.  In addition, he is 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 new 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 walk-out and ambulance diversion rates, and dramatic improvements in the department’s patient satisfaction scores; for which the department received an institution wide award for Service Excellence. Dr. Hill also participates in the JH faculty mentoring program with three mentees; Dr. Kamna Balhara, Dr. Timothy Chang, Dr. Susan Peterson.

Research Interests

Dr. Hill is actively involved in many specialty interests including chest pain and CHF protocol development to reduce hospital readmissions, as well as characterization of ED 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 anemia patients, and those with acute decompensated heart failure.  In addition, he is actively involved in several projects examining the role and utility of novel devices designed to detect the presence of cardiac ischemia.  Dr. Hill was the Co-PI on a multi-site, FDA-approval trial of a magnetocardiography device that has shown promise as a very sensitive adjunct to the ECG in identifying patients with ACS. 


Over the past five years Dr. Hill has been published many times in nationally recognized publications such as Academy of Emergency Medicine, American Journal of Emergency Medicine and Annals of Emergency Medicine. He has lectured internationally and has written text book chapters on the topic of risk stratification of the undifferentiated chest pain patient.
