    Research Summary

    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.
