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.
