Figures Are Even Higher For Minorities and Women
In the first study to quantify the contribution of emergency department care to overall U.S. health care, researchers at the University of Maryland School of Medicine (UMSOM) have found that nearly half of all US hospital-associated medical care is delivered by emergency departments. The paper highlights the major role played by emergency care in health care in the U.S. In recent years, the percentage of care delivered by emergency departments has grown significantly.
“I was stunned by the results. This really helps us better understand health care in this country. This research underscores the fact that emergency departments are critical to our nation’s healthcare delivery system.” said David Marcozzi, MD, MHS-CL, FACEP, an associate professor in the UMSOM Department of Emergency Medicine, and co-director of the UMSOM Program in Health Disparities and Population Health. “Patients seek care in emergency departments for many reasons. The data might suggest that emergency care provides the type of care that individuals actually want or need, 24 hours a day.”
Although he now focuses on population health, Dr. Marcozzi is an emergency medicine faculty physician himself, and works one or two days a week in the University of Maryland Medical Center emergency department, treating patients.
This is the first study to quantify the contribution of emergency department care to overall U.S. hospital-associated health care. The paper appears in the latest issue of International Journal for Health Services.
For this study, Dr. Marcozzi and his colleagues examined publicly available data from several national healthcare databases, which covered all 50 states and the District of Columbia. They studied the period between 1996 and 2010.
For 2010, the most recent year examined, the study found that there were nearly 130 million emergency department visits, compared with almost 101 million outpatient visits and nearly 39 million inpatient visits. Inpatient visits typically involve a hospital stay, but are planned ahead, as opposed to emergency department visits, which are generally at least somewhat unexpected.
Over the 14-year period of the study, more than 3.5 billion health care contacts associated with hospitals – emergency department visits, outpatient visits, and hospital admissions took place. Over that time, emergency care visits increased by nearly 44 percent. Outpatient visits accounted for nearly 38 percent of contacts. Inpatient care accounted for almost 15 percent of visits.
