OBJECTIVES: This study sought to determine the rate of emergency department
use among the elderly and examined whether that use is reduced if the
patient has a principal-care physician. METHODS: The Health Care Financing
Administration's National Claims History File was used to study emergency
department use by Medicare patients older than 65 years in Washington State
during 1994. RESULTS: A total of 18.1% of patients had 1 or more emergency
department visits during the study year; the rate increased with age and
illness severity. Patients with principal-care physicians were much less
likely to use the emergency department for every category of disease
severity. After case mix, Medicaid eligibility, and rural/urban residence
were controlled for, the odds ratio for having any emergency department
visit was 0.47 for patients with a generalist principal-care physician and
0.58 for patients with a specialist principal-care physician. CONCLUSIONS:
The rate of emergency department use among the elderly is substantial, and
most visits are for serious medical problems. The presence of a continuous
relationship with a physician--regardless of specialty--may reduce
emergency department use.
