title: Patient population and factors determining length of stay in adult ED of a Turkish University Medical Center.
abstract: This study is designed to analyze retrospectively patients who present to adult emergency department (ED) from January 1, 2002, to February 28, 2002. Age, sex, presentation time to ED, length of stay in emergency service, consultations, the number of patients who need to be hospitalized and also the number of hospitalized patients, diagnosis categories, and discharge instructions are analyzed. It is found that patients in most admissions are at 21 to 25 years of age. At night, the number of visits is decreased. Hospitalizations could be done to only about half of patients who in fact should be hospitalized. There is a correlation between the length of stay of patients in emergency service and the number of consultations per patient. There is also a correlation between patient complexity and length of stay in emergency service. The ED overcrowding rises with increased visits and patients staying in ED who should be hospitalized.
