Emergency Department as the Entry Point to Inpatient Care: A Nationwide, Population-Based Study in South Korea, 2016–2018

Abstract: (1) Background: The emergency department provides lifesaving treatment and has become an entry point to hospital admission. The purpose of our study was to describe the characteristics and outcomes of patients who were admitted through the emergency department to the intensive care unit or general ward. (2) Methods: We performed a retrospective, cross-sectional, descriptive analysis using the National Emergency Department Information System, analyzing patient data including disease category, diagnosis, and mor… Show more

“…The baseline ED visit rate at our ED Center was 27,010 visits made by adult patients, from which 21.4% were hospitalized in 2018. Compared to international data, where the hospitalization rates at the ED have been found to vary, between 12.4–58% depending on the studied country, such as the US, South-Korea, or Australia [ 10 , 21 , 22 ], our hospitalization rate was somewhere between these values. The observed differences between the countries are most probably due to the differences in the healthcare systems, and the distinct patient-routes of treatment.…”

“…Data source and setting patient-related information were anonymized and checked for data integrity. In Korea, EDs are classi ed into three levels based on their capacity and capability: level 1, regional emergency centers; level 2, local emergency centers; and, level 3, local emergency facilities (17). Level 3 EDs have fewer capabilities than level 1 or level 2 EDs; as a result, the data received from level 3 EDs are limited.…”

“…We performed multivariate logistic regression analyses to model the effects of patient and hospital variables as predictors of prolonged EDLOS (both 6 h and 12 h) and in-hospital mortality. Since level 3 EDs may differ from level 1 or 2 EDs in ED settings, patient populations, and disease spectra [ 48 ], we conducted sensitivity analyses excluding patients from level 3 EDs using the same model. To evaluate the potential differential associations of hospital characteristics with prolonged EDLOS vs. in-hospital mortality, we performed stratified analyses with the highest hospital staffed bed category (1,000 or more) or type of ED (level 1) as the reference in the same logistic regression model.…”
