Abstract
This research developed a model that predicts the congestion of the emergency room in real time based on the 2017 data of 414 emergency medical institutions nationwide. In the development of the predictive model, data mining techniques such as multiple linear regression analysis, subset selection, ridge regression, Lasso and principal component regression were applied, and principal component regression method showed high prediction power. The predictive power of the subdivided prediction models (especially regional emergency medical center (97.37%)) according to the types of emergency medical institution was higher than that of the predictive model based on the entire emergency medical institutions (92.73%). The emergency room congestion predictive model developed in this research can be used as basic data to solve the problem of overcrowding of emergency room and form a regional network between the emergency rooms.
