Objective: This study is to evaluate the difference in area of patients`` residence and the location of hospital admitted for acute myocardial infarction (AMI) patients and to delineate the factors related to using hospitals in different areas.
Methods: We used the 2012 Patient Investigation Data. The study subjects were patients whose primary diagnosis were AMI (ICD-10 I21, I22), admitted through the emergency department, aged above 40, and whose admission duration was less than 90 days. According to whether the patients chose hospitals in the same city or province(do) where they resided or different city or province(do), patient-related factors (age, sex, Charlson comorbidity index(CCI), area of residence) and hospital-related factors (hospital classification, number of beds, founder, hospital location,) were evaluated.
Results: 19.2% of AMI patients were admitted to hospitals in different city or province(do). Age, sex, or CCI were not related to using hospitals in different area. The use of hospitals in different area was more frequent in patients residing in province(do) than Seoul (OR, 17.414, 95% CI, 8.936~33.935). However, residing in metropolitan area was rather related to using hospitals in same area (0.317, 0.136~0.738). When moving to different area for medical care, there was a tendency to choose territory hospitals than general hospitals P=0.052), and the metropolitan cities`` hospitals than Seoul``s (2.515, 1.246~5.077).
Conclusion: Whereas residents of Seoul and Metropolitan city area mostly chose hospitals in the area of their residence for acute myocardial infarction treatment, 25% of residents of Province (do) area visited near-by larger hospitals in metropolitan city areas or Seoul for treatments. In case of emergency diseases, the urgency of the disease, as well as hospital-related factors, contributes to the choice of hospital.
