Abstract

Background
With the recent aging of the population, the transition to a disease structure centered on chronic diseases is accelerating. Moreover, the socio-economic gap and the polarization of the health gap between regions further increase the burden of disease on the country. Accordingly, this study calculated the disease cost of hypertension, diabetes, and hyperlipidemia, which are the three major chronic diseases, to establish an effective health promotion policy strategy for each region, and analyzed the gap in disease cost within the region to determine health determinants at the individual as well as the regional level.
Methods
This study utilized data from the 2015 sample cohort of the National Health Insurance Service and calculated the disease cost of patients (diabetes: I10–I15, hypertension: E10–E14, hyperlipidemia: E78) based on the main diagnosis.
Results
Based on our analysis, the case of medical use in cities and provinces was higher than in metropolitan cities, with relatively small medical use in Seoul and Gangwon-do. In terms of the disease cost, the cost of chronic diseases in Seoul and Jeju was the highest, but the difference in disease cost between patients in each region was the largest in Seoul and Gangwon-do.
Conclusion
The results of this study provide meaningful data for implementing efficient health promotion policies by analyzing the differences in disease cost and identifying health determinants in different regions. Furthermore, in Korea, where socioeconomic differences are clearly revealed, it can be used as a basis for preparing a strategic plan, from a long-term perspective, to improve the health of patients with chronic diseases in the future.
