Abstract

BACKGROUND AND AIM:

Data regarding health-care costs and utilization for inflammatory bowel disease (IBD) at the population level are limited in Asia. We aimed to investigate the nationwide prevalence and health-care cost and utilization of IBD in Korea.

METHODS:

We tracked the IBD-attributable health-care costs and utilization from 2010 to 2014 using the public dataset obtained from Korean National Health Insurance Service claims. We estimated the nationwide prevalence of IBD using population census data from Statistics Korea during the same period.

RESULTS:

In total, 236 106 IBD patients were analyzed. The estimated IBD prevalence significantly increased from 85.1/100 000 in 2010 to 106/100 000 in 2014. The overall annual health-care costs for IBD increased from $23.2 million (US dollars) in 2010 to $49.7 million in 2014 (P < 0.001). During the same period, the health-care cost per capita also increased from $572.3 to $983.7 (P < 0.001). The outpatient to total cost ratio increased from 45.5% in 2010 to 66.6% in 2014. Regarding health-care utilization, the outpatient to total days of service use ratio increased from 73.1% in 2010 to 76.9% in 2014. Of the total days of service used, the proportions of tertiary, general, and community hospitals increased significantly with a concomitant decrease in that of primary clinics (all P values < 0.001).

CONCLUSIONS:

This population-based study confirmed the steadily rising rate of prevalence of IBD in Korea. It also demonstrated that the shifting to outpatient care and advanced care settings are drivers for the dramatic increase in IBD-related health-care costs in Korea.
