Purpose: To identify socio-demographic factors in cataract surgery in Korea and expect future effect of the bundle of service system.
Methods: We analyzed the number of people undergoing cataract surgery and associated factors such as surgery ratio, region, age, income, and insurance status of 28,980 patients older than 40 years using data from the fifth Korea National Health and Nutrition Examination Survey 2008-2012 (KNHANES).
Results: Among total population in 2012, 47.5% of elderly aged 80 years and older have received cataract surgery. According to region in patients older than 40, Jeollanam-do showed the highest proportion of patients undergoing cataract surgery, at 12%, Daejeon showed the lowest proportion of 3.6%, and Seoul showed 6.8%. Regional analysis was also performed by analyzing the number of cataract patients per ophthalmologist. Jeollanam-do showed the highest with 40,115 patients per ophthalmologist, and Seoul showed the least with 1,094 patients per ophthalmologist. The sociodemographic factors such as education or income, were not associated with cataract surgery after adjusting for age and regional difference. On the other hand, subjects with medicaid were associated with 1.6-fold (95% confidence interval, 1.3-2.0) higher rate of cataract surgery than subjects with national health insurance.
Conclusions: Regional disparity was found in the cataract surgery rate and surgery rate per an ophthalmologists, whereas sociodemographic factors were not significant in receiving benefits of cataract surgery. Before the amount of bundled payment is changing, down-leveling of quality of care and deepening of disparities among health care provider should be considered.
