목적 : To evaluate the incidence and risk factors of acute postoperative endophthalmitis (POE) after cataract surgery from 2011 to 2015 in Korea.
방법 : A nationwide retrospective cohort study was performed by using claims data from the Korean National Health Insurance Service (KNHIS) database collected during 2011-2015. Cataract surgery and acute POE were identified using Korean Electronic Data Interchange (KEDI) code and Korean Classification of Diseases (KCD)-7 code.
결과 : A total of 2,236,107 eyes in 1,591,176 patients underwent cataract surgery from 2011 to 2015 in Korea. The incidence of acute POE after cataract surgery was 0.09% and remained stable during 5 years. 2,041 eyes experienced acute POE after 8.46±10.18 days after cataract surgery. In multivariate analysis, intraoperative posterior capsule rupture, male gender and preoperative diabetes were associated with a higher risk of acute POE. Living in rural area, low household income and surgery in tertiary healthcare centers were socioeconomic factors associated with higher risk of acute POE.
결론 : The incidence of acute POE after cataract surgery in Korea remained unchanged during 5-year study period. Intraoperative posterior capsule rupture, male gender, preoperative diabetes, low household income and surgery in tertiary healthcare centers were associated with higher risk.
