P1496TRENDS IN THE INCIDENCE AND PREVALENCE OF END-STAGE RENAL DISEASE PATIENTS WITH HEMODIALYSIS IN ENTIRE KOREAN POPULATION: A NATIONWIDE POPULATION-BASED STUDY

Abstract

Abstract Background and Aims Data on the epidemiology and temporal trends of end-stage renal disease (ESRD) with hemodialysis are not well established in the entire Korean population. We aimed to estimate the incidence and prevalence of ESRD with hemodialysis in Korea between 2002 and 2017. Method Using the National Health Insurance Service database, we analyzed entire Korean population from 2002 to 2017. Hemodialysis patients was identified by using rare incurable disease codes (V001) or prescription of medical fee code of hemodialysis (O7020, O7021). We only included patients who have been maintained hemodialysis more than 90 days from the date of dialysis initiation to exclude short-term dialysis due to acute kidney injury or patients who converted to peritoneal dialysis or kidney transplantation. Results During the 16-year follow-up, the number of hemodialysis patients in Korea has steadily increased from 11,251 in 2002 to 67,486 in 2017. The mean age of hemodialysis patients has gradually increased from 55.57±13.31 years in 2002 to 62.13±13.23 years in 2017. Overall, the number of men tended to be somewhat higher than that of women, and the proportion of men increased slightly from 55.56% in 2002 to 58.45% in 2017. The proportion of diabetic patients increased rapidly from 23.84% to 47.84%, and the percentage of hyperlipidemic patients rose from 18.9% to 86.7%, while the percentage of hypertensive patients did not show a significant increase. The number of incident hemodialysis patients increased significantly from 4,406 in 2003 to 12,134 in 2014 and then decreased to 8,090 in 2017. In the incident patients, the increase in the proportion of male patients and the increase in diabetes and hyperlipidemia were observed in similar manner with prevalent patients. Conclusion The incidence and prevalence of hemodialysis in Korea gradually increased from 2002 to 2017. The proportion of men, diabetes and hyperlipidemia among patients with hemodialysis also increased continuously. These findings may contribute as groundwork for epidemiological studies of hemodialysis in Korea.
