The registry committee of Korean Society of Nephrology has collected data about dialysis in Korea through on-line registry program in KSN internet web site. The status of renal replacement therapy in Korea at the end of 2015 was as follows:
1) The total number of patients with renal replacement therapy (RRT) was 87,014(hemodialysis: HD 62,634, peritoneal dialysis: PD 7,352, functioning kidney transplant:KT 17,028). Prevalence of RRT was 1,689patients per million population(pmp). The proportion of RRT was HD 72%, PD 8%, and renal transplant 20%.
2) New RRT patients in 2015were 14,756(HD 12,011, PD 854, KT 1,891). Incidence rate was 286.4pmp in 2015.
3)The most common primary cause of end stage renal diseases was diabetic nephropathy (48.4%), hypertensive nephrosclerosis (20.2%)and chronic glomerulonephritis (8.5%), in order.
4)The number of RRT centers was 846and total number of HD machines was 22,750. Dialysis patients' individual data were collected from 67.1% of overall RRT centers.
5)Mean age of HD patient was 61.6yearsold, of PD was 55.7years old. Proportion of patients on HD more than 5 years' maintenance was 45%. Mean blood pressure was 99.6mmHg in HD and 98.2mmHg in PD patients. Pulse pressure was 65.9mmHg in HD and 53.6mmHg in PD patients. Mean hemoglobin of HD patient was 10.5 g/dL (hematocrit 31.8%), PD was 10.3g/dL. Mean urea reduction ratio was 69.3% in male HD patients and 75.3% in female HD patients. Mean single pool Kt/V was 1.434in male patient, 1.708in female patients.
7) Common causes of death were unknown cause or not uremia associated cardiac arrest (15.0%), uremia associated cardiac arrest (13.1%), sepsis (11.0%), pulmonary infection (8.9%) and myocardial infarction(8.0%) in 2015. Overall patient survival of male dialysis patient in 5 years was 60.4%, female patients was 63.3%. HD patient's 5 year survival was 61.8% and PD was 60.3%. Five year survival of diabetic dialysis patients was 53.0%, chronic glomerulonephritis patients 78.0%, hypertensive nephrosclerosis patients 69.8%, respectively.
8)Survey on rehabilitation status of dialysis patients showed that 22% of HD patients have full time job and 9% have part time job. 36% of PD patients have full time job, and 13% have part time job.
9)The number of kidney transplantation was 1,891(deceased donor 901) in 2015.
10) Survey onelderlydialysis patients showed that over 50% of elderly(over 65-year-old) patients had underlying diabetic nephropathy and 20.6%elderly patientshad hypertensive nephrosclerosis. About the vascular access, lower proportion of elderlyHD patients had native vessel arteriovenous fistula than young(under 65-year-old)HD patients (69% vs 80%). The serum creatinine level of elderlyHD patients was 7.74mg/dl but that of young HD patients was 10mg/dl, also phosphorus level was lower in elderlyHD patient, 4.3 and 5.3mg/dl, respectively. Although thesmallsurface area dialyzer were used for elderlyHD patients, the urea reduction ratio and Kt/V were better in elderlyHD patients than young patients. Prevalence of complication was much higher in elderlydialysis patients than in young dialysis patients, especially cardiac and infectious complications. |
