Abstract
Background and Aims
A growing number of patients suffers from End Stage Kidney Disease(ESKD), causing a logistical and economic burden to the healthcare system. Utilization of home dialysis is low in many countries worldwide, although home dialysis has several advantages including higher quality of life and possibly lower costs. The aim of this study is to explore time trends in the use of home dialysis in the Netherlands.
Method
Anonymized registry data from the Dutch Renal Registry (RENINE) were used for this study. All dialysis episodes of adult patients who started dialysis treatment between 1997 through 2016 in the Netherlands were included, including those who previously underwent kidney transplantation. Dialysis episodes shorter than 90 days were excluded. The probability of starting home dialysis between 1997 through 2016 was evaluated in time periods of 5 years, using logistic regression analysis. Home dialysis was defined as start with peritoneal dialysis or home haemodialysis, or transfer to either within 2 years after dialysis start. A logistic multilevel model was used to adjust for clustering at patient level. The cumulative incidence function of start of home dialysis in incident patients was estimated with a competing risk model with recovery of kidney function, kidney transplantations, and all-cause mortality as competing events. All analyses were stratified for age categories at dialysis start: 20-44 years, 45-64 years, 65-74 years and ≥75 years.
Results
A total of 33,340 dialysis episodes in 31,569 patients were evaluated. Between 1997 and 2016, mean age at start of dialysis treatment increased from 62.5±14.0 to 65.5±14.5 years in in-centre haemodialysis patients, whereas it increased from 51.9±15.1 to 62.5±14.6 years in home dialysis patients. In patients < 65 years, the probability of starting home dialysis was significantly lower during each 5-year period compared to the previous period, and kidney transplantation occurred more often. In patients ≥ 65 years, incidence of home dialysis remained constant, whereas mortality decreased.
Conclusion
In patients < 65 years, the overall probability of starting home dialysis declined consistently over the past 20 years. The age of home dialysis patients increased more rapidly than that of in-centre dialysis patients, implying that pre-dialysis education and organization of home dialysis must be adapted to the needs of the elderly patient. These developments have a significant impact on the organisation of home dialysis for patients with ESKD.
