A FOUR-YEAR ANALYSIS ON HOME DIALYSIS AT THE NORTH BRISTOL NHS TRUST-WHAT TO DO NEXT?
Nephrology Dialysis Transplantation(2022)
Abstract
Abstract BACKGROUND AND AIMS Home dialysis, including peritoneal dialysis (PD) and home hemodialysis (HHD), has been associated with improved patient autonomy, quality of life and overall cost effectiveness (Weinhandl et al. Propensity matched mortality comparison of incident hemodialysis and peritoneal dialysis patients. J Am Soc Nephrol. 2010; 21: 499–506). The 2021 Get It Right First Time (GIRFT) Renal report revealed that home dialysis patients were at a lower risk of contracting and dying of coronavirus disease 2019 (COVID-19), compared to those who received in-center hemodialysis (ICHD) (2). Despite these advantages, uptake of home dialysis is still lower than that of ICHD. The aim of our study was to analyse the numbers and reasons for home dialysis withdrawal at the North Bristol NHS Trust between 2018 and 2021. METHOD All patients on PD and HHD between 2018 and 2021 were included. Analysis of the episodes that led to home dialysis cessation was carried out. As some patients required withdrawal more than once during the 4-year period, each episode of dropout was considered separately. The prevalence rate of patients on home dialysis was calculated. RESULTS The total number of patients on home dialysis increased from 74 in 2018 to 98 in 2021. The male: female ratio of patients was 3:2 with an average age of 58.3. The number of patients on PD increased from 58 at the end of 2018 to 82 in 2021. The number of patients on HHD remained stable over the years, with an average of 16. The prevalence rate of home dialysis was 17.1% at the end of 2021. Figure 1 shows the total number of patients who started and dropped out of home dialysis every year. The number of patients initiating PD was 58 in 2018, 55 in 2019, 37 in 2020 and 59 in 2021. The number of dropouts was 57 in 2018, 41 in 2019, 29 in 2020 and 43 in 2021. The dip in number of patients initiated on PD in 2020 can be attributed to the start of the COVID-19 pandemic, when elective procedures were temporarily withheld. On the other hand, a lower number dropped out during 2020. This may be explained by the emphasis given to self-isolation rules and persistence with home dialysis during the outbreak. The overall increase in PD uptake in 2021 may be explained by the establishment of a new specialist clinic that promotes the uptake of home dialysis. The initiation of a new peer support service group in 2021 may also have contributed. The number of patients initiating and withdrawing from HHD followed the same pattern, with a significant dip in 2020. Figure 2 demonstrates the reasons for withdrawal from PD over the study period. The most prevalent reasons were PD-related infections and transplantation. The observed figures for transplantation reflect the continuous efforts involved in the maintenance of a successful transplant programme. The figure also shows that termination of PD due to failure was highest in 2021. The authors postulate that this surge might be due to the previous year's low PD dropout rate. The leading reason for stopping HHD was transplantation. Other reasons included recovery of renal function and switching to conservative management. Death led to one dropout/year in 2018–20, but none in 2021. CONCLUSION Around 17% of the NBT’s total dialysis population is currently on home dialysis. The commonest reasons for termination of home dialysis were transplantation and PD-related infections. The GIRFT report recommends that all adult renal units in the UK should reach a minimum prevalence rate of 20% of their dialysis population on home dialysis by the end of 2024 (Lipkin et al. Renal medicine: Get It Right First Time (GIRFT) Programme National Specialty Report. March 2021. NHS England and NHS Improvement). Whereas our statistic falls slightly short of this, we aim to reach this target through various strategies. These include continued audit, home dialysis campaign, continued psychological services and a reduction in waiting time for PD catheter insertion.
