End-stage kidney disease in Brunei Darussalam (2011-2020).

INTRODUCTION: The Brunei Dialysis and Transplant Registry (BDTR) recorded data on patients with end-stage kidney disease (ESKD) from 2011 to 2020, mainly for planning of services and benchmarking of standards. We report the trends of epidemiologic and performance parameters, compare performances between modalities of Kidney Replacement Therapy and evaluate the survival of ESKD patients over the 10-year period. MATERIALS AND METHODS: Three groups of data were analysed from the BDTR over the 10-year period. Epidemiological data, blood parameters and dialysis are key performance indicators. RESULTS: There are increments in prevalence and incidence of treated ESKD patients in Brunei over 10 years, especially with haemodialysis (HD). The projected prevalence and incidence showed an anticipated annual increase of 42.2 per million population (pmp) and 9.9 pmp respectively. Diabetes mellitus (DM) (79%) was the main cause of ESKD. HD (86%), peritoneal dialysis (PD) (9%) and transplant (5%) were the main modalities of kidney replacement therapy in 2020. Cumulative results over the decade showed significant improvements in serum phosphate, peritonitis rates and HD blood flow rates. PD patients have better survival rates, lower systolic blood pressure and better adequacy. PD survival (patient survival of 91%, 73% and 56% at 1, 3 and 5 years respectively) was superior to HD survival (86% and 64% at 1 and 2 years, respectively), but patient demographics (age and DM status) were different. The 2020 dataset showed satisfactory anaemia management but mineral bone disease management was sub-optimal. Seventy percent of prevalent HD patients had arteriovenous fistula access. Thirty-two percent and fifty-two percent of HD and PD patients, respectively, achieved target dialysis adequacy. Peritonitis rate was 0.3 episodes per patient year. CONCLUSION: Brunei has a high incidence and prevalence of treated ESKD in the last decade, especially DM-related ESKD. This study has identified many specific areas to be targeted for improvements and provided evidence for further proliferation of PD and transplant preference policy.

Barriers to Kidney Transplantation as a Choice of Renal Replacement Therapy.

Brunei Darussalam has a live related kidney transplant program since 2013. Uptake of transplant remains poor in the country despite full government subsidy for health care. This study aims to assess barriers and factors affecting patients' preference toward dialysis over transplant as their choice of renal replacement therapy. It is hoped that the study can provide a better insight into the poor uptake of transplant in the country. METHODS: The target population was all patients with end-stage renal disease undergoing dialysis in Brunei Darussalam who are fit enough to undergo kidney transplant. The shortlisted patients were approached during their hemodialysis sessions or while waiting for clinical reviews in peritoneal dialysis clinics and were given self-administered structured questionnaires. RESULTS: Out of 348 eligible patients in the country, 226 (64.9%) agreed to participate in the study. The majority of patients (71.2%), especially the unmarried patients (81.5%), cited "lack of donor" as their main reason for not choosing transplant. "Happy with dialysis" (31.9%), "inadequate information" (21.2%), "unwilling to take risk" (26.5%), and "financial problems" (18.1%) were the other common factors identified. A total of 51.8% of the respondents had considered transplant, and 42.5 % of patients had considered the option of commercialization through foreign black market channels. Younger patients (<40 years) on dialysis for less than 5 years with higher education were more likely to consider transplant (P < .05). Likewise, patients who were younger, highly educated, and employed were more likely to choose commercialization (P < .05). CONCLUSION: Lack of donor and poor knowledge were the main barriers to patients receiving kidney transplant in the country. Religio-cultural barriers, lack of reimbursement, poor knowledge, and stringent donor criteria contributed to the limited donor pool. Despite universal health coverage for the population, financial and social security factors were still important determinants that influenced recipients' and donors' decisions to reject transplant.
