Abstract BACKGROUND AND AIMS Until 2019, in Uzbekistan, disposable dialyzers for dialysis were reused several times due to underfunding of the system. But in 2018, the President of the Republic of Uzbekistan Shavkat Mirziyoyev signed a decree on improving the nephrological and dialysis services in the country. After that, there is a sharp increase in funding and attention to the provision of hemodialysis care to the population of our country. Thanks to this Resolution, since 2019, in all regions of Uzbekistan, only disposable dialyzers are used for hemodialysis. To prospectively study the negative impact of the reusable use of disposable dialyzers on dialysis patients in Uzbekistan. METHOD The study took place in three dialysis centers in the country at different levels. Our observation of 165 (90 men and 75 women) patients took place for 2 years: from the beginning of 2018 to the end of 2019. The average age of the patients was 49.7 ± 14.1 years. During the first 12 months (before the release of the decree of the President of the Republic and funding), dialysis patients underwent multiple uses of dialyzers. The next 12 months were completely switched to single use. The average age of the patients was 48.1 ± 14.3 years. The average duration of hemodialysis was 37 (6–252) months. Survival was assessed using the Kaplan–Meier method. The confidence interval was determined by Greenwood. RESULTS During the 24 months of observation, out of 165 patients, 29.1% (n = 48) patients died, 70.9% (n = 117) survived (of which 11 patients underwent Tx). During 1 year of follow-up (the period of repeated use of disposable dialyzers), 21.2% (n = 35) patients died, 78.8% (n = 130) survived and continued to receive hemodialysis (6 patients Tx). A total of 68.6% (n = 24) of patients died from cardiovascular complications. The survival rate for 1 year (miltiple use period) was S(t) = 0.796 [95% confidence interval (95% CI) 0.736–0.856]. Over the next 12 months (single use period), out of 124 patients continuing to receive hemodialysis, 10.5% (n = 13) patients died, 89.5% (n = 111) patients survived (5 patients Tx). A total of 53.8% (n = 7) of these deceased patients died from CVD. The survival rate at the second year (single use period) was S(t) = 0.894 [95% CI 0.839–0.948]. CONCLUSION Compliance with the standards for hemodialysis, in particular, the single use of disposable dialyzers for hemodialysis sessions, leads to a decrease in the lethality of dialysis patients. The transition from multiple to single use of disposable dialyzers in one dialysis center in Uzbekistan showed a significant increase in survival of 12.3%.
