Sociodemographic and Economic Correlates of Dialysis Vintage in a Resource Challenged Setting: A Four-Year Prospective Study in Southwest Nigeria

Abstract

Background: : This was a 4-year prospective, observational study. The data was collected from the dialysis and medical records, both had the contacts of patients and relatives. Results: In a month, only 23.57% of the participants received the minimum prescribed twelve sessions, and 24.84% received the required erythropoietin dose. The mean dialysis vintage for all population was 9.13 ± 3.15 months, it was shorter for participants with hospitalization, (p<0.001), dialysis termination (p<0.001), intradialytic hypotension (p<0.001), and hypertension (p<0.001), Approximately, 14.2% of the participants had health insurance coverage, more so with the men After dialysis initiation, 6.69% of the participants were alive to the fourth year. The predictors of dialysis vintage were income (OR-4.62, 95% CI-2.88-6.24), health insurance (OR-8.11, 95% CI-4.82-13.35), dialysis duration (OR-6.38, 95% CI-2.40-9.55) and spKt/V (OR-4.24, 95% CI-0.48-5.91). Conclusion: Dialysis vintage was short (9.13 ± 3.15 months), more so in females, poor funding, peridialysis complications, and without health insurance. More concerted efforts from governments, multinational donor agencies, and philanthropists are needed in health insurance coverage, particularly for kidney care to increase the dialysis vintage.
