Association between ultrafiltration variability and clinical outcomes in patients undergoing hemodialysis.

ABSTRACT: Our study seeks to access the impact of ultrafiltration volume (UFV) variability on clinical outcomes in patients undergoing maintenance hemodialysis (HD) using a population-based cohort. This study employed a retrospective design using data derived from the national HD quality assessment initiative in Republic of Korea, which was combined with health insurance claims records (n = 50,583). To assess UFV variability, a linear regression model was fitted for each individual across the six measurements, and the residual standard deviation from this model was calculated. Based on this metric, patients were stratified into four quartiles representing increasing levels of UFV variability (Q1 to Q4). The 5-year survival rates for patients in Q1, Q2, Q3, and Q4 were 68.3%, 67.9%, 66.4%, and
