Hao N, et al. - Among patients who underwent long-term peritoneal dialysis (PD) at a single PD center in Taiwan, researchers assessed mortality over a 5-year period in relation to time-varying serum albumin levels. They retrospectively analyzed medical records from 2011 to 2015. In the first 2 years (2011–2012), the applied predictor variables were time-averaged albumin level and serum albumin reach rate (defined as the percentage of serum albumin measurements that reached ≥3.5 g/dL). In the subsequent 3 years (2013–2015), all-cause mortality was used as the outcome variable. In this study, a lower mortality rate was observed over a 5-year period in relation to higher serum albumin reach rates and higher time-averaged serum albumin levels among patients undergoing long-term PD.
