Kuo G, Chen SW, Fan PC, et al. - In this retrospective population-based cohort study, researchers evaluated all-cause mortality, end-stage renal disease (ESRD) , ventilator dependency, and readmission rate in correlation with duration of continuous renal replacement therapy (CRRT) received among patients who received extracorporeal membrane oxygenation (ECMO) and CRRT. They used Taiwan National Health Insurance Research Database from January 1, 2007 to December 31, 2013. This study included 247, 134 and 187 patients who survived the hospitalization in the CRRT for ≤ 3 days, 4–6 days and > 7 days respectively. Among ECMO patients who underwent CRRT for ≥ 7 days, they found similar long-term survival but increased ESRD and ventilator dependency. In addition, a higher readmission rate was noted in the CRRT ≥ 7 days group vs the 4–6 days and ≤ 3 days groups.
