IntroductionContinuous dialysis in hemodynamically stable patients with acute kidney injury (AKI) may impact outcomes differently than intermittent dialysis. We evaluated differences in patient and kidney outcomes between the two modalities.MethodsClinical and 30-day outcome data for inpatients with AKI who were hemodynamically stable and not on ventilation and who received intermittent hemodialysis (IHD) or continuous kidney replacement therapy (CKRT) in public hospitals in Kuwait from January 1 to December 31, 2021, were prospectively collected.ResultsWe recruited 229 patients (age: 59.9 years; males, 60.3%; baseline eGFR, 56 ml/min). CKRT accounted for 72.9% of cases due to lack of access to water treatment. No statistically significant differences were observed between groups in terms of age, baseline eGFR, sex, comorbidities, cause of AKI, or fluid administration. Intensive care unit contributed 21% of cases, with no significant difference between groups. More IHD patients received diuretics (62.9% vs. 43.1% for CKRT, p = 0.008). At 30 days, 21.8% of patients had died. There was no statistically significant difference in mortality between groups (16.1% for IHD vs. 24% for CKRT, p = 0.2). Final eGFR was 53.2 ml/min, with no difference between groups. Complete kidney recovery was greater with CKRT (33.1% vs. 13.5%, p = 0.009). Baseline eGFR < 60 ml/min did not influence mortality or kidney recovery.ConclusionCompared with IHD, CKRT did not lower mortality at 30 days, which is similar to that of randomized trials; however, it was associated with better complete kidney recovery, which was reported in observational studies.The Author(s).
