Background. Extracorporeal membrane oxygenation (ECMO) represents a valuable and rapidly evolving therapeutic option in patients with severe heart or lung failure following cardiovascular surgery. However, survival remains poor and accurate risk stratification challenging. We therefore evaluated the predictive value of urinary output (UO) within 24-hours after ECMO initiation on mortality in patients undergoing veno-arterial ECMO support following cardiovascular surgery and aimed to improve established risk prediction models

Methods and Results. We included 205 patients undergoing veno-arterial ECMO therapy following cardiovascular surgery at a university-affiliated tertiary care center into our single-centre registry. During a median follow-up time of 35 months (IQR 19- 69), 64% of patients died. 24-hour UO was the strongest predictor of outcome among renal function parameters with an ajdusted HR per 1-SD of 0.55 (95%CI 0.40- 0.76; P<0.001) for 30-day mortality and of 0.65 (95%CI 0.53- 0.86; P=0.002) for 2-year long-term mortality. Most remarkably, 24-hour UO showed additional prognostic value beyond that achievable with the SAPS-3 and SOFA score indicated by improvements in the category-free net reclassification index for 30-day mortality (SAPS-3: 36%; P=0.015; SOFA: 36%; P=0.02) as well as for 2-year mortality (SAPS-3: 33%; P=0.02; SOFA: 43%; P=0.005).

Conclusions. We identified 24-hour UO as a strong and easily available predictor of mortality in patients undergoing ECMO therapy following cardiovascular surgery. Implementation of 24-hour UO leads to a substantial improvement of established risk prediction models in this vulnerable patient population. These results are particularly compelling, because measurement of UO is inexpensive and routinely performed in all critical care units.
