The effect of multidisciplinary extracorporeal membrane oxygenation team on clinical outcomes in patients with severe acute respiratory failure

Abstract

BACKGROUND: The Extracorporeal Life Support Organization (ELSO) has suggested that extracorporeal membrane oxygenation (ECMO) patients should be managed by a multidisciplinary team. However, there are limited data on the impact of ECMO team on the outcomes of patients with severe acute respiratory failure. METHODS: All consecutive patients with severe acute respiratory failure who underwent ECMO for respiratory support from January 2012 through December 2016 were divided into the pre-ECMO team period (before January 2014, n = 70) and the post-ECMO team period (after January 2014, n = 46). Clinical characteristics and outcomes were compared between the two groups. RESULTS: The mortality rates in the intensive care unit (72.9 vs. 50.0%, P = 0.012) and hospital (75.7 vs. 52.2%, P = 0.009) were significantly decreased in the post-ECMO team period compared to the pre-ECMO team period. The median duration of ECMO support was not different between the two periods. However, the proportion of patients successfully weaned off ECMO was higher in the post-ECMO team period (42.9 vs. 65.2%, P = 0.018). During ECMO support, the incidence of cannula problems (32.9 vs. 15.2%, P = 0.034) and cardiovascular events (88.6 vs. 65.2%, P = 0.002) was reduced after implementation of the ECMO team. The 1-year mortality was significantly different between the pre-ECMO team and post-ECMO team periods (37.8 vs. 14.3%, P = 0.005). CONCLUSION: After implementing a multidisciplinary ECMO team, survival rate in patients treated with ECMO for severe acute respiratory failure was significantly improved.
