| Popis: | Purpose Priority on waitlist urgency over post-transplant survival has decreased waitlist mortality with no appreciable change in short to mid-term survival. We sought to define the effects of increased pressure to transplant sicker candidates on PGD incidence and mortality as a leading indicator for long-term effects. Methods We used the multi-center prospective Lung Transplant Outcomes Group cohort study, designed to identify risk factors for PGD and mortality. Patients were enrolled from August 2011 to June 2018 at 10 centers. PGD was graded based on the 2016 PGD consensus ISHLT guidelines. Specifically, PGD was defined as grade 3 PGD (PaO2 /FiO2 ratio Results 1,528 subjects were enrolled with a 25.6% incidence of PGD overall. PGD incidence increased from 14.3% to 38.2% over the course of the study. From 2012 to 2018, the median LAS increased from 38.7 to 42.9 and the use of ECMO salvage increased from 5.7% to 20.9% (Fig.1a). PGD was associated with mortality overall (p=0.0001, Fig.1b). Bridging strategies were not associated with mortality (p=0.66); however, salvage ECMO for PGD was significantly associated with mortality (HR 2.1 [1.6; 2.8]; p Conclusion Severity of illness continues to rise in modern surgical practice paralleled by significant increases in PGD incidence. Bridging strategies have increased but appear safe. PGD is highly associated with mortality and is increasingly treated with salvage ECMO. Though early mortality associated with salvage strategies is low, 1-year survival is significantly reduced. Given the increase in use of salvage ECMO, further work is needed on evaluating 2016 PGD definition. |
