Outcomes of Nontransfusable and Transfusable Patients After Major Noncardiac Surgery: A Retrospective Cohort Study

Anesth AnalgPublished Retrospective cohort study

Authors' conclusion

Our primary and secondary analyses demonstrate addressing anemia and minimizing or avoiding transfusion is associated with improved outcomes.

Study context

Population
Adult major noncardiac surgical admissions to 2 German hospitals (HELIOS Klinikum Gotha and Erfurt), 2008–2020
Participants
25,979 admissions
Exposure
Transfusion-free blood management (nontransfusable) vs transfusable patients; secondarily patient blood management (PBM) vs no PBM among transfusable patients
Outcome
Outcomes of nontransfusable (transfusion-free) vs transfusable adults undergoing major surgery
