Indication for ECMO predicts time to first actionable bleeding complication.

Purpose: Bleeding is a major complication of patients requiring extracorporeal membrane oxygenation (ECMO). Several risk factors have been identified; however, there remains a paucity of evidence for optimal management of anticoagulation and bleeding in ECMO patients.

Methods: A total of 255 patients required ECMO from January 1996 to December 2021 at a single institution.
