Inability to predict subprophylactic anti-factor Xa levels in trauma patients receiving early low-molecular-weight heparin

BACKGROUNDStandard low-molecular-weight heparin dosing may be suboptimal for venous thromboembolism prophylaxis. We aimed to identify independent predictors of subprophylactic Xa (subXa) levels in trauma patients treated under a novel early chemoprophylaxis algorithm.METHODSA retrospective analysis
