Background:
Up to 40% of trauma patients die during the first 24 hours after injury due to massive hemorrhage. In patients who survive this critical time period, no information is available on rates of delayed major bleeding or factors associated with delayed major bleeding.
Methods:
A retrospective chart review of 150 critically ill adult trauma patients was used to determine the incidence of delayed major bleeding events. Cox proportional hazards multivariate analysis was performed to assess for risk factors associated with delayed major bleeding events. The anticipated rate of delayed major bleeding events was 10%.
Results:
The incidence of delayed major bleeding in this cohort of critically ill trauma patients was 44%. Predictors that were statistically significantly associated with delayed major bleeding included: male gender, pre-injury use of the antiplatelet agents aspirin and/or clopidogrel, presence of intracranial bleeding, higher injury severity scores, requirement of massive transfusion, and low pH values. Use of anticoagulant prophylaxis was not associated with delayed major bleeding.
Conclusion:
The rate of delayed major bleeding was higher than estimated. Larger retrospective and prospective cohorts are needed to confirm these findings.
