Review Meta Analysis
A meta-analysis to determine the effect of anticoagulation on mortality in patients with blunt head trauma.
Patients on warfarin are increasingly common in an ageing population. Previously published case series and cohort studies have resulted in conflicting conclusions with regard to the risk of fatal intracranial haemorrhage. The aim of this study was to undertake a meta-analysis in order to compare the mortality rate of anticoagulated head injured patients against the mortality rate of head injured patients not on coumarin anticoagulation. ⋯ The results of this meta-analysis has shown that the cohort of patients who are anticoagulated and suffer blunt head trauma appear to have an increased risk of death compared to a similar cohort of head injured patients who are not anticoagulated.
