Use of preinjury antiplatelet and oral anticoagulant agents on outcomes following blunt trauma in an Asian population: a 1:2 propensity score matched study.

Background: Bleeding is a feared complication of antiplatelets (APTs) and oral anti-coagulants (OACs) use. Asians are at higher risk of bleeding from APT/OAC compared to Western population. Our study aims to investigate the impact of preinjury APT/OAC use on outcomes of moderate to severe blunt trauma.
