Global Outcomes After Laparotomy for Trauma

The goal of this observational study is to assessing the global variation in patient characteristics, management, and outcomes in those undergoing trauma laparotomy. The main questions it aims to answer are: * What are the post-operative mortality rates for patients undergoing a trauma laparotomy globally * What are the epidemiological characteristics (demographics, injury characteristics, baseline clinical characteristics, and surgical case mix) for patients undergoing a trauma laparotomy * What are the pre-operative, peri-operative, and post-operative processes of care for patients undergoing a trauma laparotomy This is a purely observational study on patients undergoing trauma laparotomy, with no direct change to clinical care.
