Trauma accounts for approximately 9% of all global deaths, more than malaria, HIV, and tuberculosis combined. 1 It disproportionately affects individuals of working age, with concurrent high disability and mortality rates that result in wide-ranging economic impacts. Paradoxically, resource-poor areas have the highest rates of trauma but also have the worst outcomes. Consequently, there is a strong argument for optimizing trauma care in these regions, in terms of both health and economic outcomes.In managing abdominal trauma, the laparotomy remains a key procedure worldwide, providing life-saving intervention in cases where there is evidence of uncontrolled hemorrhage or a hollow viscus perforation. The laparotomy has previously been defined as a "Bellwether" procedure, as a marker of a surgical system's ability to provide safe-surgical care. 2 However, patient-level data for those undergoing a trauma laparotomy globally is currently limited. Using the trauma laparotomy as a surrogate marker for the ability of a health system to deliver trauma care provides an opportunity to better understand the need for trauma systems development worldwide.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
