GlobalSurg is an international research collaboration in global surgery and global health. It was established to represent practising surgeons from around the world and support collaborative international research into surgical outcomes by fostering local, national and international research networks. In 2017, the National Institute of Health Research (NIHR) Unit on Global Surgery was formed, a consortium between the Universities of Birmingham, Edinburgh and Warwick, together with GlobalSurg international partners. Our growing network now includes over 5000 clinicians in more than 100 countries. The ethos is inclusive and collaborative: our international cohort studies are open to all collaborators, including medical students, clinical officers, doctors, nurses and researchers. We run annual research prioritisation events, allowing surgeons from all over world to contribute to the direction of the group. Our cohort studies aim to give grass-root surgeons the opportunity to participate in major projects. They are designed to ensure easy delivery by local surgeons and will not require extra resources or funding. Every researcher who contributes data into a cohort study will be a Pubmed-citable collaborator on study papers which will be published under one main name – GlobalSurg – to represent our group effort. See our publications page for more information. Our cohort studies are relevant, prospectively-run, and high quality. The also act to generate questions for future global research studies, including the opportunity for randomised trials.
