Understanding how medical students perceive global surgery will be essential in strengthening the global surgery workforce by 2030. This study investigated the knowledge, attitudes and exposure of Belgian medical students towards global surgery and identified avenues for medical institutions to include meaningful educational opportunities. An online survey was distributed to first to final year medical students across Belgian universities using social media. Data were collected on demographics, exposure, knowledge and attitudes towards global surgery. Odds ratios with 95% confidence intervals were calculated. A total of 304 medical students participated from four Belgian universities. A minority reported having exposure to global surgery (24.7%), and most wanted more exposure (75.3%). Almost all respondents agreed (94.4%) that it is a relevant topic for medical students, and most agreed (71%) more compulsory education on the topic is needed. Only 13 to 44% of students could correctly answer questions testing global surgery knowledge. Personal/family responsibilities were the most important barrier to pursuing global surgery careers. Global surgery knowledge and exposure is limited among Belgian medical students despite interest in the field. These results advocate for the inclusion of decolonised global surgery education alongside equitable international clinical internships in medical education worldwide.
