Objective: The 2015 Lancet Commission on Global Surgery highlighted a critical shortage of surgical care in low and middle-income countries (LMICs). Since then death and morbidity from surgical vascular disease in particular has grown in LMICs as life expectancy increases. Despite this, the role of surgical non-governmental organisations (s-NGOs) in addressing vascular surgical need in LMICs has not been characterised. Design: A cross-sectional survey of international s-NGOs operating in LMICs was conducted. Multiple search strategies were employed to engineer redundancy and increase sensitivity. Search strategies included literature review via PubMed and Google Scholar, a review of national charity registries, and searching independent NGO databases. NGOs were included if they demonstrated current activity and a commitment to delivering or expanding access to surgical care. Surgical specialties were identified and compared by frequency. Results: Of 1,242 organisation names identified, 398 unique s-NGOs met inclusion criteria. A plurality of s-NGOs provided multiple specialties (n = 120, 30.2%). The most common surgical specialties offered were ophthalmology (n = 98, 24.6%), paediatric surgery (n = 84, 21.1%) and plastic and reconstructive surgery (n = 77, 19.3%). The least commonly delivered specialty was vascular surgery (n = 5, 1.3%). Only two s-NGOs (the Global Vascular Companionship and the World Federation of Vascular Societies) were dedicated exclusively to vascular surgery. Conclusions: Vascular surgery remains critically underrepresented among international s-NGOs relative to other surgical specialties, despite a growing global burden of vascular disease in LMICs. Efforts to address this gap focus mainly on local capacity building and training rather than direct care provision as recommended by the Lancet Commission, though investment in global vascular surgery remains substantially lower than in other specialties.
