[17] . Basic pre-hospital services may reduce trauma mortality by 15% -- 20% [18] , [19] . There is no strong evidence to support a singular educational or clinical approach to first aid in low-resource environments [20] . Compelling studies have demonstrated benefits arising from LSFA programs in remote and underserviced settings ( Box 1 ). Box 1. LSFA in Remote and Underserviced Settings Ghana: Tiska et al. report on a first aid course for truck drivers in a low-resource setting with elevated rates of motor-vehicle trauma. The course emphasized airway management and external hemorrhage control, and improved the pre-hospital provision of first aid [25] . Uganda: Jayaraman et al. report on a program to provide over 300 police officers, taxi drivers, and community leaders with a 1-day first aid course. Six months following the course, 97% of participants had used at least one skill learned in the course, and there was evidence of knowledge retention [28] . The Community and Setting Sachigo Lake First Nation (population 400) is a remote community in northern Canada ( Figure 1 ). Similar to more than a hundred communities across Canada, Sachigo Lake is accessible only by air or seasonal ice roads. Full-time nurses and community health workers staff the local nursing station, funded by the Canadian government. A family physician visits the community for 2 -- 3 days per month. Hospital care is provided hundreds of kilometres away, with transport times seldom less than 4 hours. Community members hunt, fish, and trap
