When an earthquake struck Haiti, medical volunteers from around the globe flew in to try and help. Many arrived having worked in crisis zones before, others had received training in disaster medicine. But it appears that a number of well-intentioned medical volunteers arrived in Haiti having never worked outside their home countries. They had no training in disaster medicine nor experience working in so-called "low resource" settings. This caused problems. In our next installment of Tiny Spark, we look at the challenges medical volunteers faced in Haiti, the repercussions of poor medical decisions, and what the medical community is doing now to promote disaster training so that volunteers are better prepared the next time crisis strikes.
