Since the end of the Cold War, Foreign Field Hospitals (FFHs) have been considered as a feasible solution to cope with the lack of prompt emergency aid in low-income countries, especially after sudden-onset events. The World Health Organization (WHO) and the Pan American Health Organization (PAHO) have developed guidelines regarding the dispatch of FFHs in areas after being hit by natural disasters. It has been demonstrated that the first hours after a catastrophic event are crucial in order to save lives. Therefore, coordination among organizations providing aid and high-level staff qualification must be guaranteed for the purpose of assuring the most cost effective management.
