Stratton, S.J. and Tyler, R.D. (2006). Characteristics of Medical Surge Capacity Demand for Sudden-Impact Disasters. Academic Emergency Medicine 13(11):1193-7.
Using data from “established databases and published reports,” the authors examined both the baseline capacity of U.S. healthcare facilities and the length of time it took for external facilities to provide assistance after a no-notice critical incident. They concluded that communities should plan to maintain their provision of medical services without assistance for at least 24, and as much as 96 hours, after such an incident.
