Legacy Drug Abuse Warning Network (DAWN 1992-2011)
Legacy DAWN (data collection through 2011) was a public health surveillance system that monitored emerging drug trends in both (1) emergency department visits in hospitals and (2) deaths reported by medical examiners and coroners (ME/C) across the Nation.
Legacy DAWN was a longitudinal probability sample of hospitals located throughout the United States, including Alaska and Hawaii. Non-Federal, short-stay, general surgical and medical hospitals located in the United States, with at least one 24-hour emergency department (ED) were eligible to participate. Data were collected from a representative sample of hospitals in the Nation and select metropolitan areas. The mortality component of Legacy DAWN did not rely on a statistical sample of ME/Cs.
