The Drug Abuse Warning Network (DAWN) is a nationwide public health surveillance system administered by SAMHSA. Data are abstracted directly from hospital electronic health records, which includes data on ED visits related to recent substance use and misuse, such as alcohol use, illicit drug use, suicide attempts, and nonmedical use of pharmaceuticals. Data are gathered from 49 hospitals, including sentinel hospitals in addition to probability-sampled hospitals.
