Drug Abuse Warning Network

Alternate Titles(s): Legacy DAWN Data
UID: 10024
The Drug Abuse Warning Network (DAWN) is a nationally representative public health surveillance system overseen by the Substance Abuse and Mental Health Services Administration (SAMHSA) that continuously monitors drug-related visits to hospital emergency departments (EDs). A DAWN case is any ED visit where recent drug use is a direct or contributing factor for the ED visit. The dataset includes information obtained from medical records, including patient demographics, a list of up to 16 drugs involved in the ED visit, toxicology confirmation, route of administration, type of case, and disposition of the patient following the visit. For patient confidentiality, primary sampling units (PSUs) and strata identification values are randomized each year. "Legacy" DAWN datasets contain data collected between 1992 and 2011. The DAWN surveillance system was re-established in 2018 and resumed data collection.
