??? About DAWN
The Drug Abuse Warning Network (DAWN) is a national surveillance system that monitors drugrelated morbidity and mortality. Section 505 of the Public Health Service Act assigns this responsibility to the Substance Abuse and Mental Health Services Administration (SAMHSA), an agency of the U.S. Department of Health and Human Services. The Act requires SAMHSA to report annually on drugrelated visits to hospital emergency departments and on drugrelated deaths reviewed by medical examiners and coroners. SAMHSA has a contract with Westat, a private research firm based in Rockville, MD, to operate the DAWN system. DAWN collects data from a scientific sample of hospital emergency departments and a set of medical examiners and coroners from across the U.S., with concentrations in selected metropolitan areas. Each participating facility has a DAWN Reporter who is specially trained to identify DAWN cases by retrospectively reviewing emergency department medical records or death investigation case files. No patient, family member, or physician is ever interviewed. No direct identifiers for individual patients or decedents are collected. Beginning in 2003, DAWN cases include any emergency department visit or death that was related to drug use. Reportable cases include drug abuse, misuse, overmedication, accidental and malicious poisonings, and adverse drug reactions. For each case, the DAWN Reporter submits a case report detailing the specific drugs involved, and characteristics of the patient or decedent and event (visit or death). Patient and decedent characteristics include demographics (age, gender, race/ethnicity) and ZIP code. Other data items include date/time, chief complaint, diagnoses, and disposition for each emergency department visit; and date, cause, manner, and place of death for each decedent.
