Archived HotSpot Reports

NDEWS was first funded by the National Institute on Drug Abuse (NIDA) in 2014 as an expansion of its longstanding Community Epidemiology Workgroup (CEWG). Through July 2020, the first iteration of this system was overseen by researchers at the University of Maryland Center for Substance Abuse Research (CESAR). Their HotSpot reports from 2016 and 2019 are archived below.

NDEWS conducted on-the-ground epidemiologic investigations on topics of an immediate crisis or need and provided functional feedback to impacted communities to optimize current and future response. A minimum of five investigations were conducted over five years, prompted by trends in data from our indicators, NIDA, and/or local, regional, or state paired with anecdotal data.

HotSpot analyses was conducted with geocoding to pinpoint where use occurred and where overdose or other serious outcomes occurred. Users, caregivers, health care professionals, police, and other first responders were interviewed over several days in urban, rural, and suburban areas adjacent to the affected zip-codes.
