The Emergency Department Drug Surveillance (EDDS) system was initiated in Maryland, where it was piloted in seven Maryland hospitals (2017-2020). EDDS collaborates with hospitals to obtain both quarterly exports of ED patients’ de-identified hospital electronic health records (EHR) information and an annual sample of approximately 150 de-identified urine specimens.
In 2020, EDDS added five hospitals in California, Colorado, New Jersey, Oregon, and Utah, and in 2021-2022 CESAR is adding 20 more hospitals.
The University of Maryland’s Strategic Partnership: MPowering the State’s Opioid Use Disorders Initiative provided funding to pilot EDDS in Maryland (Maryland Pilot, 2017-2020). The Office of National Drug Control Policy (ONDCP) has provided funding to expand EDDS to hospitals outside of Maryland (Phase I and Phase II, 2020-2022).
