Emergency Department Substance Use Surveillance System

or lock-up, parolees or probationers, and drug court participants. A similar methodology is promising for use in other venues, such as in trauma units and emergency departments, where biological samples are often collected from patients. Before the specimens are discarded, the project will re-test them for an expanded panel of drugs, including fentanyl and methamphetamine, to determine what old and new illicit drugs are detected or missed by conventional testing protocols, and how the drug patterns might vary by subpopulation and geography. Bypassing the expense of collecting the original specimens and re-using those that have already been tested with known results yields a relatively inexpensive and timely picture of emerging drugs in a given subpopulation and locality. Supplemental validation of testing gaps, needs, and positivity trends against other data sources, such as de-identified electronic health records from patients treated in the hospital care setting is also desired. ONDCP is seeking to apply this testing methodology and insight from supplemental analyses to Emergency Department populations in locations throughout the United States to reinforce best practice guidelines, testing standardization, and build local and national surveillance capacity.
