Abstract

as well as by the presence (detection of the drug in decedent) of co-occurring nonopioid drugs (cocaine, methamphetamine, and benzodiazepines). Three key findings emerged regarding changes in opioid deaths from July-December 2017 to January-June 2018. First, overall opioid deaths decreased 4.6%. Second, decreases occurred in prescription opioid deaths without co-involved illicit opioids and deaths involving non-IMF illicit synthetic opioids (fentanyl analogs and U-series drugs) (5). Third, IMF deaths, especially those with multiple illicit opioids and common nonopioids, increased. Consequently, IMF was involved in approximately two-thirds of opioid deaths during January-June 2018. Notably, during January-June 2018, 62.6% of all opioid deaths co-occurred with at least one common nonopioid drug. To maintain and accelerate reductions in opioid deaths, efforts to prevent IMF-involved deaths and address polysubstance misuse with opioids must be enhanced. Key interventions include broadening outreach to groups at high risk for IMF or fentanyl analog exposure and overdose. Improving linkage to and engagement in risk-reduction services and evidence-based treatment for persons with opioid and other substance use disorders with attention to polysubstance use or misuse is also needed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
