In Chicago, the rate of opioid-related overdose death was highest among non-Hispanic Black individuals with a rate of 39.3 per 100,000 individuals in 2017, while in Cook County as a whole, the 2017 rate of opioid-related overdose deaths was highest among non-Hispanic White individuals with a rate of 19.9 per 100,000 individuals. During the planning phase, Cook County Health (CCH) will work with its partners to solidify existing partnerships, expand data sharing between existing partners, bring new collaborators to the table, and focus on opportunities to engage at-risk individuals who are justice-involved in evidence-based substance use disorder care (including medication-assisted treatment [MAT]), overdose prevention and harm reduction services, and wrap-around services needed to effectively address substance use. In the implementation phase, partners will actualize strategies that take full advantage of the data amassed, eliminate redundant processes, and expand access to evidence-based services, and share protocols with community-based agencies to ensure sustainability. Data sources will include, but are not limited to, information from the Cook County Medical Examiner, Cook County Adult Probation Department, and Cook County Health.
