The Michigan Opioid Partnership (MOP) is a public-private collaborative focused on decreasing opioid overdoses and deaths in Michigan. The MOP includes the State of Michigan and key philanthropic organizations. Since its inception in 2018, the partnership has supported the implementation of medication for opioid use disorder (MOUD) programs in Michigan emergency departments (EDs) through grant funding and technical assistance. With changes in available funding occurring in 2024, the MOP was no longer able to provide grant support to hospitals. However, the MOP continued to offer technical assistance to EDs implementing MOUD programs and started exploring systems-level strategies to promote sustained statewide implementation.
