Solving the "last mile" problem in overdose prevention: Lessons from the HEALing Communities Study.

The concept of the "last mile," crucial in logistics for its complexity and cost, has a parallel in public health services. The last mile in public health is fraught with issues such as fragmented services, regulatory barriers, and resistance to evidence-based interventions. This commentary draws parallels between the challenges in delivering goods to consumers' doorsteps and the difficulties in delivering interventions to reduce overdoses in the community. The HEALing Communities Study (HCS), a large implementation science research study, provides an example of how to navigate some of these last-mile challenges. HCS used a community-driven process that considered local characteristics and preferences, and engaged people with lived experience to create effective and sustainable solutions. However, the study also encountered significant challenges in building a delivery infrastructure, working with delayed and incomplete data, and overcoming stigma around substance use interventions. Lessons from the logistics sector can help improve the efficiency and equity of overdose prevention efforts, ensuring that people receive the life-saving interventions they need.
