Examining Changes in Coalition Dynamics to Support Opioid Fatality Reduction.

Area of Science:

• Public Health
• Health Services Research
• Community Health

Background:

• Opioid-related fatalities remain a significant public health crisis.
• Effective interventions, such as overdose education and naloxone distribution (OEND), are crucial for harm reduction.
• Community coalitions play a key role in the implementation and scaling of public health initiatives.

Purpose of the Study:

• To examine the relationship between changes in coalition capacity and leadership and the adoption and reach of OEND.
• To evaluate the impact of the Communities That HEAL intervention on coalition capabilities and OEND implementation.

Main Methods:

• A multisite, cluster randomized waitlist-controlled trial was conducted.
• Longitudinal analysis of cross-sectional survey data from 33 communities (January 2021-June 2022).
• Validated scales measured coalition capacity and leadership; OEND adoption and reach were assessed by partner engagement rates and naloxone units distributed.

Main Results:

• Increases in general coalition capacity were significantly associated with higher rates of OEND implementation by community partners.
• A 56% increase in engaged partners was observed per unit increase in general capacity scores.
• Changes in coalition leadership and capacity did not significantly correlate with naloxone units distributed.

Conclusions:

• Strengthening general coalition capacity is vital for expanding the adoption of OEND.
• Investment in coalition capabilities enhances the effectiveness of public health interventions to reduce opioid-related fatalities.
• Improving general capacities like data-informed decision-making can accelerate the scaling of evidence-based practices like OEND.
