Using a Collective Impact framework to evaluate an Australian health alliance for improving health outcomes.

Complex social issues such as population health mean that no one person, organization or sector can resolve these problems alone and instead require a collaborative approach. This study applied the Collective Impact framework to evaluate the alliance responsible for delivering a large-scale health promotion initiative. Committee meeting minutes for a 4-year period and qualitative interviews with key stakeholders (N = 14) involved in the design and implementation of the initiative explored the factors that contributed to collaborative efforts and initiative outcomes. Major strengths of the Healthier Queensland Alliance (the Alliance) stemmed from identifying a common agenda and using frequent communication to develop trust among Alliance partners. These processes were important, particularly in improving key relationships to ensure inclusivity and equity. Reinforcing activities helped to support individual organizational efforts, while shared measurement systems promoted data-driven decision-making and learning, which contributed to continuous improvement and innovation. Current findings support the use of the Collective Impact framework as a scaffold to assist collaborative alliances in working effectively and efficiently when implementing large-scale initiatives aiming to create positive social impact. This study has identified the foundations of practice to establish a successful Collective Impact alliance.
