Improving management of vaccine supply chains: A multi-methods evaluation of vSTEP in Zambia.

BACKGROUND: Equipping supply chain professionals at all levels of the health care systems with essential leadership and management skills is essential to achieving global immunization targets. Numerous and diverse professional development initiatives have been established to support vaccine supply chain managers in Gavi-eligible countries. However, COVID-19 catalyzed rapid innovation in approaches to support leadership development in times of rapid change, and systematic evaluation of these approaches can inform future workforce development strategies to ensure resilient health systems. Therefore, we sought to evaluate outcomes and short-term impact of the fully virtual Strategic Training Executive Program 2.0 (vSTEP 2.0) program in Zambia on participant engagement, skill development, and application of new skills to improve supply chain performance. METHODS: We used a multi-method design to describe the outcomes and short-term impact of vSTEP 2.0 at three levels: (1) delegate response to the training experience (including participation, completion, and satisfaction); (2) delegate change in leadership skill (including achievement of learning objectives and change in competencies); and (3) application of new skills to impact supply chain performance. RESULTS: The program achieved high levels of engagement and an 83% graduation rate despite the length and rigor of the program. High satisfaction was evidenced by positive feedback from delegates on the quality and relevance of the program, especially in the context of COVID response (100% would "definitely" recommend). Delegates demonstrated significant growth in all domains of leadership competencies and applied their learnings to address a complex challenge in supply chain performance in their home organization. DISCUSSION: These findings demonstrate a strong appetite for leadership development support among vaccine supply chain professionals, especially in times of rapid change such as during the COVID response. These results also demonstrate the feasibility and impact of a fully virtual model for leadership development, with implications well beyond the COVID-19 pandemic.
