Raising the bar: translating global guidelines to achieve local policy on cholera elimination in Zambia-a qualitative case study.

BACKGROUND: The global roadmap to eliminating cholera by 2030 relies on early detection and response, vaccination in hotspots and effective partnerships. In sub-Saharan Africa, where 60% of the 2.8 million annual cases occur, cholera elimination requires a multisectoral response. To accelerate progress, improved understanding of how to translate a multisectoral approach to eliminate cholera is needed. METHODS: We evaluated implementation of Zambia's Multisectoral Cholera Elimination Plan (MCEP) using six phases of Graham's Knowledge-to-Action (KTA) framework (adaption, assessing barriers, implementation, monitoring, evaluation and sustaining knowledge use). We reviewed the MCEP to assess the policy environment for supporting implementation and triangulated information from 24 key informant interviews with policy-makers and implementers, 12 in-depth interviews with cholera survivors and focus group discussions with 28 community-based neighbourhood health committee members. Thematic analysis was used to analyse the data. We present our findings under each KTA phase. RESULTS: The MCEP prioritizes actions in hotspots, and vaccinations through a multisectoral governance and coordination structure. The appointment of a coordinator and formation of multisectoral technical working groups (TWGs) have improved dissemination, coordination and the case for additional investments in laboratory capacity, cholera vaccines and infrastructure for water, sanitation, hygiene and decentralized solid waste management. However, slow institutionalization of plans, weak coordination, inadequate funding, poor infrastructure and the coronavirus disease 2019 (COVID-19) pandemic has led to fragmented implementation. The sustainability of the MCEP is not assured without: (1) comprehensive advocacy; (2) resource mobilization (international and national budget commitment); (3) monitoring and evaluation (M&E) of progress; and (4) information synthesis and dissemination for end users. CONCLUSIONS: A multisectoral approach can help gain adequate momentum and efficiencies to eliminate cholera in Zambia, provided stakeholders are fully committed and funding is allocated to support plans. An adaptive collaborative strategy within national guidelines and policies that includes target communities is needed to support local translation, adaptation and concerted efforts to eliminate cholera.
