From Brazil to the UK and back: Bidirectional learning through community health worker partnerships

Background/aim Bidirectional learning as a means to mutually benefit the exchange of knowledge across settings is a powerful approach for strengthening health systems globally. This paper presents a case study of bidirectional learning through community health worker (CHW) programmes, focusing on the long-established Brazilian Family Health Strategy, particularly CHWs and their adaptation in the UK as Community Health and Wellbeing Workers. Methods We explore the central role of equitable collaborative partnerships and inclusive leadership in enabling effective bidirectional learning, emphasising principles of coproduction, shared capacity building and cultural competency. Drawing on experiences from the Brazilian and UK stakeholders, including health ministries, academic institutions and local governments, we highlight practical strategies to navigate challenges such as power imbalances, differing health system contexts and operational barriers. Results Key facilitators of successful bidirectional learning include establishing clear shared goals, cultivating trust, creating spaces for continuous dialogue and enabling joint learning opportunities such as exchange visits, workshops and training. These findings advance understanding of how global health partnerships can foster innovation, enhance equity and support sustainable health system strengthening. This is the first documented case of formalised CHW bidirectional learning between Brazil and the UK, offering a novel case for global health collaboration. Conclusion Our experience highlights the importance of intentional, structured and ethically grounded partnerships that respect diverse knowledge systems and ensure mutual benefit. This approach has broad applicability for international health and leadership collaborations, aiming to improve community health outcomes worldwide.
