Introduction Antimicrobial resistance (AMR) poses a global health threat, especially in low-income and middle-income countries. Community health workers (CHWs) are key actors in infection management and health promotion; however, their involvement in antimicrobial stewardship (AMS) remains unclear. This study aims to assess CHWs’ roles in AMS, examine their training and support, and evaluate outcomes regarding antibiotic use and resistance.Methods A scoping review was conducted to explore the roles, education, training and antimicrobial-related outcomes of CHWs. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines, with the protocol registered in Open Science Framework. Databases including PubMed, EMBASE and CINAHL were searched for studies published in English and Spanish. A narrative synthesis was applied to the identified articles, with the Integrated Quality Criteria for the Review of Multiple Study Designs and Quality Assessment Tool for Studies with Diverse Designs tools employed to assess the risk of bias.Results Eight studies were identified, conducted in Uganda, Tanzania, Zambia, Pakistan, Bangladesh and Kenya. CHWs were involved in various AMS activities, such as infection prevention, detection and treatment of conditions such as pneumonia and gastrointestinal infections. CHWs contributed to health education, antibiotic prescription (when authorised) and improved adherence to guidelines. Positive outcomes included reduced inappropriate antibiotic use and increased community awareness of AMR. However, the effectiveness of these interventions varied depending on the local context and resources.Conclusions CHWs play an important role in promoting responsible antibiotic use and addressing AMR, particularly in underserved settings. Strengthening their training, expanding selected roles and responsibilities and improving support mechanisms should be considered to enhance their potential contribution to AMS programmes. Further research is needed to optimise CHW interventions and evaluate their long-term impact.
