Purpose <p>To identify training needs related to community-based rehabilitation among commune health workers in Vietnam.</p> Materials and methods <p>This study employed an explanatory sequential mixed-methods cross-sectional design. Quantitative data was first collected via structured surveys with 114 commune health workers, followed by 16 semi-structured in-depth interviews and 2 focus group discussions to explain and contextualize the quantitative findings.</p> Results <p>In the quantitative survey, most participants were female (70.2%). The main professional backgrounds were nursing and general medicine, and none had formal rehabilitation specialization. All surveyed participants (100%) reported a need for further training. The three highest-priority topics were processing and synthesizing survey results using the “Disability Model” form (64.9%); assigning areas of CBR responsibility for CBR collaborators (43.0%); and preparing content and organizing monthly rehabilitation meetings with CBR collaborators (43.0%). Training courses were the most preferred delivery format, and group discussions were the most preferred teaching method. Preferred training venues were district health centers or district-level People’s Committees, with provincial-level officers identified as the preferred trainers. Most participants favored short training courses lasting 1–3 days and delivered once a year. Qualitative findings suggested that these preferences reflected limited formal training, the absence of standardized guidance, and practical constraints related to workload and travel in rural settings.</p> Conclusions <p>Community health workers in rural Vietnam have substantial unmet training needs in community-based rehabilitation. Future capacity-building programs should emphasize practical skills and be delivered through short, face-to-face courses at accessible local venues, with content tailored to the operational realities of primary healthcare settings.</p>
