Despite their unique contributions to heart failure (HF) care, home healthcare workers (HHWs) have unmet educational needs and many lack HF caregiving self-efficacy. To address this, we used a community-partnered approach to develop and pilot a HF training course for HHWs. We used a mixed methods design with pre/post surveys and semi-structured interviews to evaluate the course on feasibility, acceptability, and effectiveness. Post-training data showed significant improvements in HF knowledge and HF caregiving self-efficacy.
