Healthcare Providers' Perspectives on a Novel Couple-Based HIV Treatment Intervention: A Qualitative Assessment of the Facilitators, Barriers, and Proposed Improvements to Implementation in Zambézia Province, Mozambique.

Mozambique has one of the world's highest HIV/AIDS burdens. Despite significant investment in HIV care and treatment, pregnant and lactating women's retention in care remains suboptimal. One reason for poor maternal retention is lack of male partner support. We tested an interventional couple-based HIV care and treatment, including joint clinical appointments and couple-based educational and support sessions provided by a health counselor and peer educators, respectively. Healthcare providers delivering care for seroconcordant individuals were interviewed regarding their perspectives on facilitators and barriers to the couple-based intervention implementation. Analysis of interview responses was done using MAXQDA. Results pertaining to providers' perspectives on implementation and intervention characteristics were organized, interpreted, and contextualized using the Consolidated Framework for Implementation Research (CFIR 2.0), while providers' suggestions for improvements were coded and organized apart from CFIR. Providers felt the intervention was largely compatible with the local culture, and offered a significant advantage over standard individual-based care by facilitating patient follow-up and reducing wait times by prioritizing couples for services. They also believed it facilitated HIV treatment access through the provision of couple-based counseling that encouraged supportive behaviors towards retention. However, providers reported insufficient privacy to deliver couple-based care at some health facilities and concerns that women in difficult relationships may struggle to meaningfully participate. They suggested providing sessions in alternate clinic settings and offering a limited number of women-only visits. The facilitators and barriers described here contribute to informing the design and implementation of future couple-based interventions to improve HIV care for seroconcordant expectant couples.
