    Introduction: In Kenya, distance to health facilities, inefficient vertical care delivery and limited financial means are barriers to retention in HIV care. Furthermore, the increasing burden of non-communicable diseases (NCDs) among people living with HIV complicates chronic disease treatment and strains traditional care delivery models. Potential strategies for improving HIV/NCD treatment outcomes are differentiated care, community-based care and microfinance (MF). Methods and analysis: We will use a cluster randomised trial to evaluate integrated community-based (ICB) care incorporated into MF groups in medium and high HIV prevalence areas in western Kenya. We will conduct baseline assessments with n=900 HIV positive members of 40 existing MF groups. Group clusters will be randomised to receive either (1) ICB or (2) standard of care (SOC). The ICB intervention will include: (1) clinical care visits during MF group meetings inclusive of medical consultations, NCD management, distribution of antiretroviral therapy (ART) and NCD medications, and point-of-care laboratory testing; (2) peer support for ART adherence and (3) facility referrals as needed. MF groups randomised to SOC will receive regularly scheduled care at a health facility. Findings from the two trial arms will be compared with follow-up data from n=300 matched controls. The primary outcome will be VS at 18 months. Secondary outcomes will be retention in care, absolute mean change in systolic blood pressure and absolute mean change in HbA1c level at 18 months. We will use mediation analysis to evaluate mechanisms through which MF and ICB care impact outcomes and analyse incremental cost-effectiveness of the intervention in terms of cost per HIV suppressed person-time, cost per patient retained in care and cost per disability-adjusted life-year saved. Ethics and dissemination: The Moi University Institutional Research and Ethics Committee approved this study (IREC#0003054). We will share data via the Brown University Digital Repository and disseminate findings via publication.

    Integrating community-based HIV and non-communicable disease care with microfinance groups: a feasibility study in Western Kenya
    (BMC, 2022-12-28) Kafu, Catherine; Wachira, Juddy; Omodi, Victor; Said, Jamil; Pastakia, Sonak D.; Tran, Dan N.; Adongo Onyango, Jael; Aburi, Dan; Wilson‑Barthes, Marta; Galárraga, Omar; Genberg, Becky Lynn; Medicine, School of Medicine
    Background: The Harambee study is a cluster randomized trial in Western Kenya that tests the effect, mechanisms, and cost-effectiveness of integrating community-based HIV and non-communicable disease care within microfinance groups on chronic disease treatment outcomes. This paper documents the stages of our feasibility study conducted in preparation for the Harambee trial, which include (1) characterizing the target population and gauging recruitment capacity, (2) determining community acceptability of the integrated intervention and study procedures, and (3) identifying key implementation considerations prior to study start. Methods: Feasibility research took place between November 2019 and February 2020 in Western Kenya. Mixed methods data collection included surveys administered to 115 leaders of 105 community-based microfinance groups, 7 in-person meetings and two workshops with stakeholders from multiple sectors of the health system, and ascertainment of field notes and geographic coordinates for group meeting locations and HIV healthcare facilities. Quantitative survey data were analyzed using STATA IC/13. Longitude and latitude coordinates were mapped to county boundaries using Esri ArcMap. Qualitative data obtained from stakeholder meetings and field notes were analyzed thematically. Results: Of the 105 surveyed microfinance groups, 77 met eligibility criteria. Eligible groups had been in existence from 6 months to 18 years and had an average of 22 members. The majority (64%) of groups had at least one member who owned a smartphone. The definition of "active" membership and model of saving and lending differed across groups. Stakeholders perceived the community-based intervention and trial procedures to be acceptable given the minimal risks to participants and the potential to improve HIV treatment outcomes while facilitating care integration. Potential challenges identified by stakeholders included possible conflicts between the trial and existing community-based interventions, fear of group disintegration prior to trial end, clinicians' inability to draw blood for viral load testing in the community, and deviations from standard care protocols. Conclusions: This study revealed that it was feasible to recruit the number of microfinance groups necessary to ensure that our clinical trial was sufficient powered. Elicitation of stakeholder feedback confirmed that the planned intervention was largely acceptable and was critical to identifying challenges prior to implementation.
