Background:Effective patient-centered interventions are needed to promote patient engagement in HIV care. We assessed the impact of a patient-centered intervention referred to as enhanced patient care (EPC) on viral suppression among unsuppressed patients living with HIV in Kenya.Setting:Two rural HIV clinics within the Academic Model Providing Access to Health care.Methods:This was a 6-month pilot randomized control trial. The EPC intervention incorporated continuity of clinician-patient relationships, enhanced treatment dialog, and improved patients' clinic appointment scheduling. Provider-patient communication training was offered to all clinicians in the intervention site. We targeted 360 virally unsuppressed patients: (1) 240 in the intervention site with 120 randomly assigned to provider-patient communication (PPC) training + EPC and 120 to PPC training + standard of care (SOC) and (2) 120 in the control site receiving SOC. Logistic regression analysis was applied using R (version 3.6.3).Results:A total of 328 patients were enrolled: 110 (92%) PPC training + EPC, 110 (92%) PPC training + SOC, and 108 (90%) SOC. Participants' mean age at baseline was 48 years (SD: 12.05 years). Viral suppression 6 months postintervention was 84.4% among those in PPC training + EPC, 83.7% in PPC training + SOC, and 64.4% in SOC (P ≤ 0.001). Compared with participants in PPC training + EPC, those in SOC had lower odds of being virally suppressed 6 months postintervention (odds ratio = 0.36, 95% confidence interval: 0.18 to 0.72).Conclusions:PPC training may have had the greatest impact on patient viral suppression. Hence, adequate training and effective PPC implementation strategies are needed.
