"We're Going to Be Here": Providers' Perspectives on Implementing a Revised HIV Care Coordination Program.

As HIV outcomes continue to improve, disparities in viral suppression and care engagement persist, exacerbated by socioeconomic inequities, mental health stressors, systemic racism, HIV-related stigma, and other forms of discrimination. HIV care coordination programs address structural and psychosocial barriers to care and treatment, but these interventions must adapt to the evolving circumstances and perspectives of those expected to participate in them to achieve and sustain maximal impact. In 2009, the New York City Department of Health implemented a Ryan White-funded HIV Care Coordination Program (CCP). The CCP has demonstrated effectiveness, particularly among those newly diagnosed with HIV and those out of care or unsuppressed in the prior year. However, implementation challenges prompted a 2018 redesign to increase provider and client engagement. We conducted 30 semi-structured interviews with providers from six agencies delivering the revised CCP to examine barriers and facilitators to implementation. Providers highlighted the revised CCP's flexible, client-centered approach as a strength, allowing for personalized care plans and improved client engagement. Additionally, they emphasized the contributions of driven, committed staff. However, providers noted several barriers associated with the revised model or its implementation context, including increased paperwork burden, unrealistic service expectations, understaffing, and burnout from uncompensated emotional labor. Our findings suggest the value of retaining a client-centered model while streamlining administrative processes, enhancing training and support for providers, and increasing staff-client ratios. Adjustments based on providers' experience with a complex intervention can improve the fit of the intervention to its intended delivery settings and promote sustainability.
