MORE: Mobile Outreach Retention and Engagement

  • Priority Population
    People age 18+ who have fallen out of HIV care
  • Setting
  • Location
    Washington, D.C.
  • Intervention Focus
    Re-engagement and retention


The Whitman-Walker Health (WWH) Mobile Outreach Retention and Engagement (MORE) intervention increased retention and viral suppression among people with HIV through a tailored service delivery model, which includes increasing access to supportive services and providing HIV care services in community settings. MORE reaches over 3,600 WWH clients with HIV and increases retention in care by providing mobile medical care outside of clinical settings and expanded supportive services (e.g., rideshare services, flexible health center hours, food cards, referrals for mental health counseling). Since 2016, WWH has implemented the intervention in collaboration with the Washington AIDS Partnership (WAP) and the District of Columbia Department of Health (DC Health) HIV/AIDS, Hepatitis, STD and TB Administration (HASHTA). WWH received funding for MORE from WAP, DC Health HAHSTA, the Bristol Myers Squibb Foundation, MAC AIDS Fund, and ViiV Healthcare.

About the Equity in Evaluation Project

The Center for Innovation and Engagement (CIE) identifies, catalogs, and disseminates evidence-informed interventions. Interventions within the CIE compendium were identified through literature reviews of academic journals, key informant interviews, conference abstract reviews, and requests for information (RFI) surveys. In collaboration with Northwestern University, an evidence rubric based on the CDC’s Prevention Research Synthesis (PRS) criteria was developed to gauge the effectiveness of interventions in improving patient outcomes. Interventions that met the inclusion criteria were reviewed by an Evidence and Dissemination Expert Panel (EDEP), which consisted of experts working across various HIV services and specialties. Each intervention received an “impact score,” measuring its relevance, acceptability, appropriateness, feasibility, transferability, and sustainability. The EDEP selected 16 interventions for the CIE team to include in the compendium. Most of the interventions chosen were published in academic journals.

Following the intervention identification process, the CIE team recognized that a number of innovative intervention models were excluded from the compendium because they lacked the necessary evaluation resources to meet evidence criteria. Using a research equity approach, the CIE team identified three additional promising interventions from the RFI list that did not meet the established evidence threshold and were not identified in the academic literature review process. These interventions were selected to be a part of the CIE Equity in Evaluation Project. This project aims to provide organizations that developed innovative service delivery models with evaluation support. Interventions chosen for the project include the Detroit Health Department’s Link-Up Rx program, Whitman Walker Health’s Mobile Outreach Retention and Engagement (MORE) program, and the Rhode Island Executive Office of Health and Human Services (RI EOHHS) TAVIE Red program.

Intervention teams were paired with consultants who have experience conducting a rigorous evaluation of programs serving people with HIV. Consultants prepared evaluation reports for the three interventions outlining key evaluation findings (e.g., program effectiveness, specific sub-population data) and strategies to sustain or expand future evaluation efforts. The intent was for organizations to use the findings from the analysis to enhance their programs, disseminate their innovative service delivery models, and add to the field of evidence-informed approaches that link, retain, and re-engage people with HIV in care. The inclusion of these three interventions in the Equity in Evaluation Project aims to highlight the need to (1) Increase capacity for health departments and community-based organizations to evaluate and demonstrate the impact of their programs in improving health outcomes for people with HIV, (2) Integrate equity frameworks to improve research and evaluation efforts, (3) Prioritize the work of agencies who may not have the capacity for highlevel data management and analysis or who have limited funding to conduct rigorous analysis and disseminate findings, (4) Highlight and disseminate the work of agencies providing services to priority populations experiencing inequitable outcomes in HIV care and retention (e.g., transgender and nonbinary people, people who use drugs, Black gay, bisexual, and other men who have sex with men).
