Interventions to improve retention in HIV primary care: a systematic review of U.S. studies

Brief Telephonic Motivational Interviewing for People Living with HIV with Follow-up Problems

Motivational interviewing (MI)-based interventions can be effective for people living with HIV (PLWHIV) with medical follow-up problems. This study aimed to assess the stage of motivation to attend medical appointments of PLWHIV with medical follow-up problems and to evaluate a single telephone session MI intervention directed to engage them in care. The change in stage was evaluated before and after the intervention, and attending medical appointments was monitored for six months. Thirty-nine PLWHIV participated; 51.3% were in precontemplation/contemplation and 49.7% in preparation/action stage. Most (excluding those in the action stage from the beginning) (n = 22, 71.0%) advanced to another stage after the intervention (z = - 4.235, p < .001), and most did not miss the following appointments. Brief and remote MI interventions could be useful in low-resource settings, especially for those in the early stages of change, to explore motivations related with missing medical appointments.

Patient Education and Decision Support for Long-Acting Injectable HIV Antiretroviral Therapy: Protocol for Tool Development and Pilot Testing with Ryan White HIV/AIDS Program Medical Case Management Programs in New York

BACKGROUND

Long-acting injectable (LAI) HIV antiretroviral therapy (ART) presents a major opportunity to facilitate and sustain HIV viral suppression, thus improving health and survival among people living with HIV and reducing the risk of onward transmission. However, realizing the public health potential of LAI ART requires reaching patients who face barriers to daily oral ART adherence and thus can clinically benefit from alternative treatment modalities. Ryan White HIV/AIDS Program Part A medical case management (MCM) programs provide an array of services to address barriers to HIV care and treatment among economically and socially marginalized people living with HIV. These programs have demonstrated effectiveness in improving engagement along the continuum of care, but findings of limited program impact on durable viral suppression highlight the need to further innovate and hone strategies to support long-term ART adherence.

OBJECTIVE

This study aims to adapt and expand Ryan White MCM service strategies to integrate LAI ART regimen options, with the larger goal of improving health outcomes in the populations that could most benefit from alternatives to daily oral ART regimens.

METHODS

In 3 phases of work involving patient and provider participants, this study uses role-specific focus groups to elicit perceptions of LAI versus daily oral ART; discrete choice experiment (DCE) surveys to quantify preferences for different ART delivery options and related supports; and a nonrandomized trial to assess the implementation and utility of newly developed tools at 6 partnering Ryan White HIV/AIDS Program Part A MCM programs based in urban, suburban, and semirural areas of New York. Findings from the focus groups and DCEs, as well as feedback from advisory board meetings, informed the design and selection of the tools: a patient-facing, 2-page fact sheet, including frequently asked questions and a side-by-side comparison of LAI with daily oral ART; a patient-facing informational video available on YouTube (Google Inc); and a patient-provider decision aid. Implementation outcomes, measured through provider interviews, surveys, and service reporting, will guide further specification of strategies to integrate LAI ART options into MCM program workflows.

RESULTS

The study was funded in late April 2021 and received approval from the institutional review board in May 2021 under protocol 20-096. Focus groups were conducted in late 2021 (n=21), DCEs ran from June 2022 to January 2023 (n=378), and tools for piloting were developed by May 2023. The trial (May 2023 through January 2024) has enrolled >200 patients.

CONCLUSIONS

This study is designed to provide evidence regarding the acceptability, feasibility, appropriateness, and utility of a package of patient-oriented tools for comparing and deciding between LAI ART and daily oral ART options. Study strengths include formative work to guide tool development, a mixed methods approach, and the testing of tools in real-world safety-net service settings.

HIV Prevention and Treatment Interventions for Black Men Who Have Sex With Men in Canada: Scoping Systematic Review

BACKGROUND

Black men who have sex with men (MSM) experience disproportionately high HIV incidence globally. A comprehensive, intersectional approach (race, gender, and sexuality or sexual behavior) in understanding the experiences of Black MSM in Canada along the HIV prevention and care continuums has yet to be explored.

OBJECTIVE

This scoping review aims to examine the available evidence on the access, quality, gaps, facilitators, and barriers of engagement and identify interventions relevant to the HIV prevention and care continuum for Black MSM in Canada.

METHODS

We conducted a systematic database search, in accordance with the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) checklist, of the available studies on HIV health experience and epidemiology concerning Black MSM living with or without HIV in Canada and were published after 1983 in either English or French. Searched databases include MEDLINE, Excerpta, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, the NHUS Economic Development Database, Global Health, PsycInfo, PubMed, Scopus, and Web of Science. From the 3095 articles identified, 19 met the inclusion criteria and were analyzed.

RESULTS

Black MSM in Canada consistently report multiple forms of stigma and lack of community support contributing to an increased HIV burden. They experience discrimination based on their intersectional identities while accessing HIV preventative and treatment interventions. Available data demonstrate that Black MSM have higher HIV incidences than Black men who have sex with women (MSW) and White MSM, and low preexposure prophylaxis knowledge and HIV literacy. Black MSM experience significant disparities in HIV prevention and care knowledge, access, and use. Structural barriers, including anti-Black racism, homophobia, and xenophobia, are responsible for gaps in HIV prevention and care continuums, poor quality of care and linkage to HIV services, as well as a higher incidence of HIV.

CONCLUSIONS

Considering the lack of targeted interventions, there is a clear need for interventions that reduce HIV diagnoses among Black MSM, increase access and reduce structural barriers that significantly affect the ability of Black MSM to engage with HIV prevention and care, and address provider's capacity for care and the structural barriers. These findings can inform future interventions, programming, and tools that may alleviate this HIV inequity.

Stakeholder-led design of a mobile HIV clinic model to enhance engagement and retention in HIV care in the Southern United States

To foster retention of people living with HIV (PLWH) in HIV care in the Southern United States, we aimed to develop a stakeholder-driven mobile HIV clinic (MHC) model. From June 2019 to May 2021 we conducted a mixed-methods study: 50 surveys with out-of-care PLWH and 41 in-depth interviews with PLWH, HIV clinic staff, city officials, AIDS service organizations, and mobile clinics to examine preferences for MHC implementation. Survey data was analyzed descriptively, and interview transcripts were coded thematically. Participants recommended the MHC: (1) have nondescript exterior and HIV services nested in non-HIV care to foster confidentiality, (2) be located along public transportation and have extended hours to promote accessibility, (3) have established protocols addressing security, biosafety, and data safety; (4) provide comprehensive clinical and support services to address retention barriers; and (5) be integrated within the health system, use low-cost, diverse staffing, and establish appointment notification systems. By informing MHC design, these findings add to the toolbox of strategies that can render HIV care more accessible.

Study protocol for data to suppression (D2S): a cluster-randomised, stepped-wedge effectiveness trial of a reporting and capacity-building intervention to improve HIV viral suppression in housing and behavioural health programmes in New York City

INTRODUCTION

With progress in the 'diagnose', 'link' and 'retain' stages of the HIV care continuum, viral suppression (VS) gains increasingly hinge on antiretroviral adherence among people with HIV (PWH) retained in care. The Centers for Disease Control and Prevention estimate that unsuppressed viral load among PWH in care accounts for 20% of onward transmission. HIV intervention strategies include 'data to care' (D2C)-using surveillance to identify out-of-care PWH for follow-up. However, most D2C efforts target care linkage, not antiretroviral adherence, and limit client-level data sharing to medical (versus support-service) providers. Drawing on lessons learnt in D2C and successful local pilots, we designed a 'data-to-suppression' intervention that offers HIV support-service programmes surveillance-based reports listing their virally unsuppressed clients and capacity-building assistance for quality-improvement activities. We aimed to scale and test the intervention in agencies delivering Ryan White HIV/AIDS Programme-funded behavioural health and housing services.

METHODS AND ANALYSIS

To estimate intervention effects, this study applies a cross-sectional, stepped-wedge design to the intervention's rollout to 27 agencies randomised within matched pairs to early or delayed implementation. Data from three 12-month periods (pre-implementation, partial implementation and full implementation) will be examined to assess intervention effects on timely VS (within 6 months of a report listing the client as needing follow-up for VS). Based on projected enrolment (n=1619) and a pre-implementation outcome probability of 0.40-0.45, the detectable effect size with 80% power is an OR of 2.12 (relative risk: 1.41-1.46).

ETHICS AND DISSEMINATION

This study was approved by the New York City Department of Health and Mental Hygiene's institutional review board (protocol: 21-036) with a waiver of informed consent. Findings will be disseminated via publications, conferences and meetings including provider-agency representatives.

A Trauma-Informed HIV Intervention (LinkPositively) to Improve HIV Care Among Black Women Affected by Interpersonal Violence: Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

Black women bear a disproportionate burden of HIV, accounting for nearly 60% of new diagnoses among US women. Black women living with HIV often experience mutually reinforcing epidemics, known as syndemics, including interpersonal violence and substance use. Syndemics are associated with decreased HIV care engagement and treatment adherence and worsening HIV outcomes. Few HIV services and resources are tailored to be culturally and gender-responsive and trauma informed for Black women living with HIV. Technology-based, psychoeducational, and peer navigation programs offer promising pathways to tailored HIV support and improved HIV care outcomes. Therefore, the web-based, trauma-informed intervention LinkPositively was developed in collaboration with Black women living with HIV to promote uptake of HIV care and ancillary support services.

OBJECTIVE

This study primarily determines the feasibility and acceptability of the LinkPositively intervention among Black women living with HIV affected by interpersonal violence. The secondary aim is to examine the preliminary impact of the LinkPositively intervention on retention in HIV care, antiretroviral therapy adherence, and viral suppression while evaluating the role of mechanism of change variables (eg, social support) in the associations.

METHODS

The LinkPositively trial is a pilot randomized controlled trial conducted in California, United States, among 80 adult Black women living with HIV who have experienced interpersonal violence. Core components of LinkPositively include one-on-one peer navigation with phone and SMS text message check-ins; 5 weekly one-on-one video sessions to build coping and care navigation skills; and a mobile app that contains a peer support social networking platform, an educational database with healthy living and self-care tips, a GPS-enabled HIV and ancillary care resource locator, and a medication self-monitoring and reminder system. Participants are randomly assigned to the intervention (n=40) or control (Ryan White standard of care; n=40) arm, with follow-up at 3 and 6 months. At each assessment, participants complete an interviewer-administered survey and submit hair samples for the assessment of HIV medication adherence. All research staff and investigators adhere to ethical principles and guidelines for conducting research activities. Data will be analyzed using generalized estimating equations.

RESULTS

Final development and testing of the LinkPositively app were completed in July 2021. As of May 2023, we have screened 97 women for eligibility. Of the 97 women screened, 27 (28%) were eligible and have been enrolled in the study. The dissemination of preliminary results will occur in 2024.

CONCLUSIONS

This trial will advance HIV prevention science by harnessing technology to promote engagement in HIV care while improving social support through peers and social networking-all while being trauma informed for Black women living with HIV with experiences of interpersonal violence. If shown to be feasible and acceptable, LinkPositively has the potential to improve HIV care outcomes among Black women, a marginalized key population.

HIV medical care interruption among people living with HIV in Spain, 2004-2020

OBJECTIVE

We estimated the incidence rate of HIV medical care interruption (MCI) and its evolution over a 16-year-period, and identified associated risk factors among HIV-positive individuals from the Cohort of the Spanish AIDS Research Network in 2004-2020.

DESIGN

We included antiretroviral-naive individuals aged at least 18 years at enrolment, recruited between January 1, 2004, and August 30, 2019, and followed-up until November 30, 2020.

METHODS

Individuals with any time interval of at least 15 months between two visits were defined as having a MCI. We calculated the incidence rate (IR) of having at least one MCI and used multivariable Poisson regression models to identify associated risk factors.

RESULTS

Of 15 274 individuals, 5481 (35.9%) had at least one MCI. Of those, 2536 (46.3%) returned to HIV care after MCI and 3753 (68.5%) were lost to follow-up at the end of the study period. The incidence rate (IR) of MCI was 7.2/100 person-years (py) [95% confidence interval (CI): 7.0-7.4]. The annual IR gradually decreased from 20.5/100 py (95% CI: 16.4-25.6) in 2004 to 4.9/100 py (95% CI: 4.4-5.5) in 2014, a slight increase was observed between 2015 and 2018, reaching 9.3/100 py (95% CI: 8.6-10.2) in 2019. Risk factors for MCI included younger age, lower educational level, having contracted HIV infection through injecting drug use or heterosexual intercourse, having been born outside of Spain, and CD4 + cell count >200 cell/μl, viral load <100 000 and co-infection with hepatitis C virus at enrolment.

CONCLUSIONS

Around a third of individuals had at least one MCI during the follow-up. Identified predictors of MCI can help health workers to target and support most vulnerable individuals.

Prioritization of Evidence-Based and Evidence-Informed Interventions for Retention in Medical Care for Persons with HIV

Up to 50% of those diagnosed with HIV in the U.S. are not retained in medical care. Care retention provides opportunity to monitor benefits of HIV therapy and enable viral suppression. To increase retention, there is a need to prioritize best practices appropriate for translation and dissemination for real-world implementation. Eighteen interventions from CDC's Compendium of Evidence-Based Interventions were scored using the RE-AIM framework to determine those most suitable for dissemination. A CDC Division of HIV Prevention workgroup developed a RE-AIM scale with emphasis on the Implementation and Maintenance dimensions and less emphasis on the Efficacy dimension since all 18 interventions were already identified as evidence-based or evidence-informed. Raters referenced primary efficacy publications and scores were averaged for a ranked RE-AIM score for interventions. Of 18 interventions, four included care linkage and 7 included viral suppression outcomes. Interventions received between 20.6 and 35.3 points (45 maximum). Scores were converted into a percentage of the total possible with ranges between 45.8 and 78.4%. Top four interventions were ARTAS (78.4%); Routine Screening for HIV (RUSH) (73.2%); Optn4Life (67.4%) and Virology Fast Track (65.9%). All four scored high on Implementation and Maintenance dimensions. Select items within the scale were applicable to health equity, covering topics such as reaching under-served focus populations and acceptability to that population. Navigation-enhanced Case Management (NAV) scored highest on the health equity subscale. RE-AIM prioritization scores will inform dissemination and translation efforts, help clinical staff select feasible interventions for implementation, and support sustainability for those interventions.

Retention and Predictors of Attrition Among HIV-infected Children on Antiretroviral Therapy in Côte d'Ivoire Between 2012 and 2016

BACKGROUND

An estimated 21,000 children 0-14 years of age were living with HIV in Côte d'Ivoire in 2020, of whom only 49% have been diagnosed and are receiving antiretroviral therapy (ART). Retention in HIV care and treatment is key to optimize clinical outcomes. We evaluated pediatric retention in select care and treatment centers (CTCs) in Côte d'Ivoire.

METHODS

We retrospectively reviewed medical records using 2-stage cluster sampling for children under 15 years initiated on ART between 2012 and 2016. Kaplan-Meier time-to-event analysis was done to estimate cumulative attrition rates per total person-years of observation. Cox proportional hazard regression was performed to identify factors associated with attrition.

RESULTS

A total of 1198 patient records from 33 CTCs were reviewed. Retention at 12, 24, 36, 48 and 60 months after ART initiation was 91%, 84%, 74%, 72% and 70%, respectively. A total of 309 attrition events occurred over 3169 person-years of follow-up [266 children were lost to follow-up (LTFU), 29 transferred to another facility and 14 died]. LTFU determinants included attending a "public-private" CTC [adjusted hazard ratio (aHR) 6.05; 95% confidence interval (CI): 4.23-8.65], receiving care at a CTC without an on-site laboratory (aHR: 4.01; 95% CI: 1.70-9.46) or attending a CTC without an electronic medical record (EMR) system (aHR: 2.22; 95% CI: 1.59-3.12).

CONCLUSIONS

In Cote d'Ivoire, patients attending a CTC that is public-private, does not have on-site laboratory or EMR system were likely to be LTFU. Decentralization of laboratory services and scaling use of EMR systems could help to improve pediatric retention.

Study protocol for a multisite randomized controlled trial of a peer navigator intervention for emergency department patients with nonfatal opioid overdose

BACKGROUND

Patients presenting to emergency departments (EDs) after a nonfatal opioid-involved overdose are at high risk for future overdose and death. Responding to this risk, the New York City (NYC) Department of Health and Mental Hygiene operates the Relay initiative, which dispatches trained peer "Wellness Advocates" to meet patients in the ED after a suspected opioid-involved overdose and follow them for up to 90 days to provide support, education, referrals to treatment, and other resources using a harm reduction framework.

METHODS

In this article, we describe the protocol for a multisite randomized controlled trial of Relay. Study participants are recruited from four NYC EDs and are randomized to receive the Relay intervention or site-directed care (the control arm). Outcomes are assessed through survey questionnaires conducted at 1-, 3-, and 6-months after the baseline visit, as well as through administrative health data. The primary outcome is the number of opioid-related adverse events, including any opioid-involved overdose or any other substance use-related ED visit, in the 12 months post-baseline. Secondary and exploratory outcomes will also be analyzed, as well as hypothesized mediators and moderators of Relay program effectiveness.

CONCLUSION

We present the protocol for a multisite randomized controlled trial of a peer-delivered OD prevention intervention in EDs. We describe how the study was designed to minimize disruption to routine ED operations, and how the study was implemented and adapted during the COVID-19 pandemic. This trial is registered with ClinicalTrials.gov [NCT04317053].

Factors associated with quality of life, depressive symptoms, and perceived stress among rural older adults living with HIV in the United States

PURPOSE

Rural older people living with HIV (PLH) in the United States are a population of growing size and significance. A better understanding of factors associated with quality of life (QOL), depressive symptoms, and stress in this population-especially modifiable factors-could inform future interventions.

METHODS

Online or on paper, we surveyed 446 PLH aged 50+ residing in rural counties across the United States (Mage = 56, 67% male, 67% White, and 23% Black). Associations between social support, HIV stigma, satisfaction with medical care, discrimination in health care settings, and structural barriers and health-related QOL, depressive symptoms, and perceived stress were assessed using multiple linear regressions.

FINDINGS

Controlling for demographics, greater social support was associated with better QOL, fewer depressive symptoms, and less stress. Greater HIV stigma was associated with more depressive symptoms and stress. Satisfaction with care was associated with better QOL and less stress. Discrimination in medical settings was associated with lower QOL and more depressive symptoms and stress. Finally, experiencing more structural barriers was associated with lower QOL and more depressive symptoms and stress.

CONCLUSIONS

In addition to engagement in care and viral suppression, QOL and mental health are also critical considerations for rural older PLH. Increasing social support, reducing or providing skills to cope with HIV stigma, improving quality of care, reducing discrimination and stigma in medical settings, and reducing or mitigating the impact of structural barriers present potential targets for interventions aiming to improve the well-being of older rural PLH.

Reaching and Re-Engaging People Living with HIV Who Are Out of Care: A Mixed-Methods Exploration of Patient Preferences for Strategies to Enhance Clinic Communication and Outreach

Half of all people living with HIV (PLWH) in the United States are not retained in HIV medical care. The utility of appointment reminders and clinic-based retention support services is often limited by the inability to contact PLWH who are out of care (PLWH-OOC) due to disconnected phone lines, full voice mails, and housing instability. Between June 2019 and May 2021, as part of a larger mixed-methods study in Metro Atlanta, Georgia, we conducted surveys with 50 PLWH-OOC and interviews with 13 PLWH holding a variety of clinic stakeholder roles (patients, Community Advisory Board members, and peer navigators) to explore preferences for clinic communication and peer outreach and factors impacting uptake. Although phone calls, text messages, and calling secondary contacts were most preferred, the spread of preferences was wide. Surveys and interviews highlighted the high acceptance of peer outreach visits, with trust, support, and privacy being key factors driving the uptake. Findings underscore the need for clinics to offer a suite of communication and outreach strategies and assess patient preferences for traditional and nontraditional outreach models to more effectively reach, re-engage, and ultimately retain PLWH-OOC.

Brief Report: Physician Reimbursement and Retention in HIV Care: Racial Disparities in the US South

BACKGROUND

Retention in HIV care remains a national challenge. Addressing structural barriers to care may improve retention. We examined the association between physician reimbursement and retention in HIV care, including racial differences.

METHODS

We integrated person-level administrative claims (Medicaid Analytic eXtract, 2008-2012), state Medicaid-to-Medicare physician fee ratios (Urban Institute, 2008, 2012), and county characteristics for 15 Southern states plus District of Columbia. The fee ratio is a standardized measure of physician reimbursement capturing Medicaid relative to Medicare physician reimbursement across states. Generalized estimating equations assessed the association between the fee ratio and retention (≥2 care markers ≥90 days apart in a calendar year). Stratified analyses assessed racial differences. We varied definitions of retention, subsamples, and definitions of the fee ratio, including the fee ratio at parity.

RESULTS

The sample included 55,237 adult Medicaid enrollees with HIV (179,002 enrollee years). Enrollees were retained in HIV care for 76.6% of their enrollment years, with retention lower among non-Hispanic Black (76.1%) versus non-Hispanic White enrollees (81.3%, P < 0.001). A 10-percentage point increase in physician reimbursement was associated with 4% increased odds of retention (adjusted odds ratio 1.04, 95% confidence interval: 1.01 to 1.07). In stratified analyses, the positive, significant association occurred among non-Hispanic Black (1.08, 1.05-1.12) but not non-Hispanic White enrollees (0.87, 0.74-1.02). Findings were robust across sensitivity analyses. When the fee ratio reached parity, predicted retention increased significantly overall and for non-Hispanic Black enrollees.

CONCLUSION

Higher physician reimbursement may improve retention in HIV care, particularly among non-Hispanic Black individuals, and could be a mechanism to promote health equity.

Health literacy, health outcomes and community health worker utilization: a cohort study in HIV primary care

Background

People with HIV (PWH) have complex needs, and those with limited health literacy consistently have poorer HIV-related knowledge and health outcomes. One strategy to facilitate better outcomes for PWH is the inclusion of community health workers (CHWs) into care teams. This cohort study examines the effect of health literacy on clinical outcomes and utilization of CHW services among PWH enrolled in a CHW intervention. The secondary aim is to characterize most common purposes of CHW encounters.

Methods

PWH (n = 209) enrolled in a CHW intervention with completed 6-month follow-up evaluation visits were included. Health literacy level was measured at baseline with the BRIEF tool and categorized into inadequate, marginal, and adequate health literacy. Adjusted logistic regressions assessed the effect of health literacy on viral load suppression, HIV primary care visits at 6-month follow-up, CHW utilization and purpose of CHW encounter. Purpose of CHW encounters included logistical support, accompany to appointment, transportation coordination, concrete services, coaching, and emotional support. Linear regression assessed the association between purpose of CHW encounters and CHW utilization.

Results

Individuals with inadequate health literacy were more likely to receive coaching from CHWs (p = 0.029), and individuals with marginal health literacy were more likely to have an HIV primary care visit at 6 months (p = 0.044). Individuals receiving transportation coordination, concrete services, coaching, and emotional support had more total CHW encounters.

Conclusions

Purpose of encounter was highly correlated with frequency of CHW encounters, while health literacy status was not. This suggests individuals receiving these services require more assistance from CHWs, regardless of health literacy level. Training CHWs to conduct comprehensive social needs assessment and screening for risk factors at the initial visit with clients can identify resources and guide CHW service delivery as part of the care team.

Socio-Structural Factors and HIV Care Engagement among People Living with HIV during the COVID-19 Pandemic: A Qualitative Study in the United States

Achieving HIV prevention goals will require successful engagement in each stage of the HIV continuum. The present study sought to understand the ways in which socio-structural factors influence HIV care engagement among people living with HIV (PLH) within the context of the ongoing COVID-19 pandemic. Twenty-five PLH were recruited from January to October 2021. Semi-structured interviews discussed various socio-contextual factors that influenced engagement in HIV-related care as a result of the pandemic. A thematic content analysis reported semantic level themes describing factors influencing HIV care following an integrated inductive-deductive approach. Qualitative analysis revealed three themes that either supported or hindered engagement in care within the context of the COVID-19 pandemic: (1) social determinants of health, (2) social support, and (3) modes of healthcare delivery. The results underscore the need to assess socio-structural factors of health as means to promote successful engagement in the HIV care continuum and shed new insights to guide future practice in the era of COVID-19.

Barriers and facilitators to scaling up Healthy Choices, a motivational interviewing intervention for youth living with HIV

Background

This study included Community Health Workers and their supervisors from HIV clinical care teams who participated in the Healthy Choices intervention program. Healthy Choices is a Motivational Interviewing-based intervention aimed at improving medication adherence and reducing alcohol use for adolescents and emerging adults ages 16—24 living with HIV. In this study, the intervention was “scaled up” for delivery by local HIV care providers in real-world clinic settings.

Methods

Providers (N = 21) completed semi-structured interviews (N = 29) about their experiences with intervention scale-up. Rigorous thematic analyses were conducted within discussions of barriers and facilitators of intervention implementation.

Results

Three dominant thematic areas emerged from the data: (1) perceptions of the Healthy Choices intervention, (2) engaging high risk YLH in in-person behavior interventions, and (3) perspectives on implementation of the intervention using local staff. Results offer insights into implementation of MI-based interventions for adolescents and emerging adults in clinic settings using local clinical staff instead of dedicated research staff.

Conclusions

Overall, scaled-up intervention programs for youth are challenged to maintain scientific rigor, provide rigorous training and supports, and offer an attractive and engaging program.

"Patient Lost to Follow-up": Opportunities and Challenges in Delivering Primary Care in Academic Medical Centers

BACKGROUND

Academic health centers (AHCs) face unique challenges in providing continuity to a medically and socially complex patient population. Little is known about what drives patient loss in these settings.

OBJECTIVE

Determine physician- and patient-based factors associated with patient loss in AHCs.

DESIGN

Retrospective cohort study, embedded qualitative analysis.

SETTING

Academic health center.

PARTICIPANTS

All visits from 7/1/2014 to 6/30/2019; 89 physicians (51%) participated in a qualitative analysis.

MEASURES

Physician-based factors (gender, years of service, hours of practice per week, trainee status, and departure during the study period) and patient-based factors (age, gender, race, limited English proficiency, public health insurance, chronic illness burden, and severe psychiatric illness burden) and their association with patient loss to follow-up, defined as a lapse in provider visit greater than 3 years.

RESULTS

We identified 402,415 visits for 41,876 distinct patients. A total of 9332 (22.3%) patients were lost to follow-up. Patient factors associated with loss to follow-up included patient age < 40 (HR 3.12 (2.94-3.33)), identification as non-white (HR 1.07 (1.10-1.13)), limited English proficiency (HR 1.18 (1.04-1.33)), and use of public insurance (HR 1.12 (1.04-1.21)). Provider factors associated with patient loss included trainee status (HR 3.74 (2.43-5.75)) and having recently departed from the practice (HR 1.98, 1.66-2.35). Structured interviews with clinical providers revealed unfavorable relationships with providers and staff (35%), inconvenience accessing primary care (23%), unreliable health insurance (18%), difficulty accessing one's primary care provider (14%), and patient/provider transitions (10%) as reasons for patient loss.

CONCLUSIONS

Younger patient age, markers of social vulnerability, and physician transiency are associated with patient loss at AHCs, providing targets to improve continuity of care within these settings.

The Dose Response Effects of Digital HIV Care Navigation on Mental Health and Viral Suppression Among Young People Living With HIV: Single-Arm, Prospective Study With a Pre-Post Design

BACKGROUND

The HIV epidemic has revealed considerable disparities in health among sexual and gender minorities of color within the Unites States, disproportionately affecting cisgender men who have sex with men (MSM) and trans women. Social inequities further disadvantage those with intersectional identities through homophobia, antitrans discrimination, and racism, shaping not only those at risk for HIV infection but also HIV prevention and care outcomes. Digital interventions have great potential to address barriers and improve HIV care among cisgender MSM and trans women; however, efficacy of digital HIV care interventions vary and need further examination.

OBJECTIVE

This study assessed the 12-month efficacy of a 6-month digital HIV care navigation intervention among young people living with HIV in San Francisco, California. We examined dose-response relationships among intervention exposure (eg, text messaging), viral suppression, and mental health. Health electronic navigation (eNav) is a 6-month, text message-based, digital HIV care navigation intervention, in which young people living with HIV are connected to their own HIV care navigator through text messaging to improve engagement in HIV primary care.

METHODS

This study had a single-arm, prospective, pre-post design. Eligibility criteria for the study included the following: identifying as cisgender MSM or trans women, being between the ages of 18 and 34 years, being newly diagnosed with HIV, or not being engaged or retained in HIV care or having a detectable viral load. We assessed and analyzed sociodemographics, intervention exposure, and HIV care and mental health outcome data for participants who completed the 6-month Health eNav intervention. We assessed all outcomes using generalized estimating equations to account for within-subjects correlation, and marginal effects of texting engagement on all outcomes were calculated over the entire 12-month study period. Finally, we specified an interaction between texting engagement and time to evaluate the effects of texting engagement on outcomes.

RESULTS

Over the entire 12-month period, this study shows that every one-text increase in engagement was associated with an increased odds of undetectable viral load (adjusted odds ratio 1.01, 95% CI 1.00-1.02; P=.03). Mean negative mental health experiences decreased significantly at 12 months compared to baseline for every one-text increase in engagement (coefficient on interaction term 0.97, 95% CI 0.96-0.99; P<.01).

CONCLUSIONS

Digital care navigation interventions including Health eNav may be a critical component in the health delivery service system as the digital safety net for those whose social vulnerability is exacerbated in times of crisis, disasters, or global pandemics owing to multiple social inequities. We found that increased engagement in a digital HIV care navigation intervention helped improve viral suppression and mental health-intersecting comorbid conditions-6 months after the intervention concluded. Digital care navigation may be a promising, effective, sustainable, and scalable intervention.

Associations with sub-optimal clinic attendance and reasons for missed appointments among heterosexual women and men living with HIV in London

Poor engagement in HIV care is associated with poorer health outcomes and increased mortality. Our survey examined experiential and circumstantial factors associated with clinic attendance among women (n = 250) and men (n = 106) in London with heterosexually-acquired HIV. While no associations were found for women, among men, sub-optimal attendance was associated with insecure immigration status (25.6% vs. 1.8%), unstable housing (32.6% vs. 10.2%) and reported effect of HIV on daily activities (58.7% vs. 40.0%). Among women and men on ART, it was associated with missing doses of ART (OR = 2.96, 95% CI:1.74-5.02), less belief in the necessity of ART (OR = 0.56, 95% CI:0.35-0.90) and more concern about ART (OR = 3.63, 95% CI:1.45-9.09). Not wanting to think about being HIV positive was the top reason for ever missing clinic appointments. It is important to tackle stigma and the underlying social determinants of health to improve HIV prevention, and the health and well-being of people living with HIV.

Factors predicting 12-month retention in care for minority women living with HIV

Objectives:

Retention in HIV medical care is associated with improved clinical outcomes and reduced mortality. The present study was conducted to identify significant predictors of 1-year retention in care for a sample of minority women whose engagement in HIV care at baseline varied along the care continuum from newly diagnosed to lost-to-care.

Methods:

One hundred sixty-five cisgender and transgender women living with HIV in a southern US state were offered a multicomponent retention intervention that included outreach, medical case management (MCM), patient navigation services (PN), and a group intervention for stigma. Multilevel logistic regression analysis was performed to identify baseline and intervention predictors of retention in care at 12 months following enrollment.

Results:

Multilevel logistic regression analysis revealed that baseline characteristics such as working significantly reduced the odds of being retained as did increasing CD4 counts. However, greater amounts of patient navigation and medical case management services received increased the odds of being retained.

Conclusion:

MCM services designed to accelerate coordination and linkage or re-linkage to primary care and PN services to help navigate the complex system of HIV offered in the present study are particularly effective for minority women who lack health insurance, have low CD4 counts, and are unemployed.

Implementation and evaluation of patient navigation in Chicago: Insights on addressing the social determinants of health and integrating HIV prevention and care services

Patient navigation is a primary element in linkage to HIV pre-exposure prophylaxis (PrEP) care and linkage to or re-engagement in HIV care, depending on the HIV status of the individual. However, there is a dearth of literature describing navigation services in these areas. In the context of Chicago Project PrIDE, this project conducted process and implementation evaluations with eight agencies leading demonstration projects to address these gaps. The evaluation team conducted semi-structured, individual interviews with agency staff (N = 20) assessing navigation implementation and fit, as well as project successes and challenges. Additionally, agency staff collected patient surveys (N = 300) assessing services provided, service quality, and satisfaction. The interview transcripts were coded and analyzed thematically and descriptive analyses were performed on the survey data. Analyses indicated that screening for social determinants of health, providing healthcare engagement guidance, and providing service referrals were frequently cited navigation activities. Most staff members indicated that navigation fits well within their agencies, and that limited staff and clinic capacity were often barriers to navigation. Patient navigation to support engagement in HIV prevention and care services is critical due to the extensive support provided by navigators to address social determinants of health impacting HIV disparity populations.

Considerations for the Design of Pre-exposure Prophylaxis (PrEP) Interventions for Women: Lessons Learned from the Implementation of a Novel PrEP Intervention

Pre-exposure prophylaxis (PrEP) uptake among women in the United States has been low. To increase uptake, we developed a peer outreach and navigation PrEP intervention. Semi-structured qualitative interviews with 32 cisgender women and 3 transgender women were conducted to assess the intervention. We used a thematic approach to identify barriers to, and facilitators of the intervention. Facilitators included interest in PrEP, offer of health and social services, the intervention’s women-focused approach, and peer outreach and navigation. Barriers were perceived HIV risk, concerns about medication side effects or interactions, housing insecurity and travel, co-occurring health-related conditions, and caregiving responsibilities. We recommend that future interventions consider packaging PrEP in local community settings, such as syringe exchange programs; include services such as food and housing assistance; use peers to recruit and educate women; integrate a culturally appropriate women’s focus; and consider providing same-day PrEP.

The HIV Treat Pillar: An Update and Summary of Promising Approaches

The Treat pillar of the Ending the HIV Epidemic in the U.S. plan calls for comprehensive strategies to enhance linkage to, and engagement in, HIV medical care to improve viral suppression among people with HIV and achieve the goal of 95% viral suppression by 2025. The U.S. has seen large increases in the proportion of people with HIV who have a suppressed viral load. Viral suppression has increased 41%, from 46% in 2010 to 65% in 2018. An additional increase of 46% is needed to meet the Ending the HIV Epidemic in the U.S. goal. The rate of viral suppression among those in care increased to 85% in 2018, highlighting the need to ensure sustained care for people with HIV. Greater increases in all steps along the HIV care continuum are needed for those disproportionately impacted by HIV, especially the young, sexual and racial/ethnic minorities, people experiencing homelessness, and people who inject drugs. Informed by systematic reviews and current research findings, this paper describes more recent promising practices that suggest an impact on HIV care outcomes. It highlights rapid linkage and treatment interventions; interventions that identify and re-engage people in HIV care through new collaborations among health departments, providers, and hospital systems; coordinated care and low-barrier clinic models; and telemedicine-delivered HIV care approaches. The interventions presented in this paper provide additional approaches that state and local jurisdictions can use to reach their local HIV elimination plans' goals and the ambitious Ending the HIV Epidemic in the U.S. Treat pillar targets by 2030.

HIV Engage-A randomized controlled efficacy trial of an acceptance-based behavioral therapy intervention to improve retention in care for HIV treatment naïve patients: Study protocol

INTRODUCTION

People with HIV (PWH) who are not consistently retained in medical care, particularly when they are first diagnosed, are at risk for: delayed antiretroviral therapy (ART) initiation, suboptimal ART adherence, unsuppressed viremia, and mortality. Suboptimal retention means effective ART cannot be leveraged to prevent onward HIV transmission. To address this, we developed and previously pilot tested the HIV Engage intervention-a novel behavioral approach to enhance retention in HIV care using acceptance-based behavioral therapy (ABBT)-and established feasibility and acceptability of this approach. In the current study, we investigate the efficacy of ABBT compared to an attention-matched control condition in a full-scale randomized controlled efficacy trial.

METHODS

Two hundred seventy HIV care naïve patients from geographically diverse clinics will be recruited and equally randomized to receive (a) the HIV Engage intervention, consisting of two 20-30 min ABBT sessions delivered in-person or remotely, or (b) an attention-matched HIV education control condition. Primary outcomes are number of HIV care appointments kept and HIV viral load suppression. Secondary outcomes are higher self-reported ART adherence, HIV status disclosure, increased social support, and reductions in perceived HIV stigma. Hypothesized mediators include acceptance of one's HIV diagnosis and willingness to disclose serostatus. We will also assess for epidemiologically-linked moderators of the treatment effect.

CONCLUSIONS

ABBT represents a novel, potentially promising approach to enhance retention in ongoing HIV care among treatment naïve PWH. This study will contribute significant actionable data establishing the impact, mediational mechanisms, and effect modifiers of ABBT.

Client-led care in HIV: perspectives from community and practice

OBJECTIVES

While current antiretroviral and care strategies can effectively suppress HIV, achieving optimal quality of life (QoL) requires a wider consideration of clients' well-being, the complexity of individuals' lives and social determinants of health. The objective of this commentary was to develop a definition of client-led care in the Australian context and its key supporting principles for people living with HIV (PLHIV).

METHODS

The authors used two sources of evidence to support their HIV community experience with client-led care: (1) a scoping review of the literature, and (2) consultations with colleagues who were PLHIV advocates or HIV specialist physicians. The findings from the scoping review and consultations were summarised and the key principles of client-led care compared with those identified by the authors.

RESULTS

Seven articles met the inclusion criteria for qualitative analysis in the scoping review. Five PLHIV advocates and three HIV specialist physicians were consulted. Key principles supporting client-led care identified by the authors based on their experience centred around the themes of: (1) clients and healthcare providers working in partnership, (2) information and communication, (3) coordinating access to care, (4) building trust, and (5) respect for client's needs and preferences. The principles identified by the authors were supported by those of the scoping review and colleague consultations.

CONCLUSIONS

A client-led approach can complement conventional HIV care strategies and enable empowerment and greater engagement with care, potentially improving the care continuum and overall QoL for individuals living with HIV who can, and want to, lead their own care.

Engagement in HIV Care Among New York City Transgender Women of Color: Findings from the Peer-Led, TWEET Intervention, a SPNS Trans Women of Color Initiative

Transgender women (TW) have higher HIV prevalence rates than cisgender (i.e., non-transgender) women. However, utilization of healthcare for transgender people in the U.S. is low. As part of a multisite initiative to facilitate entry and retention in HIV care for TW of color, we compared health outcomes between participants who became Peer Leaders and those who did not. From 2013 to 2016, 163 New York City, mostly Latina, TW enrolled in the Transgender Women Engagement and Entry to Care Project (TWEET). The TWEET intervention included peer-led, group-based educational sessions called Transgender Leader-Teach Back; 39% completed Peer Leadership requirements. Comparing pre-post change by Peer Leader status, Peer Leaders had a significant decrease in viral load and significant increase in CD4 at the last HIV care visit compared to the first. In multivariable logistic regression, predictors associated with Peer Leadership included having at least some college education, being in a relationship, stable housing, receiving legal assistance for political asylum, and having two or more HIV care visits during the intervention. Findings suggest that, for trans women who have completed at least secondary school education, participating in a peer-led intervention can lead to improved HIV care engagement. Understanding which program components lead to becoming a Peer Leader, and how to better engage non-Peer Leaders, are important next steps.

Retention in Medical Care Among Insured Adolescents and Young Adults With Diagnosed HIV Infection, United States, 2010-2014

OBJECTIVES

Retention in care is a critical component of effective HIV treatment, and adolescents and young adults are at higher risk of inadequate retention than older adults. The objective of our study was to examine the patterns of retention in care among adolescents and young adults with HIV infection by analyzing Medicaid and commercial health insurance claims data.

METHODS

We evaluated retention in care for HIV-diagnosed adolescents and young adults aged 13-24 using the 2010-2014 MarketScan Medicaid and MarketScan Commercial Claims health insurance databases. The study period extended 36 months from the date of the first claim with a code for HIV or AIDS. We determined the unweighted proportion retained in care for the Medicaid and Commercial Claims cohorts for months 0-24 and 25-36. We assessed associations between demographic characteristics and retention in care using logistic regression.

RESULTS

A total of 378 adolescents and young adults were in the Medicaid cohort and 1028 in the Commercial Claims cohort. In the Medicaid and Commercial Claims cohorts, respectively, 186 (49%) and 591 (57%) adolescents and young adults were retained in care during months 0-24. In the Medicaid cohort, 113 (73%) people retained in care and 69 (45%) people not retained in care during months 0-24 were retained in care during months 25-36. In the Commercial Claims cohort, 313 (77%) and 94 (31%) retained and not retained people, respectively, were found to be in care during months 25-36.

CONCLUSIONS

Notable proportions of HIV-diagnosed adolescents and young adults are not adequately retained in care; public health interventions tailored to this population are needed.

Measuring Unmet Needs among Persons Living with HIV at Different Stages of the Care Continuum

Unmet needs can impede optimal care engagement, impacting the health and well-being of people living with HIV (PLWH); yet, whether unmet needs differ by care engagement status is not well understood. Using surveys and qualitative interviews, we examined and compared unmet needs for PLWH (n = 172) at different levels of care engagement. Unmet needs varied only slightly by care status. Survey findings revealed that provision of housing, emergency financial assistance, employment assistance, and food security were the greatest unmet need; for those in care, housing was the greatest unmet need, whereas for those sporadically in care or out of care, employment assistance was the greatest unmet needs. Qualitative interviews likewise illustrated that a lack of financial resources including insurance, housing, employment, and transportation presented barriers to care engagement across all care groups. Our findings indicate that unmet needs among PLWH are complex and multi-faceted across care engagement status.

Examining Interprofessional Collaboration across case managers, peer educators, and counselors in New York City

Many individuals who are vulnerable to HIV infection and People Living with HIV (PLWH) experience fragmented prevention and care. Prevention and care service integration, pivotal for the HIV care continuum, depends on relationships among service providers and agencies offering HIV services. Case managers, counselors, and peer educators often work together to provide integrated services through interprofessional collaboration (IPC) in HIV prevention and care. Although these providers have distinct job titles, they typically offer complementary services on the HIV care continuum. To better train and allocate professional development resources for these providers, research is needed to assess the overall differences between provider-type and their demographics, intrapersonal factors, and job characteristics most likely to predict IPC engagement. We administered a cross-sectional survey to 75 counselors, 80 peer educators, and 112 case managers in 36 agencies in New York City. We performed a series of linear mixed effects models. Most of the HIV-service providers identified as Black and female and had been working for their agencies for less than a year. Knowledge and skills, self-efficacy, understanding of the community, and greater work hours (> 35 hours) were significant predictors of endorsement of IPC. Peer educators compared to case managers were more likely to reflect on the process as they provide myriad services. Eliciting perspectives from providers allows us to explore interventions, both intra-agency (trainings, greater exposure to collaborative initiatives, and supervision) and interagency (retention programs and websites promoting provider collaboration), that could facilitate IPC engagement and integrated services across the HIV care continuum.

Outcomes and costs of publicly funded patient navigation interventions to enhance HIV care continuum outcomes in the United States: A before-and-after study

BACKGROUND

In the United States, patients with HIV face significant barriers to linkage to and retention in care which impede the necessary steps toward achieving the desired clinical outcome of viral suppression. Individual-level interventions, such as patient navigation, are evidence based, effective strategies for improving care engagement. In addition, use of surveillance and clinical data to identify patients who are not fully engaged in care may improve the effectiveness and cost-effectiveness of these programs.

METHODS AND FINDINGS

We employed a pre-post design to estimate the outcomes and costs, from the program perspective, of 5 state-level demonstration programs funded under the Health Resources and Services Administration's Special Projects of National Significance Program (HRSA/SPNS) Systems Linkages Initiative that employed existing surveillance and/or clinical data to identify individuals who had never entered HIV care, had fallen out of care, or were at risk of falling out of care and navigation strategies to engage patients in HIV care. Outcomes and costs were measured relative to standard of care during the first year of implementation of the interventions (2013 to 2014). We followed patients to estimate the number and proportion of additional patients linked, reengaged, retained, and virally suppressed by 12 months after enrollment in the interventions. We employed inverse probability weighting to adjust for differences in patient characteristics across programs, missing data, and loss to follow-up. We estimated the additional costs expended during the first year of each intervention and the cost per outcome of each intervention as the additional cost per HIV additional care continuum target achieved (cost per patient linked, reengaged, retained, and virally suppressed) 12 months after enrollment in each intervention. In this study, 3,443 patients were enrolled in Louisiana (LA), Massachusetts (MA), North Carolina (NC), Virginia (VA), and Wisconsin (WI) (147, 151, 2,491, 321, and 333, respectively). Patients were a mean of 40 years old, 75% male, and African American (69%) or Caucasian (22%). At baseline, 24% were newly diagnosed, 2% had never been in HIV care, 45% had fallen out of care, and 29% were at risk of falling out of care. All 5 interventions were associated with increases in the number and proportion of patients with viral suppression [percent increase: LA = 90.9%, 95% confidence interval (CI) = 88.4 to 93.4; MA = 78.1%, 95% CI = 72.4 to 83.8; NC = 47.5%, 95% CI = 45.2 to 49.8; VA = 54.6, 95% CI = 49.4 to 59.9; WI = 58.4, 95% CI = 53.4 to 63.4]. Overall, interventions cost an additional $4,415 (range = $3,746 to $5,619), $2,009 (range = $1,516 to $2,274), $920 (range = $627 to $941), $2,212 (range = $1,789 to $2,683), and $3,700 ($2,734 to $4,101), respectively per additional patient virally suppressed. The results of this study are limited in that we did not have contemporaneous controls for each intervention; thus, we are only able to assess patients against themselves at baseline and not against standard of care during the same time period.

CONCLUSIONS

Patient navigation programs were associated with improvements in engagement of patients in HIV care and viral suppression. Cost per outcome was minimized in states that utilized surveillance data to identify individuals who were out of care and/or those that were able to identify a larger number of patients in need of improvement at baseline. These results have the potential to inform the targeting and design of future navigation-type interventions.

A Pilot Study to Evaluate a Novel Pre-exposure Prophylaxis Peer Outreach and Navigation Intervention for Women at High Risk for HIV Infection

Pre-exposure prophylaxis (PrEP) uptake remains woefully low among U.S. women at high risk for HIV acquisition. We evaluated a pilot intervention which involved Peers providing brief PrEP education and counseling at mobile syringe exchange sites and at sex worker and syringe exchange drop-in centers followed by navigation to PrEP care. Peers recruited English-proficient, self-identified women (i.e., cisgender and transgender women and persons with other transfeminine identities) over a 3-month period and delivered the intervention to 52 HIV-negative/status unknown participants. Thirty-eight participants (73.1%) reported PrEP interest, 27 (51.9%) accepted the offer of a PrEP appointment, 13 (25.0%) scheduled a PrEP appointment, 3 (5.8%) attended an initial PrEP appointment, and none were prescribed PrEP. We found a gap between PrEP interest and connecting women to PrEP care. Further study is needed to understand this gap, including exploring innovative approaches to delivering PrEP care to women at highest risk for HIV.

LinkPositively: A Trauma-Informed Peer Navigation and Social Networking WebApp to Improve HIV Care among Black Women Affected by Interpersonal Violence

In the U.S., Black women living with HIV/AIDS (WLHA) are affected disproportionately by interpersonal violence, which often co-occurs with adverse mental health and/or substance use, and exacerbates existing poor HIV care outcomes. Peer navigation has been successful in improving HIV care; however, HIV clinics often lack resources for sustainability and may not account for socio-structural barriers unique to Black WLHA. To address this gap, we developed LinkPositively, a culturally-tailored, trauma-informed WebApp for Black WLHA affected by interpersonal violence to improve HIV care outcomes. Using focus group data from nine Black WLHA and peer navigators, we developed LinkPositively. Core components include: virtual peer navigation to facilitate skill-building to cope with barriers and navigate care; social networking platform for peer support; educational and self-care tips; GPS-enabled resource locator for HIV care and support service agencies; and medication self-monitoring/reminder system. If efficacious, LinkPositively will shift the HIV prevention and care paradigm for Black WLHA.

Salud y Orgullo Mexicano: Development of a Culturally Specific Transnational Linkage and Retention in Care Intervention for Mexican Men Who Have Sex with Men Living with HIV in Chicago

This manuscript documents the development of an innovative individual-level peer navigation intervention "Salud y Orgullo Mexicano" (SOM) designed to increase linkage and retention to HIV care for Mexican men who have sex with men (MSM) in Chicago, Illinois. The intervention was developed via a modified intervention mapping process. Elements of two existing interventions were combined and refined with input from the Mexican MSM community, including informant interviews, an expert advisory board, and a design team. A manualized transnational intervention was developed via intervention mapping. A peer health navigation intervention "SOM" was created using intervention mapping and input from the focus community. Next steps include implementing and evaluating the intervention to determine acceptability and efficacy.

Healthy Choices Intervention is Associated with Reductions in Stigma Among Youth Living with HIV in the United States (ATN 129)

Considering the lack of validated stigma reduction interventions for youth living with HIV (YLWH), we evaluated effects of the Healthy Choices intervention on HIV-related stigma among YLWH. We analyzed data from the Adolescent Medicine Trials Network protocol 129, multi-site randomized controlled trial, applying latent growth curve modeling with two linear slopes estimating changes in Berger's Stigma Scale pre-intervention, 16, 28, and 52 weeks post-intervention, as well as the trajectory of stigma scores over the follow-up period (N = 183). Expected value for the growth intercept was statistically significant (B_intercept = 2.53; 95% CI 2.32, 2.73; p < 0.001), as were differences in the change from baseline to 16-week follow-up (B_{intercept slope1} = - 0.02; 95% CI - 0.04, 0.01; p = 0.034). Expected value of the slope factor measuring growth over the follow-up period was non-significant suggesting that stigma scores were stable from 28 to 52 weeks. Our findings warrant replication and additional research comparing effects of this intervention to counterfactual controls.

Barriers and facilitators to use of a mobile HIV care model to re-engage and retain out-of-care people living with HIV in Atlanta, Georgia

Novel strategies to re-engage and retain people living with HIV (PLWH) who are out of care are greatly needed. While mobile clinics have been used effectively for HIV testing and linkage, evidence guiding their use in providing HIV care domestically has been limited. To guide the development of a mobile HIV clinic (MHC) model as a strategy to re-engage and retain PLWH who are out of care, we aimed to explore stakeholder perceptions of barriers and facilitators to MHC implementation and use. From June 2019-July 2020, we conducted 41 in-depth interviews with HIV clinic providers, administrators, staff, legal authorities, and community advisory board members, PLWH, AIDS service organizations and city officials in Atlanta, Georgia, and domestic and international mobile health clinics to explore barriers and facilitators to use of MHCs. Interviews were transcribed, coded and thematically analysed. Barriers raised include potential for: breach of confidentiality with resulting heightened stigmatization, fractured continuity of care, safety concerns, staffing challenges, and low community acceptance of MHC presence in their locality. Participants provided suggestions regarding appropriate exterior design, location, timing, and co-delivery of non-HIV services that could facilitate MHC acceptance and address the concerns. In identifying key barriers and facilitators to MHC use, this study informs design and implementation of an MHC as a novel strategy for re-engaging and retaining PLWH who are out of care.

Research Synthesis, HIV Prevention Response, and Public Health: CDC's HIV/AIDS Prevention Research Synthesis Project

OBJECTIVE

Research synthesis, through qualitative or quantitative systematic reviews, allows for integrating results of primary research to improve public health. We examined more than 2 decades of work in HIV prevention by the Centers for Disease Control and Prevention's (CDC's) HIV/AIDS Prevention Research Synthesis (PRS) Project. We describe the context and contributions of research synthesis, including systematic reviews and meta-analyses, through the experience of the PRS Project.

METHODS

We reviewed PRS Project publications and products and summarized PRS contributions from 1996 to July 2020 in 4 areas: synthesis of interventions and epidemiologic studies, synthesis methods, prevention programs, and prevention policy.

RESULTS

PRS Project publications summarized risk behaviors and effects of prevention interventions (eg, changing one's perception of risk, teaching condom negotiation skills) across populations at risk for HIV infection and intervention approaches (eg, one-on-one or group meetings) as the HIV/AIDS epidemic and science evolved. We used the PRS Project cumulative database and intervention efficacy reviews to contribute to prevention programs and policies through identification of evidence-based interventions and development of program guidance. Subject matter experts and scientific evidence informed PRS Project products and contributions, which were implemented through strategic programmatic partnerships.

CONCLUSIONS

The contributions of the PRS Project to HIV prevention and public health efforts in the United States can be credited to CDC's long-standing support of the project and its context within a federal prevention agency, where HIV programs and policies were developed and implemented. The effect of the PRS Project was likely facilitated by opportunities to directly influence program and policy because of connections with other research translation activities and program and policy decision making within CDC.

Implementation Science Protocol: evaluating evidence-informed interventions to improve care for people with HIV seen in Ryan White HIV/AIDS program settings

In 2017, the Health Resources and Services Administration's HIV/AIDS Bureau funded an Evaluation Center (EC) and a Coordinating Center for Technical Assistance (CCTA) to oversee the rapid implementation of 11 evidence-informed interventions at 26 HIV care and treatment providers across the U.S. This initiative aims to address persistent gaps in HIV-related health outcomes emerging from social determinants of health that negatively impact access to and retention in care. The EC adapted the Conceptual Model of Implementation Research to develop a Hybrid Type III, multi-site mixed-methods evaluation, described in this paper. The results of the evaluation will describe strategies associated with uptake, implementation outcomes, as well as HIV-related health outcomes for clients engaged in the evidence-informed interventions. This approach will allow us to understand in detail the processes that sites undergo to implement these important intervention strategies for high priority populations.

HIV Patient Navigation in the United States: A Qualitative Meta-Synthesis of Navigators' Experiences

Patient navigation is increasingly used to link and (re)engage persons with human immunodeficiency virus (HIV) to care. A more holistic understanding of patient navigation can be achieved by exploring the experiences of navigators, the persons who comprise half of the navigation process. We conducted a meta-synthesis of navigator experiences with HIV patient navigation using a phenomenological approach. We identified nine relevant studies. Data were analyzed using thematic synthesis. Analysis identified two overarching themes relating to (1) the breadth and depth of bidirectional relationships and functional activities that navigators undertake to connect their clients to care and (2) the inherently personal experience of delivering navigation services. From these thematic findings, we recommend that HIV patient navigators exhibit capacity and expertise in developing and maintaining interpersonal relationships with clients and health care systems/providers and develop self-care practices and emotional boundaries with clients. Our review seeks to advance public health research and practice by articulating key experiences and perspectives of HIV patient navigators, drawing findings and recommendations applicable to the development, implementation, and evaluation of HIV patient navigation.

Modified Antiretroviral Treatment Access Study (MARTAS): A Randomized Controlled Trial of the Efficacy of a Linkage-to-Care Intervention Among HIV-Positive Patients in Ukraine

Between October 2015 and March 2018, we conducted the Modified Antiretroviral Treatment Access Study (MARTAS), a nurse-delivered case management intervention to improve linkage-to-care for persons recently tested HIV positive. Adult participants from nine urban clinics in three regions of Ukraine were randomized to either MARTAS or standard of care (SOC) using individual, parallel, two-arm design. The main study outcome was linkage-to-care (defined as registration at an HIV clinic) within a 3-month period from enrollment in the study. Intention-to-treat analysis of MARTAS (n = 135) versus SOC (n = 139) showed intervention efficacy in linkage to HIV care (84.4% vs. 33.8%; adjusted RR 2.45; 95% CI 1.72, 3.47; p < 0.001). MARTAS is recommended for implementation in Ukraine and may be helpful in other countries with similar gaps in linkage-to-care. Clinicaltrials.gov registration number: NCT02338024.

Improving Care Outcomes for PLWH Experiencing Homelessness and Unstable Housing: a Synthetic Review of Clinic-Based Strategies

PURPOSE OF REVIEW

Singular interventions targeting vulnerable populations of people living with HIV (PLWH) are necessary for reducing new infections and optimizing individual-level outcomes, but extant literature for PLWH who experience homelessness and unstable housing (HUH) has not been compiled. To inform implementation of clinic-based programs that improve care outcomes in this population, we present a synthetic review of key studies examining clinic-based interventions, specifically case management, patient navigation, financial incentives, and the use of mobile technology.

RECENT FINDINGS

Results from unimodal interventions are mixed or descriptive, are limited by inability to address related multi-modal barriers to care, and do not address major challenges to implementation. Multi-component interventions are needed, but gaps in our knowledge base may limit widespread uptake of such interventions before further data are compiled. Future research evaluating interventions for PLWH experiencing HUH should include implementation outcomes in order to facilitate adaptation across diverse clinical settings.

Overview of systematic reviews on strategies to improve treatment initiation, adherence to antiretroviral therapy and retention in care for people living with HIV: part 1

OBJECTIVES

We sought to map the evidence and identify interventions that increase initiation of antiretroviral therapy, adherence to antiretroviral therapy and retention in care for people living with HIV at high risk for poor engagement in care.

METHODS

We conducted an overview of systematic reviews and sought for evidence on vulnerable populations (men who have sex with men (MSM), African, Caribbean and Black (ACB) people, sex workers (SWs), people who inject drugs (PWID) and indigenous people). We searched PubMed, Excerpta Medica dataBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, Web of Science and the Cochrane Library in November 2018. We screened, extracted data and assessed methodological quality in duplicate and present a narrative synthesis.

RESULTS

We identified 2420 records of which only 98 systematic reviews were eligible. Overall, 65/98 (66.3%) were at low risk of bias. Systematic reviews focused on ACB (66/98; 67.3%), MSM (32/98; 32.7%), PWID (6/98; 6.1%), SWs and prisoners (both 4/98; 4.1%). Interventions were: mixed (37/98; 37.8%), digital (22/98; 22.4%), behavioural or educational (9/98; 9.2%), peer or community based (8/98; 8.2%), health system (7/98; 7.1%), medication modification (6/98; 6.1%), economic (4/98; 4.1%), pharmacy based (3/98; 3.1%) or task-shifting (2/98; 2.0%). Most of the reviews concluded that the interventions effective (69/98; 70.4%), 17.3% (17/98) were neutral or were indeterminate 12.2% (12/98). Knowledge gaps were the types of participants included in primary studies (vulnerable populations not included), poor research quality of primary studies and poorly tailored interventions (not designed for vulnerable populations). Digital, mixed and peer/community-based interventions were reported to be effective across the continuum of care.

CONCLUSIONS

Interventions along the care cascade are mostly focused on adherence and do not sufficiently address all vulnerable populations.

An Adherence-Enhancing Program Increases Retention in Care in the Swiss HIV Cohort

Background

This study tested a theory-based adherence-enhancing intervention: the “Interprofessional Medication Adherence Program” (IMAP) to increase human immunodeficiency virus (HIV) retention in care.

Methods

We retrospectively compared our intervention center (intervention group [IG]) with a standard of care center (control group [CG]) both participating in the Swiss HIV Cohort Study between 2004 and 2012. Endpoints were defined as >6-month and >12-month gaps in care for intervals of care longer than 6 and 12 months without any blood draw. Inverse probability of treatment weights was used to adjust for differences between patients at the 2 centers. Viral failure was defined as ribonucleic acid ≥50 copies/mL after 24+ weeks on antiretrovirals.

Results

The IG included 451 patients, CG 311. In the IG, 179 (40%) patients took part in the IMAP for a median of 27 months (interquartile range, 12–45). Gaps in care of ≥6 months were significantly more likely to happen in the CG versus IG (74.6% vs 57%, P < .001). The median time until the first treatment gap was longer in the IG vs CG (120 vs 84 weeks, P < .001). Gaps in care of ≥12 months evaluated in 709 (93%) patients were significantly more likely to occur in the CG compared with the IG (22.6% vs 12.5%, P < .001). The rate of viral failure was significantly lower in the IG (8.3% vs 15.1%, P = .003).

Conclusions

This study, in a real-world setting, shows the effectiveness of the IMAP to reduce 6- and 12-month gaps in follow up among people with HIV. These results should be confirmed by studies in other settings.

STEPS to Care: Translating an Evidence-Informed HIV Care Coordination Program Into a Field-Tested Online Practice Improvement Toolkit

Increasing care engagement is essential to meet HIV prevention goals and achieve viral suppression. It is difficult, however, for agencies to establish the systems and practice improvements required to ensure coordinated care, especially for clients with complex health needs. We describe the theory-driven, field-informed transfer process used to translate key components of the evidence-informed Ryan White Part A New York City Care Coordination Program into an online practice improvement toolkit, STEPS to Care (StC), with the potential to support broader dissemination. Informed by analyses of qualitative and quantitative data collected from eight agencies, we describe our four phases: (1) review of StC strategies and key elements, (2) translation into a three-part toolkit: Care Team Coordination, Patient Navigation, and HIV Self-Management, (3) pilot testing, and (4) toolkit refinement for national dissemination. Lessons learned can guide the translation of evidence-informed strategies to online environments, a needed step to achieve wide-scale implemention.

Adhering to antiretroviral therapy: A qualitative analysis of motivations for and obstacles to consistent use of antiretroviral therapy in people living with HIV

Objectives:

Based on the 2015 U.S. Centers for Disease Control and Prevention data, 40% of people living with HIV in the United States with an HIV diagnosis and 18.5% of people living with HIV in HIV care in the United States are not virally suppressed. Many HIV care clinics have implemented recommendations to improve the percentage of people living with HIV on antiretroviral therapy. To understand what more could be done, we examine patients’ motivations and obstacles to maintaining adherence to antiretroviral therapy.

Methods:

We conducted qualitative analysis using a qualitative description framework of in-depth interviews with people living with HIV receiving care at an urban HIV care clinic in the midwestern United States.

Results:

We found that while many traditional barriers to care have been addressed by existing programs, there are key differences between those consistent with antiretroviral therapy and those inconsistent with antiretroviral therapy. In particular, self-motivation, diagnosis acceptance, treatment for depression, spiritual beliefs, perceived value of the HIV care team, and prior experience with health care distinguish these two groups. Most significantly, we found that people living with HIV consistent with antiretroviral therapy describe their main motivation as coming from themselves, whereas people living with HIV inconsistent with antiretroviral therapy more often describe their main motivation as coming from the HIV care team.

Conclusion:

Our results highlight the importance of the HIV care team’s encouragement of maintaining antiretroviral adherence, as well as encouraging treatment for depression.

Efficacy and Impact of Digital HIV Care Navigation in Young People Living With HIV in San Francisco, California: Prospective Study

BACKGROUND

Young people are disproportionately impacted by HIV infection and exhibit poor HIV care continuum outcomes. Mobile health (mHealth) interventions are promising approaches to meet the unique needs of young people living with HIV. Youth-focused interventions are needed to improve HIV care continuum outcomes.

OBJECTIVE

This study assessed the preliminary efficacy and impact of a digital HIV care navigation intervention among young people living with HIV in San Francisco. Health electronic navigation (eNavigation or eNav) is a 6-month, text message-based, digital HIV care navigation intervention, in which young people living with HIV are connected to their own HIV care navigator through text messaging to improve engagement in HIV primary care.

METHODS

This study had a single-arm, prospective, pre-post design. The analysis included 120 young men who have sex with men or transwomen living with HIV aged between 18 and 34 years. We analyzed self-reported sociobehavioral information pre- and postintervention at baseline and 6 months, which was collected using computer-assisted self-interviewing surveys. We characterized the sample and built generalized estimating equation (GEE) models to assess differences in HIV care continuum outcomes at baseline and 6 months.

RESULTS

The characteristics according to the intervention completion status were not different from those of the overall sample. The mean age of the participants was 27.75 years (SD 4.07). Most participants (103/120, 85.8%) identified as men, and the sample was racially/ethnically diverse. At baseline, majority (99/120, 82.5%) of the participants had recently received primary HIV care, yet this was more likely in those who completed the intervention than in those who did not (54/60, 90% vs 45/60, 75%; χ²₁=4.68, P=.03). More than half of the sample reported taking antiretroviral therapy (92/120, 76.7%) and having an undetectable viral load (65/120, 54.2%). The 6-month follow-up surveys were completed by 73.3% (88/120) of participants, and these participants were not characteristically different from the overall sample at baseline. GEE models indicated that participants had increased odds of viral suppression at 6 months as compared with baseline. No relevant additive or multiplicative interactions were noted on comparing outcome effects over time according to intervention completion.

CONCLUSIONS

Digital HIV care navigation fills a critical gap in public health and HIV care systems, making these systems more responsive and accountable to the needs of the most vulnerable individuals. Our intervention bridges the time between primary care visits with interactive, tailored, personalized, and peer-delivered social support; information; and motivational interviewing to scaffold behavioral change. This study is part of the next wave of system-informed mHealth intervention research that will offer potentially disruptive solutions to traditional in-person delivered interventions and improve the health of the most vulnerable individuals.

The Association Between Social Support, Violence, and Social Service Needs Among a Select Sample of Urban Adults in Baltimore City

Experiencing violence has been associated with negative health outcomes. The objectives of this study were to determine whether experiencing violence is associated increased support service needs and suboptimal general health indicators. In addition, we explore the relationship between these and perceived social support among a select sample of urban predominantly male adults in Baltimore City. A cross-sectional survey was conducted among 187 adults being seen in one of seven urban partner agencies participating in a parent HIV prevention and treatment demonstration project. Associations were examined using a multivariable logistic regression model, adjusting for the clinic site at which the client was being seen as well as age and gender identity. There was a significant amount of violence experienced by this population; 131 (72%) reported having seen someone be physically assaulted, and 89 (49%) had been physically assaulted without a weapon. Direct victimization from violence was associated with a threefold increased odds of needing housing and mental health/substance use services. Exposure to violence was associated with a threefold increase in needing housing and mental health/substance use services, and with sub-optimal health status. Perceived social support was associated with 30% decreased reports of experiencing violence. In conclusion, our select sample of urban adults report having experienced high rates of violence, and this is associated with increased support service needs as well as suboptimal perceived health status. Incorporating care for the effects of experiencing violence as well as social service needs are important in optimizing the health of urban populations.

Predictive Analytics for Retention in Care in an Urban HIV Clinic

Consistent medical care among people living with HIV is essential for both individual and public health. HIV-positive individuals who are ‘retained in care’ are more likely to be prescribed antiretroviral medication and achieve HIV viral suppression, effectively eliminating the risk of transmitting HIV to others. However, in the United States, less than half of HIV-positive individuals are retained in care. Interventions to improve retention in care are resource intensive, and there is currently no systematic way to identify patients at risk for falling out of care who would benefit from these interventions. We developed a machine learning model to identify patients at risk for dropping out of care in an urban HIV care clinic using electronic medical records and geospatial data. The machine learning model has a mean positive predictive value of 34.6% [SD: 0.15] for flagging the top 10% highest risk patients as needing interventions, performing better than the previous state-of-the-art logistic regression model (PPV of 17% [SD: 0.06]) and the baseline rate of 11.1% [SD: 0.02]. Machine learning methods can improve the prediction ability in HIV care clinics to proactively identify patients at risk for not returning to medical care.

Digital HIV Care Navigation for Young People Living With HIV in San Francisco, California: Feasibility and Acceptability Study

BACKGROUND

HIV continues to be a public health challenge adversely affecting youth and young adults, as they are the fastest-growing group of new HIV infections in the United States and the group with the poorest health outcomes among those living with HIV. HIV prevention science has turned to mobile health as a novel approach to reach and engage young people living with HIV (YPLWH) experiencing barriers to HIV care.

OBJECTIVE

This study aimed to assess the feasibility and acceptability of a text message-based HIV care navigation intervention for YPLWH in San Francisco. Health eNavigation is a 6-month text message-based HIV care navigation where YPLWH are connected to their own HIV care navigator through text messaging to improve engagement in HIV primary care. Digital HIV care navigation included delivery of the following through SMS text messaging: (1) HIV care navigation, (2) health promotion and education, (3) motivational interviewing, and (4) social support.

METHODS

We evaluated the feasibility and acceptability of a text message-based HIV care navigation intervention among YPLWH. We assessed feasibility using quantitative data for the overall sample (N=120) to describe participant text messaging activity during the intervention. Acceptability was assessed through semistructured, in-depth interviews with a subsample of 16 participants 12 months after enrollment. Interviews were audio-recorded, transcribed, and analyzed using grounded theory.

RESULTS

Overall, the text message-based HIV care navigation intervention was feasible and acceptable. The majority of participants exhibited medium or high levels of engagement (50/120 [41.7%] and 26/120 [21.7%], respectively). Of the majority of participants who were newly diagnosed with HIV, 63% (24/38) had medium to high engagement. Similarly, among those who were not newly diagnosed, 63% (52/82) had medium to high engagement. The majority of participants found that the intervention added value to their lives and improved their engagement in HIV care, medication adherence, and viral suppression.

CONCLUSIONS

Text message-based HIV care navigation is a potentially powerful tool that may help bridge the gaps for linkage and retention and improve overall engagement in HIV care for many YPLWH. Our results indicate that participation in text message-based HIV care navigation is both feasible and acceptable across pervasive structural barriers that would otherwise hinder intervention engagement.

Medical, Mental Health, and Social Service Linkage Predicts Better HIV Outcomes: A Network Analytic Approach

This study presents a conceptual and quantitative approach to assess service linkages among people living with HIV (PLWH). We use network analytic techniques to document linkages among service providers based on client reports of service utilization. Data are provided by a cohort study of 1012 PLWH in New York City interviewed up to 8 times from 2002 to 2015. Participants in each interview reported service needs, services received, and location of services for primary care, behavior health, case management, and housing, food, or other social services. Each reported clinic or agency was linked to entries in a database of medical and social service providers, which included details on organizational characteristics. Based on connections indicated by clients' reported referrals, service co-location within a single agency, or service site part of a larger parent organization, we constructed networks of linkages operationally defining which service areas were linked with others. Case management and primary care were services most commonly linked with other services. The most common pairing was case management and housing services. Individuals with more linkages in their care networks, as measured by average number of connections per provider, were associated with greater odds of adherence to antiretroviral medication and suppressed viral load. Further, higher levels of service linkage were associated with reduced emergency department visits and hospital admission rates. This study offers an innovative approach to analyzing linkages and outcomes from the perspective of service users in terms of their care experiences and provides insights into patient self-management of what are often multiple medical and support service needs. Study limitations include the use of data from a single urban setting and gaps in service reports.

Implementing a Digital HIV Care Navigation Intervention (Health eNav): Protocol for a Feasibility Study

BACKGROUND

Young racial and ethnic minority men who have sex with men (MSM) and trans women are disproportionately affected by HIV and AIDS in the United States. Unrecognized infection, due to a low uptake of HIV testing, and poor linkage to care are driving forces of ongoing HIV transmission among young racial and ethnic minority MSM and trans women. Internet and mobile technologies, in combination with social network-based approaches, offer great potential to overcome and address barriers to care and effectively disseminate interventions.

OBJECTIVE

We describe Health eNavigation (Health eNav), a digital HIV care navigation intervention that extends supportive care structures beyond clinic walls to serve youth and young adults living with HIV who are newly diagnosed, not linked to care, out of care, and not virally suppressed, at times when they need support the most.

METHODS

This study leverages ecological momentary assessments for a period of 90 days and uses person-delivered short message service text messages to provide participants with digital HIV care navigation over a 6-month period. We aim to improve engagement, linkage, and retention in HIV care and improve viral suppression. Digital HIV care navigation includes the following components: (1) HIV care navigation, (2) health promotion, (3) motivational interviewing, and (4) digital social support.

RESULTS

Recruitment began on November 18, 2016; enrollment closed on May 31, 2018. Intervention delivery ended on November 30, 2018, and follow-up evaluations concluded on October 31, 2019. In this paper, we present baseline sample characteristics.

CONCLUSIONS

We discuss real-world strategies and challenges in delivering the digital HIV care navigation intervention in a city-level, public health setting.
