Advancing Patient Navigation for HIV: Evaluating Models of Care for Housing and Employment.

People with HIV face challenges securing housing and employment. Patient navigation is an effective intervention that can improve the receipt of these services, which have been linked to better health outcomes. The purpose of this study was to assess implementation of patient navigation in diverse delivery settings. We also evaluated the relationship between these services and health outcomes among participants. Twelve sites in the United States (N = 1,082) implemented navigation using single or multiple navigator interventions to improve housing, employment, viral suppression, and retention in care. Sites included health departments, health centers, and AIDS service organizations (ASO). Client-level data were used to model relationships of interest. Across the 12 sites, regardless of model, housing (odds ratio (OR) = 1.18, p < .001), employment (OR = 1.09, p < .001) and retention in care (OR 1.11, p = .007) improved significantly over time; however, viral suppression did not (OR = 1.04, p = .120). Regardless of model of care, patient navigation improved housing, employment, and retention in care. This study demonstrated that while navigation supports people with HIV in securing housing and employment, models using a more intensive format worked best in specific settings. While most studies focus on unimodal strategies, this study builds on the evidence by examining how navigation models can be delivered to reduce barriers to care.

"They made me feel like I mattered": a qualitative study of how mobile crisis teams can support people experiencing homelessness.

BACKGROUND: Mobile crisis teams (MCTs) can be important alternatives to emergency medical services or law enforcement for low-acuity 911 calls. MCTs address crises by de-escalating non-violent situations related to mental health or substance use disorders and concurrent social needs, which are common among people experiencing homelessness (PEH). We sought to explore how an MCT in one city served the needs and supported the long- and short-term goals of PEH who had recently received MCT services. METHODS: We conducted 20 semi-structured interviews with service recipients of the Street Crisis Response Team, a new 911-dispatched MCT implemented in San Francisco in November 2020. In the weeks after their encounter, we interviewed respondents about their overall MCT experience and comparisons to similar services, including perceived facilitators and barriers to the respondent's self-defined life goals. We analyzed interview transcripts with thematic analysis to capture salient themes emerging from the text and organized within a social-ecological model. RESULTS: Nearly all respondents preferred the MCT model over traditional first responders, highlighting the team's person-centered approach. Respondents described the MCT model as effectively addressing their most immediate needs (e.g., food), short-term relief from the demands of homelessness, acute mental health or substance use symptoms, and immediate emotional support. However, systemwide resource constraints limited the ability of the team to effectively address longer-term factors that drive crises, such as solutions to inadequate quality and capacity of current housing and healthcare systems and social services navigation. CONCLUSIONS: In this study, respondents perceived this MCT model as a desirable alternative to law enforcement and other first responders while satisfying immediate survival needs. To improve MCT's effectiveness for PEH, these teams could collaborate with follow-up providers capable of linking clients to resources and services that can meet their long-term needs. However, these teams may not be able to meaningfully impact the longstanding and complex issues that precipitate crises among PEH in the absence of structural changes to upstream drivers of homelessness and fragmentation of care systems.

HIV-1 Incidence, Adherence, and Drug Resistance in Individuals Taking Daily Emtricitabine/Tenofovir Disoproxil Fumarate for HIV-1 Pre-Exposure Prophylaxis: Pooled Analysis From 72 Global Studies.

BACKGROUND: Oral pre-exposure prophylaxis (PrEP) with emtricitabine/tenofovir disoproxil fumarate (F/TDF) has high efficacy against HIV-1 acquisition. Seventy-two prospective studies of daily oral F/TDF PrEP were conducted to evaluate HIV-1 incidence, drug resistance, adherence, and bone and renal safety in diverse settings. METHODS: HIV-1 incidence was calculated from incident HIV-1 diagnoses after PrEP initiation and within 60 days of discontinuation. Tenofovir concentration in dried blood spots (DBS), drug resistance, and bone/renal safety indicators were evaluated in a subset of studies. RESULTS: Among 17,274 participants, there were 101 cases with new HIV-1 diagnosis (0.77 per 100 person-years; 95% CI 0.63-0.94). In 78 cases with resistance data, 18 (23%) had M184I or V, one (1.3%) had K65R, and three (3.8%) had both mutations. In 54 cases with tenofovir concentration data from DBS, 45 (83.3%), 2 (3.7%), 6 (11.1%), and 1 (1.9%) had average adherence of <2, 2-3, 4-6, and ≥7 doses/week, respectively, and the corresponding incidence was 3.9 (95% CI 2.9-5.3), 0.24 (0.060-0.95), 0.27 (0.12-0.60), and 0.054 (0.008-0.38) per 100 person-years. Adherence was low in younger participants, Hispanic/Latinx and Black participants, cisgender women, and transgender women. Bone and renal adverse event incidence rates were 0.69 and 11.8 per 100 person-years, respectively, consistent with previous reports. CONCLUSIONS: Leveraging the largest pooled analysis of global PrEP studies to date, we demonstrate that F/TDF is safe and highly effective, even with less than daily dosing, in diverse clinical settings, geographies, populations, and routes of HIV-1 exposure.

HIV Preexposure Prophylaxis With Emtricitabine and Tenofovir Disoproxil Fumarate Among Cisgender Women.

Importance: Emtricitabine and tenofovir disoproxil fumarate (F/TDF) for HIV preexposure prophylaxis (PrEP) is highly effective in cisgender men who have sex with men (MSM) when adherence is high (>4 doses/week). Real-world effectiveness and adherence with F/TDF for PrEP in cisgender women is less well characterized. Objective: To characterize the effectiveness of F/TDF for PrEP and its relationship with adherence in cisgender women. Design, Setting, and Participants: Data were pooled from 11 F/TDF PrEP postapproval studies conducted in 6 countries that included 6296 cisgender women aged 15 to 69 years conducted from 2012 to 2020. HIV incidence was evaluated according to adherence level measured objectively (tenofovir diphosphate concentration in dried blood spots or tenofovir concentration in plasma; n = 288) and subjectively (electronic pill cap monitoring, pill counts, self-report, and study-reported adherence scale; n = 2954) using group-based trajectory modeling. Exposures: F/TDF prescribed orally once a day. HIV incidence was analyzed in subgroups based on adherence trajectory. Main Outcomes and Measures: HIV incidence. Results: Of the 6296 participants, 46% were from Kenya, 28% were from South Africa, 21% were from India, 2.9% were from Uganda, 1.6% were from Botswana, and 0.8% were from the US. The mean (SD) age at PrEP initiation across all studies was 25 (7) years, with 61% of participants being younger than 25 years. The overall HIV incidence was 0.72 per 100 person-years (95% CI, 0.51-1.01; 32 incident HIV diagnoses among 6296 participants). Four distinct groups of adherence trajectories were identified: consistently daily (7 doses/week), consistently high (4-6 doses/week), high but declining (from a mean of 4-6 doses/week and then declining), and consistently low (less than 2 doses/week). None of the 498 women with consistently daily adherence acquired HIV. Only 1 of the 658 women with consistently high adherence acquired HIV (incidence rate, 0.13/100 person-years [95% CI, 0.02-0.92]). The incidence rate was 0.49 per 100 person-years (95% CI, 0.22-1.08) in the high but declining adherence group (n = 1166) and 1.27 per 100 person-years (95% CI, 0.53-3.04) in the consistently low adherence group (n = 632). Conclusions and Relevance: In a pooled analysis of 11 postapproval studies of F/TDF for PrEP among cisgender women, overall HIV incidence was 0.72 per 100 person-years; individuals with consistently daily or consistently high adherence (4-6 doses/week) to PrEP experienced very low HIV incidence.

eHealth-Enhanced Peer Navigation for Substance Use Treatment and HIV Prevention Service Linkage for Young Adults Surveilled by the Criminal Legal System: Protocol for a Pilot Randomized Trial Study.

BACKGROUND: In the United States, the proportion of criminal legal-involved (CLI) adults with a substance use disorder reaches 72%, and ~150,000 persons with HIV pass through a carceral setting annually, which represents 16% of the HIV-infected population nationally. Despite the high need for substance use treatment and HIV prevention services, few carceral settings successfully link CLI individuals to treatment upon release. Young adults represent 41.9% of the adults incarcerated in the United States and have the highest HIV incidence rates nationally. Peer patient navigation has successfully increased community-based care linkage for people living with HIV leaving jail; yet, peer-led navigation for HIV prevention among HIV-negative CLI populations is undeveloped and untested. eHealth approaches to substance use and HIV prevention services hold promise because they improve access to effective intervention services, particularly for younger people. OBJECTIVE: This paper describes a protocol for a pilot randomized controlled trial that aims to improve linkage to substance use treatment and HIV prevention services using peer navigation and a codeveloped eHealth technology adjunct. METHODS: The three aims of this study are to (1) adapt an existing evidence-based navigator model and incorporate codeveloped eHealth technology to refer and link young adults (18 to 29 years) surveilled by the criminal legal system to substance use and pre-exposure prophylaxis (PrEP) services; (2) refine and test the intervention with criminal legal-involved young adults (CLI-YAs); and (3) assess the feasibility, acceptability, and impact of the intervention. Data to inform the intervention will be collected via system partner interviews (n=4) and focus groups with CLI-YAs (n=24). Next, an open trial (n=10) will be conducted. The intervention will be refined via interviews with participants and facilitators, and a randomized pilot trial (n=75) will be conducted to assess the feasibility, acceptability, and preliminary impact of the eHealth-enhanced navigation on substance use and PrEP services linkage. Exit interviews conducted with a subsample of intervention participants (n=10), the navigator (n=1), and system partners (n=4) will assess intervention acceptability and suggestions for improvement. A community of practice, a group of system partners with an interest in working toward solutions to common problems, will inform each phase of the study. RESULTS: The project is currently ongoing. The project was funded in September 2022. Internal review board approval was received on March 21, 2022. The first results from early study aims are expected to be published in 2025. CONCLUSIONS: This study provides an opportunity to reduce HIV acquisition and improve access to substance use treatment in a systemically marginalized group: young CLI-YAs. The results will contribute to the development and testing of a future multilevel randomized controlled trial. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/54815.

A Peer-to-Peer Collaborative Learning Approach for the Implementation of Evidence-Informed Interventions to Improve HIV-Related Health Outcomes.

The nationwide scale-up of evidence-based and evidence-informed interventions has been widely recognized as a crucial step in ending the HIV epidemic. Although the successful delivery of interventions may involve intensive expert training, technical assistance (TA), and dedicated funding, most organizations attempt to replicate interventions without access to focused expert guidance. Thus, there is a grave need for initiatives that meaningfully address HIV health disparities while addressing these inherent limitations. Here, the Health Resources and Services Administration HIV/AIDS Bureau (HRSA HAB) initiative Using Evidence-Informed Interventions to Improve HIV Health Outcomes among People Living with HIV (E2i) piloted an alternative approach to implementation that de-emphasized expert training to naturalistically simulate the experience of future HIV service organizations with limited access to TA. The E2i approach combined the HAB-adapted Institute for Healthcare Improvement's Breakthrough Series Collaborative Learning Model with HRSA HAB's Implementation Science Framework, to create an innovative multi-tiered system of peer-to-peer learning that was piloted across 11 evidence-informed interventions at 25 Ryan White HIV/AIDS Program sites. Four key types of peer-to-peer learning exchanges (i.e., intervention, site, staff role, and organization specific) took place at biannual peer learning sessions, while quarterly intervention cohort calls and E2i monthly calls with site staff occurred during the action periods between learning sessions. Peer-to-peer learning fostered both experiential learning and community building and allowed site staff to formulate robust site-specific action plans for rapid cycle testing between learning sessions. Strategies that increase the effectiveness of interventions while decreasing TA could provide a blueprint for the rapid uptake and integration of HIV interventions nationwide.

Impact of San Francisco's New Street crisis response Team on Service use among people experiencing homelessness with mental and substance use disorders: A mixed methods study protocol.

Mobile crisis services for people experiencing distress related to mental health or substance use are expanding rapidly across the US, yet there is little evidence to support these specific models of care. These new programs present a unique opportunity to expand the literature by utilizing implementation science methods to inform the future design of crisis systems. This mixed methods study will examine the effectiveness and acceptability of the Street Crisis Response Team (SCRT), a new 911-dispatched multidisciplinary mobile crisis intervention piloted in San Francisco, California. First, using quantitative data from electronic health records, we will conduct an interrupted time series analysis to quantitatively examine the impacts of the SCRT on people experiencing homelessness who utilized public behavioral health crisis services in San Francisco between November 2019 and August 2022, across four main outcomes within 30 days of the crisis episode: routine care utilization, crisis care reutilization, assessment for housing services, and jail entry. Second, to understand its impact on health equity, we will analyze racial and ethnic disparities in these outcomes prior to and after implementation of the SCRT. For the qualitative component, we will conduct semi-structured interviews with recipients of the SCRT's services to understand their experiences of the intervention and to identify how the SCRT influenced their health-related trajectories after the crisis encounter. Once complete, the quantitative and qualitative findings will be further analyzed in tandem to assist with more nuanced understanding of the effectiveness of the SCRT program. This evaluation of a novel mobile crisis response program will advance the field, while also providing a model for how real-world program implementation can be achieved in crisis service settings.

"It Comes in Steps and Stages": Experiences of People Living with HIV in Achieving Employment.

People living with HIV who are seeking jobs experience unique barriers to obtaining employment at the individual, group, and community levels. Traditional employment assistance programs can provide support but may not be tailored to some people living with HIV who often experience barriers to work related to their social needs (such as housing instability) or their lack of consistent engagement in the workforce. To understand how people living with HIV return to work, in-depth interviews were conducted with 43 participants enrolled in interventions coordinating HIV care with housing and employment services at eight sites across the US. Four themes emerged on strategies to increase employment: (1) assessing and responding to employment needs that align with their socio-economic environment; (2) using social networks among family and friends for referrals and support; (3) engaging with navigators who are able to connect clients to skills building opportunities and job resources; and (4) addressing the system barriers such as helping with unmet basic needs (e.g. transportation), finding employers who can accommodate workers with income limits associated with public benefits, and helping immigrants, transgender individuals, and people experiencing homelessness secure legal documentsthat facilitate entry into employment by reducing stigmatized identities.

Rapid start antiretroviral therapies for improved engagement in HIV care: implementation science evaluation protocol.

BACKGROUND: In 2020, the Health Resources and Services Administration's HIV/AIDS Bureau funded an initiative to promote implementation of rapid antiretroviral therapy initiation in 14 HIV treatment settings across the U.S. The goal of this initiative is to accelerate uptake of this evidence-based strategy and provide an implementation blueprint for other HIV care settings to reduce the time from HIV diagnosis to entry into care, for re-engagement in care for those out of care, initiation of treatment, and viral suppression. As part of the effort, an evaluation and technical assistance provider (ETAP) was funded to study implementation of the model in the 14 implementation sites. METHOD: The ETAP has used implementation science methods framed by the Dynamic Capabilities Model integrated with the Conceptual Model of Implementation Research to develop a Hybrid Type II, multi-site mixed-methods evaluation, described in this paper. The results of the evaluation will describe strategies associated with uptake, implementation outcomes, and HIV-related health outcomes for patients. DISCUSSION: This approach will allow us to understand in detail the processes that sites to implement and integrate rapid initiation of antiretroviral therapy as standard of care as a means of achieving equity in HIV care.

HIV Disclosure Practices to Family Among Mexican and Puerto Rican Sexual Minority Men with HIV in the Continental USA: Intersections of Sexual Orientation and HIV Stigma.

Disclosing a seropositive HIV status still is a complex process of assessing the risks, benefits, and potential personal and interpersonal outcomes associated with disclosure, such as stigma, rejection, or emotional support. We examined HIV disclosure practices to family and intersectional stigma related to HIV and sexual orientation among Latino sexual minority men (LSMM) of Mexican and Puerto Rican origin with HIV in the continental USA. Guided by Framework Analysis, we present data from 54 interviews with 33 LSMM participants in HIV care engagement interventions, and 21 project staff implementing the interventions. LSMM disclosed their HIV status to family seeking support. They applied stigma management techniques to manage the information communicated to family about their HIV status, including selective disclosure to some family members, conveying strategic information about the significance of having HIV, non-disclosure, or partial disclosure, silence and deceptions. LSMM HIV disclosure practices to family encompassed appraisals of intersectional stigma related to their sexual orientation and HIV, assessing the potential outcomes of disclosure, and the preservation of family ties.

Key Elements and Mechanisms of a Peer-Support Intervention to Reduce Loneliness and Isolation among Low-Income Older Adults: A Qualitative Implementation Science Study.

This paper describes the evaluation of a longitudinal peer-support program developed to address loneliness and isolation among low-income, urban community-dwelling older adults in San Francisco. Our objective was to determine barriers, challenges, and successful strategies in implementation of the program. In-depth qualitative interviews with clients (n = 15) and peers (n = 6) were conducted and analyzed thematically by program component. We identified barriers and challenges to engagement and outlined strategies used to identify clients, match them with peers, and provide support to both peers and clients. We found that peers played a flexible, non-clinical role and were perceived as friends. Connections to community resources helped when clients needed additional support. We also documented creative strategies used to maintain inter-personal connections during the COVID-19 pandemic. This study fills a gap in understanding how a peer-support program can be designed to address loneliness and social isolation, particularly in low-income, urban settings.

Addressing Racism's Role in the US HIV Epidemic: Qualitative Findings From Three Ending the HIV Epidemic Prevention Projects.

BACKGROUND: Racist socio-political and economic systems in the United States are root causes of HIV disparities among minoritized individuals. However, within HIV implementation science literature, there is scarce empirical research on how to effectively counter racism. This article names racism and White supremacy as key challenges to the success of the Ending the HIV Epidemic (EHE) initiative and delineates opportunities to integrate anti-racism into HIV interventions. METHODS: Formative data were synthesized from 3 EHE studies in California, North Carolina, and South Carolina. Each study engaged with community stakeholders to inform pre-exposure prophylaxis interventions. Key informant interviews and focus groups were used to query individuals-including Black individuals-about implementation challenges. Although racism was not an a priori focus of included studies, discourse on race and racism emerged as key study findings from all projects. RESULTS: Across diverse stakeholder groups and EHE locales, participants described racism as a threat to the success of the EHE initiative. Institutional and structural racism, intersectional stigma, and maltreatment of minoritized individuals within healthcare systems were cited as challenges to pre-exposure prophylaxis scale-up. Some recommendations for addressing racism were given-yet these primarily focused on the individual level (eg, enhanced training, outreach). CONCLUSIONS: EHE implementation scientists should commit to measurable anti-racist actions. To this end, we present a series of recommendations to help investigators evaluate the extent to which they are taking actionable steps to counter racism to improve the adoption, implementation, and real-world impact of EHE interventions for people of color.

Supporting Community Partners in Reducing HIV-Related Health Disparities: Technical Assistance Across a Spectrum of Intensity.

The HIV epidemic remains a public health threat in the U.S., and the dissemination and implementation of evidence-based prevention and care programs are critical to addressing significant HIV health disparities. The provision of technical assistance (TA) to program providers and evaluators is key for uptake of these programs. The University of California San Francisco Prevention Research Center (UCSF PRC) model for TA delivery uses topics and strategies adapted to address HIV health disparities for a global audience. This model specifically matches TA requests to a TA provider who has expertise in that area upon receiving a request through various communication channels. Areas of expertise include research methods, community engagement strategies, interventions, and Implementation Sciences. Our evaluation of diverse TA services indicates that on-demand TA is effective for light-touch requests and well-suited for moderate to intensive requests. The model is a promising, broad-reaching, and responsive alternative for providing TA to a multitude of HIV workforce recipients.

Outcomes from the Adaptation of an Evidence-Based Peer Linkage & Re-Engagement Intervention for Women of Color with HIV in Three Urban Clinics.

Peer interventions have demonstrated efficacy with improving HIV health outcomes. Yet, little is known about factors associated with their uptake into the clinic setting. Three urban sites in the US were funded to adapt, implement and evaluate a peer intervention to improve HIV health outcomes for 173 out of care and newly diagnosed women of color. Peers worked with cis and transgender women of color for four months to achieve the goals of linkage and retention in HIV case management and medical care. Results were 96% of women were linked to medical care, 73% were retained in care and 81% were virally suppressed post 12 months. The average duration of the peer intervention was seven months. Women who received four peer encounters had a 10% increase in retention in care and viral suppression. The findings highlight key elements such as dose and duration of client interaction for peer staff as part of the health care team.

Examining the Impact of the Golden Compass Clinical Care Program for Older People with HIV: A Qualitative Study.

The combined burden of geriatric conditions, comorbidities, and HIV requires a model of HIV care that offers a comprehensive clinical approach with people 50 years or older with HIV. Golden Compass is an outpatient, multidisciplinary HIV-geriatrics program with an onsite HIV geriatrician, cardiologist, pharmacist, and social worker, offering specialist referrals, care navigation, and classes on improving functional status and cognition. Participants (13 patients and 11 primary care providers) were recruited using a non-probability sampling method to participate in semi-structured interviews on the perceived impact of Golden Compass on care delivered to older people with HIV. Interviews were transcribed verbatim and framework analysis used to analyze the transcripts. The perceived impacts of Golden Compass by patients and providers were organized by the Compass points (Northern: Heart and Mind, Eastern: Bones and Strength, Southern: Navigation and Network, Western: Dental, Hearing, and Vision). Overall, patients valued the focus on functional health and whole-person care, leading to greater trust in the ability of providers. Providers gained new skills through the geriatrics, cardiology and/or pharmacist consultations. The HIV-geriatrics specialty approach of Golden Compass improved functional ability and quality of life for older adults with HIV. Few integrated care programs for older people with HIV have been evaluated. This study adds to the limited literature demonstrating high patient and provider satisfaction with a HIV-care model that incorporated principles of geriatric medicine emphasizing a comprehensive approach to sustaining functional ability and improving quality of life.

Exploring the Shift From HIV Pre-exposure Prophylaxis Awareness to Uptake Among Young Gay and Bisexual Men.

Introduction: HIV pre-exposure prophylaxis (PrEP) in the form of a daily oral medication is highly effective at preventing HIV. In the United States, awareness about PrEP has steadily increased over time among individuals vulnerable to HIV, however awareness has not translated into widescale uptake. Estimates are that fewer than 20% of 1.2 million Americans for whom PrEP is indicated are utilizing it. We sought to understand how individuals moved from PrEP awareness to PrEP utilization. Methods: We conducted a series (n = 31) of in-depth interviews with young people, predominantly gay and bisexual men, ages 18-29 years old between February 2015 and January 2016, as part of the evaluation of a multi-year demonstration project funded to test innovative approaches to improve sexual health outcomes and curb the HIV epidemic in California. Interviews were audio-recorded and transcribed verbatim. We conducted a thematic analysis. Results: We present a continuum of PrEP awareness that spans three phases-basic, moderate and advanced. Participants rarely reported becoming well-informed about PrEP over the course of an initial exposure to PrEP information. Learning occurred after multiple exposures to PrEP information through numerous intersecting forms, messengers and formal and informal communication channels. Positively framed messages delivered by formal messengers emphasizing PrEP as a sensible HIV prevention strategy and explicitly communicating a regard for sexual wellness were overwhelmingly persuasive and facilitated movement to the advanced awareness phase. Once participants reached the advanced phase of PrEP awareness, uptake was possible. Conclusions: Our analysis provides insights into how PrEP awareness led to PrEP uptake among young gay and bi-sexual men. Building demand among those in the basic awareness phase took longer than those in the moderate phase. Individuals involved in formal and informal PrEP education can set reasonable expectations about whether, when and how eventual uptake may occur when keeping the continuum of PrEP awareness framework in mind. Many young, gay and bi-sexual male prospective PrEP users will benefit from positively framed messages that emphasize personal well-being, including social, sexual and emotional benefits of PrEP use.

Association of Insurance Status With Emergent Versus Nonemergent Hospital Encounters Among Adults With Congenital Heart Disease.

Background Although the number of hospital visits has exponentially increased for adults with congenital heart disease (CHD) over the past few decades, the relationship between insurance status and hospital encounter type remains unknown. The purpose of this study was to evaluate the association between insurance status and emergent versus nonemergent encounters among adults with CHD ≥18 years old. Methods and Results We used California Office of Statewide Health Planning and Development Database from January 2005 to December 2015 to determine the trends of insurance status and encounters and the association of insurance status on encounter type among adults with CHD. A total 58 359 nonpregnancy encounters were identified in 6077 patients with CHD. From 2005 to 2015, the number of uninsured encounters decreased by 38%, whereas government insured encounters increased by 124% and private by 79%. Overall, there was a significantly higher proportion of emergent than nonemergent encounters associated with uninsured status (13.0% versus 1.8%; P<0.0001), whereas the proportion of nonemergent encounters associated with private insurance was higher than emergent encounters (35.8% versus 62.4%; P<0.0001). When individual patients with CHD became uninsured, they were ≈5 times more likely to experience an emergent encounter (P<0.0001); upon changing from uninsured to insured, they were significantly less likely to have an emergent encounter (P<0.001). After multivariate adjustment, uninsured status exhibited the highest odds of an emergent rather than nonemergent encounter compared with all other covariates (adjusted odds ratio, 9.20; 95% CI, 7.83-10.8; P<0.0001). Conclusions Efforts to enhance the ability to obtain and maintain insurance throughout the lifetime of patients with CHD might result in meaningful reductions in emergent encounters and a more efficient use of resources.

A peer intervention reduces loneliness and improves social well-being in low-income older adults: A mixed-methods study.

BACKGROUND: Evidence-based interventions addressing loneliness and social isolation are needed, including among low-income, community-dwelling older adults of diverse racial and ethnic backgrounds. Our objective was to assess the effect of a peer intervention in addressing loneliness, isolation, and behavioral health needs in this population. METHODS: We conducted a mixed-method, two-year longitudinal study of a peer-outreach intervention in 74 low-income older adults recruited via an urban senior center in San Francisco. Structured participant surveys were conducted at baseline and every 6 months for up to 2 years. Outcomes included loneliness (3-item UCLA loneliness scale), social interaction (10-item Duke index), self-perceived socializing barriers (range: 0-10), and depression (PHQ-2 screen). Data were analyzed using mixed-effects linear and logistic regression adjusted for age and gender. Qualitative, semi-structured interviews with participants (N = 15) and peers (N = 6) were conducted in English and Spanish and analyzed thematically. RESULTS: Participants were on average 71 years old (range: 59-96 years), with 58% male, 15% LGBT, 18% African American, 19% Latinx, 8% Asian, 86% living alone, and 36% with an ADL impairment. On average, 43 contact visits (IQR: 31-97 visits) between participants and peers occurred over the first year. Loneliness scores decreased by, on average, 0.8 points over 24 months (p = 0.015). Participants reported reduced depression (38%-16%, p < 0.001) and fewer barriers to socializing (1.5 fewer, p < 0.001). Because of the longitudinal relationship and matching of characteristics of peers to participants, participants reported strong feelings of kinship, motivations to reach out in other areas of life, and improved mood. CONCLUSION: Diverse older adults in an urban setting participating in a longitudinal peer program experienced reduced loneliness, depression, and barriers to socializing. Matching by shared backgrounds facilitated rapport and bonding between participants and peers.

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.
