"There's absolutely no downside to this, I mean, except community opposition:" A qualitative study of the acceptability of vending machines for harm reduction.

BACKGROUND: Vending machines for harm reduction (VMHR) are an innovative approach to deliver life-saving materials, information, and treatment for hard-to-reach populations, particularly for persons who inject drugs. The current study explores stakeholders' perspectives on the feasibility and acceptability of VMHR in Philadelphia. METHODS: From October 2021 to February 2022, we conducted 31 semi-structured interviews with potential end users, staff, and leadership at a local federally qualified health center, and community members. Trained coders extracted themes from interview transcripts across four key domains: materials and logistics, location, access, and community introduction. RESULTS: Interviewees from all stakeholder groups endorsed using VMHR to provide supplies for wound care, fentanyl test strips, naloxone, and materials to connect individuals to treatment and other services. Dispensing syringes and medications for opioid use disorder were commonly endorsed by health center staff but were more controversial among potential end users. Even within stakeholder groups, views varied with respect to where to locate the machines, but most agreed that the machine should be placed in the highest drug use areas. Across stakeholder groups, interviewees suggested several strategies to introduce and gain community acceptance of VMHR, including community education, one-on-one conversations with community members, and coupling the machine with safe disposal of syringes and information to link individuals to treatment. CONCLUSIONS: Stakeholders were generally receptive to VMHR. The current study findings are consistent with qualitative analyses from outside of the USA and contribute new ideas regarding the anticipated community response and best methods for introducing these machines to a community. With thoughtful planning and design, VMHR could be a feasible and acceptable modality to reduce death and disease transmission associated with the opioid and HIV epidemics in cities like Philadelphia.

Persistent Disparities in Smoking Rates Among PLWH Compared to the General Population in Philadelphia, 2009-2014.

Despite reductions in smoking rates in the general population, little is known about recent smoking trends among people living with HIV (PLWH). We compared the risk for smoking and temporal trends in smoking among PLWH and the general population in the Philadelphia metropolitan area between 2009 and 2014. We used weighted logistic regression to assess the relation between HIV and smoking, and examined temporal smoking trends. The adjusted odds ratio (OR) for smoking comparing PLWH to the general population was 1.80 (95% CI 1.55-2.09) after adjusting for socio-economic, demographic, and mental health diagnosis variables. Smoking prevalence decreased in both the PLWH and general populations during the study period, and we did not observe a significant difference in rates of decline between groups (P = 0.54). Despite overall progress in smoking cessation, a disparity persisted in smoking rates between PLWH and the general population, with and without adjustment for socio-economic, demographic, and mental health variables. Further research is needed to understand the mechanisms linking HIV and tobacco use in order to inform public health efforts to reduce smoking among PLWH.

Understanding the Intersection of Behavioral Risk and Social Determinants of Health and the Impact on an Outbreak of Human Immunodeficiency Virus Among Persons Who Inject Drugs in Philadelphia.

BACKGROUND: In 2018, Philadelphia identified an outbreak of new human immunodeficiency virus (HIV) infections among persons who inject drugs (PWID). Although conventional HIV surveillance systems capture individual-level behavioral risk, they are not able to capture the social and environmental factors contributing to rapid transmission. METHODS: HIV surveillance data were used to assess demographic, clinical, and behavioral factors for PWID with HIV diagnosed during 2017 and 2018. Social factors such as homelessness, disruption of encampments, and trends in sexual behaviors, drug use and syringe availability among PWID were captured through National HIV Behavioral Surveillance, routine hepatitis and sexually transmitted infection surveillance, and shelter and homeless outreach data. RESULTS: In 2018, there were 71 new infections among PWID, an increase of 115% since 2016. During this time, opioid overdose deaths peaked at 59 deaths per 100 000 persons, 85% of which involved the use of fentanyl. While overall reported homelessness increased, rates of those living unsheltered rose by 13%. The Philadelphia Department of Public Health identified increased injection frequency, encampment closures, and lack of syringe access as promoters of continued HIV transmission. CONCLUSION: The use of conventional surveillance methods only is inadequate for determining HIV risk during outbreaks. Incorporation of individual and aggregate level data on social and environmental determinants is necessary to develop effective outbreak response interventions.

Mental health, social support, and HIV-related sexual risk behaviors among HIV-negative adolescent sexual minority males: three U.S. cities, 2015.

We examined the association between mental health issues, social support, and HIV among adolescent sexual minority males (SMM), who are disproportionally affected by HIV. National HIV Behavioral Surveillance among Young Men Who Have Sex with Men (NHBS-YMSM) data among SMM aged 13-18 years were collected in three cities (Chicago, New York City, and Philadelphia). Separate log-linked Poisson regression models were used to estimate associations between mental health issues and social support (general and family), and 3 HIV-related sexual risk behavior outcomes: past-year condomless anal intercourse (CAI) with a male partner, past-year sex with ≥ 4 partners, and first vaginal or anal sex before age 13. Of 547 adolescent SMM, 22% reported ever attempting suicide and 10% reported past-month suicidal ideation. The majority (52%) reported depression and anxiety. Thirty-nine percent reported CAI, 29% reported ≥ 4 sex partners and 22% reported first sex before age 13. Ever attempting suicide, suicidal ideation, and depression and anxiety were associated with CAI. Separately, ever attempting suicide and lack of family support were associated with ≥ 4 sex partners. None of the mental health or support measures were associated with having sex before age 13. General social support was not associated with any sexual risk behaviors. Mental health issues are common among adolescent SMM and associated with sexual risk behaviors. Including mental health support in comprehensive HIV prevention for adolescent SMM could potentially reduce HIV risk in this population.

Factors Associated with Recent HIV Testing among Men Who Have Sex with Men in Philadelphia: a Cross-Sectional Analysis of the National Behavioral Surveillance System Survey.

The main objective of this study was to determine the demographic, geographic and socioeconomic characteristics of men who have sex with men (MSM) in Philadelphia that were associated with having a recent HIV test. We used data from the National HIV Behavioral Surveillance System (NHBS) surveys from 2011 and 2014 among MSM in Philadelphia, with the outcome of interest of having received an HIV test in the past twelve months. Of 1043 HIV-negative MSM, 70.2% had an HIV test. Multivariable analysis showed that seeing a medical provider (aOR: 1.73; p = .0039) or having heard of PrEP (aOR: 2.24; p < .0001) was associated with recent HIV testing. Those participants forty-five years of age or older (aOR 0.40, p = .0001) and those with Medicaid had lower rates of HIV testing (aOR 0.48, p = .002). Although over 80% of participants had seen a medical provider in the past year, only 50% had been offered an HIV test by a provider. Optimizing HIV testing through the expansion and increased awareness of PrEP, especially among older MSM, is critical. Further research is needed to delineate barriers that prevent MSM from utilizing medical providers for HIV testing and for those with Medicaid from receiving HIV testing.

High Human Immunodeficiency Virus Incidence and Prevalence and Associated Factors Among Adolescent Sexual Minority Males-3 Cities, 2015.

Background: Much has been written about the impact of human immunodeficiency virus (HIV) among young (13-24) sexual minority men (SMM). Evidence for concern is substantial for emerging adult (18-24 years) SMM. Data documenting the burden and associated risk factors of HIV among adolescent SMM (<18 years) remain limited. Methods: Adolescent SMM aged 13-18 years were recruited in 3 cities (Chicago, New York City, and Philadelphia) for interview and HIV testing. We used χ2 tests for percentages of binary variables and 1-way analysis of variance for means of continuous variables to assess differences by race/ethnicity in behaviors. We calculated estimated annual HIV incidence density (number of HIV infections per 100 person-years [PY] at risk). We computed Fisher's exact tests to determine differences in HIV prevalence by selected characteristics. Results: Of 415 sexually active adolescent SMM with a valid HIV test result, 25 (6%) had a positive test. Estimated annual HIV incidence density was 3.4/100 PY; incidence density was highest for blacks, followed by Hispanics, then whites (4.1, 3.2, and 1.1/100 PY, respectively). Factors associated with higher HIV prevalence included black race; ≥4 male partners, condomless anal sex, and exchange sex in the past 12 months; and a recent partner who was older, black, HIV-infected, or had ever been in jail or prison (P < .05). Conclusions: HIV-related risk behaviors, prevalence, and estimated incidence density for adolescent SMM were high, especially for minority SMM. Our findings suggest that initiating intervention efforts early may be helpful in combating these trends.

HIV care continuum outcomes of pregnant women living with HIV with and without depression.

Women living with HIV (WLWH) suffer from poor viral suppression and retention postpartum. The effect of perinatal depression on care continuum outcomes during pregnancy and postpartum is unknown. We performed a retrospective cohort analysis using HIV surveillance data of pregnant WLWH enrolled in perinatal case management in Philadelphia and evaluated the association between possible or definite depression with four outcomes: viral suppression at delivery, care engagement within three months postpartum, retention and viral suppression at one-year postpartum. Out of 337 deliveries (2005-2013) from 281 WLWH, 53.1% (n = 179) had no depression; 46.9% had either definite (n = 126) or possible (n = 32) depression during pregnancy. There were no differences by depression status across all four HIV care continuum outcomes in unadjusted and adjusted analyses. The prevalence of possible or definite depression was high among pregnant WLWH. HIV care continuum outcomes did not differ by depression status, likely because of supportive services and intensive case management provided to women with possible or definite depression.

Potential drivers of HIV acquisition in African-American women related to mass incarceration: an agent-based modelling study.

BACKGROUND: The United States has the highest incarceration rate in the world. Incarceration can increase HIV risk behaviors for individuals involved with the criminal justice system and may be a driver of HIV acquisition within the community. METHODS: We used an agent-based model to simulate HIV transmission in a sexual-contact network representing heterosexual African American men and women in Philadelphia to identify factors influencing the impact of male mass incarceration on HIV acquisition in women. The model was calibrated using surveillance data and assumed incarceration increased the number of sexual contacts and decreased HIV care engagement for men post-release. Incarceration of a partner increased the number of sexual contacts for women. We compared a counterfactual scenario with no incarceration to scenarios varying key parameters to determine what factors drove HIV acquisition in women. RESULTS: Setting the duration of male high-risk sexual behavior to two years post-release increased the number of HIV transmissions to women by more than 20%. Decreasing post-release HIV care engagement and increasing HIV acquisition risk attributable to sexually transmitted infections (STIs) also increased the number of HIV transmissions to women. Changing the duration of risk behavior for women, the proportion of women engaging in higher risk behavior, and the relative risk of incarceration for HIV-infected men had minimal impact. CONCLUSION: The mass incarceration of African American men can increase HIV acquisition in African American women on a population-level through factors including post-release high-risk behaviors, disruption of HIV care engagement among formerly incarcerated men, and increased STI prevalence. These findings suggest that the most influential points of intervention may be programs seeking to reduce male risk behaviors and promote HIV care engagement post-release, as well as STI testing and treatment programs for recently incarcerated men, as well as women with incarcerated partners.

Assessing the Impact of Perinatal HIV Case Management on Outcomes Along the HIV Care Continuum for Pregnant and Postpartum Women Living With HIV, Philadelphia 2005-2013.

To evaluate the impact of a Perinatal Medical Case Management (PCM) Program for women living with HIV (WLWH). Characteristics of pregnant and postpartum WLWH were compared between those who engaged in PCM and those who did not. Using secondary data collected from routine HIV surveillance, multivariable regression models were used to evaluate the association between PCM and four outcomes adapted from the HIV care continuum. In multivariable models, compared to WLWH not in PCM, participants (n = 448, 52.8%) were almost twice as likely to achieve HIV suppression before delivery (aOR 1.90 [1.33, 2.71], p = 0.0005); were more likely to be retained in HIV care 1 year postpartum (aOR 1.59 [1.17, 2.16], p = 0.0029); and were equally likely to engage in HIV care within 90-days of delivery (aOR 1.21 [0.88, 1.65], p = 0.236) and be virally suppressed 1 year postpartum (aOR 1.26 [0.90, 1.77], p = 0.178). PCM is an important intervention for preventing perinatal HIV transmission and closings gaps in the HIV care continuum for WLWH during pregnancy and postpartum.

Postpartum Engagement in HIV Care: An Important Predictor of Long-term Retention in Care and Viral Suppression.

BACKGROUND: Human immunodeficiency virus (HIV)-infected women are at risk of virologic failure postpartum. We evaluated factors influencing retention in care and viral suppression in postpartum HIV-infected women. METHODS: We conducted a retrospective cohort analysis (2005-2011) of 695 deliveries involving 561 HIV-infected women in Philadelphia. Multivariable logistic regression evaluated factors, including maternal age, race/ethnicity, substance use, antiretroviral therapy during pregnancy, timing of HIV diagnosis, previous pregnancy with HIV, adequacy of prenatal care, and postpartum HIV care engagement (≥ 1 CD4 count or viral load [VL] test within 90 days of delivery), associated with retention in care (≥ 1 CD4 count or VL test in each 6-month interval of the period with ≥ 60 days between tests) and viral suppression (VL ≤ 200 copies/mL at the last measure in the period) at 1 and 2 years postpartum. RESULTS: Overall, 38% of women engaged in HIV care within 90 days postpartum; with 39% and 31% retained in care and virally suppressed, respectively, at 1 year postpartum, and 25% and 34% retained in care and virally suppressed, respectively, at 2 years postpartum. In multivariable analyses, women who engaged in HIV care within 90 days of delivery were more likely to be retained (adjusted odds ratio [AOR], 11.38; 95% confidence interval [CI], 7.74-16.68) and suppressed (AOR, 2.60 [95% CI, 1.82-3.73]) at 1 year postpartum. This association persisted in the second year postpartum for both retention (AOR, 6.19 [95% CI, 4.04-9.50]) and suppression (AOR, 1.40 [95% CI, 1.01-1.95]). CONCLUSIONS: The prevalence of postpartum HIV-infected women retained in care and maintaining viral suppression is low. Interventions seeking to engage women in care shortly after delivery have the potential to improve clinical outcomes.

Health Outcomes of HIV-Infected People with Mental Illness.

Improving outcomes for people with HIV and mental illness will be critical to meeting the goals of the US National HIV/AIDS Strategy. In a retrospective analysis of the 2008-2010 cycles of the locally representative Philadelphia Medical Monitoring Project, we compared the proportions of HIV-infected adults with and without mental illness: (1) retained in care (≥2 primary HIV visits separated by ≥90 days in a 12-month period); (2) prescribed antiretroviral therapy (ART) at any point in a 12-month period; and (3) virally suppressed (HIV-1 RNA ≤200 copies/mL at the last measure in the 12-month period). Multivariable regression assessed associations between mental illness and the outcomes, adjusting for age, gender, race/ethnicity, insurance, alcohol abuse, injection drug use, CD4 count, and calendar year. Of 730 HIV-infected persons, representative of 9409 persons in care for HIV in Philadelphia, 49.0 % had mental illness. In adjusted analyses, there were no significant differences in retention (91.3 vs. 90.3 %; AOR 1.30, 95 % CI 0.63-2.56) and prescription of ART (83.2 vs. 88.7 %; AOR 0.79, 95 % CI 0.49-1.25) between those with and without mental illness. However, mentally ill patients were less likely to achieve viral suppression than those without mental illness (65.9 vs. 74.4 %; AOR 0.64, 95 % CI 0.46-0.90). These findings argue for the need to optimize ART adherence in this population.

Comparison of geographic methods to assess travel patterns of persons diagnosed with HIV in Philadelphia: how close is close enough?

Travel distance to medical care has been assessed using a variety of geographic methods. Network analyses are less common, but may generate more accurate estimates of travel costs. We compared straight-line distances and driving distance, as well as average drive time and travel time on a public transit network for 1789 persons diagnosed with HIV between 2010 and 2012 to identify differences overall, and by distinct geographic areas of Philadelphia. Paired t-tests were used to assess differences across methods, and analysis of variance was used to assess between-group differences. Driving distances were significantly longer than straight-line distances (p<0.001) and transit times were significantly longer than driving times (p<0.001). Persons living in the northeast section of the city traveled greater distances, and at greater cost of time and effort, than persons in all other areas of the city (p<0.001). Persons living in the northwest section of the city traveled farther and longer than all other areas except the northeast (p<0.0001). Network analyses that include public transit will likely produce a more realistic estimate of the travel costs, and may improve models to predict medical care outcomes.

Outcomes of HIV-infected patients receiving care at multiple clinics.

Receiving care at multiple clinics may compromise the therapeutic patient-provider alliance and adversely affect the treatment of people living with HIV. We evaluated 12,759 HIV-infected adults in Philadelphia, PA between 2008 and 2010 to determine the effects of using multiple clinics for primary HIV care. Using generalized estimating equations with logistic regression, we examined the relationship between receiving care at multiple clinics (≥ 1 visit to two or more clinics during a calendar year) and two outcomes: (1) use of ART and (2) HIV viral load ≤ 200 copies/mL for patients on ART. Overall, 986 patients (8 %) received care at multiple clinics. The likelihood of attending multiple clinics was greater for younger patients, women, blacks, persons with public insurance, and for individuals in their first year of care. Adjusting for sociodemographic factors, patients receiving care at multiple clinics were less likely to use ART (AOR = 0.62, 95 % CI 0.55-0.71) and achieve HIV viral suppression (AOR = 0.78, 95 % CI 0.66-0.94) than individuals using one clinic. Qualitative data are needed to understand the reasons for visiting multiple clinics.

Xylazine Use Among People Who Inject Drugs, Philadelphia 2022.

OBJECTIVES: Xylazine is commonly mixed with illicit opioids in Philadelphia, and potential associations with wound issues, infectious diseases, and overdoses are of public health concern. We used data from the National HIV Behavioral Surveillance Survey among persons who inject drugs (PWIDs) in Philadelphia to better identify individuals at risk and inform patients and clinicians about xylazine risk factors. METHODS: We compared characteristics of participants who reported using xylazine to those who reported not using xylazine in the past 12 months. Among those who reported xylazine use, we compared characteristics between people who prefer and did not prefer to use xylazine. RESULTS: In this sample of PWIDs, most prefer not to use xylazine, yet use is common. Compared with PWIDs not using xylazine, PWIDs who use xylazine were more likely to have recent homelessness, polysubstance use, overdose history, and hepatitis C virus infection ( P < 0.05 for all comparisons). Compared with concordant xylazine use, discordant xylazine use was associated with lower preference for fentanyl, heroin as the primary injection drug, and lower use of syringe service programs ( P < 0.05 for all comparisons). CONCLUSIONS: Public health entities should prioritize studying the use and health effects of xylazine in their jurisdictions and consider supporting point-of-care and drug-checking surveillance in addition to raising awareness of xylazine in the drug supply.

B-OK: A Visual and Tactile Tool for HIV Treatment Adherence Support in a United States Urban Center.

Lack of adherence to antiretroviral therapy (ART) and poor retention in care are significant barriers to ending HIV epidemics. Treatment adherence support (TAS) effectiveness may be constrained by limited awareness and understanding of the benefits of ART, particularly the concepts of treatment as prevention and Undetectable=Untransmittable (U=U), for which substantial knowledge gaps persist. We used mixed methods to evaluate a straightforward visual and tactile tool, the B-OK Bottles ("B-OK"), that incorporates human-centered design and behavioral economics principles and is designed to change and strengthen mental models about HIV disease progression and transmission. We enrolled 118 consenting adults living with HIV who were clients of medical case managers at one of four case management agencies in Philadelphia. All participants completed a pre-intervention survey, a B-OK intervention, and a post-intervention survey. A subset (N=52) also completed qualitative interviews before (N=20) or after (N=32) B-OK. Participants had a median age of 55 years (IQR 47-60), about two-thirds were male sex (N=77, 65%), nearly three-quarters identified as non-Hispanic Black (N=85, 72%), and almost all reported receiving ART (N=116, 98%). Exposure to B-OK was associated with improved awareness and understanding of HIV terminology, changes in attitudes about HIV treatment, and increased intention to rely on HIV treatment for transmission prevention. Insights from qualitative interviews aligned with the quantitative findings as respondents expressed a better understanding of U=U and felt that B-OK clearly explained concepts of HIV treatment and prevention. These findings provide a strong rationale to further evaluate the potential for B-OK to improve TAS for PLWH.

Impact of COVID-19 on People Living With HIV: Data From Five Medical Monitoring Project Sites, 2020-2022.

BACKGROUND: The COVID-19 pandemic disrupted global economic and healthcare systems. People living with HIV (PLWH) represent a marginalized and stigmatized population who may have been particularly impacted. The purpose of this analysis was to describe the impact of the COVID-19 pandemic on PLWH in the United States. SETTING: United States. METHODS: We analyzed surveys of behavioral and clinical characteristics of PLWH residing in 5 states that participated in the Medical Monitoring Project between 2020 and 2022. We described the impact of COVID-19 illness, testing, and diagnoses; receipt of medical care; social service access; employment; and preventive measures by project site and demographic characteristics. RESULTS: Unweighted data from 1715 PLWH were analyzed. A high proportion of PLWH had medical care disrupted by the pandemic; 31% of PLWH missed medical appointments, 26% missed routine laboratory test results, and 7% missed antiretroviral therapy doses. In total, 30% of PLWH reported losing wages and 19% reported difficulty in accessing social services. Overall, 88% reported receiving at least 1 dose of COVID-19 vaccine, but vaccine uptake was low among younger, Black, and Hispanic or Latina/o/x PLWH. CONCLUSIONS: This descriptive analysis reinforces previous findings that show that COVID-19 negatively impacted PLWH and their ability to obtain medical care. Additional efforts will be critical to ameliorating the longer-term impacts of COVID-19 on the health of PLWH and supporting PLWH through future pandemics and healthcare system disruptions.

Adolescent sexually transmitted infections and risk for subsequent HIV.

OBJECTIVES: We estimated the risk of HIV associated with sexually transmitted infection (STI) history during adolescence. METHODS: We retrospectively studied a cohort of adolescents (n = 75 273, born in 1985-1993) who participated in the Philadelphia High School STD Screening Program between 2003 and 2010. We matched the cohort to STI and HIV surveillance data sets and death certificates and performed Poisson regression to estimate the association between adolescent STI exposures and subsequent HIV diagnosis. RESULTS: Compared with individuals reporting no STIs during adolescence, adolescents with STIs had an increased risk for subsequent HIV infection (incidence rate ratio [IRR] for adolescent girls = 2.6; 95% confidence interval [CI] = 1.5, 4.7; IRR for adolescent boys = 2.3; 95% CI = 1.7, 3.1). Risk increased with number of STIs. The risk of subsequent HIV infection was more than 3 times as high among those with multiple gonococcal infections during adolescence as among those with none. CONCLUSIONS: Effective interventions that reduce adolescent STIs are needed to avert future STI and HIV acquisition. Focusing on adolescents with gonococcal infections or multiple STIs might have the greatest impact on future HIV risk.

Perspectives From Community-Based HIV Service Organization Leaders on Priorities in Serving Sexual and Gender Minority Populations.

Sexual and gender minority (SGM) populations experience discrimination and care-related barriers when seeking appropriate sexual health services. Using rapid assessment procedures we conducted site visits with 11 community-based HIV service agencies to identify priorities, assets, and needs related to serving SGM clients and assessed the alignment of these services with the city's local Ending the HIV Epidemic plan. We identified and mapped themes across agencies into the Consolidated Framework for Implementation Research domains of inner and outer settings: client-facing materials; priorities in serving SGM communities; SGM policies and protocols; collecting sexual orientation and gender identity data; training and education; and funding and scope of programs. Rapid assessment procedures can accelerate the collection and interpretation of data to help public health institutions and community partners make timely adaptations when implementing comprehensive and culturally humble sexual health services for SGM communities.

Costs and cost-effectiveness of a collaborative data-to-care intervention for HIV treatment and care in the United States.

INTRODUCTION: Data-to-care programmes utilize surveillance data to identify persons who are out of HIV care, re-engage them in care and improve HIV care outcomes. We assess the costs and cost-effectiveness of re-engagement in an HIV care intervention in the United States. METHODS: The Cooperative Re-engagement Control Trial (CoRECT) employed a data-to-care collaborative model between health departments and HIV care providers, August 2016-July 2018. The health departments in Connecticut (CT), Massachusetts (MA) and Philadelphia (PHL) collaborated with HIV clinics to identify newly out-of-care patients and randomize them to receive usual linkage and engagement in care services (standard-of-care control arm) or health department-initiated active re-engagement services (intervention arm). We used a microcosting approach to identify the activities and resources involved in the CoRECT intervention, separate from the standard-of-care, and quantified the costs. The cost data were collected at the start-up and recurrent phases of the trial to incorporate potential variation in the intervention costs. The costs were estimated from the healthcare provider perspective. RESULTS: The CoRECT trial in CT, MA and PHL randomly assigned on average 327, 316 and 305 participants per year either to the intervention arm (n = 166, 159 and 155) or the standard-of-care arm (n = 161, 157 and 150), respectively. Of those randomized, the number of participants re-engaged in care within 90 days in the intervention and standard-of-care arms was 85 and 70 in CT, 84 and 70 in MA, and 98 and 67 in PHL. The additional number of participants re-engaged in care in the intervention arm compared with those in the standard-of-care arm was 15 (CT), 14 (MA) and 31 (PHL). We estimated the annual total cost of the CoRECT intervention at $490,040 in CT, $473,297 in MA and $439,237 in PHL. The average cost per participant enrolled was $2952, $2977 and $2834 and the average cost per participant re-engaged in care was $5765, $5634 and $4482. We estimated an incremental cost per participant re-engaged in care at $32,669 (CT), $33,807 (MA) and $14,169 (PHL). CONCLUSIONS: The costs of the CoRECT intervention that identified newly out-of-care patients and re-engaged them in HIV care are comparable with other similar interventions, suggesting a potential for its cost-effectiveness in the US context.

The Cooperative Re-Engagement Controlled Trial (CoRECT): Durable Viral Suppression Assessment.

BACKGROUND: A collaborative, data-to-care strategy to identify persons with HIV (PWH) newly out-of-care, combined with an active public health intervention, significantly increases the proportion of PWH re-engaged in HIV care. We assessed this strategy's impact on durable viral suppression (DVS). METHODS: A multisite, prospective randomized controlled trial for out-of-care individuals using a data-to-care strategy and comparing public health field services to locate, contact, and facilitate access to care versus the standard of care. DVS was defined as the last viral load, the viral load at least 3 months before, and any viral load between the 2 were all <200 copies/mL during the 18-month postrandomization. Alternative definitions of DVS were also analyzed. RESULTS: Between August 1, 2016-July 31, 2018, 1893 participants were randomized from Connecticut (n = 654), Massachusetts (n = 630), and Philadelphia (n = 609). Rates of achieving DVS were similar in the intervention and standard-of-care arms in all jurisdictions (all sites: 43.4% vs 42.4%, P = 0.67; Connecticut: 46.7% vs 45.0%, P = 0.67; Massachusetts: 40.7 vs 44.4%, P = 0.35; Philadelphia: 42.4% vs 37.3%, P = 0.20). There was no association between DVS and the intervention (RR: 1.01, CI: 0.91-1.12; P = 0.85) adjusting for site, age categories, race/ethnicity, birth sex, CD4 categories, and exposure categories. CONCLUSION: A collaborative, data-to-care strategy, and active public health intervention did not increase the proportion of PWH achieving DVS, suggesting additional support to promote retention in care and antiretroviral adherence may be needed. Initial linkage and engagement services, through data-to-care or other means, are likely necessary but insufficient for achieving DVS for all PWH.
