RESUMO

The global COVID-19 pandemic has imposed unprecedented pressure on health systems and has interrupted public health efforts for other major health conditions, including HIV. It is critical to comprehensively understand how the pandemic has affected the delivery and utilization of HIV-related services and what are the effective strategies that may mitigate the negative impacts of COVID-19 and resultant interruptions. The current study thus aims to comprehensively investigate HIV service interruptions during the pandemic following a socioecological model, to assess their impacts on various outcomes of the HIV prevention and treatment cascade and to identify resilience resources for buffering impacts of interruptions on HIV treatment cascade outcomes. We will assess HIV service interruptions in South Carolina (SC) since 2020 using operational report data from Ryan White HIV clinics and HIV service utilization data (including telehealth use) based on statewide electronic health records (EHR) and cellphone-based place visitation data. We will further explore how HIV service interruptions affect HIV prevention and treatment cascade outcomes at appropriate geospatial units based on the integration of multi-type, multi-source datasets (e.g., EHR, geospatial data). Finally, we will identify institutional-, community-, and structural-level factors (e.g., resilience resources) that may mitigate the adverse impacts of HIV service interruptions based on the triangulation of quantitative (i.e., EHR data, geospatial data, online survey data) and qualitative (i.e., in-depth interviews with clinic leaders, healthcare providers, people living with HIV, and HIV clinic operational reports) data regarding health system infrastructure, social capital, and organizational preparedness. Our proposed research can lead to a better understanding of complicated HIV service interruptions in SC and resilience factors that can mitigate the negative effects of such interruptions on various HIV treatment cascade outcomes. The multilevel resilience resources identified through data triangulation will assist SC health departments and communities in developing strategic plans in response to this evolving pandemic and other future public health emergencies (e.g., monkeypox, disasters caused by climate change). The research findings can also inform public health policymaking and the practices of other Deep South states with similar sociocultural contexts in developing resilient healthcare systems and communities and advancing epidemic preparedness.

RESUMO

Aboriginal and Torres Strait Islander (hereafter Aboriginal) people are a priority population for HIV care in Australia; however, no HIV cascade exists for this population. We developed annual HIV cascades for 2010-2017 specific to Aboriginal peoples. By 2017, an estimated 595 Aboriginal people were living with HIV (PLWH); however, 14% remained undiagnosed. Cascade steps below global targets were: PLWH aware of their diagnosis (86%), and retention in care (81% of those who had received any care in previous two years in a sentinel network of clinics). For people retained in care, treatment outcomes surpassed global targets (92% receiving treatment, 93% viral suppression). Increases occurred across all HIV cascade steps over time; however, the least improvement was for retention in care, while the greatest improvement was achieving viral suppression. The HIV cascade for Aboriginal peoples highlights both gaps and strengths in the Australian HIV care system, and importantly highlights where potential interventions may be required to achieve the global UNAIDS targets.

RESUMO

The study objective was to explore the impact of COVID-19 pandemic restrictions on the clinics' ability to provide continuous healthcare services to youth (15-24 years) living with HIV (YLWH). One focused semi-structured interview was conducted with each HIV clinic site-resulting in ten interviews. Data were analyzed using thematic analysis techniques assisted by NVIVO coding software and themes indicating barriers and facilitators to providing uninterrupted healthcare were elicited. Six themes were identified that affected the care continuum of YLWH: Timeframe of clinic preparation to address COVID-19 restrictions; impact on treatment cascade monitoring data; impact on patient care; impact on staff and services offered; software use and virtual visits; community impact. With careful planning and preparation, clinics were able to successfully implement a process of care that adapted to COVID-19 restrictions. Guidance is provided on how healthcare facilities can effectively incorporate strategies to provide continued services during pandemics and natural disasters.

RESUMO

HIV/AIDS remains a looming presence in public health across the world, particularly in Sub-Saharan Africa. The HIV Care Cascade hinges on testing and knowledge of HIV status. Though significant advances have been made in diagnosing people living with HIV (PLHIV), limitations in understanding which strategies are best suited to certain regions or populations have contributed to the uneven distribution in the success of various HIV testing strategies. Here, we present a conceptual framework that outlines effective HIV testing strategies for four target groups. This framework is based on a systematic literature review of articles published from January 1st, 2008, to December 31st, 2019. The effectiveness of HIV testing strategies depends on various factors including the setting, type of test and service providers. Multiple strategies are needed to reach the UNAIDS target of 95% of individuals knowing their HIV status. Expansion of community-based approaches, self-testing and HIV testing services in antenatal care will further improve the state of HIV testing in Sub-Saharan Africa.

RESUMO

The HIV care continuum (HCC), comprised of five steps (screening, linkage to care, treatment initiation, retention, and viral suppression), is used to monitor treatment delivery to people living with HIV (PLWH). The HCC has primarily focused on large urban or metropolitan areas where the situation may differ from that in smaller cities. Three themes (i.e., knowledge, stigma, stability) that shaped HCC outcomes were identified from analysis of two qualitative studies involving HIV service providers, public health experts, and PLWH in smaller cities of southern New England. The findings suggest that enhancing HCC outcomes require a multiprong approach that targets both the individual and organizational levels and includes interventions to increase health literacy, staff communication skills, universal screening to assess patients' religiosity/spirituality and supplemental service needs. Interventions that further ensure patient confidentiality and the co-location and coordination of HIV and other healthcare services are particularly important in smaller cities.


RESUMEN: El cuidado continuo de VIH (HCC), constado de cinco etapas (pruebas, vinculación al cuidado, inico del tratamiento, retención, y supresión viral), se emplea para monitorizar la entrega de tratamientos a las personas que vivien con VIH (PLWH). El HCC ha enfocado principalmente en áreas grandes y urbanas o áreas metropolitanas, donde la situación podría ser diferente que la de las ciudades más pequeñas. Tres temas (i.e., conocimiento, estigma, estabilidad) que formaron los resultados de HCC fueron identificados con análisis de dos estudios cualitativos que involucraron los proveedores de servicios de VIH, expertos de la salud pública, y PLWH en ciudades más pequeñas en las partes sureñas de Nueva Inglaterra. Los hallazgos sugieren que la mejora de los resultados de HCC requiere un enfoque multidimensional que se dirigen a ambos niveles del individuo y organización, y que incluyen intervenciones para aumentar la alfabetización sanitaria, la habilidad de comunicación del personal, la prueba universal para evaluar la religiosidad/espiritualidad de los pacientes y la necesidad de servicios suplementarios. Intervenciones que aseguran aún más la confidencialidad de los pacientes y el co-ubicación y coordinación de los servicios de VIH y otras asistencias medicas son particularmente importantes en ciudades pequeñas.

RESUMO

Tajikistani migrants who work in Russia and acquire HIV seldom receive HIV treatment while in Russia. Barriers to engagement in the HIV care cascade were identified from in-depth, semi-structured interviews with purposefully sampled Tajikistani migrants (n = 34) with HIV who had returned from Russia. Data were analyzed using thematic analysis, drawing from Putnam's theory of social capital, showing how bridging and bonding social capital relate to poor engagement in HIV care. We identified three barriers to Tajikistani migrants' movement through the HIV care cascade: (1) Russia's migration ban on people with HIV interrupts social capital accumulation and prevents access to HIV treatment within Russia; (2) mistrust of authority figures, including healthcare providers, leads to avoiding treatment and harm-reduction services upon their return to Tajikistan; and (3) because of pervasive discrimination, Tajikistani migrants form weak social ties while in Russia, which exacerbates risk, including with Russian citizens, and deters engagement with HIV care. Deploying a treatment as prevention strategy and abolishing Russia's ban on people with HIV would improve both individual and public health.

RESUMO

Early antiretroviral therapy (ART) initiation is essential, but linkage to care following community-based services is often poor, and inadequately understood. This study examined factors influencing linkage to care following home-based HIV-testing services (HBHTS) in a hyper-endemic setting in South Africa. HBHTS was offered to participants (N = 10,236) enrolled in the second HIV Incidence Provincial Surveillance System survey (2015-2016), KwaZulu-Natal. Follow-up telephone surveys with 196 of the 313 individuals diagnosed HIV-positive through HBHTS were used to measure linkage to care (i.e., a clinic visit within 12 weeks) and ART-initiation. Among newly diagnosed individuals (N = 183), 55% linked to care, and 21% of those who were ART-eligible started treatment within 12 weeks. Linkage to care was less likely among participants who had doubted their HIV-diagnosis (aOR:0.46, 95%CI: 0.23-0.93) and more likely among participants who had disclosed their HIV-status (aOR:2.31, 95%CI: 1.07-4.97). Reasons for not linking to care included no time (61%), only wanting to start treatment when sick (48%), fear of side-effects (33%), and not believing the HIV-diagnosis (16%). Results indicate that HBHTS needs to be paired with targeted interventions to facilitate early linkage to care. Interventions are required to counter denial of HIV status and facilitate early linkage to care among healthier individuals.

RESUMO

BACKGROUND: Mozambique has a generalized HIV epidemic of 13.5% among the general population. Early modeling exercises in Mozambique estimate that key populations (KP), defined as men who have sex with men (MSM), female sex workers (FSW), and people who inject drugs (PWID), along with their partners account for about one third of all new infections. There is limited data describing the engagement of KP living with HIV in testing, care and treatment services. METHODS: We conducted a secondary data analysis of HIV-positive participants in the first Bio-behavioral Surveillance (BBS) surveys in Mozambique conducted 2011-2014 in order to assess service uptake and progress though the HIV treatment cascade among MSM, FSW, and PWID. Unweighted pooled estimates were calculated for each key population group. RESULTS: Among HIV-positive MSM, 63.2% of participants had ever received an HIV test, 8.8% were aware of their status, 6.1% reported having been linked to care, while 3.5% initiated ART and were currently on treatment. Of the HIV-infected FSW participants, 76.5% reported a previous HIV test and 22.4% were previously aware of their status. Linkage to care was reported by 20.1%, while 12.7% reported having initiated ART and 11.8% reported being on treatment at the time of the survey. Among HIV-infected PWID participants, 79.9% had previously received an HIV test, 63.2% were aware of their HIV status, and 49.0% reported being linked to care for their HIV infection. ART initiation was reported by 42.7% of participants, while 29.4% were on ART at the time of the survey. CONCLUSION: Among the three high risk populations in Mozambique, losses occurred throughout critical areas of service uptake with the most alarming breakpoint occurring at knowledge of HIV status. Special attention should be given to increasing HIV testing and linkage to ART treatment. Future surveys will provide the opportunity to monitor improvements across the cascade in line with global targets and should include viral load testing to guarantee a more complete picture of the treatment cascade.

RESUMO

OBJECTIVES: To quantify the HIV care cascade in a Cape Town sub-district to understand rates of linkage to and engagement in HIV care. METHODS: We used routinely collected data to reconstruct the treatment cascade for 8382 infected individuals who tested HIV + in 2012/2013. We obtained data on patient gender, year of initial HIV-positive test, age at testing and initial CD4 cell count and defined five stages of the HIV care cascade. We quantified attrition across cascade stages. RESULTS: Two-thirds of the sample (5646) were women. Men were older at time of first testing (36.5 vs. 31.3 years) and had more advanced HIV disease at diagnosis (298 vs. 404 CD4 cells/µL for women). The median duration of follow-up was 818 days. Among women, 90.5% attended an initial HIV care visit, 54.6% became eligible for antiretroviral therapy under local guidelines during follow-up, 49.3% initiated ART and 45.6% achieved a therapeutic response. Among men, 88.0% attended an initial HIV care visit, 67.4% became ART eligible during follow-up, 48.0% initiated ART and 42.4% achieved a therapeutic response. Approximately 3% of women and 5% of men died during follow-up. CONCLUSIONS: We were able to reconstruct the HIV treatment cascade using routinely collected data. In this setting, rates of engagement in care differ by gender in key stages of the cascade, with men faring worse than women at each cascade point. This highlights the need for interventions aimed at encouraging earlier testing, linkage, ART initiation and retention among men.


OBJECTIFS: Quantifier la cascade des soins du VIH dans un sous-district de Cape Town pour comprendre les taux de liaisons et d'engagement avec les soins du VIH. MÉTHODES: Nous avons utilisé des données collectées en routine pour reconstruire la cascade de traitement pour 8.382 personnes infectées, testées positives pour le VIH en 2012/13. Nous avons obtenu des données sur le sexe du patient, l'année du premier test positif pour le VIH, l'âge au moment de ce test et le nombre initial de cellules CD4, et avons défini cinq étapes de la cascade des soins du VIH. Nous avons quantifié l'attrition au long des étapes de la cascade. RÉSULTATS: Deux tiers de l'échantillon (5.646) étaient des femmes. Les hommes étaient plus âgés au moment du premier test (36,5 contre 31,3 ans) et avaient la maladie du VIH plus avancée au moment du diagnostic (298 contre 404 cellules CD4/µL pour les femmes). La durée médiane de suivi était de 818 jours. Parmi les femmes, 90,5% ont pris part à une première visite pour des soins du VIH, 54,6% sont devenues éligibles au traitement antirétroviral selon les directives locales au cours du suivi, 49,3% ont commencé une ART et 45,6% ont atteint une réponse thérapeutique. Chez les hommes, 88,0% ont pris part à une première visite pour les soins du VIH; 67,4% sont devenus éligibles à l'ART au cours du suivi, 48,0% ont commencé l'ART et 42,4% ont atteint une réponse thérapeutique. Environ 3% des femmes et 5% des hommes sont décédés au cours du suivi. CONCLUSIONS: Nous avons pu reconstruire la cascade de traitement du VIH en utilisant des données collectées en routine. Dans ce contexte, les taux d'engagement dans les soins diffèrent selon le sexe dans les étapes clés de la cascade, les hommes s'en tirant moins bien que les femmes à chaque point de la cascade. Cela met en évidence la nécessité d'interventions visant à encourager le dépistage précoce, la liaison, l'initiation de l'ART et la rétention chez les hommes.

RESUMO

Between 2001 and 2017, 108133 persons (45.7% of diagnosed cases) were initiated on anti-hepatitis C virus treatment in the Veterans Affairs healthcare system. In 2017, nonphysician clinicians accounted for 22.2% of prescriptions, infectious diseases specialists for 14.9%, and gastroenterologists/hepatologists for 10.3%. In the pre-direct-acting antiviral era, they accounted for 7.2%, 26.7%, and 11.6%, respectively.

RESUMO

We evaluated associations between levels of alcohol use and HIV care continuum components using national Veterans Aging Cohort Study data for all patients with HIV and AUDIT-C screening (2/1/2008-9/30/2014). Poisson regression models evaluated associations between alcohol use levels (non-drinking, low-, medium-, high-, and very high-level drinking) and: (1) engagement with care (documented CD4 cells/µl or viral load copies/ml labs), (2) ART treatment (≥ 1 prescription), and (3) viral suppression (HIV RNA < 500 copies/ml) within one year. Among 33,224 patients, alcohol use level was inversely associated with all care continuum outcomes (all p < 0.001). Adjusted prevalence of care engagement ranged from 77.8% (95% CI 77.1-78.4%) for non-drinking to 69.1% (66.6-71.6%) for high-level drinking. The corresponding range for ART treatment was 74.0% (73.3-74.7%) to 60.1% (57.3-62.9%) and for viral suppression was 57.3% (56.5-58.1%) to 38.3% (35.6-41.1%). Greater alcohol use is associated with suboptimal HIV treatment across the HIV care continuum.

RESUMO

Though housing instability is linked to poor HIV health outcomes, studies that assess the HIV treatment cascade by housing status are limited. Using data from a multi-site Retention in Care initiative we constructed HIV treatment cascades for participants (n = 463) of five grantee sites. We found no significant differences in viral suppression at follow-up among participants who were unstably housed at enrollment (49%) as compared to those who were stably housed at enrollment (54%). Among participants with available data at 6- or 12-month follow-up, 94% were engaged in care, 90% were retained in, 94% were on ART, and 71% had suppressed viral load. Some site-level differences were noted; at two of the sites participants who were stably housed were more likely to be retained in care and on ART. Overall, findings demonstrated that participants moved successfully through the HIV treatment cascade regardless of housing status at enrollment, suggesting that evidence-based support and services to help people living with HIV/AIDS can help mitigate barriers to engagement in care associated with lack of stable housing.

RESUMO

Young transgender women (YTW) are disproportionately affected by HIV, however, little is known about the factors associated with HIV infection and treatment engagement. We examined correlates of HIV infection and the steps of the HIV treatment cascade, specifically, being aware of their HIV infection, linked to care, on ART, and adherent to ART. We analyzed the baseline data of Project LifeSkills, a randomized control trial of sexually active YTW recruited from Chicago, Illinois and Boston, Massachusetts. We conducted multivariable Poisson regressions to evaluate correlates of HIV infection and the steps of the HIV treatment cascade. Nearly a quarter (24.7%) of YTW were HIV-infected. Among HIV-infected YTW, 86.2% were aware of their HIV status, 72.3% were linked to care, 56.9% were on ART, and 46.2% were adherent to ART. Having avoided healthcare due to cost in the past 12 months and not having a primary care provider were associated with suboptimal engagement in HIV care. Our results suggest that improving linkage and retention in care by addressing financial barriers and improving access to primary care providers could significantly improve health outcomes of YTW as well as reduce forward transmission of HIV.

RESUMO

Identifying and linking people to care soon after HIV infection could limit viral transmission and protect their health. This work aims at describing the continuum of care among recently HIV-infected people who inject drugs (PWID) and participated in an intervention in the context of an HIV outbreak in Athens, Greece. The Transmission Reduction Intervention Project (TRIP) conducted risk network-based contact tracing and screened people for recent HIV infection. A comprehensive approach with a case management component that aimed to remove barriers to accessing care was adopted. Follow-up data on antiretroviral treatment (ART) and HIV-RNA levels were obtained from HIV clinics. TRIP enrolled 45 recently HIV-infected PWID (80% male) with a median viral load at recruitment of 5.43 log10 copies/mL. Of the recently infected persons in TRIP, 87% were linked to care; of these, 77% started ART; and of those on ART, 89% achieved viral load <200 copies/mL. TRIP and its public health allies managed to get most of the recently HIV-infected PWID who were identified by the program into care and many of them onto ART. This resulted in very low HIV-RNA levels. Treatment as prevention can work if individuals are aided in overcoming difficulties in entry to, or attrition from care.

RESUMO

Linkage to care from mobile clinics is often poor and inadequately understood. This multimethod study assessed linkage to care and antiretroviral therapy (ART) uptake following ART-referral by a mobile clinic in Cape Town (2015/2016). Clinic record data (N = 86) indicated that 67% linked to care (i.e., attended a clinic) and 42% initiated ART within 3 months. Linkage to care was positively associated with HIV-status disclosure intentions (aOR: 2.99, 95% CI 1.13-7.91), and treatment readiness (aOR: 2.97, 95% CI 1.05-8.34); and negatively with good health (aOR: 0.35, 95% CI 0.13-0.99), weekly alcohol consumption (aOR: 0.35, 95% CI 0.12-0.98), and internalised stigma (aOR: 0.32, 95% CI 0.11-0.91). Following linkage, perceived stigma negatively affected ART-initiation. In-depth interviews (N = 41) elucidated fears about ART side-effects, HIV-status denial, and food insecurity as barriers to ART initiation; while awareness of positive ART-effects, follow-up telephone counselling, familial responsibilities, and maintaining health to avoid involuntary disclosure were motivating factors. Results indicate that an array of interventions are required to encourage rapid ART-initiation following mobile clinic HIV-testing services.

RESUMO

Background: HIV programmes are achieving significant scale, even as external financing plateaus. Maximising achievement from identification to viral suppression is key to epidemic control and reaching global 95-95-95 goals. Cost and technical efficiency analyses can help programs understand why losses occur along the cascade, which tactics prevent losses, and additional investments required for cost-efficient solutions.Methodology: The PEPFAR- and USAID-funded Health Policy Plus (HP+) project identified cascade failure points and interventions needed in six countries (Ghana, Indonesia, Kyrgyz Republic, Kenya, Tajikistan, Tanzania). Methods included secondary data analysis and expert interviews. HP+ estimated unit costs and effectiveness of tactics to model future costs and cascade outcomes across scenarios. Conclusions across countries are synthesised for overall best practices.Results: In Ghana, Indonesia, Tajikistan, and the Kyrgyz Republic, HIV identification strategies need to evolve to counter diminishing testing yields. Higher-yield testing modes may have higher costs per person tested, yet lower costs per person identified compared to previous strategies. In Kenya, investments in linkage and retention require additional funding, and will reduce the need for expensive loss-to-follow-up activities. In Tanzania, differentiated antiretroviral therapy can improve patient management while reducing facility-level costs.Conclusion: Results from diverse settings suggest that cost-efficiency analyses aimed at smart cascades will help countries identify and resolve reasons for poor outcomes. The analyses are predicated on contextual exploration of how interventions are linked, and should inform prioritisation and investment strategies. While improving the cascade often has incremental costs, it may be cost-efficient versus the long-term cost of poor outcomes.

The correlation between mental health and sexual risk behaviours for HIV infection remains largely unknown in low and middle income settings. The present study determined the prevalence of psychological distress (PD) in a sub-Saharan African population with a generalized HIV epidemic, and investigated associations with HIV acquisition risk and uptake of HIV services using data from a cross-sectional survey of 13,252 adults. PD was measured using the Shona Symptom Questionnaire. Logistic regression was used to measure associations between PD and hypothesized covariates. The prevalence of PD was 4.5% (95% CI 3.9-5.1%) among men, and 12.9% (95% CI 12.2-13.6%) among women. PD was associated with sexual risk behaviours for HIV infection and HIV-infected individuals were more likely to suffer from PD. Amongst those initiated on anti-retroviral therapy, individuals with PD were less likely to adhere to treatment (91 vs. 96%; age- and site-type-adjusted odds ratio = 0.38; 95% CI 0.15, 0.99). Integrated HIV and mental health services may enhance HIV care and treatment outcomes in high HIV-prevalence populations in sub-Saharan Africa.

RESUMO

HIV testing services are the gateway into HIV treatment and are critical for monitoring the epidemic. HIV testing is recommended at least annually in high-risk populations, including people who inject drugs (PWID). In Malaysia, the HIV epidemic is concentrated among PWID, but their adherence to testing recommendations and the proportion of HIV-positive PWID who are aware of their status remain unknown. We recruited 460 PWID in Greater Kuala Lumpur using respondent-driven sampling and conducted HIV testing. We examined past testing behaviors, estimating testing frequency, correlates of testing in the past 12 months, and the proportion of those living with HIV who were aware of their status. Results showed that most PWID living with HIV (90.4%, 95% CI: 83.6%-95.9%) were aware of their status. Among those never previously diagnosed with HIV, few had accessed HIV testing in the past 12 months (14.3%, 95% CI: 11.1%-18.0%). Prison (57.0%) and compulsory drug detention centers (36.1%) were the primary locations where PWID reported ever being HIV tested, and the main correlate of recent testing in regression was recent criminal justice involvement. Although awareness of HIV status may be high among PWID living with HIV in Kuala Lumpur, testing occurs primarily in prisons and compulsory drug detention centers, where it is involuntary and linkage to care is limited. A shift in HIV testing policy is needed to align health and human rights objectives, replacing mandatory testing with voluntary testing in settings where individuals can be rapidly linked to HIV care.

RESUMO

BACKGROUND: The exponential growth in the reach and development of new technologies over the past decade means that mobile technologies and social media play an increasingly important role in service delivery models to maximise HIV testing and access to treatment and care. This systematic review examines the impact of electronic and mobile technologies in medical care (eHealth) in the linkage to and retention of priority populations in the HIV treatment and care cascade, focussing on the Asia-Pacific region. METHODS: The review was informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement from the Cochrane Collaboration guidelines. Both grey and published scientific literature from five different databases were searched for all original articles in English published from 2010 to 2017. Studies conducted outside the Asia-Pacific region or not including HIV priority populations were excluded. The methodological quality of studies included in the review was assessed using the Quality Assessment Tool for Quantitative Studies. RESULTS: The database search identified 7309 records. Of the 224 peer-reviewed articles identified for full text review, 16 studies from seven countries met inclusion criteria. Six cross sectional studies found evidence to support the use of eHealth, via text messages, instant messaging, social media and health promotion websites, to increase rates of HIV testing and re-testing among men who have sex with men (MSM). Evidence regarding the efficacy of eHealth interventions to improve antiretroviral treatment (ART) adherence was mixed, where one randomised controlled trial (RCT) showed significant benefit of weekly phone call reminders on improving ART adherence. Three further RCTs found that biofeedback eHealth interventions that provided estimated ART plasma concentration levels, showed promising results for ART adherence. CONCLUSIONS: This review found encouraging evidence about how eHealth can be used across the HIV treatment and care cascade in the Asia-Pacific region, including increasing HIV testing and re-testing in priority populations as well as ART adherence. eHealth interventions have an important role to play in the movement towards the end of AIDS, particularly to target harder-to-reach HIV priority populations, such as MSM.

RESUMO

Background: The US National HIV/AIDS Strategy (NHAS) aims for 72% (90% diagnosed times 80% of those virally suppressed) viral suppression among persons with human immunodeficiency virus (HIV) by 2020. We examined the clinical and economic impact of reaching this target, in the general US population and among black men who have sex with men (MSM), the group with the highest HIV prevalence. Methods: Using a mathematical simulation, we project the 5- and 20-year clinical outcomes, costs, and incremental cost-effectiveness ratios for (1) Current Pace of detection, linkage, retention, and virologic suppression and (2) NHAS investments in expanded testing ($24-$74 per test) and adherence ($400 per person-year), calibrated to achieve 72% suppression by 2020. We examined alternative rates of testing, retention, and suppression and the efficacy and cost of adherence interventions. Results: Compared with Current Pace over 20 years, NHAS averted 280000 HIV transmissions (80000 in black MSM) and 199000 (45000) deaths and saved 2138000 (453000) years of life, while increasing costs by 23%. The incremental cost-effectiveness ratio for NHAS compared with Current Pace was $68900 per quality-adjusted life-year ($38300 for black MSM) and was most sensitive to antiretroviral therapy costs. Conclusions: Reaching NHAS targets would yield substantial clinical benefits and be cost-effective in both the general US and black MSM populations.
