The Impacts of HIV-Related Service Interruptions During the COVID-19 Pandemic: Protocol of a Mixed Methodology Longitudinal Study

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.

Self-Management Frameworks for Youth Living with Human Immunodeficiency Virus

HIV is now a chronic condition that can be managed. Adolescents and emerging adults represent a large proportion of new diagnoses, but struggle with many aspects of HIV-related self-management. Self-management of HIV is critical to maintaining health and involves retention in HIV care, medication adherence to achieve viral suppression, managing substance use, and sexual and general health-related behaviors. This article describes theoretic frameworks for HIV self-management as adapted for youth and reviews self-management interventions developed to improve health outcomes in youth living with HIV identified from a recent systematic review.

"Who are You and What are You Doing Here?": Social Capital and Barriers to Movement along the HIV Care Cascade among Tajikistani Migrants with HIV to Russia

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.

Effect of community-based interventions targeting female sex workers along the HIV care cascade in sub-Saharan Africa: a systematic review and meta-analysis

BACKGROUND

Female sex workers are extremely vulnerable and highly susceptible to being infected with human immunodeficiency virus. As a result, community-based targeted interventions have been recommended as one of the models of care to improve access to HIV services and continued engagement in care. We conducted a systematic review to (1) assess the effect of FSW-targeted community interventions on the improvement of HIV services access along the treatment cascade and (2) describe community-based interventions that positively affect continuation in HIV care across the HIV treatment cascade for FSWs in sub-Saharan Africa.

METHODS

We defined the 5 steps that make up the HIV care cascade and categorized them as outcomes, namely, HIV testing and diagnosis, linkage to care, receipt of ART, and achievement of viral suppression. We conducted a systematic search of randomized controlled trials, cohort, and cross-sectional studies done in sub-Saharan African countries and published from 2004 to 2020. The period was selected based on the time span within which ART was scaled up through widespread roll-out of comprehensive HIV programs in sub-Saharan Africa. We reviewed studies with data on the implementation of community interventions for any of the HIV care cascade stage. The data were analyzed using random effects meta-analysis where possible, and for the rest of the studies, data were synthesized using summary statistics.

RESULTS

The significant impact of the community interventions was observed on HIV testing, HIV diagnosis, and ART use. However, for HIV testing and ART use, the improvement was not sustained for the entire period of implementation. There were minimal interventions that had impact on HIV diagnosis, with only one community service delivery model showing significance. Generally, the interventions that had reasonable impact are those that implemented targeted and comprehensive package of HIV services provided at one location, and with unique strategies specific to each cascade stage.

CONCLUSIONS

The evidence brought forward from this review shows that the effect of community-based interventions varies across the different stages of HIV care cascade. A broad package of interventions including a combination of behavioral, biomedical, and structural, designed with specific strategies, unique to each cascade stage appears to be more effective, although information on long-term treatment outcomes and the extent to which FSWs remain engaged in care is sparse. There is need to conduct a further research to deepen the assessment of the effectiveness of community-based interventions on HIV care cascade for FSWs. This will enhance identification of evidence-based optimal interventions that will guide effective allocation of scarce resources for strategies that would have a significant impact on HIV service delivery.

The HIV Care Continuum in Small Cities of Southern New England: Perspectives of People Living with HIV/AIDS, Public Health Experts, and HIV Service Providers

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.

Low engagement in HIV services and progress through the treatment cascade among key populations living with HIV in Mozambique: alarming gaps in knowledge of status

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.

Scaling up HIV viral load monitoring in Manicaland, Zimbabwe: challenges and opportunities from the field

Background

Demand for viral load (VL) monitoring is expected to increase; however, implementation of the multifaceted VL testing poses numerous challenges. We report experiences from Médecins Sans Frontiéres (MSF) and partners in the scale-up of HIV VL in collaboration with the Ministry of Health and Child Care (MoHCC) of Zimbabwe.

Methods

A retrospective data review of routine reports from MSF-supported health facilities in Manicaland Province (Zimbabwe) was conducted. These secondary aggregate data were triangulated, and emerging themes of lessons learnt from VL monitoring were shared.

Results

A VL testing coverage of 63% (5966/9456) was achieved among the 40 health facilities, together with a switch rate to second-line antiretroviral therapy (ART) of 46.4% (108/233). The key enablers to scaling-up the VL monitoring were well-equipped and supported VL laboratories, the operationalisation of the on-the-job clinical mentoring and systematic weaning off of better performing health facilities. Concerted efforts from different implementing partners and funders in the HIV programme, and close collaboration with MoHCC were pivotal.

Conclusion

Our experience indicates that clinical mentoring is effective, and resulted in high VL testing coverage and up-skilling primary health care workers in VL monitoring. Attention must be focused on innovations for improving VL result utilisation, especially the identification and management of patients who fail ART.

Quantifying the HIV treatment cascade in a South African health sub-district by gender: retrospective cohort study

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.

The HIV treatment cascade in people living with HIV in Iran in 2014: Mixed-method study to measure losses and reasons

The study assessed the HIV treatment cascade of people living with HIV (PLWH) in Iran and the reasons for gaps in HIV services in 2014. We did the cascade analysis using the WHO HIV test-treat-retain cascade analysis tool (2014). To measure the gaps, we check the records for all PLWH reported to the national HIV surveillance till September 2014 to define how many were alive, linked to HIV care, assessed for CD4 count, started antiretroviral therapy (ART), and reported to be alive up to five years after ART. To assess the reasons for gaps in the cascade, we ran desk review, four focus group discussions (FGD) and fifty one in-depth interviews with key informants including PLWH. Spectrum model estimated 75,700 PLWH in Iran, of whom, only 22,647 people (%30) were diagnosed. Of those who were diagnosed with HIV, 16,266 people (%72) enrolled in HIV care. About 13% of all PLWH retained in HIV care and only 9% (6,745 people) had ever tested for CD4 count. Only 8% (6,018 people) of all PLWH received ART by September 2014. We found the biggest gap in the HIV treatment cascade to be HIV diagnosis as only 30% of PLWH have been diagnosed. Innovative strategies to improve HIV testing, particularly those work best for key populations, is critical to reach the 90–90-90 targets.

Cascade Monitoring in Multidisciplinary Adolescent HIV Care Settings: Protocol for Utilizing Electronic Health Records

BACKGROUND

Past research shows that youth living with HIV (YLH) are not as engaged in the HIV treatment cascade as other HIV-positive populations. To achieve the health benefits of rapid and widespread testing and advanced pharmacologic treatment, YLH must be fully engaged in every stage of the treatment cascade. Cascade monitoring provides an opportunity to assess the youth care cascade, including engagement in care and when youth commonly drop out of care, across 10 clinical sites in the United States. Collecting electronic health record (EHR) data for prevention and care across participant recruitment venues within the Adolescent Medicine Trials Network (ATN) allows for monitoring of the prevention and care cascades within the ATN, for comparing the ATN population to large-scale surveillance, for future integration of technology-based interventions into EHRs, and for informing ATN strategic planning.

OBJECTIVE

The aim of this protocol study is to examine the trends in treatment cascade, including whether patients are receiving antiretroviral therapy, adhering to regimens, attending care appointments, and maintaining suppressed viral loads, to guide new protocol development and to facilitate community engagement. This protocol is part of the ATN Scale It Up (SIU) program described in this issue.

METHODS

Deidentified EHR data of YLH, aged 15 to 24 years, will be collected annually (2017 to 2022) from 10 ATN clinical sites, resulting in patient data from 2016 to 2021. These data will be transferred and stored using Dropbox Business, a Health Insurance Portability and Accountability Act-compliant site and then analyzed by the SIU analytic core.

RESULTS

This study was launched in December 2017 in 10 clinical sites, with 2016's EHR data due on January 31, 2017. All 10 sites electronically uploaded their EHR data. The mandatory variables requested to monitor cascade of care include date of visit, age, gender, height, weight, race, ethnicity, viral load, and International Classification of Diseases codes for other diagnosis. In total, 70% of the sites provided data for all mandatory variables. The remaining mandatory variables were manually extracted.

CONCLUSIONS

This study will provide a platform to determine how YLH across the nation progress through or drop out of the HIV treatment cascade. It will also provide a foundation for assessing impact of SIU projects on treatment cascade outcomes.

HIV Treatment Cascade by Housing Status at Enrollment: Results from a Retention in Care Cohort

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.

Factors affecting linkage to HIV care and ART initiation following referral for ART by a mobile health clinic in South Africa: evidence from a multimethod study

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.

Reasons for Accepting and Declining Free HIV Testing and Counseling Among Young African American Women Living in Disadvantaged Southern Urban Communities

Advancing HIV prevention and treatment among at-risk Southern communities of color requires understanding why voluntary HIV testing is accepted or declined. Reasons for testing decisions were investigated among young African American women (n = 223, mean age = 20.4 years) recruited from disadvantaged areas in a Southern US city. A free HIV test was offered following field interviews that assessed HIV risk behaviors and personal and social network characteristics; 69.1% accepted testing, and all were seronegative. After their decision, participants rated reasons for their choice, which were factor analyzed. A four-factor solution showed that test acceptance was related to (1) current sexual relationships and HIV risk concerns, (2) knowledge of HIV medical treatment benefits, (3) awareness of persons living with HIV, and (4) health protection and HIV test convenience. A three-factor solution showed that test refusal was related to (1) negative consequences of a positive test and privacy concerns, (2) low perception of HIV risk, and (3) anticipated social rejection if the test was positive. Comparisons of factor-based average item scores showed that health protection/HIV test convenience was rated as most influential in test acceptance decisions, whereas low perception of HIV risks was rated as most influential in test rejection decisions. The findings suggest that test acceptance can be promoted by offering free, convenient HIV testing as a health check in a testing context that assesses and provides feedback about participants' HIV risk levels.

Burden of HIV among young transgender women: factors associated with HIV infection and HIV treatment engagement

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.

The Facility-Level HIV Treatment Cascade: Using a Population Health Tool in Health Care Facilities to End the Epidemic in New York State

Background

The HIV treatment cascade is a tool for characterizing population-level gaps in HIV care, yet most adaptations of the cascade rely on surveillance data that are ill-suited to drive quality improvement (QI) activities at the facility level. We describe the adaptation of the cascade in health care organizations and report its use by HIV medical providers in New York State (NYS).

Methods

As part of data submissions to the NYS Department of Health, sites that provide HIV medical care in NYS developed cascades using facility-generated data. Required elements included data addressing identification of people living with HIV (PLWH) receiving any service at the facility, linkage to HIV medical care, prescription of antiretroviral therapy (ART), and viral suppression (VS). Sites also submitted a methodology report summarizing how cascade data were collected and an improvement plan identifying care gaps.

Results

Two hundred twenty-two sites submitted cascades documenting the quality of care delivered to HIV patients presenting for HIV- or non-HIV-related services during 2016. Of 101 341 PLWH presenting for any medical care, 75 106 were reported as active in HIV programs, whereas 21 509 had no known care status. Sites reported mean ART prescription and VS rates of 94% and 80%, respectively, and 60 distinct QI interventions.

Conclusions

Submission of facility-level cascades provides data on care utilization among PLWH that cannot be assessed through traditional HIV surveillance efforts. Moreover, the facility-level cascade represents an effective tool for identifying care gaps, focusing data-driven improvement efforts, and engaging frontline health care providers to achieve epidemic control.

HIV serostatus disclosure in the treatment cascade: evidence from Northern Tanzania

HIV serostatus disclosure plays an important role in HIV transmission risk reduction and is positively associated with HIV medication adherence and treatment outcomes. However, to date, no study has quantified the role of disclosure across the HIV treatment cascade, particularly in Sub-Saharan Africa. We used data from a cohort of HIV-infected adults in Northern Tanzania to describe associations between disclosure and engagement and retention in the HIV treatment cascade. Between 2008 and 2009, the Coping with HIV/AIDS in Tanzania (CHAT) study enrolled 260 clients newly diagnosed with HIV and 492 HIV-infected patients in established HIV care in two large HIV care and treatment centers in Northern Tanzania. Participants aged 18 and older completed annual clinical assessments and twice-annual in-person interviews for 3.5 years. Using logistic regression models, we assessed sociodemographic correlates of HIV serostatus disclosure to at least one household member, and associations between this disclosure measure and linkage to care, evaluation for antiretroviral therapy (ART) eligibility, ART coverage, and rates of undetectable HIV RNA levels during the follow-up period. Married individuals and those diagnosed earlier were more likely to have disclosed their HIV infection to at least one household member. During follow-up, HIV serostatus disclosure was associated with higher rates of linkage to care, evaluation for ART eligibility, and ART coverage. No significant association was observed with rates of undetectable viral loads. Marginal effects estimates suggest that a 10 percentage-point lower probability of linkage to care for those who did not disclose their HIV serostatus (86% vs. 96%; p = 0.035) was compounded by an 18 percentage-point lower probability of ever receiving a CD4 count (62% vs. 80%; p = .039), and a 20 percentage-point lower probability of ever receiving ART (55% vs. 75%; p = .029). If causal, these findings suggest an important role for disclosure assistance efforts across the HIV treatment cascade.

A Conditional Economic Incentive Fails to Improve Linkage to Care and Antiretroviral Therapy Initiation Among HIV-Positive Adults in Cape Town, South Africa

Interventions to improve antiretroviral therapy (ART) access are urgently needed to maximize the multiple benefits from ART. This pilot study examined the effect of a conditional economic incentive on linkage to care and uptake of treatment following ART referral by a mobile health clinic. Between April 2015 and May 2016, 86 individuals (≥18 years old) referred for ART in a resource-limited setting were randomized (1:1) to a control group or to an incentive: R300 cash (∼$23, or 3.5 days minimum wage in the domestic worker sector), conditional upon starting ART within 3 months. Outcome data were obtained from clinic records. The incentive effects on linkage to care (first clinic visit within 3 months) and ART initiation (treatment uptake within 3 months) were assessed using logistic regression. Overall, 67% linked to care and 42% initiated ART within 3 months after referral. No significant differences were found between the incentive and non-incentive group in terms of linkage to care [adjusted odds ratio (aOR): 0.70, 95% confidence interval (CI): 0.26-1.91] and initiation of ART (aOR: 0.67, 95% CI: 0.26-1.78). Ordinary least-squares regression analysis showed that incentivized individuals linked to care in fewer days (-7.9, 95% CI: -18.09 to 2.26) and started treatment in fewer days (-7.3, 95% CI: -27.01 to 12.38), but neither result was statistically significant. Our findings demonstrate poor treatment uptake by both the intervention and control participants and further highlight the challenge in achieving universal early treatment access. Further research is required to understand how economic incentives, which have been shown to have many benefits, can be applied to improve linkage to HIV care and treatment.

HIV Testing and awareness of HIV status among people who inject drugs in greater Kuala Lumpur, Malaysia

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.

Assessing the Feasibility of Smartphone Apps for HIV-Care Research with MSM and Transgender Individuals in Mpumalanga, South Africa

There is an urgent need to develop the HIV treatment cascade for men who have sex with men (MSM) and transgender individuals in rural Mpumalanga, South Africa. Mhealth tools such as smartphone applications have the potential to support HIV self-care behaviors. We conducted an exploratory study with HIV-positive community leaders to understand their current uses of cell phones and smartphones and to assess their interest in an HIV research study that utilized a smartphone application for HIV care support. A total of 18 community leaders were recruited to complete a questionnaire and focus group. We found that a large proportion of participants had smartphone access and were interested in a research study that utilized a smartphone application with secure access measures. We conclude that smartphone applications for HIV care research are feasible based on access and interest by MSM and transgender individuals in this rural setting.

The HIV treatment cascade and care continuum: updates, goals, and recommendations for the future

The HIV care continuum is a framework that models the dynamic stages of HIV care. The continuum consists of five main steps, which, at the population level, are depicted cross-sectionally as the HIV treatment cascade. These steps include diagnosis, linkage to care (LTC), retention in care (RiC), adherence to antiretroviral therapy (ART), and viral suppression. Although the HIV treatment cascade is represented as a linear, unidirectional framework, persons living with HIV (PLWH) often experience the care continuum in a less streamlined fashion, skip steps altogether, or even exit the continuum for a period of time and regress to an earlier stage. The proportion of PLWH decreases at each successive step of the cascade, beginning with an estimated 86% who are diagnosed and dropping dramatically to approximately 30% of PLWH who are virally suppressed in the United States (US). In this current issues review, we describe each step in the cascade, discuss targeted interventions that address weak points in the continuum, review domestic and international policies that help shape and direct HIV care strategies, and conclude with recommendations and future directions for HIV providers and policymakers. While we primarily examine issues related to domestic HIV care in the US, we also discuss international applications of the continuum in order to provide broader context.

The HIV care cascade: a systematic review of data sources, methodology and comparability

INTRODUCTION

The cascade of HIV diagnosis, care and treatment (HIV care cascade) is increasingly used to direct and evaluate interventions to increase population antiretroviral therapy (ART) coverage, a key component of treatment as prevention. The ability to compare cascades over time, sub-population, jurisdiction or country is important. However, differences in data sources and methodology used to construct the HIV care cascade might limit its comparability and ultimately its utility. Our aim was to review systematically the different methods used to estimate and report the HIV care cascade and their comparability.

METHODS

A search of published and unpublished literature through March 2015 was conducted. Cascades that reported the continuum of care from diagnosis to virological suppression in a demographically definable population were included. Data sources and methods of measurement or estimation were extracted. We defined the most comparable cascade elements as those that directly measured diagnosis or care from a population-based data set.

RESULTS AND DISCUSSIONS

Thirteen reports were included after screening 1631 records. The undiagnosed HIV-infected population was reported in seven cascades, each of which used different data sets and methods and could not be considered to be comparable. All 13 used mandatory HIV diagnosis notification systems to measure the diagnosed population. Population-based data sets, derived from clinical data or mandatory reporting of CD4 cell counts and viral load tests from all individuals, were used in 6 of 12 cascades reporting linkage, 6 of 13 reporting retention, 3 of 11 reporting ART and 6 of 13 cascades reporting virological suppression. Cascades with access to population-based data sets were able to directly measure cascade elements and are therefore comparable over time, place and sub-population. Other data sources and methods are less comparable.

CONCLUSIONS

To ensure comparability, countries wishing to accurately measure the cascade should utilize complete population-based data sets from clinical data from elements of a centralized healthcare setting, where available, or mandatory CD4 cell count and viral load test result reporting. Additionally, virological suppression should be presented both as percentage of diagnosed and percentage of estimated total HIV-infected population, until methods to calculate the latter have been standardized.
