RESUMEN

BACKGROUND: In Malawi approximately, 88.3% people living with HIV are aware of their HIV status. Significant gaps are among men aged 15-34 years; only 72% know their HIV status. To reach men, Jhpiego, in collaboration with the Ministry of Health (MOH), implemented the Men's Mobile Wellness Clinic (MMWC) at workplace settings in Blantyre, Malawi between October 2019 and March 2020. METHODS: We conducted a descriptive qualitative study to understand motivators and barriers to MMWC service uptake by employees and employers. Primary data was drawn from in-depth telephone interviews from four study populations: employers who accepted or declined to host the MMWC at their worksite, and employees who accessed or did not access the services. We performed a thematic analysis using Nvivo 12 software to identify patterns and themes across the dataset. FINDINGS: Main reasons given for using the service among male employees were a desire to know their health status, availability of free health services at the workplace, and good quality services offered by MMWC staff, and support from their supervisor. Men who did not access services stated reasons such as work-clinic scheduling conflicts, lack of adequate promotion of the service, and miscommunication on the criteria about who should attend the MMWC. Employers who accepted to host the MMWC stated convenience and employee's rights to know their health status. Those who declined either stated that employees did not want the services or COVID-19 preventive measures by the MOH between October 2019 and March 2020 restricted participation. CONCLUSION: This study underscores the potential utility of MMWC services including HIV testing among men. The desire to know their health status, availability of free MMWC services at the workplace, good quality services offered by MMWC staff, and the endorsement of MMWC by supervisors were main motivators to access the MMWC services. Sensitizing supervisors and employees about the benefits of the MMWC services, strengthening demand creation, and clarifying eligibility are important to facilitate MMWC uptake among men in Malawi.

RESUMEN

INTRODUCTION: Hazardous alcohol use (HAU), defined as a pattern of alcohol consumption that increases the risk of harmful consequences for the user or others, is associated with an elevated risk of human immunodeficiency virus (HIV) infection and poor health outcomes. We describe the association between people living with HIV (PLHIV) who report HAU and key HIV indicators. Gaps in current literature in estimating HAU on HIV outcomes at the regional level of Eastern and Southern Africa still exist and our analysis aims to address this issue. METHODS: We used weighted pooled data (2015-2017) from the nationally representative Population-based HIV Impact Assessments among adults who provided written consent aged 18-59 years from Eswatini, Malawi, Namibia, Tanzania, Zambia and Zimbabwe. We estimated differences in the prevalence of HIV infection and The Joint United Nations Programme on HIV and AIDS (UNAIDS) 90-90-90 indicators between PLHIV by HAU status using log-binomial regression, stratified by sex. HAU was determined using the Alcohol Use Identification Test-Consumption. RESULTS: Among the 9755 women and 4444 men who tested HIV positive, 6.6% of women and 21.8% of men engaged in HAU. Women who reported HAU were more likely to be HIV positive (adjusted prevalence ratio [aPR] = 1.31, 95% CI: 1.18-1.46) compared to those who did not report HAU. For the UNAIDS 90-90-90 targets, women who engaged in HAU were more likely to be unaware of their HIV-positive status (aPR = 1.22, 95% CI: 1.01-1.47) and not on antiretroviral therapy (ART) (aPR = 1.73, 95% CI: 1.26-2.37). Men who engaged in HAU were more likely to be unaware of their HIV-positive status (aPR = 1.56, 95% CI 1.39-1.76) and not on ART (aPR = 1.72, 95% CI: 1.30-2.29). No difference in viral load suppression, defined as <1000 copies/ml of HIV RNA, was seen by sex. CONCLUSIONS: PLHIV who engage in HAU were more likely to have suboptimal outcomes along the HIV care continuum when compared to those who did not engage in HAU. Targeted interventions, such as alcohol screening for HAU in HIV testing and treatment settings and HIV prevention efforts in alcohol-based venues, may help countries reach HIV epidemic control by 2030.

RESUMEN

BACKGROUND: Persons living with HIV infection (PLHIV) who are diagnosed in community settings in sub-Saharan Africa are particularly vulnerable to barriers to care that prevent or delay many from obtaining antiretroviral therapy (ART). METHODS: We conducted a retrospective cohort study to assess if a package of peer-delivered linkage case management and treatment navigation services (CommLink) was more effective than peer-delivered counseling, referral, and telephone follow-up (standard linkage services, SLS) in initiating and retaining PLHIV on ART after diagnosis in community settings in Eswatini. HIV-test records of 773 CommLink and 769 SLS clients aged ≥ 15 years diagnosed between March 2016 and March 2018, matched by urban and rural settings of diagnosis, were selected for the study. CommLink counselors recorded resolved and unresolved barriers to care (e.g., perceived wellbeing, fear of partner response, stigmatization) during a median of 52 days (interquartile range: 35-69) of case management. RESULTS: Twice as many CommLink than SLS clients initiated ART by 90 days of diagnosis overall (88.4% vs. 37.9%, adjusted relative risk (aRR): 2.33, 95% confidence interval (CI): 1.97, 2.77) and during test and treat when all PLHIV were eligible for ART (96.2% vs. 37.1%, aRR: 2.59, 95% CI: 2.20, 3.04). By 18 months of diagnosis, 54% more CommLink than SLS clients were initiated and retained on ART (76.3% vs. 49.5%, aRR: 1.54, 95% CI: 1.33, 1.79). Peer counselors helped resolve 896 (65%) of 1372 identified barriers of CommLink clients. Compared with clients with ≥ 3 unresolved barriers to care, 42% (aRR: 1.42, 95% CI: 1.19, 1.68) more clients with 1-2 unresolved barriers, 44% (aRR: 1.44, 95% CI: 1.25, 1.66) more clients with all barriers resolved, and 54% (aRR: 1.54, 95% CI: 1.30, 1.81) more clients who had no identified barriers were initiated and retained on ART by 18 months of diagnosis. CONCLUSIONS: To improve early ART initiation and retention among PLHIV diagnosed in community settings, HIV prevention programs should consider providing a package of peer-delivered linkage case management and treatment navigation services. Clients with multiple unresolved barriers to care measured as part of that package should be triaged for differentiated linkage and retention services.

RESUMEN

The success of antiretroviral therapy (ART) requires continuous engagement in care and optimal levels of adherence to achieve sustained HIV viral suppression. We evaluated HIV-care cascade costs and outcomes of a community-based, mobile HIV-care, peer-delivered linkage case-management program (CommLink) implemented in Manzini region, Eswatini. Abstraction teams visited referral facilities during July 2019-April 2020 to locate, match, and abstract the clinical data of CommLink clients diagnosed between March 2016 and March 2018. An ingredients-based costing approach was used to assess economic costs associated with CommLink. The estimated total CommLink costs were $2 million. Personnel costs were the dominant component, followed by travel, commodities and supplies, and training. Costs per client tested positive were $499. Costs per client initiated on ART within 7, 30, and 90 days of diagnosis were $2114, $1634, and $1480, respectively. Costs per client initiated and retained on ART 6, 12, and 18 months after diagnosis were $2343, $2378, and $2462, respectively. CommLink outcomes and costs can help inform community-based HIV testing, linkage, and retention programs in other settings to strengthen effectiveness and improve efficiency.

RESUMEN

BACKGROUND: Identifying men living with HIV in sub-Saharan Africa (SSA) is critical to end the epidemic. We describe the underlying factors of unawareness among men aged 15-59 years who ever tested for HIV in 13 SSA countries. METHODS: Using pooled data from the nationally representative Population-based HIV Impact Assessments, we fit a log-binomial regression model to identify characteristics related to HIV positivity among HIV-positive unaware and HIV-negative men ever tested for HIV. RESULTS: A total of 114,776 men were interviewed and tested for HIV; 4.4% were HIV-positive. Of those, 33.7% were unaware of their HIV-positive status, (range: 20.2%-58.7%, in Rwanda and Cote d'Ivoire). Most unaware men reported they had ever received an HIV test (63.0%). Age, region, marital status, and education were significantly associated with HIV positivity. Men who had HIV-positive sexual partners (adjusted prevalence ratio [aPR]: 5.73; confidence interval [95% CI]: 4.13 to 7.95) or sexual partners with unknown HIV status (aPR: 2.32; 95% CI: 1.89 to 2.84) were more likely to be HIV-positive unaware, as were men who tested more than 12 months compared with HIV-negative men who tested within 12 months before the interview (aPR: 1.58; 95% CI: 1.31 to 1.91). Tuberculosis diagnosis and not being circumcised were also associated with HIV positivity. CONCLUSION: Targeting subgroups of men at risk for infection who once tested negative could improve yield of testing programs. Interventions include improving partner testing, frequency of testing, outreach and educational strategies, and availability of HIV testing where men are accessing routine health services.

RESUMEN

INTRODUCTION: The scale-up of Universal Test and Treat has resulted in reductions in HIV morbidity, mortality and incidence. However, healthcare system and personal challenges have impacted the levels of treatment coverage achieved. We implemented interventions to improve linkage to care, retention, viral load (VL) coverage and service delivery, and describe the HIV care cascade over the course of the Botswana Combination Prevention Project (BCPP) study. METHODS: BCPP was designed to evaluate the impact of prevention interventions on HIV incidence in 30 communities in Botswana. We followed a longitudinal cohort of newly identified and known HIV-positive persons not on antiretroviral therapy (ART) identified through community-based testing activities through BCPP and referred with appointments to local HIV clinics in 15 intervention communities. Those who did not keep the first or follow-up appointments were tracked and traced through phone and home contacts. Improvements to service delivery models in the intervention clinics were also implemented. RESULTS: A total of 3,657 newly identified or HIV-positive persons not on ART were identified and referred to their local HIV clinic; 90% (3,282/3,657) linked to care and of those, 93% (3,066/3,282) initiated treatment. Near the end of the study, 221 persons remained >90 days late for appointments or missing. Tracing efforts identified 54/3,066 (2%) persons who initiated treatment but died, and 106/3,066 (3%) persons were located and returned to treatment. At study end, 61/3,066 (2%) persons remained missing and were never reached. Overall, 2,951 (98%) persons living with HIV (PLHIV) who initiated treatment were still alive, retained in care and still receiving ART out of the 3,001 persons alive at the end of the study. Of those on ART, 2,854 (97%) had current VL results and 2,784 (98%) of those were virally suppressed at study end. CONCLUSIONS: This study achieved high rates of linkage, treatment initiation, retention and VL coverage and suppression in a cohort of newly identified and known PLHIV not on ART. Tracking and tracing interventions effectively identified those persons who needed more resource intensive follow-up. The interventions implemented to improve service delivery and data quality may have also contributed to high linkage and retention rates. Clinical trial number: NCT01965470.

RESUMEN

INTRODUCTION: Achieving widespread knowledge of HIV-positive status is a crucial step to reaching universal ART coverage, population level viral suppression, and ultimately epidemic control. We implemented a multi-modality HIV testing approach to identify 90% or greater of HIV-positive persons in the Botswana Combination Prevention Project (BCPP) intervention communities. METHODS: BCPP is a cluster-randomized trial designed to evaluate the impact of combination prevention interventions on HIV incidence in 30 communities in Botswana. Community case finding and HIV testing that included home and targeted mobile testing were implemented in the 15 intervention communities. We described processes for identifying HIV-positive persons, uptake of HIV testing by age, gender and venue, characteristics of persons newly diagnosed through BCPP, and coverage of knowledge of status reached at the end of study. RESULTS: Of the 61,655 eligible adults assessed in home or mobile settings, 13,328 HIV-positive individuals, or 93% of the estimated 14,270 positive people in the communities were identified through BCPP. Knowledge of status increased by 25% over the course of the study with the greatest increases seen among men (37%) as compared to women (19%) and among youth aged 16-24 (77%) as compared to older age groups (21%). Although more men were tested through mobile than through home-based testing, higher rates of newly diagnosed HIV-positive men were found through home than mobile testing. CONCLUSIONS: Even when HIV testing coverage is high, additional gains can be made using a multi-modality HIV testing strategy to reach different sub-populations who are being missed by non-targeted program activities. Men and youth can be reached and will engage in community testing when services are brought to places they access routinely.

RESUMEN

INTRODUCTION: Non-citizens often face barriers to HIV care and treatment. Quantifying knowledge of positive HIV status and antiretroviral therapy (ART) coverage among non-citizens in a high HIV-prevalence country like Botswana that is close to achieving UNAIDS "90-90-90" targets may expose important gaps in achieving universal HIV testing and treatment. METHODS: The Botswana Combination Prevention Project (BCPP) is a pair-matched cluster-randomized trial evaluating the impact of prevention interventions on HIV incidence in 30 rural or peri-urban communities. Community case finding and HIV testing were conducted in home and mobile venues in 15 intervention communities from October 2013-September 2017. In this secondary analysis, we compared HIV positivity, knowledge of positive HIV-status, and ART status among all citizens and non-citizens assessed at intake in the intervention communities. RESULTS: HIV status was assessed in 57,556 residents in the intervention communities; 4% (n = 2,463) were non-citizens. Five communities accounted for 81% of the total non-citizens assessed. A lower proportion of non-citizens were HIV-positive (15%; n = 369) compared to citizens (21%; n = 11,416) [p = 0.026]; however, a larger proportion of non-citizens did not know their HIV-positive status prior to BCPP testing (75%) as compared to citizens (15%) [p = 0.003]. Among residents with knowledge of their HIV-positive status before BCPP, 79% of the non-citizens (72/91) were on ART compared to 86% (8,267/9,652) of citizens (p = 0.137). CONCLUSIONS: Although non-citizens were less likely to know their HIV-positive status compared to citizens, there were no differences in treatment uptake among non-citizens and citizens who knew their status. Designing interventions for non-citizens that provide HIV testing and treatment services commensurate to that of citizens as well as targeting communities with the largest number of non-citizens may help close a meaningful gap in the HIV care cascade and ensure ethical treatment for all HIV-positive persons. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01965470 (Botswana Combination Prevention Project).

RESUMEN

INTRODUCTION: HIV misdiagnosis leads to severe individual and public health consequences. Retesting for verification of all HIV-positive cases prior to antiretroviral therapy initiation can reduce HIV misdiagnosis, yet this practice has not been not widely implemented. METHODS: We evaluated and compared the cost of retesting for verification of HIV seropositivity (retesting) to the cost of antiretroviral treatment (ART) for misdiagnosed cases in the absence of retesting (no retesting), from the perspective of the health care system. We estimated the number of misdiagnosed cases based on a review of misdiagnosis rates, and the number of positives persons needing ART initiation by 2020. We presented the total and per person costs of retesting as compared to no retesting, over a ten-year horizon, across 50 countries in Africa grouped by income level. We conducted univariate sensitivity analysis on all model input parameters, and threshold analysis to evaluate the parameter values where the total costs of retesting and the costs no retesting are equivalent. Cost data were adjusted to 2017 United States Dollars. RESULTS AND DISCUSSION: The estimated number of misdiagnoses, in the absence of retesting was 156,117, 52,720 and 29,884 for lower-income countries (LICs), lower-middle income countries (LMICs), and upper middle-income countries (UMICs), respectively, totaling 240,463 for Africa. Under the retesting scenario, costs per person initially diagnosed were: $40, $21, and $42, for LICs, LMICs, and UMICs, respectively. When retesting for verification is implemented, the savings in unnecessary ART were $125, $43, and $75 per person initially diagnosed, for LICs, LMICs, and UMICs, respectively. Over the ten-year horizon, the total costs under the retesting scenario, over all country income levels, was $475 million, and was $1.192 billion under the no retesting scenario, representing total estimated savings of $717 million in HIV treatment costs averted. CONCLUSIONS: Results show that to reduce HIV misdiagnosis, countries in Africa should implement the WHO's recommendation of retesting for verification prior to ART initiation, as part of a comprehensive quality assurance program for HIV testing services.

RESUMEN

In 2017, the Joint United Nations Programme on HIV/AIDS (UNAIDS) estimated that worldwide, 36.9 million persons were living with human immunodeficiency virus (HIV) infection, the virus infection that causes acquired immunodeficiency syndrome (AIDS). Among persons with HIV infection, approximately 75% were aware of their HIV status, leaving 9.4 million persons with undiagnosed infection (1). Index testing, also known as partner notification or contact tracing, is an effective case-finding strategy that targets the exposed contacts of HIV-positive persons for HIV testing services. This report summarizes data from HIV tests using index testing in 20 countries supported by CDC through the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) during October 1, 2016-March 31, 2018. During this 18-month period, 1,700,998 HIV tests with 99,201 (5.8%) positive results were reported using index testing. The positivity rate for index testing was 9.8% among persons aged ≥15 years and 1.5% among persons aged <15 years. During the reporting period, HIV positivity increased 64% among persons aged ≥15 years (from 7.6% to 12.5%) and 67% among persons aged <15 years (from 1.2% to 2.0%). Expanding index testing services could help increase the number of persons with HIV infection who know their status, are initiated onto antiretroviral treatment, and consequently reduce the number of persons who can transmit the virus.

RESUMEN

In Botswana, 85% of persons living with HIV are aware of their status. We performed an economic analysis of HIV testing activities implemented during intensive campaigns, in 11 communities, between April 2015 and March 2016, through the Botswana Combination Prevention Project. The total cost was $1,098,312, or $99,847 per community, with 60% attributable to home-based testing and 40% attributable to mobile testing. The cost per person tested was $44, and $671 per person testing positive (2017 USD). Labor costs comprised 64% of total costs. In areas of high HIV prevalence and treatment coverage, the cost of untargeted home-based testing may be inflated by the efforts required to assess the testing eligibility of clients who are HIV-positive and on ART. Home-based and mobile testing delivered though an intensive community-based campaign allowed the identification of HIV positive persons, who may not access health facilities, at a cost comparable to other studies.

RESUMEN

Many children living with HIV in resource-limited settings remain undiagnosed and at risk for HIV-related mortality and morbidity. This article describes 5 key strategies for strengthening HIV case finding and linkage to treatment for infants, children, and adolescents. These strategies result from lessons learned during the Accelerating Children's HIV/AIDS Treatment Initiative, a public-private partnership between the President's Emergency Plan for AIDS Relief (PEPFAR) and the Children's Investment Fund Foundation (CIFF). The 5 strategies include (1) implementing a targeted mix of HIV case finding approaches (eg, provider-initiated testing and counseling within health facilities, optimization of early infant diagnosis, index family testing, and integration of HIV testing within key population and orphan and vulnerable children programs); (2) addressing the unique needs of adolescents; (3) collecting and using data for program improvement; (4) fostering a supportive political and community environment; and (5) investing in health system-strengthening activities. Continued advocacy and global investments are required to eliminate AIDS-related deaths among children and adolescents.

RESUMEN

In 2008, HIV rapid testing (HIV RT) was only minimally used in the Caribbean region. Collaboration with countries and international partners since then has resulted in greater availability and use of HIV RT services. Surveys were conducted in 2012 and 2014 among 11 selected Caribbean countries to inform stakeholders of progress made since 2008 and to identify strategies to further improve access and uptake of high-quality HIV RT in community- and facility-based settings in support of the UNAIDS 90-90-90 targets. Key accomplishments during this period include (1) presence of in-country national HIV RT algorithms, (2) use of the dried tube specimen (DTS) as an external quality assessment (EQA) program, (3) use of standardized logbooks for data collection and monitoring, and (4) use of oral fluid for HIV RT, particularly for key population surveys. Although progress has been made since 2008 to increase access and improve the quality of HIV RT among countries in the Caribbean, some work remains to be done. This includes the development of new policies and implementation of existing ones, task shifting, quality and access to testing, testing strategies, and integration of HIV RT into HIV Testing Services.

RESUMEN

We examined trends in cross-sectional HIV prevalence (a surrogate for incidence) and past 12 month testing behavior among young men who have sex with men (MSM). The Young Men's Survey and the National HIV Behavioral Surveillance System conducted interviews and HIV testing among MSM recruited by venue-based sampling during 1994-2011. Using data from five cities, we determined whether interview year was associated with HIV prevalence and recent testing for MSM ages 18-22 and 23-29 years, after adjusting for city, race/ethnicity, and education. Multivariable analysis demonstrated an overall increase in prevalence among MSM ages 23-29 years, driven by an increase in Baltimore. There was no change in HIV prevalence among MSM ages 18-22 years overall, although prevalence increased in Baltimore. HIV testing increased significantly for both age groups. Gains in HIV testing are encouraging, but increasing prevalence among young MSM in Baltimore suggests increasing incidence and the need for additional efforts for this population.

RESUMEN

BACKGROUND: Hepatitis A outbreaks are well documented among men who have sex with men (MSM). This analysis examines characteristics associated with hepatitis A virus (HAV) infection among a large group of young adult MSM from five USA cities. METHODS: The Young Men's Survey was a cross-sectional prevalence study of HIV infection and related behavioural risk factors among MSM aged 15-29 years during 1994-2000. Serum specimens from HIV-negative participants were retrospectively tested for antibodies to HAV (anti-HAV). Data were stratified by ethnicity and analysed with logistic regression. RESULTS: Overall anti-HAV prevalence was 18.4% among the 2708 participants, and varied by ethnicity from 6.9 to 45.3% and was highest among Hispanic and Asian men (P < 0.001). Prevalence increased with age across all racial/ethnic groups. Among white men, anti-HAV positivity was associated with having 20 or more lifetime male sex partners for those aged 15-22 years (adjusted odds ratio (AOR)=2.1, 95% confidence interval (CI)=1.0-4.1) and ever having had unprotected anal sex for those aged 23-29 years (AOR=2.4, 95% CI=1.2-4.5). CONCLUSIONS: Factors associated with a history of HAV infection among MSM in non-outbreak settings are probably similar to those among non-MSM. MSM are still at risk for HAV infection as a result of outbreaks occurring in MSM communities. Additional studies of hepatitis A vaccination coverage are needed to determine if strategies to vaccinate MSM are adequate.

RESUMEN

BACKGROUND: Among men who have sex with men (MSM) in the United States, the influence of HIV/AIDS complacency and beliefs about the efficacy of highly active antiretroviral therapy (HAART) on HIV-infection risk is unknown. METHODS: We analyzed data from a 1998-2000 cross-sectional 6-city survey of 1575 MSM aged 23 to 29 years who had never tested for HIV or had last tested HIV-negative to assess these plausible influences overall and by race/ethnicity. FINDINGS: Measured as strong endorsement for reduced HIV/AIDS concern due to HAART, HIV/AIDS complacency was associated with reporting ≥10 male sex partners (odds ratio [OR], 2.94; 95% confidence interval [CI], 2.12-4.07), unprotected anal intercourse with an HIV-positive or HIV-unknown-status male partner (OR, 2.06; 95% CI, 1.51-2.81), and testing HIV-positive (adjusted OR [AOR], 2.35; 95% CI, 1.38-3.98). Strong endorsement of the belief that HAART mitigates HIV/AIDS severity was more prevalent among black (21.8%) and Hispanic (21.3%) than white (9.6%) MSM (P < 0.001), and was more strongly associated with testing HIV-positive among black (AOR, 4.65; 95% CI, 1.97-10.99) and Hispanic (AOR, 4.12; 95% CI, 1.58-10.70) than white (AOR, 1.62; 95% CI, 0.64-4.11) MSM. CONCLUSIONS: Young MSM who are complacent about HIV/AIDS because of HAART may be more likely to engage in risk behavior and acquire HIV. Programs that target HIV/AIDS complacency as a means to reduce HIV incidence among young MSM should consider that both the prevalence of strong HAART-efficacy beliefs and the effects of these beliefs on HIV-infection risk might differ considerably by race/ethnicity.

RESUMEN

Despite considerable research, the causal relationship remains unclear between HIV/AIDS complacency, measured as reduced HIV/AIDS concern because of highly active antiretroviral therapy (HAART), and HIV risk behavior. Understanding the directionality and underpinnings of this relationship is critical for programs that target HIV/AIDS complacency as a means to reduce HIV incidence among men who have sex with men (MSM). This report uses structural equation modeling to evaluate a theory-based, HIV/AIDS complacency model on 1,593 MSM who participated in a venue-based, cross-sectional survey in six U.S. cities, 1998-2000. Demonstrating adequate fit and stability across geographic samples, the model explained 15.0% of the variance in HIV-acquisition behavior among young MSM. Analyses that evaluated alternative models and models stratified by perceived risk for HIV infection suggest that HIV/AIDS complacency increases acquisition behavior by mediating the effects of two underlying HAART-efficacy beliefs. New research is needed to assess model effects on current acquisition risk behavior, and thus help inform prevention programs designed to reduce HIV/AIDS complacency and HIV incidence among young MSM.
