"The targets…are driving the agenda and that probably needs to change": stakeholder perspectives on HIV partner notification in sub-Saharan Africa. BMC Public Health 2024; 24:521. [PMID: 38373972 PMCID: PMC10877856 DOI: 10.1186/s12889-023-17422-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 12/06/2023] [Indexed: 02/21/2024] Open
Abstract
BACKGROUND Voluntary assisted partner notification (VAPN) in HIV contact tracing is a globally recommended strategy to identify persons who have been exposed to HIV and link them to HIV testing and follow-up. However, there is little understanding about how VAPN is experienced by stakeholders in sub-Saharan African (SSA) contexts. We conducted a multi-level and multi-national qualitative analysis evaluating stakeholder perspectives surrounding VAPN implementation to inform the development of future VAPN policies. METHOD We conducted in-depth interviews (IDIs) with VAPN stakeholders at global (n = 5), national (n = 6), and community level (n = 4) across a total of seven SSA countries. Eligible participants were ≥ 18 years old and had experience developing, implementing, or overseeing VAPN policies in SSA. We sought to understand stakeholder's perspectives on policy development, implementation, and perceived outcomes (barriers and facilitators). Interviews were audio recorded, transcribed, and analyzed thematically using a combination of inductive and deductive approaches. RESULTS Between December 2019 and October 2020 we conducted 15 IDIs. While participants agreed that VAPN resulted in a high yield of people newly diagnosed with HIV; they noted numerous barriers surrounding VAPN implementation across global, national, and community levels, the majority of which were identified at community level. Barriers at global and national level included high target setting, contradictory laws, and limited independent research disenfranchising the experiences of implementing partners. The barriers identified at community level included client-level challenges (e.g., access to healthcare facilities and fear of adverse events); healthcare worker challenges (e.g., high workloads); limited data infrastructure; and cultural/gender norms that hindered women from engaging in HIV testing and VAPN services. In response to these barriers, participants shared implementation facilitators to sustain ethical implementation of VAPN services (e.g., contact tracing methods) and increase its yield (e.g., HIV self-testing integrated with VAPN services). CONCLUSION Overall, stakeholders perceived VAPN implementation to encounter barriers across all implementation levels (global to community). Future VAPN policies should be designed around the barriers and facilitators identified by SSA stakeholders to maximize the implementation of (ethical) HIV VAPN services and increase its impact in sub-Saharan African settings.

Abstract
OBJECTIVES The effectiveness of HIV index testing (IT) in Eastern Europe has not been described. This study reports the performance of a scaled IT programme in Ukraine. DESIGN This observational study included clients enrolled in IT services in 2020, and used routinely collected data from programme registers and the national electronic health record system. SETTING The study covered 39 public-sector health facilities where IT services were integrated into medical visits for persons living with HIV (PLHIV) already enrolled in HIV care. PARTICIPANTS Participants included PLHIV with both recent (<6 months) and previously established (≥6 months) HIV diagnoses. INTERVENTION Ukraine's physician-led IT model involves a cascade of steps including voluntary informed consent, partner elicitation, selection of partner notification method and follow-up with clients to ensure partners are notified, tested for HIV and linked to HIV prevention and treatment services, as needed. PRIMARY AND SECONDARY OUTCOME MEASURES Outcomes included contact index, testing, index and HIV case-finding index disaggregated by index client (IC) subgroups, including people with current or past injection drug use (PWID) and men who have sex with men (MSM). RESULTS Of 14 525 ICs offered index testing, 51.9% accepted, of whom 98.3% named at least one sexual, injection or biological child partner. In total, 14.9% of ICs were PWID and 3.5% were MSM. Clients named 8448 unique partners (contact index=1.14). HIV case finding averaged 0.14 cases per client, and was highest among clients with recent HIV diagnosis (0.29) and among PWID (0.23), and lower among clients with established HIV diagnosis (0.07). More than 90% of all partners with new HIV diagnoses were linked to care. CONCLUSIONS There was a high case-finding index among ICs with recent HIV and high linkage to care for all partners, demonstrating the effectiveness of this integrated, physician-led model implemented in 39 health facilities in Ukraine.

Implementation fidelity to HIV assisted partner services (aPS) during scale-up in western Kenya: a convergent mixed methods study. BMC Health Serv Res 2023; 23:511. [PMID: 37208724 DOI: 10.1186/s12913-023-09541-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 05/10/2023] [Indexed: 05/21/2023] Open
Abstract
BACKGROUND HIV assisted partner services (aPS) is an intervention to improve HIV status awareness among sex and drug-injecting partners of people newly diagnosed with HIV (index clients). Implementation fidelity-the degree to which an intervention is conducted as intended - is critical to effectiveness, but there are limited data about aPS fidelity when delivered by HIV testing service (HTS) providers. We explored factors affecting implementation fidelity to aPS in two high-HIV prevalence counties in western Kenya. METHODS We used convergent mixed methods adapting the conceptual framework for implementation fidelity within the aPS scale-up project. This was an implementation study examining scale-up of APS within HTS programs in Kisumu and Homa Bay counties that recruited male sex partners (MSPs) of female index clients. We defined implementation fidelity as the extent to which HTS providers followed the protocol for phone and in-person participant tracing at six expected tracing attempts. Quantitative data were collected from tracing reports in 31 facilities between November 2018 and December 2020, and in-depth interviews (IDIs) were conducted with HTS providers. Descriptive statistics were used to describe tracing attempts. IDIs were analyzed using thematic content analysis. RESULTS Overall, 3017 MSPs were mentioned of whom 98% (2969/3017) were traced, with most tracing attempts being successful (2831/2969, 95%). Fourteen HTS providers participated in the IDIs-mostly females (10/14, 71%) with a median age of 35 years (range 25-52), who all had post-secondary education (14/14, 100%). The proportion of tracing attempts occurring by phone ranged from 47 to 66%, with the highest proportion occurring on the first attempt and lowest on the sixth attempt. Contextual factors either enhanced or impeded implementation fidelity to aPS. Positive provider attitudes towards aPS and conducive work environment factors promoted implementation fidelity, while negative MSP responses and challenging tracing conditions impeded it. CONCLUSION Interactions at the individual (provider), interpersonal (client-provider), and health systems (facility) levels affected implementation fidelity to aPS. As policymakers prioritize strategies to reduce new HIV infections, our findings highlight the importance of conducting fidelity assessments to better anticipate and mitigate the impact of contextual factors during the scale-up of interventions.

Profile of partners who completed HIV testing and received a new HIV diagnosis in Ukraine's HIV index testing program: a retrospective cohort study to inform program improvement. BMC Infect Dis 2023; 23:291. [PMID: 37147618 PMCID: PMC10161989 DOI: 10.1186/s12879-023-08281-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Accepted: 04/26/2023] [Indexed: 05/07/2023] Open
Abstract
BACKGROUND Approximately one-third of people living with HIV in Ukraine are unaware of their HIV status. Index testing (IT) is an evidence-based HIV testing strategy that supports voluntary notification of partners with HIV risk, so they can receive HIV testing, prevention, and treatment services. METHODS Ukraine scaled up IT services in 2019. This observational study of Ukraine's IT program covered 39 health facilities located in 11 regions with high HIV burden. The study used routine program data from January-December 2020 to describe the profile of named partners and explore index client (IC) and partner factors associated with two outcomes: 1) completing testing; and 2) HIV case finding. Analysis used descriptive statistics and multilevel linear mixed regression models. RESULTS The study included 8,448 named partners, of whom 6,959 had unknown HIV status. Among them,72.2% completed HIV testing and 19.4% of those tested were newly diagnosed with HIV. Two-thirds of all new cases were among partners of ICs who were recently diagnosed and enrolled in care (< 6 months), while one third were among partners of established ICs. In adjusted analysis, partners of ICs with unsuppressed HIV viral load (VL) were less likely to complete HIV testing (adjusted odds ratio [aOR] = 0.11, p < 0.001), but more likely to receive a new HIV diagnosis (aOR = 1.92, p < 0.001). Partners of ICs who cited injection drug use or having a known HIV + partner as their own reason for testing were more likely to receive a new HIV diagnosis (aOR = 1.32, p = 0.04 and aOR = 1.71, p < 0.001 respectively). Involving providers in the partner notification process was associated with completed testing (aOR = 1.76, p = 0.001) and HIV case finding (aOR = 1.64, p < 0.01), compared with notification by ICs. CONCLUSION HIV case detection was highest among partners of recently diagnosed ICs, but IT participation among established ICs still yielded an important share of all newly-identified HIV cases. Areas for improvement in Ukraine's IT program include completing testing for partners of ICs with unsuppressed HIV VL, with history of injection drug use or discordant partnerships. Using intensified follow-up for the sub-groups at risk of incomplete testing may be practical. Greater use of provider-assisted notification could also accelerate HIV case finding.

Abstract
Background Despite progress toward the Joint United Nations Programme on HIV/AIDS “95-95-95” targets (95% of HIV-positive persons tested, 95% of tested persons on treatment, and 95% of treated persons virally suppressed), a gap remains in achieving the first 95% target. Assisted contact tracing (ACT), in which health workers support HIV-positive index clients to recruit their contacts (sexual partners and children) for HIV testing, efficiently identifies HIV-positive persons in need of treatment. Although many countries, including Malawi, began implementing ACT, testing outcomes in routine settings have been worse than those in trial settings. Objective The aim of this paper is to use formative research and frameworks to develop and digitize an implementation package to bridge the gap between ACT research and practice. Methods Semistructured qualitative research was conducted in 2019 in Malawi with key informants. Barriers and facilitators to intervention delivery were identified using the Consolidated Framework for Implementation Research. Approaches to digitization were examined using human-centered design principles. Results Limited clinic coordination and health worker capacity to address the complexities of ACT were identified as barriers. Ongoing individual training consisting of learning, observing, practicing, and receiving feedback, as well as group problem-solving were identified as facilitators. Important features of digitization included (1) culturally relevant visual content, (2) capability of offline use, and (3) simple designs and basic editing to keep costs low. Conclusions Formative research and frameworks played a key role in designing and digitizing an implementation package for ACT delivery in a low-income setting such as Malawi.

Abstract
BACKGROUND HIV index testing, an intervention in which HIV-positive "indexes" (persons diagnosed with HIV) are supported to recruit their "contacts" (sexual partners and children) efficiently identifies HIV-infected persons in need of treatment and HIV-uninfected persons in need of prevention. However, index testing implementation in sub-Saharan African health care settings has been suboptimal. The objective of this study was to develop and pilot test a blended learning capacity-building package to improve index testing implementation in Malawi. METHODS In 2019, a blended learning package combining digital and face-to-face training modalities was field tested at 6 health facilities in Mulanje, Malawi using a pre-/post- type II hybrid design with implementation and effectiveness outcomes. Health care worker (HCW) fidelity to the intervention was assessed via observed encounters before and after the training. Preliminary effectiveness was examined by comparing index testing program indicators in the 2 months before and 4 months after the training. Indicators included the mean number of indexes screened, contacts elicited, and contacts who received HIV testing per facility per month. RESULTS On a 30-point scale, HCW fidelity to index testing protocols improved from 6.0 pre- to 25.5 post-package implementation (P = 0.002). Index testing effectiveness indicators also increased: indexes screened (pre = 63, post = 101, P < 0.001); contacts elicited (pre = 75, post = 131, P < 0.001); and contacts who received HIV testing (pre = 27, post = 41, P = 0.014). CONCLUSIONS The blended learning package improved fidelity to index testing protocols and preliminary effectiveness outcomes. This package has the potential to enhance implementation of HIV index testing approaches, a necessary step for ending the HIV epidemic.

Abstract
HIV testing is a crucial first step to accessing HIV prevention and treatment services and to achieving the UNAIDS target of 95% of people living with HIV being aware of their status by 2030. Combined implementation of facility-based and community-based approaches has helped to achieve high levels of HIV testing coverage in many countries including those in sub-Saharan Africa. Approaches such as index testing and self-testing help to reach individuals at higher risk of acquiring HIV, men, and those less likely to use health facilities or community-based services. However, as the proportion of people living with HIV who are aware of their HIV status has risen, the challenge of reaching those who remain undiagnosed or those who are at high risk of acquiring HIV has grown. Demand generation and novel testing approaches will be necessary to reach undiagnosed people living with HIV and to promote frequent retesting among key and priority populations.

Abstract
INTRODUCTION HIV diagnosis is the necessary first step towards HIV care initiation, yet many persons living with HIV (PLWH) remain undiagnosed. Employing multiple HIV testing strategies in tandem could increase HIV detection and promote linkage to care. We aimed to assess an intervention to improve HIV detection within socio-sexual networks of PLWH in two sexually transmitted infections (STI) clinics in Lilongwe, Malawi. METHODS We conducted a randomized controlled trial to evaluate an intervention combining acute HIV infection (AHI) screening, contract partner notification and social contact referral versus the Malawian standard of care: serial rapid serological HIV tests and passive partner referral. Enrolment occurred between 2015 and 2019. HIV-seropositive persons (two positive rapid tests) were randomized to the trial arms and HIV-seronegative (one negative rapid test) and -serodiscordant (one positive test followed by a negative confirmatory test) persons were screened for AHI with HIV RNA testing. Those found to have AHI were offered enrolment into the intervention arm. Our primary outcome of interest was the number of new HIV diagnoses made per index participant within participants' sexual and social networks. We also calculated total persons, sexual partners and PLWH (including those previously diagnosed) referred per index participant. RESULTS A total of 1230 HIV-seropositive persons were randomized to the control arm, and 561 to the intervention arm. Another 12,713 HIV-seronegative or -serodiscordant persons underwent AHI screening, resulting in 136 AHI cases, of whom 94 enrolled into the intervention arm. The intervention increased the number of new HIV diagnoses made per index participant versus the control (ratio: 1.9; 95% confidence interval (CI): 1.2 to 3.1). The intervention also increased the numbers of persons (ratio: 2.5; 95% CI: 2.0 to 3.2), sexual partners (ratio: 1.7; 95% CI: 1.4 to 2.0) and PLWH (ratio: 2.3; 95% CI: 1.7 to 3.2) referred per index participant. CONCLUSIONS Combining three distinct HIV testing and referral strategies increased the detection of previously undiagnosed HIV infections within the socio-sexual networks of PLWH seeking STI care. Combination HIV detection strategies that leverage AHI screening and socio-sexual contact networks offer a novel and efficacious approach to increasing HIV status awareness.

Abstract
PURPOSE OF REVIEW Knowledge of HIV status is the gateway to HIV treatment and prevention, and optimizing this pillar is essential to bend the curve of the HIV epidemic toward zero new infections. This review will discuss the epidemiology of serostatus awareness, including disparities among key populations, and explore interventions and societal barriers. RECENT FINDINGS Rates of serostatus awareness have improved overall; however, progress is lagging in many regions, nations and populations, with substantial disparities seen among key populations. These populations and their partners now contribute the majority of new infections, fueling the epidemic. Data support a variety of interventions that have demonstrated effectiveness in increasing new diagnoses, particularly among underserved populations. Structural and societal barriers such as stigma, discriminatory laws and policies, and social determinants of health disproportionately affect key populations, and these must be addressed to achieve equity and end the epidemic. SUMMARY According to United Nations Programme on HIV/AIDS (UNAIDS), the pace of progress toward epidemic control has slowed. Achieving substantial increases in serostatus awareness to meet 2020 and 2030 UNAIDS goals will require attacking complex societal barriers while bringing evidence-based interventions to scale in each nation and key population. A robust advocacy effort is now needed as political will and funding wane.
