“…One was a Zambia‐based quasi‐experimental study where patients receiving integrated ART and Tuberculosis (TB) care were more likely to link to care compared to controls [69]. The other was a US‐based simulation study that showed improved direct referral to linkage to care among adolescents and young adults using expanded testing sites [70].…”

IntroductionFollowing HIV testing services (HTS), the World Health Organization recommends prompt linkage to prevention and treatment. Scale‐up of effective linkage strategies is essential to achieving the global 95‐95‐95 goals for maintaining low HIV incidence by 2030 and reducing HIV‐related morbidity and mortality. Whereas linkage to care including same‐day antiretroviral therapy (ART) initiation for all people with HIV is now routinely implemented in testing programmes, linkage to HIV prevention interventions including behavioural or biomedical strategies, for HIV‐negative individuals remains sub‐optimal. This review aims to evaluate effective post‐HTS linkage strategies for HIV overall, and highlight gaps specifically in linkage to prevention.MethodsUsing the five‐step Arksey and O'Malley framework, we conducted a scoping review searching existing published and grey literature. We searched PubMed, Cochrane Library, CINAHL, Web of Science and EMBASE databases for English‐language studies published between 1 January 2010 and 30 November 2023. Linkage interventions included as streamlined interventions—involving same‐day HIV testing, ART initiation and point‐of‐care CD4 cell count/viral load, case management—involving linkage coordinators developing personalized HIV care and risk reduction plans, incentives—financial and non‐financial, partner services—including contact tracing, virtual—like social media, quality improvement—like use of score cards, and peer‐based interventions. Outcomes of interest were linkage to any form of HIV prevention and/or care including ART initiation.ResultsOf 2358 articles screened, 66 research studies met the inclusion criteria. Only nine linkage to prevention studies were identified (n = 9/66, 14%)—involving pre‐exposure prophylaxis, voluntary medical male circumcision, sexually transmitted infection and cervical cancer screening. Linkage to care studies (n = 57/66, 86%) focused on streamlined interventions in the general population and on case management among key populations.DiscussionDespite a wide range of HIV prevention interventions available, there was a dearth of literature on HIV prevention programmes and on the use of messaging on treatment as prevention strategy. Linkage to care studies were comparatively numerous except those evaluating virtual interventions, incentives and quality improvement.ConclusionsThe findings give insights into linkage strategies but more understanding of how to provide these effectively for maximum prevention impact is needed.

“…Generally, studies examined STI prevention and control in the population at large; exceptions to this were studies concerned with people living with HIV (n = 22) [5,9,[34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53], people who inject drugs (n = 5) [54][55][56][57][58], women (n = 16) [5,11,[59][60][61][62][63][64][65][66][67][68][69][70][71][72], children and young people (n = 11) [43,49,57,[72][73][74][75]…”

“…Of the HIV-focused studies, 33 were concerned with treatment [5,35-38,40,43-53, 56-60,67,69-71,74,84,87,91-93,98]. Of these, 17 examined aspects of the treatment cascade (e.g., commencement and/or adherence) [5,35,37,[43][44][45][48][49][50][51][52][53]57,67,69,74,87], 12 investigated the concept of treatment as prevention including in the context of vertical transmission [36,38,52,56-60,70,71,84,91,98], four focused on factors contributing to HIV drug resistance [40,46,92,93], and one concerned the provision of care to terminally ill patients [47].…”

“…Twenty-one studies had an HIV testing focus [5,37,42,43,[49][50][51]56,64,65,[69][70][71]74,85,87,[94][95][96][97][98], of which one was focused on home-or self-testing [85]. Twenty-five studies focused on issues related to HIV harm reduction, including intentional transmission [9], stigma [41], sexual behaviours and 'high risk' behaviours [38,39,58,59,61,[76][77][78][79]89,90], female condom use [11], PrEP [39,42,62,[81][82][83]98], injecting drug use [54,56,58], and general preventative measures [63,66].…”

“…Most studies were focused on high-level or abstract systems-namely, society-at-large or the health system in general terms. Seventeen studies applied systems thinking to specific health settings such as hospitals and health clinics [10,11,43,[47][48][49][50]52,62,64,65,[68][69][70][71]74,95]. Other settings included specific non-government organizations and community groups [42,52,75,78,86], prisons [59], schools [73,77], policy communities [45,51], sex on premises venues [11], and supervised drug injecting facilities [54].…”

Systems thinking is a mechanism for making sense of complex systems that challenge linear explanations of cause-and-effect. While the prevention and control of sexually transmissible infections (STIs) has been identified as an area that may benefit from systems-level analyses, no review on the subject currently exists. The aim of this study is to conduct a scoping review to identify literature in which systems thinking has been applied to the prevention and control of STIs among adolescent and adult populations. Joanna Briggs Institute guidelines for the conduct of scoping reviews were followed. Five databases were searched for English-language studies published after 2011. A total of n = 6102 studies were screened against inclusion criteria and n = 70 were included in the review. The majority of studies (n = 34) were conducted in African nations. Few studies focused on priority sub-populations, and 93% were focused on HIV (n = 65). The most commonly applied systems thinking method was system dynamics modelling (n = 28). The review highlights areas for future research, including the need for more STI systems thinking studies focused on: (1) migrant and Indigenous populations; (2) conditions such as syphilis; and (3) innovations such as pre-exposure prophylaxis and at-home testing for HIV. The need for conceptual clarity around ‘systems thinking’ is also highlighted.
