Introduction Findings from biomedical, behavioural and implementation studies provide a rich foundation to guide programmatic efforts for the prevention of mother‐to‐child HIV transmission (PMTCT). Methods We summarized the current evidence base to support policy makers, programme managers, funding agencies and other stakeholders in designing and optimizing PMTCT programmes. We searched the scientific literature for PMTCT interventions in the era of universal antiretroviral therapy for pregnant and breastfeeding women (i.e. 2013 onward). Where evidence was sparse, relevant studies from the general HIV treatment literature or from prior eras of PMTCT programme implementation were also considered. Studies were organized into six categories: HIV prevention services for women, timely access to HIV testing, timely access to ART, programme retention and adherence support, timely engagement in antenatal care and services for infants at highest risk of HIV acquisition. These were mapped to specific missed opportunities identified by the UNAIDS Spectrum model and embedded in UNICEF operational guidance to optimize PMTCT services. Results and discussion From May to November 2019, we identified numerous promising, evidence‐based strategies that, properly tailored and adopted, could contribute to population reductions in vertical HIV transmission. These spanned the HIV and maternal and child health literature, emphasizing the importance of continued alignment and integration of services. We observed overlap between several intervention domains, suggesting potential for synergies and increased downstream impact. Common themes included integration of facility‐based healthcare; decentralization of health services from facilities to communities; and engagement of partners, peers and lay workers for social support. Approaches to ensure early HIV diagnosis and treatment prior to pregnancy would strengthen care across the maternal lifespan and should be promoted in the context of PMTCT. Conclusions A wide range of effective strategies exist to improve PMTCT access, uptake and retention. Programmes should carefully consider, prioritize and plan those that are most appropriate for the local setting and best address existing gaps in PMTCT health services.

Introduction: To systematically review the literature on mother‐to‐child transmission in breastfed infants whose mothers received antiretroviral therapy and support the process of updating the World Health Organization infant feeding guidelines in the context of HIV and ART. Methods: We reviewed experimental and observational studies; exposure was maternal HIV antiretroviral therapy (and duration) and infant feeding modality; outcomes were overall and postnatal HIV transmission rates in the infant at 6, 9, 12 and 18 months. English literature from 2005 to 2015 was systematically searched in multiple electronic databases. Papers were analysed by narrative synthesis; data were pooled in random effects meta‐analyses. Postnatal transmission was assessed from four to six weeks of life. Study quality was assessed using a modified Newcastle‐Ottawa Scale (NOS) and GRADE. Results and discussion: Eleven studies were identified, from 1439 citations and review of 72 s. Heterogeneity in study methodology and pooled estimates was considerable. Overall pooled transmission rates at 6 months for breastfed infants with mothers on antiretroviral treatment (ART) was 3.54% (95% CI: 1.15–5.93%) and at 12 months 4.23% (95% CI: 2.97–5.49%). Postnatal transmission rates were 1.08 (95% CI: 0.32–1.85) at six and 2.93 (95% CI: 0.68–5.18) at 12 months. ART was mostly provided for PMTCT only and did not continue beyond six months postpartum. No study provided data on mixed feeding and transmission risk. Conclusions: There is evidence of substantially reduced postnatal HIV transmission risk under the cover of maternal ART. However, transmission risk increased once PMTCT ART stopped at six months, which supports the current World Health Organization recommendations of life‐long ART for all.

Introduction Recent international guidelines call for expanded access to triple‐drug antiretroviral therapy (ART) in HIV‐positive women during pregnancy and postpartum. However, high levels of non‐adherence and/or disengagement from care may attenuate the benefits of ART for HIV transmission and maternal health. We examined the frequency and predictors of disengagement from care among women initiating ART during pregnancy in Cape Town, South Africa. Methods We used routine medical records to follow‐up pregnant women initiating ART within prevention of mother‐to‐child transmission of HIV services in Cape Town, South Africa. Outcomes assessed through six months postpartum were (1) disengagement (no attendance within 56 days of a scheduled visit) and (2) missed visits (returning to care 14–56 days late for a scheduled visit). Results A total of 358 women (median age, 28 years; median gestational age, 26 weeks) initiated ART during pregnancy. By six months postpartum, 24% of women (n=86) had missed at least one visit and an additional 32% (n=115) had disengaged from care; together, 49% of women had either missed a visit or had disengaged by six months postpartum. Disengagement was more than twice as frequent postpartum compared to in the antenatal period (6.2 vs. 2.4 per 100 woman‐months, respectively; p<0.0001). In a proportional hazards model, later gestational age at initiation (HR: 1.04; 95% CI: 1.00–1.07; p=0.030) and being newly diagnosed with HIV (HR: 1.57; 95% CI: 1.07–2.33; p=0.022) were significant predictors of disengagement after adjusting for patient age, starting CD4 cell count and site of ART initiation. Conclusions These results demonstrate that missed visits and disengagement from care occur frequently, particularly post‐delivery, among HIV‐positive women initiating ART during pregnancy. Women who are newly diagnosed with HIV may be particularly vulnerable and there is an urgent need for interventions both to promote retention overall, as well as targeting women newly diagnosed with HIV during pregnancy.

Introduction Young pregnant and postpartum women living with HIV (WLHIV) are at high risk of poor outcomes in prevention of mother‐to‐child transmission services. The aim of this systematic review was to collate evidence on strategies to improve retention in antenatal and/or postpartum care in this population. We also conducted a secondary review of strategies to increase attendance at antenatal care (ANC) and/or facility delivery among pregnant adolescents, regardless of HIV status, to identify approaches that could be adapted for adolescents and young WLHIV. Methods Selected databases were searched on 1 December 2020, for studies published between January 2006 and November 2020, with screening and data ion by two independent reviewers. We identified papers that reported age‐disaggregated results for adolescents and young WLHIV aged <25 years at the full‐text review stage. For the secondary search, we included studies among female adolescents aged 10 to 19 years. Results and discussion Of 37 papers examining approaches to increase retention among pregnant and postpartum WLHIV, only two reported age‐disaggregated results: one showed that integrated care during the postpartum period increased retention in HIV care among women aged 18 to 24 years; and another showed that a lay counsellor‐led combination intervention did not reduce attrition among women aged 16 to 24 years; one further study noted that age did not modify the effectiveness of a combination intervention. Mobile health technologies, enhanced support, active follow‐up and tracing and integrated services were commonly examined as standalone interventions or as part of combination approaches, with mixed evidence for each strategy. Of 10 papers identified in the secondary search, adolescent‐focused services and continuity of care with the same provider appeared to be effective in improving attendance at ANC and/or facility delivery, while home visits and group ANC had mixed results. Conclusions This review highlights the lack of evidence regarding effective strategies to improve retention in antenatal and/or postpartum care among adolescents and young WLHIV specifically, as well as a distinct lack of age‐disaggregated results in studies examining retention interventions for pregnant WLHIV of all ages. Identifying and prioritizing approaches to improve retention of adolescents and young WLHIV are critical for improving maternal and child health.

Introduction HIV testing male partners of pregnant and postpartum women can lead to improved health outcomes for women, partners and infants. However, in sub‐Saharan Africa, few male partners get HIV tested during their partner's pregnancy in spite of several promising approaches to increase partner testing uptake. We assessed stakeholders’ views and preferences of partner notification, home‐based testing and secondary distribution of self‐test kits to understand whether offering choices for partner HIV testing may increase acceptability. Methods Interviewers conducted semi‐structured interviews with HIV‐negative (N = 39) and HIV‐positive (N = 41) pregnant/postpartum women, male partners of HIV‐negative (N = 14) and HIV‐positive (N = 14) pregnant/postpartum women, healthcare workers (N = 19) and policymakers (N = 16) in Malawi and Zambia. Interviews covered views of each partner testing approach and preferred approaches; healthcare workers were also asked about perceptions of a choice‐based approach. Interviews were transcribed, translated and analysed to compare perspectives across country and participant types. Results Most participants within each stakeholder group considered all three partner testing strategies acceptable. Relationship conflict was discussed as a potential adverse consequence for each approach. For partner notification, additional barriers included women losing letters, being fearful to give partners letters, being unable to read and men refusing to come to the clinic. For home‐based testing, additional barriers included lack of privacy or confidentiality and fear of experiencing community‐level HIV stigma. For HIV self‐test kits, additional barriers included lack of counselling, false results and poor linkage to care. Preferred male partner testing options varied. Participants preferred partner notification due to their respect for clinical authority, home‐based testing due to their desire to prioritize convenience and clinical authority, and self‐test kits due to their desire to prioritize confidentiality. Less than half of couples interviewed selected the same preferred male partner testing option as their partner. Most healthcare workers felt the choice‐based approach would be acceptable and feasible, but noted implementation challenges in personnel, resources or space. Conclusions Most stakeholders considered different approaches to partner HIV testing to be acceptable, but concerns were raised about each. A choice‐based approach may allow women to select their preferred method of partner testing; however, implementation challenges need to be addressed.

Introduction The implementation of lifelong antiretroviral treatment (ART) for all pregnant women (Option B+) in Malawi has resulted in a significant increase in the number of HIV‐positive pregnant women initiating treatment. However, research has highlighted the challenge of retaining newly initiated women in care. This study explores barriers and facilitators that affect a woman's decision to initiate and to adhere to Option B+. Methods A total of 39 in‐depth interviews and 16 focus group discussions were conducted. Eligible women were ≥18 years old, living with HIV and either pregnant and receiving antenatal care from a study site or had delivered a child within the last 18 months, breastfed their child and received services at one of the study sites. Eligible women were identified by healthcare workers (HCWs) in the antenatal clinic and ART unit. Focus groups were also conducted with HCWs employed in these departments. Qualitative data were analyzed using Maxqda version 10 (VERBI Software, Berlin, Germany). Results The general perception towards the drug regimen used in Option B+ was positive; women reported fewer side effects and acknowledged the positive benefits of ART. Women felt hopeful about prolonging their life and having an HIV‐uninfected baby, yet grappled with the fact that ART is a lifelong commitment. Women and HCWs discussed challenges with the counselling services for prevention of mother‐to‐child HIV transmission under the new Option B+ guidelines, and many women struggled with initiating ART on the same day as learning their HIV status. Women wanted to discuss their circumstances with their husbands first, receive a CD4 count and obtain an HIV test at another facility to confirm their HIV status. HCWs expressed concern that women might just agree to take the drugs to please them. HCWs also discussed concerns around loss to follow‐up and drug resistance. Conclusions Although Option B+ has significantly increased the number of women initiating ART, there are still challenges that need to be addressed to strengthen initiation, adherence and retention in care. Strategies to strengthen the counselling services upon diagnosis need to be developed to improve same‐day initiation of ART and long‐term adherence.

Introduction Women living with HIV are required to transition into the prevention of mother‐to‐child transmission of HIV (PMTCT) services when they become pregnant and back to ART services after delivery. Transition can be a vulnerable time when many women are lost from HIV care yet there is little guidance on the optimal transition approaches to ensure continuity of care. We reviewed the available evidence on existing approaches to transitioning women into and out of PMTCT, outcomes following transition and factors influencing successful transition. Methods We searched PubMed and SCOPUS, as well as s from international HIV‐focused meetings, from January 2006 to July 2020. Studies were included that examined three points of transition: pregnant women already on ART into PMTCT (transition 1), pregnant women living with HIV not yet on ART into treatment services (transition 2) and postpartum women from PMTCT into general ART services after delivery (transition 3). Results were grouped and reported as descriptions of transition approach, comparison of outcomes following transition and factors influencing successful transition. Results & discussion Out of 1809 s located, 36 studies (39 papers) were included in this review. Three studies included transition 1, 26 transition 2 and 17 transition 3. Approaches to transition were described in 26 studies and could be grouped into the provision of information at the point of transition (n = 8), strengthened communication or linkage of data between services (n = 4), use of transition navigators (n = 12), and combination approaches (n = 4). Few studies were designed to directly assess transition and only nine compared outcomes between transition approaches, with substantial heterogeneity in study design, setting and outcomes. Four themes were identified in 25 studies reporting on factors influencing successful transition: fear, knowledge and preparedness, clinic characteristics and the transition requirements and process. Conclusions This review highlights that, despite the need for women to transition into and out of PMTCT services for continued ART in many settings, there is very limited evidence on optimal transition approaches. Ongoing operational research is required to identify sustainable and acceptable transition approaches and service delivery models that support continuity of HIV care during and after pregnancy.

Introduction Prevention of mother‐to‐child transmission (PMTCT) has the potential to eliminate new HIV infections among infants. Yet in many parts of sub‐Saharan Africa, PMTCT coverage remains low, leading to unacceptably high rates of morbidity among mothers and new infections among infants. Intimate partner violence (IPV) may be a structural driver of poor PMTCT uptake, but has received little attention in the literature to date. Methods We conducted qualitative research in three Johannesburg antenatal clinics to understand the links between IPV and HIV‐related health of pregnant women. We held focus group discussions with pregnant women (n=13) alongside qualitative interviews with health care providers (n=10), district health managers (n=10) and pregnant abused women (n=5). Data were analysed in Nvivo10 using a team‐based approach to thematic coding. Findings We found qualitative evidence of strong bidirectional links between IPV and HIV among pregnant women. HIV diagnosis during pregnancy, and subsequent partner disclosure, were noted as a common trigger of IPV. Disclosure leads to violence because it causes relationship conflict, usually related to perceived infidelity and the notion that women are “bringing” the disease into the relationship. IPV worsened HIV‐related health through poor PMTCT adherence, since taking medication or accessing health services might unintentionally alert male partners of the women's HIV status. IPV also impacted on HIV‐related health via mental health, as women described feeling depressed and anxious due to the violence. IPV led to secondary HIV risk as women experienced forced sex, often with little power to negotiate condom use. Pregnant women described staying silent about condom negotiation in order to stay physically safe during pregnancy. Conclusions IPV is a crucial issue in the lives of pregnant women and has bidirectional links with HIV‐related health. IPV may worsen access to PMTCT and secondary prevention behaviours, thereby posing a risk of secondary transmission. IPV should be urgently addressed in antenatal care settings to improve uptake of PMTCT and ensure that goals of maternal and child health are met in sub‐Saharan African settings.

Introduction Community‐based mentor mothers (cMMs) are women living with HIV who provide peer support to pregnant/postpartum women living with HIV (PWLWH) to enhance antiretroviral therapy (ART) adherence, retention in care and prevent perinatal transmission of HIV. The goal of this study was to explore the experiences, perceptions, mechanisms and health impact of cMMs on PWLWH in Kenya from the perspective of cMMs. Methods We conducted a prospective mixed‐methods study in southwestern Kenya in 2015–2018. In the qualitative phase, we completed in‐depth interviews with cMMs to explore their perceptions and experiences in supporting PWLWH. Transcripts were broad‐coded according to identified themes, then fine‐coded using an inductive approach. In the quantitative phase, we analysed medical record data from PWLWH who were randomized in the cMM intervention to examine the impact of cMM visits on optimal prevention of mother‐to‐child transmission (PMTCT). We used cluster‐adjusted generalized estimating equation models to examine relationships with a composite outcome (facility delivery, infant HIV testing, ART adherence and undetectable viral load at 6 weeks postpartum). Finally, qualitative and quantitative results were integrated. Results Convergence of findings from cMM interviews (n = 24) and PWLWH medical data (n = 589) revealed: (1) The cMM intervention was utilized and perceived as acceptable. PWLWH received, on average, 6.2 of 8 intended home visits through 6 weeks postpartum. (2) The cMMs reported serving as role models and confidantes, supporting PWLWH's acceptance of their HIV status, providing assurances about PMTCT and assisting with male partner disclosure and communication. cMMs also described benefits for themselves, including empowerment and increased income. (3) The cMM visits supported PWLWH's completion of PMTCT steps. Having ≥4 cMM home visits up to 6 weeks postpartum, as compared to <4 visits, was associated with higher likelihood of an optimal PMTCT composite outcome (adjusted relative risk 1.42, p = 0.044). Conclusions We found that peer support from cMMs during pregnancy through 6 weeks postpartum was associated with improved uptake of critical PMTCT services and health behaviours and was perceived as beneficial for cMMs themselves. CMM support of PWLWH may be valuable for other low‐resource settings to improve engagement with lifelong ART and HIV services among PWLWH.

Aim To understand HIV stigma and self‐efficacy of labour and delivery (L&D) providers in caring for women living with HIV (WLHIV). Design Cross‐sectional descriptive mixed methods. Methods Data were collected in six primary healthcare facilities in the Kilimanjaro region, Tanzania between February and November 2022. We conducted eight focus groups with L&D providers (n = 36) and nurse‐midwifery students (n = 12). We conducted surveys with 60 L&D providers assessing HIV stigma (fear of acquisition, extra precautions and attitudes) and self‐efficacy in caring for WLHIV. Qualitative findings were complemented by survey data to provide a comprehensive understanding of providers' attitudes and experiences. Results Providers expressed fear of HIV acquisition when caring for WLHIV. Almost all providers noted that they used extra precautions with WLHIV; 97% used double gloves and 39% avoided touching WLHIV with bare hands, even when there were no bodily fluids. Most providers had positive attitudes towards WLHIV. Almost all rejected the idea that HIV was a punishment for bad behaviour, but 44% thought their patients might not be careful about infecting others. Qualitative data suggested providers worried that patients' reluctance to disclose their HIV status could raise the risk of occupational exposure. Provider self‐efficacy in normal birth was lower when caring for a woman with HIV compared with care for women who are HIV‐negative but did not differ significantly in other situations. Conclusion This study showed that providers had generally low‐stigmatising attitudes towards people living with HIV but feared occupational exposure, leading to avoidance of necessary patient contact. Training on clinical and interpersonal skills, coupled with evidence‐based care for women with HIV during childbirth, could benefit both providers and patients. Reporting Method The study is reported following the Good Reporting of a Mixed‐Methods Study (GRAMMS) checklist. Patient or Public Contribution Patients and the public were not involved in this research.
