Abstract
Objective World Health Organization recommends promoting breastfeeding without restricting its duration among HIV-positive women on lifelong antiretroviral treatment (ART). There is little data on breastfeeding duration and mother to child transmission (MTCT) beyond 24 months. We compared the duration of breastfeeding in HIV-exposed and HIV-unexposed children and we identified factors associated with postpartum-MTCT in a semi-rural population of Mozambique. Methods This cross-sectional assessment was conducted from October-2017 to April-2018. Mothers who had given birth within the previous 48-months in the Manhiça district were randomly selected to be surveyed and to receive an HIV-test along with their children. Postpartum MTCT was defined as children with an initial HIV positive result beyond 6 weeks of life who initiated breastfeeding if they had a first negative PCR result during the first 6 weeks of life or whose mother had an estimated date of infection after the child’s birth. Cumulative incidence accounting for right-censoring was used to compare breastfeeding duration in HIV-exposed and unexposed children. Fine-Gray regression was used to assess factors associated with postpartum-MTCT. Results Among the 5000 mother-child pairs selected, 69.7% (3486/5000) were located and enrolled. Among those, 27.7% (967/3486) children were HIV-exposed, 62.2% (2169/3486) were HIV-unexposed and for 10.0% (350/3486) HIV-exposure was unknown. Median duration of breastfeeding was 13.0 (95%CI:12.0–14.0) and 20.0 (95%CI:19.0–20.0) months among HIV-exposed and HIV-unexposed children, respectively (p<0.001). Of the 967 HIV-exposed children, 5.3% (51/967) were HIV-positive at the time of the survey. We estimated that 27.5% (14/51) of the MTCT occurred during pregnancy and delivery, 49.0% (2551) postpartum-MTCT and the period of MTCT remained unknown for 23.5% (12/51) of children. In multivariable analysis, mothers’ ART initiation after the date of childbirth was associated (aSHR:9.39 [95%CI:1.75–50.31], p = 0.001), however breastfeeding duration was not associated with postpartum-MTCT (aSHR:0.99 [95%CI:0.96–1.03], p = 0.707). Conclusion The risk for postpartum MTCT was nearly tenfold higher in women newly diagnosed and/or initiating ART postpartum. This highlights the importance of sustained HIV screening and prompt ART initiation in postpartum women in Sub-Saharan African countries. Under conditions where HIV-exposed infants born to mothers on ART receive adequate PMTCT, extending breastfeeding duration may be recommended.

Abstract
OBJECTIVES Person-centred care (PCC) meets the needs of individuals by increasing convenience, providing supportive and culturally appropriate services to diverse populations, and engaging families, communities, and stakeholders in planning and provision of care. While the evidence demonstrates that PCC approaches can lead to clinical improvements across the HIV care continuum, it is not yet well defined in the context of HIV service delivery. METHODS A systematic review was conducted to define PCC practices for HIV treatment services in health facilities in sub-Saharan Africa. Data synthesis led to the development of a PCC framework including domain and sub-domain development. The study team used the Effective Public Health Project Practice tool for quantitative studies to assess the quality of the included studies. RESULTS Thirty-one studies from 12 countries met the inclusion criteria, including 56,586 study participants (females 42%-100% and males 0%-58%), resulting in three major domains and 11 sub-domains. These include staffing (sub-domains of composition, availability, and competency); service delivery standards (sub-domains of client feedback mechanisms; service efficiency and integration; convenience and access; and digital health worker support tools); and direct client support services (sub-domains of psychosocial services, logistics support, client-agency, and digital client support tools). Twenty-five of the person-centred interventions within these domains resulted in improvements in linkage to care, treatment retention, and/or viral suppression. CONCLUSIONS The PCC framework can help to provide a more consistent classification of HIV treatment interventions and will support improved assessment of these interventions to ensure that people receive personalised care.

Improving retention in antenatal and postnatal care: a systematic review of evidence to inform strategies for adolescents and young women living with HIV. J Int AIDS Soc 2021; 24:e25770. [PMID: 34449121 PMCID: PMC8395389 DOI: 10.1002/jia2.25770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 05/17/2021] [Accepted: 06/01/2021] [Indexed: 11/10/2022] Open
Abstract
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 abstraction 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.

Community-based adherence clubs for postpartum women on antiretroviral therapy (ART) in Cape Town, South Africa: a pilot study. BMC Health Serv Res 2020; 20:621. [PMID: 32641032 PMCID: PMC7341610 DOI: 10.1186/s12913-020-05470-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Accepted: 06/25/2020] [Indexed: 12/05/2022] Open
Abstract
BACKGROUND With an increasing number of countries implementing Option B+ guidelines of lifelong antiretroviral therapy (ART) for all pregnant and breastfeeding women, there is urgent need to identify effective approaches for retaining this growing and highly vulnerable population in ART care. METHODS Newly postpartum, breastfeeding women who initiated ART in pregnancy and met eligibility criteria were enrolled, and offered the choice of two options for postpartum ART care: (i) referral to existing network of community-based adherence clubs or (ii) referral to local primary health care clinic (PHC). Women were followed at study measurement visits conducted separately from either service. Primary outcome was a composite endpoint of retention in ART services and viral suppression [VS < 50 copies/mL based on viral load (VL) testing at measurement visits] at 12 months postpartum. Outcomes were compared across postpartum services using chi-square, Fisher's exact tests and Poisson regression models. The primary outcome was compared across services where women were receiving care at 12 months postpartum in exploratory analyses. RESULTS Between February and September 2015, 129 women (median age: 28.9 years; median time postpartum: 10 days) were enrolled with 65% opting to receive postpartum HIV care through an adherence club. Among 110 women retained at study measurement visits, 91 (83%) achieved the composite endpoint, with no difference between those who originally chose clubs versus those who chose PHC services. Movement from an adherence club to PHC services was common: 31% of women who originally chose clubs and were engaged in care at 12 months postpartum were attending a PHC service. Further, levels of VS differed significantly by where women were accessing ART care at 12 months postpartum, regardless of initial choice: 98% of women receiving care in an adherence club and 76% receiving care at PHC had VS < 50 copies/mL at 12 months postpartum (p = 0.001). CONCLUSION This study found comparable outcomes related to retention and VS at 12 months postpartum between women choosing adherence clubs and those choosing PHC. However, movement between postpartum services among those who originally chose adherence clubs was common, with poorer VS outcomes among women leaving clubs and returning to PHC services. TRIAL REGISTRATION ClinicalTrials.gov NCT02417675 , April 16, 2015 (retrospectively registered).

Abstract
BACKGROUND Improving maternal antiretroviral therapy (ART) retention and adherence is a critical challenge facing prevention of mother-to-child transmission (PMTCT) of HIV programs. There is an urgent need for evidence-based, cost-effective, and scalable interventions to improve maternal adherence and retention that can be feasibly implemented in overburdened health systems. Brief video-based interventions are a promising but underutilized approach to this crisis. We describe a trial protocol to evaluate the effectiveness and implementation of a standardized educational video-based intervention targeting HIV-infected pregnant women that seeks to optimize their ART retention and adherence by providing a VITAL Start (Video intervention to Inspire Treatment Adherence for Life) before committing to lifelong ART. METHODS This study is a multisite parallel group, randomized controlled trial assessing the effectiveness of a brief facility-based video intervention to optimize retention and adherence to ART among pregnant women living with HIV in Malawi. A total of 892 pregnant women living with HIV and not yet on ART will be randomized to standard-of-care pre-ART counseling or VITAL Start. The primary outcome is a composite of retention and adherence (viral load < 1000 copies/ml) 12 months after starting ART. Secondary outcomes include assessments of behavioral adherence (self-reported adherence, pharmacy refill, and tenofovir diphosphate concentration), psychosocial impact, and resource utilization. We will also examine the implementation of VITAL Start via surveys and qualitative interviews with patients, partners, and health care workers and conduct cost-effectiveness analyses. DISCUSSION This is a robust evaluation of an innovative facility-based video intervention for pregnant women living with HIV, with the potential to improve maternal and infant outcomes.

Abstract
OBJECTIVE To evaluate the effectiveness of the prevention of mother-to-child transmission (PMTCT) Option B+ programme in two provinces with high human immunodeficiency virus (HIV) burden in Mozambique over the first four years of programme implementation. METHODS We assessed the PMTCT cascade in antenatal care (ANC) from July 2013 to December 2017 using facility-level data and performed a retrospective cohort analysis with patient-level data. We compared the 12-month antiretroviral therapy (ART) retention rates between women with HIV infection who initiated ART under Option B+ ('B+ pregnant') and those who initiated ART for their own health ('own health'). RESULTS A total of 916 280 pregnant women enrolled in ANC. The proportion of women with a documented HIV status increased from 93% in 2013 to 96% in 2017. The proportion of those tested HIV-positive decreased from 8% to 6% while that of those HIV-positive on ART increased from 42% to 95%. Of the 44 377 HIV-positive women included in the analysis, 35% were lost to care. 'B+ pregnant' women initiating ART in 2015 were less likely to have no follow-up (NFU) compared with 'own health' women starting ART during the same period (adjusted odds ratio: 0.77, 95% confidence interval [CI]: 0.64-0.94, P = 0.01). There was no statistical difference between the two groups during the other years in which ART was initiated. Of those returning for care after their first visit (N = 39 801), the 'B+ pregnant' women showed a higher risk of non-retention than the other group (adjusted hazard ratio: 1.14, 95% CI: 1.03-1.25) when ART was initiated in 2013. The risk decreased during the subsequent years, with no difference observed between the groups. CONCLUSION PMTCT Option B+ programme scale-up has yielded positive results, including the maintenance of high HIV testing and ART initiation rates in ANC. Challenges still remain, however, in improving immediate engagement in care and long-term retention. Seeking alternative service delivery models to support existing health systems and prevent defaulters is required to achieve the UNAIDS 95-95-95 targets for PMTCT in Mozambique.

Impact of universal antiretroviral therapy for pregnant and postpartum women on antiretroviral therapy uptake and retention. AIDS 2019; 33:45-54.

Abstract
OBJECTIVE Universal eligibility for lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women ('Option B+') has been widely adopted, but concerns remain. We tested the hypothesis that the change from CD4+-guided ART eligibility ('Option A'), to Option B+, would improve maternal ART uptake and retention. DESIGN A stepped-wedge evaluation at 12 health facilities in eSwatini. METHODS Primary outcome was maternal retention: proportion of women attending clinic within 56 days of delivery (antenatal retention) and clinic attendance within 84 days of 6-months postpartum (postnatal retention). Generalized estimating equations examined impact of Option B+ vs. Option A. RESULTS Between 19 August 2013 and 29 August 2014, 2347 HIV-positive women, 55% (n = 1296) Option A, 45%, (n = 1051) Option B+ were included. ART initiation was observed in 36% (n = 469) of Option A women vs. 94% (n = 983) under Option B+ (P < 0.001). Overall 39% (n = 912) were retained from first ANC visit through 6-months postpartum. Retention was higher under Option B+ (53%, n = 559) vs. Option A (24%, n = 353) with variation by site and study month. Adjusting for age, gestational age, previous HIV diagnosis, and CD4+, Option B+ women were significantly more likely to be retained antenatally (aRR 1.32; 95% CI 1.18-1.49; P < 0.001) and postnatally (aRR 2.11; 95% CI 1.79-2.49) compared with Option A. Restricted to women initiating ART, retention was lower under Option B+ (57%, n = 558) vs. Option A (66%, n = 309; aRR, 0.82; 95% CI 0.70-0.95; P < 0.0001). CONCLUSION Compared with CD4+-guided ART eligibility, universal ART resulted in substantial increases in pregnant women initiating ART and retained in care through 6 months postpartum.

Background Implementation science in resource-poor countries and communities is arguably more important than implementation science in resource-rich settings, because resource poverty requires novel solutions to ensure that research results are translated into routine practice and benefit the largest possible number of people. Methods We reviewed the role of resources in the extant implementation science frameworks and literature. We analyzed opportunities for implementation science in resource-poor countries and communities, as well as threats to the realization of these opportunities. Results Many of the frameworks that provide theoretical guidance for implementation science view resources as contextual factors that are important to (i) predict the feasibility of implementation of research results in routine practice, (ii) explain implementation success and failure, (iii) adapt novel evidence-based practices to local constraints, and (iv) design the implementation process to account for local constraints. Implementation science for resource-poor settings shifts this view from “resources as context” to “resources as primary research object.” We find a growing body of implementation research aiming to discover and test novel approaches to generate resources for the delivery of evidence-based practice in routine care, including approaches to create higher-skilled health workers—through tele-education and telemedicine, freeing up higher-skilled health workers—through task-shifting and new technologies and models of care, and increasing laboratory capacity through new technologies and the availability of medicines through supply chain innovations. In contrast, only few studies have investigated approaches to change the behavior and utilization of healthcare resources in resource-poor settings. We identify three specific opportunities for implementation science in resource-poor settings. First, intervention and methods innovations thrive under constraints. Second, reverse innovation transferring novel approaches from resource-poor to research-rich settings will gain in importance. Third, policy makers in resource-poor countries tend to be open for close collaboration with scientists in implementation research projects aimed at informing national and local policy. Conclusions Implementation science in resource-poor countries and communities offers important opportunities for future discoveries and reverse innovation. To harness this potential, funders need to strongly support research projects in resource-poor settings, as well as the training of the next generation of implementation scientists working on new ways to create healthcare resources where they lack most and to ensure that those resources are utilized to deliver care that is based on the latest research results.

HIV treatment in pregnancy. Lancet HIV 2018; 5:e457-e467. [PMID: 29958853 DOI: 10.1016/s2352-3018(18)30059-6] [Citation(s) in RCA: 61] [Impact Index Per Article: 10.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2018] [Revised: 03/27/2018] [Accepted: 03/29/2018] [Indexed: 01/15/2023]
Abstract
Almost 25 years since antiretroviral therapy (ART) was first shown to prevent mother-to-child transmission of HIV, 76% of pregnant women living with HIV (over 1 million women) receive ART annually. This number is the result of successes in universal ART scale-up in low-income and middle-income countries. Despite unprecedented ART-related benefits to maternal and child health, challenges remain related to ART adherence, retention in care, and unequal access to ART. Implementation research is ongoing to understand and to address obstacles that lead to loss to follow-up. The biological mechanisms that underlie observed associations between antenatal ART and adverse outcomes in pregnancy and birth are not completely understood, with further research needed as well as strengthening of the systems to assess safety of antiretroviral drugs for the mother and HIV-exposed child. In the treat-all era, as duration of treatment and options for ART expand, pregnant women will remain a priority population for treatment optimisation to promote their health and that of their ART-exposed children.
