Vulnerable at Each Step in the PMTCT Care Cascade: High Loss to Follow Up During Pregnancy and the Postpartum Period in Tanzania.

ABSTRACT: In 2013, Tanzania adopted the World Health Organization's Option B+ guidelines for prevention of mother-to-child transmission of HIV (PMTCT), whereby all HIV-infected pregnant women initiate lifelong antiretroviral therapy. This study examined retention in PMTCT across critical junctures in the care continuum. This was a retrospective study of patient-level data for a cohort of women enrolled in PMTCT during the first year of Option B+ in Tanzania. Retention in care was described across three periods: (1) the first month of antenatal care (ANC), (2) pregnancy, and (3) the postpartum period. Logistic regression was used to identify factors associated with loss to follow up (LTFU) during the first month of ANC. Survival analyses were used to identify factors associated with LTFU during pregnancy and the postpartum periods. 650 participants were included in the cohort; 262 (40.3%) were newly diagnosed with HIV. Two years after delivery, 383/650 (58.7%) were LTFU. Of the 383 LTFU, 73 (19.1%) were lost during the first month of ANC, 44 (11.5%) during pregnancy, and 266 (69.5%) after delivery. Being newly diagnosed with HIV predicted higher LTFU during the first month of ANC (aOR 1.76; 95% CI 1.06-2.94) and faster time to LTFU during the postpartum period (adjusted relative time, 0.68; 95% CI 0.51-0.89). High LTFU occurred across the PMTCT continuum, including immediately after enrollment into ANC and the postpartum period. Ongoing research is needed to encourage treatment uptake and sustained engagement after delivery.

Project description:Prevention of mother-to-child transmission of HIV (PMTCT) is a foundational component of a comprehensive HIV treatment program. In addition to preventing vertical transmission to children, PMTCT is an important catch-point for universal test-and-treat strategies that can reduce community viral load and slow the epidemic. However, systematic reviews suggest that care engagement in PMTCT programs is sub-optimal. This study enrolled a cohort of 200 women initiating PMTCT in Kilimanjaro, Tanzania, and followed them to assess HIV care engagement and associated factors. Six months after delivery, 42/200 (21%) of participants were identified as having poor care engagement, defined as HIV RNA >200?copies/mL or, if viral load was unavailable, being lost-to-follow-up in the clinical records or self-reporting being out of care. In a multivariable risk factor analysis, younger women were more likely to have poor postpartum care engagement; with each year of age, women were 7% less likely to have poor care engagement (aRR: 0.93; 95% CI: 0.89, 0.98). Additionally, women who had told at least one person about their HIV status were 47% less likely to have poor care engagement (aRR: .53; 95% CI: 0.29, 0.97). Among women who entered antenatal care with an established HIV diagnosis, those who were pregnant for the first time had increased risk of poor care engagement (aRR 4.16; 95% CI 1.53, 11.28). The findings suggest that care engagement remains a concern in PMTCT programs, and must be addressed to realize the goals of PMTCT. Comprehensive counseling on HIV disclosure, along with community-based stigma reduction programs to provide a supportive environment for people living with HIV, are crucial to address barriers to care engagement and support long-term treatment. Women presenting to antenatal care with an established HIV status require support for care engagement during the crucial period surrounding childbirth, particularly those pregnant for the first time.

Project description:BackgroundSmoking during pregnancy (SDP) and the postpartum period has serious health outcomes for the mother and infant. Although some systematic reviews have shown the impact of maternal SDP on particular conditions, a systematic review examining the overall health outcomes has not been published. Hence, this paper aimed to conduct an umbrella review on this issue.MethodsA systematic review of systematic reviews (umbrella review) was conducted according to a protocol submitted to PROSPERO ( CRD42018086350 ). CINAHL, EMBASE, MEDLINE, PsycINFO, Web of Science, CRD Database and HMIC databases were searched to include all studies published in English by 31 December 2017, except those focusing exclusively on low-income countries. Two researchers conducted the study selection and quality assessment independently.ResultsThe review included 64 studies analysing the relationship between maternal SDP and 46 health conditions. The highest increase in risks was found for sudden infant death syndrome, asthma, stillbirth, low birth weight and obesity amongst infants. The impact of SDP was associated with the number of cigarettes consumed. According to the causal link analysis, five mother-related and ten infant-related conditions had a causal link with SDP. In addition, some studies reported protective impacts of SDP on pre-eclampsia, hyperemesis gravidarum and skin defects on infants. The review identified important gaps in the literature regarding the dose-response association, exposure window, postnatal smoking.ConclusionsThe review shows that maternal SDP is not only associated with short-term health conditions (e.g. preterm birth, oral clefts) but also some which can have life-long detrimental impacts (e.g. obesity, intellectual impairment).ImplicationsThis umbrella review provides a comprehensive analysis of the overall health impacts of SDP. The study findings indicate that while estimating health and cost outcomes of SDP, long-term health impacts should be considered as well as short-term effects since studies not including the long-term outcomes would underestimate the magnitude of the issue. Also, interventions for pregnant women who smoke should consider the impact of reducing smoking due to health benefits on mothers and infants, and not solely cessation.

Project description:IntroductionViolence against women is a public health problem that poses serious consequences for victims and their environments. The healthcare system struggles to assess this phenomenon during prenatal and postpartum care because of pregnant and postpartum women's potential vulnerabilities. The research protocol presents the aims to evaluate the prevalence of violence, the period(s) in which it occurs, aggressors and forms it takes as well as to explore how violence against women is perceived among pregnant and postpartum women.Methods and analysisThis mixed methods study protocol uses an explanatory sequential design and is based on the establishment of meta-inferences that result from the combination of quantitative and qualitative approaches. Probabilistic sampling will be used to select the study participants: 584 women attending prenatal and/or postpartum care outpatient services at the University of Campinas Women's Hospital, Brazil. The quantitative approach will consist of four validated questionnaires, and the qualitative approach will use focus groups that serve to deepen the understanding of participants' views about the study topic. To create the focus groups, 72 study participants will be invited and divided into 6 groups (3 adolescents and 3 adults) based on age and pregnancy/postpartum condition. Descriptive analysis of sociodemographic characteristics and questionnaire results will be used to identify the prevalence and forms of violence experienced by women during the pregnancy-puerperal cycle, the relationships between women and their aggressors, and the existence of a history of violence. A bivariate and multivariate analysis will be performed to identify the association between sociodemographic factors and violence as an outcome. Qualitative data will be analysed through Grounded Theory to understand women's perceptions of the phenomenon studied.Ethics and disseminationThe research protocol was approved by the Research Ethics Committee of the University of Campinas, Brazil number CAAE: 13426819.1.0000.5404. The results will be disseminated to the health science community.
