[PMID: 36215980 PMCID: PMC9839514 DOI: 10.1097/qai.0000000000003117] [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: 04/05/2022] [Accepted: 09/13/2022] [Indexed: 01/11/2023]
Abstract
BACKGROUND Prevention of mother-to-child transmission programs serve women continuing and initiating antiretroviral therapy (ART) in pregnancy, and follow-up schedules align to delivery rather than ART initiation, making conventional HIV retention measures (assessed from ART initiation) challenging to apply. We evaluated 3 measures of peripartum nonretention in Kenyan women living with HIV from pregnancy to 2 years postpartum. METHODS This longitudinal analysis used programmatic data from the Mobile WAChX trial (NCT02400671). Outcomes included loss to follow-up (LTFU) (no visit for ≥6 months), incomplete visit coverage (<80% of 3-month intervals with a visit), and late visits (>2 weeks after scheduled date). Predictors of nonretention were determined using Cox proportional hazards, log-binomial, and generalized estimating equation models. RESULTS Among 813 women enrolled at a median of 24 weeks gestation, incidence of LTFU was 13.6/100 person-years; cumulative incidence of LTFU by 6, 12, and 24 months postpartum was 16.7%, 20.9%, and 22.5%, respectively. Overall, 35.5% of women had incomplete visit coverage. Among 794 women with 12,437 scheduled visits, a median of 11.1% of visits per woman were late (interquartile range 4.3%-23.5%). Younger age, unsuppressed viral load, unemployment, ART initiation in pregnancy, and nondisclosure were associated with nonretention by all measures. Partner involvement was associated with better visit coverage and timely attendance. Women who became LTFU had higher frequency of previous late visits (16.7% vs. 7.7%, P < 0.0001). CONCLUSIONS Late visit attendance may be a sentinel indicator of LTFU. Identified cofactors of prevention of mother-to-child transmission programmatic retention may differ depending on retention measure assessed, highlighting the need for standardized measures.

Abstract
Background Nigeria has low antiretroviral therapy (ART) coverage among HIV-positive pregnant women. In a previous cluster-randomized trial in Nigeria, Baby Shower events resulted in higher HIV testing coverage and linkage of pregnant women to ART; here, we assess outcomes of Baby Shower events in a non-research setting. Methods Baby Shower events, including a prayer ceremony, group education, music, gifting of a “mama pack” with safe delivery supplies, and HIV testing with ART linkage support for HIV-positive pregnant women, were conducted in eighty sites in Benue State, Nigeria. Client questionnaires (including demographics, ANC attendance, and HIV testing history), HIV test results, and reported linkage to ART were analyzed. Descriptive data on HIV testing and ART linkage data for facility-based care at ANC clinics in Benue State were also analyzed for comparison. Results Between July 2016 and October 2017, 10,056 pregnant women and 6,187 male partners participated in Baby Shower events; 61.5% of women attended with a male partner. Nearly half of female participants (n = 4515, 44.9%) were not enrolled in ANC for the current pregnancy, and 22.3% (n = 2,241) of female and 24.8% (n = 1,532) of male participants reported they had never been tested for HIV. Over 99% (n = 16,240) of participants had their HIV status ascertained, with 7.2% of females (n = 724) and 4.0% of males (n = 249) testing HIV-positive, and 2.9% of females (n = 274) and 2.3% of males (n = 138) receiving new HIV-positive diagnoses. The majority of HIV-positive pregnant women (93.0%, 673/724) were linked to ART. By comparison, at health facilities in Benue State during a similar time period, 99.7% of pregnant women had HIV status ascertained, 8.4% had a HIV-positive status, 2.1% were newly diagnosed HIV-positive, and 100% were linked to ART. Conclusion Community-based programs such as the faith-based Baby Shower intervention complement facility-based approaches and can reach individuals who would not otherwise access facility-based care. Future Baby Showers implementation should incorporate enhanced support for ART linkage and retention to maximize the impact of this intervention on vertical HIV transmission.

Experiences, perceptions and potential impact of community-based mentor mothers supporting pregnant and postpartum women with HIV in Kenya: a mixed-methods study. J Int AIDS Soc 2021; 24:e25843. [PMID: 34797955 PMCID: PMC8604379 DOI: 10.1002/jia2.25843] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Accepted: 10/21/2021] [Indexed: 12/03/2022] Open
Abstract
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.

Community-facility linkage models and maternal and infant health outcomes in Malawi's PMTCT/ART program: A cohort study. PLoS Med 2021; 18:e1003780. [PMID: 34534213 PMCID: PMC8516224 DOI: 10.1371/journal.pmed.1003780] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 10/14/2021] [Accepted: 08/23/2021] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND In sub-Saharan Africa, 3 community-facility linkage (CFL) models-Expert Clients, Community Health Workers (CHWs), and Mentor Mothers-have been widely implemented to support pregnant and breastfeeding women (PBFW) living with HIV and their infants to access and sustain care for prevention of mother-to-child transmission of HIV (PMTCT), yet their comparative impact under real-world conditions is poorly understood. METHODS AND FINDINGS We sought to estimate the effects of CFL models on a primary outcome of maternal loss to follow-up (LTFU), and secondary outcomes of maternal longitudinal viral suppression and infant "poor outcome" (encompassing documented HIV-positive test result, LTFU, or death), in Malawi's PMTCT/ART program. We sampled 30 of 42 high-volume health facilities ("sites") in 5 Malawi districts for study inclusion. At each site, we reviewed medical records for all newly HIV-diagnosed PBFW entering the PMTCT program between July 1, 2016 and June 30, 2017, and, for pregnancies resulting in live births, their HIV-exposed infants, yielding 2,589 potentially eligible mother-infant pairs. Of these, 2,049 (79.1%) had an available HIV treatment record and formed the study cohort. A randomly selected subset of 817 (40.0%) cohort members underwent a field survey, consisting of a questionnaire and HIV biomarker assessment. Survey responses and biomarker results were used to impute CFL model exposure, maternal viral load, and early infant diagnosis (EID) outcomes for those missing these measures to enrich data in the larger cohort. We applied sampling weights in all statistical analyses to account for the differing proportions of facilities sampled by district. Of the 2,049 mother-infant pairs analyzed, 62.2% enrolled in PMTCT at a primary health center, at which time 43.7% of PBFW were ≤24 years old, and 778 (38.0%) received the Expert Client model, 640 (31.2%) the CHW model, 345 (16.8%) the Mentor Mother model, 192 (9.4%) ≥2 models, and 94 (4.6%) no model. Maternal LTFU varied by model, with LTFU being more likely among Mentor Mother model recipients (adjusted hazard ratio [aHR]: 1.45; 95% confidence interval [CI]: 1.14, 1.84; p = 0.003) than Expert Client recipients. Over 2 years from HIV diagnosis, PBFW supported by CHWs spent 14.3% (95% CI: 2.6%, 26.1%; p = 0.02) more days in an optimal state of antiretroviral therapy (ART) retention with viral suppression than women supported by Expert Clients. Infants receiving the Mentor Mother model (aHR: 1.24, 95% CI: 1.01, 1.52; p = 0.04) and ≥2 models (aHR: 1.44, 95% CI: 1.20, 1.74; p < 0.001) were more likely to undergo EID testing by age 6 months than infants supported by Expert Clients. Infants receiving the CHW and Mentor Mother models were 1.15 (95% CI: 0.80, 1.67; p = 0.44) and 0.84 (95% CI: 0.50, 1.42; p = 0.51) times as likely, respectively, to experience a poor outcome by 1 year than those supported by Expert Clients, but not significantly so. Study limitations include possible residual confounding, which may lead to inaccurate conclusions about the impacts of CFL models, uncertain generalizability of findings to other settings, and missing infant medical record data that limited the precision of infant outcome measurement. CONCLUSIONS In this descriptive study, we observed widespread reach of CFL models in Malawi, with favorable maternal outcomes in the CHW model and greater infant EID testing uptake in the Mentor Mother model. Our findings point to important differences in maternal and infant HIV outcomes by CFL model along the PMTCT continuum and suggest future opportunities to identify key features of CFL models driving these outcome differences.

Abstract
Nigeria contributes the highest to the global burden of HIV/AIDS and also accounts for the largest proportion of new vertically transmitted HIV infections among children. The Mentor Mothers program in the Nigerian Department of Defense was introduced in accordance with the World Health Organization and its implementing partner guidelines to curb the high incidence of vertically acquired HIV infections. Understanding the experiences of participants could serve as a gateway to evaluating the effectiveness of the program to better provide quality services within targeted health facilities. This qualitative study employed key informant interviews with six healthcare workers as well as two focus group discussions with six mentor mothers and six prevention of mother-to-child transmission (PMTCT) patients in four selected hospitals in the Nigerian Department of Defense to explore their experiences of the Mentor Mothers program. A thematic analysis technique was used to analyze the collated data. As a result, four main themes emerged, with the program perceived by most participants as providing psychosocial support to the patients, a valuable educational resource for raising HIV awareness, a valuable resource for promoting exclusive breastfeeding and mitigating vertical transmission of the virus, and functioning as a link between patients and the healthcare system. The participants reported that the program had effectively decreased HIV infections in children, reduced child and maternal mortality, and supported the livelihood and development of women, families, and communities in and around the Nigerian Department of Defense health facilities.

Abstract
A Community Health System Strengthening model, which mobilizes communities by applying quality improvement, was used in 39 communities around 3 health centers in Gaza Province, Mozambique, to increase identification of pregnant women and support them to attend antenatal care (ANC). This article describes the process and results. Community group representatives formed a community improvement team to spread messages about the importance of ANC, identify pregnant women, link them to the facility, and follow up. Between March 2014 and February 2015, teams identified 2020 pregnant women. Antenatal care attendance increased at all 3 centers. One health center did an additional chart review and found that postintervention, women were enrolling in care earlier in pregnancy. There were no changes in HIV testing or treatment initiation for HIV-positive women. Community-led improvement initiatives play an important role in connecting pregnant women with services to receive testing and treatment to promote optimal health and prevent HIV transmission.

Abstract
Background: The majority of global HIV infections in children under 10 years of age occur during pregnancy, delivery or breastfeeding, despite improved coverage of 'prevention of mother-to-child transmission' (PMTCT) guidelines to reduce vertical transmission. This article looks closer at one community-based peer mentorship programme [Mentor Mothers Zithulele (MMZ)] in the Eastern Cape, South Africa which aims to supplement the existing heavily burdened antenatal programmes and improve PMTCT care.Methods: Semi-structured interviews were undertaken with HIV-positive women participating in MMZ and women receiving standard PMTCT care without any intervention. A focus group discussion (FGD) was conducted with women working as Mentor mothers (MMs) for MMZ to explore their experience of the impact of peer mentoring on the rural communities they serve.Results: Six main themes were identified in the interviews with antenatal patients: (i) MMs were a key educational resource, (ii) MMs were important in promoting exclusive breastfeeding, (iii) encouraging early HIV testing during pregnancy and (iv) providing psychosocial support to patients in their homes, thereby reducing stigma and sense of alienation. Respondents requested (v) additional focus on HIV education. MMs can (vi) function as a link between patients and health-care providers, improving treatment adherence. During the FGD two themes emerged; MMs fill the gap between patients and health services, and MMZ should focus on HIV awareness and stigma reduction.Conclusion: Peer mentoring programmes can play an important role in reducing vertical HIV transmission in resource-limited, rural settings by providing participants with education, psychosocial support, and a continuum of care.

Effectiveness of Lifelong ART (Option B+) in the Prevention of Mother-to-Child Transmission of HIV Programme in Zambia: Observations Based on Routinely Collected Health Data. Front Public Health 2020; 7:401. [PMID: 32010656 PMCID: PMC6978742 DOI: 10.3389/fpubh.2019.00401] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2019] [Accepted: 12/16/2019] [Indexed: 11/29/2022] Open
Abstract
Background: Mother to child transmission of HIV (MTCT) is a global challenge affecting many countries especially in sub-Saharan Africa. In 2009 about 370,000 infants were infected with HIV mainly through MTCT and most of them in sub-Saharan Africa. We aimed to determine the effectiveness of Option B+ compared to other options in reducing rates of early MTCT of HIV infections in Zambia. Methods: This was a retrospective cohort study based on routinely collected data using SmartCare in Zambia. Survival analysis with Cox Proportional Hazard regression was used to determine association between MTCT and regimen type of mothers. Kaplan-Meier (K-M) curves were used to compare MTCT for infants born to mothers option B+ to those on other options, and Wilcoxon (Breslow) test was used to establish statistical significance. Results: Overall (n = 1,444), mother-baby pairs with complete data were included in the analysis, with the median age of mothers being 33 (28–38) years; and 57% of these women were on Option B+. MTCT rate was estimated at 5% (73/1,444) [P = 0.025]. A Kaplan-Meier estimate showed that HIV Exposed Infants (HEI) of mothers on Option B+ had lower MTCT rate than those who were on other MTCT prevention interventions [Wilcoxon test; chi2 = 4.97; P = 0.025]. Furthermore, The Nelson Aalen cumulative hazard estimates indicated similar evidence of option B+ being more effective than other options with some statistical significance [HR = 0.63, P = 0.068]. HEI of option B+ mothers had 50% reduced risk of having HIV infection compared to option A/B [adjusted HR = 0.4; 95% CI = 0.28–0.84; P = 0.010]. HEI to women who were married had an increased risk 50% of getting infected compared to those not married [adjusted HR = 1.5; 95% CI = 3.43–6.30; P < 0.001]. Exposed infants whose mothers had assisted delivery had 3 times increased risk of getting infected compared to those born through normal vaginal delivery [Adjusted HR = 3.2; 95% CI = 0.98–10.21; P = 0.050]. Conclusions: The use of Option B+ as PMTCT intervention was found to be more effective in reducing MTCT of HIV compared to other options. Scaling up access to life-long ART and improving retention for women on treatment can potentially reduce further vertical transmission.

Psaros C, Stanton AM, Bedoya CA, Mosery N, Evans S, Matthews LT, Haberer J, Vangel M, Safren S, Smit JA. Protocol for a prospective evaluation of postpartum engagement in HIV care among women living with HIV in South Africa. BMJ Open 2020; 10:e035465. [PMID: 31924641 PMCID: PMC6955573 DOI: 10.1136/bmjopen-2019-035465] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2019] [Revised: 11/27/2019] [Accepted: 11/28/2019] [Indexed: 01/06/2023] Open
Abstract
INTRODUCTION KwaZulu-Natal (KZN), South Africa (SA) has the highest prevalence of pregnant women living with HIV in the world. Pregnancy and the postpartum period offer opportunities to engage women in HIV care, to prevent perinatal transmission and to optimise maternal and infant well-being. However, research suggests that remaining engaged in HIV care during this time can be challenging. METHODS AND ANALYSIS We are conducting a 5-year prospective cohort study among pregnant women living with HIV in KZN to estimate the rates and factors associated with attrition from HIV care during this critical period. To determine who is most likely to fall out of care, we are examining a range of relevant variables informed by a socioecological model of HIV care, including individual, relational, community and healthcare system variables. We are enrolling 18-45-year-old women, at 28 weeks or more of pregnancy, who are living with HIV and currently taking antiretroviral therapies. Participants complete quantitative assessments at baseline (pregnancy) and at 6, 12, 18 and 24 months postpartum. A subset of women and their partners are invited to complete qualitative interviews to further explore their experiences in HIV care. The main study outcomes are suppressed HIV RNA and retention in care at each study assessment. Our understanding of the factors that drive postpartum attrition from HIV care will ultimately inform the development of interventions to facilitate continued engagement in postpartum HIV care. ETHICS AND DISSEMINATION This protocol has been approved by the Human Research Ethics Committee (Medical) at The University of the Witwatersrand (Johannesburg, SA) and the Partners Human Research Committee at Partners HealthCare (Boston, Massachusetts, USA). Site support and approval were obtained from the District Hospital and the KZN Provincial Department of Health. Results will be disseminated through peer-reviewed manuscripts, reports and both local and international presentations (Ethics Registration #170 212).

Acceptability of community-based mentor mothers to support HIV-positive pregnant women on antiretroviral treatment in western Kenya: a qualitative study. BMC Pregnancy Childbirth 2019; 19:288. [PMID: 31409297 PMCID: PMC6693232 DOI: 10.1186/s12884-019-2419-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2017] [Accepted: 07/19/2019] [Indexed: 12/05/2022] Open
Abstract
BACKGROUND Option B+ is a comprehensive antiretroviral treatment (ART) designed for HIV-infected pregnant/ postpartum women. However, barriers to implementing Option B+ and establishing long-term ART adherence while facilitating retention in prevention of mother to child transmission of HIV (PMTCT) services remain. Community-based mentor mothers (cMMs) who can provide home-based support for PMTCT services may address some of the barriers to successful adoption and retention in Option B+. Thus, we evaluated the acceptability of using cMMs as home-based support for PMTCT services. METHODS Gender-matched in-depth interviews were conducted between September-November 2014 for HIV-infected pregnant/postpartum women and their male partners living in southwestern Kenya (n = 40); additionally, we conducted four focus groups involving 30 health workers (n = 70) within four health facilities. Audio-recordings were transcribed, translated, and then coded using a thematic analytical approach in which data were deductively and inductively coded with support from prior literature, identified themes within the interview guides, and emerging themes from the transcripts utilizing Dedoose software. RESULTS Overall, the study results suggest high acceptability of cMMs among individual participants and health workers. Stigma reduction, improvement of utilization of health care services, as well as ART adherence were most frequently discussed potential benefits of cMMs. Participants pictured a cMM as someone acting as a role model and confidant, and who was over 30 years old. Many respondents raised concerns about breaches of confidentiality and inadvertent disclosure. Respondent suggestions to overcome these issues included the cMM working in different communities than where she lives and attending home-visits with no identifying clothing as an HIV-related health worker. CONCLUSIONS The home-based cMM approach may be a beneficial and acceptable strategy for promoting ART adherence and retention within PMTCT services for pregnant/postpartum women living with HIV. Considering the risks of inadvertent disclosure of HIV-infected status and related negative consequences for pregnant/postpartum women living with HIV, similar cMM program designs may benefit from recognizing and addressing these risks. TRIAL REGISTRATION The MOTIVATE! study was registered on July 7, 2015 at the ClinicalTrials.gov ( NCT02491177 ).

Muzyamba C. Local people's views on the evidence-based skilled-maternal-care in Mfuwe, Zambia: a qualitative study. BMC Pregnancy Childbirth 2019; 19:135. [PMID: 31014279 PMCID: PMC6480803 DOI: 10.1186/s12884-019-2282-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Accepted: 04/04/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND There is growing demand for high quality evidence-based practice in the fight against negative maternal health outcomes in Sub-Saharan Africa (SSA). Zambia is one of the countries that has transposed this evidence-based approach by outlawing Traditional Birth Attendants (TBAs) and recommending exclusive skilled-care. There is division among scholars regarding the usefulness of this approach to maternal health in SSA in general. One strand of scholars praises the approach and the other criticizes it. However, there is still lack of evidence to legitimize either of the two positions in poor-settings. Thus the aim of this study is to fill this gap by investigating local people's views on the evidence-based practice in the form of skilled-maternal-care in Zambia, by using Mfuwe as a case study. METHODS With the help of the Social Representation theory, Focus Group Discussions (FGDs) were conducted in Mfuwe, Zambia with 63 participants. FINDINGS The study shows that the evidence-based strategy (of exclusive skilled-care) led to improved quality of care in cases where it was accessible. However, not all women had access to skilled-care; thus the act of outlawing the only alternative form of care (TBAs) seemed to have been counterproductive in the context of Mfuwe. The study therefore demonstrates that incorporating TBAs rather than obscuring them may offer an opportunity for improving their potential benefits and minimizing their limitations thereby increasing access and quality of care to women of Mfuwe. CONCLUSION This study illustrates that while evidence-based strategies remain useful in improving maternal care, they need to be carefully appropriated in poor settings in order to increase access and quality of care.

Abstract
Introduction: The advent of policies promoting lifelong antiretroviral therapy (ART) for all pregnant and postpartum women living with HIV has shifted focus from short-term prevention of mother-to-child transmission (PMTCT) to lifelong engagement in ART services. However, disengagement from care threatens the long-term treatment and prevention benefits of lifelong ART. Areas covered: A framework for considering the unique aspects of ART for pregnant and postpartum women is presented along with a review of the literature on maternal engagement in care in sub-Saharan Africa and a discussion of potential interventions to sustain engagement in lifelong ART. Expert opinion: Engaging women and mothers in ART services for life is critical for maternal health, PMTCT, and prevention of sexual transmission. Evidence-based interventions exist to support engagement in care but most focus on periods of mother-to-child transmission risk. In the long term, life transitions and health-care transfers are inevitable. Thus, interventions that can reach beyond a single facility or provide a bridge between health services should be prioritized. Multicomponent interventions will also be essential to address the numerous intersecting barriers to sustained engagement in ART services.

Effectiveness of a Lay Counselor-Led Combination Intervention for Retention of Mothers and Infants in HIV Care: A Randomized Trial in Kenya. J Acquir Immune Defic Syndr 2019; 80:56-63. [PMID: 30399035 PMCID: PMC6319592 DOI: 10.1097/qai.0000000000001882] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2018] [Accepted: 09/27/2018] [Indexed: 11/26/2022]
Abstract
BACKGROUND Retention of mothers and infants across the prevention of mother-to-child HIV transmission (PMTCT) continuum remains challenging. We assessed the effectiveness of a lay worker administered combination intervention compared with the standard of care (SOC) on mother-infant attrition. METHODS HIV-positive pregnant women starting antenatal care at 10 facilities in western Kenya were randomized using simple randomization to receive individualized health education, retention/adherence support, appointment reminders, and missed visit tracking vs. routine care per guidelines. The primary endpoint was attrition of mother-infant pairs at 6 months postpartum. Attrition was defined as the proportion of mother-infant pairs not retained in the clinic at 6 months postpartum because of mother or infant death or lost to follow-up. Intent-to-treat analysis was used to assess the difference in attrition. This trial is registered with ClinicalTrials.gov; NCT01962220. RESULTS From September 2013 to June 2014, 361 HIV-positive pregnant women were screened, and 340 were randomized to the intervention (n = 170) or SOC (n = 170). Median age at enrollment was 26 years (interquartile range 22-30); median gestational age was 24 weeks (interquartile range 17-28). Overall attrition of mother-infant pairs was 23.5% at 6 months postpartum. Attrition was significantly lower in the intervention arm compared with SOC (18.8% vs. 28.2%, relative risk (RR) = 0.67, 95% confidence interval: 0.45 to 0.99, P = 0.04). Overall, the proportion of mothers who were retained and virally suppressed (<1000 copies/mL) at 6 months postpartum was 54.4%, with no difference between study arms. CONCLUSIONS Provision of a combination intervention by lay counselors can decrease attrition along the PMTCT cascade in low-resource settings.

Abstract
Background Mother to child transmission of HIV (MTCT) still remains a challenge affecting many countries. Globally, an estimated 150,000 children were newly infected with HIV in 2015, over 90% of them in Sub-Saharan Africa through MTCT. In Zambia approximately 500,000 babies are born and 40,000 acquire the infection vertically if there is no intervention annually. This study estimated the HIV testing coverage and associated factors among Zambian women of reproductive age 15–49 years. Methods A cross-sectional study based on data extracted from the Zambia Demographics and Health Survey [Zambia Demographic and Health Survey. Central Statistical Office (CSO), Ministry of Health (MOH), Tropical Diseases Research Centre (TDRC), University of Zambia, and Macro International Inc. 2009. 2014]. Women aged 15–49 years, 15,388 who reported having ever tested for HIV or not comprised the de facto eligible sample. Extracted data comprised women’s demographic characteristics; their full birth history and records of antenatal care for the most recent birth within a 5 year period preceding the survey. A weighted multiple logistic regression model was done to determine factors associated with the odds of HIV testing coverage among women of reproductive age. Results Out of 15,388 women in the study, 12,413 (81%) reported ever tested for HIV. Of the 6461 women who attended antenatal care (ANC) 6139 (95%) reported ever tested for HIV. Additionally, 6139 (95%) out of 6461 of the women were given information on PMTCT during ANC sessions. Testing coverage was higher among women aged 20–24 years compared to women aged 15–19 years [AOR 2.1, 95% CI 1.14–3.84; p = 0.017]. Women with higher socio-economic status had 6.6 times the odds of having ever tested compared to women with lower status [AOR 6.6, 95% CI 3.04–14.14; p < 0.001]. Conclusions In this study we have demonstrated that HIV testing coverage is higher among women of reproductive age. HIV testing among women attending ANC is also higher. Older women with higher socio-economic status are more likely to take up HIV testing compared to their young counterparts.

Abstract
BACKGROUND Community Health Workers (CHWs) provide basic health screening and advice to members of their own communities. Although CHWs are trained, no CHW programmes have used a formal method to identify the level of achievement on post-training assessments that distinguishes "safe" from "unsafe". Objectives: The aim of this study was to use Ebel method of standard setting for a post-training written knowledge assessment for CHWs in Neno, Malawi. METHODS 12 participants agreed the definitions of a "just-deployment ready" and an "ideal" CHW. Participants rated the importance and difficulty of each question on a three-point scale and also indicated the proportion of "just-deployment ready" CHWs expected to answer each of the nine question types correctly. Mean scores were used to determine the passing standard, which was reduced by one standard error of measurement (SEM) as this was the first time any passing standard had been employed.The level of agreement across participants' ratings of importance and difficulty was calculated using Krippendorf's alpha. The assessment results from the first cohort of CHW trainees were analysed using classical test theory. FINDINGS There was poor agreement between participants on item ratings of both importance and difficulty (Krippendorf's alphas of 0.064 and 0.074 respectively). The pass mark applied to the assessment, following adjustment using the SEM, was 53.3%. Based on this pass mark, 68% of 129 CHW trainees were 'clear passes', 11% 'borderline passes', 9% 'borderline fails' and 12% 'clear fails'. CONCLUSIONS Determining whether a CHW is deployment-ready is an important, but difficult exercise, as evidenced by a lack of agreement regarding question importance and difficulty. Future exercises should allow more time for training, discussion and modification of ratings. Based on the assessment, most CHWs trained could be considered deployment-ready, but following-up their performance in the field will be vital to validate the pass mark set.

Front Public Health 2018; 6:192. [PMID: 30155454 PMCID: PMC6102411 DOI: 10.3389/fpubh.2018.00192] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Accepted: 06/22/2018] [Indexed: 11/19/2022] Open
Abstract
Background: Globally, an estimated 150,000 children were newly infected with HIV in 2015, over 90% of them in Sub-Saharan Africa. In Zambia, ~500,000 babies are born to HIV positive mothers every year, and without intervention 40,000 of them would acquire the infection. Studies have shown a strong association between education and HIV prevalence, but in Zambia, this association has not been demonstrated. There is little published information on the association between educational attainment and HIV testing uptake among pregnant women, which is fundamental in understanding the mother to child transmission of HIV. This study investigated whether educational attainment was associated with uptake of HIV testing among women of reproductive age in Zambia. Methods: Data were taken from Zambia Demographic and Health Survey in 2014 (ZDHS14). The analysis consisted of all women aged 15–49 years, who responded to the question on HIV testing in the ZDHS. Multivariable logistic regression was used to determine whether educational attainment was associated with uptake of HIV testing among women of reproductive age in Zambia. Results: Educational attainment was strongly associated with HIV testing among 15,388 women of child bearing age [AOR 3.8, 95% CI 1.7–8.2; p = 0.001]. HIV testing differed greatly by socioeconomic social status with an increased uptake among women with higher wealth index [AOR 4.4, 95% CI 1.9–9.9; p = 0.001]. Additionally, HIV testing was observed to be higher among the older women 25–34 years compared to the young women 15–19 years [AOR 2.3, 95% CI 1.3–4.3; p = 0.007]. Conclusions: This study revealed educational attainment to be a strong predictor of HIV testing among women of child bearing age in this population. High HIV testing uptake among educated pregnant women indicated that low-educated women may not fully realize the benefits of testing for HIV. Therefore, strengthening HIV testing in rural health facilities and providing initiatives to overcome barriers to testing among women with no formal education may help reduce vertical transmission of HIV.

Outcomes of HIV-infected children have improved dramatically over the past decade, but are undermined by patient loss to follow-up (LTFU). We assessed patterns of LTFU among HIV-infected children receiving antiretroviral treatment (ART) at a large inner-city HIV clinic in Johannesburg, South Africa between 2005 and 2014.Demographic and clinical data were extracted from clinic records of children under 12 years. Differences between characteristics of children retained in care and LTFU were assessed using Wilcoxon rank sum tests or Pearson χ tests. Cox proportional hazard models then identified characteristics associated with LTFU.Of 135 children, the median age at ART initiation was 21.5 months (IQR: 6.3-47.7) with a median follow-up time of 3.3 years (IQR: 1.4-5.0). The incidence rate of LTFU was 10.8 per 100 person-years (95% CI: 8.2-14.4); cumulatively 36% of children were LTFU. Almost a third (n = 39) of children missed a clinic visit, but then returned to care; 77% of these were eventually LTFU. In total, 18% of children had elevated viral loads after 6 or more months of ART. Older age at ART initiation (18-59 months: aHR 1.6, 95% CI: 3.9-14.2) and ever missing a clinic visit (aHR 7.4 95% CI: 3.9-14.2) were independent predictors of LTFU.High rates of LTFU were observed in this primary care clinic. Risks for LTFU included older age (>18 months old) and missed clinic visits. Identifying children who miss scheduled visits and developing strategies directed at retaining them in care is critical to improving long-term pediatric HIV outcomes.

The role of community volunteers in PMTCT programme: Lessons from selected sites in Zambia to strengthen health education on infant feeding and follow-up of HIV-positive mother-infant pair. Afr J Prim Health Care Fam Med 2018; 10:e1-e8.

Abstract
Background A global debate surrounding health care delivery at the lowest level of the community has aroused interest among researchers. In settings where skilled health workforce is scarce, the community relies on volunteers to provide care. Aim To explore the role of community-based volunteers (CBVs) and their perspectives on human immunodeficiency virus (HIV) and infant feeding to gain insights into the implementation of prevention of mother-to-child transmission (PMTCT) interventions at community level. Setting The study was conducted in Lusaka using Ngombe and Chelstone health facilities to recruit participants. Fieldwork took place from January 2014 to September 2014. Methods An exploratory descriptive qualitative study employing focus group discussions was conducted with CBVs. Convenient sampling was used to recruit 10 participants from each site. All transcribed interviews were imported into the Nvivo 10 for open coding and analysis. Results Although the role of community volunteers was to support and teach mothers on infant feeding in relation to HIV, the known cultural norms and practices had a bearing on how they tailored their information on breastfeeding to mothers. However, their link of the community to the health facilities cannot be overemphasised in these settings. Conclusion The role of community volunteers in PMTCT interventions can be strengthened by improving their training through use of appropriate educational materials and support of required resources. Lessons from these sites can inform future research to design community-based interventions and develop health education materials that are sensitive to cultural norms and practices in this and similar settings.

Abstract
Introduction Increasing access to HIV-related care and treatment for children aged 0–18 years in resource-limited settings is an urgent global priority. In 2011–2012 the percentage increase in children accessing antiretroviral therapy was approximately half that of adults (11 vs. 21 %). We propose a model for increasing access to, and retention in, paediatric HIV care and treatment in resource-limited settings. Methods Following a rapid appraisal of recent literature seven main challenges in paediatric HIV-related care and treatment were identified: (1) lack of regular, integrated, ongoing HIV-related diagnosis; (2) weak facility-based systems for tracking and retention in care; (3) interrupted availability of dried blood spot cards (expiration/stock outs); (4) poor quality control of rapid HIV testing; (5) supply-related gaps at health facility-laboratory interface; (6) poor uptake of HIV testing, possibly relating to a fatalistic belief about HIV infection; (7) community-associated reasons e.g. non-disclosure and weak systems for social support, resulting in poor retention in care. Results To increase sustained access to paediatric HIV-related care and treatment, regular updating of Policies, review of inter-sectoral Plans (at facility and community levels) and evaluation of Programme implementation and impact (at national, subnational, facility and community levels) are non-negotiable critical elements. Additionally we recommend the intensified implementation of seven main interventions: (1) update or refresher messaging for health care staff and simple messaging for key staff at early childhood development centres and schools; (2) contact tracing, disclosure and retention monitoring; (3) paying particular attention to infant dried blood spot (DBS) stock control; (4) regular quality assurance of rapid HIV testing procedures; (5) workshops/meetings/dialogues between health facilities and laboratories to resolve transport-related gaps and to facilitate return of results to facilities; (6) community leader and health worker advocacy at creches, schools, religious centres to increase uptake of HIV testing and dispel fatalistic beliefs about HIV; (7) use of mobile communication technology (m-health) and peer/community supporters to maintain contact with patients. Discussion and Conclusion We propose that this package of facility, community and family-orientated interventions are needed to change the trajectory of the paediatric HIV epidemic and its associated patterns of morbidity and mortality, thus achieving the double dividend of improving HIV-free survival.

Abstract
Introduction Partners In Health and the Malawi Ministry of Health collaborate on comprehensive HIV services in Neno, Malawi, featuring community health workers, interventions addressing social determinants of health and health systems strengthening. We conducted an observational study to describe the HIV care continuum in Neno and to compare facility-level HIV outcomes against health facilities nationally. Methods We compared facility-level outcomes in Neno (n=13) with all other districts (n=682) from 2013 to 2015 using mixed-effects linear regression modelling. We selected four outcomes that are practically useful and roughly mapped on to the 90-90-90 targets: facility-based HIV screenings relative to population, new antiretroviral therapy (ART)enrolments relative to population, 1-year survival rates and per cent retained in care at 1 year. Results In 2013, the average number of HIV tests performed, as a per cent of the adult population, was 11.75%, while the average newly enrolled patients was 10.03%. Percent receiving testing increased by 4.23% over 3 years (P<0.001, 95% CI 2.98% to 5.49%), while percent enrolled did not change (P=0.28). These results did not differ between Neno and other districts (P=0.52), despite Neno having a higher proportion of expected patients enrolled. In 2013, the average ART 1-year survival was 80.41% nationally and 91.51% in Neno, which is 11.10% higher (P=0.002, 95% CI 4.13% to 18.07%). One-year survival declined by 1.75% from 2013 to 2015 (P<0.001, 95% CI −2.61% to −0.89%); this was similar in Neno (P=0.83). Facility-level 1-year retention was 85.43% nationally in 2013 (P<0.001, 95% CI 84.2% to 86.62%) and 12.07% higher at 97.50% in Neno (P=0.001, 95% CI 5.08% to19.05%). Retention declined by 2.92% (P<0.001, 95% CI −3.69% to −2.14%) between 2013 and 2015, both nationally and in Neno. Conclusion The Neno HIV programme demonstrated significantly higher survival and retention rates compared with all other districts in Malawi. Incorporating community health workers, strengthening health systems and addressing social determinants of health within the HIV programme may help Malawi and other countries accelerate progress towards 90-90-90.

Lay health worker experiences administering a multi-level combination intervention to improve PMTCT retention. BMC Health Serv Res 2018; 18:17.

Abstract
BACKGROUND The recent scale-up of prevention of mother-to-child transmission of HIV (PMTCT) services has rapidly accelerated antiretroviral therapy (ART) uptake among pregnant and postpartum women in sub-Saharan Africa. The Mother and Infant Retention for Health (MIR4Health) study evaluates the impact of a combination intervention administered by trained lay health workers to decrease attrition among HIV-positive women initiating PMTCT services and their infants through 6 months postpartum. METHODS This was a qualitative study nested within the MIR4Health trial. MIR4Health was conducted at 10 health facilities in Nyanza, Kenya from September 2013 to September 2015. The trial intervention addressed behavioral, social, and structural barriers to PMTCT retention and included: appointment reminders via text and phone calls, follow-up and tracking for missed clinic visits, PMTCT health education at home visits and during clinic visits, and retention and adherence support and counseling. All interventions were administered by lay health workers. We describe results of a nested small qualitative inquiry which conducted two focus groups to assess the experiences and perceptions of lay health workers administering the interventions. Discussions were recorded and simultaneously transcribed and translated into English. Data were analyzed using framework analysis approach. RESULTS Study findings show lay health workers played a critical role supporting mothers in PMTCT services across a range of behavioral, social, and structural domains, including improved communication and contact, health education, peer support, and patient advocacy and assistance. Findings also identified barriers to the uptake and implementation of the interventions, such as concerns about privacy and stigma, and the limitations of the healthcare system including healthcare worker attitudes. Overall, study findings indicate that lay health workers found the interventions to be feasible, acceptable, and well received by clients. CONCLUSIONS Lay health workers played a fundamental role in supporting mothers engaged in PMTCT services and provided valuable feedback on the implementation of PMTCT interventions. Future interventions must include strategies to ensure client privacy, decrease stigma within communities, and address the practical limitations of health systems. This study adds important insight to the growing body of research on lay health worker experiences in HIV and PMTCT care. TRIAL REGISTRATION Clinicaltrials.gov NCT01962220 .

Delivery arrangements for health systems in low-income countries: an overview of systematic reviews. Cochrane Database Syst Rev 2017; 9:CD011083. [PMID: 28901005 PMCID: PMC5621087 DOI: 10.1002/14651858.cd011083.pub2] [Citation(s) in RCA: 49] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/28/2022]
Abstract
BACKGROUND Delivery arrangements include changes in who receives care and when, who provides care, the working conditions of those who provide care, coordination of care amongst different providers, where care is provided, the use of information and communication technology to deliver care, and quality and safety systems. How services are delivered can have impacts on the effectiveness, efficiency and equity of health systems. This broad overview of the findings of systematic reviews can help policymakers and other stakeholders identify strategies for addressing problems and improve the delivery of services. OBJECTIVES To provide an overview of the available evidence from up-to-date systematic reviews about the effects of delivery arrangements for health systems in low-income countries. Secondary objectives include identifying needs and priorities for future evaluations and systematic reviews on delivery arrangements and informing refinements of the framework for delivery arrangements outlined in the review. METHODS We searched Health Systems Evidence in November 2010 and PDQ-Evidence up to 17 December 2016 for systematic reviews. We did not apply any date, language or publication status limitations in the searches. We included well-conducted systematic reviews of studies that assessed the effects of delivery arrangements on patient outcomes (health and health behaviours), the quality or utilisation of healthcare services, resource use, healthcare provider outcomes (such as sick leave), or social outcomes (such as poverty or employment) and that were published after April 2005. We excluded reviews with limitations important enough to compromise the reliability of the findings. Two overview authors independently screened reviews, extracted data, and assessed the certainty of evidence using GRADE. We prepared SUPPORT Summaries for eligible reviews, including key messages, 'Summary of findings' tables (using GRADE to assess the certainty of the evidence), and assessments of the relevance of findings to low-income countries. MAIN RESULTS We identified 7272 systematic reviews and included 51 of them in this overview. We judged 6 of the 51 reviews to have important methodological limitations and the other 45 to have only minor limitations. We grouped delivery arrangements into eight categories. Some reviews provided more than one comparison and were in more than one category. Across these categories, the following intervention were effective; that is, they have desirable effects on at least one outcome with moderate- or high-certainty evidence and no moderate- or high-certainty evidence of undesirable effects. Who receives care and when: queuing strategies and antenatal care to groups of mothers. Who provides care: lay health workers for caring for people with hypertension, lay health workers to deliver care for mothers and children or infectious diseases, lay health workers to deliver community-based neonatal care packages, midlevel health professionals for abortion care, social support to pregnant women at risk, midwife-led care for childbearing women, non-specialist providers in mental health and neurology, and physician-nurse substitution. Coordination of care: hospital clinical pathways, case management for people living with HIV and AIDS, interactive communication between primary care doctors and specialists, hospital discharge planning, adding a service to an existing service and integrating delivery models, referral from primary to secondary care, physician-led versus nurse-led triage in emergency departments, and team midwifery. Where care is provided: high-volume institutions, home-based care (with or without multidisciplinary team) for people living with HIV and AIDS, home-based management of malaria, home care for children with acute physical conditions, community-based interventions for childhood diarrhoea and pneumonia, out-of-facility HIV and reproductive health services for youth, and decentralised HIV care. Information and communication technology: mobile phone messaging for patients with long-term illnesses, mobile phone messaging reminders for attendance at healthcare appointments, mobile phone messaging to promote adherence to antiretroviral therapy, women carrying their own case notes in pregnancy, interventions to improve childhood vaccination. Quality and safety systems: decision support with clinical information systems for people living with HIV/AIDS. Complex interventions (cutting across delivery categories and other health system arrangements): emergency obstetric referral interventions. AUTHORS' CONCLUSIONS A wide range of strategies have been evaluated for improving delivery arrangements in low-income countries, using sound systematic review methods in both Cochrane and non-Cochrane reviews. These reviews have assessed a range of outcomes. Most of the available evidence focuses on who provides care, where care is provided and coordination of care. For all the main categories of delivery arrangements, we identified gaps in primary research related to uncertainty about the applicability of the evidence to low-income countries, low- or very low-certainty evidence or a lack of studies.

Abstract
The recognition and fulfilment of the sexual and reproductive health and rights (SRHR) of all individuals and couples affected by HIV, including HIV-serodiscordant couples, requires intervention strategies aimed at achieving safe and healthy pregnancies and preventing undesired pregnancies. Reducing risk of horizontal and vertical transmission and addressing HIV-related infertility are key components of such interventions. In this commentary, we present challenges and opportunities for achieving safe pregnancies for serodiscordant couples through a social ecological lens. At the individual level, knowledge (e.g. of HIV status, assisted reproductive technologies) and skills (e.g. adhering to antiretroviral therapy or pre-exposure prophylaxis) are important. At the couple level, communication between partners around HIV status disclosure, fertility desires and safer pregnancy is required. Within the structural domain, social norms, stigma and discrimination from families, community and social networks influence individual and couple experiences. The availability and quality of safer conception and fertility support services within the healthcare system remains essential, including training for healthcare providers and strengthening integration of SRHR and HIV services. Policies, legislation and funding can improve access to SRHR services. A social ecological framework allows us to examine interactions between levels and how interventions at multiple levels can better support HIV-serodiscordant couples to achieve safe pregnancies. Strategies to achieve safer pregnancies should consider interrelated challenges at different levels of a social ecological framework. Interventions across multiple levels, implemented concurrently, have the potential to maximize impact and ensure the full SRHR of HIV-serodiscordant couples.

Abstract
INTRODUCTION Timely, accurate and affordable testing algorithms at point-of-care are critical for early infant HIV diagnosis and initiation of antiretroviral therapy in the postpartum period. We aimed to assess the utility of HIV rapid tests for young, breast-fed HIV-exposed infants in resource limited, high HIV burden settings. MATERIALS AND METHODS We collected data on the performance of 2 commonly used rapid tests (Determine and Unigold) in Malawi between 2008 and 2012 or at the University of North Carolina between 2014 and 2015. For each 3-month interval between ages 3 and 18 months, we calculated the sensitivity, specificity, positive and negative predictive values of each test compared with the HIV DNA/RNA PCR gold standard. We also assessed the utility of each rapid test to diagnose incident HIV infection during the breastfeeding period. RESULTS Among 121 HIV-exposed infants who were negative at age 6 weeks, 21 (17.2%) became infected by 18 months. At 3 months of age, both rapid tests had minimal clinical value with specificity values of 7.0% [95% confidence interval (CI): 2.3-15.7] for Determine and 19.4% (95% CI: 11.1-30.5) for Unigold. Starting at age 6 and 9 months, the Unigold test could be used as a screening tool in the follow-up of HIV-exposed infants with specificity values of 83.7% (95% CI: 74.4-89.9) and 97.7% (95% CI: 94.6-99.7), respectively. Starting at age 12 months, the type of test became less important as both tests performed well in identifying HIV-free children, although both tests failed to detect some incident HIV infections. CONCLUSIONS Updated guidelines for the use of rapid tests in young HIV-exposed children that explicitly take type of test and infant age into account are urgently needed to ensure optimal care for the 1.5 million HIV-exposed infants born annually.

Abstract
In 2013, physician-researchers announced that a baby in Mississippi had been 'functionally cured' of HIV [Persaud, D., Gay, H., Ziemniak, C. F., Chen, Y. H., Piatak, M., Chun, T.-W., … Luzuriaga, K. (2013b, March). Functional HIV cure after very early ART of an infected infant. Paper presented at the 20th conference on retroviruses and opportunistic infections, Atlanta, GA]. Though the child later developed a detectable viral load, the case remains unprecedented, and trials to build on the findings are planned [National Institute of Allergy and Infectious Diseases. (2014). 'Mississippi baby' now has detectable HIV, researchers find. Retrieved from http://www.niaid.nih.gov/news/newsreleases/2014/pages/mississippibabyhiv.aspx ]. Whether addressing HIV 'cure' or 'remission', scrutiny of this case has focused largely on scientific questions, with only introductory attention to ethics. The social inequalities and gaps in care that made the discovery possible - and their ethical implications for paediatric HIV remission - have gone largely unexamined. This paper describes structural inequalities surrounding the 'Mississippi baby' case and a parallel case in South Africa, where proof-of-concept studies are in the early stages. We argue that an ethical programme of research into infant HIV remission ought to be 'structurally competent', and recommend that paediatric remission studies consider including a research component focused on social protection and barriers to care.

Factors Associated with PMTCT Cascade Completion in Four African Countries. AIDS Res Treat 2016; 2016:2403936. [PMID: 27872760 PMCID: PMC5107823 DOI: 10.1155/2016/2403936] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2016] [Revised: 09/07/2016] [Accepted: 10/10/2016] [Indexed: 01/25/2023] Open
Abstract
Background. Many countries are working to reduce or eliminate mother-to-child transmission (MTCT) of HIV. Prevention efforts have been conceptualized as steps in a cascade but cascade completion rates during and after pregnancy are low. Methods. A cross-sectional survey was performed across 26 communities in Cameroon, Cote d'Ivoire, South Africa, and Zambia. Women who reported a pregnancy within two years were enrolled. Participant responses were used to construct the PMTCT cascade with all of the following steps required for completion: at least one antenatal visit, HIV testing performed, HIV testing result received, initiation of maternal prophylaxis, and initiation of infant prophylaxis. Factors associated with cascade completion were identified using multivariable logistic regression modeling. Results. Of 976 HIV-infected women, only 355 (36.4%) completed the PMTCT cascade. Although most women (69.2%) did not know their partner's HIV status; awareness of partner HIV status was associated with cascade completion (aOR 1.4, 95% CI 1.01–2.0). Completion was also associated with receiving an HIV diagnosis prior to pregnancy compared with HIV diagnosis during or after pregnancy (aOR 14.1, 95% CI 5.2–38.6). Conclusions. Pregnant women with HIV infection in Africa who were aware of their partner's HIV status and who were diagnosed with HIV before pregnancy were more likely to complete the PMTCT cascade.

Schuster RC, de Sousa O, Rivera J, Olson R, Pinault D, Young SL. Performance-based incentives may be appropriate to address challenges to delivery of prevention of vertical transmission of HIV services in rural Mozambique: a qualitative investigation. HUMAN RESOURCES FOR HEALTH 2016; 14:60. [PMID: 27717388 PMCID: PMC5054578 DOI: 10.1186/s12960-016-0157-0] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2016] [Accepted: 09/27/2016] [Indexed: 06/01/2023]
Abstract
BACKGROUND Performance-based incentives (PBIs) have garnered global attention as a promising strategy to improve healthcare delivery to vulnerable populations. However, literature gaps in the context in which an intervention is implemented and how the PBIs were developed exist. Therefore, we (1) characterized the barriers and promoters to prevention of vertical transmission of HIV (PVT) service delivery in rural Mozambique, where the vertical transmission rate is 12 %, and (2) assessed the appropriateness for a PBI's intervention and application to PVT. METHODS We conducted 24 semi-structured interviews with nurses, volunteers, community health workers, and traditional birth attendants about the barriers and promoters they experienced delivering PVT services. We then explored emergent themes in subsequent focus group discussions (n = 7, total participants N = 92) and elicited participant perspectives on PBIs. The ecological motivation-opportunity-ability framework guided our iterative data collection and thematic analysis processes. RESULTS The interviews revealed that while all health worker cadres were motivated intrinsically and by social recognition, they were dissatisfied with low and late remuneration. Facility-based staff were challenged by factors across the rest of the ecological levels, primarily in the opportunity domain, including the following: poor referral and record systems (work mandate), high workload, stock-outs, poor infrastructure (facility environment), and delays in obtaining patient results and donor payment discrepancies (administrative). Community-based cadres' opportunity challenges included lack of supplies, distance (work environment), lack of incorporation into the health system (administration), and ability challenges of incorrect knowledge (health worker). PBIs based on social recognition and that enable action on intrinsic motivation through training, supervision, and collaboration were thought to have the most potential for targeting improvements in record and referral systems and better integrating community-based health workers into the health system. Concerns about the implementation of incentives included neglect of non-incentivized tasks and distorted motivation among colleagues. CONCLUSIONS We found that highly motivated health workers encountered severe opportunity challenges in their PVT mandate. PBIs have the potential to address key barriers that facility- and community-based health workers encounter when delivering PVT services, specifically by building upon existing intrinsic motivation and leveraging highly valued social recognition. We recommend a controlled intervention to monitor incentives' effects on worker motivation and non-incentivized tasks to generate insights about the feasibility of PBIs to improve the delivery of PVT services.

Retention in Care among HIV-Infected Pregnant Women in Haiti with PMTCT Option B. AIDS Res Treat 2016; 2016:6284290. [PMID: 27651953 PMCID: PMC5019862 DOI: 10.1155/2016/6284290] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2016] [Revised: 07/28/2016] [Accepted: 08/03/2016] [Indexed: 01/08/2023] Open
Abstract
Background. Preventing mother-to-child transmission of HIV relies on engagement in care during the prenatal, peripartum, and postpartum periods. Under PMTCT Option B, pregnant women with elevated CD4 counts are provided with antiretroviral prophylaxis until cessation of breastfeeding. Methods. Retrospective analysis of retention in care among HIV-infected pregnant women in Haiti was performed. Logistic regression was used to identify risk factors associated with loss to follow-up (LFU) defined as no medical visit for at least 6 months and Kaplan-Meier curves were created to show LFU timing. Results. Women in the cohort had 463 pregnancies between 2009 and 2012 with retention rates of 80% at delivery, 67% at one year, and 59% at 2 years. Among those who were LFU, the highest risk period was during pregnancy (60%) or shortly afterwards (24.4% by 12 months). Never starting on antiretroviral therapy (aRR 2.29, 95% CI 1.4–3.8) was associated with loss to follow-up. Conclusions. Loss to follow-up during and after pregnancy was common in HIV-infected women in Haiti under PMTCT Option B. Since sociodemographic factors and distance from home to facility did not predict LFU, future work should elicit and address barriers to retention at the initial prenatal care visit in all women. Better tracking systems to capture engagement in care in the wider network are needed.

Abstract
PURPOSE OF REVIEW To propose a prevention of mother-to-child transmission (PMTCT) care continuum that defines the programmatic steps necessary to provide HIV care to the HIV-infected pregnant woman and her infant during the risk period for HIV transmission. RECENT FINDINGS There are several complexities of PMTCT care that should be considered in the care continuum, including the evolution in the population of women entering PMTCT care, various models of PMTCT service delivery and patterns of PMTCT care, and the critical step of transfer of women's HIV care from PMTCT programs to adult HIV clinics. SUMMARY We propose a reconceptualized PMTCT care continuum that accounts for the complexities of PMTCT care. We also propose a combined outcome for pregnant women and their infants across an interlinked PMTCT continuum to measure both maternal and child health outcomes.

Abstract
BACKGROUND Few effective community-based interventions exist to increase HIV testing and uptake of antiretroviral therapy (ART) in pregnant women in hard-to-reach resource-limited settings. We assessed whether delivery of an intervention through churches, the Healthy Beginning Initiative, would increase uptake of HIV testing in pregnant women compared with standard health facility referral. METHODS In this cluster randomised trial, we enrolled self-identified pregnant women aged 18 years and older who attended churches in southeast Nigeria. We randomised churches (clusters) to intervention or control groups, stratified by mean annual number of infant baptisms (<80 vs ≥80). The Healthy Beginning Initiative intervention included health education and on-site laboratory testing implemented during baby showers in intervention group churches, whereas participants in control group churches were referred to health facilities as standard. Participants and investigators were aware of church allocation. The primary outcome was confirmed HIV testing. This trial is registered with ClinicalTrials.gov, identifier number NCT 01795261. FINDINGS Between Jan 20, 2013, and Aug 31, 2014, we enrolled 3002 participants at 40 churches (20 per group). 1309 (79%) of 1647 women attended antenatal care in the intervention group compared with 1080 (80%) of 1355 in the control group. 1514 women (92%) in the intervention group had an HIV test compared with 740 (55%) controls (adjusted odds ratio 11·2, 95% CI 8·77-14·25; p<0·0001). INTERPRETATION Culturally adapted, community-based programmes such as the Healthy Beginning Initiative can be effective in increasing HIV screening in pregnant women in resource-limited settings.

Trials 2016; 17:88. [PMID: 26883307 PMCID: PMC4754877 DOI: 10.1186/s13063-016-1202-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2015] [Accepted: 01/28/2016] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND Efforts to scale up and improve programs for prevention of mother-to-child transmission of HIV (PMTCT) have focused primarily at the health facility level, and limited attention has been paid to defining an effective set of community interventions to improve demand and uptake of services and retention. Many barriers to PMTCT are also barriers to pregnancy, childbirth, and postnatal care faced by mothers regardless of HIV status. Demand for maternal and child health (MCH) and PMTCT services can be limited by critical social, cultural, and structural barriers. Yet, rigorous evaluation has shown limited evidence of effectiveness of multilevel community-wide interventions aimed at improving MCH and HIV outcomes for pregnant women living with HIV. We propose to assess the effect of a package of multilevel community interventions: a social learning and action component, community dialogues, and peer-led discussion groups, on the demand for, uptake of, and retention of HIV positive pregnant/postpartum women in MCH/PMTCT services. METHODS/DESIGN This study will undertake a three-arm randomized trial in Swaziland, Uganda, and Zimbabwe. Districts/regions (n = 9) with 45 PMTCT-implementing health facilities and their catchment areas (populations 7,300-27,500) will be randomly allocated to three intervention arms: 1) community leader engagement, 2) community leader engagement with community days, or 3) community leader engagement with community days and male and female community peer groups. The primary study outcome is HIV exposed infants (HEIs) returning to the health facility within 2 months for early infant diagnosis (EID) of HIV. Secondary study outcomes include gestational age of women attending for first antenatal care, male partners tested for HIV, and HEIs receiving nevirapine prophylaxis at birth. Changes in community knowledge, attitudes, practices, and beliefs on MCH/PMTCT will be assessed through household surveys. DISCUSSION Implementation of the protocol necessitated changes in the original study design. We purposively selected facilities in the districts/regions though originally the study clusters were to be randomly selected. Lifelong antiretroviral therapy for all HIV positive pregnant and lactating women, Option B+, was implemented in the three countries during the study period, with the potential for a differential impact by study arm. Implementation however, was rapidly done across the districts/regions, so that there is unlikely be this potential confounding. We developed a system of monitoring and documentation of potential confounding activities or actions, and these data will be incorporated into analyses at the conclusion of the project. Strengthens of the study are that it tests multilevel interventions, utilizes program as well as study specific and individual data, and it is conducted under "real conditions" leading to more robust findings. Limitations of the protocol include the lack of a true control arm and inadequate control for the potential effect of Option B+, such as the intensification of messages as the importance of early ANC and male partner testing.

Abstract
BACKGROUND The integration of antiretroviral therapy (ART) services into antenatal care for prevention of mother-to-child transmission has resulted in the need to transfer HIV-infected women to general ART clinics after delivery. Transfer of patients on ART between services may present a challenge to adherence and retention, but there are few data describing this step in the HIV care cascade for women starting ART in pregnancy. METHODS We described postpartum transfer of care in a cohort of women initiating ART during pregnancy and referred from integrated antenatal ART services to general ART clinics. Engagement in ART care at general ART clinics was assessed through routine laboratory records and telephonic interviews. RESULTS Overall, 279 postpartum women were transferred to ART clinics. By 5 months postreferral, between 74% and 91% of women had evidence of engagement at an ART clinic depending on the outcome definition. In a log-binomial model adjusted for age, CD4 cell count and being diagnosed with HIV in the current pregnancy, additional months on ART before delivery improved the likelihood of engagement in an ART clinic (relative risk: 1.05, 95% confidence interval: 1.00 to 1.09, P = 0.036). CONCLUSIONS Postpartum transfer of ART care is an important and previously neglected step in the HIV care cascade for pregnant women. Even in this cohort of highly adherent women up to 25% did not remain in care after transfer. Retention is required across all steps of the cascade, including transfer of ART care after delivery, to maximize the benefits of ART for both maternal and child health.

Tracing defaulters in HIV prevention of mother-to-child transmission programmes through community health workers: results from a rural setting in Zimbabwe. J Int AIDS Soc 2015; 18:20022.

Abstract
Introduction High retention in care is paramount to reduce vertical human immunodeficiency virus (HIV) infections in prevention of mother-to-child transmission (PMTCT) programmes but remains low in many sub-Saharan African countries. We aimed to assess the effects of community health worker–based defaulter tracing (CHW-DT) on retention in care and mother-to-child HIV transmission, an innovative approach that has not been evaluated to date. Methods We analyzed patient records of 1878 HIV-positive pregnant women and their newborns in a rural PMTCT programme in the Tsholotsho district of Zimbabwe between 2010 and 2013 in a retrospective cohort study. Using binomial regression, we compared vertical HIV transmission rates at six weeks post-partum, and retention rates during the perinatal PMTCT period (at delivery, nevirapine [NVP] initiation at three days post-partum, cotrimoxazole (CTX) initiation at six weeks post-partum, and HIV testing at six weeks post-partum) before and after the introduction of CHW-DT in the project. Results Median maternal age was 27 years (inter-quartile range [IQR] 23 to 32) and median CD4 count was 394 cells/µL3 (IQR 257 to 563). The covariate-adjusted rate ratio (aRR) for perinatal HIV transmission was 0.72 (95% confidence intervals [95% CI] 0.27 to 1.96, p=0.504), comparing patient outcomes after and before the intervention. Among fully retained patients, 11 (1.9%) newborns tested HIV positive. ARRs for retention in care were 1.01 (95% CI 0.96 to 1.06, p=0.730) at delivery; 1.35 (95% CI 1.28 to 1.42, p<0.001) at NVP initiation; 1.78 (95% CI 1.58 to 2.01, p<0.001) at CTX initiation; and 2.54 (95% CI 2.20 to 2.93, p<0.001) at infant HIV testing. Cumulative retention after and before the intervention was 496 (85.7%) and 1083 (87.3%) until delivery; 480 (82.9%) and 1005 (81.0%) until NVP initiation; 303 (52.3%) and 517 (41.7%) until CTX initiation; 272 (47.0%) and 427 (34.4%) until infant HIV testing; and 172 (29.7%) and 405 (32.6%) until HIV test result collection. Conclusions The CHW-DT intervention did not reduce perinatal HIV transmission significantly. Retention improved moderately during the post-natal period, but cumulative retention decreased rapidly even after the intervention. We showed that transmission in resource-limited settings can be as low as in resource-rich countries if patients are fully retained in care. This requires structural changes to the regular PMTCT services, in which community health workers can, at best, play a complementary role.

Abstract
BACKGROUND Success in prevention of mother-to-child transmission (PMTCT) raises the prospect of eliminating pediatric HIV infection. To achieve global elimination, however, strategies are needed to strengthen PMTCT interventions. This study aimed to determine PMTCT outcomes and identify challenges facing its successful implementation in a rural setting in Kenya. METHODS A retrospective cohort design was used. Routine demographic and clinical data for infants and mothers enrolling for PMTCT care at a rural hospital in Kenya were analysed. Cox and logistic regression were used to determine factors associated with retention and vertical transmission respectively. RESULTS Between 2006 and 2012, 1338 infants were enrolled and followed up for PMTCT care with earlier age of enrollment and improved retention observed over time. Mother to child transmission of HIV declined from 19.4 % in 2006 to 8.9 % in 2012 (non-parametric test for trend p = 0.024). From 2009 to 2012, enrolling for care after 6 months of age, adjusted Odds Ratio [aOR]: 23.3 [95 % confidence interval (CI): 8.3-65.4], presence of malnutrition ([aOR]: 2.3 [95 % CI: 1.1-5.2]) and lack of maternal use of highly active antiretroviral therapy (HAART) (aOR: 6.5 [95 % CI: 1.4-29.4]) was associated with increased risk of HIV infection. Infant's older age at enrollment, malnutrition and maternal HAART status, were also associated with drop out from care. Infants who were not actively followed up were more likely to drop out from care (adjusted Hazard Ratio: 6.6 [95 % CI: 2.9-14.6]). DISCUSSION We report a temporal increase in the proportion of infants enrolling for PMTCT care before 3 months of age, improved retention in PMTCT and a significant reduction in the proportion of infants enrolled who became HIV-infected, emphasizing the benefits of PMTCT. CONCLUSION A simple set of risk factors at enrollment can identify mother-infant pairs most at risk of infection or drop out for targeted intervention.

Abstract
BACKGROUND Many HIV-infected pregnant women identified during antenatal care (ANC) do not enroll in long-term HIV care, resulting in deterioration of maternal health and continued risk of HIV transmission to infants. METHODS We performed a cluster randomized trial to evaluate the effect of integrating HIV care into ANC clinics in rural Kenya. Twelve facilities were randomized to provide either integrated services (ANC, prevention of mother-to-child transmission, and HIV care delivered in the ANC clinic; n = 6 intervention facilities) or standard ANC services (including prevention of mother-to-child transmission and referral to a separate clinic for HIV care; n = 6 control facilities). RESULTS There were high patient attrition rates over the course of this study. Among study participants who enrolled in HIV care, there was 12-month follow-up data for 256 of 611 (41.8%) women and postpartum data for only 325 of 1172 (28%) women. By 9 months of age, 382 of 568 (67.3%) infants at intervention sites and 338 of 594 (57.0%) at control sites had tested for HIV [odds ratio (OR) 1.45, 95% confidence interval (CI): 0.71 to 2.82]; 7.3% of infants tested HIV positive at intervention sites compared with 8.0% of infants at control sites (OR 0.89, 95% CI: 0.56 to 1.43). The composite clinical/immunologic progression into AIDS was similar in both arms (4.9% vs. 5.1%, OR 0.83, 95% CI: 0.41 to 1.68). CONCLUSIONS Despite the provision of integrated services, patient attrition was substantial in both arms, suggesting barriers beyond lack of service integration. Integration of HIV services into the ANC clinic was not associated with a reduced risk of HIV transmission to infants and did not appear to affect short-term maternal health outcomes.

Abstract
INTRODUCTION The Chinese government has invested US$140 million annually on prevention of mother-to-child transmission (PMTCT) of HIV. This study evaluates the programme by examining the improvements in programme coverage HIV testing and provision of antiviral drugs along the PMTCT cascade. METHODS Data for PMTCT cascade indicators were collected through a comprehensive systematic review of published peer-reviewed English and Chinese literature during 2003-2011. Meta-analysis was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS This study included 113 publications. HIV prevalence among pregnant women in China who accessed antenatal care (ANC) remained below 0.1% during the past decade. HIV testing coverage in pregnant women attending ANC and in HIV-exposed infants at 18 months significantly increased from 62.4% (95% CI 4.7% to 98.2%) and 22.1% (16.3% to 32.3%) in 2003 to 90.3% (88.4% to 91.8%) and 82.8% (66.9% to 99.5%) in 2011 respectively, whereas antiretroviral (ARV) prophylaxis uptake increased from 35.2% (12.2% to 47.3%) and 26.9% (24.3% to 28.9%) to 86.2% (53.2% to 97.2%) and 90.3% (85.5% to 93.7%). HIV vertical transmission rate substantially decreased from 31.8% (25.7% to 38.6%) prior to the programme to 2.3% (1.4% to 3.8%) in 2011. During 2003-2011, among 25,312 (23,995-26,644) infants born to HIV-positive mothers who received ARV prophylaxis, 975 (564-1395) were diagnosed with HIV, corresponding to an average transmission rate of 3.9% (3.2% to 4.6%). However, while including transmissions among HIV-positive pregnant women who were lost along the cascade, the average transmission rate during 2003-2011 was 17.4% (15.8% to 19.0%). CONCLUSIONS PMTCT programmes have reduced HIV mother-to-child transmission in China. Further improvements in the continuum of care remain essential in realising the full potential of the programme.

HUMAN RESOURCES FOR HEALTH 2015; 13:12.

Abstract
INTRODUCTION Close-to-community (CTC) providers, including community health workers or volunteers or health extension workers, can be effective in promoting access to and utilization of health services. Tasks are often shifted to these providers with limited resources and support from CTC programmes or communities. The Community Health System Strengthening (CHSS) model is part of an improvement approach which draws on existing formal and informal networks within a community, such as agricultural or women's groups, to support CTC providers and address gaps in community-based health services. The model offers a framework for bringing representatives from existing community networks, CTC providers, and health facility staff together to form a community team charged with identifying challenges in service delivery, testing solutions, and monitoring changes. CTC providers draw upon fellow community team members to disseminate health messages and refer community members in need of services. CASES Two cases are presented. In Ethiopia, the CHSS model was applied in 18 communities to increase HIV testing among pregnant women and antenatal care service utilization and improve sanitation. Prior to implementation, representatives from community groups were unaware of health extension workers or were uncomfortable making referrals. By participating on the community team, representatives became familiar with and comfortable referring people to health extension workers and spreading health messages. During implementation, more pregnant women registered for antenatal care and tested for HIV; health extension workers conducted more postnatal visits; and more households had functioning latrines and proper latrine use increased. In Tanzania, the CHSS model was applied in five communities to improve HIV testing and retention into care. Community team members talked to their families and social networks about HIV testing and, when they identified someone who had dropped out of treatment, they referred those individuals to the home-based care volunteer. Increases in HIV testing and a reduction in patients lost to follow-up were observed. DISCUSSION AND CONCLUSION The CHSS model brings together existing networks within communities to support and lend legitimacy to CTC providers. This approach may result in sustainable community-based programmes, especially in HIV where the continuum of care extends beyond the facility and into the community.

Abstract
Despite strong evidence that antiretroviral therapy (ART) reduces the risk of mother-to-child transmission of HIV and improves the health of HIV-positive mothers, many HIV-positive pregnant women do not enrol into long-term HIV care and treatment. This study examined barriers and facilitators to the linkage of HIV-positive pregnant women from antenatal care (ANC) to long-term HIV care from patient and provider perspectives, following the implementation of a collaborative quality improvement project in Eastern Uganda. It also solicited recommendations for improving linkages to HIV care. Structured interviews were conducted with 11 health providers and 48 HIV-positive mothers enrolled in HIV care. Facilitators to linking HIV-positive pregnant women to long-term HIV care identified included support from expert clients, escorted referrals, same-day HIV care registration, and coordination between ANC and HIV services. Barriers reported included shortages in HIV testing kits and fear of social, physical and medical consequences. Participants recommended integration of ANC and HIV services, reduction in waiting times, HIV counselling by expert clients, and community-based approaches for improving linkages to HIV care. Linking HIV-positive pregnant women to HIV care can be improved through deliberate implementation of quality improvement interventions in facilities to address barriers to access and provide stronger support and community mobilisation.

Abstract
Increased access to testing and treatment means HIV can be managed as a chronic illness, though successful management requires continued engagement with the health care system. Most of the global HIV burden is in sub-Saharan Africa where rates of new infections are consistently higher in women versus men. Pregnancy is often the point at which an HIV diagnosis is made. While preventing mother to child transmission (PMTCT) interventions significantly reduce the rate of vertical transmission of HIV, women must administer ARVs to their infants, adhere to breastfeeding recommendations, and test their infants for HIV after childbirth. Some women will be expected to remain on the ARVs initiated during pregnancy, while others are expected to engage in routine testing so treatment can be reinitiated when appropriate. The postpartum period presents many barriers to sustained treatment adherence and engagement in care. While some studies have examined adherence to postpartum PMTCT guidelines, few have focused on continued engagement in care by the mother, and very few examine adherence beyond the 6-week postpartum visit. Here, we attempt to identify gaps in the research literature and make recommendations on how to address barriers to ongoing postpartum HIV care.

Abstract
BACKGROUND Despite an estimated 59,000 incident pediatric HIV infections in 2012 in Nigeria, rates of early infant diagnosis (EID) of HIV service uptake remain low. We evaluated maternal factors independently associated with EID uptake in rural North Central Nigeria. METHODS We performed a cohort study using HIV/AIDS program data of HIV-infected pregnant women enrolled into HIV care/treatment on or before December 31, 2012 (n = 712). We modeled the probability of initiation of EID using multivariable logistic regression. RESULTS Three hundred fifty-seven HIV-infected pregnant women enrolled their infants in EID across the 4 study sites. Women who enrolled their infants in EID vs. those who did not were similar across age, occupation, referral source, and select laboratory variables. Clinic of enrollment and date of enrollment were strong predictors for EID entry (P < 0.001). Women enrolled more recently were less likely to have their infants undergo EID than those enrolled at the beginning of the project (January 2011 vs. January 2010, adjusted odds ratio = 0.35, 95% confidence interval: 0.22 to 0.56; January 2012 vs. January 2010, adjusted odds ratio = 0.30, 95% confidence interval: 0.14 to 0.61). Women who received care in the more urban setting of Umaru Yar Adua Hospital were more likely to have their infants enrolled in EID than those who received care in the other 3 clinics. CONCLUSIONS HIV-infected women in our prevention of mother-to-child HIV transmission program were more likely to bring in their infants for EID if they were enrolled in a more urbanized clinic location, and if they presented during an earlier phase of the program. The need for more intensive family engagement and program quality improvement is apparent, especially in rural settings.

Abstract
BACKGROUND There is an increasing push for 'evidence-based' decision making in global health policy circles. However, at present there are no agreed upon standards or guidelines for how to evaluate evidence in global health. Recent evaluations of existing evidence frameworks that could serve such a purpose have identified details of program context and project implementation as missing components needed to inform policy. We performed a pilot study to assess the current state of reporting of context and implementation in studies of global health interventions. METHODS We identified three existing criteria sets for implementation reporting and selected from them 10 criteria potentially relevant to the needs of policy makers in global health contexts. We applied these 10 criteria to 15 articles included in the evidence base for three global health interventions chosen to represent a diverse set of advocated global health programs or interventions: household water chlorination, prevention of mother-to-child transmission of HIV, and lay community health workers to reduce child mortality. We used a good-fair-poor/none scale for the ratings. RESULTS The proportion of criteria for which reporting was poor/none ranged from 11% to 54% with an average of 30%. Eight articles had 'good' or 'fair' documentation for greater than 75% of criteria, while five articles had 'poor or none' documentation for 50% of criteria or more. Examples of good reporting were identified. CONCLUSIONS Reporting of context and implementation information in studies of global health interventions is mostly fair or poor, and highly variable. The idiosyncratic variability in reporting indicates that global health investigators need more guidance about what aspects of context and implementation to measure and how to report them. This lack of context and implementation information is a major gap in the evidence needed by global health policy makers to reach decisions.

Abstract
INTRODUCTION Access to lifesaving prevention of mother-to-child transmission (PMTCT) services is problematic in rural Zambia. The simplest intervention used in Zambia has been 2-dose nevirapine (NVP) administration in the peripartum period, a regimen of 1 NVP tablet to the mother at the onset of labor and 1 dose in the form of syrup to the newborn within 4 to 72 hours after birth. This 2-dose regimen has been shown to reduce MTCT by nearly 50%. We set out to demonstrate that in-home HIV testing and NVP dosing by traditional birth attendants (TBAs) is feasible and acceptable by women in rural Zambia. METHODS This was a pilot program using TBAs to perform rapid saliva-based HIV testing and administer single-dose NVP in tablet form to the mother at the onset of labor and syrup to the infant after birth. RESULTS A total of 280 pregnant women were consented and enrolled into the program, of whom 124 (44.3%) gave birth at home with the assistance of a trained TBA. Of those, 16 (12.9%) were known to be HIV positive, and 101 of the remaining 108 (93.5%) accepted a rapid HIV test. All these women tested HIV negative. In the subset of 16 mothers who were HIV positive, 13 (81.3%) took single-dose NVP administered by a TBA between 1 and 24 hours prior to birth and 100% of exposed newborns (16 of 16) received NVP syrup within 72 hours after birth, 80% of whom were dosed in the first 24 hours of life. DISCUSSION With the substantial shortage of human resources in public health care throughout sub-Saharan Africa, it is extremely valuable to utilize lay health care workers to help extended services beyond the level of the facility. Given the high uptake of PMTCT services we believe that TBAs with proper training and support can successfully provide country-approved PMTCT.

Abstract
Background To achieve the goal of United Nations of elimination of new HIV infections, a program of prevention of mother-to-child transmission (PMTCT) was launched in Guangdong province. The objective of this study is to evaluate the effectiveness of the PMTCT program. Methods The retrospective cross-section analysis was conducted using the data of case reported cards of HIV positive mothers and their infants from 2007 to 2010 in Guangdong province, and 108 pairs of eligible subjects were obtained. We described the data and compared the rates of MTCT by various PMTCT interventions respectively. Results The overall rate of HIV MTCT was 13.89% (15) among 108 pairs of HIV positive mothers and their infants; 60.19% (65) of the mothers ever received ARVs, 80.56% (87) of infants born to HIV positive mothers ever received ARVs, but 16.67% (18) of the mothers and infants neither received ARVs. Among all the mothers and infants, who both received ARVs, received triple ARVs, mother received ARVs during pregnancy, and both received ARVs and formula feeding showed the lower rates of HIV MTCT, and the rates were 8.06%, 2.50%, 5.77%, and 6.67% respectively. In infants born to HIV positive mother, who received mixed feeding had a higher HIV MTCT up to 60.00%. Delivery mode might not relative to HIV MTCT. Conclusions The interventions of PMTCT program in Guangdong could effectively reduce the rate of HIV MTCT, but the effectiveness of the PMTCT program were heavily cut down by the lower availability of the PMTCT interventions.

Abstract
OBJECTIVE To evaluate the effect of home visits by community health workers (CHWs) on maternal and infant well being from pregnancy through the first 6 months of life for women living with HIV (WLH) and all neighborhood mothers. DESIGN AND METHODS In a cluster randomized controlled trial in Cape Town townships, neighborhoods were randomized within matched pairs to either standard care, comprehensive healthcare at clinics (n=12 neighborhoods; n=169 WLH; n=594 total mothers); or Philani Intervention Program, home visits by CHWs in addition to standard care (PIP; n=12 neighborhoods; n=185 WLH; n=644 total mothers). Participants were assessed during pregnancy (2% refusal) and reassessed at 1 week (92%) and 6 months (88%) postbirth. We analyzed PIP's effect on 28 measures of maternal and infant well being among WLH and among all mothers using random effects regression models. For each group, PIP's overall effectiveness was evaluated using a binomial test for correlated outcomes. RESULTS Significant overall benefits were found in PIP compared to standard care among WLH and among all participants. Secondarily, compared to standard care, PIP WLH were more likely to complete tasks to prevent vertical transmission, use one feeding method for 6 months, avoid birth-related medical complications, and have infants with healthy height-for-age measurements. Among all mothers, compared to standard care, PIP mothers were more likely to use condoms consistently, breastfeed exclusively for 6 months, and have infants with healthy height-for-age measurements. CONCLUSION PIP is a model for countries facing significant reductions in HIV funding whose families face multiple health risks.

Lesotho's minimum PMTCT package: lessons learned for combating vertical HIV transmission using co-packaged medicines. J Int AIDS Soc 2012; 15:17326. [PMID: 23273267 PMCID: PMC3531330 DOI: 10.7448/ias.15.2.17326] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2012] [Revised: 09/27/2012] [Accepted: 12/05/2012] [Indexed: 11/20/2022] Open
Abstract
Introduction Mother-to-child transmission of HIV can be reduced to<5% with appropriate antiretroviral medications. Such reductions depend on multiple health system encounters during antenatal care (ANC), delivery and breastfeeding; in countries with limited access to care, transmission remains high. In Lesotho, where 28% of women attending ANC are HIV positive but where geographic and other factors limit access to ANC and facility deliveries, a Minimum PMTCT Package was launched in 2007 as an alternative to the existing facility-based approach. Distributed at the first ANC visit, it packaged together all necessary pregnancy, delivery and early postnatal antiretroviral medications for mother and infant. Methods To examine the availability, feasibility, acceptability and possible negative consequences of the Minimum PMTCT Package, data from a 2009 qualitative and quantitative study and a 2010 facility assessment were used. To examine the effects on ANC and facility-based delivery rates, a difference-in-differences analytic approach was applied to 2009 Demographic and Health Survey data for HIV-tested women who gave birth before and after Minimum PMTCT Package implementation. Results The Minimum PMTCT Package was feasible and acceptable to providers and clients. Problems with test kit and medicine stock-outs occurred, and 46% of women did not receive the Minimum PMTCT Package until at least their second ANC visit. Providing adequate instruction on the use of multiple medications represented a challenge. The proportion of HIV-positive women delivering in facilities declined after Minimum PMTCT Package implementation, although it increased among HIV-negative women (difference-in-differences=14.5%, p=0.05). The mean number of ANC visits declined more among HIV-positive women than among HIV-negative women after implementation, though the difference was not statistically significant (p=0.09). Changes in the percentage of women receiving≥4 ANC visits did not differ between the two groups. Conclusions If supply issues can be resolved and adequate client educational materials provided, take-away co-packages have the potential to increase access to PMTCT commodities in countries where women have limited access to health services. However, efforts must be made to carefully monitor potential changes in ANC visits and facility deliveries, and further evaluation of adherence, safety and effectiveness are needed.
