Uptake and outcomes of a prevention-of mother-to-child transmission (PMTCT) program in Zomba district, Malawi

Infant and Young Child Feeding in the Context of HIV: An Exploration of Barriers in Exclusive Breastfeeding Practice in Dar Es Salaam, Tanzania

Background

Ensuring optimal nutrition through early breastfeeding is vital for infant mental development and overall health. HIV infections complicate decisions regarding exclusive breastfeeding, jeopardizing effective infant and young child feeding, which affects nutrition and health outcomes. Recognizing the lack of evidence on barriers to infant feeding in the context of HIV in Tanzania, this study was conducted to explore individual, household, and community obstacles in the Ilala district, Dar es Salaam.

Methods

The study used a hospital-based qualitative approach, focusing on HIV-positive mothers with infants aged 3-6 months in Dar es Salaam city. This involved reviewing mothers' files, conducting interviews with them, and interviewing Reproductive and Child Health clinics (RCH) and community healthcare providers. In total, 27 In-depth interviews were conducted until data saturation was reached, and thematic analysis was used to analyze collected data.

Findings

The study identified various barriers to exclusive breastfeeding, encompassing individual factors like work schedules, postpartum depression, and breast conditions. On the household level, barriers included limited access to resources, family influence, and HIV status disclosure reluctance due to stigma. In the community, low retention in the Prevention of Mother-to-Child Transmission (PMTCT) programs plays a pivotal role in hindering exclusive breastfeeding support for HIV-positive mothers.

Conclusion and Recommendations

HIV-positive mothers face diverse barriers ranging from individual, household, and community-based barriers. Policies supporting breastfeeding, early detection of postnatal depression and breast problems, and peer support for young mothers are of paramount importance. Food insecurity and HIV stigma should be tackled through income-generating activities, family involvement in PMTCT programs, and awareness campaigns. Community-based counselors play a crucial role in supporting HIV-positive mothers in their exclusive breastfeeding journey to improve PMTCT care retention.

Healthcare Workers' Knowledge of HIV-Exposed Infant Feeding Options and Infant Feeding Counseling Practice in Northern Nigeria

BACKGROUND

Despite the existence of evidence-based HIV-exposed infant feeding guidelines, infants in Africa still acquire HIV through inappropriate feeding practices.

OBJECTIVE

To identify predictors of HIV-exposed infant feeding knowledge and counseling practice among health care workers (HCW) in Nigeria.

METHODS

Structured, pretested questionnaires were administered to HCW (n=262) in a tertiary health facility in Kano, Nigeria. Multivariate logistic regression was used to determine predictors of HIV-exposed infant feeding knowledge and counseling practice.

RESULTS

Of 262 respondents, (58.0%, n=152) had good knowledge of recommended feeding options. Respondents listed exclusive breastfeeding (57.6%, n=151), human milk substitutes (45.4%, n=119), HIV-negative wet-nursing (37.0%, n=97), heated expressed human milk (20.6%, n=54) and mixed feeding (13.4%, n=35) as appropriate feeding choices. Over half (57.3%, n=150) of the respondents have ever counseled a HIV-positive mother on infant feeding. Knowledge was predicted by female sex (Adjusted Odds Ratio (AOR)=2.47, 95% Confidence Interval (CI):1.35-4.52), profession (physician vs. laboratory scientist, AOR=4.00, 95%CI:1.25-12.87; nurse/midwife vs. laboratory scientist, AOR=2.75, 95%CI:1.17-9.28), infant feeding counseling training (AOR=3.27, 95%CI:1.87-5.71), and number of children (2-4 vs. 0, AOR=1.75, 95%CI:1.23-3.92). Infant feeding counseling was predicted by female sex (AOR=2.85, 95%CI:1.39-5.85), age (>40 vs. <30 years, AOR=3.87, 95%CI:1.27-15.65), knowledge of infant feeding options (good vs. fair/poor, AOR=3.96, 95%CI:2.07-7.59), training (AOR=2.60, 95%CI:1.42-5.32), and profession (physician vs. laboratory scientist, AOR=10.7, 95%CI:2.85-40.54; nurse/midwife vs. laboratory scientist, AOR=4.8, 95%CI:1.26-18.02).

CONCLUSION

The practice of infant feeding counseling among HCW in Nigeria is associated with sex, knowledge, and profession. Our findings may inform the development of targeted training programs for HCW in similar settings.

What influences uptake and early adherence to Option B+ (lifelong antiretroviral therapy among HIV positive pregnant and breastfeeding women) in Central Uganda? A mixed methods study

Background

High uptake and optimal adherence to Option B+ antiretroviral therapy (ART) increase effectiveness in averting mother-to-child transmission of HIV. Option B+ ART uptake, early adherence, and associated factors need to be evaluated in Central Uganda.

Methods

A mixed approaches study was carried out in six health facilities in Masaka, Mityana, and Luwero districts from October 2013 to February 2016. Questionnaires were administered to 507 HIV positive pregnant females seeking antenatal care services. Key informant interviews were conducted with 54 health providers, and in-depth interviews (IDIs) with 57 HIV positive women on Option B+ ART. Quantitative data were analyzed using log-binomial regression model to determine factors associated with optimal adherence (taking at least 95% of the prescribed ART), while thematic analysis was used on qualitative data.

Results

Ninety one percent of women (463/507) received a prescription of life long ART. Of these, 93.3% (432/463) started swallowing their medicines. Overall, 83% of women who received ART prescriptions (310/374) felt they were ready to initiate ART immediately. Main motivating factors to swallow ART among those who received a prescription were women’s personal desire to be healthy (92.3%) and desire to protect their babies (90.6%). Optimal adherence to ART was achieved by 76.8% (315/410). Adherence was higher among females who were ready to start ART (adj. PR = 3.20; 95% CI: 1.15–8.79) and those who had revealed their HIV positive result to someone (adj. PR = 1.23; 95% CI: 1.04–1.46). Facilitators of ART uptake from qualitative findings included adequate counseling, willingness to start, and knowing the benefits of ART. Reasons for refusal to start ART included being unready to start ART, fear to take ART for life, doubt of HIV positive results, and preference for local herbs. Reasons for non-adherence were travelling far away from health facilities, fear of side effects, non-disclosure of HIV results to anyone, and perception that the baby is safe from HIV infection post-delivery.

Conclusions

Uptake of Option B+ ART was very high. However, failure to start swallowing ART and sub-optimal adherence are a major public health concern. Enhancing women’s readiness to start ART and encouraging HIV result revelation could improve ART uptake and adherence.

Mortality and Loss to Follow-Up Among HIV-Exposed Infants After Option B+ Guideline Implementation in Amhara Regional State Referral Hospitals, Ethiopia

Background: Prevention of mother-to-child transmission of HIV program (PMTCT) is a comprehensive approach that aimed for the wellbeing of all HIV-infected women, to prevent new HIV infection among infants born to HIV-positive mothers, and providing management for HIV-positive women and infants. Nevertheless, there was considerably high attrition within the prevention of mother-to-child transmission programs that was merely because of loss to follow-up (LTFU) followed by mortality. In resource-limited countries, one-third of infected children die before 1 year, and more than half of them die before 2 years. The aim of this study was to assess the prevalence or incidence of mortality and LTFU among infants born from HIV-positive mothers in the Amhara regional state referral hospitals, Ethiopia. Methods: This study was conducted in five Amhara regional state referral hospitals' prevention of mother-to-child transmission departments. A simple random sampling technique with proportional allocation was used to assess the outcomes of 221 exposed infants. A retrospective cohort design was used in selecting the 221 exposed infants' document from the referral hospitals of the region, Amhara. The exposed infants' profiles were documented between January 1, 2014 and May 30, 2017. Results: This study described attritions (death and loss-to-follow-up) of exposed babies in PMTCT departments of Amhara regional state referral hospitals in Ethiopia. In this study, low LTFU with zero death was reported. Residence, immunization status of babies, and place of delivery were independent factors of LTFU. Conclusions: The cumulative incidence of mortality in this study was zero. This assured that the recommended option is substantial for the elimination of HIV-caused death in 2030 as per WHO plan. However, the cumulative incidence of LTFU was not zero.

Level of quality of option B+PMTCT service provision in public health facilities in Mekelle zone, northern Ethiopia: cross-sectional study

Background

Substantial improvements have been observed in coverage and access to maternal health services in Ethiopia. However, the quality of care has been lagging behind. Therefore, this study aimed to assess the level of quality of Option B⁺ PMTCT in Northern Ethiopia.

Methods

A facility based survey was conducted from February to April 2016 in Northern Ethiopia. Twelve health facilities were enrolled in the study. Mixed method approach was used in line with Donabedian (Input- Process-Output) service quality assessment model. Data of 168 HIV positive mothers & their infant were abstracted from registers, and follow up charts. During the Option B+ service consultation, a total of 60 sessions were involved for direct observation. Of which, 30 clients and 12 service providers were subjected for exit and in-depth interview respectively. Facilities were categorized rendering good service quality based on predetermined quality judgment criteria. Reasons of good and bad service quality were thematically fitted with each quality component based on emerging themes (TM1-TM3), and categories (CA1-CA6).

Results

Of the total 12 study health facilities, 2(16.7%) were achieved the desired level of service quality based on the three quality components. The input quality was better and judged as good in 33.3% health facilities. However; process and output service quality were realized in one - fourth of them.

Conclusion

Insignificant numbers of facilities fulfilled the aspired level of service quality. Quality of care was found influenced by multiple inputs, processes, and output related barriers and facilitators. Comprehensive Program monitoring is needed based on three quality components to improve the overall service quality.

Protocol for a prospective evaluation of postpartum engagement in HIV care among women living with HIV in South Africa

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).

Protocol for the evaluation of the population-level impact of Zimbabwe's prevention of mother-to-child HIV transmission program option B+: a community based serial cross-sectional study

Background

WHO recommends that HIV infected women receive antiretroviral therapy (ART) minimally during pregnancy and breastfeeding (“Option B”), or ideally throughout their lives regardless of clinical stage (“Option B+”) (Coovadia et al., Lancet 379:221–228, 2012). Although these recommendations were based on clinical trials demonstrating the efficacy of ART during pregnancy and breastfeeding, the population-level effectiveness of Option B+ is unknown, as are retention on ART beyond the immediate post-partum period, and the relative impact and cost-effectiveness of Option B+ compared to Option A (Centers for Disease Control and Prevention, Morb Mortal Wkly Rep 62:148–151, 2013; Ahmed et al., Curr Opin HIV AIDS 8:473–488, 2013). To address these issues, we conducted an impact evaluation of Zimbabwe’s prevention of mother to child transmission programme conducted between 2011 and 2018 using serial, community-based cross-sectional serosurveys, which spanned changes in WHO recommendations. Here we describe the rationale for the design and analysis.

Methods/design

Our method is to survey mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. We collect questionnaires, blood samples from mothers and babies for HIV antibody and viral load testing, and verbal autopsies for deceased mothers/babies. Using this approach, we collected data from two previous time points: 2012 (pre-Option A standard of care), 2014 (post-Option A / pre-Option B+) and will collect a third round of data in 2017–18 (post Option B+ implementation) to monitor population-level trends in mother-to-child transmission of HIV (MTCT) and HIV-free infant survival. In addition, we will collect detailed information on facility level factors that may influence service delivery and costs.

Discussion

Although the efficacy of antiretroviral therapy (ART) during pregnancy and breastfeeding for prevention of mother-to-child transmission of HIV (PMTCT) has been well-documented in randomized trials, little evidence exists on the population-level impact and cost-effectiveness of Option B+ or the influence of the facility on implementation (Siegfried et al., Cochrane Libr 7:CD003510, 2017). This study will provide essential data on these gaps and will provide estimates on retention in care among Option B+ clients after the breastfeeding period.

Measuring productivity and its relationship to community health worker performance in Uganda: a cross-sectional study

BACKGROUND

To explore the nature of the relationship between and factors associated with productivity and performance among the community health volunteer (CHV) cadre (Village Health Teams, VHT) in Busia District, Eastern Uganda. The study was carried out to contribute to the global evidence on strategies to improve CHV productivity and performance.

METHODS

This cross-sectional study was conducted with 140 VHT members as subjects and respondents. Data were collected between March and May 2013 on the performance and productivity of VHT members related to village visits and activities for saving maternal and child lives, as well as on independent factors that may be associated with these measures. Data were collected through direct observation of VHT activities, structured interviews with VHTs, and review of available records. The correlation between performance and productivity scores was estimated, and LASSO regression analyses were conducted to identify factors associated with these two scores independently.

RESULTS

VHTs demonstrated wide variation in productivity measures, conducting a median of 13.2 service units in a three-month span (range: 2.0-114.9). Performance of the studied VHTs was generally high, with a median performance score (out of 100) of 96.4 (range: 50.9-100.0). We observed a weak correlation coefficient of 0.05 (p = 0.57) between productivity and performance scores. Older VHT age (≥50 years old, reference: <50 years old) (11.14, 95% CI: 3.26-19.01) and knowledge of danger signs (in units of ten-percentage points, 1.92, 95% CI: 0.01-3.83) were positively associated with productivity scores. Job satisfaction (1.46, 95% CI: 0.13-2.80) and knowledge of danger signs (in units of ten-percentage points, 1.02, 95% CI: 0.05-1.98) were positively associated with performance scores.

CONCLUSIONS

Older VHT age and knowledge of danger signs were positively associated with productivity, and job satisfaction and knowledge of danger signs were positively associated with performance. No correlation was observed between productivity and performance scores. This lack of correlation suggests that interventions to improve CHV effectiveness may affect the two dimensions of effectiveness differently. We recommend that productivity and performance both be monitored to evaluate the overall impact of interventions to increase CHV effectiveness.

ASSOCIATION BETWEEN HIV AWARENESS FACTORS, HEALTH FACILITY CHARACTERISTICS AND RISKY SEXUAL BEHAVIOUR AMONG YOUNG WOMEN IN ZOMBA DISTRICT, MALAWI

The objective of this study was to examine the association between multilevel factors related to HIV awareness and risky sexual behaviour among young women in Zomba district, Malawi. Secondary analyses of the Schooling, Income, and Health Risk (SIHR) study were undertaken. Four outcomes related to risky sexual behaviour were examined among young women: if participants had ever had sex, consistent condom use and two scores measuring risk related to partner history and age during sexual activity. Independent variables included individual-level factors such as education and rural/urban residence, as well as higher-level factors such as household's highest level of education and health facility characteristics. Regression models with cluster-robust standard errors and multilevel regression models were used to estimate associations; analyses were stratified into two strata by school enrolment status, i.e. whether the women were in school (N=1407) or had dropped out of school (N=407) at baseline of the SIHR study. For both strata, increasing age and residing within 16 km of an urban centre ('near rural' residence) increased the odds of ever having sex; lower educational achievement was associated with lower age during sexual activity. A history of pregnancy was associated with lower odds of condom use and riskier partner history. For women in school at baseline, lower household education was associated with higher odds of ever having sex (OR=1.48; 95% CI: 1.06, 2.07); near-rural and far-rural (≤16 km and &gt;16km from urban centre, respectively) residence were associated with decreased odds of condom use (OR=0.47; 95% CI: 0.28, 0.78; and OR=0.27; 95% CI: 0.11, 0.65, respectively). For those not in school at baseline, lower household education was associated with lower age during sexual activity (β=0.31, 95% CI: 0.05, 0.58). Also for women not in school, the use of private or non-governmental health facilities was associated with decreased odds of condom use (OR=0.51, 95% CI: 0.39, 0.67) and higher age during sexual activity (β=-0.30, 95% CI: -0.52, -0.09). While individual factors were associated with risky sexual behaviour in both strata, contextual factors differed.

Can mother-to-child transmission of HIV be eliminated without addressing the issue of stigma? Modeling the case for a setting in South Africa

BACKGROUND

Stigma and discrimination ontinue to undermine the effectiveness of the HIV response. Despite a growing body of evidence of the negative relationship between stigma and HIV outcomes, there is a paucity of data available on the prevalence of stigma and its impact. We present a probabilistic cascade model to estimate the magnitude of impact stigma has on mother-to-child-transmission (MTCT).

METHODS

The model was parameterized using 2010 data from Johannesburg, South Africa, from which loss-to-care at each stage of the antenatal cascade were available. Three scenarios were compared to assess the individual contributions of stigma, non-stigma related barriers, and drug ineffectiveness on the overall number of infant infections. Uncertainty analysis was used to estimate plausible ranges. The model follows the guidelines in place in 2010 when the data were extracted (WHO Option A), and compares this with model results had Option B+ been implemented at the time.

RESULTS

The model estimated under Option A, 35% of infant infections being attributed to stigma. This compares to 51% of total infections had Option B+ been implemented in 2010. Under Option B+, the model estimated fewer infections than Option A, due to the availability of more effective drugs. Only 8% (Option A) and 9% (Option B+) of infant infections were attributed to drug ineffectiveness, with the trade-off in the proportion of infections being between stigma and non-stigma-related barriers.

CONCLUSIONS

The model demonstrates that while the effect of stigma on retention of women at any given stage along the cascade can be relatively small, the cumulative effect can be large. Reducing stigma may be critical in reaching MTCT elimination targets, because as countries improve supply-side factors, the relative impact of stigma becomes greater. The cumulative nature of the PMTCT cascade results in stigma having a large effect, this feature may be harnessed for efficiency in investment by prioritizing interventions that can affect multiple stages of the cascade simultaneously.

Stepped-Wedge Cluster Randomized Controlled Trial to Promote Option B+ Retention in Central Mozambique

BACKGROUND

This randomized trial studied performance of Option B+ in Mozambique and evaluated an enhanced retention package in public clinics.

SETTING

The study was conducted at 6 clinics in Manica and Sofala Provinces in central Mozambique.

METHODS

Seven hundred sixty-one pregnant women tested HIV+, immediately initiated antiretroviral (ARV) therapy, and were followed to track retention at 6 clinics from May 2014 to May 2015. Clinics were randomly allocated within a stepped-wedge fashion to intervention and control periods. The intervention included (1) workflow modifications and (2) active patient tracking. Retention was defined as percentage of patients returning for 30-, 60-, and 90-day medication refills within 25-35 days of previous refills.

RESULTS

During control periods, 52.3% of women returned for 30-day refills vs. 70.8% in intervention periods [odds ratio (OR): 1.80; 95% confidence interval (CI): 1.05 to 3.08]. At 60 days, 46.1% control vs. 57.9% intervention were retained (OR: 1.82; CI: 1.06 to 3.11), and at 90 days, 38.3% control vs. 41.0% intervention (OR: 1.04; CI: 0.60 to 1.82). In prespecified subanalyses, birth before pickups was strongly associated with failure-women giving birth before ARV pickup were 33.3 times (CI: 4.4 to 250.3), 7.5 times (CI: 3.6 to 15.9), and 3.7 times (CI: 2.2 to 6.0) as likely to not return for ARV pickups at 30, 60, and 90 days, respectively.

CONCLUSIONS

The intervention was effective at 30 and 60 days, but not at 90 days. Combined 90-day retention (40%) and adherence (22.5%) were low. Efforts to improve retention are particularly important for women giving birth before ARV refills.

Option B+ in Mozambique: Formative Research Findings for the Design of a Facility-Level Clustered Randomized Controlled Trial to Improve ART Retention in Antenatal Care

INTRODUCTION

With the rollout of "Option B+" in Mozambique in 2013, initial data indicated major challenges to early retention in antiretroviral therapy (ART) among HIV-positive pregnant women. We sought to develop and test a pilot intervention in 6 large public clinics in central Mozambique to improve retention of mothers starting ART in antenatal care. The results from the formative research from this study described here were used to design the intervention.

METHODS

The research was initiated in early 2013 and completed in early 2014 in each of the 6 study clinics and consisted of (1) patient flow mapping and measurement of retention through collection of health systems data from antenatal care registries, pharmacy registries, ART clinic databases, (2) workforce assessment and measurement of patient waiting times, and (3) patient and worker individual interviews and focus groups.

RESULTS

Coverage of HIV testing and ART initiation were over 90% at all sites, but retention at 30-, 60-, and 90-day pharmacy refill visits was very low ranging from only 5% at 1 site to 30% returning at 90 days. These data revealed major systemic bottlenecks that contributed to poor adherence and retention in the first month after ART initiation. Long wait times, short consultations, and poor counseling were identified as barriers.

CONCLUSIONS

Based on these findings, we designed an intervention with these components: (1) workflow modification to redefine nurse tasks, shift tasks to community health workers, and enhance patient tracking and (2) an adherence and retention package to systematize active patient follow-up, ensure home visits by community health workers, use text messaging, and intensify counseling by health staff. This intervention is currently under evaluation using a stepped wedge design.

Lessons Learned From Option B+ in the Evolution Toward "Test and Start" From Malawi, Cameroon, and the United Republic of Tanzania

The acceleration of prevention of mother-to-child transmission (PMTCT) activities, coupled with the rollout of 2010 World Health Organization (WHO) guidelines, led to important discussions and innovations at global and country levels. One paradigm-shifting innovation was Option B+ in Malawi. It was later included in WHO guidelines and eventually adopted by all 22 Global Plan priority countries. This article presents Malawi's experience with designing and implementing Option B+ and provides complementary narratives from Cameroon and Tanzania. Malawi's HIV program started in 2002, but by 2009, the PMTCT program was lagging far behind the antiretroviral therapy (ART) program because of numerous health system challenges. When WHO recommended Option A and Option B for PMTCT in 2010, it was clear that Malawi's HIV program would not be able to successfully implement either option without increasing existing barriers to PMTCT services and potentially decreasing women's access to care. Subsequent stakeholder discussions led to the development of Option B+. Operationalizing Option B+ required several critical considerations, including the complete integration of ART and PMTCT programs, systematic reduction of barriers to facilitate doubling the number of ART sites in less than a year, building consensus with stakeholders, and securing additional resources for the new program. During the planning and implementation process, several lessons were learned which are considerations for countries transitioning to "treat-all": Comprehensive change requires effective government leadership and coordination; national clinical guidelines must accommodate health system limitations; ART services and commodities should be decentralized within facilities; the general public should be well informed about major changes in the national HIV program; and patients should be educated on clinic processes to improve program monitoring.

Health facility service availability and readiness for intrapartum and immediate postpartum care in Malawi: A cross-sectional survey

This analysis seeks to identify strengths and gaps in the existing facility capacity for intrapartum and immediate postpartum fetal and neonatal care, using data collected as a part of Malawi’s Helping Babies Breath program evaluation. From August to September 2012, the Maternal and Child Health Integrated Program (MCHIP) conducted a cross-sectional survey in 84 Malawian health facilities to capture current health facility service availability and readiness and health worker capacity and practice pertaining to labor, delivery, and immediate postpartum care. The survey collected data on availability of equipment, supplies, and medications, and health worker knowledge and performance scores on intrapartum care simulation and actual management of real clients at a subset of facilities. We ran linear regression models to identify predictors of high simulation performance of routine delivery care and management of asphyxiated newborns across all facilities surveyed. Key supplies for infection prevention and thermal care of the newborn were found to be missing in many of the surveyed facilities. At the health center level, 75% had no clinician trained in basic emergency obstetric care or newborn care and 39% had no midwife trained in the same. We observed that there were no proportional increases in available transport and staff at a facility as catchment population increased. In simulations of management of newborns with breathing problems, health workers were able to complete a median of 10 out of 16 tasks for a full-term birth case scenario and 20 out of 30 tasks for a preterm birth case scenario. Health workers who had more years of experience appeared to perform worse. Our study provides a benchmark and highlights gaps for future evaluations and studies as Malawi continues to make strides in improving facility-based care. Further progress in reducing the burden of neonatal and fetal death in Malawi will be partly predicated on guaranteeing properly equipped and staffed facilities in addition to ensuring the presence of skilled health workers.

Timely antiretroviral prophylaxis during pregnancy effectively reduces HIV mother-to-child transmission in eight counties in China: a prospective study during 2004-2011

This study investigates the improvement of the prevention of mother-to-child transmission (PMTCT) of Human Immunodeficiency Virus (HIV) in China during 2004-2011. A clinic-based prospective study was conducted among HIV-positive pregnant women and their children in eight counties across China. Associated factors of mother-to-child transmission were analyzed using regression analysis. A total of 1,387 HIV+ pregnant women and 1,377 HIV-exposed infants were enrolled. The proportion of pregnant women who received HIV testing increased significantly from 45.1% to 98.9% during 2004-2011. Among whom, the proportion that received antiretroviral (ARV) prophylaxis increased from 61% to 96%, and the corresponding coverage in children increased from 85% to 97% during the same period. In contrast, single-dose nevirapine treatment during delivery declined substantially from 97.9% to 12.7%. Vertical transmission of HIV declined from 11.1% (95% confidence interval [CI]: 5.7-23.3%) in 2004 to 1.2% (95% CI: 0.1-5.8%) in 2011. Women who had a vaginal delivery (compared to emergency caesarian section (odds ratio [OR] = 0.46; 0.23-0.96)) and mothers on multi-ARVs (OR = 0.11; 0.04-0.29) were less likely to transmit HIV to their newborns. Increasing HIV screening enabled timely HIV care and prophylaxis to reduce vertical transmission of HIV. Early and consistent treatment with multi-ARVs during pregnancy is vital for PMTCT.

Predictors of Infant Age at Enrollment in Early Infant Diagnosis Services in Kenya

Despite the importance of early detection to signal lifesaving treatment initiation for HIV+ infants, early infant diagnosis (EID) services have received considerably less attention than other aspects of prevention of mother to child transmission care. This study draws on baseline data from an on-going cluster randomized study of an intervention to improve EID services at six government hospitals across Kenya. Two logistic regressions examined potential predictors of “on time” (infant ≤6 weeks of age) vs. “late” (≥7 weeks) and “on time” versus “very late” (≥12 weeks) EID engagement among 756 mother-infant pairs. A quarter of the infants failed to get “on time” testing. Predictors of “on time” testing included being informed about EID by providers when pregnant, perceiving less HIV stigma, and mother’s level of education. Predictors of “very late” testing (≥12 weeks of age) included not being informed about EID by providers when pregnant and living farther from services. Findings highlight the importance of ensuring that health care providers actively and repeatedly inform HIV+ mothers of the availability of EID services, reduce stigma by frequently communicating judgment free support, and assisting mothers in early planning for accessing EID services. Extra care should be focused on engaging mothers with less formal education who are at increased risk for seeking “late” EID testing. This study offers clear targets for improving services so that all HIV-exposed infants can be properly engaged in EID services, thus increasing the potential for the best possible outcomes for this vulnerable population.

Active tracking of rejected dried blood samples in a large program in Nigeria

AIM: To study the impact of rejection at different levels of health care by retrospectively reviewing records of dried blood spot samples received at the molecular laboratory for human immunodeficiency virus (HIV) early infant diagnosis (EID) between January 2008 and December 2012.

METHODS: The specimen rejection rate, reasons for rejection and the impact of rejection at different levels of health care was examined. The extracted data were cleaned and checked for consistency and then de-duplicated using the unique patient and clinic identifiers. The cleaned data were ciphered and exported to SPSS version 19 (SPSS 2010 IBM Corp, New York, United States) for statistical analyses.

RESULTS: Sample rejection rate of 2.4% (n = 786/32552) and repeat rate of 8.8% (n = 69/786) were established. The mean age of infants presenting for first HIV molecular test among accepted valid samples was 17.83 wk (95%CI: 17.65-18.01) vs 20.30 wk (95%CI: 16.53-24.06) for repeated samples. HIV infection rate was 9.8% vs 15.9% for accepted and repeated samples. Compared to tertiary healthcare clinics, secondary and primary clinics had two-fold and three-fold higher likelihood of sample rejection, respectively (P < 0.05). We observed a significant increase in sample rejection rate with increasing number of EID clinics (r = 0.893, P = 0.041). The major reasons for rejection were improper sample collection (26.3%), improper labeling (16.4%) and insufficient blood (14.8%).

CONCLUSION: Programs should monitor pre-analytical variables and incorporate continuous quality improvement interventions to reduce errors associated with sample rejection and improve patient retention.

Towards elimination of mother-to-child transmission of HIV in Ghana: an analysis of national programme data

BACKGROUND

Despite global scale up of interventions for Preventing Mother to child HIV Transmissions (PMTCT), there still remain high pediatric HIV infections, which result from unequal access in resource-constrained settings. Sub-Saharan Africa alone contributes more than 90 % of global Mother-to-Child Transmission (MTCT) burden. As part of efforts to address this, African countries (including Ghana) disproportionately contributing to MTCT burden were earmarked in 2009 for rapid PMTCT interventions scale-up within their primary care system for maternal and child health. In this study, we reviewed records in Ghana, on ANC registrants eligible for PMTCT services to describe regional disparities and national trends in key PMTCT indicators. We also assessed distribution of missed opportunities for testing pregnant women and treating those who are HIV positive across the country. Implications for scaling up HIV-related maternal and child health services to ensure equitable access and eliminate mother-to-child transmissions by 2015 are also discussed.

METHODS

Data for this review is National AIDS/STI Control Programme (NACP) regional disaggregated records on registered antenatal clinic (ANC) attendees across the country, who are also eligible to receive PMTCT services. These records cover a period of 3 years (2011-2013). Number of ANC registrants, utilization of HIV Testing and Counseling among ANC registrants, number of HIV positive pregnant women, and number of HIV positive pregnant women initiated on ARVs were extracted. Trends were examined by comparing these indicators over time (2011-2013) and across the ten administrative regions. Descriptive statistics were conducted on the dataset and presented in simple frequencies, proportions and percentages. These are used to determine gaps in utilization of PMTCT services. All analyses were conducted using Microsoft Excel 2010 version.

RESULTS

Although there was a decline in HIV prevalence among pregnant women, untested ANC registrants increased from 17 % in 2011 to 25 % in 2013. There were varying levels of missed opportunities for testing across the ten regions, which led to a total of 487,725 untested ANC clients during the period under review. In 2013, Greater Accra (31 %), Northern (27 %) and Volta (48 %) regions recorded high percentages of untested ANC clients. Overall, HIV positive pregnant women initiated onto ARVs remarkably increased from 57% (2011) to 82 % (2013), yet about a third (33 %) of them in the Volta and Northern regions did not receive ARVs in 2013.

CONCLUSIONS

Missed opportunities to test pregnant women for HIV and also initiate those who are positive on ARVs across all the regions pose challenges to the quest to eliminate mother-to-child transmission of HIV in Ghana. For some regions these missed opportunities mimic previously observed gaps in continuous use of primary care for maternal and child health in those areas. Increased national and regional efforts aimed at improving maternal and child healthcare delivery, as well as HIV-related care, is paramount for ensuring equitable access across the country.

Perspectives on safer conception practices and preconception counseling among women living with HIV

Pregnancies are frequently unplanned, and higher rates of unplanned pregnancies occur among HIV-infected women. Reviewers examined reproductive decision making, conception practices, and patient-provider communication among women living with HIV. Qualitative interviews were conducted with 19 HIV-infected sexually active women aged 18-45 in southern Florida, USA. Using thematic analysis, we found decisions to conceive were influenced by women and partners; knowledge and use of safer conception practices were low. Discussion and support from partners, family, and providers was limited and diminished by stigma and nondisclosure. Preconception counseling discussions in HIV care should be comprehensive and initiated frequently by all health care providers.

Tracing defaulters in HIV prevention of mother-to-child transmission programmes through community health workers: results from a rural setting in Zimbabwe

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.

Supporting Option B+ scale up and strengthening the prevention of mother-to-child transmission cascade in central Malawi: results from a serial cross-sectional study

BACKGROUND

We established Safeguard the Family (STF) to support Ministry of Health (MoH) scale-up of universal antiretroviral therapy (ART) for HIV-infected pregnant and breastfeeding women (Option B+) and to strengthen the prevention of mother-to-child transmission (PMTCT) cascade from HIV testing and counseling (HTC) through maternal ART provision and post-delivery early infant HIV diagnosis (EID). To these ends, we implemented the following interventions in 5 districts: 1) health worker training and mentorship; 2) couples' HTC and male partner involvement; 3) women's psychosocial support groups; and 4) health and laboratory system strengthening for EID.

METHODS

We conducted a serial cross-sectional study using facility-level quarterly (Q) program data and individual-level infant HIV-1 DNA PCR data to evaluate STF performance on PMTCT indicators for project years (Y) 1 (April-December 2011) through 3 (January-December 2013), and compared these results to national averages.

RESULTS

Facility-level uptake of HTC, ART, infant nevirapine prophylaxis, and infant DNA PCR testing increased significantly from quarterly baselines of 66 % (n/N = 32,433/48,804), 23 % (n/N = 442/1,958), 1 % (n/N = 10/1,958), and 52 % (n/N = 1,385/2,644) to 87 % (n/N = 39,458/45,324), 96 % (n/N = 2,046/2,121), 100 % (n/N = 2,121/2,121), and 62 % (n/N = 1,462/2,340), respectively, by project end (all p < 0.001). Quarterly HTC, ART, and infant nevirapine prophylaxis uptake outperformed national averages over years 2-3. While transitioning EID laboratory services to MoH, STF provided first-time HIV-1 DNA PCR testing for 2,226 of 11,261 HIV-exposed infants (20 %) tested in the MoH EID program in STF districts from program inception (Y2) through Y3. Of these, 78 (3.5 %) tested HIV-positive. Among infants with complete documentation (n = 608), median age at first testing decreased from 112 days (interquartile range, IQR: 57-198) in Y2 to 76 days (IQR: 46-152) in Y3 (p < 0.001). During Y3 (only year with national data for comparison), non-significantly fewer exposed infants tested HIV-positive (3.6 %) at first testing in STF districts than nationally (4.1 %) (p = 0.4).

CONCLUSIONS

STF interventions, integrated within the MoH Option B+ program, achieved favorable HTC, maternal ART, infant prophylaxis, and EID services uptake, and a low proportion of infants found HIV-infected at first DNA PCR testing. Continued investments are needed to strengthen the PMTCT cascade, particularly around EID.

Evaluating the Impact of Zimbabwe's Prevention of Mother-to-Child HIV Transmission Program: Population-Level Estimates of HIV-Free Infant Survival Pre-Option A

Objective

We estimated HIV-free infant survival and mother-to-child HIV transmission (MTCT) rates in Zimbabwe, some of the first community-based estimates from a UNAIDS priority country.

Methods

In 2012 we surveyed mother-infant pairs residing in the catchment areas of 157 health facilities randomly selected from 5 of 10 provinces in Zimbabwe. Enrolled infants were born 9–18 months before the survey. We collected questionnaires, blood samples for HIV testing, and verbal autopsies for deceased mothers/infants. Estimates were assessed among i) all HIV-exposed infants, as part of an impact evaluation of Option A of the 2010 WHO guidelines (rolled out in Zimbabwe in 2011), and ii) the subgroup of infants unexposed to Option A. We compared province-level MTCT rates measured among women in the community with MTCT rates measured using program monitoring data from facilities serving those communities.

Findings

Among 8568 women with known HIV serostatus, 1107 (12.9%) were HIV-infected. Among all HIV-exposed infants, HIV-free infant survival was 90.9% (95% confidence interval (CI): 88.7–92.7) and MTCT was 8.8% (95% CI: 6.9–11.1). Sixty-six percent of HIV-exposed infants were still breastfeeding. Among the 762 infants born before Option A was implemented, 90.5% (95% CI: 88.1–92.5) were alive and HIV-uninfected at 9–18 months of age, and 9.1% (95%CI: 7.1–11.7) were HIV-infected. In four provinces, the community-based MTCT rate was higher than the facility-based MTCT rate. In Harare, the community and facility-based rates were 6.0% and 9.1%, respectively.

Conclusion

By 2012 Zimbabwe had made substantial progress towards the elimination of MTCT. Our HIV-free infant survival and MTCT estimates capture HIV transmissions during pregnancy, delivery and breastfeeding regardless of whether or not mothers accessed health services. These estimates also provide a baseline against which to measure the impact of Option A guidelines (and subsequently Option B+).

The role of maternal, health system, and psychosocial factors in prevention of mother-to-child transmission failure in the era of programmatic scale up in western Kenya: a case control study

The aim of this study was to identify factors associated with prevention of mother-to-child transmission (PMTCT) in an area of Kenya with widely accessible free PMTCT services. A matched case-control study was conducted at 31 public facilities in western Kenya. HIV-infected mothers with infants aged 6 weeks to 6 months were interviewed and medical charts were reviewed. Cases were mothers of infants with a definitive diagnosis of HIV. Controls were mothers of infants testing HIV negative. Cases and controls were matched in a 1:3 ratio on socio-demographic factors. Fifty cases and 135 controls were enrolled. Conditional (matched) logistic regression analysis was conducted. Odds of being a case were higher for women who first learned their HIV status during pregnancy [OR:2.85, 95%CI:1.41-5.78], did not adhere to antiretroviral therapy (ART) [OR:3.35, 95%CI:1.48-7.58], or had a home delivery [OR:2.42, 95%CI:1.01-5.80]. Based on medical record review, cases had higher odds of their provider not following guidelines for prescription of ART for mothers [OR:8.61, 95%CI:2.83-26.15] and infants [OR:9.72, 95%CI:2.75-34.37]. Stigma from the community [OR:0.37, 95% CI:0.14-1.02] or facility [OR:0.38, 95%CI:0.04-3.41], did not increase the odds of MTCT. Poor adherence to PMTCT guidelines and recommendations by both infected women and health care providers hamper efforts to attain elimination of MTCT.

Adherence to HIV care after pregnancy among women in sub-Saharan Africa: falling off the cliff of the treatment cascade

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.

Barriers to successful implementation of prevention-of-mother-to-child-transmission (PMTCT) of HIV programmes in Malawi and Nigeria: a critical literature review study

Mother-to-child-transmission (MTCT) of HIV still remains a significant route of new HIV infection in children in Malawi and Nigeria, despite the introduction of Prevention-of-Mother-to-Child-Transmission (PMTCT) of HIV programmes in both countries. A critical literature review, based on the findings from 12 primary research articles, explores the reasons for the inadequacy and failure of PMTCT. Findings show socioeconomic and sociocultural factors as the biggest barriers to the success of PMTCT programmes. Other factors include: limited male involvement, the organization of PMTCT and health workers’ inefficiency. In conclusion, PMTCT programmes will remain inefficient unless these factors are addressed. There is an urgent need to strengthen PMTCT programmes by stakeholders through a collaborative strategic effort to ensure high PMTCT programme uptake in Malawi and Nigeria, in order to eliminate HIV/AIDS in children.

Partner testing, linkage to care, and HIV-free survival in a program to prevent parent-to-child transmission of HIV in the Highlands of Papua New Guinea

Background

To eliminate new pediatric HIV infections, interventions that facilitate adherence, including those that minimize stigma, enhance social support, and mitigate the influence of poverty, will likely be required in addition to combination antiretroviral therapy (ART). We examined the relationship between partner testing and infant outcome in a prevention of parent-to-child transmission of HIV program, which included a family-centered case management approach and a supportive environment for partner disclosure and testing.

Design

We analyzed routinely collected data for women and infants who enrolled in the parent-to-child transmission of HIV program at Goroka Family Clinic, Eastern Highlands Provincial Hospital, Papua New Guinea, from 2007 through 2011.

Results

Two hundred and sixty five women were included for analysis. Of these, 226 (85%) had a partner, 127 (56%) of whom had a documented HIV test. Of the 102 HIV-infected partners, 81 (79%) had been linked to care. In adjusted analyses, we found a significantly higher risk of infant death, infant HIV infection, or loss to follow-up among mother–infant pairs in which the mother reported having no partner or a partner who was not tested or had an unknown testing status. In a second multivariable analysis, infants born to women with more time on ART or who enrolled in the program in later years experienced greater HIV-free survival.

Conclusions

In a program with a patient-oriented and family-centered approach to prevent vertical HIV transmission, the majority of women's partners had a documented HIV test and, if positive, linkage to care. Having a tested partner was associated with program retention and HIV-free survival for infants. Programs aiming to facilitate diagnosis disclosure, partner testing, and linkage to care may contribute importantly to the elimination of pediatric HIV.

The role of family planning in elimination of new pediatric HIV infection

PURPOSE OF REVIEW

We reviewed recent literature on the role of family planning in eliminating new pediatric HIV infections.

RECENT FINDINGS

Global commitments to eliminate new pediatric HIV infections recognize that preventing unintended pregnancies among women with HIV is essential to achieving this goal. However, substantial shortcomings exist in translating this policy support into widespread practice. Programs to prevent mother-to-child transmission of HIV continue to be implemented and evaluated as a narrow set of interventions that typically begins in antenatal care, after a woman is already pregnant. In addition, data suggest that women living with HIV experience high rates of unmet need for family planning and unintended pregnancies. Evidence is growing that integrating family planning and HIV services is an effective strategy for increasing access to contraception among women with HIV who do not wish to become pregnant. A number of health system obstacles must be resolved to achieve effective, sustained delivery of integrated services at scale.

SUMMARY

Prevention of unintended pregnancies among women with HIV must be elevated as a programmatic priority. By strengthening family planning programs for all women, and better integrating family planning and HIV services, progress toward ending new pediatric HIV infections will be accelerated.

A qualitative analysis of the barriers and facilitators to receiving care in a prevention of mother-to-child program in Nkhoma, Malawi

Prior to 2011, uptake of PMTCT in Malawi remained low despite increased access to antiretrovirals. We sought to understand barriers to PMTCT in rural Malawi. Twenty-two HIV-infected pregnant and postpartum women in PMTCT programs were interviewed in Nkhoma, Malawi, between April-May 2010. All women were staged by WHO criteria or CD4 count as ineligible for three-drug treatment by Malawi's HIV Guidelines at the time. The median age was 26 years (range 22-39) and 77% were married. Barriers to accessing PMTCT care included transportation to clinic, stigma in the community leading to avoidance of HIV disclosure, food insecurity, and providers' attitudes towards HIV-infected pregnant women. Given Malawi's transition to Option B+ for PMTCT in which women are initiated on antiretroviral therapy (ART) during pregnancy and continued for life, strategies to improve access and retention will need to address barriers and incorporate facilitators that motivate and retain women in HIV care.

Women's choices regarding HIV testing, disclosure and partner involvement in infant feeding and care in a rural district of Malawi with high HIV prevalence

The influence of HIV-related stigma on women's choices with regard to HIV testing, disclosure and partner involvement in infant feeding and care is not well understood in rural Malawi but may influence the risk of vertical HIV transmission and infant health. In a study of HIV-infected and -uninfected women in 20 rural locations in Zomba District, Malawi, mothers were questioned at 18-20 months post-partum about these issues. Ten per cent of women claimed unknown HIV status in labour so HIV testing should be routinely offered in Labour & Delivery wards. HIV-infected women were somewhat less likely to disclose to their partners than HIV-uninfected women (89 and 97%, respectively; p = 0.007) or to be cohabiting with partners during pregnancy (74 and 86%, respectively; p = 0.03). Partners of women were less inclined to disclose their HIV testing or HIV status (49 and 66% of partners of HIV-infected and -uninfected women, respectively). Greater partner testing and disclosure may improve prevention of mother to child transmission of HIV (PMTCT) in this population. A majority of women were inclined to make feeding decisions on their own, whereas most felt that other health-related decisions should also involve the father. Most mothers believe that exclusive breast feeding (EBF) is the best infant feeding method (for the first six months) but it was actually practiced by a minority of women (20% of HIV-infected and 5% of HIV-uninfected mothers; p = 0.01). EBF needs systematic support in order to be practised.

Translation of biomedical prevention strategies for HIV: prospects and pitfalls

Early achievements in biomedical approaches for HIV prevention included physical barriers (condoms), clean injection equipment (both for medical use and for injection drug users), blood and blood product safety, and prevention of mother-to-child transmission. In recent years, antiretroviral drugs to reduce the risk of transmission (when the infected person takes the medicines; treatment as prevention) or reduce the risk of acquisition (when the seronegative person takes them; preexposure prophylaxis) have proven to be efficacious. Circumcision of men has also been a major tool relevant for higher prevalence regions such as sub-Saharan Africa. Well-established prevention strategies in the control of sexually transmitted diseases and tuberculosis are highly relevant for HIV (ie, screening, linkage to care, early treatment, and contact tracing). Unfortunately, only slow progress is being made in some available HIV-prevention strategies such as family planning for HIV-infected women who do not want more children and prevention of mother-to-child HIV transmission. Current studies seek to integrate strategies into approaches that combine biomedical, behavioral, and structural methods to achieve prevention synergies. This review identifies the major biomedical approaches demonstrated to be efficacious that are now available. We also highlight the need for behavioral risk reduction and adherence as essential components of any biomedical approach.

Infant feeding in the context of HIV: a qualitative study of health care workers' knowledge of recommended infant feeding options in Papua New Guinea

Background

Interventions to prevent mother to child transmission of human immunodeficiency virus (HIV) during childbirth and breastfeeding can reduce HIV infections in infants to less than 5% in low and middle income countries. The World Health Organization (WHO) recommends all mothers, regardless of their HIV status, practice exclusive breastfeeding for the first six months of an infant’s life. In line with these recommendations and to protect, promote and support breastfeeding, in 2009 the PNG National Department of Health revised their National HIV infant feeding guidelines, reinforcing the WHO recommendation of exclusive breastfeeding for the first six months followed by the introduction of other food and fluids, while continuing breastfeeding.

The overall aim of this paper is to explore health care workers’ knowledge regarding infant feeding options in PNG, specifically as they relate to HIV exposed infants.

Methods

As part of a study investigating women’s and men’s experiences of prevention of mother to child transmission (PMTCT) services in two sites in PNG, 28 key informant interviews were undertaken. This paper addresses one theme that emerged from thematic data analysis: Health care workers’ knowledge regarding infant feeding options, specifically how this knowledge reflects the Papua New Guinea National HIV Care and Treatment Guidelines on HIV and infant feeding (2009).

Results

Most informants mentioned exclusive breastfeeding, the majority of whom reflected the most up-to-date National Guidelines of exclusive breastfeeding for six months. The importance of breastfeeding continuing beyond this time, along with the introduction of food and fluids was less well understood. The most senior people involved in PMTCT were the informants who most accurately reflected the national guidelines of continuing breastfeeding after six months.

Conclusion

Providing advice on optimal infant feeding in resource poor settings is problematic, especially in relation to HIV transmission. Findings from our study reflect those found elsewhere in identifying that key health care workers are not aware of up-to-date information relating to infant feeding, especially within the context of HIV. Greater emphasis needs to be placed on ensuring the most recent feeding guidelines are disseminated and implemented in clinical practice in PNG.

Mortality and health outcomes of HIV-exposed and unexposed children in a PMTCT cohort in Malawi

BACKGROUND

Mortality and morbidity among HIV-exposed children are thought to be high in Malawi. We sought to determine mortality and health outcomes of HIV-exposed and unexposed infants within a PMTCT program.

METHOD

Data were collected as part of a retrospective cohort study in Zomba District, Malawi. HIV-infected mothers were identified via antenatal, delivery and postpartum records with a delivery date 18-20 months prior; the next registered HIV-uninfected mother was identified as a control. By interview and health record review, data on socio-demographic characteristics, service uptake, and health outcomes were collected. HIV-testing was offered to all exposed children.

RESULTS

173 HIV-infected and 214 uninfected mothers were included. 4 stillbirths (1.0%) occurred; among the 383 livebirths, 41 (10.7%) children died by 20 months (32 (18.7%) HIV-exposed and 9 unexposed children (4.3%; p<0.0001)). Risk factors for child death included: HIV-exposure [adjOR2.9(95%CI 1.1-7.2)], low birthweight [adjOR2.5(1.0-6.3)], previous child death (adjOR25.1(6.5-97.5)] and maternal death [adjOR5.3(11.4-20.5)]. At 20 months, HIV-infected children had significantly poorer health outcomes than HIV-unexposed children and HIV-exposed but uninfected children (HIV-EU), including: hospital admissions, delayed development, undernutrition and restrictions in function (Lansky scale); no significant differences were seen between HIV-EU and HIV-unexposed children. Overall, no difference was seen at 20 months among HIV-infected, HIV-EU and HIV-unexposed groups in Z-scores (%<-2.0) for weight, height and BMI. Risk factors for poor functional health status at 20 months included: HIV-infection [adjOR8.9(2.4-32.6)], maternal illness [adjOR2.8(1.5-5.0)] and low birthweight [adjOR2.0(1.0-4.1)].

CONCLUSION

Child mortality remains high within this context and could be reduced through more effective PMTCT including prioritizing the treatment of maternal HIV infection to address the effect of maternal health and survival on infant health and survival. HIV-infected children demonstrated developmental delays, functional health and nutritional deficits that underscore the need for increased uptake of early infant diagnosis and institution of ART for all infected infants.

Superior uptake and outcomes of early infant diagnosis of HIV services at an immunization clinic versus an "under-five" general pediatric clinic in Malawi

OBJECTIVE

Although the Malawian government recommends HIV-exposed infants receive early infant diagnosis (EID) of HIV at "under-five" pediatric clinics (U5Cs), most never enroll. Therefore, we evaluated the integration of EID testing into an immunization clinic (IC) compared with the current standard of EID testing at an U5C.

DESIGN

Prospective observational study.

METHODS

Using routine provider-initiated HIV testing and counseling (PITC) registers, we prospectively studied 1757 children offered PITC at a government IC and U5C. Infants tested by HIV DNA polymerase chain reaction (PCR) were followed until PCR result disclosure or defaulting.

RESULTS

We sampled 877 and 880 consecutive PITC recipients at U5C and IC, respectively. Overall, a 7-fold greater proportion received PITC at IC (84.2% vs. 11.4%, P < 0.001). PITC recipients at IC were more than 14 months younger (2.6 vs. 17.0, P < 0.001), with greater proportions HIV exposed (17.6% vs. 5.3%, P < 0.001) and PCR eligible (7.9% vs. 3.5%, P < 0.001). A higher percentage of IC infants accepted PCR testing (100.0% vs. 90.3%, P = 0.03). Additionally, IC PCR recipients were 2.5 months younger (3.1 vs. 5.6, P < 0.001) with 4 times less testing PCR positive (7.1% vs. 32.1%, P < 0.001). Importantly, a more than 3-fold greater proportion of HIV-exposed infants at IC returned for their PCR result and enrolled into care (78.6% vs. 25.0%, P < 0.001).

CONCLUSIONS

Compared with an U5C, integrating EID testing into an IC is more acceptable, more feasible, enrolls more infants into EID at younger ages, and would likely strengthen Malawi's EID services if expanded.

Loss to Followup: A Major Challenge to Successful Implementation of Prevention of Mother-to-Child Transmission of HIV-1 Programs in Sub-Saharan Africa

Purpose. The purpose of this paper was to explore how loss to followup (LFTU) has affected the successful implementation of prevention of mother to child transmission of HIV-1 (PMTCT) programs in sub-Saharan Africa. Methods. We conducted an electronic search from the following databases PubMed, ScienceDirect, Directory of Open Access Journals (DOAJs), and PyscINFO. Additional searches were made in WHO, UNAIDS, UNICEF, Google, and Google scholar websites for (1) peer-reviewed published research, (2) scientific and technical reports, and (3) papers presented on scientific conferences. Results. A total of 678 articles, published from 1990 to 2011, were retrieved. Only 44 articles met our inclusion criteria and were included in the study. The rates of LTFU of mother-child pairs ranged from 19% to 89.4 in the reviewed articles. Health facility factors, fear of HIV-1 test, stigma and discrimination, home deliveries and socioeconomic factors were identified as reasons for LTFU. Conclusion. There is a great loss of mother-child pairs to follow up in PMTCT programs in sub-Saharan Africa. There is need for more research studies to develop public health models of care that can help to improve followup of mother-child pairs in PMTCT programs in Sub-Saharan Africa.

Addressing poor retention of infants exposed to HIV: a quality improvement study in rural Mozambique

OBJECTIVE

Early infant diagnosis (EID) is the first step in HIV care, yet 75% of HIV-exposed infants born at 2 hospitals in Mozambique failed to access EID.

DESIGN

Before/after study.

SETTING

Two district hospitals in rural Mozambique.

PARTICIPANTS

HIV-infected mother/HIV-exposed infant pairs (n = 791).

INTERVENTION

We planned 2 phases of improvement using quality improvement methods. In phase 1, we enhanced referral by offering direct accompaniment of new mothers to the EID suite, increasing privacy, and opening a medical record for infants before postpartum discharge. In phase 2, we added enhanced referral activity as an item on the maternity register to standardize the process of referral.

MAIN OUTCOME MEASURE

The proportion of HIV-infected mothers who accessed EID for their infant <90 days of life.

RESULTS

We tracked mother/infant pairs from June 2009 to March 2011 (phase 0: n = 144; phase 1: n = 479; phase 2: n = 168), compared study measures for mother/infant pairs across intervention phases with χ², estimated time-to-EID by Kaplan-Meier, and determined the likelihood of EID by Cox regression after adjusting for likely barriers to follow-up. At baseline (phase 0), 25.7% of infants accessed EID <90 days. EID improved to 32.2% after phase 1, but only 17.3% had received enhanced referral. After phase 2, 61.9% received enhanced referral and 39.9% accessed EID, a significant 3-phase improvement (P = 0.007). In adjusted analysis, the likelihood of EID at any time was higher in the phase 2 group versus phase 0 (adjusted hazard ratio: 1.68, 95% confidence interval: 1.19 to 2.37, P = 0.003).

CONCLUSIONS

Retention improved by 55% with a simple referral enhancement. Quality improvement efforts could help improve care in Mozambique and other low-resource countries [added].
