Planned delivery or expectant management for late preterm pre-eclampsia in low-income and middle-income countries (CRADLE-4): a multicentre, open-label, randomised controlled trial.

BACKGROUND: Pre-eclampsia is a leading cause of maternal and perinatal mortality. Evidence regarding interventions in a low-income or middle-income setting is scarce. We aimed to evaluate whether planned delivery between 34+ 0 and 36+ 6 weeks' gestation can reduce maternal mortality and morbidity without increasing perinatal complications in India and Zambia. METHODS: In this parallel-group, multicentre, open-label, randomised controlled trial, we compared planned delivery versus expectant management in women with pre-eclampsia from 34+ 0 to 36+ 6 weeks' gestation. Participants were recruited from nine hospitals and referral facilities in India and Zambia and randomly assigned to planned delivery or expectant management in a 1:1 ratio by a secure web-based randomisation facility hosted by MedSciNet. Randomisation was stratified by centre and minimised by parity, single-fetus pregnancy or multi-fetal pregnancy, and gestational age. The primary maternal outcome was a composite of maternal mortality or morbidity with a superiority hypothesis. The primary perinatal outcome was a composite of one or more of: stillbirth, neonatal death, or neonatal unit admission of more than 48 h with a non-inferiority hypothesis (margin of 10% difference). Analyses were by intention to treat, with an additional per-protocol analysis for the perinatal outcome. The trial was prospectively registered with ISRCTN, 10672137. The trial is closed to recruitment and all follow-up has been completed. FINDINGS: Between Dec 19, 2019, and March 31, 2022, 565 women were enrolled. 284 women (282 women and 301 babies analysed) were allocated to planned delivery and 281 women (280 women and 300 babies analysed) were allocated to expectant management. The incidence of the primary maternal outcome was not significantly different in the planned delivery group (154 [55%]) compared with the expectant management group (168 [60%]; adjusted risk ratio [RR] 0·91, 95% CI 0·79 to 1·05). The incidence of the primary perinatal outcome by intention to treat was non-inferior in the planned delivery group (58 [19%]) compared with the expectant management group (67 [22%]; adjusted risk difference -3·39%, 90% CI -8·67 to 1·90; non-inferiority p<0·0001). The results from the per-protocol analysis were similar. There was a significant reduction in severe maternal hypertension (adjusted RR 0·83, 95% CI 0·70 to 0·99) and stillbirth (0·25, 0·07 to 0·87) associated with planned delivery. There were 12 serious adverse events in the planned delivery group and 21 in the expectant management group. INTERPRETATION: Clinicians can safely offer planned delivery to women with late preterm pre-eclampsia, in a low-income or middle-income country. Planned delivery reduces stillbirth, with no increase in neonatal unit admissions or neonatal morbidity and reduces the risk of severe maternal hypertension. Planned delivery from 34 weeks' gestation should therefore be considered as an intervention to reduce pre-eclampsia associated mortality and morbidity in these settings.

Post-abortion care services in Zambian health facilities: a qualitative study of users' experiences and perceptions.

BACKGROUND: Despite attempts to increase Universal Health Coverage, availability, accessibility, acceptability, and quality-related challenges remain barriers to receiving essential services by women who need them. We aimed to explore the experiences and perceptions of women receiving post-abortal care services in Zambia, within a human-rights framework. METHODS: A qualitative case study was conducted between August and September 2021 in Lusaka and Copperbelt provinces of Zambia. Fifteen (15) women seeking post-abortion care services were` interviewed using audio recorders; transcribed data was analyzed using thematic analysis. We report women's experiences and perceptions of the healthcare system, their experiences of abortion, and healthcare-seeking behaviour. We used the availability, accessibility, acceptability, and quality (AAAQ) framework to understand how women claimed their right to healthcare as they sought and utilized post-abortion care services. RESULTS: Women who experienced spontaneous abortions delayed seeking health care by viewing symptoms as 'normal pregnancy symptoms' and not dangerous. Women also delayed seeking care because they feared the negative attitudes from their communities and the health care providers towards abortion in general, despite it being legal in Zambia. Some services were considered costly, impeding their right to access quality care. CONCLUSIONS: Women delayed seeking care compounded by fear of negative attitudes from the community and healthcare providers. To ensure the provision and utilization of quality all abortion-related healthcare services, there is a need to increase awareness of the availability and legality of safe abortion services, the importance of seeking healthcare early for any abortion-related discomfort, and the provision and availability of free services at all levels of care should be emphasized.

Unsafe abortions continue to be an avoidable public health concern both globally and locally. In Zambia, a fifth of maternal deaths are related to unsafe abortions. Unsafe abortions have been defined as any induced termination of pregnancy outside the health facility, performed by untrained health personnel. Several strides have been made including the provision of comprehensive abortion care in all facilities, and the training of health personnel to provide these services at different levels of healthcare. Despite the increased availability of comprehensive abortion care through liberalized abortion laws and regulations and the training of health personnel to provide these services at different levels of healthcare, the need for quality post-abortion care specifically persists. As such, we carried out in-depth interviews to explore the experiences of women who present at healthcare facilities in Lusaka and the Copperbelt provinces in Zambia seeking post-abortion services. It was found that delay in seeking care at a health facility was due to fear that the service is illegal; alongside judgment from health care providers and society for seeking such a service that is generally perceived as evil. The assumption that the cost of receiving such services is high and a general lack of awareness about the service being provided free was also expressed. The study highlighted the need for community awareness of the legal framework on abortions to ensure women access services at any time necessary without fear of being judged, which will consequently reduce the number of abortion-related disabilities and deaths.

Comprehensive pregnancy monitoring with a network of wireless, soft, and flexible sensors in high- and low-resource health settings.

Vital signs monitoring is a fundamental component of ensuring the health and safety of women and newborns during pregnancy, labor, and childbirth. This monitoring is often the first step in early detection of pregnancy abnormalities, providing an opportunity for prompt, effective intervention to prevent maternal and neonatal morbidity and mortality. Contemporary pregnancy monitoring systems require numerous devices wired to large base units; at least five separate devices with distinct user interfaces are commonly used to detect uterine contractility, maternal blood oxygenation, temperature, heart rate, blood pressure, and fetal heart rate. Current monitoring technologies are expensive and complex with implementation challenges in low-resource settings where maternal morbidity and mortality is the greatest. We present an integrated monitoring platform leveraging advanced flexible electronics, wireless connectivity, and compatibility with a wide range of low-cost mobile devices. Three flexible, soft, and low-profile sensors offer comprehensive vital signs monitoring for both women and fetuses with time-synchronized operation, including advanced parameters such as continuous cuffless blood pressure, electrohysterography-derived uterine monitoring, and automated body position classification. Successful field trials of pregnant women between 25 and 41 wk of gestation in both high-resource settings (n = 91) and low-resource settings (n = 485) demonstrate the system's performance, usability, and safety.

Diagnostic Accuracy of an Integrated AI Tool to Estimate Gestational Age From Blind Ultrasound Sweeps.

Importance: Accurate assessment of gestational age (GA) is essential to good pregnancy care but often requires ultrasonography, which may not be available in low-resource settings. This study developed a deep learning artificial intelligence (AI) model to estimate GA from blind ultrasonography sweeps and incorporated it into the software of a low-cost, battery-powered device. Objective: To evaluate GA estimation accuracy of an AI-enabled ultrasonography tool when used by novice users with no prior training in sonography. Design, Setting, and Participants: This prospective diagnostic accuracy study enrolled 400 individuals with viable, single, nonanomalous, first-trimester pregnancies in Lusaka, Zambia, and Chapel Hill, North Carolina. Credentialed sonographers established the "ground truth" GA via transvaginal crown-rump length measurement. At random follow-up visits throughout gestation, including a primary evaluation window from 14 0/7 weeks' to 27 6/7 weeks' gestation, novice users obtained blind sweeps of the maternal abdomen using the AI-enabled device (index test) and credentialed sonographers performed fetal biometry with a high-specification machine (study standard). Main Outcomes and Measures: The primary outcome was the mean absolute error (MAE) of the index test and study standard, which was calculated by comparing each method's estimate to the previously established GA and considered equivalent if the difference fell within a prespecified margin of ±2 days. Results: In the primary evaluation window, the AI-enabled device met criteria for equivalence to the study standard, with an MAE (SE) of 3.2 (0.1) days vs 3.0 (0.1) days (difference, 0.2 days [95% CI, -0.1 to 0.5]). Additionally, the percentage of assessments within 7 days of the ground truth GA was comparable (90.7% for the index test vs 92.5% for the study standard). Performance was consistent in prespecified subgroups, including the Zambia and North Carolina cohorts and those with high body mass index. Conclusions and Relevance: Between 14 and 27 weeks' gestation, novice users with no prior training in ultrasonography estimated GA as accurately with the low-cost, point-of-care AI tool as credentialed sonographers performing standard biometry on high-specification machines. These findings have immediate implications for obstetrical care in low-resource settings, advancing the World Health Organization goal of ultrasonography estimation of GA for all pregnant people.

'Moving towards understanding', acceptability of investigations following stillbirth in sub-Saharan Africa: A grounded theory study.

OBJECTIVE: To explore the views of women, partners, families, health workers and community leaders of potential investigations to determine the cause(s) of stillbirth, in Malawi, Tanzania and Zambia. DESIGN: Grounded theory. SETTING: Tertiary facilities and community settings in Blantyre, Malawi, Mwanza, Tanzania and Mansa, Zambia. SAMPLE: Purposive and theoretical sampling was used to recruit 124 participants: 33 women, 18 partners, 19 family members, 29 health workers and 25 community leaders, across three countries. METHODS: Semi-structured interviews were conducted using a topic guide for focus. Analysis was completed using constant comparative analysis. Sampling ceased at data saturation. RESULTS: Women wanted to know the cause of stillbirth, but this was tempered by their fear of the implications of this knowledge; in particular, the potential for them to be blamed for the death of their baby. There were also concerns about the potential consequences of denying tradition and culture. Non-invasive investigations were most likely to be accepted on the basis of causing less 'harm' to the baby. Parents' decision-making was influenced by type of investigation, family and cultural influences and financial cost. CONCLUSIONS: Parents want to understand the cause of death, but face emotional, cultural and economic barriers to this. Offering investigations will require these barriers to be addressed, services to be available and a no-blame culture developed to improve outcomes. Community awareness, education and support for parents in making decisions are vital prior to implementing investigations in these settings.

Risk of Adverse Birth Outcomes in Two Cohorts of Pregnant Women With HIV in Zambia.

BACKGROUND: A trial of progesterone to prevent preterm birth among HIV-infected Zambian women [Improving Pregnancy Outcomes with Progesterone (IPOP)] found no treatment effect, but the risk of the primary outcome was among the lowest ever documented in women with HIV. In this secondary analysis, we compare the risks of preterm birth (<37 weeks), stillbirth, and a composite primary outcome comprising the two in IPOP versus an observational pregnancy cohort [Zambian Preterm Birth Prevention Study (ZAPPS)] in Zambia, to evaluate reasons for the low risk in IPOP. METHODS: Both studies enrolled women before 24 gestational weeks, during August 2015-September 2017 (ZAPPS) and February 2018-January 2020 (IPOP). We used linear probability and log-binomial regression to estimate risk differences and risk ratios (RR), before and after restriction and standardization with inverse probability weights. RESULTS: The unadjusted risk of composite outcome was 18% in ZAPPS (N = 1450) and 9% in IPOP (N = 791) (RR = 2.0; 95% CI = 1.6, 2.6). After restricting and standardizing the ZAPPS cohort to the distribution of IPOP baseline characteristics, the risk remained higher in ZAPPS (RR = 1.6; 95% CI = 1.0, 2.4). The lower risk of preterm/stillbirth in IPOP was only partially explained by measured risk factors. CONCLUSIONS: Possible benefits in IPOP of additional monetary reimbursement, more frequent visits, and group-based care warrant further investigation.

Circulating angiogenic factors and HIV among pregnant women in Zambia: a nested case-control study.

BACKGROUND: Maternal HIV increases the risk of adverse birth outcomes including preterm birth, fetal growth restriction, and stillbirth, but the biological mechanism(s) underlying this increased risk are not well understood. We hypothesized that maternal HIV may lead to adverse birth outcomes through an imbalance in angiogenic factors involved in the vascular endothelial growth factor (VEGF) signaling pathway. METHODS: In a case-control study nested within an ongoing cohort in Zambia, our primary outcomes were serum concentrations of VEGF-A, soluble endoglin (sEng), placental growth factor (PlGF), and soluble fms-like tyrosine kinase-1 (sFLT-1). These were measured in 57 women with HIV (cases) and 57 women without HIV (controls) before 16 gestational weeks. We used the Wilcoxon rank-sum and linear regression controlling for maternal body mass index (BMI) and parity to assess the difference in biomarker concentrations between cases and controls. We also used logistic regression to test for associations between biomarker concentration and adverse pregnancy outcomes (preeclampsia, preterm birth, small for gestational age, stillbirth, and a composite of preterm birth or stillbirth). RESULTS: Compared to controls, women with HIV had significantly lower median concentrations of PlGF (7.6 vs 10.2 pg/mL, p = 0.02) and sFLT-1 (1647.9 vs 2055.6 pg/mL, p = 0.04), but these findings were not confirmed in adjusted analysis. PlGF concentration was lower among women who delivered preterm compared to those who delivered at term (6.7 vs 9.6 pg/mL, p = 0.03) and among those who experienced the composite adverse birth outcome (6.2 vs 9.8 pg/mL, p = 0.02). Median sFLT-1 concentration was lower among participants with the composite outcome (1621.0 vs 1945.9 pg/mL, p = 0.04), but the association was not significant in adjusted analysis. sEng was not associated with either adverse birth outcomes or HIV. VEGF-A was undetectable by Luminex in all specimens. CONCLUSIONS: We present preliminary findings that HIV is associated with a shift in the VEGF signaling pathway in early pregnancy, although adjusted analyses were inconclusive. We confirm an association between angiogenic biomarkers and adverse birth outcomes in our population. Larger studies are needed to further elucidate the role of HIV on placental angiogenesis and adverse birth outcomes.

Planned early delivery for late preterm pre-eclampsia in a low- and middle-income setting: a feasibility study.

BACKGROUND: Pre-eclampsia is a leading cause of maternal and perinatal mortality and morbidity globally. Planned delivery between 34+0 and 36+6 weeks may reduce adverse pregnancy outcomes but is yet to be evaluated in a low and middle-income setting. Prior to designing a randomised controlled trial to evaluate this in India and Zambia, we carried out a 6-month feasibility study in order to better understand the proposed trial environment and guide development of our intervention. METHODS: We used mixed methods to understand the disease burden and current management of pre-eclampsia at our proposed trial sites and explore the acceptability of the intervention. We undertook a case notes review of women with pre-eclampsia who delivered at the proposed trial sites over a 3-month period, alongside facilitating focus group discussions with women and partners and conducting semi-structured interviews with healthcare providers. Descriptive statistics were used to analyse audit data. A thematic framework analysis was used for qualitative data. RESULTS: Case notes data (n = 326) showed that in our settings, 19.5% (n = 44) of women with pre-eclampsia delivering beyond 34 weeks experienced an adverse outcome. In women delivering between 34+0 and 36+6 weeks, there were similar numbers of antenatal stillbirths [n = 3 (3.3%)] and neonatal deaths [n = 3 (3.4%)]; median infant birthweight was 2.2 kg and 1.9 kg in Zambia and India respectively. Lived experience of women and healthcare providers was an important facilitator to the proposed intervention, highlighting the serious consequences of pre-eclampsia. A preference for spontaneous labour and limited neonatal resources were identified as potential barriers. CONCLUSIONS: This study demonstrated a clear need to evaluate the intervention and highlighted several challenges relating to trial context that enabled us to adapt our protocol and design an acceptable intervention. Our study demonstrates the importance of assessing feasibility when developing complex interventions, particularly in a low-resource setting. Additionally, it provides a unique insight into the management of pre-eclampsia at our trial settings and an understanding of the knowledge, attitudes and beliefs underpinning the acceptability of planned early delivery.

Pre-eclampsia is a complication of pregnancy and is one of the major causes of pregnancy-related death and serious illness for women and babies around the world. Most of these deaths occur in lower income countries in Africa and Asia. Signs of pre-eclampsia include high blood pressure and protein in the urine. It is unpredictable and may affect different organs within the woman, leading to seizures, stroke and even death if not well managed. It can also affect the baby's growth and in severe cases lead to stillbirth. We know that birth of the baby (and placenta) is the only cure for pre-eclampsia. Currently, it is recommended by the World Health Organisation that all women with pre-eclampsia are offered planned early birth once they reach 37 weeks of pregnancy, unless they develop severe complications needing intervention sooner than this. However, research from higher income countries has shown that planned early birth from 34 weeks of pregnancy may reduce serious complications in the woman, without causing harm to the baby. We are designing a clinical trial to find out whether, in women with pre-eclampsia between 34 and 37 weeks of pregnancy, it is better to offer planned early birth or to offer close monitoring until either they reach 37 weeks, or a complication develops requiring emergency intervention. Before designing this trial, we carried out a study in order to establish whether the main trial would be possible, and acceptable to the local community, at our potential trial sites in India and Zambia.

A couple-focused, integrated unplanned pregnancy and HIV prevention program in urban and rural Zambia.

BACKGROUND: Zambia's total fertility rate (5 births per woman) and adult HIV prevalence (11.5%) are among the highest in the world, with heterosexual couples being the most affected group. Jointly counseling and testing couples for HIV has reduced up to 58% of new HIV infections in Zambian clinics. Married women using contraceptives in Zambia have a high (20%) unmet need for family planning and low (8.6%) uptake of cost-effective long-acting reversible contraceptives. We present an integrated counseling, testing, and family-planning program to prevent HIV and unplanned pregnancy in Zambia. OBJECTIVE: The objective of this study was to integrate effective HIV prevention and family-planning services for Zambian couples. STUDY DESIGN: A 3 year program (2013-2016) progressively integrated the promotion and provision of couples' voluntary HIV counseling and testing and long-acting reversible contraceptives. The program was based in 55 urban and 215 rural government clinics across 33 districts. In the first year, a couples' family-planning counseling training program was developed and combined with existing couples HIV counseling training materials. To avoid congestion during routine clinic hours, joint counseling services were initially provided on weekends, while nurses were trained in intrauterine device and hormonal implant insertion and removal during weekday family-planning services. Demand was created through mutual referral between weekend and weekday programs and by clinic staff, community health workers, and satisfied family-planning clients. When the bulk of integrated service training was completed, the program transitioned services to routine weekday clinic hours, ensuring access to same-day services. Performance indicators included number of staff trained, clients served, integrated service referrals, HIV infections averted, and unplanned pregnancies averted. RESULTS: A stepwise approach trained high-performing service providers to be trainers and used high-volume clinics for practicum training of the next generation. In total, 1201 (391 urban, 810 rural) counselors were trained and served 120,535 urban and 87,676 rural couples. In urban clinics, 236 nurses inserted 65,619 long-acting reversible contraceptives, while in rural clinics, 243 nurses inserted 35,703 implants and intrauterine devices. The program prevented an estimated 12,869 urban and 8279 rural adult HIV infections, and 98,626 unintended urban pregnancies. In the final year, the proportion of clients receiving joint counseling services on weekdays rose from 11% to 89%, with many referred from within clinics including HIV testing and treatment services (32%), outpatient department (31%), family planning (16%), and infant vaccination (15%). The largest group of clients requesting long-acting reversible contraceptives (45%) did so after joint fertility goal-based counseling, confirming the high impact of this couple-focused demand creation approach. Remaining family-planning clients responded to referrals from clinic nurses (34%), satisfied implant/intrauterine device users (13%), or community health workers (8%). CONCLUSION: Integrated HIV and unplanned pregnancy prevention can be implemented in low-resource public sector facilities. Combination services offered to couples mutually leverage HIV prevention and unplanned pregnancy prevention. The addition of long-acting reversible contraceptives is an important complement to the method mix available in government clinics. Demand creation in the clinic and in the community must be coordinated with a growing supply of well-trained providers.

Fertility intentions and long-acting reversible contraceptive use among HIV-negative single mothers in Zambia.

BACKGROUND: Integrating family planning interventions with HIV studies in developing countries has been shown to prevent mother-to-child HIV transmission and simultaneously reduce HIV and unintended pregnancy in high-risk populations. As part of a prospective cohort study on HIV incidence and risk factors in Zambian women having unprotected sex, we also offered family planning counseling and immediate access to long-acting reversible contraceptives. Although long-acting reversible contraceptives are the most effective form of contraception, many Zambian women are limited to oral or injectable methods because of a lack of knowledge or method availability. This project offers to single mothers who are enrolled in a cohort study information about and access to long-acting reversible contraceptives at enrollment and at each follow-up visit. OBJECTIVE: This study evaluates how fertility intentions affect long-acting reversible contraceptive use in HIV-negative single mothers in Zambia. Our primary outcome was long-acting reversible contraceptive use throughout the study participation. We also estimated rates of long-acting reversible contraceptive uptake and discontinuation. We specifically studied single mothers because they are at high risk for unintended pregnancy, which can have significant negative ramifications on their financial, social, and psychologic circumstances. STUDY DESIGN: From 2012-2017, Zambia Emory HIV Research Project recruited 521 HIV-negative single mothers ages 18-45 years from government clinics in Lusaka and Ndola, Zambia's 2 largest cities. Participants were followed every 3 months for up to 5 years. At each visit, we discussed fertility goals and contraceptive options and offered a long-acting reversible method to any woman who was not pregnant or who already was using a long-acting reversible or permanent contraceptive method. Data were collected on demographic factors, sexual behavior, and reproductive history. Multivariable logistic regression was used to model baseline fertility intentions with long-acting reversible contraceptive use. RESULTS: We enrolled 518 women; 57 women did not return for any follow-up visits. There was a significant increase in long-acting reversible contraceptive use during the study. At baseline, 93 of 518 women (18%) were using a long-acting reversible method, and 151 of 461 women (33%) used a long-acting reversible method at the end of follow-up period (P<.0001). Four women chose an intrauterine device, and 91 women chose an implant for their first uptake event. After we adjusted the data for other confounders, we found that women in Ndola who did not desire any more children were more likely to use a long-acting reversible contraceptive (adjusted prevalence ratio, 2.02; 95% confidence interval, 1.88-3.42). During follow up, 37 of 183 long-acting reversible contraceptive users (20%) discontinued their method; women who desired future children at baseline were more likely to discontinue earlier (P=.016). CONCLUSION: This study demonstrates that integrated family planning services can increase long-acting reversible contraceptive use successfully among Zambian single mothers, who are a vulnerable population that disproportionately is affected by unintended pregnancy. A steady increase in use over time confirms the importance of repeated messaging about these unfamiliar methods. Thus, it is imperative that family planning interventions target single mothers in developing countries to promote effective contraceptive use.

Journey of vulnerability: a mixed-methods study to understand intrapartum transfers in Tanzania and Zambia.

BACKGROUND: Timely intrapartum referral between facilities is pivotal in reducing maternal/neonatal mortality and morbidity but is distressing to women, resource-intensive and likely to cause delays in care provision. We explored the complexities around referrals to gain understanding of the characteristics, experiences and outcomes of those being transferred. METHODS: We used a mixed-method parallel convergent design, in Tanzania and Zambia. Quantitative data were collected from a consecutive, retrospective case-note review (target, n = 2000); intrapartum transfers and stillbirths were the outcomes of interest. A grounded theory approach was adopted for the qualitative element; data were collected from semi-structured interviews (n = 85) with women, partners and health providers. Observations (n = 33) of transfer were also conducted. Quantitative data were analysed descriptively, followed by binary logistic regression models, with multiple imputation for missing data. Qualitative data were analysed using Strauss's constant comparative approach. RESULTS: Intrapartum transfer rates were 11% (111/998; 2 unknown) in Tanzania and 37% (373/996; 1 unknown) in Zambia. Main reasons for transfer were prolonged/obstructed labour and pre-eclampsia/eclampsia. Women most likely to be transferred were from Zambia (as opposed to Tanzania), HIV positive, attended antenatal clinic < 4 times and living > 30 min away from the referral hospital. Differences were observed between countries. Of those transferred, delays in care were common and an increase in poor outcomes was observed. Qualitative findings identified three categories: social threats to successful transfer, barriers to timely intrapartum care and reparative interventions which were linked to a core category: journey of vulnerability. CONCLUSION: Although intrapartum transfers are inevitable, modifiable factors exist with the potential to improve the experience and outcomes for women. Effective transfers rely on adequate resources, effective transport infrastructures, social support and appropriate decision-making. However, women's (and families) vulnerability can be reduced by empathic communication, timely assessment and a positive birth outcome; this can improve women's resilience and influence positive decision-making, for the index and future pregnancy.

The WOMAN trial: clinical and contextual factors surrounding the deaths of 483 women following post-partum haemorrhage in developing countries.

BACKGROUND: Post-partum haemorrhage (PPH) is a leading cause of maternal death worldwide. The WOMAN trial assessed the effects of tranexamic acid (TXA) on death and surgical morbidity in women with PPH. The trial recorded 483 maternal deaths. We report the circumstances of the women who died. METHODS: The WOMAN trial recruited 20,060 women with a clinical diagnosis of PPH after a vaginal birth or caesarean section. We randomly allocated women to receive TXA or placebo. When a woman died, we asked participating clinicians to report the cause of death and to provide a short narrative of the events surrounding the death. We collated and edited for clarity the narrative data. RESULTS: Case fatality rates were 3.0% in Africa and 1.7% in Asia. Nearly three quarters of deaths were within 3 h of delivery and 91% of these deaths were from bleeding. Women who delivered outside a participating hospital (12%) were three times more likely to die (OR = 3.12, 95%CI 2.55-3.81) than those who delivered in hospital. Blood was often unavailable due to shortages or because relatives could not afford to buy it. Clinicians highlighted late presentation, maternal anaemia and poor infrastructure as key contributory factors. CONCLUSIONS: Although TXA use reduces bleeding deaths by almost one third, mortality rates similar to those in high income countries will not be achieved without tackling late presentation, maternal anaemia, availability of blood for transfusion and poor infrastructure.

National policies and care provision in pregnancy and childbirth for twins in Eastern and Southern Africa: A mixed-methods multi-country study.

BACKGROUND: High-risk pregnancies, such as twin pregnancies, deserve particular attention as mortality is very high in this group. With a view to inform policy and national guidelines development for the Sustainable Development Goals, we reviewed national training materials, guidelines, and policies underpinning the provision of care in relation to twin pregnancies and assessed care provided to twins in 8 Eastern and Southern African countries: Kenya, Malawi, Mozambique, Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe. METHODS AND FINDINGS: We located policies and guidelines by reviewing national repositories and by contacting experts to systematically map country-level maternal and newborn training materials, guidelines, and policies. We extracted recommendations for care for twins spanning ante-, intra-, and postpartum care that typically should be offered during twin pregnancies and childbirth. We compared care provided for mothers of twins to that provided for mothers of singletons during the ante-, intra-, and postpartum period and computed neonatal mortality rates using the most recent Demographic and Health Surveys (DHS) data for each country. There was a paucity of guidance on care specifically for twin or multiple pregnancies: None of the countries provided clear guidance on additional number of antenatal care visits or specific antenatal content, while 7 of the 8 countries recommended twins to be delivered in a comprehensive emergency obstetric and neonatal care facility. These results were mirrored by DHS results of 73,462 live births (of which 1,360 were twin) indicating that twin pregnancies did not receive more frequent or intensified antenatal care. The percentage of twin deliveries in hospitals varied from 25.3% in Mozambique to 63.0% in Kenya, and women with twin deliveries were between 5 and 27 percentage points more likely to deliver in hospitals compared to women with singleton live births; this difference was significant in 5 of the 8 countries (t test p < 0.05). The percentage of twin deliveries by cesarean section varied from 9% in Mozambique to 36% in Rwanda. The newborn mortality rate among twins, adjusted for maternal age and parity, was 4.6 to 7.2 times higher for twins compared to singletons in all 8 countries. CONCLUSIONS: Despite the limited sample size and the limited number of clinically relevant services evaluated, our study provided evidence that mothers of twins receive insufficient care and that mortality in twin newborns is very high in Eastern and Southern Africa. Most countries have insufficient guidelines for the care of twins. While our data do not allow us to make a causal link between insufficient guidelines and insufficient care, they call for an assessment and reconceptualisation of policies to reduce the unacceptably high mortality in twins in Eastern and Southern Africa.

Intramuscular 17-hydroxyprogesterone caproate to prevent preterm birth among HIV-infected women in Zambia: study protocol of the IPOP randomized trial.

BACKGROUND: Each year, an estimated 15 million babies are born preterm, a global burden borne disproportionately by families in lower-income countries. Maternal HIV infection increases a woman's risk of delivering prematurely, and antiretroviral therapy (ART) may compound this risk. While prenatal progesterone prophylaxis prevents preterm birth among some high-risk women, it is unknown whether HIV-infected women could benefit from this therapy. We are studying the efficacy of progesterone supplementation to reduce the risk of preterm birth among pregnant women with HIV in Lusaka, Zambia. METHODS: The Improving Pregnancy Outcomes with Progesterone (IPOP) study is a Phase III double-masked, placebo-controlled, randomized trial of intramuscular 17-alpha hydroxprogesterone caproate (17P) to prevent preterm birth in HIV-infected women. A total of 800 women will be recruited prior to 24 weeks of gestation and randomly allocated to 17P or placebo administered by weekly intramuscular injection. The primary outcome will be a composite of live birth prior to 37 completed gestational weeks or stillbirth at any gestational age. Secondary outcomes will include very preterm birth (< 34 weeks), extreme preterm birth (< 28 weeks), small for gestational age (<10th centile), low birth weight (< 2500 g), and neonatal outcomes. In secondary analysis, we will assess whether specific HIV-related covariates, including the timing of maternal ART initiation relative to conception, is associated with progesterone's prophylactic efficacy, if any. DISCUSSION: We hypothesize that weekly prenatal 17P will reduce the risk of HIV-related preterm birth. An inexpensive intervention to prevent preterm birth among pregnant women with HIV could have substantial global public health impact. TRIAL REGISTRATION: NCT03297216 ; September 29, 2017.

Comparing women's financial costs of induced abortion at a facility vs. seeking treatment for complications from unsafe abortion in Zambia.

Although abortion is legal in Zambia under a variety of broad conditions, unsafe abortion remains common. The purpose of this project was to compare the financial costs for women when they have an induced abortion at a facility, with costs for an induced abortion outside a facility, followed by care for abortion-related complications. We gathered household wealth data at one point in time (T1) and longitudinal qualitative data at two points in time (T1 and T2, three-four months later), in Lusaka and Kafue districts, between 2014 and 2015. The data were collected from women (n = 38) obtaining a legal termination of pregnancy (TOP), or care for unsafe abortions (CUA). The women were recruited from four health facilities (two hospitals and two private clinics, one of each per district). At T2, CUA cost women, on average, 520 ZMW (USD 81), while TOP cost women, on average, 396 ZMW (USD 62). About two-thirds of the costs had been incurred by T1, while an additional one-third of the total costs was incurred between T1 and T2. Women in all three wealth tertiles sought a TOP in a health facility or an unsafe abortion outside a facility. Women who obtained CUA tended to be further removed from the money that was used to pay for their abortion care. Women's financial dependence leaves them unequipped to manage a financial shock such as an abortion. Improved TOP and post-abortion care are needed to reduce the health sequelae women experience after both types of abortion-related care.

Sustained effect of couples' HIV counselling and testing on risk reduction among Zambian HIV serodiscordant couples.

BACKGROUND: We present temporal trends in self-reported and biological markers of unprotected sex and sex with concurrent partners in discordant couples receiving couples' voluntary HIV counselling and testing (CVCT). METHODS: Heterosexual Zambian HIV-serodiscordant couples were enrolled into longitudinal follow-up in an open cohort (1994-2012). Multivariable Anderson-Gill models explored predictors of self-report and biological indicators of unprotected sex within (including sperm on a vaginal swab, incident pregnancy or incident linked HIV infection) and outside (including self-report, STI and unlinked HIV infection) the union. Measures of secular trends in baseline measures were also examined. RESULTS: At enrolment of 3049 couples, men were 35 years old on average, women were 29 years, and couples had been together for an average of 7 years. M+F- couples reported an average of 16.6 unprotected sex acts in the 3 months prior to enrolment (pre-CVCT), dropping to 5.3 in the >0-3 month interval, and 2.0 in >6 month intervals (p-trend <0.001). Corresponding values for M-F+ couples were 22.4 unprotected sex acts in the 3 months prior enrolment, dropping to 5.2 in the >0-3 month interval, and 3.1 in >6 month intervals (p-trend <0.001). Significant reductions in self-report and biological markers of outside partners were also noted. Predictors of unprotected sex between study partners after CVCT included prevalent pregnancy (adjusted HR, aHR=1.6-1.9); HIV+ men being circumcised (aHR=1.2); and HIV- women reporting sex with outside partners (aHR=1.3), alcohol (aHR=1.2), injectable (aHR=1.4) or oral (aHR=1.4) contraception use. Fertility intentions were also predictive of unprotected sex (aHR=1.2-1.4). Secular trends indicated steady declines in reported outside partners and STIs. CONCLUSION: Reductions in self-reported unprotected sex after CVCT were substantial and sustained. Reinforced risk-reduction counselling in pregnant couples, couples desiring children and couples with HIV- women having outside partners or using alcohol or injectable or oral contraception are indicated.

Risky Sex and HIV Acquisition Among HIV Serodiscordant Couples in Zambia, 2002-2012: What Does Alcohol Have To Do With It?

In this paper we evaluate the effects of heavy alcohol consumption on sexual behavior, HIV acquisition, and antiretroviral treatment (ART) initiation in a longitudinal open cohort of 1929 serodiscordant couples in Lusaka, Zambia from 2002 to 2012. We evaluated factors associated with baseline heavy alcohol consumption and its association with condomless sex with the study partner, sex outside of the partnership, and ART initiation using multivariable logistic regression. We estimated the effect of alcohol consumption on HIV acquisition using multivariable Cox models. Baseline factors significantly associated with women's heavy drinking (drunk weekly or more in 12-months before enrollment) included woman's older age (adjusted prevalence odds ratio [aPOR] = 1.04), partner heavy drinking (aPOR = 3.93), and being HIV-infected (aPOR = 2.03). Heavy drinking among men was associated with less age disparity with partner (aPOR per year disparity = 0.97) and partner heavy drinking (aPOR = 1.63). Men's being drunk daily (aOR = 1.18), women's being drunk less than monthly (aOR = 1.39) vs. never drunk and being in a male HIV-negative and female HIV-positive union (aOR = 1.45) were associated with condomless sex. Heavy alcohol use was associated with having 1 or more outside sex partners among men (aOR drunk daily = 1.91, drunk weekly = 1.32, drunk monthly = 2.03 vs. never), and women (aOR drunk monthly = 2.75 vs. never). Being drunk weekly or more increased men's risk of HIV acquisition (adjusted hazard ratio [aHR] = 1.72). Men and women being drunk weekly or more was associated (p < 0.1) with women's seroconversion (aHR = 1.42 and aHR = 3.71 respectively). HIV-positive women who were drunk monthly or more had lower odds of initiating ART (aOR = 0.83; 95% CI = 0.70-0.99) adjusting for age, months since baseline and previous pregnancies. Individuals in HIV-serodiscordant couples who reported heavy drinking had more outside sex partnerships and condomless sex with their study partner and were more likely to acquire HIV. HIV-positive women had lower odds of initiating ART if they were heavy drinkers.

Signal functions for emergency obstetric care as an intervention for reducing maternal mortality: a survey of public and private health facilities in Lusaka District, Zambia.

BACKGROUND: Zambia's maternal mortality ratio was estimated at 398/100,000 live births in 2014. Successful aversion of deaths is dependent on availability and usability of signal functions for emergency obstetric and neonatal care. Evidence of availability, usability and quality of signal functions in urban settings in Zambia is minimal as previous research has evaluated their distribution in rural settings. This survey evaluated the availability and usability of signal functions in private and public health facilities in Lusaka District of Zambia. METHODS: A descriptive cross sectional study was conducted between November 2014 and February 2015 at 35 public and private health facilities. The Service Availability and Readiness Assessment tool was adapted and administered to overall in-charges, hospital administrators or maternity ward supervisors at health facilities providing maternal and newborn health services. The survey quantified infrastructure, human resources, equipment, essential drugs and supplies and used the UN process indicators to determine availability, accessibility and quality of signal functions. Data on deliveries and complications were collected from registers for periods between June 2013 and May 2014. RESULTS: Of the 35 (25.7% private and 74.2% public) health facilities assessed, only 22 (62.8%) were staffed 24 h a day, 7 days a week and had provided obstetric care 3 months prior to the survey. Pre-eclampsia/ eclampsia and obstructed labor accounted for most direct complications while postpartum hemorrhage was the leading cause of maternal deaths. Overall, 3 (8.6%) and 5 (14.3%) of the health facilities had provided Basic and Comprehensive EmONC services, respectively. All facilities obtained blood products from the only blood bank at a government referral hospital. CONCLUSION: The UN process indicators can be adequately used to monitor progress towards maternal mortality reduction. Lusaka district had an unmet need for BEmONC as health facilities fell below the minimum UN standard. Public health facilities with capacity to perform signal functions should be upgraded to Basic EmONC status. Efforts must focus on enhancing human resource capacity in EmONC and improving infrastructure and supply chain. Obstetric health needs and international trends must drive policy change.

Hormonal Contraceptive Use Among HIV-Positive Women and HIV Transmission Risk to Male Partners, Zambia, 1994-2012.

BACKGROUND: Evidence on the association between female-to-male human immunodeficiency virus (HIV) transmission risk and hormonal contraception is sparse and conflicting. METHODS: Heterosexual HIV-discordant couples from Lusaka, Zambia, were followed longitudinally at 3 month-intervals from 1994 to 2012. The impact of hormonal contraception on time to HIV transmission from HIV-positive women to their HIV-negative male partners (M-F+) was evaluated. RESULTS: Among 1601 M-F+ couples, 171 genetically linked HIV transmissions occurred in men over 3216 couple-years (5.3 transmissions/100 couple-years; 95% confidence interval [CI], 4.5-6.2). In multivariable Cox models, neither injectable (adjusted hazard ratio [aHR], 0.6; 95% CI, .4-1.2), oral contraceptive pill (aHR, 0.8; 95% CI, .3-2.1), nor implant (aHR, 0.8; 95% CI, .5-1.4) use was associated with HIV transmission, relative to nonhormonal methods, after controlling for the man's age at baseline and time-varying measures of pregnancy, self-reported unprotected sex with the study partner, sperm present on a vaginal swab wet mount, genital inflammation of either partner, genital ulceration of the man, and first follow-up interval. Sensitivity analyses, including marginal structural modeling and controlling for viral load and fertility intentions available in a subset of couples, led to similar conclusions. CONCLUSIONS: Our findings suggest null associations between hormonal contraception and risk of female-to-male HIV transmission. We support efforts to increase the contraceptive method mix for all women, regardless of HIV serostatus, along with reinforced condom counseling for HIV-serodiscordant couples.
