The influence of individual provider characteristics and attitudes on caesarean section decision-making: a global review

Caesarean section (CS) rates have risen worldwide in the past two decades, particularly in middle and high-income countries. In addition to changing maternal and health system factors, there is growing evidence that provider factors may contribute to rising unnecessary caesareans. The aim of this review was to assess the evidence for the association between individual provider characteristics, attitudes towards CS and decision-making for CS. A search was conducted in May 2018 in PubMed and Web of Science with 23 papers included in our final review. Our results show that higher anxiety scores and more favourable opinions of CS were associated with increased likelihood of performing CS. These findings highlight a need for appropriate interventions to target provider attitudes towards CS to reduce unnecessary procedures

Measuring the unmet need for caesarean sections in sub-Saharan Africa and South Asia

Background. Caesarean sections are critical interventions in obstetric care. The unmet need for caesareans is an important indicator for monitoring emergency obstetric care coverage: several methods have been proposed, however there is no consensus on how to measure the unmet need for caesareans in sub-Saharan Africa and South Asia. Methods. First, trends in the caesarean rate by wealth were analysed in 26 countries in sub-Saharan Africa and South Asia using Demographic and Health Surveys, in order to identify groups with rates below 1% and 2%. Second, a global online survey was conducted on obstetricians’ opinions of the optimal caesarean rate. Third, linked hospital and population-based data were used to validate the Unmet Obstetric Need (UON) indicator in central Ghana, which measures the unmet need for surgery for absolute maternal indications (AMIs), and to investigate novel approaches using hospital data. Results. The caesarean rate was extremely low among poor women in most sub-Saharan African and South Asian countries. The median optimal caesarean rate reported by obstetricians worldwide was 20%, and there was a large variation in responses (IQR: 15-30%). The 1.4% threshold for the UON indicator was found not to be valid in Ghana. For most complications – including AMIs, among which caesarean rates were close to 100% – women were equally likely to have their need for caesareans met regardless of their educational level. Conclusion. The optimal caesarean rate remains unknown, and thus cannot be used as a benchmark for measuring the unmet need. The UON indicator does not produce valid estimates of AMI-related mortality avertable with caesareans, however caesarean rates below 1% probably indicate a critical unmet need for life-saving surgery. Comparing caesarean rates in hospitals by education is useful for determining whether population-based differences in the caesarean rate are partly explained by differential access to care within facilities

Changes over time in HIV testing and counselling uptake and associated factors among youth in Zambia: a cross-sectional analysis of demographic and health surveys from 2007 to 2018

Introduction: Zambia is among the countries with the highest HIV burden and where youth remain disproportionally affected. Access to HIV testing and counselling (HTC) is a crucial step to ensure the reduction of HIV transmission. This study examines the changes that occurred between 2007 and 2018 in access to HTC, inequities in testing uptake, and determinants of HTC uptake among youth. Methods: We carried out repeated cross-sectional analyses using three Zambian Demographic and Health Surveys (2007, 2013–14, and 2018). We calculated the percentage of women and men ages 15–24 years old who were tested for HIV in the last 12 months. We analysed inequity in HTC coverage using indicators of absolute inequality. We performed bivariate and multivariate logistic regression analyses to identify predictors of HTC uptake in the last 12 months. Results: HIV testing uptake increased between 2007 and 2018, from 45 to 92% among pregnant women, 10 to 58% among non-pregnant women, and from 10 to 49% among men. By 2018 roughly 60% of youth tested in the past 12 months used a government health centre. Mobile clinics were the second most common source reaching up to 32% among adolescent boys by 2018. Multivariate analysis conducted among men and non-pregnant women showed higher odds of testing among 20–24 year-olds than adolescents (aOR = 1.55 [95%CI:1.30–1.84], among men; and aOR = 1.74 [1.40–2.15] among women). Among men, being circumcised (aOR = 1.57 [1.32–1.88]) and in a union (aOR = 2.44 [1.83–3.25]) were associated with increased odds of testing. For women greater odds of testing were associated with higher levels of education (aOR = 6.97 [2.82–17.19]). Education-based inequity was considerably widened among women than men by 2018. Conclusion: HTC uptake among Zambian youth improved considerably by 2018 and reached 65 and 49% tested in the last 12 months for women and men, respectively. However, achieving the goal of 95% envisioned by 2020 will require sustaining the success gained through government health centres, and scaling up the community-led approaches that have proven acceptable and effective in reaching young men and adolescent girls who are less easy to reach through the government facilities

Comparing the use and content of antenatal care in adolescent and older first-time mothers in 13 countries of west Africa: a cross-sectional analysis of Demographic and Health Surveys

Background West Africa has the highest proportion of married adolescents, and the highest adolescent childbirth rate and maternal death rate in sub-Saharan Africa. However, few studies have focused on the type and quality of health care accessed by pregnant young women in countries in this subregion. Methods We obtained data from Demographic and Health Surveys done between 2010 and 2014, to compare the use, timing, source, and components of antenatal care between adolescent and older first-time mothers in 13 west African countries. The sample included primiparous women who were aged 15–49 years with a livebirth in the 5-year survey recall period, and women were assigned to one of three groups on the basis of age at the time of childbirth: adolescent (10–19 years), young adults (20–24 years), or adults (25 years or older). We calculated the percentage of women who: attended at least one antenatal care visit, completed at least one visit during the first trimester of pregnancy, attended four or more appointments in antenatal care, and received four components of antenatal care (blood pressure measurement, urine tests, blood tests, and information on complications), as well as the sector where the women received care. We primarily report the comparison between adolescents and young adults. Findings In 2016, we acquired data from the Demographic Health Surveys from 13 west African countries between 2010 and 2014 on primiparous women. The study sample was 19 211 women, of whom 10 025 (52%) were adolescents, 6099 (32%) were young adults, and 3087 (16%) were adults. Overall, 17 386 (91%) of 19 211 first-time mothers made use of antenatal care facilities on at least one occasion. 3597 (41%) of 8741 adolescents compared with 8202 (47%) of all 17 386 women began the use of antenatal care during the first trimester. Across west Africa, 5430 (62%) of 8741 adolescents had four or more antenatal care visits compared with 4067 (71%) of 5717 young adults and 2358 (81%) of 2928 adults. Of those who had four or more visits to antenatal care, 2779 (51%) of 5430 adolescents received all the antenatal care components examined compared with 2488 (61%) of 4067 young adults and 1600 (68%) of 2358 adults. Although most women received antenatal care in the public sector, in nine of the 13 countries, the proportion of women that used the private sector was higher in older mothers. Interpretation Although a large percentage of west African adolescents use some antenatal care for their first birth, they seek care later, make fewer visits during pregnancy, and receive fewer components of care than older first-time mothers. Governments must ensure the pregnancy care accessed by adolescent mothers is of high quality and tailored to meet their needs

Lessons learned from using linked administrative data to evaluate the Family Nurse Partnership in England and Scotland

Introduction “Big data” – including linked administrative data – can be exploited to evaluate interventions for maternal and child health, providing time- and cost-effective alternatives to randomised controlled trials. However, using these data to evaluate population-level interventions can be challenging. Objectives We aimed to inform future evaluations of complex interventions by describing sources of bias, lessons learned, and suggestions for improvements, based on two observational studies using linked administrative data from health, education and social care sectors to evaluate the Family Nurse Partnership (FNP) in England and Scotland. Methods We first considered how different sources of potential bias within the administrative data could affect results of the evaluations. We explored how each study design addressed these sources of bias using maternal confounders captured in the data. We then determined what additional information could be captured at each step of the complex intervention to enable analysts to minimise bias and maximise comparability between intervention and usual care groups, so that any observed differences can be attributed to the intervention. Results Lessons learned include the need for i) detailed data on intervention activity (dates/geography) and usual care; ii) improved information on data linkage quality to accurately characterise control groups; iii) more efficient provision of linked data to ensure timeliness of results; iv) better measurement of confounding characteristics affecting who is eligible, approached and enrolled. Conclusions Linked administrative data are a valuable resource for evaluations of the FNP national programme and other complex population-level interventions. However, information on local programme delivery and usual care are required to account for biases that characterise those who receive the intervention, and to inform understanding of mechanisms of effect. National, ongoing, robust evaluations of complex public health evaluations would be more achievable if programme implementation was integrated with improved national and local data collection, and robust quasi-experimental designs

Caesarean Section Provision and Capacity in Health Facilities in Tanzania

The national caesarean rate in Tanzania increased from 2% in 1996 to 6% in 2015-16 (3x increase). Over the same period, the absolute number of caesareans performed increased from 26,000/year to 118,000/year (5x increase). Continuous electricity is widely available in facilities performing caesareans, however availability of trained anaesthesia staff and general anaesthesia equipment is low, compromising the safety of caesarean sections. Several recommendations emerge from our findings to enhance safe caesarean care in Tanzania: (1) improve the availability of anaesthesia equipment and providers, (2) improve the environment for quality surgical services, (3) focus improvement efforts on public and FBO hospitals first, (4) support caesarean providers in low-volume facilities, (5) review the target on surgical provision in health centres, and (6) investigate adherence to infection prevention and control measures

Risk factors for peripartum hysterectomy among women with postpartum haemorrhage: analysis of data from the WOMAN trial.

BACKGROUND: Peripartum hysterectomy can cause significant morbidity and mortality. Most studies of peripartum hysterectomy are from high income countries. This cohort study examined risk factors for peripartum hysterectomy using data from Africa, Asia, Europe and the Americas. METHODS: We used data from the World Maternal Antifibrinolytic (WOMAN) trial carried out in 193 hospitals in 21 countries. Peripartum hysterectomy was defined as hysterectomy within 6 weeks of delivery as a complication of postpartum haemorrhage. Univariable and multivariable random effects logistic regression models were used to analyse risk factors. A hierarchical conceptual framework guided our multivariable analysis. RESULTS: Five percent of women had a hysterectomy (1020/20,017). Haemorrhage from placenta praevia/accreta carried a higher risk of hysterectomy (17%) than surgical trauma/tears (5%) and uterine atony (3%). The adjusted odds ratio (AOR) for hysterectomy in women with placenta praevia/accreta was 3.2 (95% CI: 2.7-3.8), compared to uterine atony. The risk of hysterectomy increased with maternal age. Caesarean section was associated with fourfold higher odds of hysterectomy than vaginal delivery (AOR 4.3, 95% CI: 3.6-5.0). Mothers in Asia had a higher hysterectomy incidence (7%) than mothers in Africa (5%) (AOR: 1.2, 95% CI: 0.9-1.7). CONCLUSIONS: Placenta praevia/accreta is associated with a higher risk of peripartum hysterectomy. Other risk factors for hysterectomy are advanced maternal age, caesarean section and giving birth in Asia

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente
