Using clinical cascades to measure health facilities' obstetric emergency readiness: testing the cascade model using cross-sectional facility data in East Africa

OBJECTIVES

Globally, hundreds of women die daily from preventable pregnancy-related causes, with the greatest burden in sub-Saharan Africa. Five key emergencies-bleeding, infections, high blood pressure, delivery complications and unsafe abortions-account for nearly 75% of these obstetric deaths. Skilled clinicians with strategic supplies could prevent most deaths. In this study, we (1) measured facility readiness to manage common obstetric emergencies using the clinical cascades and signal function tracers; (2) compared these readiness estimates by facility characteristics; and (3) measured cascading drop-offs in resources.

DESIGN

A facility-based cross-sectional analysis of resources for common obstetric emergencies.

SETTING

Data were collected in 2016 from 23 hospitals (10 designated comprehensive emergency obstetric care (CEmOC) facilities) in Migori County, western Kenya, and Busoga Region, eastern Uganda, in the Preterm Birth Initiative study in East Africa. Baseline data were used to estimate a facility's readiness to manage common obstetric emergencies using signal function tracers and the clinical cascade model. We compared emergency readiness using the proportion of facilities with tracers (signal functions) and the proportion with resources for identifying and treating the emergency (cascade stages 1 and 2).

RESULTS

The signal functions overestimated practical emergency readiness by 23 percentage points across five emergencies. Only 42% of CEmOC-designated facilities could perform basic emergency obstetric care. Across the three stages of care (identify, treat and monitor-modify) for five emergencies, there was a 28% pooled mean drop-off in readiness. Across emergencies, the largest drop-off occurred in the treatment stage. Patterns of drop-off remained largely consistent across facility characteristics.

CONCLUSIONS

Accurate measurement of obstetric emergency readiness is a prerequisite for strengthening facilities' capacity to manage common emergencies. The cascades offer stepwise, emergency-specific readiness estimates designed to guide targeted maternal survival policies and programmes.

Estimation of sleep problems among pregnant women during COVID-19 pandemic: a systematic review and meta-analysis

OBJECTIVE

To estimate the sleep problems among pregnant women during the COVID-19 pandemic.

ELIGIBILITY CRITERIA

English, peer-reviewed, observational studies published between December 2019 and July 2021 which assessed and reported sleep problem prevalence using a valid and reliable measure were included.

INFORMATION SOURCES

Scopus, Medline/PubMed Central, ProQuest, ISI Web of Knowledge and Embase.

RISK OF BIAS ASSESSMENT TOOL

The Newcastle-Ottawa Scale checklist.

SYNTHESIS OF RESULTS

Prevalence of sleep problems was synthesised using STATA software V.14 using a random effects model. To assess moderator analysis, meta-regression was carried out. Funnel plot and Egger's test were used to assess publication bias. Meta-trim was used to correct probable publication bias. The jackknife method was used for sensitivity analysis.

INCLUDED STUDIES

A total of seven cross-sectional studies with 2808 participants from four countries were included.

SYNTHESIS OF RESULTS

The pooled estimated prevalence of sleep problems was 56% (95% CI 23% to 88%, I²=99.81%, Tau²=0.19). Due to the probability of publication bias, the fill-and-trim method was used to correct the estimated pooled measure, which imputed four studies. The corrected results based on this method showed that pooled prevalence of sleep problems was 13% (95% CI 0% to 45%; p<0.001). Based on meta-regression, age was the only significant predictor of prevalence of sleep problems among pregnant women.

LIMITATIONS OF EVIDENCE

All studies were cross-sectional absence of assessment of sleep problems prior to COVID-19, and the outcomes of the pregnancies among those with and without sleep problems in a consistent manner are among the limitation of the current review.

INTERPRETATION

Pregnant women have experienced significant declines in sleep quality when faced with the COVID-19 pandemic. The short-term and long-term implications of such alterations in sleep on gestational and offspring outcomes are unclear and warrant further studies.

Understanding maternal postnatal blood pressure changes following hypertensive disorders in pregnancy: protocol for a prospective cohort study

INTRODUCTION

Hypertensive disorders occur in approximately 10% of women during pregnancy. There is robust population-based data to show that women who have hypertension in pregnancy are much more likely to develop cardiovascular disease (CVD) in the postpartum period. Women with a hypertensive disorder of pregnancy (HDP) are twice more at risk of heart disease and stroke, and four times more likely to develop hypertension after birth. Two out of three women who had HDP will die from CVD. Recent evidence suggests that young women with HDP develop signs of CVD in the immediate postpartum period, rather than several decades later as previously presumed. If confirmed, this concerning finding presents healthcare practitioners with an opportunity to influence women's cardiovascular health by advising on lifestyle choices and considering therapeutic interventions to prevent the development of CVD.

METHODS AND ANALYSIS

This prospective cohort study design will ask approximately 300 participants to complete 3 days of home blood pressure monitoring every fortnight for 12 weeks postpartum and will culminate with a 24-hour episode of ambulatory blood pressure monitoring at 12 weeks postpartum. Women and healthcare professionals will complete questionnaires surrounding postpartum care for women who had HDP and knowledge of CVD risk. In addition, the relationship between hypertension and factors likely to influence outcomes such as severity of HDP, maternal age, body mass index and ethnicity will be analysed using logistic regression. Blood pressure and data from questionnaires will be analysed using descriptive statistics, with temporal stratification.

ETHICS AND DISSEMINATION

Research ethics approval was obtained from London-West London & GTAC Research Ethics Committee. Research outputs will be published and disseminated through midwifery, obstetric or general practitioner targeted academic journals. The patient and public involvement group will disseminate findings to women who have experienced HDP among their peer groups.

Protocol for the IMPART study: IMplementation of the preterm birth surveillance PAthway - a RealisT evaluation

INTRODUCTION

New guidance, from NHS England (Saving Babies Lives Care Bundle Version 2 Element 5 (SBLCBv2)) has recommended a best practice pathway for women at risk of preterm birth (the Preterm Birth Pathway). This is to help meet the Department of Health's aim to reduce preterm birth from 8% to 6% by 2025. Considering most hospitals do not currently have a preterm prevention clinic, implementing this pathway will require significant coordination.

METHODS AND ANALYSIS

The study will aim to investigate key features of contexts, mechanisms and outcomes, and their interactions in the implementation of the asymptomatic prediction and prevention components of the SBLCBv2 Preterm Birth Surveillance Pathway. This will be through a theory driven realist evaluation, utilising mixed methods (interviews with staff and women, observational analysis and analysing routinely collected hospital and admin data) in three case sites in England. The study has a Project Advisory Group composed of five women who have recently given birth.

ETHICS AND DISSEMINATION

The study has ethical approval (King's College London REC approval number: MRSP-20/21-20955, and, IRAS:289144). A dissemination plan will be fully created with the Project Advisory Group, and we anticipate this will include presenting at conferences, publications, webinars, alongside dissemination to the wider population through parent and baby groups, the media and charities.

Rural-urban correlates of skilled birth attendance utilisation in Sierra Leone: evidence from the 2019 Sierra Leone Demographic Health Survey

OBJECTIVES

Understanding the rural-urban context-specific correlates of skilled birth attendance (SBA) is important to designing relevant strategies and programmes. This analysis aimed to assess for the rural-urban correlates of SBA in Sierra Leone.

SETTING

The latest nationally representative Sierra Leone Demographic and Health Survey of 2019.

PARTICIPANTS

The study included a weighted sample of 7326 women aged 15-49 years. Each of them had a live birth within 5 years prior to the survey (4531 in rural areas and 2795 women in urban areas).

PRIMARY AND SECONDARY OUTCOME MEASURE

SBA (primary) and predictors of SBA (secondary).

RESULTS

SBA was higher in urban areas at 94.9% (95% CI 94.1% to 95.7%) compared with 84.2% (95% CI 83.8% to 85.9%) in rural areas. Rural women resident in the Southern, Northern and Eastern regions, with postprimary education (adjusted OR (aOR) 1.8; 95% CI 1.3 to 2.5), exposure to mass media (aOR 1.5; 95% CI 1.1 to 1.9), not having difficulties with distance to the nearest health facility (aOR 2.3; 95% CI 1.7 to 3.0) were associated with higher odds of SBA. Urban women resident in the Southern, Eastern region, with households having less than seven members (aOR 1.5; 95% CI 1.1 to 2.3), exposure to mass media (aOR 1.8; 95% CI 1.1 to 2.9) and not having difficulties with distance to the nearest health facility (aOR 1.6; 95% CI 1.1 to 2.5) were associated with higher odds of SBA.

CONCLUSION

Given the observed differences, improving SBA requires programmes and strategies that are context-specific.

Feasibility of establishing a Canadian Obstetric Survey System (CanOSS) for severe maternal morbidity: a study protocol

INTRODUCTION

Severe maternal morbidity (SMM)-an unexpected pregnancy-associated maternal outcome resulting in severe illness, prolonged hospitalisation or long-term disability-is recognised by many, as the preferred indicator of the quality of maternity care, especially in high-income countries. Obtaining comprehensive details on events and circumstances leading to SMM, obtained through maternity units, could complement data from large epidemiological studies and enable targeted interventions to improve maternal health. The aim of this study is to assess the feasibility of gathering such data from maternity units across Canadian provinces and territories, with the goal of establishing a national obstetric survey system for SMM in Canada.

METHODS AND ANALYSIS

We propose a sequential explanatory mixed-methods study. We will first distribute a cross-sectional survey to leads of all maternity units across Canada to gather information on (1) Whether the unit has a system for reviewing SMM and the nature and format of this system, (2) Willingness to share anonymised data on SMM by direct entry using a web-based platform and (3) Respondents' perception on the definition and leading causes of SMM at a local level. This will be followed by semistructured interviews with respondent groups defined a priori, to identify barriers and facilitators for data sharing. We will perform an integrated analysis to determine feasibility outcomes, a narrative description of barriers and facilitators for data-sharing and resource implications for data acquisition on an annual basis, and variations in top-5 causes of SMM.

ETHICS AND DISSEMINATION

The study has been approved by the Mount Sinai and Hamilton Integrated Research Ethics Boards. The study findings will be presented at annual scientific meetings of the Society of Obstetricians and Gynaecologists of Canada, North American Society of Obstetric Medicine, and International Network of Obstetric Survey Systems and published in an open-access peer-reviewed Obstetrics and Gynaecology or General Internal Medicine journal.

Late pregnancy ultrasound parameters identifying fetuses at risk of adverse perinatal outcomes: a protocol for a systematic review of systematic reviews

INTRODUCTION

Stillbirths and neonatal deaths are leading contributors to the global burden of disease and pregnancy ultrasound has the potential to help decrease this burden. In the absence of high-Grading of Recommendations Assessment, Development and Evaluation (GRADE) evidence on universal obstetric ultrasound screening at or close to term, many different screening strategies have been proposed. Systematic reviews have rapidly increased over the past decade owing to the diverse nature of ultrasound parameters and the wide range of possible adverse perinatal outcomes. This systematic review will summarise the evidence on key ultrasound parameters in the published literature to help develop an obstetric ultrasound protocol that identifies pregnancies at risk of adverse perinatal outcomes at or close to term.

METHODS

This study will follow the recent Cochrane guidelines for a systematic review of systematic reviews. A comprehensive literature search will be conducted using Embase (OvidSP), Medline (OvidSP), CDSR, CINAHL (EBSCOhost) and Scopus. Systematic reviews evaluating at least one ultrasound parameter in late pregnancy to detect pregnancies at risk of adverse perinatal outcomes will be included. Two independent reviewers will screen, assess the quality including the risk of bias using the ROBIS tool, and extract data from eligible systematic reviews that meet the study inclusion criteria. Overlapping data will be assessed and managed with decision rules, and study evidence including the GRADE assessment of the certainty of results will be presented as a narrative synthesis as described in the Cochrane guidelines for an overview of reviews.

ETHICS AND DISSEMINATION

This research uses publicly available published data; thus, an ethics committee review is not required. The findings will be published in a peer-reviewed journal.

Study protocol to quantify the genetic architecture of sonographic cervical length and its relationship to spontaneous preterm birth

INTRODUCTION

A short cervix (cervical length <25 mm) in the midtrimester (18-24 weeks) of pregnancy is a powerful predictor of spontaneous preterm delivery. Although the biological mechanisms of cervical change during pregnancy have been the subject of extensive investigation, little is known about whether genes influence the length of the cervix, or the extent to which genetic factors contribute to premature cervical shortening. Defining the genetic architecture of cervical length is foundational to understanding the aetiology of a short cervix and its contribution to an increased risk of spontaneous preterm delivery.

METHODS/ANALYSIS

The proposed study is designed to characterise the genetic architecture of cervical length and its genetic relationship to gestational age at delivery in a large cohort of Black/African American women, who are at an increased risk of developing a short cervix and delivering preterm. Repeated measurements of cervical length will be modelled as a longitudinal growth curve, with parameters estimating the initial length of the cervix at the beginning of pregnancy, and its rate of change over time. Genome-wide complex trait analysis methods will be used to estimate the heritability of cervical length growth parameters and their bivariate genetic correlation with gestational age at delivery. Polygenic risk profiling will assess maternal genetic risk for developing a short cervix and subsequently delivering preterm and evaluate the role of cervical length in mediating the relationship between maternal genetic variation and gestational age at delivery.

ETHICS/DISSEMINATION

The proposed analyses will be conducted using deidentified data from participants in an IRB-approved study of longitudinal cervical length who provided blood samples and written informed consent for their use in future genetic research. These analyses are preregistered with the Center for Open Science using the AsPredicted format and the results and genomic summary statistics will be published in a peer-reviewed journal.

Qualitative research on maternal care access among Arabic-speaking refugee women in the USA: study protocol

BACKGROUND

Refugees tend to have greater health needs and pre-existing medical conditions due to poor living conditions, lack of health services, exposure to a variety of risk factors, and a high level of stress and trauma prior to entry to a host country. Notwithstanding distinctive needs and inherent conditions, there is a paucity of literature on refugee maternal health, especially for Arabic-speaking refugee women resettled in the USA.

METHODS AND ANALYSIS

The paper delineates a qualitative study protocol to explore the experiences of Arabic-speaking refugee women in the USA when accessing maternal care. Informed by social cognitive theory, the study will employ two qualitative research methods; in-depth interviews and 'go-along' interviews with Arabic-speaking refugee women. Go-along interview will be used to elicit spatial experiences in situ to explore perceptions of environments among study participants and environmental and structural barriers. 20 refugee women who meet the inclusion criteria will be recruited through snowball sampling with support from community partners. Two researchers will code the transcription and fieldnotes using MAXQDA 2020 (VERBI Software, 2019). The analysis will involve deductive content analysis using a structured categorisation matrix based on the theory while also incorporating inductive codes that may emerge through the process.

ETHICS AND DISSEMINATION

The study has been reviewed and approved by the Human Subjects Protection Programme at the University of Arizona (IRB 2104716241). The study results will be condensed in a summary report, which will be shared with community partners, including refugee resettlement agencies and relevant staff at the state department. Also, community feedback will be garnered from the dissemination workshops to inform community discussions for actions and an intervention to address the identified needs.

Development of type 2 diabetes in women with comorbid gestational diabetes and common mental disorders in the Born in Bradford cohort

OBJECTIVES

To compare, in a population of women with gestational diabetes mellitus (GDM), the time to diagnosis of Type 2 diabetes in those with and without common mental disorder (CMD) (depression and/or anxiety) during pregnancy.

DESIGN AND SETTING

prospective study of the Born in Bradford cohort in Bradford, UK.

PARTICIPANTS

909 women diagnosed with GDM between 2007 and 2010, with linkage to their primary care records until 2017. The exposed population were women with an indicator of CMD during pregnancy in primary care records. The unexposed were those without an indicator.

OUTCOME MEASURES

Time to diagnosis of type 2 diabetes as indicated by a diagnosis in primary care records.

ANALYSIS

time to event analysis using Cox regression was employed. Multiple imputation by chained equations was implemented to handle missing data. Models were adjusted for maternal age, ethnicity, education, preconception CMD and tobacco smoking during pregnancy.

RESULTS

165 women (18%) were diagnosed with type 2 diabetes over a follow-up period of around 10 years. There was no evidence of an effect of antenatal CMD on the development of type 2 diabetes following GDM (adjusted HR 0.95; 95% CI 0.57 to 1.57).

CONCLUSIONS

Women with CMD were not at an increased risk of type 2 diabetes following GDM. This is reassuring for women with these co-morbidities but requires replication in other study populations.

Over-the-counter provision of emergency contraceptive pills: a systematic review

OBJECTIVE

To synthesise evidence around over-the-counter (OTC) emergency contraceptive pills (ECPs) to expand the evidence base on self-care interventions.

DESIGN

Systematic review (PROSPERO# CRD42021231625).

ELIGIBILITY CRITERIA

We included publications comparing OTC or pharmacy-access ECP with prescription-only ECPs and measuring ECP uptake, correct use, unintended pregnancy, abortion, sexual practices/behaviour, self-efficacy and side-effects/harms. We also reviewed studies assessing values/preferences and costs of OTC ECPs.

DATA SOURCES

We searched PubMed, CINAL, LILACS, EMBASE, clinicaltrials.gov, WHO International Clinical Trials Registry Platform, Pan African Clinical Trials Registry, Australian New Zealand Clinical Trials Registry, Cochrane Fertility Regulation and International Consortium for Emergency Contraception through 2 December 2020.

RISK OF BIAS

For trials, we used Cochrane Collaboration's tool for assessing risk of bias; for other studies, we used the Evidence Project risk of bias tool.

DATA EXTRACTION AND SYNTHESIS

We summarised data in duplicate using Grading of Recommendations Assessment, Development and Evaluation (GRADE) Evidence Profile tables, reporting findings by study design and outcome. We qualitatively synthesised values/preferences and cost data.

RESULTS

We included 19 studies evaluating effectiveness of OTC ECP, 56 on values/preferences and 3 on costs. All studies except one were from high-income and middle-income settings. Broadly, there were no differences in overall ECP use, pregnancy or sexual behaviour, but an increase in timely ECP use, when comparing OTC or pharmacy ECP to prescription-only ECP groups. Studies showed similar/lower abortion rates in areas with pharmacy availability of ECPs. Users and providers generally supported OTC ECPs; decisions for use were influenced by privacy/confidentiality, convenience, and cost. Three modelling studies found pharmacy-access ECPs would lower health sector costs.

CONCLUSION

OTC ECPs are feasible and acceptable. They may increase access to and timely use of effective contraception. Existing evidence suggests OTC ECPs do not substantively change reproductive health outcomes. Future studies should examine OTC ECP's impacts on user costs, among key subgroups and in low-resource settings.

Myo-inositol nutritional supplement for prevention of gestational diabetes (EMmY): a randomised, placebo-controlled, double-blind pilot trial with nested qualitative study

OBJECTIVES

To determine the feasibility and acceptability of conducting a randomised trial on the effects of myo-inositol in preventing gestational diabetes in high-risk pregnant women.

DESIGN

A multicentre, double-blind, placebo-controlled, pilot randomised trial with nested qualitative evaluation.

SETTING

Five inner city UK National Health Service hospitals PARTICIPANTS: Multiethnic pregnant women at 12⁺⁰ and 15⁺⁶ weeks' gestation with risk factors for gestational diabetes.

INTERVENTIONS

2 g of myo-inositol or placebo, both included 200 µg folic acid, twice daily until delivery.

PRIMARY OUTCOME MEASURES

Rates of recruitment, randomisation, adherence and follow-up.

SECONDARY OUTCOME MEASURES

Glycaemic indices (including homoeostatic model assessment-insulin resistance HOMA-IR), gestational diabetes (diagnosed using oral glucose tolerance test at 28 weeks and by delivery), maternal, perinatal outcomes, acceptability of intervention and costs.

RESULTS

Of the 1326 women screened, 58% (773/1326) were potentially eligible, and 27% (205/773) were recruited. We randomised 97% (198/205) of all recruited women (99 each in intervention and placebo arms) and ascertained outcomes in 90% of women (178/198) by delivery. The mean adherence was 52% (SD 44) at 28 weeks' and 34% (SD 41) at 36 weeks' gestation. HOMA-IR and serum insulin levels were lower in the myo-inositol vs placebo arm (mean difference -0.6, 95% CI -1.2 to 0.0 and -2.69, 95% CI -5.26 to -0.18, respectively). The study procedures were acceptable to women and healthcare professionals. Women who perceived themselves at high risk of gestational diabetes were more likely to participate and adhere to the intervention. The powder form of myo-inositol and placebo, along with nausea in pregnancy were key barriers to adherence.

CONCLUSIONS

A future trial on myo-inositol versus placebo to prevent gestational diabetes is feasible. The intervention will need to be delivered in a non-powder form to improve adherence. There is a signal for efficacy in reducing insulin resistance in pregnancy with myo-inositol.

Assessing the reliability of phone surveys to measure reproductive, maternal and child health knowledge among pregnant women in rural India: a feasibility study

OBJECTIVES

Efforts to understand the factors influencing the uptake of reproductive, maternal, newborn, child health and nutrition (RMNCH&N) services in high disease burden low-resource settings have often focused on face-to-face surveys or direct observations of service delivery. Increasing access to mobile phones has led to growing interest in phone surveys as a rapid, low-cost alternatives to face-to-face surveys. We assess determinants of RMNCH&N knowledge among pregnant women with access to phones and examine the reliability of alternative modalities of survey delivery.

PARTICIPANTS

Women 5-7 months pregnant with access to a phone.

SETTING

Four districts of Madhya Pradesh, India.

DESIGN

Cross-sectional surveys administered face-to-face and within 2 weeks, the same surveys were repeated among two random subsamples of the original sample: face-to-face (n=205) and caller-attended telephone interviews (n=375). Bivariate analyses, multivariable linear regression, and prevalence and bias-adjusted kappa scores are presented.

RESULTS

Knowledge scores were low across domains: 52% for maternal nutrition and pregnancy danger signs, 58% for family planning, 47% for essential newborn care, 56% infant and young child feeding, and 58% for infant and young child care. Higher knowledge (≥1 composite score) was associated with older age; higher levels of education and literacy; living in a nuclear family; primary health decision-making; greater attendance in antenatal care and satisfaction with accredited social health activist services. Survey questions had low inter-rater and intermodal reliability (kappa<0.70) with a few exceptions. Questions with the lowest reliability included true/false questions and those with unprompted, multiple response options. Reliability may have been hampered by the sensitivity of the content, lack of privacy, enumerators' and respondents' profile differences, rapport, social desirability bias, and/or enumerator's ability to adequately convey concepts or probe.

CONCLUSIONS

Phone surveys are a reliable modality for generating population-level estimates data about pregnant women's knowledge, however, should not be used for individual-level tracking.

Medical expenditure of women during pregnancy, childbirth and puerperium at the beginning of China's universal two-child policy enactment: a population-based retrospective study

OBJECTIVES

To describe and explore women's medical expenditures during pregnancy, childbirth and puerperium at the beginning of the universal two-child policy enactment in China.

DESIGN

Population-based retrospective study.

SETTING

Dalian, China.

PARTICIPANTS

Under the System of Health Accounts 2011 framework, the macroscopic dataset was obtained from the annual report at the provincial and municipal levels in China. The research sample incorporated 65 535 inpatient and outpatient records matching International Classification of Diseases, 10th Revision codes O00-O99 in Dalian city from 2015 through 2017.

PRIMARY AND SECONDARY OUTCOME MEASURES

The study delineates women's current curative expenditure (CCE) during pregnancy, childbirth and puerperium at the beginning of the universal two-child policy in China. The temporal changes of medical expenditure of women during pregnancy, childbirth and puerperium at the beginning of China's universal two-child policy enactment were assessed. The generalised linear model and structural equation model were used to test the association between medical expenditure and study variables.

RESULTS

Unlike the inverted V-shaped trend in the number of live newborns in Dalian over the 3 studied years, CCE on pregnancy, childbirth and puerperium dipped slightly in 2016 (¥260.29 million) from 2015 (¥263.28 million) and saw a surge in 2017 (¥288.65 million). The ratio of out-of-pocket payment/CCE reduced year by year. There was a rapid increase in CCE in women older than 35 years since 2016. Length of stay mediated the relationship between hospital level, year, age, reimbursement ratio and medical expenditure.

CONCLUSIONS

The rise in CCE on pregnancy, delivery and puerperium lagged 1 year behind the surge of newborns at the beginning of China's universal two-child policy. Length of stay acted as a crucial mediator driving up maternal medical expenditure. Reducing medical expenditure by shortening the length of stay could be a feasible way to effectively address the issue of cost in women during pregnancy, childbirth and puerperium.

Intended versus actual delivery location and factors associated with change in delivery location among pregnant women in Southern Province, Zambia: a prespecified secondary observational analysis of the ZamCAT

OBJECTIVES

This prespecified, secondary analysis of the Zambia Chlorhexidine Application Trial (ZamCAT) aimed to determine the proportion of women who did not deliver where they intended, to understand the underlying reasons for the discordance between planned and actual delivery locations; and to assess sociodemographic characteristics associated with concordance of intention and practice.

DESIGN

Prespecified, secondary analysis from randomised controlled trial.

SETTING

Recruitment occurred in 90 primary health facilities (HFs) with follow-up in the community in Southern Province, Zambia.

PARTICIPANTS

Between 15 February 2011 and 30 January 2013, 39 679 pregnant women enrolled in ZamCAT.

SECONDARY OUTCOME MEASURES

The location where mothers gave birth (home vs HF) was compared with their planned delivery location.

RESULTS

When interviewed antepartum, 92% of respondents intended to deliver at an HF, 6.1% at home and 1.2% had no plan. However, of those who intended to deliver at an HF, 61% did; of those who intended to deliver at home, only 4% did; and of those who intended to deliver at home, 2% delivered instead at an HF. Among women who delivered at home, women who were aged 25-34 and ≥35 years were more likely to deliver where they intended than women aged 20-24 years (adjusted OR (aOR)=1.31, 95% CI=1.11 to 1.50 and aOR=1.32, 95% CI=1.12 to 1.57, respectively). Women who delivered at HFs had greater odds of delivering where they intended if they received any primary schooling (aOR=1.34, 95% CI=1.09 to 1.72) or more than a primary school education (aOR=1.54, 95% CI=1.17 to 2.02), were literate (aOR=1.33, 95% CI=1.119 to 1.58), and were not in the lowest quintile of the wealth index.

CONCLUSION

Discrepancies between intended and actual delivery locations highlight the need to go beyond the development of birth plans and exposure to birth planning messaging. More research is required to address barriers to achieving intentions of a facility-based childbirth.

Using machine learning to identify quality-of-care predictors for emergency caesarean sections: a retrospective cohort study

OBJECTIVES

Emergency caesarean sections (ECS) are time-sensitive procedures. Multiple factors may affect team efficiency but their relative importance remains unknown. This study aimed to identify the most important predictors contributing to quality of care during ECS in terms of the arrival-to-delivery interval.

DESIGN

A retrospective cohort study. ECS were classified by urgency using emergency categories one/two and three (delivery within 30 and 60 min). In total, 92 predictor variables were included in the analysis and grouped as follows: 'Maternal objective', 'Maternal psychological', 'Fetal factors', 'ECS Indication', 'Emergency category', 'Type of anaesthesia', 'Team member qualifications and experience' and 'Procedural'. Data was analysed with a linear regression model using elastic net regularisation and jackknife technique to improve generalisability. The relative influence of the predictors, percentage significant predictor weight (PSPW) was calculated for each predictor to visualise the main determinants of arrival-to-delivery interval.

SETTING AND PARTICIPANTS

Patient records for mothers undergoing ECS between 2010 and 2017, Nordsjællands Hospital, Capital Region of Denmark.

PRIMARY OUTCOME MEASURES

Arrival-to-delivery interval during ECS.

RESULTS

Data was obtained from 2409 patient records for women undergoing ECS. The group of predictors representing 'Team member qualifications and experience' was the most important predictor of arrival-to-delivery interval in all ECS emergency categories (PSPW 25.9% for ECS category one/two; PSPW 35.5% for ECS category three). In ECS category one/two the 'Indication for ECS' was the second most important predictor group (PSPW 24.9%). In ECS category three, the second most important predictor group was 'Maternal objective predictors' (PSPW 24.2%).

CONCLUSION

This study provides empirical evidence for the importance of team member qualifications and experience relative to other predictors of arrival-to-delivery during ECS. Machine learning provides a promising method for expanding our current knowledge about the relative importance of different factors in predicting outcomes of complex obstetric events.

Use of and barriers to maternal health services in southeast Chad: results of a population-based survey 2019

OBJECTIVES

Chad reports the second highest maternal mortality worldwide. We conducted a survey in Sila region in southeast Chad to estimate the use of maternal health services (MHS) and to identify barriers to access MHS.

DESIGN

Retrospective cross-sectional, population-based survey using two-stage cluster sampling methodology. The survey consisted of two strata, Koukou Angarana and Goz Beida district in Sila region. We conducted systematic random sampling proportional to population size to select settlements in each strata in the first sampling stage; and in the second stage we selected households in the settlements using random walk procedure. We calculated survey-design-weighted proportions with 95% CIs. We performed univariate analysis and multivariable logistic regression to identify impact factors associated with the use of MHS.

SETTING

We interviewed women in selected households in Sila region in 2019.

PARTICIPANTS

Women at reproductive age, who have given birth in the previous 2 years and are living in Koukou Angarana and Goz Beida district.

PRIMARY OUTCOMES

Use of and access barriers to MHS including antenatal care (ANC), delivery care in a health facility (DC), postnatal care (PNC) and contraceptive methods.

RESULTS

In total, 624 women participated. Median age was 28 years, 95.4% were illiterate and 95.7% married. Use of ANC, DC and PNC was reported by 57.6% (95% CI: 49.3% to 65.5%), 22.5% (95% CI: 15.7% to 31.1%) and 32.9% (95% CI: 25.8% to 40.9%), respectively. Use of MHS was lower in rural compared with urban settings. Having attended ANC increased the odds of using DC by 4.3 (1.5-12.2) and using PNC by 6.4 (3.7-11.1). Factors related to transport and to culture and belief were the most frequently stated access barriers to MHS.

CONCLUSION

In Sila region, use of MHS is low and does not meet WHO-defined standards regarding maternal health. Among all services, use of ANC was better than for other MHS. ANC usage is positively associated with the use of further life-saving MHS including DC and could be used as an entry point to the community. To increase use of MHS, interventions should include infrastructural improvements as well as community-based approaches to overcome access barriers related to culture and belief.

Patient journey during and after a pre-eclampsia-complicated pregnancy: a cross-sectional patient registry study

OBJECTIVES

To gain insight into the patient journey through a pre-eclampsia-complicated pregnancy.

DESIGN

Cross-sectional patient registry study.

SETTING

Online patient registry initiated by the Preeclampsia Foundation.

PARTICIPANTS

Women with a history of pre-eclampsia enrolled in The Preeclampsia Registry (TPR).

PRIMARY AND SECONDARY OUTCOME MEASURES

Retrospective patient-reported experience measures concerning awareness of pre-eclampsia, timing and type of information on pre-eclampsia received, involvement in decision making regarding medical care, mental/emotional impact of the pre-eclampsia-complicated pregnancy and impact on future pregnancy planning.

RESULTS

Of 3618 TPR-participants invited to complete the Patient Journey questionnaire, data from 833 (23%) responders were available for analysis. Most responders were white (n=795, 95.4%) and lived in the USA (n=728, 87.4%). Before their pre-eclampsia diagnosis, 599 (73.9%) responders were aware of the term 'pre-eclampsia', but only 348 (43.7%) were aware of its associated symptoms. Women with a lower level of education were less likely to have heard of pre-eclampsia (OR 0.36, 95% CI 0.21 to 0.62). Around the time of diagnosis, 29.2% of responders did not feel involved in the decision making, which was associated with reporting a serious mental/emotional impact of the pre-eclampsia experience (OR 2.46, 95% CI 1.58 to 3.84). Over time, there was an increase in the proportion of women who were aware of the symptoms of pre-eclampsia (32.2% before 2011 to 52.5% after 2016; p<0.001) and in the proportion of responders stating they received counselling about the later-life health risks associated with pre-eclampsia (14.2% before 2011 to 25.6% after 2016; p=0.005).

CONCLUSIONS

This study demonstrates that improved patient education regarding pre-eclampsia is needed, that shared decision making is of great importance to patients to enhance their healthcare experience, and that healthcare providers should make efforts to routinely incorporate counselling about the later-life health risks associated with pre-eclampsia.

Predictors of adverse perinatal outcome among women who gave birth at Medical Center of Southwest Ethiopia: a retrospective cohort study

OBJECTIVES

The aim of this study was to determine predictors of adverse perinatal outcome among women who gave birth at Medical Center of Southwest Ethiopia.

SETTING

Institutional based retrospective cohort study was conducted among women who gave birth at Medical Center of Southwest Ethiopia.

PARTICIPANTS

Medical record of 777 women was included in the study by using maternity HMIS logbook as entry point. Simple random sampling technique without replacement was employed to select individual medical record using computer generated random numbers.

PRIMARY OUTCOME MEASURED

Predictors of adverse perinatal outcome were examined using modified Poisson regression with a robust SE.

RESULTS

Majority, 74.1% of the participants were in the age group of 21-34 years and the median age was 26 (IQR=7) years. More than one-third, 35.9% of the mothers were primigravida and only 21.2% of them had above four antenatal cares (ANC) visit. The overall incidence of adverse perinatal outcome was 31.5% (95% CI: 28.3 to 34.9). Maternal age less than 20 years (adjusted risk ratio, aRR=1.3; 95% CI: 1.01 to 1.5), rural residence (aRR=1.27; 95% CI: 1.04 to 1.59), presence of antepartum haemorrhage in current pregnancy (aRR=1.7; 95% CI: 1.38 to 2.07), maternal anaemia (aRR=1.25; 95% CI: 1.03 to 1.53), lack of ANC visit (aRR=2.29; 95% CI: 1.35 to 3.90), induced labour (aRR=1.77; 95% CI: 1.43 to 2.19) and being positive for venereal disease research laboratory (VDRL) test in current pregnancy (aRR=2.0; 95% CI: 1.16 to 3.38) were found to be significantly associated with adverse perinatal outcome.

CONCLUSION

The incidence of adverse perinatal outcome in the study area is high and maternal age less than 20, rural residency, maternal anaemia, antepartum haemorrhage in the current pregnancy, inadequate ANC visit, induction of labour and being positive for VDRL test were found to predict occurrence of adverse perinatal outcome. Majority of these problems can be managed by providing quality antenatal, intrapartum and post-natal care.

Psychological well-being of women at high risk of spontaneous preterm birth cared for in a specialised preterm birth clinic: a prospective longitudinal cohort study

OBJECTIVES

To assess the psychological well-being of pregnant women at increased risk of spontaneous preterm birth, and the impact of care from a preterm birth clinic.

DESIGN

Single-centre longitudinal cohort study over 1 year, 2018-2019.

SETTING

Tertiary maternity hospital in Auckland, New Zealand.

PARTICIPANTS

Pregnant women at increased risk of spontaneous preterm birth receiving care in a preterm birth clinic.

INTERVENTION

Participants completed three sets of questionnaires (State-Trait Anxiety Inventory, Edinburgh Postnatal Depression Scale, and 36-Item Short Form Survey)-prior to their first, after their second, and after their last clinic appointments. Study-specific questionnaires explored pregnancy-related anxiety and perceptions of care.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome was the mean State-Anxiety score. Secondary outcomes included depression and quality of life measures.

RESULTS

73/97 (75.3%) eligible women participated; 41.1% had a previous preterm birth, 31.5% a second trimester loss and 28.8% cervical surgery; 20.6% had a prior mental health condition. 63/73 (86.3%) women completed all questionnaires. The adjusted mean state-anxiety score was 39.0 at baseline, which decreased to 36.5 after the second visit (difference -2.5, 95% CI -5.5 to 0.5, p=0.1) and to 32.6 after the last visit (difference -3.9 from second visit, 95% CI -6.4 to -1.5, p=0.002). Rates of anxiety (state-anxiety score >40) and depression (Edinburgh Postnatal Depression Scale score >12) were 38.4%, 34.8%, 19.0% and 13.7%, 8.7%, 9.5% respectively, at the same time periods. Perceptions of care were favourable; 88.9% stated the preterm birth clinic made them significantly or somewhat less anxious and 87.3% wanted to be seen again in a future pregnancy.

CONCLUSIONS

Women at increased risk of spontaneous preterm birth have high levels of anxiety. Psychological well-being improved during the second trimester; women perceived that preterm birth clinic care reduced pregnancy-related anxiety. These findings support the ongoing use and development of preterm birth clinics.

Self-testing for pregnancy: a systematic review and meta-analysis

OBJECTIVES

Urine pregnancy tests are often inaccessible in low-income settings. Expanded provision of home pregnancy testing could support self-care options for sexual and reproductive health and rights. We conducted a systematic review of pregnancy self-testing effectiveness, values and preferences and cost.

DESIGN

Systematic review and meta-analysis using the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) approach.

DATA SOURCES

PubMed, CINAHL, LILACS and EMBASE and four trial registries were searched through 2 November 2020.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included trials and observational studies that compared urine self-testing for pregnancy to health worker-led pregnancy testing on effectiveness outcomes; quantitative and qualitative studies describing values and preferences of end users and health workers and costs of pregnancy self-testing.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers used standardised methods to search, screen and code included studies. Risk of bias was assessed using the Cochrane Collaboration and Evidence Project tools. Meta-analysis was conducted using random effects models. Findings were summarised in GRADE evidence profiles and synthesised qualitatively.

RESULTS

For effectiveness, four randomised trials following 5493 individuals after medical abortion showed no difference or improvements in loss to follow-up with home pregnancy self-testing compared with return clinic visits. One additional trial of community health workers offering home pregnancy tests showed a significant increase in pregnancy knowledge and antenatal counselling among 506 clients. Eighteen diverse values and preferences studies found support for pregnancy self-testing because of quick results, convenience, confidentiality/privacy, cost and accuracy. Most individuals receiving pregnancy self-tests for postabortion home management preferred this option. No studies reported cost data.

CONCLUSION

Pregnancy self-testing is acceptable and valued by end users. Effectiveness data come mostly from articles on postabortion care, and cost data are lacking. Greater availability of pregnancy self-tests, including in postabortion care and CHW programs, may lead to improved health outcomes.

Utilisation of immediate postpartum family planning among postpartum women at public hospitals of North Shoa Zone, Ethiopia: a cross-sectional study

OBJECTIVE

This study aimed to assess the prevalence of immediate postpartum family planning utilisation and the associated factors among postpartum women at public hospitals of North Shoa Zone, Ethiopia.

DESIGN AND METHODS

A facility-based cross-sectional study was conducted in 1-30 May 2020. Systematic random sampling technique was used to select the participants. Data were collected through a face-to-face interview using a structured and pretested questionnaire. Univariate and multivariable logistic regression analyses were employed. In multivariable logistic regression analysis, p<0.05 and adjusted OR (AOR) with 95% CI were used to declare statistically significant factors.

SETTING AND PARTICIPANTS

The study was conducted at public hospitals of North Shoa Zone, Ethiopia. A total of 394 postpartum women within 48 hours after giving birth before discharge from the selected hospitals were enrolled in the study.

OUTCOME

Immediate postpartum family planning utilisation (used or not used).

RESULTS

Of the total 394 participants, 84 (21.3%) used immediate postpartum family planning. The factors associated with immediate postpartum family planning utilisation were women's age (30-34 years) (AOR: 0.118; 95% CI 0.023 to 0.616), planning status of pregnancy (AOR: 3.175; 95% CI 1.063 to 9.484), reproductive intention (AOR: 5.046; 95% CI 1.545 to 16.479), partner support (AOR: 4.293; 95% CI 1.181 to 15.61), attitude towards family planning (AOR: 2.908; 95% CI 1.081 to 7.824) and maternal satisfaction with intrapartum care (AOR: 6.243; 95% CI 2.166 to 17.994).

CONCLUSION

In the study area, only less than a quarter of postpartum women used immediate postpartum family planning. Therefore, enhancing immediate postpartum family planning utilisation, strengthening community awareness to develop a favourable attitude towards family planning, promoting partner involvement in family planning and ensuring maternal satisfaction during intrapartum care are essential.

Postpartum blood pressure self-management following hypertensive pregnancy: protocol of the Physician Optimised Post-partum Hypertension Treatment (POP-HT) trial

INTRODUCTION

New-onset hypertension affects approximately 10% of pregnancies and is associated with a significant increase in risk of cardiovascular disease in later life, with blood pressure measured 6 weeks postpartum predictive of blood pressure 5-10 years later. A pilot trial has demonstrated that improved blood pressure control, achevied via self-management during the puerperium, was associated with lower blood pressure 3-4 years postpartum. Physician Optimised Post-partum Hypertension Treatment (POP-HT) will formally evaluate whether improved blood pressure control in the puerperium results in lower blood pressure at 6 months post partum, and improvements in cardiovascular and cerebrovascular phenotypes.

METHODS AND ANALYSIS

POP-HT is an open-label, parallel arm, randomised controlled trial involving 200 women aged 18 years or over, with a diagnosis of pre-eclampsia or gestational hypertension, and requiring antihypertensive medication at discharge. Women are recruited by open recruitment and direct invitation around time of delivery and randomised 1:1 to, either an intervention comprising physician-optimised self-management of postpartum blood pressure or, usual care. Women in the intervention group upload blood pressure readings to a 'smartphone' app that provides algorithm-driven individualised medication-titration. Medication changes are approved by physicians, who review blood pressure readings remotely. Women in the control arm follow assessment and medication adjustment by their usual healthcare team. The primary outcome is 24-hour average ambulatory diastolic blood pressure at 6-9 months post partum. Secondary outcomes include: additional blood pressure parameters at baseline, week 1 and week 6; multimodal cardiovascular assessments (CMR and echocardiography); parameters derived from multiorgan MRI including brain and kidneys; peripheral macrovascular and microvascular measures; angiogenic profile measures taken from blood samples and levels of endothelial circulating and cellular biomarkers; and objective physical activity monitoring and exercise assessment. An additional 20 women will be recruited after a normotensive pregnancy as a comparator group for endothelial cellular biomarkers.

ETHICS AND DISSEMINATION

IRAS PROJECT ID 273353. This trial has received a favourable opinion from the London-Surrey Research Ethics Committee and HRA (REC Reference 19/LO/1901).

Individual and contextual factors associated with maternal healthcare utilisation in Mali: a cross-sectional study using Demographic and Health Survey data

OBJECTIVE

We examined the national prevalence as well as the individual and contextual factors associated with maternal healthcare utilisation in Mali.

SETTING

The study was conducted in Mali.

PARTICIPANTS

We analysed data on 6335 women aged 15-49 years from Mali's 2018 Demographic and Health Survey.

OUTCOME VARIABLE

Maternal healthcare utilisation comprising antenatal care (ANC) attendant, skilled birth attendant (SBA), and postnatal care (PNC) attendant, was our outcome variable.

RESULTS

Prevalence of maternal healthcare utilisation was 45.6% for ANC4+, 74.7% for SBA and 25.5% for PNC. At the individual level, ANC4 + and SBA utilisation increased with increasing maternal age, level of formal education and wealth status. Higher odds of ANC4 + was found among women who are cohabiting (adjusted OR (aOR)=2.25, 95% CI 1.16 to 4.37) and delivered by caesarean section (aOR=2.53, 95% CI 1.72 to 3.73), while women who considered getting money for treatment (aOR=0.72, 95% CI 0.60 to 0.88) and distance to health facility (aOR=0.73, 95% CI 0.59 to 0.90) as a big problem had lower odds. Odds to use PNC was higher for those who were working (aOR=1.22, 95% CI 1.01 to 1.48) and those covered by health insurance (aOR=1.87, 95% CI 1.36 to 2.57). Lower odds of SBA use were associated with having two (aOR=0.48, 95% CI 0.33 to 0.71), three (aOR=0.37, 95% CI 0.24 to 0.58), and four or more (aOR=0.38, 95% CI 0.24 to 0.59) children, and residing in a rural area (aOR=0.35, 95% CI 0.17 to 1.69). Listening to the radio and watching TV were associated with increased maternal healthcare utilisation.

CONCLUSION

The government should increase availability, affordability and accessibility to healthcare facilities by investing in health infrastructure and workforce to achieve Sustainable Development Goal 3.4 of reducing maternal morality to less than 70 deaths per 100 000 live births by 2030. It is important to ascertain empirically why PNC levels are astonishingly lower relative to ANC and SBA.

Investigating the optimal handling of uncertain pregnancy episodes in the CPRD GOLD Pregnancy Register: a methodological study using UK primary care data

OBJECTIVES

To investigate why episodes of pregnancy identified from electronic health records may be incomplete or conflicting (overlapping), and provide guidance on how to handle them.

SETTING

Pregnancy Register generated from the Clinical Practice Research Datalink (CPRD) GOLD UK primary care database.

PARTICIPANTS

Female patients with at least one pregnancy episode in the Register (01 January 1937-31 December 2017) which had no recorded outcome or conflicted with another episode.

DESIGN

We identified multiple scenarios potentially explaining why uncertain episodes occur. Criteria were established and systematically applied to determine whether episodes had evidence of each scenario. Linked Hospital Episode Statistics were used to identify pregnancy events not captured in primary care.

RESULTS

Of 5.8 million pregnancy episodes in the Register, 932 604 (16%) had no recorded outcome, and 478 341 (8.5%) conflicted with another episode (251 026 distinct conflicting pairs of episodes among 210 593 women). 826 146 (89%) of the episodes without outcome recorded in primary care and 215 577 (86%) of the conflicting pairs were consistent with one or more of our proposed scenarios. For 689 737 (74%) episodes with recorded outcome missing and 215 544 (86%) of the conflicting pairs (at least one episode), supportive evidence (eg, antenatal records, linked hospital records) suggested they were true and current pregnancies. Furthermore, 516 818 (55 %) and 160 936 (64%), respectively, were during research quality follow-up time. For a sizeable proportion of uncertain episode, there is evidence to suggest that historical outcomes being recorded by the general practitioner during an ongoing pregnancy may offer explanation (73 208 (29.2%) and 349 874 (37.5%)).

CONCLUSIONS

This work provides insight to users of the CPRD Pregnancy Register on why uncertain pregnancy episodes exist and indicates that most of these episodes are likely to be real pregnancies. Guidance is given to help researchers consider whether to include/exclude uncertain pregnancies from their studies, and how to tailor approaches to minimise underestimation and bias.
