Approaches to improve and adapt maternal mortality estimations in low- and middle-income countries: A scoping review.

BACKGROUND: In the absence of robust vital registration systems, many low- and middle-income countries (LMICs) rely on national surveys or routine surveillance systems to estimate the maternal mortality ratio (MMR). Although the importance of MMR estimates in ending preventable maternal deaths is acknowledged, there is limited research on how different approaches are used and adapted, and how these adaptations function. OBJECTIVES: To assess methods for estimating maternal mortality in LMICs and the rationale for these modifications. SEARCH STRATEGY: A literature search with the terms "maternal death", "surveys" and "low- and middle-income countries" was performed in Medline, Embase, Web of Science, Scopus, CINAHL, APA PsycINFO, ERIC, and IBSS from January 2013 to March 17, 2023. SELECTION CRITERIA: Studies were eligible if their main focus was to compare, adapt, or assess methods to estimate maternal mortality in LMICs. DATA COLLECTION AND ANALYSIS: Titles and abstracts were screened using Rayyan. Relevant articles were independently reviewed by two reviewers against inclusion criteria. Data were extracted on mortality measurement methods, their context, and results. MAIN RESULTS: Nineteen studies were included, focusing on data completeness, subnational estimates, and community involvement. Routinely generated MMR estimates are more complete when multiple data sources are triangulated, including data from public and private health facilities, the community, and local authorities (e.g. vital registration, police reports). For subnational estimates, existing (e.g. the sisterhood method and reproductive-age mortality surveys [RAMOS]) and adapted methods (e.g. RAMOS 4 + 2 and Pictorial Sisterhood Method) provided reliable confidence intervals. Community engagement in data collection increased community awareness of maternal deaths, provided local ownership, and was expected to reduce implementation costs. However, most studies did not include a cost-effectiveness analysis. CONCLUSION: Household surveys with community involvement and RAMOS can be used to increase data validity, improve local awareness of maternal mortality estimates, and reduce costs in LMICs.

Out of sight, out of mind? Evidence from cross-sectional surveys on hidden caesarean sections among women with stillbirths in Ghana, 2007 and 2017.

BACKGROUND: Caesarean section (CS) rates in women experiencing stillbirth have not been studied with nationally representative data. Two Ghana Maternal Health Surveys (GMHS) have captured pregnancy and mode of birth data for all women including those with stillbirths. We compared CS rates between women with live births and stillbirths, and identified socio-economic and pregnancy-related factors associated with CS in stillbirths. METHODS: A population-based cross-sectional study was conducted in a pooled sample of 17 138 women who had given birth within 5 years preceding the 2007 and 2017 GMHS. CS rates were compared between women with stillbirths and very early neonatal deaths (SBVENDs) and women with live births who survived the first day. Bivariate and multivariable logistic regressions explored variables associated with CS. Effect modification of household's wealth and maternal educational level by birth outcome was assessed using multivariable logistic regression with interaction terms. RESULTS: CS rate in women with SBVEND was 19.3% compared with 9.6% in women with live births who survived the first day (rate ratio 2.2; 95% CI 1.6 to 2.9). In multivariable analysis, attaining middle school compared with no formal education (adjusted OR, aOR 2.8; 95% CI 1.1 to 7.1), having had five or more births compared with nulliparity (aOR 3.7; 95% CI 1.3 to 10.7) and reporting prolonged or obstructed labour (aOR 3.3; 95% CI 1.3 to 8.3) were associated with CS in women with SBVEND. Higher household wealth and educational levels were associated with an increased risk of CS in both study groups, with no statistically significant difference in effect. CONCLUSION: Disaggregating CS rates by birth outcome revealed a high rate among women with SBVEND, twice the overall rate compared with live births. Exclusion of these 'hidden' CSs from rate calculations may lead to underestimation of (inter)national CS rates and potentially conceals CS overuse or misuse.

Pneumomediastinum complicating diabetic ketoacidosis.

Pneumomediastinum is an uncommon finding in patients with diabetic ketoacidosis (DKA) and may occur spontaneously or secondary to an effort rupture of the oesophagus. Excluding oesophageal rupture is important, as delaying treatment increases the risk of mortality. We discuss a case of DKA complicated by vomiting, pneumomediastinum, pneumopericardium and air in the epidural space. Instead of fluoroscopic oesophagography, chest CT was used to investigate oesophageal rupture. We present an overview of case reports and retrospective studies illustrating the utility of chest CT in the investigation of oesophageal rupture over fluoroscopic oesophagography.

Health workers' perspectives on informed consent for caesarean section in Southern Malawi.

OBJECTIVE: Informed consent is a prerequisite for caesarean section, the commonest surgical procedure in low- and middle-income settings, but not always acquired to an appropriate extent. Exploring perceptions of health care workers may aid in improving clinical practice around informed consent. We aim to explore health workers' beliefs and experiences related to principles and practice of informed consent. METHODS: Qualitative study conducted between January and June 2018 in a rural 150-bed mission hospital in Southern Malawi. Clinical observations, semi-structured interviews and a focus group discussion were used to collect data. Participants were 22 clincal officers, nurse-midwives and midwifery students involved in maternity care. Data were analysed to identify themes and construct an analytical framework. RESULTS: Definition and purpose of informed consent revolved around providing information, respecting women's autonomy and achieving legal protection. Due to fear of blame and litigation, health workers preferred written consent. Written consent requires active participation by the consenting individual and was perceived to transfer liability to that person. A woman's refusal to provide written informed consent may pose a dilemma for the health worker between doing good and respecting autonomy. To prevent such refusal, health workers said to only partially disclose surgical risks in order to minimize women's anxiety. Commonly perceived barriers to obtain a fully informed consent were labour pains, language barriers, women's lack of education and their dependency on others to make decisions. CONCLUSIONS: Health workers are familiar with the principles around informed consent and aware of its advantages, but fear of blame and litigation, partial disclosure of risks and barriers to communication hamper the process of obtaining informed consent. Findings can be used to develop interventions to improve the informed consent process.

Pre-post implementation survey of a multicomponent intervention to improve informed consent for caesarean section in Southern Malawi.

OBJECTIVE: Surgical informed consent is essential prior to caesarean section, but potentially compromised by insufficient communication. We assessed the association between a multicomponent intervention and women's recollection of information pertaining to informed consent for caesarean section in a low-resource setting, thereby contributing to respectful maternity care. DESIGN: Pre-post implementation survey, conducted from January to June 2018, surveying women prior to discharge. SETTING: Rural 150-bed mission hospital in Southern Malawi. PARTICIPANTS: A total of 160 postoperative women were included: 80 preimplementation and 80 postimplementation. INTERVENTION: Based on observed deficiencies and input from local stakeholders, a multicomponent intervention was developed, consisting of a standardised checklist, wall poster with a six-step guide and on-the-job communication training for health workers. PRIMARY AND SECONDARY OUTCOME MEASURES: Individual components of informed consent were: indication, explanation of procedure, common complications, implications for future pregnancies and verbal enquiry of consent, which were compared preintervention and postintervention using χ2 test. Generalised linear models were used to analyse incompleteness scores and recollection of the informed consent process. RESULTS: The proportion of women who recollected being informed about procedure-related risks increased from 25/80 to 47/80 (OR 3.13 (95% CI 1.64 to 6.00)). Recollection of an explanation of the procedure changed from 44/80 to 55/80 (OR 1.80 (0.94 to 3.44)), implications for future pregnancy from 25/80 to 47/80 (1.69 (0.89 to 3.20)) and of consent enquiry from 67/80 to 73/80 (OR 2.02 (0.73 to 5.37)). After controlling for other variables, incompleteness scores postintervention were 26% lower (Exp(ß)=0.74; 95% CI 0.57 to 0.96). Recollection of common complications increased with 0.25 complications (ß=0.25; 95% CI 0.01 to 0.49). Recollection of the correct indication did not differ significantly. CONCLUSION: Recollection of informed consent for caesarean section changed significantly in the postintervention group. Obtaining informed consent for caesarean section is one of the essential components of respectful maternity care.
