Methods used to measure maternal mortality in Sub-Saharan Africa from 1980 to 2020: A systematic literature review

Towards a positive postnatal experience in Sub-Saharan African countries: the receipt of adequate services during the immediate postpartum period: a multilevel analysis

Background

Existing studies in the Sub-Saharan African (SSA) region have focused mainly on the frequency of postnatal visits, with little emphasis on the adequacy of care provided during visits. Hence, this study aimed to investigate the magnitude of receiving an adequate number of World Health Organization-recommended contents of care during the immediate postpartum visit, and its predictors in SSA countries.

Methods

The appended women file of the most recent (2016-2021) standardized Demographic and Health Survey report of eighteen Sub-Saharan African countries with a weighted sample of 56,673 women was used for the study. The influence of each predictor on the uptake of adequate postnatal care has been examined using multilevel mixed-effects logistic regression. Significant predictors were reported using the adjusted odds ratio (aOR) with their respective 95% confidence intervals (95% CI).

Results

The pooled prevalence of adequate postnatal care service uptake was found to be 42.94% (95% CI: 34.14, 49.13). Living in the southern sub-region (aOR = 3.08 95% CI: 2.50, 3.80), institutional delivery (aOR = 3.15; 95% CI: 2.90, 3.43), early initiation of ANC (aOR = 1.74; 95% CI: 1.45, 2.09), quality of antenatal care (aOR = 1.59; 95% CI: 1.42, 1.78), Caesarean delivery (aOR = 1.59; 95% CI: 1.42, 1.78), autonomy in decision-making (aOR = 1.30; 95% CI: 1.11, 1.39), high acceptance toward wife beating attitude (aOR = 0.83; 95% CI: 0.73, 0.94), and reading newspapers (aOR = 1.37; 95% CI: 1.21, 1.56) were identified as predictors of receiving adequate postnatal services during the immediate postpartum period.

Conclusion

The findings revealed low coverage of adequate postnatal care service uptake in the region. The Federal Ministry of Health and healthcare managers in each country should coordinate their efforts to develop interventions that promote women's empowerment to enhance their autonomy in decision-making and to reduce attitudes towards wife beating. Healthcare providers ought to strive to provide skilled delivery services and early initiation of antenatal care.

Transfer learning for accurate fetal organ classification from ultrasound images: a potential tool for maternal healthcare providers

Ultrasound imaging is commonly used to aid in fetal development. It has the advantage of being real-time, low-cost, non-invasive, and easy to use. However, fetal organ detection is a challenging task for obstetricians, it depends on several factors, such as the position of the fetus, the habitus of the mother, and the imaging technique. In addition, image interpretation must be performed by a trained healthcare professional who can take into account all relevant clinical factors. Artificial intelligence is playing an increasingly important role in medical imaging and can help solve many of the challenges associated with fetal organ classification. In this paper, we propose a deep-learning model for automating fetal organ classification from ultrasound images. We trained and tested the model on a dataset of fetal ultrasound images, including two datasets from different regions, and recorded them with different machines to ensure the effective detection of fetal organs. We performed a training process on a labeled dataset with annotations for fetal organs such as the brain, abdomen, femur, and thorax, as well as the maternal cervical part. The model was trained to detect these organs from fetal ultrasound images using a deep convolutional neural network architecture. Following the training process, the model, DenseNet169, was assessed on a separate test dataset. The results were promising, with an accuracy of 99.84%, which is an impressive result. The F1 score was 99.84% and the AUC was 98.95%. Our study showed that the proposed model outperformed traditional methods that relied on the manual interpretation of ultrasound images by experienced clinicians. In addition, it also outperformed other deep learning-based methods that used different network architectures and training strategies. This study may contribute to the development of more accessible and effective maternal health services around the world and improve the health status of mothers and their newborns worldwide.

Trends, Projections, and Regional Disparities of Maternal Mortality in Africa (1990-2030): An ARIMA Forecasting Approach

With the United Nations Sustainable Development Goals (SDG) (2015-2030) focused on the reduction in maternal mortality, monitoring and forecasting maternal mortality rates (MMRs) in regions like Africa is crucial for health strategy planning by policymakers, international organizations, and NGOs. We collected maternal mortality rates per 100,000 births from the World Bank database between 1990 and 2015. Joinpoint regression was applied to assess trends, and the autoregressive integrated moving average (ARIMA) model was used on 1990-2015 data to forecast the MMRs for the next 15 years. We also used the Holt method and the machine-learning Prophet Forecasting Model. The study found a decline in MMRs in Africa with an average annual percentage change (APC) of -2.6% (95% CI -2.7; -2.5). North Africa reported the lowest MMR, while East Africa experienced the sharpest decline. The region-specific ARIMA models predict that the maternal mortality rate (MMR) in 2030 will vary across regions, ranging from 161 deaths per 100,000 births in North Africa to 302 deaths per 100,000 births in Central Africa, averaging 182 per 100,000 births for the continent. Despite the observed decreasing trend in maternal mortality rate (MMR), the MMR in Africa remains relatively high. The results indicate that MMR in Africa will continue to decrease by 2030. However, no region of Africa will likely reach the SDG target.

Usefulness of the Hospital Information System for maternal mortality surveillance in Brazil

OBJECTIVE

To evaluate the capability of hospital records in the Hospital Information System (SIH) to add valuable and complementary information to the Mortality Information System (SIM) in studies on maternal mortality. We calculated and compared the maternal mortality ratio from the SIH and SIM databases, by age group and region, to highlight differences between groups and assess the coverage of maternal deaths using SIH compared with SIM.

METHODS

Obstetric hospitalizations were defined based on three sources (codes ICD-10 in diagnoses; procedures; billing information). Hospital and SIM mortality ratios were calculated by dividing maternal deaths in hospitals affiliated to the Unified Brazilian Health System (SUS) per live births (SINASC) in the same hospitals.

RESULTS

In 2019, we identified 2,497,957 obstetric admissions, 0.04% (946) with in-hospital mortality as outcome. The presence of three criteria identified 98% of obstetric hospitalizations and 83% of obstetric hospitalizations with death as outcome. The comparison of mortality ratios between SIH (45.5 MMR; 95%CI 42.7 - 48.5) and SIM (49.7 MMR; 95%CI 46.7 - 52.8) was not statistically significant (p-value: 0.053).

CONCLUSION

The analysis of SIH was able to provide additional information for the monitoring and surveillance of maternal health in Brazil. Although there are differences between the mortality rates, the SIH, as a complementary information system to the SIM, may be valid in studies on maternal mortality and morbidity.

Maternal Mortality in Africa: Regional Trends (2000-2017)

BACKGROUND

United Nations Sustainable Development Goals state that by 2030, the global maternal mortality rate (MMR) should be lower than 70 per 100,000 live births. MMR is still one of Africa's leading causes of death among women. The leading causes of maternal mortality in Africa are hemorrhage and eclampsia. This research aims to study regional trends in maternal mortality (MM) in Africa.

METHODS

We extracted data for maternal mortality rates per 100,000 births from the United Nations Children's Fund (UNICEF) databank from 2000 to 2017, 2017 being the last date available. Joinpoint regression was used to study the trends and estimate the annual percent change (APC).

RESULTS

Maternal mortality has decreased in Africa over the study period by an average APC of -3.0% (95% CI -2.9; -3,2%). All regions showed significant downward trends, with the greatest decreases in the South. Only the North African region is close to the United Nations' sustainable development goals for Maternal mortality. The remaining Sub-Saharan African regions are still far from achieving the goals.

CONCLUSIONS

Maternal mortality has decreased in Africa, especially in the South African region. The only region close to the United Nations' target is the North African region. The remaining Sub-Saharan African regions are still far from achieving the goals. The West African region needs more extraordinary efforts to achieve the goals of the United Nations. Policies should ensure that all pregnant women have antenatal visits and give birth in a health facility staffed by specialized personnel.

Maternal mortality decline in Zimbabwe, 2007/2008 to 2018/2019: findings from mortality surveys using civil registration, vital statistics and health system data

Background

Sustainable Development Goal (SDG) 3.1 target is to reduce the global maternal mortality ratio (MMR) to less than 70 maternal deaths per 100 000 live births by 2030. In the Ending Preventable Maternal Mortality strategy, a supplementary target was added, that no country has an MMR above 140 by 2030. We conducted two cross-sectional reproductive age mortality surveys to analyse changes in Zimbabwe’s MMR between 2007–2008 and 2018–2019 towards the SDG target.

Methods

We collected data from civil registration, vital statistics and medical records on deaths of women of reproductive ages (WRAs), including maternal deaths from 11 districts, randomly selected from each province (n=10) using cluster sampling. We calculated weighted mortality rates and MMRs using negative binomial models, with 95% CIs, performed a one-way analysis of variance of the MMRs and calculated the annual average reduction rate (ARR) for the MMR.

Results

In 2007–2008 we identified 6188 deaths of WRAs, 325 pregnancy-related deaths and 296 maternal deaths, and in 2018–2019, 1856, 137 and 130, respectively. The reproductive age mortality rate, weighted by district, declined from 11 to 3 deaths per 1000 women. The MMR (95% CI) declined from 657 (485 to 829) to 217 (164 to 269) deaths per 100 000 live births at an annual ARR of 10.1%.

Conclusions

Zimbabwe’s MMR declined by an annual ARR of 10.1%, against a target of 10.2%, alongside declining reproductive age mortality. Zimbabwe should continue scaling up interventions against direct maternal mortality causes to achieve the SDG 3.1 target by 2030.

Factors That Affect Maternal Mortality in Rwanda: A Comparative Study with India and Bangladesh

Healthcare sector is one of the most pivotal pillars of the administrative setup of a country. It addresses one of the most important dilemmas that countries have to face: provision of quality healthcare to public in affordable prices. Africa lags behind in many health indicators. One of the contemporary health issues faced by countries, especially for those in sub-Sahara countries, is maternal mortality rate (MMR). It has had a significant part to play in the social conditions of the population and needs immediate attention. In spite of many years of civil war and the terrible genocide in the mid-1990s, as of late, Rwanda is showing signs of improvement in healthcare sector. This research is aimed at studying the current state of maternal mortality rate in Rwanda and the factors behind its performance, in a comparative study with India and Bangladesh for a cross-section of time mainly between 1990 and 2015. After a literature review, pivotal indicators that affect healthcare are shortlisted and a comparative analysis of the three countries is made on the basis of these indicators. A regression is run between historical MMR data and these indicators. A directly significant relationship is found between MMR and healthcare expenditure per capita and government commitment to health, closely followed by female literacy and healthcare infrastructure.

Protocol for analysing the epidemiology of maternal mortality in Zimbabwe: A civil registration and vital statistics trend study

BACKGROUND

Sub-Saharan Africa (SSA) carries the highest burden of maternal mortality, yet, the accurate maternal mortality ratios (MMR) are uncertain in most SSA countries. Measuring maternal mortality is challenging in this region, where civil registration and vital statistics (CRVS) systems are weak or non-existent. We describe a protocol designed to explore the use of CRVS to monitor maternal mortality in Zimbabwe-an SSA country.

METHODS

In this study, we will collect deliveries and maternal death data from CRVS (government death registration records) and health facilities for 2007-2008 and 2018-2019 to compare MMRs and causes of death. We will code the causes of death using classifications in the maternal mortality version of the 10th revision to the international classification of diseases. We will compare the proportions of maternal deaths attributed to different causes between the two study periods. We will also analyse missingness and misclassification of maternal deaths in CRVS to assess the validity of their use to measure maternal mortality in Zimbabwe.

DISCUSSION

This study will determine changes in MMR and causes of maternal mortality in Zimbabwe over a decade. It will show whether HIV, which was at its peak in 2007-2008, remains a significant cause of maternal deaths in Zimbabwe. The study will recommend measures to improve the quality of CRVS data for future use to monitor maternal mortality in Zimbabwe and other SSA countries of similar characteristics.
