Global disparities in maternal morbidity and mortality

Design, construction, and validation of obstetric risk classification systems to predict intensive care unit admission

INTRODUCTION

To develop and validate a support tool for healthcare providers, enabling them to make precise and critical decisions regarding intensive care unit (ICU) admissions for high-risk pregnant women, thus enhancing maternal outcomes.

METHODS

This retrospective study involves secondary data analysis of information gathered from 9550 pregnant women, who had severe maternal morbidity (any unexpected complication during labor and delivery that leads to substantial short-term or long-term health issues for the mother), collected between 2009 and 2010 from the Brazilian Network for Surveillance of Severe Maternal Morbidity, encompassing 27 obstetric reference centers in Brazil. Machine-learning models, including decision trees, Random Forest, Gradient Boosting Machine (GBM), and Extreme Gradient Boosting (XGBoost), were employed to create a risk prediction tool for ICU admission. Subsequently, sensitivity analysis was conducted to compare the accuracy, predictive power, sensitivity, and specificity of these models, with differences analyzed using the Wilcoxon test.

RESULTS

The XGBoost algorithm demonstrated superior efficiency, achieving an accuracy rate of 85%, sensitivity of 42%, specificity of 97%, and an area under the receiver operating characteristic curve of 86.7%. Notably, the estimated prevalence of ICU utilization by the model (11.6%) differed from the prevalence of ICU use from the study (21.52%).

CONCLUSION

The developed risk engine yielded positive results, emphasizing the need to optimize intensive care bed utilization and objectively identify high-risk pregnant women requiring these services. This approach promises to enhance the effective and efficient management of pregnant women, particularly in resource-constrained regions worldwide. By streamlining ICU admissions for high-risk cases, healthcare providers can better allocate critical resources, ultimately contributing to improved maternal health outcomes.

Healthcare providers' psychological investment in clinical recommendations: Investigating the role of implicit racial attitudes

Racial disparities in clinical recommendations can result in racial disparities in health. While healthcare providers' implicit racial attitudes (affective component of bias) are theorized to be one major factor contributing to racial disparities in clinical recommendations, empirical evidence to support the link is lacking. This study aimed to bridge this gap by moving beyond the standard approach of operationalizing the quality of clinical recommendations as a guideline-consistent vs. -inconsistent dichotomy. The present secondary study examined the role of provider implicit racial attitudes in the quality of clinical recommendations, operationalized as behaviors reflecting providers' psychological investment in patient care (i.e., number of words used to describe clinical recommendations, and number of treatment options recommended). Two-hundred-and-ten White medical trainees reviewed a clinical vignette of either a White or Black male patient and provided clinical recommendations. Their implicit racial attitudes were evaluated using the Implicit Association Test. Participants with more biased implicit racial attitudes (i.e., stronger implicit preference for White vs. Black individuals) used fewer words to describe their clinical recommendations and provided fewer clinical recommendations for the Black (vs. White) patient, while there were no significant differences between Black and White patients among participants with less biased implicit racial attitudes. These results illustrate the insidious impact of implicit racial attitudes in healthcare provision and underscore the need for researchers to consider the complex, nuanced ways in which provider implicit racial attitudes might manifest in clinical decision-making.

Social Safety for Black Women in Perinatal Health Care: A Concept Analysis

INTRODUCTION

Non-Hispanic Black women and their infants experience the worst pregnancy-related outcomes in the United States. Social safety is a health-relevant resource found in environments communicating safety, connectedness, inclusion, and protection. Approaches promoting social safety may be particularly relevant to preventing adverse perinatal health outcomes among Black women. However, there remains a lack of conceptual clarity. The purpose of this concept analysis was to provide a theoretical clarification of the concept social safety for Black women within perinatal health care.

METHODS

PubMed, PsycINFO, and CINAHL were searched using Boolean search strategy. Retrieved articles were managed in Zotero. Duplicates were removed, and each article was assessed and categorized by both investigators. Articles reporting Black women's perinatal health care experiences were included. Thematic analysis guided by Rodgers' evolutionary method identified defining attributes, antecedents, and consequences of social safety in perinatal care for Black women.

RESULTS

Social safety for Black women is defined as the process of feeling understood, respected, cared for, and in control in perinatal health care settings that make space, care for, and recognize strengths, thereby cultivating safety and empowerment.

DISCUSSION

Social safety offers actionable insights for practice and research that have the potential to drive positive change in perinatal care delivery for Black women. Developing interventions and measurements that are valid, reliable, and reflect social safety are essential to promote positive experiences and equity in health care practices and policies.

Relationship between maternal arterial and foetal cord carbon dioxide tension and neonatal outcome in critically ill pregnant women at delivery

Background and Aims

No studies have evaluated the relationship between maternal arterial partial pressure of carbon dioxide (mPaCO2) and umbilical cord venous partial pressure of carbon dioxide (PCO2) in critically ill pregnant women at delivery. Based on the studies in healthy pregnant women, an mPaCO2 target of ≤50 mmHg is a suggested threshold during mechanical ventilation in critically ill parturients. We evaluated the relationship between mPaCO2 and neonatal cord gases in critically ill parturients at delivery as the primary objective. The relationship between mPaCO2 and APGAR scores at delivery was also analysed as a secondary objective.

Methods

Maternal and neonatal cord gas data at delivery and APGAR scores were obtained by a retrospective chart review of 25 consecutive parturients with severe respiratory compromise who were delivered during mechanical ventilation. Linear regression was used to assess the relationship between mPaCO2 and umbilical artery and vein PCO2 and between mPaCO2 and APGAR scores at 1 and 5 min.

Results

There was a positive correlation between mPaCO2 and neonatal cord venous PCO2 (P = 0.013). Foetal venous PCO2 exceeded predelivery mPaCO2 by 17.5 (7.5) mmHg. There was an inverse relationship between mPaCO2 and neonatal APGAR scores at 1 and 5 min (P = 0.006 and P = 0.007, respectively).

Conclusion

Foetal cord venous PCO2 can be predicted if mPaCO2 values are known. Unlike in healthy pregnant women, there was an inverse relationship between rising mPaCO2 levels and neonatal APGAR scores in critically ill pregnant women who had several associated compounding factors.

Social Determinant Pathways to Hypertensive Disorders of Pregnancy Among Nulliparous U.S. Women

BACKGROUND

Hypertensive disorders of pregnancy are a leading cause of maternal morbidity and mortality in the United States and impact Black mothers at disproportionately higher rates. Hypertensive disparities among racialized groups are rooted in systemic inequalities, and we hypothesize that clinical markers of allostatic load capture embodied disparities in stressors that can link upstream social determinants of health with downstream hypertensive outcomes.

METHODS

We analyzed observational cohort data from the Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (n = 6,501) and developed a structural equation model linking latent social determinants of health, longitudinal markers of allostatic load across gestation, and hypertensive pregnancy outcomes in a multigroup framework.

RESULTS

Non-Hispanic Black mothers-to-be (n = 1,155) showed higher rates of hypertensive disorders of pregnancy (32%) than non-Hispanic white women (n = 5,346, 23%). Among both groups, the social environment showed stronger direct effects on allostatic markers than via behaviorally mediated dietary, exercise, or smoking pathways. Demographic aspects of the social environment (e.g., household income, partnered status) were the most salient predictor of hypertensive risk and showed stronger effects among Black women.

CONCLUSIONS

Embodied stress rooted in the social environment is a major path driving maternal hypertensive disparities in the United States, with effects that vary across racialized groups. These pathway findings underscore the greater impact of systemic stressors relative to individual health behaviors. More comprehensive and detailed analyses of sociostructural domains are needed to identify promising avenues for policy and intervention to improve maternal health.

"We really are seeing racism in the hospitals": Racial identity, racism, and doula care for diverse populations in Georgia

INTRODUCTION

Poor birth outcomes are more prevalent for Black communities, but strong evidence shows that doula care can improve those outcomes. More evidence is needed to understand racial differences, discrimination, and equity in doula care.

METHODS

The current study's objective was to describe the experiences of Black doulas as well as the challenges and facilitators of providing doula care to communities of color in Georgia. From Fall 2020-Fall 2021, 20 surveys and in-depth interviews were conducted with doulas as part of a community-based participatory study co-led by Healthy Mothers, Healthy Babies Coalition of Georgia and academic researchers.

RESULTS

Doula participants were diverse in age (5% under 25, 40% 25-35, 35% 36-45, and 20% 46+) and race/ethnicity (45% white, 50% Black, 5% Latinx). Most (70%) Black doulas reported that more than 75% of their clientele is Black, while most (78%) white doulas reported that less than 25% of their clientele is Black. Doulas noted the alarming Black maternal mortality rate and how mistreatment causes Black clients to lose trust in medical staff, leaving them in need of advocates. Black doulas were passionate about serving and advocating with Black clients. Participants also described how language and cultural barriers, particularly for Asian and Latinx people, reduce clients' ability to self-advocate, increasing the need for doulas. Doulas also discussed the ways that race influences their connections with clients and their dissatisfaction with the lack of cultural humility or sensitivity training in standard doula training.

CONCLUSION

Our findings indicate that Black doulas provide essential and supportive services to Black birthing people, and those services are more urgently needed than ever following the overturn of Roe v. Wade. Doula training must be improved to address the cultural needs of diverse clients. Increasing access to doula care for Asian and Latinx communities could also address language and cultural barriers that can negatively impact their maternal and child health outcomes.

Cesarean delivery and risk of HIV vertical transmission in Southern Brazil, 2008-2018

BACKGROUND

Childbirth via cesarean delivery can prevent intrapartum vertical transmission for women who are not virally suppressed at the time of delivery. Few studies have compared cesarean delivery trends between women living with HIV and women without HIV and have examined the role of cesarean delivery in the prevention of vertical transmission in the era of potent combination antiretroviral therapy.

OBJECTIVE

We hypothesized that the cesarean delivery rate is high in women living with HIV compared with women without HIV and that cesarean delivery usage decreases over time among women living with HIV with advances in combined antiretroviral therapy in a country with a high national cesarean delivery rate. This study aimed (1) to evaluate cesarean delivery trends in women with and without HIV and (2) to examine its role in preventing vertical transmission among women living with HIV in a setting of free, universal combined antiretroviral therapy coverage in a retrospective cohort of nearly 56,000 deliveries at a major referral institution in a city with the highest prevalence of maternal HIV in Brazil.

STUDY DESIGN

Data from maternal-infant pairs from January 1, 2008, to December 31, 2018, were extracted. Cesarean delivery rates were compared using the Pearson chi-square test. Cesarean delivery predictors were evaluated by multivariate log-linear Poisson regression using a generalized estimating equations approach. HIV viral suppression was defined as a viral load of <1000 copies/ml at delivery. HIV vertical transmission was determined following national guidelines.

RESULTS

Over 11 years, 48,688 pregnancies occurred in 40,375 women; HIV seroprevalence was 2.7%; 18,886 cesarean deliveries (38.8%) were performed; 47.7% of women living with HIV and 38.6% of women without HIV underwent cesarean delivery (P<.001). Although HIV was associated with cesarean delivery (adjusted relative risk, 1.17 [95% confidence interval, 1.05-1.29]), women living with HIV with vertical transmission achieved similar cesarean delivery rates (36.7%) as women without HIV (39.8%) in 2018. Cesarean delivery in women living with HIV with an unknown viral load at delivery (42.6%) did not increase over time. HIV vertical transmission rate was 2.2%, the highest in women living with HIV with an unknown viral load (8.4%) vs women living with HIV without vertical transmission (4.1%) and women living with HIV with vertical transmission (0.5%) (P<.001).

CONCLUSION

In the HIV epicenter of Brazil, women living with HIV with vertical transmission had fewer surgical deliveries, likely because of the use of potent combination antiretroviral therapy. Nearly half of the women living with HIV with an unknown viral load did not undergo cesarean delivery, a potential missed opportunity for the prevention of HIV vertical transmission.

The relationship between maternal death due to COVID-19 and the human development index in East Java, Indonesia

Background

Maternal mortality rates and human development indexes can reflect a country's quality of health services. During the COVID-19 pandemic, these two achievement indicators are predicted to experience significant changes, and both have an interrelated relationship.

Objectives

To find the relationship between maternal death due to COVID-19 and the Human Development Index (HDI) in East Java, Indonesia.

Design and methods

A cross-sectional analytic study was carried out by processing secondary data from the provincial department of health regarding maternal mortality due to COVID-19 in East Java in 2020 and the HDI data from the Indonesian Central Statistics Agency. After that, the data were analyzed statistically using SPSS Statistics.

Results

The number of maternal deaths due to East Java's COVID-19 during 2020 was 793 out of 1280. Furthermore, the HDI reached 2744.6, the first dimension contains life expectancy reaching 2725.3, and the number of health workers 100,021. In the second dimension, the literacy rate reaches 3482.9, and the average length of schooling is 134,341. Moreover, the last dimension contains a total population density of 40,878,789, and a poverty rate of 4572.7. Statistical analysis results show a positive relationship between maternal mortality due to COVID-19 and HDI, with a p-value of 0.008.

Conclusion

There is a significant relationship between maternal mortality due to COVID-19 and HDI. However, the link between maternal mortality and COVID-19 related to the detailed dimensions contained in the HDI is not statistically related.

The landscape of disparities in obstetric neurocritical care and a path forward

Health disparities in the obstetric population affect maternal morbidity and mortality. In the past years, there has been no significant improvement in disparities in care in the obstetric population. Patients who are pregnant are known to have a higher risk of pregnancy-associated neurologic conditions such as stroke and intracerebral hemorrhage. They can also experience concomitant neurocritical care disease states such as status epilepticus and traumatic brain injury. Studies exploring the disparities of care among pregnant patients who are neurotically ill are lacking. We aim to provide the landscape of disparities of care among the obstetric neurocritically-ill population and provide potential actionable opportunities to address these disparities in care.

Assessment of maternal services in China based on WHO's comprehensive evaluation model

BACKGROUND

To understand the trend of equalization in maternal services and to guide policy-makers regarding resource allocation and public health policy in China.

METHODS

Twelve indicators, including maternal services needs, utilization, and resource allocation, were collected from China Health Statistical Year Book 2010 and 2020. WHO's comprehensive evaluation model and the non-integral Rank Sum Ratio (RSR) method were used to analyze, rank, and categorize maternal services of 31 provinces (cities, autonomous regions) in China.

RESULTS

All provinces (cities, autonomous regions) are grouped into relative balance areas, low input areas, resource shortage areas, overutilization areas, and resource waste areas. In 2019, there were 18 provinces (cities, autonomous regions) in the relative balanced area, and more than one-half had achieved equal development. Compared to 2009, the resource shortage area decreased from three to zero, and the resource waste area increased from four to six. Among the provinces (cities, autonomous regions) with a type change compared with 2009, eight changed to a relative balance areas, and four showed an improvement.

CONCLUSION

Under the policy guidance of promoting the equalization of public health services, maternal services are gradually realized. However, several provinces (cities, autonomous regions) still have problems such as the mismatch between resource input and health needs, resource waste, over-utilization, etc. Therefore, specific policies should be formulated according to the actual types to promote the transformation into equalization regions.

Health professionals' perspectives on clinical challenges in managing hypertensive disorders of pregnancy and recommendations for improving care: A multi-center qualitative study

Background

Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal mortality and morbidity globally despite the intensive international effort to improving maternal care. Substandard clinical care has emerged as a major contributing factor to the high maternal deaths associated with maternal hypertension globally and the impact is severer in low- and middle-income countries (LMICs). Context specific challenges impact negatively on the quality of maternity care and health providers play a crucial role in achieving positive pregnancy experiences for women. This study explored the perspectives of health professionals on the clinical challenges associated with the management of HDP in Ghana and recommendations for improving care.

Methods

A multi-center qualitative study using in-depth interviews (IDIs) was conducted in five major hospitals in the Greater Accra Region of Ghana between June 2018 and March 2019. Health professionals (midwives/nurses and medical doctors) who have worked at the study sites for at least three months were included. Data were analysed based on thematic content using Nvivo software.

Results

We included 62 health professionals comprising 40 midwives/nurses (64.5%) with a median age of 32.5 years (range 26 to 59) and 22 medical doctors (34.5%) with a median age of 34 years (range 25 to 55). Health providers highlighted major challenges associated with clinical management of hypertension in pregnancy: (1) patient-related factors (inadequate understanding and misconceptions about hypertension in pregnancy, women's non-compliance with clinical advice, financial constraints); (2) health system-related challenges (frequent unavailability of logistics, medications and laboratory support, delays in provision of care and limitations in the health insurance coverage); (3) health provider associated factors (inadequate number of health professionals and poor attitudes). Context-specific recommendations suggested for improving the quality of care in managing maternal hypertension include restructuring of the health system to reduce delays in providing care, improving financial coverage of medical insurance, encouraging social/family support, enhancing education on HDP and strengthening the health workers' numbers and working conditions.

Conclusion

Major challenges in the clinical management of HDP relate to the health system, health professionals and pregnant women themselves. Context-specific interventions are required to improve the quality of care for hypertensive mothers including regular health education, re-structuring of the health systems, refresher courses for health providers, improvement in health insurance coverage and government subsidy for hypertensive women.

Patterns of pregnancy loss among women living with and without HIV in Brazil, 2008-2018

BACKGROUND

Pregnancy loss is poorly understood, but infection may be a risk factor. Few studies have evaluated pregnancy loss among women living with HIV in the era of potent combination antiretroviral therapy.

OBJECTIVE

We hypothesize that maternal HIV and syphilis infection lead to increased risk of pregnancy loss, including both miscarriage and stillbirth. This study aimed to assess trends and possible predictors of spontaneous miscarriage and stillbirth among women living with HIV in a cohort of nearly 56,000 deliveries at a major referral institution in a city with the highest prevalence of HIV in Brazil.

STUDY DESIGN

Data from hospital records for women delivering from January 1, 2008 to December 31, 2018 were reviewed. Rates of stillbirth, miscarriage, and any pregnancy loss were compared using the Pearson chi-square test. Predictors of pregnancy loss were evaluated by robust univariate log-linear Poisson regression using a generalized estimating equations approach.

RESULTS

A total of 55,844 pregnancies were included in the analysis, with 54,308 pregnancies from 43,502 women without HIV and 1536 pregnancies from 1186 women living with HIV (seroprevalence of maternal HIV: 2.7%). Overall, 1130 stillbirths (2.0%) and 6558 miscarriages (11.7%) occurred. Any pregnancy loss was similar in both groups (13.8% in women without and 14.1% in women with HIV; P=.733). Stillbirth was higher among women living with HIV (3.4%) than among women without HIV (2.0%; P<.001), but there was no difference in overall miscarriage rates (10.7% in women with vs. 11.8% in women without HIV; P=.188). Women living with HIV had higher miscarriage rates between 12 and 20 weeks than women without HIV (34.8% vs 23.7%; P=.001), likely because of syphilis coinfection. Stillbirth rates were higher for women living with HIV from 2008 to 2014; however, a steady plateau was reached from 2014 to 2018, mirroring stillbirth rates in women without HIV. Maternal HIV infection did not increase the risk of miscarriage (relative risk, 0.90; 95% confidence interval, 0.77-1.05) or any pregnancy loss (relative risk, 1.00; 95% confidence interval, 0.88-1.15), but was associated with stillbirth (relative risk, 1.65; 95% confidence interval, 1.23-2.21). Maternal syphilis was associated with any pregnancy loss (relative risk, 1.24; 95% confidence interval, 1.11-1.38) and stillbirth (relative risk, 3.39; 95% confidence interval, 2.77-4.14), but not miscarriage (relative risk, 0.91; 95% confidence interval, 0.80-1.04).

CONCLUSION

In the era of combination antiretroviral therapy, there was no difference in miscarriage rates between women with and without HIV. HIV was associated with stillbirth risk but improved over time. Maternal syphilis was significantly associated with any pregnancy loss and stillbirth in all women. Syphilis is likely the main driver of pregnancy loss in women living with HIV in Brazil.

Birth, love, and fear: Physiological networks from pregnancy to parenthood

Pregnancy and childbirth are among the most dramatic physiological and emotional transformations of a lifetime. Despite their central importance to human survival, many gaps remain in our understanding of the temporal progression of and mechanisms underlying the transition to new parenthood. The goal of this paper is to outline the physiological and emotional development of the maternal-infant dyad from late pregnancy to the postpartum period, and to provide a framework to investigate this development using non-invasive timeseries. We focus on the interaction among neuroendocrine, emotional, and autonomic outputs in the context of late pregnancy, parturition, and post-partum. We then propose that coupled dynamics in these outputs can be leveraged to map both physiologic and pathologic pregnancy, parturition, and parenthood. This approach could address gaps in our knowledge and enable early detection or prediction of problems, with both personalized depth and broad population scale.

Clinical characteristics and risk factors for maternal deaths due to COVID-19 in Brazil: a nationwide population-based cohort study

BACKGROUND

Monitoring the characteristics and associated factors for death among pregnant and postpartum women with coronavirus disease 19 (COVID-19) is necessary. We investigated the clinical characteristics and risk factors associated with maternal deaths in a nationwide cohort of Brazil.

METHODS

This was a population-based cohort of all pregnant and postpartum women hospitalised with COVID-19 notified to the Sistema de Informação de Vigilância Epidemiológica da Gripe of Brazil (SIVEP-Gripe), from February 2020 to September 2021. The primary outcome was time to in-hospital death, with risk factors analysed with univariable and multivariable Cox proportional hazards regression models.

RESULTS

Cumulative observation time was 248 821 person-days from hospital admission to the end of follow-up for 15 105 individuals. There were 1858 deaths (12.3%) for a maternal mortality rate of 7.5 (95% CI 7.1-7.8) per 1000 patients-days. The cumulative mortality increased over time. Black/Brown ethnicity had a higher risk of death than women self-identifying as White. Women in the North, Northeast, Central-West and Southeast regions had higher risk of death than women in the South region. The characteristics independently associated with death were a postpartum status on admission [adjusted hazard ratio, HR 1.4 (95% confidence interval, CI 1.2-1.6)], pre-existing clinical conditions [adjusted HRs 1.2 (95%CI 1.1-1.3) for one and 1.3 (95%CI 1.1-1.5) for two comorbidities], hypoxaemia on admission [adjusted HR 1.2 (95%CI 1.1-1.4)] and requiring non-invasive [adjusted HR 2.6 (95%CI 2.1-3.3)] or invasive ventilatory support [adjusted HR 7.1 (95%CI 5.6-9.2)].

CONCLUSION

In Brazil, the in-hospital maternal mortality rate due to COVID-19 is high and the risk of death increases with the length of hospitalisation. Socio-demographic and biological factors are associated with an increased risk of maternal death. The presence of respiratory signs and symptoms should be considered early markers of disease severity and an adequate management is necessary. Our findings reinforce the need for vaccination of pregnant and postpartum women against COVID-19.

Squatting, pelvic morphology and a reconsideration of childbirth difficulties

 

Childbirth is commonly viewed as difficult in human females, encompassed by the 'Obstetrical Dilemma' (OD) described by early palaeoanthropologists as an evolved trade-off between a narrow pelvis necessitated by bipedalism and a large-brained fetal head. The OD has been challenged on several grounds. We add to these challenges by suggesting humans likely squatted regularly during routine tasks prior to the advent of farming societies and use of seats. We suggest that habitual squatting, together with taller stature and better nutrition of ancestral hunter-gatherers compared with later Neolithic and industrial counterparts, obviated an OD. Instead, difficulties with parturition may have arisen much later in our history, accompanying permanent settlements, poorer nutrition, greater infectious disease loads and negligible squatting in daily life. We discuss bioarchaeological and contemporary data that support these viewpoints, suggest ways in which this hypothesis might be tested further and consider its implications for obstetrical practice.

Lay Summary

Human childbirth is viewed as universally difficult. Evidence from physical therapies/engineering and studies of living and ancestral humans illustrates habitual squatting widens the pelvis and could improve childbirth outcomes. Obstetrical difficulties emerged late in prehistory accompanying settled agriculture, poorer nutrition and less squatting. Specific physical exercises could improve obstetrical practice.

"Once you get one maternal death, it's like the whole world is dropping on you": experiences of managing maternal mortality amongst obstetric care providers in Ghana

BACKGROUND

Maternal mortality has a significant global impact, especially in low-resource settings. Little prior research has been conducted on the potential effects of poor maternal outcomes on the personal and professional well-being of healthcare providers. This study explores the in-depth experiences and perspectives of obstetric providers in Ghana who work in a setting with frequent maternal mortalities.

METHODS

This is a qualitative study of semi-structured interviews conducted at the Komfo Anokye Teaching Hospital in Ghana. Participants were obstetric healthcare providers, defined as midwives, house officers currently rotating on the obstetrics/gynecology service, and obstetrician/gynecologists at any training or practice level (residents, fellows, and specialists). Interviews were audio-recorded, transcribed verbatim, and uploaded into NVivo for qualitative analysis. Using the Attride-Stirling qualitative model, an incremental and iterative process was used to code interviews with keyword phrases and develop a framework of organizing and global themes.

RESULTS

Interviews were conducted with 27 participants-15 midwives and 12 physicians (three obstetrician/gynecologist residents, six obstetrician/gynecologist specialists, and three house officers), with sample size determined by data saturation. Obstetric providers' experiences in a setting with frequent maternal mortalities were dependent on their level of preparedness to manage maternal mortalities and the workplace environment. Providers' level of preparedness was dependent on both the training they had received on the medical management of obstetric emergencies, as well as a lack of training on the mental health aspects of coping with maternal mortality. The impact of the workplace environment was dependent on systems failures and limited resources, blame from colleagues and supervisors, and a lack of support in the workplace. In turn, obstetric providers' experiences managing frequent maternal mortalities impacted their clinical care performance and mental health.

CONCLUSIONS

Maternal deaths have profound personal and professional impacts on the healthcare providers who manage them. A large need exists for additional institutional training and support for obstetric providers who manage maternal mortality, especially in low-resource settings like Ghana.

Health disparities, COVID-19, and maternal and childbirth outcomes: a meta-epidemiological study of equity reporting in systematic reviews

BACKGROUND

Pregnant women with COVID-19 are at increased risk for adverse maternal and pregnancy outcomes, and birth complications. Given the health outcome disparities among pregnant women of racial and ethnic minorities and the reliance of medical practice on systematic reviews and meta-analyses (SRMAs)-as they are the apical component in the hierarchy of evidence in medical research-the primary objective of the study is to examine the inclusion of the equity reporting in SRMAs focused on pregnancy outcomes and COVID-19 using PROGRESS-Plus equity framework. PROGRESS represents equity measures of Place, Race, Occupation, Gender, Religion, Education, Social capital, and Socio-economic status.

METHODS

We conducted a systematic search of three databases to identify SRMAs related to maternal and pregnancy outcomes related to COVID-19. We extracted whether SRMAs reported or analyzed PROGRESS-Plus components among other study characteristics.

RESULTS

Nearly 85% of SRMAs did not include any equity items to account for racial or geographic disparities. Reporting of race was absent from 95% of the studies. Place was the most common PROGRESS item and maternal age was the most common PROGRESS-Plus item reported overall.

CONCLUSION

When research is performed and reported in a way that fails to address disparities, the downstream repercussions may include medical care in the form of new protocol-driven hospital management, pharmacologic interventions, and other treatment options that mirror this absence in reporting. The absence of adequate reporting widens gaps in health outcomes among at-risk groups, such as pregnant women of racial and ethnic minorities.

No sonographer, no radiologist: New system for automatic prenatal detection of fetal biometry, fetal presentation, and placental location

Ultrasound imaging is a vital component of high-quality Obstetric care. In rural and under-resourced communities, the scarcity of ultrasound imaging results in a considerable gap in the healthcare of pregnant mothers. To increase access to ultrasound in these communities, we developed a new automated diagnostic framework operated without an experienced sonographer or interpreting provider for assessment of fetal biometric measurements, fetal presentation, and placental position. This approach involves the use of a standardized volume sweep imaging (VSI) protocol based solely on external body landmarks to obtain imaging without an experienced sonographer and application of a deep learning algorithm (U-Net) for diagnostic assessment without a radiologist. Obstetric VSI ultrasound examinations were performed in Peru by an ultrasound operator with no previous ultrasound experience who underwent 8 hours of training on a standard protocol. The U-Net was trained to automatically segment the fetal head and placental location from the VSI ultrasound acquisitions to subsequently evaluate fetal biometry, fetal presentation, and placental position. In comparison to diagnostic interpretation of VSI acquisitions by a specialist, the U-Net model showed 100% agreement for fetal presentation (Cohen's κ 1 (p<0.0001)) and 76.7% agreement for placental location (Cohen's κ 0.59 (p<0.0001)). This corresponded to 100% sensitivity and specificity for fetal presentation and 87.5% sensitivity and 85.7% specificity for anterior placental location. The method also achieved a low relative error of 5.6% for biparietal diameter and 7.9% for head circumference. Biometry measurements corresponded to estimated gestational age within 2 weeks of those assigned by standard of care examination with up to 89% accuracy. This system could be deployed in rural and underserved areas to provide vital information about a pregnancy without a trained sonographer or interpreting provider. The resulting increased access to ultrasound imaging and diagnosis could improve disparities in healthcare delivery in under-resourced areas.

Number of antenatal care utilization and associated factors among pregnant women in Ethiopia: zero-inflated Poisson regression of 2019 intermediate Ethiopian Demography Health Survey

BACKGROUND

The frequency of antenatal care utilization enhances the effectiveness of the maternal health programs to maternal and child health. The aim of the study was to determine the number of antenatal care and associated factors in Ethiopia by using 2019 intermediate EDHS.

METHODS

Secondary data analysis was done on 2019 intermediate EDHS. A total of 3916.6 weighted pregnant women were included in the analysis. Zero-inflated Poisson regression analysis was done by Stata version 14.0. Incident rate ratio and odds ratio with a 95% confidence interval were used to show the strength and direction of the association.

RESULT

About one thousand six hundred eighty eight (43.11%) women were attending four and more antenatal care during current pregnancy. Attending primary education (IRR = 1.115, 95% CI: 1.061, 1.172), secondary education (IRR = 1.211, 95% CI: 1.131, 1.297) and higher education (IRR = 1.274, 95% CI: 1.177, 1.378), reside in poorer household wealth index (IRR = 1.074, 95% CI: 1.01, 1.152), middle household wealth index (IRR = 1.095, 95% CI: 1.018, 1.178), rich household wealth index (IRR = 1.129, 95% CI: 1.05, 1.212) and richer household wealth index (IRR = 1.186, 95% CI: 1.089, 1.29) increases the number of antenatal care utilization. The frequency of antenatal care was less likely become zero among women attending primary (AOR = 0.434, 95% CI: 0.346, 0.545), secondary (AOR = 0.113, 95% CI: 0.053, 0.24), higher educational level (AOR = 0.052, 95% CI: 0.007, 0.367) in the inflated part.

CONCLUSION

The number of antenatal care utilization is low in Ethiopia. Being rural, poorest household index, uneducated and single were factors associated with low number of antenatal care and not attending antenatal care at all. Improving educational coverage and wealth status of women is important to increase the coverage and frequency of antenatal care.

A national cohort study and confidential enquiry to investigate ethnic disparities in maternal mortality

BACKGROUND

Ethnic disparities in maternal mortality were first documented in the UK in the early 2000s but are known to be widening. This project aimed to describe the women who died in the UK during or up to a year after the end of pregnancy, to compare the quality of care received by women from different aggregated ethnic groups, and to identify any structural or cultural biases or discrimination affecting their care.

METHODS

National surveillance data was used to identify all 1894 women who died during or up to a year after the end of pregnancy between 2009 and 18 in the UK. Their characteristics and causes of death were described. A Confidential Enquiry was undertaken to describe the quality of care women received. The care of a stratified random sample of 54 women who died during or up to a year after the end of pregnancy between 2009 and 18, (18 from the aggregated group of Black women, 19 from the Asian aggregated group and 17 from the White aggregated group) was re-examined specifically to describe any structural or cultural biases or discrimination identified.

FINDINGS

There were no major differences causes of death between women from different aggregated ethnic groups, with cardiovascular disease the leading cause of death in all groups. Multiple areas of bias were identified in the care women received, including lack of nuanced care (notable amongst women from Black aggregated ethnic groups who died), microaggressions (most prominent in the care of women from Asian aggregated ethnic groups who died) and clinical, social and cultural complexity (evident across all ethnic groups).

INTERPRETATION

This confidential enquiry suggests that multiple structural and other biases exist in UK maternity care. Further research on the role of microaggressions is warranted.

Women and babies are dying from inertia: a collaborative framework for obstetrical drug development is urgently needed

Obstetrical complications, often referred to as the "great obstetrical syndromes," are among the most common global causes of mortality and morbidity in young women and their infants. However, treatments for these syndromes are underdeveloped compared with other fields of medicine and are urgently needed. This current paucity of treatments for obstetrical complications is a reflection of the challenges of drug development in pregnancy. The appetite of pharmaceutical companies to invest in research for obstetrical syndromes is generally reduced by concerns for maternal, fetal, and infant safety, poor definition, and high-risk regulatory paths toward product approval. Notably, drug candidates require large investments for development with an unguaranteed return on investment. Furthermore, the discovery of promising drug candidates is hampered by a poor understanding of the pathophysiology of obstetrical syndromes and their uniqueness to human pregnancies. This limits translational extrapolation and de-risking strategies in preclinical studies, as available for other medical areas, compounded with limited fetal safety monitoring to capture early prenatal adverse reactions. In addition, the ethical review committees are reluctant to approve the inclusion of pregnant women in trials, and in the absence of regulatory guidance in obstetrics, clinical development programs are subject to unpredictable regulatory paths. To develop effective and safe drugs for pregnancy complications, substantial commitment, and investment in research for innovative therapies are needed in parallel with the creation of an enabling ethical, legislative, and guidance framework. Solutions are proposed to enable stakeholders to work with a common set of expectations to facilitate progress in this medical discipline. Addressing this significant unmet need to advance maternal and possibly perinatal health requires the involvement of all stakeholders and specifically patients, couples, and clinicians facing pregnancy complications in the dearth of appropriate therapies. This paper focused on the key pharmaceutical research and development challenges to achieve effective and safe treatments for obstetrical syndromes.

Race inequalities in maternal mortality in the city of Rio de Janeiro, Brazil: 2010-2019

OBJECTIVE

To analyze the behavior of maternal mortality according to the race/color variable in the city of Rio de Janeiro, Brazil, between 2010 and 2019.

METHODS

This is a cross-sectional study that used microdata collected in the Sistema de Informações sobre Mortalidade and Sistema de Informações sobre Nascidos Vivos. Data were disaggregated by race/color and age groups of childbearing age. Pearson's χ2 test was used to compare the ratio in each category of covariates. In order to explore the differences in the maternal mortality ratio of the respective variables, the data were adjusted using Poisson's model. Polynomial regression models were tested to describe the trend.

RESULTS

There were 732 maternal deaths in the city of Rio de Janeiro between 2010 and 2019. The time trend analysis of general maternal mortality showed a significant decline between 2010 and 2018 followed by a new upward trend in 2019. There was a greater maternal mortality ratio for older age groups, especially for women over 40 (prevalence ratio of 18.80, 95%CI 13.54-26.78; p<0.0001) and black ones (prevalence ratio of 2.31, 95%CI 1.90-2.80; p<0.0001).

CONCLUSION

There is evidence that maternal mortality is associated with issues of race, which suggests the racial disparity in obstetric care in the city of Rio de Janeiro.

Testing telediagnostic obstetric ultrasound in Peru: a new horizon in expanding access to prenatal ultrasound

Background

Ninety-four percent of all maternal deaths occur in low- and middle-income countries, and the majority are preventable. Access to quality Obstetric ultrasound can identify some complications leading to maternal and neonatal/perinatal mortality or morbidity and may allow timely referral to higher-resource centers. However, there are significant global inequalities in access to imaging and many challenges to deploying ultrasound to rural areas. In this study, we tested a novel, innovative Obstetric telediagnostic ultrasound system in which the imaging acquisitions are obtained by an operator without prior ultrasound experience using simple scan protocols based only on external body landmarks and uploaded using low-bandwidth internet for asynchronous remote interpretation by an off-site specialist.

Methods

This is a single-center pilot study. A nurse and care technician underwent 8 h of training on the telediagnostic system. Subsequently, 126 patients (68 second trimester and 58 third trimester) were recruited at a health center in Lima, Peru and scanned by these ultrasound-naïve operators. The imaging acquisitions were uploaded by the telemedicine platform and interpreted remotely in the United States. Comparison of telediagnostic imaging was made to a concurrently performed standard of care ultrasound obtained and interpreted by an experienced attending radiologist. Cohen’s Kappa was used to test agreement between categorical variables. Intraclass correlation and Bland-Altman plots were used to test agreement between continuous variables.

Results

Obstetric ultrasound telediagnosis showed excellent agreement with standard of care ultrasound allowing the identification of number of fetuses (100% agreement), fetal presentation (95.8% agreement, κ =0.78 (p < 0.0001)), placental location (85.6% agreement, κ =0.74 (p < 0.0001)), and assessment of normal/abnormal amniotic fluid volume (99.2% agreement) with sensitivity and specificity > 95% for all variables. Intraclass correlation was good or excellent for all fetal biometric measurements (0.81–0.95). The majority (88.5%) of second trimester ultrasound exam biometry measurements produced dating within 14 days of standard of care ultrasound.

Conclusion

This Obstetric ultrasound telediagnostic system is a promising means to increase access to diagnostic Obstetric ultrasound in low-resource settings. The telediagnostic system demonstrated excellent agreement with standard of care ultrasound. Fetal biometric measurements were acceptable for use in the detection of gross discrepancies in fetal size requiring further follow up.

Are we listening? Obstetric anesthesiology and the national call for birth justice and accountability: a perspective from the United States

Despite declining rates of pregnancy-related deaths worldwide, the United States (US) has seen an increase in maternal mortality. It is widely known that this increased risk of mortality impacts unevenly Black people, who are three-fold more likely to die from pregnancy-related causes than white people. This disparity in maternal mortality and morbidity is not unique to the US; countries like Brazil, the Netherlands, South Africa, and the United Kingdom (UK) report similar racial disparities in peripartum health outcomes. It is thought that many factors contribute to this tragic health inequity, including, but not limited to, structural racism, provider implicit bias, and lack of access to high quality, culturally humble reproductive health care. On July 25, 2020, activists for reproductive justice and birth justice published an open call in the New York Times entitled "How many Black, Brown, and Indigenous people have to die giving birth? National call for birth justice and accountability." It is a powerful statement that uses an intersectional framework to understand reproductive inequities, while making demands for positive healthcare reforms and radically dreaming of a reality where the struggle for reproductive justice has been actualized. Using personal narrative, this paper reflects on the field of obstetric anesthesiology and how clinicians can make meaningful change to address and eventually help solve this health care inequity.

The impact of chronic kidney disease Stages 3-5 on pregnancy outcomes

Background

Contemporaneous data are required for women with chronic kidney disease (CKD) Stages 3–5 to inform pre-pregnancy counselling and institute appropriate antenatal surveillance.

Methods

A retrospective cohort study in women with CKD Stages 3–5 after 20 weeks’ gestation was undertaken in six UK tertiary renal centres in the UK between 2003 and 2017. Factors predicting adverse outcomes and the impact of pregnancy in accelerating the need for renal replacement therapy (RRT) were assessed.

Results

There were 178 pregnancies in 159 women, including 43 women with renal transplants. The live birth rate was 98%, but 56% of babies were born preterm (before 37 weeks’ gestation). Chronic hypertension was the strongest predictor of delivery before 34 weeks’ gestation. Of 121 women with known pre-pregnancy hypertension status, the incidence of delivery before 34 weeks was 32% (31/96) in women with confirmed chronic hypertension compared with 0% (0/25) in normotensive women. The risk of delivery before 34 weeks doubled in women with chronic hypertension from 20% [95% confidence interval (CI) 9–36%] to 40% (95% CI 26–56%) if the gestational fall in serum creatinine was <10% of pre-pregnancy concentrations. Women with a urinary protein:creatinine ratio >100 mg/mmol prior to pregnancy or before 20 weeks’ gestation had an increased risk for birthweight below the 10th centile (odds ratio 2.57, 95% CI 1.20–5.53). There was a measurable drop in estimated glomerular filtration rate (eGFR) between pre-pregnancy and post-partum values (4.5 mL/min/1.73 m²), which was greater than the annual decline in eGFR prior to pregnancy (1.8 mL/min/1.73 m²/year). The effect of pregnancy was, therefore, equivalent to 1.7, 2.1 and 4.9 years of pre-pregnancy renal disease in CKD Stages 3a, 3b and 4–5, respectively. The pregnancy-associated decline in renal function was greater in women with chronic hypertension and in those with a gestational fall in serum creatinine of <10% of pre-pregnancy concentrations. At 1 year post-partum, 46% (58/126) of women had lost ≥25% of their pre-pregnancy eGFR or required RRT. Most women with renal transplants had CKD Stage 3 and more stable renal function prior to pregnancy. Renal transplantation was not independently associated with adverse obstetric or renal outcomes.

Conclusions

Contemporary pregnancies in women with CKD Stages 3–5 are complicated by preterm delivery, low birthweight and loss of maternal renal function. Chronic hypertension, pre- or early pregnancy proteinuria and a gestational fall in serum creatinine of <10% of pre-pregnancy values are more important predictors of adverse obstetric and renal outcome than CKD Stages 3–5. Pregnancy in women with CKD Stages 3–5 advances the need for dialysis or transplantation by 2.5 years.

Towards a better understanding of risk selection in maternal and newborn care: A systematic scoping review

Globally, millions of women and their children suffer due to preventable morbidity and mortality, associated with both underuse and overuse of maternal and newborn care. An effective system of risk selection that differentiates between what care should be provided and who should provide it is a global necessity to ensure women and children receive appropriate care, at the right place and the right time. Poor conceptualization of risk selection impedes evaluation and comparison of models of risk selection across various settings, which is necessary to improve maternal and newborn care. We conducted a scoping review to enhance the understanding of risk selection in maternal and newborn care. We included 210 papers, published over the past four decades, originating from 24 countries. Using inductive thematic analysis, we identified three main dimensions of risk selection: (1) risk selection as an organisational measure to optimally align women's and children's needs and resources, (2) risk selection as a practice to detect and assess risk and to make decisions about the delivery of care, and (3) risk selection as a tool to ensure safe care. We found that these three dimensions have three themes in common: risk selection (1) is viewed as both requiring and providing regulation, (2) has a provider centred focus and (3) aims to avoid underuse of care. Due to the methodological challenges of contextual diversity, the concept of risk selection needs clear indicators that capture the complexity of care to make cross-setting evaluation and comparison of risk selection possible. Moreover, a comprehensive understanding of risk selection needs to consider access disparity, women's needs, and unnecessary medicalization.

Skin Color and Severe Maternal Outcomes: Evidence from the Brazilian Network for Surveillance of Severe Maternal Morbidity

Background

Taking into account the probable role that race/skin color may have for determining outcomes in maternal health, the objective of this study was to assess whether maternal race/skin color is a predictor of severe maternal morbidity.

Methods

This is a secondary analysis of the Brazilian Network for Surveillance of Severe Maternal Morbidity, a national multicenter cross-sectional study of 27 Brazilian referral maternity hospitals. A prospective surveillance was performed to identify cases of maternal death (MD), maternal near miss (MNM) events, and potentially life-threatening conditions (PLTC), according to standard WHO definition and criteria. Among 9,555 women with severe maternal morbidity, data on race/skin color was available for 7,139 women, who were further divided into two groups: 4,108 nonwhite women (2,253 black and 1,855 from other races/skin color) and 3,031 white women. Indicators of severe maternal morbidity according to WHO definition are shown by skin color group. Adjusted Prevalence Ratios (PR_adj - 95%CI) for Severe Maternal Outcome (SMO=MNM+MD) were estimated according to sociodemographic/obstetric characteristics, pregnancy outcomes, and perinatal results considering race.

Results

Among 7,139 women with severe maternal morbidity evaluated, 90.5% were classified as PLTC, 8.5% as MNM, and 1.6% as MD. There was a significantly higher prevalence of MNM and MD among white women. MNMR (maternal near miss ratio) was 9.37 per thousand live births (LB). SMOR (severe maternal outcome ratio) was 11.08 per 1000 LB, and MMR (maternal mortality ratio) was 170.4 per 100,000 LB. Maternal mortality to maternal near miss ratio was 1 to 5.2, irrespective of maternal skin color. Hypertension, the main cause of maternal complications, affected mostly nonwhite women. Hemorrhage, the second more common cause of maternal complication, predominated among white women. Nonwhite skin color was associated with a reduced risk of SMO in multivariate analysis.

Conclusion

Nonwhite skin color was associated with a lower risk for severe maternal outcomes. This result could be due to confounding factors linked to a high rate of Brazilian miscegenation.

[Quality of maternal mortality statistics in Cuba, 2013Qualidade das estatísticas de mortalidade materna em Cuba, 2013]

Objetivos

Evaluar el grado de integridad del registro estadístico cubano de muertes maternas y la calidad de la clasificación de las causas de muerte recogidas en ese registro.

Métodos

Se analizó la información de todas las cubanas fallecidas en edad fértil en el año 2013 según el registro continuo de mortalidad de la Dirección de Registros Médicos y Estadísticas de Salud del Ministerio de Salud Pública de Cuba (MINSAP), independientemente de la causa básica de muerte consignada. Cuatro grupos de investigación (nacional, de expertos, provincial y de unidades de salud), con funciones definidas, aplicaron cuatro formularios para determinar si hubo embarazo en el año previo a la defunción, reevaluar si los casos correspondían a una muerte materna y, en ese caso, revisar la clasificación.

Resultados

Se investigaron las 2 731 mujeres fallecidas en edad reproductiva notificadas en Cuba en el 2013; de ellas las causas de muerte de 2 711 (99,3%) resultaron concluyentes y, de estas, 97 (3,6%) habían tenido un embarazo en el año previo a la defunción. Se encontraron 50 muertes maternas (una más que en el registro continuo) para 2% de error y un factor de ajuste de 1,02. De las 97 muertes estudiadas, solo se reclasificaron 4 casos: 2 muertes maternas y 1 muerte relacionada con el embarazo, el parto y el puerperio, según el registro continuo, que se reclasificaron como muertes directas, y 1 muerte considerada no materna por el registro continuo que se reclasificó como muerte materna tardía, para una concordancia de 95,9%.

Conclusiones

La información sobre las muertes maternas recogida en el registro continuo de mortalidad del MINSAP tiene un alto nivel de integridad. La calidad de la clasificación de las muertes maternas en ese registro es elevada, al existir muy pocos cambios en la reclasificación de las causas de muerte.

Challenges to the improvement of obstetric care in maternity hospitals of a large Brazilian city: an exploratory qualitative approach on contextual issues

BACKGROUND

Maternal morbidity and mortality are still serious public health concerns in Brazil, and access to quality obstetric care is one critical point of this problem. Despite efforts, obstetric care quality problems and sub-optimal/poor outcomes persist. The study aimed to identify contextual elements that would potentially affect the implementation of an obstetric care quality improvement intervention.

METHODS

A qualitative study was conducted in three public maternity hospitals of a large Brazilian city, with high annual volume of births and buy-in from high-level managers. Individual interviews with doctors and nurses were conducted from July to October 2015. Semi-structured interviews sought to explore teamwork, coordination and communication, and leadership, being open to capture other contextual elements that could emerge. Interviews were recorded and transcribed, and the categories of analysis were identified and updated based on the constant comparative method.

RESULTS

Twenty-seven interviews were carried out. Extra-organizational context concerning the dependence of the maternity hospitals on primary care units, responsible for antenatal care, and on other healthcare organizations' services emerged from interviews, but the main findings of the study centered on intra-organizational context with potential to affect healthcare quality and actions for its improvement, including material resources, work organization design, teamwork, coordination and communication, professional responsibility vis-à-vis the patient, and leadership. A major issue was the divergence of physicians' and nurses' perspectives on care quality, which in turn negatively affected their capacity to work together.

CONCLUSION

Overall, the findings suggest that care on the maternity hospitals was fragmented and lacked continuity, putting at risk the quality. Redesigning work organization, promoting conditions for multi-professional teamwork, better communication and coordination, improving more systemic accountability/lines of authority, and investing in team members' technical competence, and fitness of organizational structures and processes are all imbricated actions that may contribute to obstetric care quality improvement.
