Maternal Mortality in the United States: Trends and Opportunities for Prevention.

Maternal mortality is unusually high in the United States compared to other wealthy nations and is characterized by major disparities in race/ethnicity, geography, and socioeconomic factors. Similar to other developed nations, the United States has seen a shift in the underlying causes of pregnancy-related death, with a relative increase in mortality resulting from diseases of the cardiovascular system and preexisting medical conditions. Improved continuity of care aimed at identifying reproductive-age women with preexisting conditions that may heighten the risk of maternal death, preconception management of risk factors for major adverse pregnancy outcomes, and primary care visits within the first year after delivery may offer opportunities to address gaps in medical care contributing to the unacceptable rates of maternal mortality in the United States.

Anesthetic Care of the Pregnant Patient With Cardiovascular Disease: A Scientific Statement From the American Heart Association.

The pregnancy-related mortality rate in the United States is excessively high. The American Heart Association is dedicated to fighting heart disease and recognizes that cardiovascular disease, preexisting or acquired during pregnancy, is the leading cause of maternal mortality in the United States. Comprehensive scientific statements from cardiology and obstetrics experts guide the treatment of cardio-obstetric patients before, during, and after pregnancy. This scientific statement aims to highlight the role of specialized cardio-obstetric anesthesiology care, presenting a systematic approach to the care of these patients from the anesthesiology perspective. The anesthesiologist is a critical part of the pregnancy heart team as the perioperative physician who is trained to prevent or promptly recognize and treat patients with peripartum cardiovascular decompensation. Maternal morbidity is attenuated with expert anesthesiology peripartum care, which includes the management of neuraxial anesthesia, inotrope and vasopressor support, transthoracic echocardiography, optimization of delivery location, and consideration of advanced critical care and mechanical support when needed. Standardizing the anesthesiology approach to patients with high peripartum cardiovascular risk and ensuring that cardio-obstetrics patients have access to the appropriate care team, facilities, and advanced cardiovascular therapies will contribute to improving peripartum morbidity and mortality.

Shortcomings and disparities in contraception counseling and use by hypertensive individuals at risk for unintended pregnancy: a comparative analysis of the National Survey of Family Growth.

BACKGROUND: Hypertension is a leading cause of adverse pregnancy outcomes. These outcomes disproportionately affect Black individuals. Reproductive life planning that includes patient-centered contraception counseling could mitigate the impact of unintended pregnancy. OBJECTIVE: The primary objective of the study is to compare contraception counseling and use between hypertensive and nonhypertensive individuals at risk for unintended pregnancy. Our secondary objectives are the following: (1) to evaluate the effect of race on the probability of counseling and the use of contraception, and (2) to evaluate the methods used by individuals with hypertension. METHODS: Data from the 2015-2017 and 2017-2019 National Survey of Family Growth Female Respondent Files were used to analyze whether individuals who reported being informed of having high blood pressure within the previous 12 months received counseling about contraception or received a contraceptive method. Covariates considered in the analysis included age, race, parity, educational attainment, body mass index, smoking, diabetes, and experience with social determinants of health. The social determinants of health covariate was based on reported experiences within 5 social determinants of health domains: food security, housing stability, financial security, transportation access, and childcare needs. Linear probability models were used to estimate the adjusted probability of receiving counseling and the use of a contraceptive. Using difference-in-difference analyses, we compared the change in counseling and use between hypertensive and nonhypertensive respondents by race, relative to White respondents. RESULTS: Of the 8625 participants analyzed, 771 (9%) were hypertensive. Contraception counseling was received by 26.2% (95% confidence interval, 20.4-31.9) of hypertensive individuals and 20.7% (95% confidence interval, 19.3-22.2) of nonhypertensive individuals. Contraception use was reported by 39.8% (95% confidence interval, 33.2-46.5) of hypertensive and 35.3% (95% confidence interval, 33.3-37.2) of nonhypertensive individuals. The linear probability model adjusting for age, parity, education attainment, body mass index, smoking, diabetes, and social determinants of health indicated that hypertensive individuals were 8 percentage points (95% confidence interval, 3-18 percentage points) more likely to receive counseling and 9 percentage points (95% confidence interval, 3-16 percentage points) more likely to use contraception. Hypertensive Black individuals did not receive more counseling or use more contraceptives compared with nonhypertensive Black individuals. The difference in counseling when hypertension was present was 13 percentage points lower than the difference observed for White respondents when hypertension was present (P=.01). The most frequently used contraceptive method among hypertensive individuals was combined oral contraceptive pills (54.0%; 95% confidence interval, 44.3%-63.5%). CONCLUSION: Despite the higher likelihood of receiving contraception counseling and using contraception among hypertensive individuals at risk for unintended pregnancy, two-thirds of this population did not receive contraception counseling, and <40% used any contraceptive method. Furthermore, unlike White individuals, Black individuals with hypertension did not receive more contraception care than nonhypertensive Black individuals. Of all those who used contraception, half relied on a method classified as Centers for Disease Control and Prevention Medical Eligibility Criteria Category 3. These findings highlight a substantial unmet need for safe and accessible contraception options for hypertensive individuals at risk for unintended pregnancy, emphasizing the importance of targeted interventions to improve contraceptive care and counseling in this population.

Society for Maternal-Fetal Medicine Position Statement: Access to abortion care.

POSITION: The Society for Maternal-Fetal Medicine supports the right of all individuals to access the full spectrum of reproductive health services, including abortion care. Reproductive health decisions are best made by each individual with guidance and support from their healthcare providers. The Society opposes legislation and policies that limit access to abortion care or criminalize abortion care and self-managed abortion. In addition, the Society opposes policies that compromise the patient-healthcare provider relationship by limiting a healthcare provider's ability to counsel patients and provide evidence-based, medically appropriate treatment.

Agnostic identification of plasma biomarkers for postpartum hemorrhage risk.

BACKGROUND: Postpartum hemorrhage is difficult to predict, is associated with significant maternal morbidity, and is the leading cause of maternal mortality worldwide. The identification of maternal biomarkers that can predict increased postpartum hemorrhage risk would enhance clinical care and may uncover mechanisms that lead to postpartum hemorrhage. OBJECTIVE: This retrospective case-control study employed agnostic proteomic profiling of maternal plasma samples to identify differentially abundant proteins in controls and postpartum hemorrhage cases. STUDY DESIGN: Maternal plasma samples were procured from a cohort of >60,000 participants in a single institution's perinatal repository. Postpartum hemorrhage was defined as a decrease in hematocrit of ≥10% or receipt of transfusion within 24 hours after delivery. Postpartum hemorrhage cases (n=30) were matched by maternal age and delivery mode (vaginal or cesarean) with controls (n=56). Mass spectrometry was used to identify differentially abundant proteins using integrated peptide peak areas. Statistically significant differences between groups were defined as P<.05 after controlling for multiple comparisons. RESULTS: By study design, cases and controls did not differ in race, ethnicity, gestational age at delivery, blood type, or predelivery platelet count. Cases had slightly but significantly lower predelivery and postdelivery hematocrit and hemoglobin. Mass spectrometry detected 1140 proteins, including 77 proteins for which relative abundance differed significantly between cases and controls (fold change >1.15, P<.05). Of these differentially abundant plasma proteins, most had likely liver or placental origins. Gene ontology term analysis mapped to protein clusters involved in responses to wound healing, stress response, and host immune defense. Significantly differentially abundant proteins with the highest fold change (prostaglandin D2 synthase, periostin, and several serine protease inhibitors) did not correlate with predelivery hematocrit or hemoglobin but identified postpartum hemorrhage cases with logistic regression modeling revealing good-to-excellent area under the operator receiver characteristic curves (0.802-0.874). Incorporating predelivery hemoglobin with these candidate proteins further improved the identification of postpartum hemorrhage cases. CONCLUSION: Agnostic analysis of maternal plasma samples identified differentially abundant proteins in controls and postpartum hemorrhage cases. Several of these proteins are known to participate in biologically plausible pathways for postpartum hemorrhage risk and have potential value for predicting postpartum hemorrhage. These findings identify candidate protein biomarkers for future validation and mechanistic studies.

Maternal mortality in the United States: are the high and rising rates due to changes in obstetrical factors, maternal medical conditions, or maternal mortality surveillance?

BACKGROUND: National Vital Statistics System reports show that maternal mortality rates in the United States have nearly doubled, from 17.4 in 2018 to 32.9 per 100,000 live births in 2021. However, these high and rising rates could reflect issues unrelated to obstetrical factors, such as changes in maternal medical conditions or maternal mortality surveillance (eg, due to introduction of the pregnancy checkbox). OBJECTIVE: This study aimed to assess if the high and rising rates of maternal mortality in the United States reflect changes in obstetrical factors, maternal medical conditions, or maternal mortality surveillance. STUDY DESIGN: The study was based on all deaths in the United States from 1999 to 2021. Maternal deaths were identified using the following 2 approaches: (1) per National Vital Statistics System methodology, as deaths in pregnancy or in the postpartum period, including deaths identified solely because of a positive pregnancy checkbox, and (2) under an alternative formulation, as deaths in pregnancy or in the postpartum period, with at least 1 mention of pregnancy among the multiple causes of death on the death certificate. The frequencies of major cause-of-death categories among deaths of female patients aged 15 to 44 years, maternal deaths, deaths due to obstetrical causes (ie, direct obstetrical deaths), and deaths due to maternal medical conditions aggravated by pregnancy or its management (ie, indirect obstetrical deaths) were quantified. RESULTS: Maternal deaths, per National Vital Statistics System methodology, increased by 144% (95% confidence interval, 130-159) from 9.65 in 1999-2002 (n=1550) to 23.6 per 100,000 live births in 2018-2021 (n=3489), with increases occurring among all race and ethnicity groups. Direct obstetrical deaths increased from 8.41 in 1999-2002 to 14.1 per 100,000 live births in 2018-2021, whereas indirect obstetrical deaths increased from 1.24 to 9.41 per 100,000 live births: 38% of direct obstetrical deaths and 87% of indirect obstetrical deaths in 2018-2021 were identified because of a positive pregnancy checkbox. The pregnancy checkbox was associated with increases in less specific and incidental causes of death. For example, maternal deaths with malignant neoplasms listed as a multiple cause of death increased 46-fold from 0.03 in 1999-2002 to 1.42 per 100,000 live births in 2018-2021. Under the alternative formulation, the maternal mortality rate was 10.2 in 1999-2002 and 10.4 per 100,000 live births in 2018-2021; deaths from direct obstetrical causes decreased from 7.05 to 5.82 per 100,000 live births. Deaths due to preeclampsia, eclampsia, postpartum hemorrhage, puerperal sepsis, venous complications, and embolism decreased, whereas deaths due to adherent placenta, renal and unspecified causes, cardiomyopathy, and preexisting hypertension increased. Maternal mortality increased among non-Hispanic White women and decreased among non-Hispanic Black and Hispanic women. However, rates were disproportionately higher among non-Hispanic Black women, with large disparities evident in several causes of death (eg, cardiomyopathy). CONCLUSION: The high and rising rates of maternal mortality in the United States are a consequence of changes in maternal mortality surveillance, with reliance on the pregnancy checkbox leading to an increase in misclassified maternal deaths. Identifying maternal deaths by requiring mention of pregnancy among the multiple causes of death shows lower, stable maternal mortality rates and declines in maternal deaths from direct obstetrical causes.

Reducing maternal mortality in low- and middle-income countries: the Nepalese approach of helicopter retrieval.

Ninety-four percent of global maternal deaths occur in low- and middle-income countries (LMICs). The UN has a goal of reducing maternal deaths to <70 per 100,000 live births by 2030, but progress is minimal. Maternal deaths in LMICs are associated with 3 delays in the care of women with obstetrical emergencies: 1) in the family of the woman realizing that her life is at risk, 2) in the transport of the woman to a hospital, and 3) in providing care after arrival at the hospital. These 3 delays function like links in a chain, and failure of any link leads to maternal death. LMICs have characteristics that make it likely that the chain will break. Women in LMICs frequently have low standing, and cultural beliefs often lead to delay in the recognition of obstetrical emergencies. LMICs are characterized by poor roads and long distances to hospitals leading to transport delays. Cultural and other factors also lead to treatment delays when a woman reaches a suitably-equipped and staffed hospital. Nepal has addressed these delays and reduced maternal mortality. Firstly, we have reported in the Journal the use of culturally acceptable approaches to improving the knowledge about antenatal care in remote villages. In the case of Nepal, singing songs related to maternal care proved to be a highly effective strategy. We now report that the government of Nepal has repurposed military helicopters to overcome the tyranny of poor roads to allow rapid transport of women with obstetrical emergencies to a small number of fully-equipped and staffed hospitals. As of June 2023, this service has successfully retrieved 625 women in four and half years. The Nepalese government has included questions on maternal mortality in the 2021 national census, followed by a verbal autopsy. These data indicate a fall in the maternal mortality ratio from 239 in 2016 to 151 in 2021. The efficiency of the triage service continues to improve, suggesting that maternal mortality will continue to fall. This may provide a model that can be implemented in other LMICs and highlights factors that may be responsible for recent increases in the US maternal mortality ratio.

Society for Maternal-Fetal Medicine Position Statement: Extending Medicaid coverage for 12 months postpartum.

Position: The Society for Maternal-Fetal Medicine supports federal and state policies that expand Medicaid eligibility and extend Medicaid coverage through 12 months postpartum to address the maternal morbidity and mortality crisis and improve health equity. Access to coverage is essential to optimize maternal health following pregnancy and childbirth and avoid preventable causes of maternal morbidity and mortality that extend throughout the first year postpartum. The Society opposes policies such as work requirements or limitations on coverage for undocumented individuals that unnecessarily impose restrictions on Medicaid eligibility.

Society for Maternal-Fetal Medicine Consult Series #68: Sickle cell disease in pregnancy.

Pregnant individuals with sickle cell disease have an increased risk of maternal and perinatal morbidity and mortality. However, prepregnancy counseling and multidisciplinary care can lead to favorable maternal and neonatal outcomes. In this consult series, we summarize what is known about sickle cell disease and provide guidance for sickle cell disease management during pregnancy. The following are Society for Maternal-Fetal Medicine recommendations.

Effectiveness of care bundles for prevention and treatment of postpartum hemorrhage: a systematic review.

OBJECTIVE: Care bundles are a promising approach to reducing postpartum hemorrhage-related morbidity and mortality. We assessed the effectiveness and safety of care bundles for postpartum hemorrhage prevention and/or treatment. DATA SOURCES: We searched MEDLINE, Embase, Cochrane CENTRAL, Maternity and Infant Care Database, and Global Index Medicus (inception to June 9, 2023) and ClinicalTrials.gov and the International Clinical Trials Registry Platform (last 5 years) using a phased search strategy, combining terms for postpartum hemorrhage and care bundles. STUDY ELIGIBILITY CRITERIA: Peer-reviewed studies evaluating postpartum hemorrhage-related care bundles were included. Care bundles were defined as interventions comprising ≥3 components implemented collectively, concurrently, or in rapid succession. Randomized and nonrandomized controlled trials, interrupted time series, and before-after studies (controlled or uncontrolled) were eligible. METHODS: Risk of bias was assessed using RoB 2 (randomized trials) and ROBINS-I (nonrandomized studies). For controlled studies, we reported risk ratios for dichotomous outcomes and mean differences for continuous outcomes, with certainty of evidence determined using GRADE. For uncontrolled studies, we used effect direction tables and summarized results narratively. RESULTS: Twenty-two studies were included for analysis. For prevention-only bundles (2 studies), low-certainty evidence suggests possible benefits in reducing blood loss, duration of hospitalization, and intensive care unit stay, and maternal well-being. For treatment-only bundles (9 studies), high-certainty evidence shows that the E-MOTIVE intervention reduced risks of composite severe morbidity (risk ratio, 0.40; 95% confidence interval, 0.32-0.50) and blood transfusion for bleeding, postpartum hemorrhage, severe postpartum hemorrhage, and mean blood loss. One nonrandomized trial and 7 uncontrolled studies suggest that other postpartum hemorrhage treatment bundles might reduce blood loss and severe postpartum hemorrhage, but this is uncertain. For combined prevention/treatment bundles (11 studies), low-certainty evidence shows that the California Maternal Quality Care Collaborative care bundle may reduce severe maternal morbidity (risk ratio, 0.64; 95% confidence interval, 0.57-0.72). Ten uncontrolled studies variably showed possible benefits, no effects, or harms for other bundle types. Nearly all uncontrolled studies did not use suitable statistical methods for single-group pretest-posttest comparisons and should thus be interpreted with caution. CONCLUSION: The E-MOTIVE intervention improves postpartum hemorrhage-related outcomes among women delivering vaginally, and the California Maternal Quality Care Collaborative bundle may reduce severe maternal morbidity. Other bundle designs warrant further effectiveness research before implementation is contemplated.

History of multifetal gestation and long-term maternal mortality.

BACKGROUND: Multifetal gestation could be associated with higher long-term maternal mortality because it increases the risk of pregnancy complications such as preeclampsia and preterm birth, which are in turn linked to postpartum cardiovascular risk. OBJECTIVES: We examined whether spontaneously conceived multifetal versus singleton gestation was associated with long-term maternal mortality in a racially diverse U.S. METHODS: We ascertained vital status as of 2016 via linkage to the National Death Index and Social Security Death Master File of 44,174 mothers from the Collaborative Perinatal Project (CPP; 1959-1966). Cox proportional hazards models with maternal age as the time scale assessed associations between history of spontaneous multifetal gestation (in the last CPP observed pregnancy or prior pregnancy) and all-cause and cardiovascular mortality, adjusted for demographics, smoking status, and preexisting medical conditions. We calculated hazard ratios (HR) for all-cause and cause-specific mortality over the study period and until age 50, 60, and 70 years (premature mortality). RESULTS: Of eligible participants, 1672 (3.8%) had a history of multifetal gestation. Participants with versus without a history of multifetal gestation were older, more likely to have a preexisting condition, and more likely to smoke. By 2016, 51% of participants with and 38% of participants without a history of multifetal gestation had died (unadjusted all-cause HR 1.14, 95% confidence interval [CI] 1.07, 1.23). After adjustment for smoking and preexisting conditions, a history of multifetal gestation was not associated with all-cause (adjusted HR 1.00, 95% CI 0.93, 1.08) or cardiovascular mortality (adjusted HR 0.99, 95% CI 0.87, 1.11) over the study period. However, history of multifetal gestation was associated with an 11% lower risk of premature all-cause mortality (adjusted HR 0.89, 95% CI 0.82, 0.96). CONCLUSIONS: In a cohort with over 50 years of follow-up, history of multifetal gestation was not associated with all-cause mortality, but may be associated with a lower risk of premature mortality.

Burden and outcomes of postpartum haemorrhage in Nigerian referral-level hospitals.

OBJECTIVE: To determine the prevalence of primary postpartum haemorrhage (PPH), risk factors, and maternal and neonatal outcomes in a multicentre study across Nigeria. DESIGN: A secondary data analysis using a cross-sectional design. SETTING: Referral-level hospitals (48 public and six private facilities). POPULATION: Women admitted for birth between 1 September 2019 and 31 August 2020. METHODS: Data collected over a 1-year period from the Maternal and Perinatal Database for Quality, Equity and Dignity programme in Nigeria were analysed, stratified by mode of delivery (vaginal or caesarean), using a mixed-effects logistic regression model. MAIN OUTCOME MEASURES: Prevalence of PPH and maternal and neonatal outcomes. RESULTS: Of 68 754 women, 2169 (3.2%, 95% CI 3.07%-3.30%) had PPH, with a prevalence of 2.7% (95% CI 2.55%-2.85%) and 4.0% (95% CI 3.75%-4.25%) for vaginal and caesarean deliveries, respectively. Factors associated with PPH following vaginal delivery were: no formal education (aOR 2.2, 95% CI 1.8-2.6, P < 0.001); multiple pregnancy (aOR 2.7, 95% CI 2.1-3.5, P < 0.001); and antepartum haemorrhage (aOR 11.7, 95% CI 9.4-14.7, P < 0.001). Factors associated with PPH in a caesarean delivery were: maternal age of >35 years (aOR 1.7, 95% CI 1.5-2.0, P < 0.001); referral from informal setting (aOR 2.4, 95% CI 1.4-4.0, P = 0.002); and antepartum haemorrhage (aOR 3.7, 95% CI 2.8-4.7, P < 0.001). Maternal mortality occurred in 4.8% (104/2169) of deliveries overall, and in 8.5% (101/1182) of intensive care unit admissions. One-quarter of all infants were stillborn (570/2307), representing 23.9% (429/1796) of neonatal intensive care unit admissions. CONCLUSIONS: A PPH prevalence of 3.2% can be reduced with improved access to skilled birth attendants.

Association between pregnancy affected by vaginal bleeding and women's mortality: A cohort study.

OBJECTIVE: To investigate the association between vaginal bleeding (VB) in pregnancy and women's mortality, using VB-unaffected pregnancies, terminations and miscarriages as comparators. DESIGN: Observational cohort study. SETTING: Nationwide registries of Denmark linked at an individual level. POPULATION OR SAMPLE: 1 354 181 women and their 3 162 317 pregnancies (1979-2017), including 70 835 VB-affected pregnancies and comparators: 2 236 359 VB-unaffected pregnancies ending in childbirth; 589 697 terminations; and 265 426 miscarriages. METHODS: We followed pregnancies until the earliest date of woman's death, emigration or end of data. MAIN OUTCOME MEASURES: All-cause and cause-specific mortality rates per 10 000 person-years (PY) and hazard ratios (HRs) with 95% confidence intervals (CIs) adjusted using Cox proportional hazards regression for age, calendar year, pre-existing chronic conditions and socio-economic factors. RESULTS: There were 2320 deaths from any cause among women following VB-affected pregnancy (mortality rate 15.2, 95% CI 14.6-15.9 per 10 000 PY); 55 030 deaths following VB-unaffected pregnancy (mortality rate 12.7, 95% CI 12.6-12.8); 27 500 deaths following a termination (mortality rate 21.9, 95% CI 21.6-22.1), and 10 865 deaths following a miscarriage (mortality rate 19.2, 95% CI 18.8-19.6). For comparison of VB-affected versus VB-unaffected pregnancies, associations with all-cause (HR 1.14, 95% CI 1.09-1.19), natural causes (HR 1.15, 95% CI 1.09-1.22) and non-natural causes (HR 1.27, 95% CI 1.08-1.48) mortality were attenuated in a sensitivity analysis of pregnancies recorded in 1994-2017 (HR 1.00, 95% CI 0.90-1.12, HR 0.98, 95% CI 0.85-1.14 and HR 1.04, 95% CI 0.72-1.51, respectively). Contrasts with remaining comparators did not suggest increased risks of all-cause, natural or non-natural mortality causes. CONCLUSION: We found no evidence of an increased risk of women's mortality following VB-affected versus VB-unaffected pregnancy, termination or miscarriage.

The contribution of suicide to maternal mortality: A nationwide population-based cohort study.

OBJECTIVE: To identify the incidence and characteristics of maternal suicide. DESIGN: Nationwide population-based cohort study. SETTING: The Netherlands, 2006-2020. POPULATION: Women who died during pregnancy or within 1 year postpartum, and a reference population of women aged 25-45 years. METHODS: The Cause of Death Register and Medical Birth Register were linked to identify women who died within 1 year postpartum. Data were combined with deaths reported to the Audit Committee for Maternal Mortality and Morbidity (ACMMM), which performs confidential enquiries. Maternal suicides were compared with a previous period (1996-2005). Risk factors were obtained by combining vital statistics databases. MAIN OUTCOME MEASURES: Comparison of incidence and proportion of maternal suicides among all maternal deaths over time, sociodemographic and patient-related risk factors and underreporting of postpartum suicides. RESULTS: The maternal suicide rate remained stable with 68 deaths: 2.6 per 100 000 live births in 2006-2020 versus 2.5 per 100 000 in 1996-2005. The proportion of suicides among all maternal deaths increased from 18% to 28%. Most suicides occurred throughout the first year postpartum (64/68); 34 (53%) of the women who died by suicide postpartum were primiparous. Compared with mid-level, low educational level was a risk factor (odds ratio 4.2, 95% confidence interval 2.3-7.9). Of 20 women reported to the ACMMM, 11 (55%) had a psychiatric history and 13 (65%) were in psychiatric treatment at the time of death. Underreporting to ACMMM was 78%. CONCLUSIONS: Although the overall maternal mortality ratio declined, maternal suicides did not and are now the leading cause of maternal mortality if late deaths up to 1 year postpartum are included. Data collection and analysis of suicides must improve.

Maternal mortality during war time in Tigray, Ethiopia: A community-based study.

OBJECTIVE: This study seeks to examine the impact of war on maternal mortality following an exacerbation in the dynamics of inequality in maternal health caused by the continuing conflict. DESIGN: Community-based cross-sectional study. SETTING: Tigray region of Northern Ethiopia, between November 2020 and May 2022. POPULATION: This study surveyed a total of 189 087 households from six of the seven zones of Tigray in 121 tabiyas from 31 districts selected. A multistage cluster sampling technique was used to select the districts and tabiyas. METHODS: The study was conducted in two phases. In the first phase, reproductive-age deaths that occurred during the study period were screened. In the second phase, verbal autopsies were conducted at the screened households. MAIN OUTCOME MEASURES: Maternal mortality ratio level and cause-specific mortality. RESULTS: The results of the study showed that the maternal mortality ratio was 840 (95% CI 739-914) per 100 000 live births. Haemorrhage, 107 (42.8%), pregnancy-induced hypertension, 21 (8.4%), and accidents, 14 (5.6%), were the main causes of mortality. Additionally, 203 (81.2%) of the mothers died outside of a health facility. CONCLUSIONS: This study has shown a higher maternal mortality ratio following the dynamics of the Tigray war, as compared with the pre-war level of 186/100 000. Furthermore, potentially many of the pregnancy-related deaths could have been prevented with access to preventive and emergency services. Given the destruction and looting of many facilities, the restoration and improvement of the Tigray health system must take precedence.

Cardiogenic shock in pregnancy.

Cardiac disease complicates 1%-4% of pregnancies globally, with a predominance in low and middle-income countries (LMICs). Increasing maternal age, rates of obesity, cardiovascular comorbidities, pre-eclampsia and gestational diabetes all contribute to acquired cardiovascular disease in pregnancy. Additionally, improved survival in congenital heart disease (CHD) has led to increasing numbers of women with CHD undergoing pregnancy. Implementation of individualised care plans formulated through pre-conception counselling and based on national and international guidance have contributed to improved clinical outcomes. However, there remains a significant proportion of women of reproductive age with no apparent comorbidities or risk factors that develop heart disease during pregnancy, with no indication for pre-conception counselling. The most extreme manifestation of cardiac disease is cardiogenic shock (CS), where the primary cardiac pathology results in inadequate cardiac output and hypoperfusion, and is associated with significant mortality and morbidity. Key to management is early recognition, intervention to treat any potentially reversible underlying pathology and supportive measures, up to and including mechanical circulatory support (MCS). In this narrative review we discuss recent developments in the classification of CS, and how these may be adapted to improve outcomes of pregnant women with, or at risk of developing, this potentially lethal condition.

Persistent inequities in maternal mortality in Latin America and the Caribbean, 1990-2019.

BACKGROUND: Despite the resources and personnel mobilized in Latin America and the Caribbean to reduce the maternal mortality ratio (MMR, maternal deaths per 100 000 live births) in women aged 10-54 years by 75% between 2000 and 2015, the region failed to meet the Millenium Development Goals (MDGs) due to persistent barriers to access quality reproductive, maternal, and neonatal health services. METHODS: Using 1990-2019 data from the Global Burden of Disease project, we carried out a two-stepwise analysis to (a) identify the differences in the MMR temporal patterns and (b) assess its relationship with selected indicators: government health expenditure (GHE), the GHE as percentage of gross domestic product (GDP), the availability of human resources for health (HRH), the coverage of effective interventions to reduce maternal mortality, and the level of economic development of each country. FINDINGS: In the descriptive analysis, we observed a heterogeneous overall reduction of MMR in the region between 1990 and 2019 and heterogeneous overall increases in the GHE, GHE/GDP, and HRH availability. The correlation analysis showed a close, negative, and dependent association of the economic development level between the MMR and GHE per capita, the percentage of GHE to GDP, the availability of HRH, and the coverage of SBA. We observed the lowest MMRs when GHE as a percentage of GDP was close to 3% or about US$400 GHE per capita, HRH availability of 6 doctors, nurses, and midwives per 1,000 inhabitants, and skilled birth attendance levels above 90%. CONCLUSIONS: Within the framework of the Sustainable Development Goals (SDGs) agenda, health policies aimed at the effective reduction of maternal mortality should consider allocating more resources as a necessary but not sufficient condition to achieve the goals and should prioritize the implementation of new forms of care with a gender and rights approach, as well as strengthening actions focused on vulnerable groups.

A population-based estimation of maternal mortality in Lagos State, Nigeria using the indirect sisterhood method.

BACKGROUND: Pregnancy and delivery deaths represent a risk to women, particularly those living in low- and middle-income countries (LMICs). This population-based survey was conducted to provide estimates of the maternal mortality ratio (MMR) in Lagos Nigeria. METHODS: A community-based, cross-sectional study was conducted in mapped Wards and Enumeration Areas (EA) of all Local Government Areas (LGAs) in Lagos, among 9,986 women of reproductive age (15-49 years) from April to August 2022 using a 2-stage cluster sampling technique. A semi-structured, pre-tested questionnaire adapted from nationally representative surveys was administered using REDCap by trained field assistants for data collection on socio-demographics, reproductive health, fertility, and maternal mortality. Data were analysed using SPSS and MMR was estimated using the indirect sisterhood method. Ethical approval was obtained from the Lagos State University Teaching Hospital Health Research and Ethics Committee. RESULTS: Most of the respondents (28.7%) were aged 25-29 years. Out of 546 deceased sisters reported, 120 (22%) died from maternal causes. Sisters of the deceased aged 20-24 reported almost half of the deaths (46.7%) as due to maternal causes, while those aged 45-49 reported the highest number of deceased sisters who died from other causes (90.2%). The total fertility rate (TFR) was calculated as 3.807, the Lifetime Risk (LTR) of maternal death was 0.0196 or 1-in-51, and the MMR was 430 per 100,000 [95% CI: 360-510]. CONCLUSION: Our findings show that the maternal mortality rate for Lagos remains unacceptable and has not changed significantly over time in actual terms. There is need to develop and intensify community-based intervention strategies, programs for private hospitals, monitor MMR trends, identify and contextually address barriers at all levels of maternal care.

Adverse maternal outcomes and associated factors among mothers of advanced age delivering at a tertiary hospital, southwestern Uganda: a cross-sectional study.

BACKGROUND: Mothers of advanced age, defined as pregnant women aged ≥ 35 years at the time of giving birth, are traditionally known to be associated with increased risks of adverse maternal outcomes. We determined the prevalence of adverse maternal outcomes and associated factors among mothers of advanced age who delivered at Kabale Regional Referral Hospital (KRRH), in Southwestern Uganda. METHODS: We conducted a cross-sectional study at the Maternity Ward of KRRH from April to September 2023. We consecutively enrolled pregnant women aged ≥ 35 years during their immediate post-delivery period and before discharge. We obtained data on their socio-demographic, obstetric, medical characteristics and their maternal outcomes using interviewer-administered questionnaires. We defined adverse maternal outcome as any complication sustained by the mother that was related to pregnancy, delivery and immediate post-partum events (obstructed labour, antepartum haemorrhage, mode of delivery [cesarean or vacuum extraction], postpartum haemorrhage, hypertensive disorders of pregnancy, preterm or postdate pregnancy, anemia, premature rupture of membranes, multiple pregnancy, and maternal death). A participant was considered to have an adverse outcome if they experienced any one of these complications. We identified factors associated with adverse outcomes using modified Poisson regression. RESULTS: Out of 417 participants, most were aged 35-37 years (n = 206; 49.4%), and had parity ≥ 5 (65.5%). The prevalence of adverse maternal outcomes was 37.6% (n = 157, 95%CI: 33.1-42.4%). Common adverse maternal outcomes included caesarian delivery (23%), and obstructed labour (14.4%). Other complications included anemia in pregnancy (4.5%), chorioamnionitis (4.1%), preterm prelabour rupture of membranes (3.9%), and chronic hypertension and preeclampsia (both 2.4%). Factors associated with adverse maternal outcomes were precipitate labour (adjusted prevalence ratio [aPR] = 1.95, 95%CI: 1.44-2.65), prolonged labour, lasting > 12 h (aPR = 2.86, 95%CI: 1.48-3.16), and chronic hypertension (aPR = 2.01, 95%CI: 1.34-3.9). CONCLUSION: Approximately two-fifth of the advanced-aged mothers surveyed had adverse outcomes. Mothers with prolonged labour, precipitate labour and chronic hypertension were more likely to experience adverse outcomes. We recommend implementation of targeted interventions, emphasizing proper management of labor as well as close monitoring of hypertensive mothers, and those with precipitate or prolonged labor, to mitigate risks of adverse outcomes within this study population.

Standards of care and determinants of women's satisfaction with delivery services in Nepal: a multi-perspective analysis using data from a health facility-based survey.

BACKGROUND: Compliance with standards of care is required for sustained improvement in the quality of delivery services. It thus represents a key challenge to improving maternal survival and meeting the Sustainable Development Goal (SDG) target of reducing the maternal mortality ratio to 70 deaths per 100,000 live births. This study examines the extent to which normal low-risk health facility deliveries in Nepal meet the standards of quality of care and assesses the effect of the standards of quality of care and various contextual factors on women's satisfaction with the services they receive. METHODS: Drawing on the 2021 Nepal Health Facility Survey, the sample comprised 320 women who used health facilities for normal, low-risk delivery services. A weighted one-sample t-test was applied to examine the proportion of deliveries meeting the eight standards of care. Women's overall satisfaction level was computed from seven satisfaction variables measured on a Likert scale, using principal component analysis. The composite measure was then dichotomized. Binary logistic regression was used to analyze the determinants of women's satisfaction with delivery care services. RESULTS: Deliveries complying with the eight standards of care and its 53 indicators varied widely; output indicators were more frequently met than input indicators. Of the eight standards of care, the "functional referral system" performed highest (92.0%), while "competent, motivated human resources" performed the least (52.4%). Women who were attended by a provider when they called for support (AOR: 5.29; CI: 1.18, 23.64), who delivered in health facilities that displayed health statistics (AOR 3.16; CI: 1.87, 5.33), who experienced caring behaviors from providers (AOR: 2.59; CI: 1.06, 6.30) and who enjoyed audio-visual privacy (AOR 2.13; CI: 1.04, 4.38) had higher satisfaction levels compared to their counterparts. The implementation of the Maternity Incentive Scheme and presence of a maternal waiting room in health facilities, however, were associated with lower satisfaction levels. CONCLUSIONS: Nepal performed moderately well in meeting the standards of care for normal, low-risk deliveries. To meet the SDG target Nepal must accelerate progress. It needs to focus on people-centered quality improvement to routinely assess the standards of care, mobilize available resources, improve coordination among the three tiers of government, and implement high-impact programs.
