BACKGROUND: The World Health Organization (WHO) published the WHO Safe Childbirth Checklist in 2015, which included the key evidence-based practices to prevent the major causes of maternal and neonatal morbidity and mortality during childbirth. We assessed the current use of the WHO Safe Childbirth Checklist (SCC) and adaptations regarding the SCC tool and implementation strategies in different contexts from Africa, Southeast Asia, Europe, and North America.

METHODS: This explanatory, sequential mixed methods study-including surveys followed by interviews-of global SCC implementers focused on adaptation and implementation strategies, data collection, and desired improvements to support ongoing SCC use. We analyzed the survey results using descriptive statistics. In a subset of respondents, follow-up virtual semi-structured interviews explored how they adapted, implemented, and evaluated the SCC in their context. We used rapid inductive and deductive thematic analysis for the interviews.

RESULTS: Of the 483 total potential participants, 65 (13.5%) responded to the survey; 55 completed the survey (11.4%). We analyzed completed responses from those who identified as having SCC implementation experience (n = 29, 52.7%). Twelve interviews were conducted and analyzed. Ninety percent of respondents indicated that they adapted the SCC tool, including adding clinical and operational items. Adaptations to structure included translation into local language, incorporation into a mobile app, and integration into medical records. Respondents reported variation in implementation strategies and data collection. The most common implementation strategies were meeting with stakeholders to secure buy-in, incorporating technical training, and providing supportive supervision or coaching around SCC use. Desired improvements included clarifying the purpose of the SCC, adding guidance on relevant clinical topics, refining items addressing behaviors with low adherence, and integrating contextual factors into decision-making. To improve implementation, participants desired political support to embed SCC into existing policies and ongoing clinical training and coaching.

CONCLUSION: Additional adaptation and implementation guidance for the SCC would be helpful for stakeholders to sustain effective implementation.

OBJECTIVES: While some medical indications for cesarean delivery are clear, subjective provider and patient factors contribute to the rising cesarean delivery rates and marked disparities between racial/ethnic groups. We aimed to determine the association between language preference and risk of primary cesarean delivery.

METHODS: We conducted a retrospective cohort study of nulliparous, term, singleton, vertex (NTSV) deliveries of patients over 18 years old from 2011-2016 at an academic medical center, supplemented with data from the Massachusetts Department of Public Health. We used modified Poisson regression with robust error variance to calculate risk ratios for cesarean delivery between patients with English language preference and other language preference, with secondary outcomes of Apgar score, maternal readmission, blood transfusion, and NICU admission.

RESULTS: Of the 11,298 patients included, 10.3% reported a preferred language other than English, including Mandarin and Cantonese (61.7%), Portuguese (9.7%), and Spanish (7.5%). The adjusted risk ratio for cesarean delivery among patients with a language preference other than English was 0.85 (95% CI 0.72-0.997; p = 0.046) compared to patients with English language preference. No significant differences in risk of secondary outcomes between English and other language preference were found.

DISCUSSION: After adjusting for confounders, this analysis demonstrates a decreased risk of cesarean delivery among women who do not have an English language preference at one institution. This disparity in cesarean delivery rates in an NTSV population warrants future research, raising the question of what clinical and social factors may be contributing to these lower cesarean delivery rates.

BACKGROUND: Low birthweight (LBW) (< 2500 g) is a significant determinant of infant morbidity and mortality worldwide. In low-income settings, the quality of birthweight data suffers from measurement and recording errors, inconsistent data reporting systems, and missing data from non-facility births. This paper describes birthweight data quality and the prevalence of LBW before and after implementation of a birthweight quality improvement (QI) initiative in Amhara region, Ethiopia.

METHODS: A comparative pre-post study was performed in selected rural health facilities located in West Gojjam and South Gondar zones. At baseline, a retrospective review of delivery records from February to May 2018 was performed in 14 health centers to collect birthweight data. A birthweight QI initiative was introduced in August 2019, which included provision of high-quality digital infant weight scales (precision 5 g), routine calibration, training in birth weighing and data recording, and routine field supervision. After the QI implementation, birthweight data were prospectively collected from late August to early September 2019, and December 2019 to June 2020. Data quality, as measured by heaping (weights at exact multiples of 500 g) and rounding to the nearest 100 g, and the prevalence of LBW were calculated before and after QI implementation.

RESULTS: We retrospectively reviewed 1383 delivery records before the QI implementation and prospectively measured 1371 newborn weights after QI implementation. Heaping was most frequently observed at 3000 g and declined from 26% pre-initiative to 6.7% post-initiative. Heaping at 2500 g decreased from 5.4% pre-QI to 2.2% post-QI. The percentage of rounding to the nearest 100 g was reduced from 100% pre-initiative to 36.5% post-initiative. Before the QI initiative, the prevalence of recognized LBW was 2.2% (95% confidence interval [CI]: 1.5-3.1) and after the QI initiative increased to 11.7% (95% CI: 10.1-13.5).

CONCLUSIONS: A QI intervention can improve the quality of birthweight measurements, and data measurement quality may substantially affect estimates of LBW prevalence.

OBJECTIVE: To understand the prevalence of intrapartum oxytocin use, assess associated perinatal and maternal outcomes, and evaluate the impact of a WHO Safe Childbirth Checklist intervention on oxytocin use at primary-level facilities in Uttar Pradesh, India.

DESIGN: Secondary analysis of a cluster-randomised controlled trial.

SETTING: Thirty Primary and Community public health facilities in Uttar Pradesh, India from 2014 to 2017.

POPULATION: Women admitted to a study facility for childbirth at baseline, 2, 6 or 12 months after intervention initiation.

METHODS: The BetterBirth intervention aimed to increase adherence to the WHO Safe Childbirth Checklist. We used Rao-Scott Chi-square tests to compare (1) timing of oxytocin use between study arms and (2) perinatal mortality and resuscitation of infants whose mothers received intrapartum oxytocin versus who did not.

MAIN OUTCOME MEASURES: Intrapartum and postpartum oxytocin administration, perinatal mortality, use of neonatal bag and mask.

RESULTS: We observed 5484 deliveries. At baseline, intrapartum oxytocin was administered to 78.2% of women. Two months after intervention initiation, intrapartum oxytocin (I) was administered to 32.1% of women compared with 70.6% in the control (C) (P < 0.01); this difference diminished after the end of the intervention (I = 48.2%, C = 74.7%, P = 0.03). Partograph use remained at <1% at all facilities. Resuscitation was performed on 7.5% of infants whose mother received intrapartum oxytocin versus 2.0% who did not (P < 0.0001).

CONCLUSIONS: In this setting, intrapartum oxytocin use was high despite limited maternal/fetal monitoring or caesarean capability, and was associated with increased neonatal resuscitation. The BetterBirth intervention was successful at decreasing intrapartum oxytocin use. Ongoing support is needed to sustain these practices.

TWEETABLE ABSTRACT: Coaching + WHO Safe Childbirth Checklist reduces intrapartum oxytocin use and need for newborn resuscitation.

BACKGROUND: The BetterBirth trial tested the effect of a peer coaching program around the WHO Safe Childbirth Checklist for birth attendants in primary-level facilities in Uttar Pradesh, India on a composite measure of perinatal and maternal mortality and maternal morbidity. This study aimed to examine the adherence to essential birth practices between two different cadres of birth attendants-nurses and auxiliary nurse midwives (ANMs)-during and after a peer coaching intervention for the WHO Safe Childbirth Checklist.

METHODS: This is a secondary analysis of birth attendant characteristics, coaching visits, and behavior uptake during the BetterBirth trial through birth attendant surveys, coach observations, and independent observations. Descriptive statistics were calculated overall, and by staffing cadre (staff nurses and ANMs) for demographic characteristics. Logistic regression using the Pearson overdispersion correction (to account for clustering by site) was used to assess differences between staff nurses and ANMs in the intervention group during regular coaching (2-month time point) and 4 months after the coaching program ended (12-month time point).

RESULTS: Of the 570 birth attendants who responded to the survey in intervention and control arms, 474 were staff nurses (83.2%) and 96 were ANMs (16.8%). In the intervention arm, more staff nurses (240/260, 92.3%) received coaching at all pause points compared to ANMs (40/53, 75.5%). At baseline, adherence to practices was similar between ANMs and staff nurses (  30%). Overall percent adherence to essential birth practices among ANMs and nurses was highest at 2 months after intervention initiation, when frequent coaching visits occurred (68.1% and 64.1%, respectively, p = 0.76). Practice adherence tapered to 49.2% among ANMs and 56.1% among staff nurses at 12 months, which was 4 months after coaching had ended (p = 0.68).

CONCLUSIONS: Overall, ANMs and nurses responded similarly to the coaching intervention with the greatest increase in percent adherence to essential birth practices after 2 months of coaching and subsequent decrease in adherence 4 months after coaching ended. While coaching is an effective strategy to support some aspects of birth attendant competency, the structure, content, and frequency of coaching may need to be customized according to the birth attendant training and competency.

Compared to other Mexican states, Chiapas possessed the lowest rate of contraception use among women 15-49 years old (44.6%) in 2018. This convergent mixed-methods study assessed family planning use, perceptions, and decision-making processes among women and men in rural communities where Compañeros En Salud (CES) works in Chiapas, Mexico. We conducted surveys of reproductive-aged women and semi-structured interviews with reproductive-aged women, men, and physicians completing their social-service year in CES communities from 2016 to 2017. Of the 625 survey respondents, 368 (58.9%) reported using contraception. The most common methods were female sterilization (27.7%), bimonthly injection (10.9%), and the implant (10.9%). Interviews were completed with 27 women, 24 men, and 5 physicians and analyzed through an inductive approach. Common reasons for contraception use were preventing pregnancy, lack of resources for additional children, and birth spacing. Adverse effects, influence of male partners, and perceived lack of need emerged as reasons for non-use. Male partners often made the final decision about contraceptive use, while women often chose what method. Physicians reported adverse effects, misconceptions about methods, and lack of women's autonomy as barriers to contraception use. Given misconceptions about contraception methods and the dominant role of men in contraception decision-making, our study illustrates the importance of effective counseling and equitable gender dynamics for family planning programming in rural Chiapas.

OBJECTIVE: To examine racial inequities in low-risk and high-risk (or "medically appropriate") cesarean delivery rates in New Jersey during the era surrounding the United States cesarean surge and peak.

STUDY SETTING AND DESIGN: This retrospective repeated cross-sectional study examined the universe of childbirth hospitalizations in New Jersey from January 1, 2000 through September 30, 2015. We estimate the likelihood of cesarean delivery by maternal race and ethnicity, with mixed-level logistic regression models, stratified by cesarean risk level designated by the Society of Maternal Fetal Medicine (SMFM).

DATA SOURCES AND ANALYTIC SAMPLE: We used all-payer hospital discharge data from the Healthcare Cost and Utilization Project's State Inpatient Discharge Database and linked this data to the American Hospital Association Annual Survey. ZIP-code Tabulation Area (ZCTA)-level racialized economic segregation index data were from the 2007-2011 American Community Survey. We identified 1,604,976 statewide childbirth hospitalizations using International Classification of Diseases-9-CM (ICD-9) diagnosis and procedure codes and Diagnosis-Related Group codes, and created an indicator of cesarean delivery using ICD-9 codes.

PRINCIPAL FINDINGS: Among low-risk deliveries, Black patients, particularly those in the age group of 35-39 years, had higher predicted probabilities of giving birth via cesarean than White people in the same age categories (Black-adjusted predicted probability = 24.0%; vs. White-adjusted predicted probability = 17.3%). Among high-risk deliveries, Black patients aged 35 to 39 years had a lower predicted probability (by 2.7 percentage points) of giving birth via cesarean compared with their White counterparts.

CONCLUSIONS: This study uncovered a lack of medically appropriate cesarean delivery for Black patients, with low-risk Black patients at higher odds of cesarean delivery and high-risk Black patients at lower odds of cesarean than their White counterparts. The significant Black-White inequities highlight the need to address misalignment of evidence-based cesarean delivery practice in the efforts to improve maternal health equity. Quality metrics that track whether cesareans are provided when medically needed may contribute to clinical and policy efforts to prevent disproportionate maternal morbidity and mortality among Black patients.

OBJECTIVE: To measure the association between restricted abortion access and maternal and infant health by maternal nativity (whether they were born in the US).

DESIGN: Observational population-based retrospective cohort study.

SETTING: United States.

POPULATION: All births (N = 33 663 837) in the United States from 2011 to 2019.

METHODS: We use Centers for Disease Control and Prevention (CDC) Period Linked Birth/Infant Deaths datafiles, with a dataset of state-level abortion restrictions (Targeted Restrictions on Abortion Providers (TRAP) laws) to estimate the association between restricted abortion access and maternal and infant health by maternal nativity. We examine restricted abortion access and maternal nativity in a triple-differences framework.

MAIN OUTCOMES MEASURES: The primary outcome we examine is maternal morbidity (defined by the CDC as any delivery involving third- or fourth- degree perineal laceration, ruptured uterus, unplanned hysterectomy, or maternal admission to intensive care). We also explore several secondary factors associated with maternal and infant health (birth interval, birth weight, receiving care in the first trimester, and gestational age at birth).

RESULTS: While we find no impact of TRAP laws on non-immigrants, foreign-born individuals in states with TRAP laws have 15% higher odds of maternal morbidity (aOR = 1.15; CI = 1.00-1.31) compared to US-born individuals in states without TRAP laws.

CONCLUSIONS: Anti-abortion legislation can worsen existing inequalities in maternal and infant health. These findings underscore the urgent need for policies that ensure equitable access to reproductive healthcare for immigrant populations.

IMPORTANCE: The US has the highest rate of preganncy-related death among high-income countries, and disparities continue to widen despite many of these deaths being largely preventable.

OBJECTIVE: To examine the age-standardized national rates of pregnancy-related death from 2018 to 2022 in the US, stratified by cause, and to compare the rates across state and race and ethnicity.

DESIGN, SETTING, AND PARTICIPANTS: This serial cross-sectional study used nationwide data on births and pregnancy-related deaths from the Centers for Disease Control and Prevention's Wide-Ranging Online Data for Epidemiologic Research. All pregnancy-related deaths among women aged 15 to 54 years from 2018 to 2022 were included.

EXPOSURE: State, race and ethnicity, and age.

MAIN OUTCOMES AND MEASURES: The primary outcomes were all-cause and cause-specific maternal death and late maternal death (ie, deaths occurring >42 days and up to 1 year after pregnancy). The age-standardized annual and aggregated rate of pregnancy-related mortality (ASR) was estimated by age group and race and ethnicity, and state-specific crude pregnancy-related mortality rates per 100 000 live births and 95% CIs were calculated.

RESULTS: During 2018 to 2022, there were 6283 pregnancy-related deaths, including 1891 late maternal deaths. The ASR increased by 27.7% from 25.3 deaths per 100 000 live births (95% CI, 23.7-26.9) in 2018 to 32.6 deaths per 100 000 live births (95% CI, 31.2-34.8) in 2022. The increase was observed across age group and was disproportionately driven by deaths that occurred among women aged 25 to 39 years (by 36.8%, 2018 vs 2022). There was a considerable variation in rates by state, ranging from 18.5 to 59.7 deaths per 100 000 live births. If the national rate was reduced to the lowest state rate, 2679 pregnancy-related deaths could have been prevented in 2018 to 2022. American Indian and Alaska Native women had the highest ASR (106.3 deaths per 100 000 live births), followed by non-Hispanic Black women (76.9 deaths per 100 000 live births). Although cardiovascular disease was the leading cause of the overall pregnancy-related deaths, cancer, mental and behavior disorders, and drug-induced and alcohol-induced death were important contributing causes of late maternal death.

CONCLUSIONS AND RELEVANCE: In this cross-sectional analysis of pregnancy-related deaths in the US, rates increased during 2018 to 2022, with large variations by state and race and ethnicity. The concerning rates in the US should be an urgent public health priority.
