An evidence map for social and structural determinants for maternal morbidity and mortality: a systematic review.
The study aimed to identify social and structural determinants of maternal morbidity and mortality during prenatal and postpartum periods in the U.S. Out of 8,378 references screened, 118 studies were included, covering domains like identity, socioeconomic factors, violence, and trauma. Findings revealed mixed patterns between risk factors and outcomes, with notable attention to depression and mental health. Advancing the field long-term should involve developing comprehensive datasets to thoroughly investigate intersections with biological and medical risk factors.

Effects of the COVID-19 early pandemic on delivery outcomes among women with and without COVID-19 at birth.
This AHRQ-authored paper examined the early pandemic-related changes in birth outcomes for pregnant women with and without a COVID-19 diagnosis at delivery. They compared four delivery outcomes-preterm delivery (PTD), severe maternal morbidity (SMM), stillbirth, and cesarean birth-between 2017 and 2019 (prepandemic) and between April and December 2020 (early pandemic) using interrupted time series models on 11.8 million deliveries, stratified by COVID-19 infection status at birth with entropy weighting for historical controls, from the HCUP across 43 states and the District of Columbia. Relative to 2017-2019, women without COVID-19 at delivery in 2020 had lower odds of PTD (OR = 0.93) and SMM (OR = 0.88) but increased odds of stillbirth (OR = 1.04). COVID-19 deliveries had an excess of each outcome, by factors of 1.07-1.46 for outcomes except SMM at 4.21. The effect for SMM was more pronounced for Asian/Pacific Islander non-Hispanic (API; OR = 10.51) and Hispanic (OR = 5.09) pregnant women than for White non-Hispanic (OR = 3.28) women.

Development of a composite risk index of reproductive autonomy using state laws: association with maternal and neonatal outcomes.
This study investigated whether greater reproductive autonomy would be associated with lower rates of severe maternal morbidity (SMM), pregnancy-related mortality (PRM), preterm birth (PTB), and low birthweight. It was hypothesized that greater reproductive autonomy would lower the risks of poor maternal and neonatal outcomes. The authors developed a composite index to quantify state legislation, which was used to examine the association with maternal and neonatal outcomes. A Delphi panel was used to inform index development, and restrictive policies were assigned values of -1 and enabling policies +1. Publicly available data was used to conduct a cross-sectional study of all live births in the 50 US states for people ages 15 to 44 from 2016 to 2018 to examine the association between the risk index and PRM, SMM, PTB, and low birthweight. There were 11,530,785 births, 2,846 pregnancy-related deaths, and 154,384 cases of SMM from 2016 to 2018. The Delphi panel found a summed state measure of 106 laws in 8 categories that could affect reproductive anatomy. In adjusted analyses, states in the most enabling reproductive autonomy quartile had a 44.7 per 10,000 higher rate of SMM compared with the most restrictive quartile. However, the most enabling quartile was associated with a 9.87 per 100,000 lower rate of PRM and 0.67 per 100 lower rate of PTB compared with the most restrictive quartile.

Reduced compared with traditional schedules for routine antenatal visits: a systematic review.
This systematic review’s objective was to assess differences in maternal and child outcomes in studies comparing reduced routine antenatal visit schedules with traditional schedules. The search was conducted in multiple databases searching for antenatal (prenatal) care, pregnancy, obstetrics, telemedicine, remote care, smartphones, telemonitoring, and related terms. Abstrackr was used for double independent screening for studies comparing televisits and in person routine antenatal care visits for maternal, child, health care utilization, and harm outcomes. The authors found five randomized controlled trials and five nonrandomized comparative studies that compared reduced routine antenatal visit schedules with traditional schedules. The studies did not find differences between schedules in gestational age at birth, likelihood of being small for gestational age, likelihood of a low Apgar score, likelihood of neonatal intensive care unit admission, maternal anxiety, likelihood of preterm birth, and likelihood of low birth weight. There was also insufficient evidence for numerous prioritized outcomes of interest, including completion of the American College of Obstetricians and Gynecologists-recommended services and patient experience measures.

Pregnancy outcomes in a US cohort of transgender people.
This letter summarized a study which assessed severe parental morbidity, cesarean deliveries, and preterm births among trans people compared with cisgender people. Data on deliveries was taken the Truven MarketScan Medicaid and commercial databases separately. Results indicated that trans individuals had similar rates of severe parental morbidity as cisgender people. Rates of cesarean delivery were significantly lower among trans people. No significant difference were found in preterm birth rates.

Health insurance coverage and postpartum outcomes in the US: a systematic review.
The objective of this evidence review was to assess whether extension of health insurance coverage or improvements in health care access are associated with postpartum health care utilization and maternal outcomes. Findings with moderate strength of evidence suggested that more comprehensive association was likely to be related to greater postpartum visit attendance; findings with low strength of evidence indicated a possible association between more comprehensive insurance, fewer preventable readmissions, and emergency department visits. The authors concluded that these findings suggested that evidence evaluating insurance coverage and postpartum visit attendance and unplanned care utilization is, at best, of moderate strength of evidence. They recommended that future research should evaluate clinical outcomes associated with more comprehensive insurance coverage.

Adverse maternal and delivery outcomes in children and very young (age ≤13 years) US adolescents compared with older adolescents and adults.
This study compared adverse maternal and delivery outcomes of pregnant 10- to 13-year-olds vs 14- to 17-year-olds and 18- to 19-year-olds. This cross-sectional study looked at all patients aged 10 to 19 years who delivered at hospitals in the Premier Healthcare Database from January 2019 through May 2021. The study included 90,876 deliveries across 655 US hospitals. Controlling for patient race and ethnicity, insurance type, and obesity status: 10- to 13-year-olds had significantly higher risks of preterm delivery and cesarean delivery compared with 14- to 17-year-olds. The risk of preeclampsia was not higher for 10- to 13-year-olds compared to 14- to 17-year-olds. There was a higher risk of preterm delivery for 10- to 13-year-olds compared to 18- to 19-year-olds, but not significantly different for cesarean delivery and preeclampsia.

Maternal, infant, and child health outcomes associated with the Special Supplemental Nutrition Program for Women, Infants, and Children: a systematic review.
The purpose of this study was to determine whether WIC participation was associated with improved maternal, neonatal-birth, and infant-child health outcomes or differences in outcomes by subgroups and WIC enrollment duration. Findings showed moderate strength of evidence (SOE) that maternal WIC participation during pregnancy is likely associated with lower risk for preterm birth, low birthweight infants, and infant mortality; low SOE that maternal WIC participation may be associated with a lower likelihood of inadequate gestational weight gain, as well as increased well-child visits and childhood immunizations; and low SOE that child WIC participation may be associated with increased childhood immunizations. Further, findings showed low SOE for differences in some outcomes by race and ethnicity but insufficient evidence for differences by WIC enrollment duration.

Trial of labor after two prior cesarean deliveries: patient and hospital characteristics and birth outcomes.
This study’s goal was to examine utilization, success rate, and maternal and neonatal outcomes of trial of labor among women with two prior cesarean deliveries. Linked hospital discharge and birth certificate data were used for a retrospective analyses of a cohort of women in California with nonanomalous, term, singleton live births, two prior cesarean deliveries, and no clear contraindications for trial of labor. Findings showed that, among women with two prior cesarean deliveries, trial of labor was rarely attempted and was successful in 39.4% of attempts. Trial of labor in this population was associated with a modest increase in severe neonatal morbidity.

Midwifery presence in United States medical centers and labor care and birth outcomes among low-risk nulliparous women: a Consortium on Safe Labor study.
This study compared labor care and birth outcomes between medical centers with interprofessional care (midwives and physicians) versus noninterprofessional care (physicians only). A retrospective cohort study was conducted using Consortium on Safe labor data from low-risk nulliparous women who birthed in interprofessional (7393) or noninterprofessional (6982). Women at interprofessional medical centers were 74% less likely to undergo labor induction and 75% less likely to have oxytocin augmentation. In addition, the cesarean rate was 12% lower.

Influence of midwifery presence in United States centers on labor care and outcomes of low-risk parous women: a Consortium on Safe Labor study.
The authors analyzed the association between midwifery presence in maternity care teams and the birth processes and outcomes of low-risk parous women. They found that parous women have significantly higher rates of vaginal birth, including vaginal birth after cesarean, and a lower likelihood of labor induction when cared for in centers with midwives. They concluded that their findings support integrated, team-based models of perinatal care to improve maternal outcomes.

Associations between hospital maternal service level and delivery outcomes.
This study explored the associations between delivery hospital self-reported level of maternal service, as defined by the American Hospital Association, and both maternal and neonatal outcomes among women at high maternal risk, as defined by the Obstetric Comorbidity Index. The investigators concluded that for the group of pregnant women in need of maternal transfer, delivery hospital self-reported level of maternal care was not associated with the odds of poor maternal or neonatal outcomes.

Impact of the Agency for Healthcare Research and Quality's Safety Program for Perinatal Care.
The purpose of this study was to describe the Safety Program for Perinatal Care (SPPC) implementation experience and evaluate the short-term impact on labor and delivery (L&D) unit patient safety culture, processes, and adverse events. SPPC implementation by L&D units were supported sing a program toolkit, trainings, and technical assistance. Researchers then evaluated the program using a pre-post, mixed-methods design. Changes in safety and quality were measured using the Modified Adverse Outcome Index (MAOI) and other perinatal care indicators. Findings showed that SPPC had a favorable impact on unit patient safety culture and processes, but mixed short-term impact on maternal and neonatal adverse events.

Validity of maternal and infant outcomes within nationwide Medicaid data.
The researchers aimed to assess the validity of preeclampsia, congenital cardiac malformations, and persistent pulmonary hypertension of the newborn diagnoses in the U.S. Medicaid Analytic eXtract (MAX), a database that may be useful for perinatal research. The positive predictive values were conservative, particularly when restricting to infants not transferred to another facility shortly after birth because only records from a single hospitalization were reviewed.
