Severe maternal morbidity and mortality risk at the intersection of rurality, race and ethnicity, and Medicaid.
Using maternal discharge records from childbirth hospitalizations in the HCUP National Inpatient Sample, 2007-15, researchers examined differences in rates of severe maternal morbidity and mortality by rural or urban geography, race and ethnicity, and clinical factors among Medicaid-funded births and privately insured hospital births. The highest rate of severe maternal morbidity and mortality occurred among rural Indigenous Medicaid-funded births; births among Black rural and urban residents and among Hispanic urban residents also experienced elevated rates. The researchers concluded that heightened rates of severe maternal morbidity and mortality among Medicaid-funded births indicate an opportunity for state and federal policy responses to address the maternal health challenges faced by Medicaid beneficiaries, including Black, Indigenous, and rural residents

Preeclampsia predicts risk of hospitalization for heart failure with preserved ejection fraction.
Preeclampsia is associated with increased risk of future heart failure (HF), but the relationship between preeclampsia and HF subtypes are not well-established. The objective of this analysis was to identify the risk of HF with preserved ejection fraction (HFpEF) following a delivery complicated by preeclampsia/eclampsia. The investigators concluded that preeclampsia/eclampsia was an independent risk factor for future hospitalizations for HFpEF.

The association between preterm birth and postpartum mental healthcare utilization among California birthing people.
This study’s objective was to determine whether preterm birth is associated with postpartum inpatient and emergency mental healthcare utilization. The study sample was taken from a database of live-born neonates delivered in California, 2011-2017, and included all births to singleton infants between the gestational ages of 20 and 44 weeks. The findings indicate found that preterm birth is an independent risk factor for postpartum mental healthcare utilization. These findings suggest that screening for and providing mental health resources to birthing people after delivery are crucial, particularly among people giving birth to preterm infants, regardless of mental health history.

Adverse birth outcomes among women of advanced maternal age with and without health conditions in Maryland.
This study examined the association between advanced maternal age (AMA) and adverse birth outcomes among women with and without preexisting and pregnancy-related health conditions. Data for singleton births from the population-based Maryland Pregnancy Risk Assessment Monitoring System 2004-2015 were used to compare women aged 20-34 years and 35 years and older. Findings indicated that AMA is associated with adverse birth outcomes among women with and without health conditions compared with younger women with similar health status. Recommendations included improved screening and management of health conditions during pregnancy for older women, regardless of parity.

Identifying optimal labor and delivery nurse staffing: the case of cesarean births and nursing hours.
Numerous studies have identified a relationship between nurse staffing and adverse patient outcomes in medical / surgical patient populations. However, little is known about the impact of labor and delivery (L&D) nurse staffing and adverse birth outcomes, such as unintended cesarean delivery, in low-risk term-gestation women. In this study the investigators examined nurse staffing patterns on the likelihood of cesarean sections (C-sections) among low- risk, full gestation births and provided a testing framework to distinguish optimal from ineffective levels of nurse staffing.

Exposure to general anesthesia for cesarean delivery and odds of severe postpartum depression requiring hospitalization.
This retrospective cohort study evaluated the risk of general anesthesia use in cesarean delivery versus neuraxial anesthesia on maternal mental health. Cesarean deliveries performed in New York State hospitals between 2006 and 2013 were included. Exclusion criteria included having more than 1 cesarean delivery during the study period, residing outside of New York State, and having a general anesthetic for other surgery or delivery in the year before or after the index case. The primary outcome looked at was severe postpartum depression (PPD), and secondary outcomes were suicidal ideation, anxiety disorders, and posttraumatic stress disorder (PTSD). The majority of cesareans used neuraxial anesthesia and only 8% (34,356) had general anesthesia. Severe PPD requiring hospitalization occurred in 1158 women with 60% identified during readmission. General anesthesia was found to be associated with a 54% increased odds of PPD, and a 91% increased odds of suicidal ideation or self-inflicted injury. There was insufficient evidence for increased risk of anxiety orders.

Latency of preterm hypertensive disorders of pregnancy and subsequent cardiovascular complications.
The objective of this retrospective cohort study was to test the hypothesis that increasing latency from diagnosis to delivery in patients with preterm hypertensive disorders of pregnancy is associated with an increased maternal risk of cardiovascular admission after delivery. The investigators found that prolonging expectant management of preterm hypertensive disorders of pregnancy was associated with an increased risk of maternal cardiovascular disease after delivery.

Development and validation of a risk prediction model for cesarean delivery after labor induction.
The goal of this study was to develop and validate a prediction model for cesarean delivery after labor induction that included factors known before the start of induction. The model contained eight variables, was well calibrated with good risk stratification at the extremes of predicted probability, and performed well on internal validation. The authors concluded that their prediction model can help providers estimate a woman's risk of cesarean delivery when planning a labor induction.

Elucidating the role of overweight and obesity in racial and ethnic disparities in cesarean delivery risk.
This study’s goal was to quantify the extent to which overweight and obesity explain cesarean delivery rates among women of different racial and ethnic backgrounds. Administrative records were used from New York City for 216,481 singleton, nulliparous births from 2008 to 2013. Risk ratios, risk differences, and population attributable fractions for associations between body mass index and cesarean, stratified by race and ethnicity was calculated. Black and Hispanic women had the highest cesarean rates attributable to obesity and overweight (17.4% and 14.6%) respectively.

Expectant management of hypertensive disorders of pregnancy and future cardiovascular morbidity.
The purpose of this study was to test the hypothesis that a longer length of time between diagnosis of hypertensive disorders of pregnancy and delivery is associated with increased risk of cardiovascular morbidity in the years after delivery. The investigators concluded that prolonged expectant management of preterm hypertensive disorders of pregnancy was associated with an increased risk of maternal cardiac disease in the ensuing years.

Methodology for sampling women at high maternal risk in administrative data.
This study compared the net benefits of using the Obstetric Comorbidity Index (OCI) to identify women at high maternal risk compared to conventional risk identification methods. Hospitalization discharge and vital records data for women experience singleton births in George from 2008 to 2012 was used. Results found there was a small but positive net benefit in using the OCI and conventional risk identification methods actually performed worse than using no risk identification methods at all. The researchers suggest that using OCI helps reduce misclassification.

Association between severe maternal morbidity and psychiatric illness within 1 year of hospital discharge after delivery.
The purpose of this study was to estimate whether severe maternal morbidity is associated with increased risk of psychiatric illness in the year after delivery hospital discharge. Results showed that although absolute numbers were modest, severe maternal morbidity was associated with increased risk of severe postpartum psychiatric morbidity and substance use disorder. The highest period of risk extended to 4 months after hospital discharge.

Are overweight and obesity associated with increased risk of cesarean delivery in Mexico? A cross-sectional study from the National Survey of Health and Nutrition.
Researchers conducted a cross-sectional study to test the association between overweight and obesity and cesarean delivery in Mexico using data from the 2012 National Survey of Health and Nutrition (ENSANUT). They found that multiparous women with obesity are at higher risk of cesarean delivery in Mexico than multiparous women with normal body mass index. They recommend that efforts to reduce the cesarean deliveries rate take the obesity epidemic into account.

Dietary quality and glycemic control among women with gestational diabetes mellitus.
Poor dietary quality, measured by the Healthy Eating Index 2010 (HEI-2010), is associated with risk of gestational diabetes mellitus (GDM) and type 2 diabetes. The aim was to investigate the association between dietary quality and glycemic control in women with GDM. The authors concluded that clinicians should be aware that even a small improvement in diet quality may be beneficial for the achievement of improved glycemic control in women with GDM.
