Medical indications for primary cesarean delivery in women with and without disabilities.
The purpose of this study was to examine the associations between maternal disability status and type, mode of delivery, and medical indications for cesarean delivery in California deliveries. Findings showed that women with disabilities were less likely to labor, and these unlabored cesarean deliveries were less likely to have a medical indication for cesarean, compared to women without disabilities.

Missed nursing care during labor and birth and exclusive breast milk feeding during hospitalization for childbirth.
The purpose of this study was to determine associations between missed nursing care and nurse staffing during labor and birth, and exclusive breast milk feeding at hospital discharge. Exclusive breast milk feeding is a national quality indicator of inpatient maternity care. Nurses have substantial responsibility for direct support of infant feeding during the childbirth hospitalization. The investigators indicate that the results support exclusive breast milk feeding as a nurse-sensitive quality indicator.

Identifying cardiovascular severe maternal morbidity in epidemiologic studies.
This study’s goal was to identify cases of cardiovascular severe maternal morbidity (CSMM) for use in epidemiologic studies. CSMM has become the leading cause of maternal mortality. The authors analyzed delivery hospitalizations at an obstetric teaching hospital from 2007 to 2017. A subset of indicators developed by the CDC based on ICD codes were utilized to form the composite variable for CSMM. Two expert clinicians manually reviewed all qualifying events using a standardized tool to determine if they were true CSMM events. They also estimated the number of CSMM cases among delivery hospitalizations without qualifying ICD codes by manually reviewing all severe preeclampsia cases and a random sample of 1000 hospitalizations without severe preeclampsia. Among 91,355 delivery admissions, they captured 113 potential CSMM cases. Of those 65 (57.5%) were true CSMM cases. Indicators for acute myocardial infarction, cardiac arrest, and cardioversion had 100% true-positive rates. An additional 70 CSMM cases in the 2102 admissions with severe preeclampsia were found.

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.

Understanding the heterogeneity of labor and delivery units: using design thinking methodology to assess environmental factors that contribute to safety in childbirth.
There is limited research exploring the relationship between design and patient safety outcomes, especially in maternal and neonatal care. In this study, the investigators employed design thinking methodology to understand how the design of labor and delivery units impacted safety and identified spaces and systems where improvements are needed.

Prevalence of malignant hyperthermia diagnosis in obstetric patients in the United States, 2003 to 2014.
The goal of this study was to assess the prevalence of malignant hyperthermia (MH) diagnosis and associated factors in obstetric patients. Using data from the Nationwide Inpatient Sample, results showed that the prevalence of MH-susceptibility is about 1 in 125,000 in cesarean deliveries, similar to the prevalence reported in non-obstetrical surgery inpatients. The findings of this study suggest that stocking dantrolene in maternity units is justified.

Low-interventional approaches to intrapartum care: hospital variation in practice and associated factors.
This study compared hospitals in California with low and high-interventional practices for labor and delivery. A total of 185 California hospitals completed a survey of intrapartum care, including questions on low- versus high-interventional practices. They identified 2 distinct groups of hospitals that tended to use low- or high-interventional practices. Hospitals that used low-interventional practices tended to have midwife-led or physician-midwife collaborative labor management or were in rural locations. High-interventional practice hospitals had a higher proportion of women covered by Medicaid or other safety-net programs as well as hospitals located in counties with higher liability insurance premiums. Both sets of hospitals had comparable morbidity rates but low-intervention hospitals had lower rates of cesarean birth and episiotomies. Only one-quarter of hospitals were found to use low-interventional practices.

Preventing cesarean birth in women with obesity: influence of unit-level midwifery presence on use of cesarean among women in the Consortium on Safe Labor data set.
The primary goal of this study was to examine associations between midwifery unit-level presence and unplanned cesarean birth in women with different body mass index (BMI) ranges. Data from the Consortium on Safe Labor was used to analyze information on low-risk, healthy women who labored and gave birth in medical centers with or without the unit-level presence of midwives. Results indicate that the odds of unplanned cesarean birth among women who gave birth in centers with midwives were 16% lower than the odds of cesarean birth among similar women who gave birth at centers without midwives. However, women whose BMI was above 35.00 kg/m at labor admission had similar odds of cesarean birth, regardless of unit-level midwifery presence. Although integration of midwives into the caregiving environment of medical centers in the United States was associated with overall decrease in the incidence of cesarean birth, increased maternal BMI nevertheless remained positively associated with these outcomes.
