Prenatal attitudes toward vaginal delivery and actual delivery mode: variation by race/ethnicity and socioeconomic status.
This study examined whether women's prenatal attitudes toward vaginal delivery differed by race/ethnicity or socioeconomic status, and whether attitudes were differently related to delivery mode depending on race/ethnicity or socioeconomic status. The study concluded that there are racial/ethnic differences in chances of cesarean delivery, and these differences are not explained by birth attitudes. Findings also suggested that white and high-socioeconomic status women may be more able to realize their preferences in childbirth.

Competitive effects of scope of practice restrictions: public health or public harm?
This paper examined the case of scope of practice (SOP) restrictions for certified nurse midwives and evaluated the effects of changes in states' SOP laws on markets for CNMs and on maternal and infant outcomes. The authors found that SOP laws are neither helpful nor harmful in regards to health outcomes but states that have no SOP-based barriers have lower rates of induced labor and Cesarean section births.

Tackling quality improvement in the delivery room.
Implementation of standardized practices in the delivery room fosters a safe environment to ensure that newborn infants are cared for optimally. This article discusses how the delivery room is a unique environment and presents examples on how to approach delivery room quality improvement (QI). Key areas of potential focus for teams pursuing delivery QI include thermal regulation, optimizing respiratory support, and facilitating team communication.

Influence of patient-level factors on mode of delivery among operative vaginal delivery candidates in modern practice.
This study aimed to evaluate which patient-level factors influence mode of delivery among candidates for operative vaginal delivery. Odds of forceps versus vacuum were higher with induction, nulliparity, epidural, maternal indication, older maternal age, and longer second stage. Odds of cesarean versus operative vaginal delivery were higher with maternal indication, a perinatologist, longer second stage, older gestational age and longer labor.

Association between off-peak hour birth and neonatal morbidity and mortality among very low birth weight infants.
This study assessed the independent association between overnight or "off-peak" hour delivery and 3 neonatal morbidities strongly associated with childhood neurocognitive impairment. It found that very low birth weight infants born between midnight and 7:00 a.m. are at increased risk for severe intraventricular hemorrhage and death or major neonatal morbidity.

Live birth, miscarriage, and abortion among U.S. women with and without disabilities.
Researchers compared proportions of live birth, miscarriage, and abortion among women with basic action difficulties, women with complex activity limitations, and women without disabilities in a nationally representative sample. They found few differences between women with and without disabilities, and good likelihood of live birth among women with disabilities experiencing pregnancy.

Short interpregnancy intervals: results from the first baby study.
Short interpregnancy interval (SIPI), defined as 18 months or fewer between delivery and subsequent conception, has become an independent marker of maternal and child health. The authors of this study performed a secondary analysis of 18 months of data from The First Baby Study, a prospective cohort of women followed from pregnancy through 3 years after their first birth.

Time trends in births and cesarean deliveries among women with disabilities.
This study assessed time trends in births by any mode and in primary cesarean deliveries among women with physical, sensory, or intellectual/developmental disabilities. Among all women giving birth, the proportion with a disability increased from 0.27 percent in 2000 to 0.80 percent in 2010. Women with disabilities had significantly elevated odds of primary cesarean delivery in each year, but the magnitude of the odds ratio decreased over time.

Concordance between women's self-reported reasons for cesarean delivery and hospital discharge records.
Researchers compared women's self-reported reasons for cesarean with their hospital discharge records and examined correlates of variability in agreement between sources. Ninety-one percent of women reported a reason for their cesarean that was present in the discharge data. Positive predictive value (PPV), the probability that women's self-reported reasons for cesarean varied by reason for cesarean, with high PPV for dystocia, macrosomia, and cephalopelvic disproportion (91.1 percent), and lower PPV for malposition (81.7 percent).

Preconception low-dose aspirin restores diminished pregnancy and live birth rates in women with low grade inflammation: a secondary analysis of a randomized trial.
This study investigated the effect of preconception-initiated low dose aspirin (LDA) on pregnancy rate, pregnancy loss, live birth rate, and inflammation during pregnancy. It concluded that in women attempting conception with elevated high sensitivity C-reactive protein (hsCRP) and prior pregnancy loss, LDA may increase clinical pregnancy and live birth rates to those of women without inflammation and reduce hsCRP elevation during pregnancy.

Primary cesarean delivery patterns among women with physical, sensory, or intellectual disabilities.
This study sought to determine whether physical, sensory, or intellectual and developmental disabilities are independently associated with primary cesarean delivery. It found that women across disability subgroups have higher odds of cesarean delivery, and there is heterogeneity by disability type.

Changing labor and delivery practice: focus on achieving practice and documentation standardization with the goal of improving neonatal outcomes.
The researchers established a multifactorial shoulder dystocia response and management protocol to promote sustainable practice change. In the first year, there was a threefold increase in shoulder dystocia reporting, which continued in years 2 and 3. In the first year, 96 percent of clinicians completed all training elements. Overall teams reached a 99 percent adoption rate of the shoulder dystocia protocol.

Maternal language and adverse birth outcomes in a statewide analysis.
The study goal was to consider the relationship of maternal language to birth outcomes using Hawaii’s hospitalization data. It found that non-English speakers had approximately two times higher risk of having an obstetric trauma during a vaginal birth when other factors, including race/ethnicity, were controlled. Non-English speakers also had higher rates of potentially high-risk deliveries.

The effect of clinical chorioamnionitis on cesarean delivery in the United States.
This study examined the association of clinical chorioamnionitis on cesarean delivery in a national sample of hospital discharges. It found that women with clinical chorioamnionitis were more likely to have cesarean delivery than those without clinical chorioamnionitis. The risk of cesarean delivery varied significantly by hospital location, teaching status, and U.S. region.

Infant outcomes after elective early-term delivery compared with expectant management.
The purpose of the study was to compare the risk of neonatal morbidity and infant mortality between elective early-term deliveries and those expectantly managed and delivered at 39 weeks of gestation or greater. It concluded that the issues surrounding the timing and reasons for delivery initiation are complicated and each pregnancy unique. Furthermore, it cautions against a general avoidance of all elective early-term deliveries.

Examining the link between women's exposure to stressful life events prior to conception and infant and toddler health: the role of birth weight.
The authors suggested a pathway may exist among maternal exposure to stressful life events prior to conception (PSLEs), infant birth weight, and subsequent offspring health. Infant and toddler health outcomes were assessed at 9 and 24 months, including overall health status, special healthcare needs, and severe health conditions. The analysis suggested a chains-of-risk model in which women's exposure to PSLEs increased the risk for giving birth to a very low birth weight infant, adversely affecting infant and toddler health.

Patient volumes and pre- and postdischarge postpartum infection: a retrospective cohort study.
The researchers examined the association between hospital and clinician obstetric volume and postpartum infection risk in the pre- and postdischarge periods. They found that hospital obstetric volume is positively associated with predischarge postpartum infections, whereas clinician volume may be negatively associated with those predischarge infections.
