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.

Population-level factors associated with maternal mortality in the United States, 1997-2012.
This study analyzed state-level maternal mortality for the years 1997-2012 using multilevel mixed-effects regression grouped by state, using publicly available data. The study concluded that, in addition to better case ascertainment of maternal deaths, adverse changes in chronic diseases, insufficient healthcare access, and social determinants of health represent identifiable risks for maternal mortality that merit prompt attention in population-directed interventions and health policies.

Hospital variation in cost of childbirth and contributing factors: a cross-sectional study.
The purpose of this study was to examine hospital variation in cost of childbirth hospitalizations and identify factors that contribute to the variation. The study concluded that cost of childbirth hospitalizations varied widely among hospitals in California. Institutional characteristics significantly contributed to this variation. Higher-cost hospitals did not have better outcomes, suggesting potential opportunities to enhance value in care.

Inverse-probability-weighted estimation for monotone and nonmonotone missing data.
The goal of this study was to examine the issue of missing data in epidemiologic research by estimating the association of maternal smoking behavior with spontaneous abortion. Three data sets with induced missing values from the Collaborative Perinatal Project are provided in the article as examples of prototypical epidemiologic studies with missing data. The article also describes a proposed approach to modeling nonmonotone missing-data mechanisms under missingness at random that can be used in constructing the weights in inverse probability weighting complete-case estimation.

Differentiating research, quality improvement, and case studies to ethically incorporate pregnant women.
This article discusses the need to involve pregnant women in research, quality improvement, and case studies and how to involve them in an ethical way with high standards to protect participants. This review includes vignettes to distinguish between the different types of studies and emphasizes that perinatal care providers will need to seek institutional review board approval for all research to be conducted.

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.

The economic value of increasing geospatial access to tetanus toxoid immunization in Mozambique.
The researchers assessed how well tetanus toxoid (TT) immunization locations meet population demand in Mozambique. They found that TT immunization locations are not geographically accessible by a significant proportion of pregnant women, resulting in substantial healthcare and productivity costs that could potentially be averted by adding or reconfiguring TT immunization locations.
