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.
