Materials and Methods
The National (Nationwide) Inpatient Sample (NIS) from the Healthcare Cost and Utilization Project for the years 2012–2014 was used for this repeated cross-sectional analysis. The NIS is a large, publicly available, all-payer inpatient contains a sample of approximately 20% of all hospitalizations in the United States. These hospitalizations are selected via a stratified systemic random sample to generate a population representative of the entire United States across medical specialties that
Results
From 2012 to 2014, an estimated 11.3 million births and 207,730 (1.8%) postpartum readmissions were ascertained from the NIS and included in the analysis. The proportion of non-Hispanic black women readmitted relative to delivery hospitalizations was significantly larger (3.09%; 95% CI, 3.06%–3.12%; n=47,015/1,523,190) than other groups, including non-Hispanic white women (1.71%; 95% 1.70%–1.72%; 96,670/5,650,075), Hispanic women (1.52%; 95% CI, 1.50%–1.54%; 33,410/2,194,500), Asian or Pacific
Main findings
In this analysis of postpartum readmissions, non-Hispanic black women were at significantly greater risk (1) to be readmitted postpartum, (2) to suffer severe maternal morbidity during readmission, and (3) to suffer a range of life-threatening complications. Although non-Hispanic black women were at lower risk for complications such as sepsis, shock, hysterectomy, and transfusion, they were particularly likely to receive a diagnosis of pulmonary edema/acute heart failure, with risk more than
