BackgroundReadmission rates are used as a quality metric in medical and surgical specialties; however, little is known about obstetrics readmissions.ObjectiveOur goals for this study were to describe the trends in postpartum readmissions over time; to characterize the common indications and associated diagnoses for readmissions; and to determine maternal, delivery, and hospital characteristics that may be associated with readmission.Study DesignPostpartum readmissions occurring within the first 6 weeks after delivery in California, Florida, and New York were identified between 2004 and 2011 in State Inpatient Databases. Of the 5,949,739 eligible deliveries identified, 114,748 women were readmitted over the 8-year period. We calculated the rates of readmissions and their indications by state and over time. The characteristics of the readmission stay, including day readmitted, length of readmission, and charge for readmission, were compared among the diagnoses. Odds ratios were calculated using a multivariate logistic regression to determine the predictors of readmission.ResultsThe readmission rate increased from 1.72% in 2004 to 2.16% in 2011. Readmitted patients were more likely to be publicly insured (54.3% vs 42.0%, P < .001), to be black (18.7% vs 13.5%, P < .001), to have comorbidities such as hypertension (15.3% vs 2.4%, P < 0.001) and diabetes (13.1% vs 6.8%, P < .001), and to have had a cesarean delivery (37.2% vs 32.9%, P < .001). The most common indications for readmission were infection (15.5%), hypertension (9.3%), and psychiatric illness (7.7%). Patients were readmitted, on average, 7 days after discharge, but readmission day varied by diagnosis: day 3 for hypertension, day 5 for infection, and day 9 for psychiatric disease. Maternal comorbidities were the strongest predictors of postpartum readmissions: psychiatric disease, substance use, seizure disorder, hypertension, and tobacco use.ConclusionPostpartum readmission rates have risen over the last 8 years. Understanding the risk factors, etiologies, and cause-specific timing for postpartum readmissions may aid in the development of new quality metrics in obstetrics and targeted strategies to curb the rising rate of postpartum readmissions in the United States.Copyright © 2016 Elsevier Inc.
