Abstract
Objective
To examine the influence of socioeconomic, clinical, and hospital characteristics on the risk of severe maternal morbidity among postpartum readmissions.
Study Design
A cross-sectional analysis was conducted using the National Inpatient Sample 2006–2012 to estimate the risk of severe maternal morbidity and identify potential risk factors. Odds ratios were calculated using multivariate logistic regression.
Results
Women aged ≥35 years (ages 35–39: OR 1.12 [CI 1.06, 1.19]; ages 40+: OR 1.27 [CI 1.17, 1.39]), non-Hispanic blacks (OR 1.16 [CI 1.10, 1.22]), and women with pre-existing medical conditions (OR 1.62 [CI 1.56, 1.68]) were at greater risk of severe maternal morbidity during postpartum readmissions. Women hospitalized outside the Northeast region (Midwest: OR 1.20 [CI 1.10, 1.30]; South: OR 1.29 [CI 1.20, 1.38]; West: OR 1.33 [CI 1.22, 1.44]) were also at increased risk.
Conclusion
The risk of severe maternal morbidity is heightened beyond delivery hospitalization for a subset of high-risk women.
