Risk Factors & Timing in Postpartum Stroke

Obstet Gynecol; ePub 2017 Dec 4; Too, Wen, et al

The majority of readmissions for postpartum stroke occur within 10 days of discharge, with patients with chronic hypertension and hypertensive diseases of pregnancy at higher risk, a recent study found. The retrospective cohort study used the Healthcare Cost and Utilization Project’s Nationwide Readmissions Database for 2013 and 2014 to evaluate risk of readmission for stroke within 60 days of discharge from a delivery hospitalization. Researchers found:

  • 6,272,136 delivery hospitalizations were included in the analysis.
  • 1,505 cases of readmission for postpartum stroke were identified.
  • 214 (14.2%) cases of stroke occurred among patients with hypertensive diseases of pregnancy, 66 (4.4%) with chronic hypertension, and 1,225 (81.4%) without hypertension.
  • The majority of stroke readmissions occurred within 10 days of hospital discharge (58.4%), including 53.2% of patients with hypertensive diseases of pregnancy during the index hospitalization, 66.7% with chronic hypertension, and 59% with no hypertension.
  • Hypertensive diseases of pregnancy and chronic hypertension were associated with increased risk of stroke readmission vs no hypertension (OR, 1.74).
