Patients with high-risk pregnancies and complicated deliveries have an increased risk of maternal postpartum readmissions

Abstract

Objective: Postpartum readmission after initial hospitalization for delivery can be diminished if better understood. The aim of this study was to determine the risk factors and indications for maternal re-hospitalization after delivery, in order to identify preventable factors.

Study design: This was a case control study based on retrospective cohort of patients who delivered at our institution. The patients that were readmitted within 2 weeks of their delivery were included in the study group while the control group was conducted from patients who delivered at the same time but were not re-hospitalized and included twice the number of patients. Demographic characteristics as well as pregnancy, labour and postpartum courses were compared between the two groups.

Results: A total of 227 women were re-hospitalized within 14 days after initial discharge. The control group consisted of 450 women. The demographic characteristics were similar among the two groups, so were the rates of obesity, gestational weight gain and smoking. The major indication for readmission was postpartum infections, most of which were not related to immediate postpartum febrile morbidity. Emergency cesarean section was found to be an independent risk factor for readmission.

Conclusions: The rate of patients with high-risk pregnancies and complicated deliveries is higher among postpartum maternal readmissions. These data might suggest more cautious postpartum care for those patients.
