Differential impact of migraine on severe maternal morbidity and postpartum readmissions: Insights from a national cohort study

Key Points

To investigate the impact of migraine on severe maternal morbidity and postpartum readmission rates.
Analyzed data from a national cohort of pregnant women
Assessed obstetric comorbidity scores related to migraine
Evaluated 30-day non-elective readmission rates and costs
Women with migraine exhibited higher obstetric comorbidity scores
Migraine was linked to increased rates of 30-day readmissions
Higher hospitalization costs were associated with migraine cases

Abstract

Women with migraine have higher obstetric comorbidity scores, which may contribute to the elevated risk of SMM. Migraine itself is independently associated with increased 30-day nonelective readmission rates and hospitalization costs. These associations, along with the large number of unspecified migraine diagnoses, highlight the importance of thorough migraine screening and documentation, which may help guide interventions to improve maternal outcomes and reduce healthcare burden.
