Objective To assess whether epilepsy is associated with increased odds of 30‐day readmission due to psychiatric illness during the postpartum period. Methods The 2014 Nationwide Readmissions Database and the International Classification of Disease, Ninth Revision, Clinical Modification codes were used to identify postpartum women up to 50 years old in the United States, including the subgroup with epilepsy.
