949-P: Reasons for Nonelective Readmissions among Hospitalizations with Diabetes Complicating Pregnancy and the Perinatal Period: Insights from the U.S. National Readmission Database for 2018

Introduction: With the increasing prevalence of diabetes mellitus (DM), there is an increasing burden of DM among pregnant women. Gestational DM (GDM), is a known complication of pregnancy which could affect the outcome for mother and child. This study looked into the burden of DM related gestations and readmissions. Methods: Data was obtained from the US National Readmissions Database for 2018, the largest database for readmissions in the US, which approximates yearly estimates. Index hospitalizations for DM complicating pregnancy and the postpartum period were obtained using ICD-10 codes. Hospitalizations less than 18 years of age and elective admissions were excluded. Outcomes included the rate of 30-day readmission (30DR) as well as identifying the commonest reasons for readmission among the studied cohort. Results: A total of 61,675 hospitalizations were included in the study as index admissions. Of these hospitalizations, 2,768 (4.50%) were readmitted within 30 days of discharge. The top reasons for readmission included severe pre-eclampsia, gestational DM, pre-existing DM type 1 in pregnancy, maternal care for scar from previous cesarean delivery, pre-existing DM type 2 in pregnancy and endometritis following delivery. Readmission was associated with increased healthcare utilization. Conclusion: Among pregnancies complicated by DM that led to hospitalization, a small proportion of patients get readmitted within 30 days for known complications of pregnancy. These could be associated with mortality, hence, research into factors and predictors of readmission in this population should be encouraged. Disclosure M. C. Aguilera: None. H. Shaka: None. C. D.
