Pregnancy Hospitalizations and Substance Use Disorder

"From 2016 to 2020, a total of 3,407,166 inpatient pregnancy hospitalizations were identified from the NIS [Healthcare Cost and Utilization Project National Inpatient Sample] database, of which 3,238,558 (95 %) contained complete information (Appendix B). Of these admissions, 194,930 (6.0 %) were complicated by SUD. Compared with their counterparts, pregnancy hospitalizations among women with SUD were more likely to involve individuals of White ethnicity, between the ages of 20 and 30 years, more often receiving governmental insurance, and within the lowest income quartile (Table 1). Upon evaluation of hospital level characteristics, inpatient admissions among pregnant women with SUD were noted more often among hospitalizations from the Midwestern states, in large hospitals (based on bed size), and in rural hospitals. Distribution of pregnancy hospitalizations was balanced overall over the 5 years, being evaluated with a small annual increase in number of hospitalizations with SUD from 2016 to 2019 (Table 1)."
