Social factors such as race, education, and financial hardships have been shown to affect health outcomes of patients with inflammatory bowel disease (IBD). Although early identification of socially vulnerable patients is critical for targeted interventions, it is still limited by screening tools that are incomprehensive and time-consuming. We investigate the utility of the social vulnerability index (SVI), a census tract-specific measure estimated by the Centers for Disease Control and Prevention, for predicting patients’ healthcare utilization, based on 15 different social determinant variables including employment, housing, and transportation.
