Social determinants of health (SDOH) are increasingly recognized for their role in perpetuating an inequitable healthcare system, particularly for those with chronic disease. Patients with inflammatory bowel disease (IBD) are likely subject to many of the same inequities, but data on SDOH and IBD outcomes are lacking. The social vulnerability index (SVI) is a publicly available tool from the Centers for Disease Control that provides neighborhood-level estimates of social need with higher values on a 0-1 scale indicating greater social vulnerability.
