Abstract

Background: Kentucky was among the first to adopt Medicaid expansion, resulting in reducing uninsured rates from 14.3% to 6.4%. We hypothesize that Medicaid expansion resulted in increased elective healthcare utilization and reductions in emergency treatments by patients suffering Inflammatory Bowel Disease (IBD).

Methods: The Hospital Inpatient Discharge and Outpatient Services Database (HIDOSD) identified all encounters related to IBD from 2009 to 2020 in Kentucky. Several demographic variables were compared in pre- and post-Medicaid expansion adoption.

Results: Our study analyzed 3386 pre-expansion and 24,255 post-expansion encounters for IBD patients. Results showed that hospitalization rates dropped (47.7%-8.4%), outpatient visits increased (52.3%-91.6%) and Emergency visits decreased (36.7%-11.4%). Admission following a clinical referral similarly increased with a corresponding drop in emergency room admissions. Hospital costs and lengths of stay also dropped following Medicaid expansion.

Conclusion: In the IBD population, Medicaid expansion improved access to preventative care, reduced hospital costs by decreasing emergency care, and increased elective care pathways.
