Background:Patients with Inflammatory Bowel Disease (IBD) are at heightened risk of infection, and are often under vaccinated. At our institution, IBD patients may follow up with one of three gastroenterology (GI) providers: IBD specialists, GI Fellows and General GI providers. Aims: Our primary objective was to identify whether the type of GI provider had an effect on rates of vaccinations for IBD patients. The seven vaccines studied were listed in the American College of Gastroenterologyâs 2017 Guidelines on Preventative Care in IBD, and include Influenza, Tetanus/Diphtheria/Pertussis, Hepatitis A (HAV), Hepatitis B (HBV), Pneumococcus (PCV13 and PPSV23), Meningococcus, and Human Papillomavirus (HPV).Methods:Retrospective case control study of IBD patients, looking at vaccination rates for each of the seven vaccinations listed above, and type of GI provider followed. Other data collected included patient demographics, IBD type, treatment regimen and insurance.Results:Of 338 IBD patients, 65 (19.2%) followed up with a GI fellow, 110 (32.5%) with a general GI provider, and 163 (48.2%) with an IBD specialist. HBV was the only vaccine with a significant difference in vaccination rate by type of provider. Bivariate analysis showed that patients who followed with IBD specialists and GI fellows were more likely to be vaccinated for HBV than patients who followed up with general GI provider (OR = 2.55, p = .003 and OR = 2.73, p = .007 respectively).Conclusion Type of GI provider only impacted rates of vaccination for HBV among IBD patients in this study, with IBD specialists and GI fellows outperforming general GI providers.
