Using Computerized Physician Order Entry to Ensure Appropriate Vaccination of Patients with Inflammatory Bowel Disease.

Background: Inflammatory bowel disease (IBD) is a disorder in which an aberrant immune response in a genetically susceptible host, with influences from environmental factors, leads to intestinal inflammation. Vaccines against influenza and pneumococcal pneumonia are indicated for all patients with IBD, while vaccines such as hepatitis A and B, human papillomavirus, and meningococcal meningitis are only indicated for patients with specific risk factor profiles. Some vaccines are contraindicated for patients receiving immunosuppressive medications; typically, these are live or live attenuated vaccines such as measles-mumps-rubella, varicella zoster, and herpes zoster.
