Table 2 Annual Utilization by IBD Drug Class

From: Examining systemic steroid use in older inflammatory bowel disease patients using hurdle models: a cohort study

  Number of utilizers per 1000 IBD patients per yeara
Class of Agent 2006 2007 2008 2009
 Systemic Steroids 303 345 336 317
 Immunomodulators 48 53 50 45

  1. aMid-year population used to calculate utilizers per year
  2. bNonbiologic immunomodulators include azathioprine, mercaptopurine, and methotrexate
  3. cCell size too small and requires suppression
  4. dThese utilization numbers were derived by dividing the number of patients who received a particular drug class during the year by the mid-year study population and multiplying by 1000.
