Harvey-Bradshaw Index - Measuring Crohn’s Disease


The Harvey-Bradshaw Index (HBI) is a useful tool for assessing the degree of illness (activity) in patient's with Crohn's disease.  The index is less cumbersome to use than the CDAI and eliminates the use of the diary card (patient pre-assessment) and laboratory monitoring. The HBI has been found to be quite useful in the management of this disease including periodic assessments of response rates to individual treatments  and the assessment of the long term progress.1

Correlating this simple index to the CDAI has shown that the HBI is more than adequate at generating an index that closely approximates disease severity based on a relatively short list of clinical criteria.  Further, there appears to be no need to average symptoms out over a period of seven days or to use weighting factors.1
General well-being: subjectively assessed -  0 (generally well), 1= slightly under par,  2=poor,  3=very poor, 4 =terrible




Abdominal pain (graded from 0-3 on severity)  (for the previous day).    0=none,  1=mild,  2=moderate, 3=severe




Number of liquid or soft stools - previous day:




Abdominal mass - (0 = none, 1 = dubious, 2 = definite, 3 = definite and tender)




Complications (score 1 per item):
(Check all that apply)

  Joint pain (arthralgia)

  Inflammation of the middle layer of the eye (uveitis)

  Erythema nodosum

  Aphthous ulcers

  Pyoderma gangrenosum

  Anal fissure

  New fistula

  Abscess
