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
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
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,
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)
