Score points

The Harvey-Bradshaw index was devised in 1980 as a simpler version of the Crohn's disease activity index (CDAI) for data collection purposes. It consists of only clinical parameters: The first three items are scored for the previous day. Harvey-Bradshaw index is far simpler to use than the CDAI and does not require biochemical tests.

Patients with Crohn's disease who scored 3 or less on the HBI are very likely to be in remission according to the CDAI. Patients with a score of 8 to 9 or higher are considered to have severe disease.
