Some authors use a modification of the Harvey-Bradshaw index (see above). This modification uses a score for the number of liquid stools per day rather than the raw count.
(1) general well-being
(2) abdominal pain
(3) number of liquid stools per day
(4) abdominal mass
(5) complications (arthralgias, uveitis, erythema nodosum, aphthous ulcers, pyoderma gangrenosum, anal fissure, new fistula, abscess)
For outpatients the first 3 items are scored based on the status of the patient on the day prior to the examination, in order to minimize any effect introduced by coming to the clinic visit.
