Used in: Inflammatory Bowel Disease

Score interpretation

Remission 0–4

Harvey-Bradshaw Index < 5: Crohn's disease in remission.

→ Continue maintenance therapy (azathioprine, methotrexate, biologic). Review at 3–6 months. Monitoring for side effects and disease activity.

Mildly Active Disease 5–7

Harvey-Bradshaw 5–7: Mildly active Crohn's disease.

→ Review current therapy. Consider corticosteroids (prednisolone 40mg OD tapering). CRP, albumin, faecal calprotectin. Gastroenterology review.

Moderately Active Disease 8–16

Harvey-Bradshaw 8–16: Moderately active Crohn's disease.

→ Admit or urgent outpatient review. IV steroids if not tolerating oral. Imaging (MRI small bowel). Check for infection/abscess. Consider biologic therapy if steroid-dependent or refractory.

Severely Active Disease ≥ 17

Harvey-Bradshaw > 16: Severely active Crohn's disease.

→ Admit. IV hydrocortisone. Exclude infection (stool MC&S, C. diff). Imaging — CT abdomen if complications (perforation, abscess, obstruction). IBD team + surgical review. Nutritional support.
