When to use
- Bedside clinical assessment of Crohn's disease activity without needing laboratory tests, as a simplified alternative to the Crohn's Disease Activity Index (CDAI).
Formula
HBI = general well-being(0-4) + abdominal pain(0-3) + liquid stools/day (1 point each) + abdominal mass(0-3) + number of listed complications (1 point each). <5 = remission; 5-7 = mild; 8-16 = moderate; >16 = severe.
Pearls and pitfalls
- Correlates well with the more complex CDAI while being far quicker to obtain.
- Does not include laboratory markers, so should be interpreted alongside CRP/faecal calprotectin and endoscopic findings when available.
