SCCAI Calculator

A score for ulcerative colitis made entirely from symptoms you report: bowel movements, urgency, bleeding, wellbeing and problems outside the gut.

The Simple Clinical Colitis Activity Index (SCCAI) describes how active ulcerative colitis is, using only what you report: bowel movements during the day and at night, urgency, blood in your stools, how you feel, and problems outside the gut such as joint pain. It was published in 1998 and scores from 0 to 20.

It needs no blood test, colonoscopy or examination, so you can fill it in yourself before an appointment. Studies usually count a score of 2 or under as remission.

How the SCCAI score is used where you live

Australia

Your IBD team may use the SCCAI to track how active ulcerative colitis is. For subsidised medicines, Australia’s PBS (its medicines subsidy scheme) asks for a Mayo or partial Mayo score instead. See the partial Mayo calculator.

Canada

In Canada, provincial drug plans and private insurers set their own rules for some ulcerative colitis medicines, and some of them ask your specialist for a disease activity score. Your IBD team may use the SCCAI to track how active ulcerative colitis is. In British Columbia, for example, PharmaCare’s Special Authority form for these medicines asks for a partial Mayo score instead. See the partial Mayo calculator.

New Zealand

In New Zealand, Pharmac, the government agency that decides which medicines are funded, asks for a Special Authority form for some of them. One of Pharmac’s Special Authority forms, for example, uses an SCCAI of 4 or more to start treatment, and a fall of 2 points or more to continue it. Source: Pharmac: Special Authority form SA2183.

United Kingdom

Your IBD team may use the SCCAI to track how active ulcerative colitis is. Medicines funding rules that ask for a score say which one they need.

United States

In the US, health insurers set their own rules for approving some ulcerative colitis medicines, and some ask your doctor for a disease activity score. Your IBD team may use the SCCAI to track how active ulcerative colitis is.

Somewhere else

Your IBD team may use the SCCAI to track how active ulcerative colitis is. Medicines funding rules that ask for a score say which one they need.

What the total means

The SCCAI score describes how active ulcerative colitis looks from the answers given. If your IBD team asks you to answer for a set number of days, use those days. It doesn’t diagnose anything, and your IBD team reads it alongside everything else they know about you.

  • 2 or under: the range studies commonly use for remission
  • 3 or more: the range studies count as active ulcerative colitis
