Simple Clinical Colitis Activity Index

The Simple Clinical Colitis Activity Index (SCCAI) is a practical, bedside tool for assessing disease activity in ulcerative colitis and colonic Crohn's disease. Published in 1998 by Walmsley and colleagues, the SCCAI condenses disease assessment into six items that can be administered in a office visit without laboratory or endoscopic data. It provides rapid, reproducible quantification of disease severity and is ideal for frequent monitoring in routine clinical practice.
