Term Description
The Simplified Disease Activity Index (SDAI) is a useful clinical composite score for measuring a patient's rheumatoid arthritis activity in a clinical setting. It is scored by simply adding the numerical values within each of a set of predetermined areas: a twenty eight joint assessment is used to measure tender and swollen joint count; a patient and physician global assessment of disease activity is measured using a visual analogue scale, and finally, levels of the protein C-reactive are measured (mgudl, normal <1 mgudl).
