CDAI v.1

Clinical disease activity index (CDAI) is a composite score for assessing disease activity in individuals with rheumatoid arthritis (RA). It is the numerical sum of four parameters: the number of tender (0 - 28) and swollen (0 - 28) joints the patient has, and the visual analogue scale scores for patient (0 - 10) and physician (0 - 10) global assessments of the level of disease activity [0.0 = low disease activity/patient doing very well; 10.0 = high disease activity/patient doing very poor].

This guideline calculates the clinical disesase activity index (CDAI) which is a measure of disease activity and treatment response in individuals with rheumatoid arthritis.

Use to calculate CDAI, based on four input parameters: tender joint count (TJC), swollen joint count (SJC), patient global assessment of disease activity (PtGDA), and provider global assessment of disease activity (PrGDA). PtGDA and PrGDA use the unit 'cm'. CDAI = TJC + SJC + PtGDA + PrGDA

Do not use to calculate simplified disease activity index (SDAI).
