Simplified disease activity index [SDAI]
Active
Term Description
The Simplified (or Simple) Disease Activity Index (SDAI) instrument contains several measurements or scores used to determine rheumatoid arthritis disease activity. The overall SDAI score is calculated using a linear sum of the following: tender 28 joint count, swollen 28 joint count, patient global assessment, physician global assessment, and C-reactive protein levels. The SDAI is similar to the CDAI (Clinical Disease Activity Index, [LOINC: 75842-5]), which uses the same measures as the SDAI except it does not include the measurement of C-reactive protein levels.
