The Clinical Disease Activity Index (CDAI) for Rheumatoid Arthritis determines severity of rheumatoid arthritis using only clinical data.

The CDAI is a useful clinical composite score for following patients with rheumatoid arthritis. A CDAI reduction of 6.5 represents moderate improvement.

ra的疾病活动度是指诊断明确的ra患者在某一时间点上疾病所处的状态（缓解/低活动/中活动/高活动）。 临床医生通常会根据患者关节肿痛的程度、血沉及C反应蛋白水平、影像学资料、患者关节功能状态等评估患者的疾病活动度。

评估者整体疾病活动度 (EGA) 评估是指评估者依据 0-10 分量表来评估患者的疾病活动度，其中 10 分代表活动度最大。 CDAI 降低 6.5 反映中度改善。 Aletaha D, Nell VP, Stamm T, et al.

We recommend the Clinical Disease Activity Index, Disease Activity Score with 28-joint counts (erythrocyte sedimentation rate or C-reactive protein), Patient Activity Scale (PAS), PAS-II, Routine Assessment of Patient Index Data with 3 measures, and Simplified Disease Activity Index because they are accurate reflections of disease activity; are ...

目的 评价临床疾病活动指数( cdai)、简化疾病活动指数(sdai)同疾病活动指数28( das28),对类风湿关节炎(ra)疾病活动性的评估价值.方法 连续纳入200例ra患者,评估每例ra患者的关节肿胀数(sjc)、关节压痛数(tjc)、患者对病情的总体评估(pga)、医生对病情的总体评估( phga ...

Five preferred RA disease activity measures for regular clinical use were selected: CDAI, DAS28-ESR/CRP, PAS-II, RAPID3, and SDAI. Seven additional RA disease activity measures that met a “minimum standard” for regular use were identified: DAS, patient derived DAS28, HUPI, MBDA score, RADAI, RADAI-5, and RAPID5.

Assess disease activity in rheumatoid arthritis, without requiring lab work. 1.Swollen Joint Count? 2.Tender Joint Count? 3.Patient Global Assessment? 4.Evaluator Global Assessment? Clinical disease activity index (CDAI) is a simplification from the SDAI as it does not require the measurement of an acute phase reactant.

CDAI is a measure used to assess disease activity in rheumatoid arthritis patients based on symptoms and physical examination findings.
