The Disease Activity Score (DAS) is a system of measurement developed in the 1980s that uses certain criteria, including joint counts and patient perceived disease activity, to measure disease activity in people with Rheumatoid Arthritis . More recently, the European League against Rheumatism (EULAR) has developed a new system of measurement known as the Rheumatoid Arthritis Impact of Disease score, or EULAR-RAID score. The EULAR-RAID score is a composite score based on patient reported outcomes, and includes such criteria as pain, functional disability, fatigue, sleep disturbances, coping, overall assessment of physical well being and overall assessment of psychological well being. The objective of this study is to evaluate the practical modalities and performance of the EULAR- RAID score in patients with rheumatoid arthritis who have been prescribed etanercept as part of usual medical practice.

Reliability of the European League Against Rheumatism - Rheumatism Arthritis Impact of Disease (EULAR-RAID) Score
EULAR-RAID score reliability assessed using an intraclass correlation coefficient (using a consistency definition where the between-measure variance is excluded from the denominator variance and its 95% confidence interval) and the standard error of measurement (SEM) and its 95% confidence interval (CI). A higher intraclass correlation coefficient (ICC) indicates greater score reliability (0.0 to 0.10=virtually none; 0.11 to 0.40=slight; 0.41 to 0.60=fair; 0.61 to 0.80=moderate; 0.81 to 1.00=substantial).
Time frame: Screening, baseline
Simplicity: Time for Completion of the EULAR-RAID Questionnaire
EULAR-RAID is an assessment of patient reported outcomes for pain, functional disability, fatigue, sleep disturbance, coping, overall assessments of physical well-being and emotional well-being based on 7 numerical rating scales (NRS) questions. NRS individual questions with range of 0 (not affected, very good) to 10 (most affected) weighted and calculated with a total score range of 0 (not affected, very good) to 10 (most affected).
Time frame: Baseline up to Week 12
Face Validity: Correlation Coefficients of the EULAR-RAID Score With the Disease Activity Score Based on 28-joints Count (DAS28)
DAS28 calculated from the number of swollen joints (SJC) and painful joints (PJC) using the 28 joints count, the erythrocyte sedimentation rate (ESR) (millimeters per hour \[mm/hour\]) and patient's global assessment (PGA) of disease activity (participant rated arthritis activity question measured on an 11-point rating scale scored 0 \[none\] to 10 \[extreme\]). Face validity assessed using a correlation coefficient between the EULAR-RAID score and the DAS28. A higher correlation coefficient indicates greater EULAR-RAID score validity.
Time frame: Baseline, Week 4

Time-normalized average is the area under the curve (AUC) / time between first and last observations. DAS28 calculated from number of swollen joints and painful joints using 28 joints count, ESR (mm/hour) and patient's global assessment of disease activity (participant rated arthritis activity question measured on an 11-point rating scale scored 0 \[none\] to 10 \[extreme\]).

Sensitivity to Change of the EULAR-RAID Score: Change From Baseline to Week 4
Sensitivity to change analyzed by testing if the difference of change from baseline of EULAR-RAID score minus the change from baseline of each component (pain, functional disability, fatigue, sleep disturbance, coping, overall physical and emotional well-being with score range 0 \[not affected, very good\] to 10 \[most affected\]) was different from 0 or not. Results expressed as standardized response mean (SRM) calculated as ratio of mean change over standard deviation of the change. A non significant test (p value ≥0.05) means the component had a significant influence to global EULAR RAID score.
