The Patient Activity Scale (PAS) questionnaire contains a combination of single measures from the Health Assessment Questionnaire (HAQ) as well as the patient's assessment of pain in the past week and global assessment of pain (PtGA). The combined scores from these measures are used to derive the PAS total score [LOINC: 75840-9]. The PAS is calculated by multiplying the HAQ by 3.33 and then dividing the sum of the pain scale, PtGA and HAQ by 3. Assessment of disease activity for PAS may be defined as remission ≤0.25, minimal ≤3.7, moderate <8.0 and severe ≥8.0. The PAS and PAS-II [LOINC: 75875-5] contain only patient derived data and are useful for the overall, continuous measure of rheumatoid arthritis (RA) disease activity.
