LOINC long common name : Patient activity scale II [PASII];
LOINC description : The Patient Activity Scale II (PAS-II) questionnaire contains a combination of single
measures from the Health Assessment Questionnaire II (HAQ-II) 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-II total score [LOINC: 75841-7].
The PAS-II is calculated by multiplying the HAQ-II by 3.33 and then dividing the sum
of the pain scale, PtGA and HAQ-II by 3. Assessment of disease activity for PAS-II
may be defined as remission 0.25, minimal 3.7, moderate 8.0 and severe 8.0. The
PAS [LOINC: 75877-1], a longer version, and PAS-II contain only patient derived data
and are useful for the overall, continuous measure of rheumatoid arthritis (RA) disease
activity.;
