Patient Activity Scale II (PAS II) for RA

Quantifies severity of rheumatoid arthritis (RA) and has fewer questions than PAS.

Note: The PAS II is an alternative to the PAS. PAS II uses a slightly different questionnaire with fewer questions than the original PAS, though the overall accuracy of the two is the same.

Advice
  • Interpret results alongside clinical findings and laboratory data to guide treatment decisions.
  • Use the score to support shared decision-making and discussions around treatment goals and symptom burden.
  • If moderate or high activity is indicated, reassess the current RA treatment regimen and consider escalation of therapy.
  • Evaluate for comorbid, noninflammatory conditions if scores remain persistently elevated.
  • Repeat the score regularly to track treatment effectiveness and disease control.
