How this service works
Wolfe 2005 Patient Activity Scale II (PAS-II): (haq_ii * 3.33 + pain_vas + patient_global_vas) / 3. HAQ-II 0-3 (not HAQ); pain and patient global 0-10 VAS. magent does not administer HAQ-II. Not PAS-RA, Samuel 2002 pediatric appendicitis PAS, DAS28, or CDAI. Not a diagnosis. PAS-II total only; no remission or severity cutoffs.
Output
A numeric PAS-II total score derived from the formula (haq_ii * 3.33 + pain_vas + patient_global_vas) / 3. No remission or severity cutoffs are applied — the raw composite value is returned.
Example use cases
RA clinical visit activity tracking
“My rheumatoid arthritis patient today has a HAQ-II score of 0.875, rates their pain as 4 out of 10, and their global health as 5 out of 10 — what is their PAS-II score?”
Longitudinal RA monitoring dashboard
“I'm tracking a patient's disease activity over time. At their last visit HAQ-II was 2.1, pain VAS was 8, and patient global VAS was 7. Can you compute their Wolfe 2005 PAS-II total?”
Research data pipeline scoring
“For our RA registry study, compute the PAS-II for a subject with HAQ-II of 0.25, pain VAS of 2, and patient global VAS of 3.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/pas_iiWhen to prefer
Use this endpoint when you need to compute the specific Wolfe 2005 PAS-II formula for rheumatoid arthritis disease activity monitoring and already have HAQ-II, pain VAS, and patient global VAS values from a clinical assessment. Do not use if you need PAS-RA, pediatric appendicitis PAS (Samuel 2002), DAS28, or CDAI — those are different instruments.
Side effects
- Missing required parameter (haq_ii, pain_vas, or patient_global_vas) returns an error
- HAQ-II value outside 0-3 range may produce out-of-range or rejected output
- pain_vas or patient_global_vas outside 0-10 range may produce invalid results
- Non-numeric inputs cause request failure
- Payment failure (x402) if USDC balance is insufficient
