How this service works
Wolfe 2005 Patient Activity Scale (PAS): (haq * 3.33 + pain_vas + patient_global_vas) / 3. HAQ 0-3 (not HAQ-II); pain and patient global 0-10 VAS. magent does not administer the HAQ. Not PAS-II, Samuel 2002 pediatric appendicitis PAS, DAS28, or CDAI. Not a diagnosis. PAS total only; no remission or severity cutoffs.
Output
Returns the computed PAS total score as a single numeric value, calculated as (HAQ × 3.33 + pain VAS + patient global VAS) / 3. No severity cutoffs, remission thresholds, or sub-scores are provided — just the raw composite total.
Example use cases
RA clinic visit disease tracking
“My RA patient today has a HAQ disability index of 0.875, pain VAS of 4.0, and patient global VAS of 3.5 — what is their PAS score?”
Longitudinal RA outcome monitoring
“We tracked a patient over three visits. At this visit their HAQ is 2.0, pain VAS is 7.5, and patient global VAS is 8.0. Compute their Patient Activity Scale score so I can compare it to last month.”
Research data pipeline PAS calculation
“For my RA registry dataset, calculate the PAS for a subject with HAQ=0.25, pain_vas=1.5, and patient_global_vas=2.0 using the Wolfe 2005 formula.”

Endpoint
GEThttps://api.magentlab.com/api/calc/pas_raWhen to prefer
Use this endpoint when you need a fast, deterministic, arithmetic-only computation of the Wolfe 2005 PAS for rheumatoid arthritis and already have caller-supplied HAQ (0-3 scale, not HAQ-II), pain VAS (0-10), and patient global VAS (0-10) values. Do not use if you need PAS-II, pediatric appendicitis PAS (Samuel 2002), DAS28, CDAI, HAQ administration, severity categorization, or remission cutoffs.
Side effects
- HAQ value out of 0-3 range returns validation error
- pain_vas or patient_global_vas out of 0-10 range returns validation error
- Missing required parameters returns 400-level error
- Payment not provided or insufficient balance returns 402 Payment Required
