Psoriatic Arthritis Response Criteria (PsARC)

Description

Clegg et al reported response criteria for patients being treated for psoriatic arthritis. These can help to monitor a patient over time and to gauge the effectiveness of an intervention. The authors are from multiple Veterans Administration medical centers in the United States.

Measures:

(1) patient assessment on a scale from 1 to 5 (lower better)

(2) physician assessment on a scale from 1 to 5 (lower better)

(3) percent change in joint pain and/or tenderness

(4) percent change in joint swelling

Measure	Better	No Change	Worse
patient self- assessment	decrease 1 point	no change	increase 1 point
physician assessment	decrease 1 point	no change	increase 1 point
joint pain and/or tenderness	decrease 30% or more	decrease 29% to increase 29%	increase 30% or more
joint swelling	decrease 30% or more	decrease 29% to increase 29%	increase 30% or more

Treatment response was defined as:

(1) better in 2 or more measures

(2) better in joint pain and/or tenderness or in joint swelling

(3) none of the measures worse
