Minimal Disease Activity (MDA) Scale

The minimal disease activity index is a tool for measuring disease state in psoriatic arthritis.
Technology No. 24032

The minimal disease activity index is a tool for measuring disease state in psoriatic arthritis. It is a composite index comprising seven domains: tender joint count, swollen joint count, psoriasis activity or extent, a functional index (HAQ), enthesitis and two patient completed visual analogue scores, one for pain and one for global disease activity. If 5 of the 7 criteria are met then the patient is deemed to be in minimal disease activity, if all 7 are met the patient is in a very low disease activity state. Almost all new pharmaceuticals tested for psoriatic arthritis are tested against this metric, in addition to others.
