Psoriasis arthritis assessment
made easy and quick
What is the eDAPSA?
The Disease Activity index in PSoriatic Arthritis (DAPSA) is used to assess disease activity in patients with confirmed psoriatic arthritis (PsA). The score has become established, particularly in Europe, and is recommended by international experts as a measurement tool for assessing disease activity in PsA. The DAPSA index includes laboratory parameters, clinical aspects, and patient self-assessments.

How to use the eDAPSA
The DAPSA is based on four pillars:
number of joints with pressure pain (0 - 68)
number of swollen joints (0 - 66)
C-reactive protein (CRP) (mg/l)
patient assessment of disease activity and pain.
To calculate the DAPSA or cDAPSA index, the values given above are added together in a sum score.
For the DAPSA:
Pressure painful joints (0 - 68) + swollen joints (0 - 66) + C-reactive protein (mg/l) + disease activity + pain.
To determine disease activity, the following values apply:
0 - 4 remission
5 - 14 low disease activity
15 - 28 medium disease activity
>28 high disease activity
For the cDAPSA:
Pressure painful joints (0 - 68) + swollen joints (0 - 66) + disease activity + pain.
To determine disease activity, the following values apply:
0 - 4 remission
5 - 13 low disease activity
14 - 27 medium disease activity
>27 high disease activity
The following versions of the eDAPSA are available
How was the eDAPSA developed?
The DAPSA was developed by Professor Dr. Smolen and colleagues at the University Hospital in Vienna with the participation of international experts and validated based on clinical data.
To make the DAPSA applicable in clinical practice, a clinical version (cDAPSA) has been developed which can be used independently of inflammatory markers. In validation studies, a high agreement of the cDAPSA and DAPSA could be demonstrated.
