Psoriatic arthritis (PsA) is a heterogeneous disease that includes features of peripheral arthritis, spondylitis, dactylitis, enthesitis as well as extra-articular manifestations such as skin and nail disease. As a result, PsA has a significant impact on patient function and quality of life. Assessment of all aspects of disease activity is an integral part of disease management.
Measuring Outcome in PsA (MOPSA) provides patients and clinicians with web-based access to the key instruments required in assessing PsA patients. MOPSA consists of two integrated sections, one to be filled out by patients at or just prior to clinic visit and the other section to be filled out by health care professionals (HCPs) including rheumatologists.
Before you enter any patient data, you will be asked to choose from 2 options: (1) Do you wish to fill out the appropriate data for Minimal Disease Activity (MDA) plus the Composite Psoriatic Disease Activity Index (CPDAI); (2) Do you wish to fill out the appropriate data for MDA only? Once you decide, only the relevant data fields for the chosen option will be shown.
Once the data is entered, MOPSA will automatically calculate the patient’s and HCP's scores including chosen composite score(s). MOPSA will also inform you if your patient meets Minimal Disease Activity (MDA) criteria. Finally, if you have selected CPDAI, MOPSA will show your CPDAI score in the form of a spydergram which will facilitate an easily appreciated summary of all aspects of disease activity and which then can also be compared with previous visit data.
MOPSA can be simply used as a routine clinical tool for assessment of PsA patients or it can also be used in a clinical study setting where specific study sign-up will be required. If you are using this tool for routine clinical use, you should keep a separate list of the patient IDs as we do not use any patient identifiers other than the assigned ID number. It is also possible to download all of your patient-related data (final scores, not the full questionnaires) onto a separate excel spreadsheet.
We hope you will find this tool useful in your clinical practice and we would be happy to receive any comments or suggestions for improvement.
