CASPAR Criteria for Psoriatic Arthritis
Provides classification criteria for psoriatic arthritis.
Advice
- These criteria are not a standalone diagnostic tool but can assist clinicians in evaluating and identifying potential PsA cases; their application should always be guided by clinical context and judgment.
- A potential PsA diagnosis should prompt:
- Referral to a rheumatologist, if not already involved.
- Initiation or adjustment of treatment to target inflammation and prevent disease progression (e.g., NSAIDs, DMARDs, biologics).
- Comprehensive assessment for comorbidities like uveitis, inflammatory bowel disease, and cardiovascular risk factors, which are common in PsA.
- Regular monitoring of disease activity and adjustment to management plans, as necessary.
- For patients who do not meet the criteria, consider alternative diagnoses such as rheumatoid arthritis, reactive arthritis, other spondyloarthropathies, osteoarthritis, or crystal arthropathies, and pursue additional workup based on the clinical presentation.
- Please refer to relevant PsA clinical guidelines, such as those from the American College of Rheumatology, for more detailed recommendations.
