Early diagnosis of psoriatic arthritis (PsA) leads to better long-term health. Patients who wait even as little as six months before getting diagnosed and starting treatment may have worse clinical outcomes.
As a health care provider, it’s up to you to ensure your patients get the care they need as quickly as possible. In the absence of a diagnostic test for PsA, the best thing to do is screen and refer to a specialist.
The Psoriasis Epidemiology Screening Tool, or PEST, is a validated screening tool that can help you recognize signs of PsA in your psoriasis patients*. Patients answer five questions and fill out a diagram. If patients check “yes” to three or more of the questions, they may have PsA. You should speak with them about their symptoms, their options and possibly refer them to a rheumatologist.
The following resources can help you get started talking to your patients about PsA.

Give the PEST to your patients. We encourage you to download the printable PDF, including the five-question quiz and diagram, and provide it to your psoriasis patients as part of their pre-appointment paperwork.
