Psoriatic Arthritis Screening Tool For Providers

Early diagnosis of psoriatic arthritis leads to better long-term health. Patients who wait even as little as six months before getting diagnosed and starting treatment typically 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.

The Psoriasis Epidemiology Screening Tool, or PEST, is a screening tool that can help you recognize signs of psoriatic arthritis in your psoriasis patients1. Patients answer five questions and fill out a diagram.  If patients check “yes” to three or more of the questions, they may have psoriatic arthritis.  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 psoriatic arthritis.

Patient Appointment Resource Document

Give the PEST to your patients.  We encourage you to download the printable PDF, including five-question quiz and diagram, and provide it to your psoriasis patients as part of their pre-appointment paperwork. This will help them—and you—understand if they’re showing symptoms of psoriatic arthritis and whether they should be referred to a rheumatologist.
