FAQ: Screening Tools APPs Use to Identify PsA, SpA, or IBD and Refer Early

February 2026

Delayed diagnosis in psoriatic arthritis (PsA), spondyloarthritis (SpA), and inflammatory bowel disease (IBD) can lead to irreversible damage and prolonged patient suffering. In this FAQ episode, host Audrey Gibson, PA-C reviews validated screening tools that help clinicians identify these conditions earlier and determine when referral to rheumatology or gastroenterology is warranted.

The discussion highlights practical screening strategies for frontline providers, including the Psoriasis Epidemiology Screening Tool (PEST) for identifying PsA risk in patients with psoriasis, as well as referral criteria for spondyloarthritis based on inflammatory back pain features and ASAS recommendations. Key red flags such as early-onset chronic back pain, morning stiffness, extra-articular symptoms, and family history are reviewed.

For gastrointestinal symptoms, the episode explores how tools like CalProQuest and alarm features such as chronic diarrhea, rectal bleeding, anemia, and weight loss can help distinguish IBD from functional GI disorders. This FAQ offers practical guidance to shorten diagnostic delays, support timely referrals, and improve long-term outcomes. Learn more on the RhAPP Content Rheum or in the RhAPP ACE App.
