Title: Spondyloarthritis Including PsA – Diagnosis, Manifestations, and Outcomes Poster I

Session Type: Poster Session A

Session Time: 1:00PM-3:00PM

Background/Purpose: Clinicians face uncertainties in their daily practice when requesting imaging for patients with suspicion of axial spondyloarthritis (axSpA) or producing a report because requirements and desired information of the other disciplines is sometimes not completely known or understood. This project aimed to develop easy-to-follow consensus recommendations for the standardized communication around imaging of sacroiliac joints and spine for diagnosis in patients with suspected axSpA or its management in clinical practice.

Methods: A task force was established combining radiologists and rheumatologists from the Assessment of SpondyloArthritis international Society (ASAS), two members of young-ASAS and a patient representative. The task force defined the project’s aims and developed a project statement. Then, under the reflection of the literature and work of other groups, two survey rounds were designed, and all ASAS members invited to respond: first, to identify items for further consideration, second, to consider the detail of information to be transferred. Finally, ASAS members discussed the recommendations during the ASAS annual workshop in January 2022 and voted for the endorsement.

Results: The recommendations were endorsed by ASAS with approval from 73% of voting members. The final set of recommendation is presented in Figure 1. Six recommendations deal with imaging requests in patients with axSpA. The first three cover clinical features, patients’ symptoms and risk factors. Recommendations 4 involves previous imaging and reports, 5 contraindications to imaging or contrast media. Number 6 is about the suspected diagnosis, the reason for the exam, and clinical differential diagnoses. Eleven recommendations refer to the radiology report. The first point addresses clinical information included in the report. Recommendations 2 to 4 instruct on information about the technical conduct of the exam, the use of contrast media and image quality. Necessary imaging findings to be included in the report are listed in recommendations 5 to 7. Finally, recommendations 8 to 11 combine advice for the conclusion, for suggesting additional imaging or referral to a rheumatology expert if a different physician requested the imaging.

Conclusion: The ASAS recommendations provide guidance for requesting and reporting imaging in axSpA and for standardizing communication between rheumatologists and radiologists to improve diagnosis and patient care.
