What this trial studies

The British Axial Spondyloarthritis Inception Cohort (BAxSIC) aims to gather real-world data on the impact of delayed diagnosis of axial spondyloarthritis (axSpA) on work participation and functional outcomes. This prospective cohort study will enroll patients who have been newly diagnosed with axSpA and are naïve to biologic therapy, assessing various factors such as disease activity, pain, fatigue, and comorbidities over an initial three-year period. The study is conducted in collaboration with the British Society for Spondyloarthritis and the National Axial Spondyloarthritis Society, focusing on patients attending rheumatology clinics in the UK.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 16 and older who have received a physician diagnosis of axSpA within the last six months.

Not a fit: Patients under 16 years of age or those unable to communicate in English may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights that improve diagnosis and management of axial spondyloarthritis, potentially enhancing patient outcomes.

How similar studies have performed: Other studies have shown success in utilizing real-world data to evaluate the impact of delayed diagnosis in similar conditions, indicating that this approach is promising.
