The British Axial Spondyloarthritis Cohort (BAxSIC) study has been established under the auspices of the British Society for Spondyloarthritis (BRITSpA) in collaboration with the National Axial Spondyloarthritis Society (NASS) to provide real-world data on the impact of diagnostic delay on work participation and other outcomes in people affected with axial Spondyloarthritis in the UK.

The BAxSIC study is a prospective, inception cohort enrolling patients attending rheumatology clinics in the UK who are newly diagnosed with axSpA. BAxSIC is largely a virtual study with the majority of data being inputted online by the study participants.
