Condition
Ankylosing spondylitis (AS), early axial spondyloarthritis (axial SpA)
Intervention
Experimental group (no medical intervention):
The diagnostic accuracy of IBP will be investigated in four private practices and two hospitals by assessing IBP by an independent and blinded observer (rheumatologist in each setting) in patients with undiagnosed chronic back pain who are referred because of suspected SpA.
IBP will also be assessed by primary care physicians or orthopaedists in patients with chronic back pain of unclear origin, and also self-assessed by the patient prior to referral to the Rheumatology Department at Charité CBF for further work-up.
The total duration of the trial is two years. There is no follow-up.
Intervention type
Other
Primary outcome measure
Sensitivity, specificity and positive likelihood-ratio (LR+) if two out of four parameters of IBP are present.
Secondary outcome measures
Sensitivity, specificity and positive likelihood-ratio (LR+) if three or four out of four parameters of IBP are present.
