A large patient cohort study suggests that the mean diagnostic delay (DD) in European axial spondyloarthritis (axSpA) patients is 7.4 years, moreso in women and younger patients.
An online survey of 2,652 patients from 13 countries (European Map of Axial Spondyloarthritis - EMAS) asked patients about their onset of symptoms and the time it took ot diagnose axSpA) and found that the average DD was 7.4 ± 8.4 years.
