RESUMO
BACKGROUND/OBJECTIVE: The diagnostic delay of axial spondyloarthritis (axSpA) is globally reported to be between 3 and 11 years. Early diagnosis and treatment have long-term benefits for patients and the health care system. Several international studies have evaluated some factors associated with diagnostic delay, but there are no known studies in the Colombian population. This study assesses the factors associated with diagnostic delay of axSpA in a rheumatology center in Bogota, Colombia. METHODS: This monocentric analytical cross-sectional study was done in a specialized rheumatology center. Patients who fulfilled the 2009 Assessment of Spondyloarthritis International Society (ASAS) classification criteria for axSpA were included. Information was obtained from medical records and a phone call. Bivariate and multivariate analyses were done to assess the associated factors with diagnostic delay. RESULTS: One hundred one patients were included, 54 were women (53.5%). The median diagnostic delay was 2 years (interquartile range, 1-7). The bivariate analysis showed that a younger age at diagnosis (p = 0.042) and previous diagnosis of lumbar degenerative disease (p = 0.029) were associated with a longer diagnostic delay. The logistical regression showed that previous lumbar degenerative disc disease (odds ratio, 2.8; 95% confidence interval, 1.09-7.53) and fibromyalgia (odds ratio, 4.0; 95% confidence interval, 1.2-13.1) diagnosis were both associated with a longer diagnostic delay. CONCLUSIONS: Factors associated with a longer diagnostic delay were previous diagnosis of lumbar degenerative disc disease and fibromyalgia. Additional studies are needed so that the reasons for diagnostic delay are understood and early diagnosis and management of axSpA are enabled.
