Résumé
6.9 years: this is the average delay in France for the diagnosis of spondyloarthritis. The sex ratio seems to be balanced, although there is a difference in the time taken to diagnose the disease between the two sexes. It has been established that on average it takes 6.5 years for a man to be diagnosed with this disease, compared to 8.8 years for a woman. The stakes in making the diagnosis are therefore crucial. However, no symptom is pathognomonic of this pathology and does not allow an instant diagnosis. The pathophysiology is complex, the differential diagnosis is important and the diagnostic process is laborious. How can this delay in diagnosis be explained and is there a difference between the sexes? If so, how can this delay be remedied? The aim of this thesis was to understand the differences and difficulties that lead to such a long delay.Through this thesis, the diagnosis of spondyloarthritis will be analyzed and new opportunities for access to care will be proposed in the hope of helping to reduce this delay.First, a description of the disease is given, followed by an analysis of the impact of gender through the differences known to date between men and women.The last part will propose areas for improvement to potentially help reduce this erratic behavior.
