Diagnostic delay in patients with inflammatory bowel disease in Austria

A total of 1286 patients (Crohn’s disease 830, ulcerative colitis 435, inflammatory bowel disease unclassified 21; females 651) with a median age of 40 years (interquartile range 31–52 years) and a median disease duration of 10 years (4–18 years) were analyzed. The median diagnostic delay was 6 months (2–23 months) in Crohn’s disease and 3 months (1–10 months) in ulcerative colitis (p < 0.001). In the multivariable regression analysis Crohn’s disease, greater age at diagnosis and a high educational level (compared to middle degree level) were independently associated with longer diagnostic delay.
