✦ Synopsis

Background:

The aim was too describe the demographic characteristics of patients with inflammatory bowel disease (ibd) undergoing colonoscopy.

Methods:

The clinical outcomes research initiative (cori) maintains a database of endoscopic procedures in diverse clinical practices distributed throughout the us. the data from 2000-2007 were used to analyze the demographic characteristics of patients with crohn's disease (cd) and ulcerative colitis (uc).

Results:

During the period 2000-2007, 4631 patients with cd and 6619 patients with uc were compared to a control population of 826,207 patients without ibd. cd and uc patients were significantly (p < 0.0001) younger than controls: 41.7 ± 18.4, 47.3 ± 17.4, 59.2 ± 14.0 years, respectively. cd and uc were less common among nonwhite than white endoscopy patients: odds ratio (or) = 0.64 (0.58-0.70) for cd and or = 0.71 (0.66-0.77) for uc. endoscopy for ibd was only slightly less common among female than male cd patients (0.94, 0.89-1.00), but significantly less common among female than male uc patients (0.72, 0.68-0.75). compared with community/private practices, relatively more endoscopies were performed among ibd patients in academic institutions: or = 1.68 (1.56-1.81) for cd and or = 1.27 (1.19-1.36) for uc. the race-, sex-, and age-adjusted rates of cd and uc were both significantly higher in the northern than southern regions of the us, with a significant correlation of r = 0.89, degrees of freedom = 4, p = 0.017 between the geographic distributions of the two diagnoses.

Conclusions:

The endoscopy patterns of ibd patients may be influenced in part by the epidemiology of these two diagnoses, as well as by underlying trends in the utilization of colonoscopy.
