Background: Twenty percent of patients with ulcerative colitis (UC) face colectomy and therefore need to choose between restorative proctocolectomy with a pouch reconstruction or a permanent ileostomy. In order to provide patients and physicians with evidence-based information on both patient-reported outcomes and costs, we compared quality of life and total costs (healthcare costs and productivity costs) in patients with a pouch or ileostomy in a large unselected cohort with IBD patients in the Netherlands.

Methods: We obtained data from the ‘Cost of Inflammatory bowel disease in the Netherlands’ or COIN study, a prospective web-based 3 monthly questionnaire. We included all UC patients with a pouch and ileostomy at 3 months of follow up. The questionnaires contained questions on demographics, health care costs and productivity costs. Health-related quality of life was assessed using the EQ-5D. Costs were calculated by multiplying resource use by the unit costs as determined in the Dutch guidelines for pharmaco-economic analyses for the year 2009 by Oostenbrink et al.

Results: A total of 982 UC patients completed the follow up questionnaire at 3 months, of whom 77 patients (7.8%) had a pouch (57.1% males, mean age 46.8±12.4 years, mean disease duration 14.9±8.8) and 53 patients (5.4%) an ileostomy (54.7% males, mean age 52.7±11.3 years, mean disease duration 16.9±11.5). There was no statistically significant difference in health-related quality of life: mean EQ-5D utility for pouch was 0.85 (SD 0.19), and 0.85 (SD 0.17) for ileostomy. The mean (95% CI) costs per 3 months in patients with a pouch were significantly lower as compared to patients with an ileostomy, €929 (127–1732) versus €1282 (323–2242), respectively (p < 0.01). This was mainly due to higher healthcare costs caused by hospitalizations (2 (2.6%) versus 6 (11.3%)) among UC patients with an ileostomy as compared to UC patients with a pouch (€371 (76–666) versus €66 (27–160), p = 0.02).

Conclusions: We observed no difference in quality of life in patients with a pouch or ileostomy, but patients with a pouch had significantly lower total costs, mainly due to fewer hospitalizations.
