The economic burden of stomas in the UK: a retrospective observational study of health records and hospital encounters

Abstract

Background: Stomas divert waste from the small intestine (ileostomy), large intestine (colostomy) or ureters (urostomy), and complications are common. Aims: This study evaluated healthcare resource utilisation (HCRU) and costs of stomas from a UK perspective. Methods: This was a retrospective observational study of adults with new stomas (New Stoma Group) or new/existing stomas and >6 months of follow-up (Established Stoma Group) using health records linked with hospital encounters (January 2009–December 2018). Age- and sex-matched controls were identified for each stoma case (1:50) Findings: Both the New (n=8533) and Established (n=9397) stoma groups had significantly higher HCRU (all P<0.0001) and associated costs (all P<0.01), driven by inpatient admissions. New Stoma Group: colostomy versus controls, £3227 versus £99 per person; ileostomy, £2576 versus £78 per person; and urostomy, £2850 versus £110 per person (all P<0.0001). Findings were similar in the Established Stoma Group. Conclusion: Stomas are associated with a substantial economic burden in the UK driven by hospital care.
