Patient reported outcome measures assessing quality of life in patients with an intestinal stoma: A systematic review

AIM: Living with a stoma can greatly influence quality of life. The purpose of this systematic review was to identify all patient reported outcome measures (PROMs) assessing health related quality of life (HRQoL) or similar constructs related to an intestinal stoma and to evaluate their level of validation. METHODS: The study was reported in line with PRISMA guidelines. The protocol was registered in PROSPERO prior to the study. Eligible studies were any study investigating psychometric properties of a stoma‐specific PROM. The databases MedLine, Embase, CINAHL and Cochrane Libraries were searched for eligible studies. Studies were screened on title and abstract, then full‐text for eligibility. Data extraction on the study populations, PROM characteristics, psychometric properties as well as quality assessment using the COSMIN Risk of Bias checklist was performed. RESULTS: In total, 40 studies were included concerning the development and/or validation of 21 PROMs. For most PROMs, few psychometric properties were assessed. In general, quality of content validity was poor, quality of construct validity and reliability was good. Assessment of responsiveness was lacking. CONCLUSION: This systematic review offers an overview of existing PROMs measuring stoma‐related HRQoL and their psychometric properties. A large number of PROMs exist and their measures overlap considerably. The PROMs generally have a low level of validation, emphasizing the need for future studies to further validate existing PROMs, rather than developing new ones.
