Evaluation of patient-reported outcome measures in intermittent self-catheterization users: A systematic review

Abstract Objective: To identify patient-reported outcome measurements (PROMs) for intermittent self-catheterization (ISC) users, critically assess and summarize the quality of the measurement properties, and describe the application scenarios on each instrument. Data Sources: PubMed, EMBASE, Medline, PsycINFO and relevant reference lists were systematically searched until December 2019 (updated May 2020). Study selection: Two reviewers independently identified original English language publications that evaluated the psychometric properties of specific PROMs used in ISC patients. Data extraction: The following data were obtained: author and publication year, content of domains/subscales, number of items, response options, constructs measured, language and information on measurement properties. Data synthesis: Eleven publications were deemed eligible, including 6 PROMs for measuring patients' ISC-related quality of life, self-confidence, satisfaction, difficulties, acceptance and adherence to treatment. The Intermittent Self-Catheterization Questionnaire provided the most detail, and the Intermittent Catheterization Acceptance Test could be evaluated on the most COSMIN properties. Conclusion: Several tools are available for ISC users, but at present there is no comprehensive, concise and robust instrument with good psychometric properties. Further research on psychometric properties is needed to verify the remaining properties of existing scales and to develop novel tools for clinicians, researchers and patients.
