Evaluation of Patient-Reported Outcome Measures in Intermittent Self-Catheterization Users: A Systematic Review

To identify patient-reported outcome measures (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.

PubMed, EMBASE, Medline, PsycINFO, and relevant reference lists were systematically searched through December 2019 (updated May 2020).

Two reviewers independently identified original English language publications that evaluated the psychometric properties of specific PROMs used in ISC patients.

The following data were obtained: author and publication year, content of domains and subscales, number of items, response options, constructs measured, language, and information on measurement properties.

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 consensus-based standards for the selection of health status measurement instrument properties.

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.
