Systematic review of patient-reported outcome measures (PROMs) is crucial for identifying high-quality PROMs for research and clinical practice. It ensures reliable health outcomes data collection. But current PROMs systematic review reports vary in quality and have many defects. To address this, in 2024, the guideline research team updated and published the COSMIN guideline V2.0 for PROMs systematic review and two other tools in the Quality of Life Research. This paper interprets the guideline development team, method, and the core content of the COSMIN guideline V2.0. It also uses specific examples to promote standardized PROMs selection and clinical application, aiming to help domestic researchers improve the quality of such systematic reviews.
Patient-reported outcome measures (PROMs) are instruments that capture patients’ perceptions of their health status and the benefits of treatment. The psychometric adequacy of these tools is therefore an empirical prerequisite. Nevertheless, published evaluations often omit critical details about measurement properties, and clinical trials rarely give a complete account of how PROMs were implemented. To close these gaps, the consensus-based standards for the selection of health measurement instruments (COSMIN) initiative has released version 2.0, a comprehensive update of the original COSMIN 1.0 guidance for PROMs research. This article walks readers through the COSMIN 2.0 checklist, illustrating each item with concrete examples.
