Interpretation of the Reporting Guideline for Systematic Reviews of Outcome Measurement Instruments (PRISMA-COSMIN for OMIs 2024) postprint

Abstract: Outcome Measurement Instruments（OMI）are essential tools for evaluating patients’ experiences or health status，but their quality levels often vary. The COnsensus-based Standards for the selection of health Measurement INstruments（COSMIN）provide methodological guidance for selecting high-quality OMIs，which is widely recognized. In recent years，there has been a sharp increase in the number of systematic reviews of OMI based on COSMIN. However，many published related systematic reviews often fail to fully report key information，significantly impacting the reproducibility and interpretability of such systematic reviews，thus affecting the dissemination and application of their results. As the PRISMA 2020 does not include all necessary information for reporting such systematic reviews，the scholars have developed a new reporting standard，“PRISMA-COSMIN for OMIs 2024”，to assist researchers in writing and reporting systematic reviews of OMI in a clear，detailed，and transparent manner. This article introduces and interprets this guideline through an example paper，aiming to help domestic scholars better understand and effectively apply the guideline，thereby enhancing the overall quality of systematic reviews of OMI conducted in China.
