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, 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.

结局测量工具（OMI）是评估患者感受或健康状况的重要工具，但其质量参差不齐。选择健康测量工具的共识标准（COSMIN）为遴选高质量的OMI提供了方法学指导，得到广泛认可。近年来，基于COSMIN开展的OMI系统评价数量激增，然而许多已发表的相关系统评价常未能充分报告关键信息，严重影响了OMI系统评价的可重复性和可解释性，从而影响其结果的推广应用。鉴于PRISMA 2020未包含报告此类系统评价的所有必要信息，有关学者在前者基础上制订了新的报告规范"PRISMA-COSMIN for OMIs 2024"，以帮助研究人员以清晰、详细和透明的方式撰写和报告OMI系统评价。本文结合实例对该规范进行了介绍和解读，旨在帮助国内学者深入理解并有效应用该指南，提高国内OMI系统评价进行全面地的整体质量。
