The selection of outcome measurement instruments (OMI) is a prerequisite for accurately collecting health outcome data. Conducting a systematic review of OMI can provide an important reference for researchers and practitioners to select the most appropriate OMI. In order to improve the reporting quality of the systematic review of OMI, foreign researchers published the PRISMA-COSMIN reporting guideline in the J Clin Epidemiol in June 2024. This article introduces the research team, development process, and items of the reporting guideline, and analyzes the items with examples. We hope our attempt could help domestic researchers improve the overall quality of OMI systematic reviews.
