Clinical practice guidelines serve as a crucial bridge linking research evidence, clinical practice, and health policy decision-making. However, the guideline domain continues to face persistent challenges, including duplicate guideline development, variable methodological quality, lack of transparent reporting, insufficient implementation and translation, and delayed updates. Focusing solely on "how to develop a high-quality guideline" is no longer sufficient to meet the modern healthcare system's demands for timely, trustworthy, actionable, and dynamically updated recommendations. The emergence of the guideline ecosystem marks a shift in guideline research and practice from a linear development process toward a more systematic governance model. Rooted in the evidence ecosystem, the guideline ecosystem has its own distinct functional positioning, encompassing recommendation formulation, clinical implementation, and life-cycle updating. Looking ahead, China should leverage guideline registries, integrated quality assessment systems, implementation science, dynamic updating mechanisms, and artificial intelligence technologies to promote the transformation of its guideline system from scale expansion to an ecosystem-based model characterized by high quality and sustainability.

The importance of consensus research in medical decision-making has become increasinglyprominent. However, this field has long lacked unified terminology definitions and reporting standards, leading to significant heterogeneity in study design, implementation, and result presentation that affects the credibility and reproducibility of outcomes. The ACCurate COnsensus Reporting Document (ACCORD) in the field of biomedical research provides a structured writing framework for various consensus methods such as the Delphi method and nominal group technique, aiming to enhance the completeness and transparency of study reports. Combined with specific cases, this article interprets the core items of ACCORD, offering references for the design, implementation, and reporting of high-quality consensus research in China.
