Abstract: This article provides a systematic interpretation and review of the Society of Critical Care Medicine 2024 Guidelines on Adult ICU Design. Developed based on the Grading of Recommendations Assessment, Development and Evaluation methodology, the guideline address five core themes:ICU lay- out, room design, infection control, infrastructure, and staff spaces, and put forward 17 evidence- based recommendations, including 5 good practice statements. This article briefly introduces the guideline development methods and evidence characteristics, and focuses on summarizing key recommendations, in- cluding high-visibility layouts, single-bed ward settings, natural lighting and noise reduction strategies, inte- grated infection prevention and control design, remote monitoring, and flexible capacity expansion capabilities. Furthermore, it delves into the applicability and localized implementation pathways within China's healthcare environment, analyzing limitations in terms of evidence quality, specialty applicability, and cost-effectiveness. Furthermore, by integrating the Chinese Guidelines for the Construction and Development of Critical Care Medi- cine (2025 Edition) and current domestic practices, the article proposes tiered and phased implementation rec- ommendations. This article aims to provide domestic healthcare institutions with a scientific reference that bal- ances international cutting-edge concepts with China's real-world conditions for the construction and renovation of ICUs, thereby promoting the development of intensive care environments centered on patient safety, health- care worker well-being, and infection control.
