摘要Community-acquired pneumonia(CAP)in adults(≥18 years old)is the most common infectious disease encountered in emergency de-partments.Its clinical complexity and the need for prompt treatment decisions pose significant challenges for patient management.The physician-pharmacist collaborative management(PPCM)model,which optimizes drug therapy regimens through collaboration between physicians and clinical pharmacists,has demonstrated strong clinical value in practice.However,the lack of standardized national guide-lines for the application of the PPCM model in emergency departments in China has hampered its widespread adoption.This guideline is developed based on evidence-based medicine and clinical practice experience,with a focus on the application of the PPCM model in the management of CAP in emergency settings.It outlines the significance of the PPCM model,its applicable scenarios,the respective roles of emergency physicians and clinical pharmacists,and its practical implementation in the antimicrobial treatment of CAP patients.In addition,the guideline proposes standardized implementation processes and clinical pathways.By promoting the PPCM model,the expert panel aims to standardize the use of antimicrobial agents in the emergency treatment of CAP,reduce the risk of antimicrobial resistance,and improve patient outcomes.
