目的 调查ICU护士的谵妄护理能力的现状，分析和探讨ICU护士的谵妄护理能力的影响因素。 方法 采用便利抽样法，选取2024年1月—5月浙江省5所综合医院的ICU护士作为研究对象，使用一般资料调查表、中文版护士谵妄护理能力量表进行横断面调查，分析ICU护士谵妄护理能力的现状，采用单因素分析、多元线性回归分析探索影响护士谵妄护理能力的相关因素。 结果 ICU护士谵妄护理能力总分为（88.41±15.11）分，其中管理流程维度中的各条目得分最低，为（3.15±0.75）分，预防维度中各条目的得分最高，为（3.35±0.62）分；影响因素分析结果显示，所在医院等级、是否为专科护士和是否参加过谵妄相关培训是ICU护士谵妄护理能力的主要影响因素（P<0.05）。结论 ICU护士的谵妄护理能力的整体水平较高，但在管理流程方面仍有待进一步提高；所在医院等级、是否为专科护士和是否参加过谵妄相关培训是影响ICU护士谵妄护理能力的主要因素，不同维度影响因素有所差异，应采取针对性的提升策略。

Objective To survey the current status of ICU nurses’ competency in delirium care，and to analyze and explore the influencing factors of ICU nurses’ delirium care competency. Methods A convenience sampling method was used to select ICU nurses from five general hospitals in Zhejiang Province from January to May 2024 as the study subjects. A cross-sectional survey was conducted using the general information questionnaire and the Chinese version of the Nurse Delirium Competence Care Scale as research tools. The current status of nurses’ delirium care competency was analyzed，and univariate analysis and multiple linear regression analysis were used to explore the related factors influencing nurses’ delirium care competency. Results The total score of nurses’ delirium care competency was（88.41 ± 15.11）. Among the dimensions，the scores for items in the management process dimension were the lowest at（3.15 ± 0.75），while the scores for items in the prevention dimension were the highest at（3.35 ± 0.62）. The analysis of influencing factors showed that the degree of hospital，whether the nurse was a specialist nurse，and whether the nurse had participated in delirium-related training were independent influencing factors of nurses’ delirium care competency（P<0.05）. Conclusion The overall level of delirium care competency among ICU nurses is relatively high，but there is still room for improvement in the management process dimension. The degree of hospital，whether the nurse is a specialist nurse，and whether the nurse has participated in delirium-related training are the main factors influencing nurses’ delirium care competency. Different dimensions are affected by different factors，and targeted improvement strategies should be adopted.
