目的 调查临床护士给药中断事件发生现状并分析其影响因素，为改善护理服务质量提供依据。 方法 2024年3-4月，便利抽样法选取北京市某三级甲等综合性医院临床护士125名为研究对象，采用中文版工作场所中断测量量表、中文版护士用药安全能力量表等对其进行调查，并分析给药中断事件发生的影响因素。 结果 有85.6%（107/125）的护士在给药过程中意识到中断事件的发生。多元线性回归分析结果显示，护士用药安全能力、学历、给药中断事件了解程度是护士给药中断事件发生的负向影响因素，任务负荷指数是护士给药中断事件发生的正向影响因素，该模型可解释给药中断事件24.3%的变异。 结论 护士给药中断事件发生频率处于中高水平，护理管理者应关注并识别给药中断事件的影响因素，制定个性化的干预措施，减少给药中断事件的发生。
