目的：通过调查了解消化科护士对幽门螺旋杆菌(Hp)感染的认知程度，并分析其影响因素，以期为消化科护士普及Hp相关知识，有针对性地改善临床Hp感染护理质量提供数据支撑。方法：应用基本资料调查表、Hp感染认知程度调查问卷进行随机抽样调查，调查内容包括Hp基本知识、预防、危害、治疗与管理等4个维度，共25个条目。采用独立样本t检验或ANOVA单因素方差分析进行单因素分析，采用多元性线性回归分析不同变量对Hp认知水平的影响。结果：共调查 442名消化科护士，有效回收问卷365份。多元线性回归分析显示从业年限<1年、护患比>1∶6、未担任科研工作、未阅读美国胃肠病学院(ACG)指南或Hp感染相关文献及专家共识声明、未参加Hp感染护理实践、既往1年内未参加Hp感染护理培训的消化科护士对Hp感染认知得分更低。结论：消化科护理人员对Hp感染的认知程度仍不足，应有针对性地制定多种策略，消除障碍性因素，从而改善临床护理。
