摘 要
呼吸机相关性肺炎（VAP）是重症监护病房中常见的并发症，严重影响患者预后并增加医疗成本。为探讨循证护理在预防VAP中的作用，本研究基于循证医学理念，通过系统评价和me ta分析方法，综合国内外最新研究成果，制定并实施了一套完整的循证护理干预方案。该方案涵盖气道管理、体位护理、口腔护理、营养支持等多方面内容，并引入了风险评估工具和质量控制体系。研究选取某三甲医院ICU病房2019年1月至2021年12月期间收治的486例使用机械通气患者作为研究对象，按照随机数字表法分为对照组和实验组各243例，对照组采用常规护理措施，实验组在常规护理基础上实施循证护理干预。结果显示，实验组VAP发生率显著低于对照组（P0.05），平均带机时间缩短约2.7天，住院日减少3.2天，抗生素使用时长减少4.1天，医疗费用降低约15%。此外，实验组患者家属满意度评分明显高于对照组（P0.05）。本研究创新性地将循证护理理念与临床实践紧密结合，构建了科学合理的预防VAP护理模式，为临床护理工作提供了理论依据和技术支持，对提高医疗质量、保障患者安全具有重要意义。

Abstract
Ventilator-associated pneumonia (VAP) is a common complication in intensive care units, significantly affecting patient outcomes and increasing healthcare costs. To investigate the role of evidence-based nursing in preventing VAP, this study adopted the principles of evidence-based medicine and utilized systematic review and me ta-analysis methods to synthesize the latest domestic and international research findings, thereby developing and implementing a comprehensive evidence-based nursing intervention program. This program encompassed multiple aspects including airway management, positioning care, oral hygiene, and nutritional support, while incorporating risk assessment tools and quality control systems. The study selected 486 mechanically ventilated patients admitted to the ICU of a tertiary hospital from January 2019 to December 2021 as subjects, dividing them into control and experimental groups of 243 patients each using a random number table method. The control group received routine nursing care, whereas the experimental group underwent evidence-based nursing interventions in addition to routine care. Results demonstrated that the VAP incidence rate in the experimental group was significantly lower than in the control group (P0.05), with a reduction of approximately 2.7 days in average ventilation duration, 3.2 days in hospital stay, and 4.1 days in antibiotic usage duration. Medical expenses were reduced by about 15%. Additionally, family satisfaction scores for patients in the experimental group were significantly higher than those in the control group (P0.05). This study innovatively integrated evidence-based nursing concepts with clinical practice, establishing a scientifically sound and rational VAP prevention nursing model, providing theoretical basis and technical support for clinical nursing work, and playing a significant role in improving medical quality and ensuring patient safety.
