Ventilator associated pneumonia (VAP) is a common hospital acquired pneumonia in ventilated patients. VAP is associated with increased morbidity, mortality duration of hospitalization and cost of treatment. Critical care nurses are usually unaware of evidence based preventive guidelines for VAP, resulting in negative impact on all aspects of patient care. This study investigated the impact of a 5-hour teaching module on nurses' knowledge to practice evidence based guidelines for the prevention of VAP.
This study was conducted at a private tertiary care teaching hospital in Karachi, Pakistan. Single group pre-test design was used. Forty nurses were included in the study. The knowledge of nurses was assessed before, immediately after and 4 weeks after the intervention. The final sample (n=40) was selected on the basis of the set inclusion criteria. The demographic data sheet was used to collect relevant information about the participants. Knowledge was assessed through a self-developed validated tool, consisting of multiple choice questions. The difference in knowledge was analysed through repeated measures of analysis of variance. The mean scores at 3 time points were compared using the Tukey's multiple comparison procedure.
Knowledge scores of participants increased significantly after the educational intervention in the first post-test; however, there was a decline in the score in post-test 2.
the 5-hour teaching module significantly enhanced nurses' knowledge towards evidence based guidelines for the prevention of VAP. Further research is needed to assess the impact of training on nursing practice and to explore factors affecting attitudinal change.
呼吸机相关性肺炎（VAP）是机械通气患者中常见的医院获得性肺炎。VAP与发病率增加、死亡率、住院时间延长及治疗费用增加相关。重症护理护士通常不了解基于证据的VAP预防指南，这对患者护理的各个方面都产生了负面影响。本研究调查了一个5小时教学模块对护士实践基于证据的VAP预防指南知识的影响。
本研究在巴基斯坦卡拉奇的一家私立三级护理教学医院进行。采用单组预测试设计。40名护士纳入研究。在干预前、干预后立即及干预后4周评估护士的知识水平。最终样本（n = 40）根据设定的纳入标准选取。使用人口数据表收集参与者的相关信息。通过一个自行开发的经过验证的工具（由多项选择题组成）评估知识水平。通过重复测量方差分析来分析知识水平的差异。使用Tukey多重比较程序比较3个时间点的平均得分。
在首次测试后，教育干预使参与者的知识得分显著提高；然而，在第二次测试中得分有所下降。
5小时教学模块显著提高了护士对基于证据的VAP预防指南的知识水平。需要进一步研究来评估培训对护理实践的影响，并探索影响态度改变的因素。
