Background: Ventilator associated pneumonia (VAP) is a common hospital acquired pneumonia inventilated patients. VAP is associated with increased morbidity, mortality duration of hospitalizationand cost of treatment. Critical care nurses are usually unaware of evidence based preventiveguidelines for VAP, resulting in negative impact on all aspects of patient care. This studyinvestigated the impact of a 5-hour teaching module on nurses’ knowledge to practice evidencebased guidelines for the prevention of VAP. Methods: This study was conducted at a private tertiarycare teaching hospital in Karachi, Pakistan. Single group pre-test post-test design was used. Fortynurses were included in the study. The knowledge of nurses was assessed before, immediately afterand 4 weeks after the intervention. The final sample (n=40) was selected on the basis of the setinclusion criteria. The demographic data sheet was used to collect relevant information about theparticipants. Knowledge was assessed through a self-developed validated tool, consisting of multiplechoice questions. The difference in knowledge was analysed through repeated measures of analysisof variance. The mean scores at 3 time points were compared using the Tukey’s multiple comparisonprocedure. Results: Knowledge scores of participants increased significantly after the educationalintervention in the first post-test; however, there was a decline in the score in post-test 2.Conclusion: The 5-hour teaching module significantly enhanced nurses’ knowledge towardsevidence based guidelines for the prevention of VAP. Further research is needed to assess the impactof training on nursing practice and to explore factors affecting attitudinal change.Keywords: Critical care, Pneumonia, Ventilator associated pneumonia, evidence based practice, nurses’knowledge
