Assessment of Knowledge and Compliance to Evidence-Based Guidelines for VAP Prevention among ICU Nurses in Tanzania

Abstract Background: Implementation of evidence-based guidelines (EBGs) related to VAP is an effective measure for the prevention of ventilator-associated pneumonia (VAP). While low knowledge regarding the EBGs related to VAP prevention among ICU nurses is still a major concern among nurses in ICUs globally, the situation in Tanzania is scarcely known. This study aimed to assess the ICU nurses’ knowledge, compliance, and barriers toward evidence-based guidelines for the prevention of VAP in Tanzania. Methods: A cross-sectional study, involving ICU nurses of major hospitals in Tanzania, was conducted. A structured questionnaire was administered among 116 ICU. Data analysis included descriptive statistics and independent t-test. Results: The mean knowledge score was 38.6% which is lower than the lowest ever reported knowledge score for EBGs for VAP prevention. Nurses with a degree or higher level of nursing education performed significantly better than the nurses with a diploma or lower level of nursing education(p=0.004). The mean self-reported adherence score for EBGs for the prevention of VAP was 60.8%. The main barriers to the implementation of EBGs for VAP prevention were lack of skills (96.6%), lack of adequate staff (95.5%), and lack of knowledge (79.3%). Conclusion: Considering the severity and impact of VAP, and the higher risks of HAIs in resource-limited countries like Tanzania, the lower level of knowledge and compliance implies the need for on-going educational interventions and evaluation of the implementation of the EBGs for VAP prevention by considering the local context.
