Predictors of Perceived Practice in Ventilator-Associated Pneumonia (VAP) Prevention Among Critical Care Nurses in Sarawak Public Hospitals
Background and objective Ventilator-associated pneumonia (VAP), a leading cause of ICU mortality, remains prevalent in Southeast Asia, with limited data on critical care nurses’ knowledge and prevention practices in Malaysia. The purpose of this study was to assess knowledge, practices, barriers, and predictors of VAP prevention among critical care nurses in Sarawak, Malaysia. Methods This cross-sectional study was conducted from July to August 2023 at four public hospitals in Sarawak, Malaysia. Universal sampling was used to recruit nurses from various critical care units managing patients requiring ventilator support. A self-administered questionnaire, consisting of four sections, was employed to gather background information from nurses, assess their knowledge, perceived practices, and identify barriers related to VAP prevention. Results A total of 298 critical care nurses participated in the study. Of these, 66.8% demonstrated poor knowledge of ventilator-associated pneumonia (VAP) prevention; however, compliance with VAP prevention practices was significantly high at 76.5%. A Pearson's correlation test revealed a significant association between the nurses' knowledge and their practices related to VAP prevention (p<0.001). Additionally, multiple regression analyses identified several significant predictors of critical care nurses’ perceived practices in VAP prevention, including their level of knowledge, type of unit, number of official beds, and sociodemographic factors (p <0.05). While knowledge positively influenced perceived practice, its impact was relatively minor compared to sociodemographic factors. Barriers to VAP prevention included nursing staff shortages, forgetfulness, and lack of written protocols. Conclusions The prevention of ventilator-associated pneumonia (VAP) is a multidisciplinary challenge, emphasizing the crucial role of critical care nurses. The findings from this study underscore the necessity for updated, evidence-based interventions that target knowledge gaps, perceived practices, and barriers to effective VAP prevention.
