ABSTRACT
@#Recent studies have shown that educational interventions for ventilator-associated pneumonia (VAP) prevention may result in positive outcomes in intensive care units. However, other studies investigating this kind of intervention have produced inconsistent results. Thus this paper reports a protocol for systematic review and planned meta-analysis to investigate the association of instituted VAP educational interventions with clinician learning and patient outcomes. In this review, the authors will identify relevant citations from electronic databases, reference lists, and other sources; screen articles against predetermined eligibility criteria; appraise each study using the Cochrane Collaboration’s risk of bias assessment tools and combine acquired evidence using the meta-analytic approach. The results of this review are crucial to assist clinicians and policy-makers in making well-informed decisions regarding VAP prevention practices for mechanically ventilated patients. This review protocol followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses for Protocols 2015 guidelines and was registered with PROSPERO as CRD42016051561.

ABSTRACT The effectiveness of prevention bundles on the occurrence and mortality of ventilator associated pneumonia (VAP) was evaluated in many studies. However, the effectiveness of endotracheal tube with subglottic secretion drainage (ETT-SD) and cuff pressure monitorization in VAP bundles have not been adequately assessed. In this study, we aimed to evaluate the effectiveness of VAP bundle containing ETT-SD and cuff pressure monitorization. This was a prospective, controlled study that was carried out between March 2011 and April 2012 including intubated patients. The study was conducted at the Anesthesiology Intensive Care Unit 1 and 2 (10 beds each) in a 898-bed university hospital. Occurrence of VAP and compliance with the parameters of the VAP prevention bundles were assessed daily. Patients intubated with the standard endotracheal tube were recruited as controls, mainly in the first six months of the study as ETT-SD and cuff pressure monometer had not yet been implemented. In the second term, patients intubated with ETT-SD were included as cases. Occurrence of VAP, mortality, and compliance with VAP prevention bundles were monitored. A total of 133 patients, 37 cases and 96 controls were recruited. VAP incidence declined from 40.82 to 22.16 per 1000 ventilator days among controls and cases, respectively (p < 005). On average, VAP occurred 17.33 ± 21.09 days in the case group and 10.43 ± 7.83 days in the control group (p = 0.04). However, mortality of cases and controls at the 14th and 30th days was not different. VAP prevention bundles including the utilization of ETT-SD, monitoring cuff pressure, and oral care with chlorhexidine were efficient in reducing the rate of VAP.
