To assess the effectiveness of the ventilator bundle in the reduction of mortality in ICU patients.
PubMed, Scopus, Web of Science, Cochrane Library for studies published until June 2017.
Included studies: randomized controlled trials or any kind of nonrandomized intervention studies, made reference to a ventilator bundle approach, assessed mortality in ICU-ventilated adult patients.
Items extracted: study characteristics, description of the bundle approach, number of patients in the comparison groups, hospital/ICU mortality, ventilator-associated pneumonia–related mortality, assessment of compliance to ventilator bundle and its score.
Thirteen articles were included. The implementation of a ventilator bundle significantly reduced mortality (odds ratio, 0.90; 95% CI, 0.84–0.97), with a stronger effect with a restriction to studies that reported mortality in ventilator-associated pneumonia patients (odds ratio, 0.71; 95% CI, 0.52–0.97), to studies that provided active educational activities was analyzed (odds ratio, 0.88; 95% CI, 0.78–0.99), and when the role of care procedures within the bundle (odds ratio, 0.87; 95% CI, 0.77–0.99). No survival benefit was associated with compliance to ventilator bundles. However, these results may have been confounded by the differential implementation of evidence-based procedures at baseline, which showed improved survival in the study subgroup that did not report implementation of these procedures at baseline (odds ratio, 0.82; 95% CI, 0.70–0.96).
Simple interventions in common clinical practice applied in a coordinated way as a part of a bundle care are effective in reducing mortality in ventilated ICU patients. More prospective controlled studies are needed to define the effect of ventilator bundles on survival outcomes.
