Development, validation and application of a ventilator-associated pneumonia prevention checklist in a single cardiac surgery centre

Abstract

ObjectivesThe purpose of this study was to develop, validate and apply a ventilator-associated pneumonia prevention checklist in a single cardiac surgery centre. MethodsAn initial checklist was designed based on the published care bundles for prevention of ventilator-associated pneumonia; the Delphi method used for validation. A total of 20 experts were invited to score the items and give suggestions for the checklist. The final checklist was then applied to patients receiving cardiac surgery. Non-compliance with the protocol and outcome indicators were observed. ResultsTwo rounds of Delphi were conducted. The final one-page checklist consisted of three main parts: (1) demographic data of the patient receiving cardiac surgery; (2) general assessment of the patient (3) checklist of prevention measures. The average time to complete the checklist was between two and four minutes. After the application of the checklist, the incidence of ventilator-associated pneumonia decreased from 14.48 to 5.47 episodes per thousand ventilator hours. In patients requiring >48 hours mechanical ventilation, the ventilator-associated pneumonia rate and duration of ventilation was significantly decreased. ConclusionA checklist was developed for ventilator associated pneumonia based on care bundles and validated using the Delphi method. The checklist appeared to be a useful tool in preventing ventilator associated pneumonia and shortening the ventilation time.
