ABSTRACT
BACKGROUND:
Low tidal volume ventilation reduces mortality in patients with acute lung injury (ALI) and may reduce the risk of ALI in ventilated patients. A previous audit of our ventilation practices showed poor adherence to low tidal volume ventilation, and we subsequently introduced written ventilation guidelines and an education program to change practice.OBJECTIVES:
To determine if adherence to low tidal volume ventilation (defined as mandatory tidal volumes of =?6.5 mL/ kg predicted body weight [PBW]) in ventilated patients was improved with a written guideline and staff education. DESIGN ANDSETTING:
Retrospective analysis of recorded mandatory ventilator settings from the clinical information system of a tertiary referral intensive care unit from 1 January 2012 to 31 December 2015, involving analysis of mandatory ventilator settings in relation to PBW to determine adherence to guidelines, and interrupted time-series analysis to assess the impact of education. MAIN OUTCOMEMEASURE:
Adherence to low tidal volume ventilation.RESULTS:
The mean tidal volume for the cohort was 7.4 mL/ kg (SD, 1.3 mL/kg) PBW, and 760 patients (26.9%) received an average tidal volume during mandatory ventilation of ≤6.5 mL/kg PBW. Interrupted time-series analysis showed improved adherence after education, with an increase in adherence of 29.4% (95% CI, 19.3%-39.5%) from baseline. Multivariate logistic analysis found height, weight and staff education, but not sex, were associated with adherence to low tidal volume ventilation.CONCLUSION:
Written protocols and education can influence clinician behaviour, with substantial improvements in adherence to low tidal volume ventilation. Efforts to improve adherence through ward-based education appear warranted and necessary. Adherence was strongly associated with patient height, which suggested that adherence was partly the result of chance rather than design.
