To investigate the impact of 1-week ventilator circuit change on ventilator-associated pneumonia and its cost-effectiveness compared with a 2-day change.
An observational cohort study.
A tertiary level neonatal intensive care unit in a university-affiliated teaching hospital in Taiwan.
All neonates in the neonatal intensive care unit receiving invasive intubation for more than 1 week from July 1, 2011, through December 31, 2013.
We investigated the impact of 2 ventilator circuit change regimens, either every 2 days or 7 days, on ventilator-associated pneumonia of our cohort.
Measurements and Main Results
A total of 361 patients were maintained on mechanical ventilators for 13,981 days. The 2 groups did not differ significantly in any demographic characteristics. The rate of ventilator-associated pneumonia was comparable between the 2-day group and the 7-day group (8.2 vs 9.5 per 1,000 ventilator-days, P=.439). The durations of mechanical ventilation and hospital stay, and rates of bloodstream infection and mortality, were also comparable between the 2 groups. Switching from a 2-day to a 7-day change policy would save our neonatal intensive care unit a yearly sum of US $29,350 and 525 working hours.
Decreasing the frequency of ventilator circuit changes from every 2 days to once per week is safe and cost-effective in neonates requiring prolonged intubation for more than 1 week.
