- W1500589159 abstract "Background: Patients undergoing mechanical ventilation are exposed to the risk of ventilator-associated pneumonia (VAP). Frequent ventilator circuit changes are expensive and unnecessary. We investigated whether extending ventilator circuit intervals from twice weekly to once weekly would impact VAP rates at our hospital.Methods: Prospective 2-year review of mechanically ventilated adult patients in the medical ICU, respiratory ICU, and general ward at Changhua Christian Hospital. The patients whose ventilator circuits were changed twice a week (at 3- or 4-days intervals) from January 1999 to June 1999 comprised the control group; those whose ventilator circuits were changed once a week from January 2000 to June 2000 formed the study group. There were 210 patients in the control group and 340 patients in the study group receiving mechanical ventilation. Ventilator-related pneumonia was diagnosed based on the criteria of the United States Centers for Disease Control (CDC). The incidence of VAP was determined in both groups.Results: In the control group, 20 patients developed VAP within 3,372 ventilator days, resulting in a rate of 5.93 per 1000 ventilator days. In the study group, 20 cases of VAP in 5,035 ventilator days resulted in a pneumonia rate of 3.97 per 1000 ventilator days. The difference between the groups was not statistically significant (relative risk 1.51; 95% confidence interval 0.81-2.80; p=0.196).Conclusions: Extending the intervals between ventilator circuit changes from twice a week to once a week does not increase the risk for VAP." @default.
