TO THE EDITOR:
We read with interest the article by Kollef and colleagues on circuit changes and ventilator-associated pneumonia . This work was intended to confirm our finding that a ventilator circuit may be used throughout the mechanical ventilation of a patient without adverse effects . Unfortunately, their study design precludes this conclusion. The fact that no difference was found between the incidence of pneumonia in patients allocated to a 7-day change and that in patients given no change does not imply that prolonged use of a single ventilator circuit is safe. A group receiving 48-hour circuit changes (current practice in most U.S. hospitals) should have been included so that such a conclusion could be established. A greater incidence of pneumonia associated with 7-day changes than with 48-hour changes may have been overlooked in Kollef and colleagues' study. To our knowledge, only three studies published in full-length form clearly show that prolonged circuit use is safe [2-4].
