There are few reports in Japan on the new ventilator-associated event (VAE) surveillance proposed by the Centers for Disease Control and Prevention in 2013. We conducted VAE surveillance and conventional ventilator-associated pneumonia (VAP) surveillance on patients aged >18 years who were on mechanical ventilation in the intensive care unit (ICU) at the Niigata University Medical and Dental Hospital and retrospectively compared their clinical features. Of the 290 cases, 14 of ventilator-associated conditions, 7 of infection-related ventilator-associated complications, 8 of possible VAP (PVAP), and 7 of conventional VAP (3.6, 1.8, 2.1, and 1.8/1000 ventilator days, respectively) were included in this study. Compared with non-VAE and non-VAP cases, PVAP and VAP cases had significantly increased mechanical ventilator days and ICU length of stay. Hospital and ICU mortalities were also significantly high in PVAP cases. Four out of seven VAP cases were consistent with PVAP, and the main reason for this discordance was that the deterioration of oxygenation did not meet the VAE criteria. Although VAE surveillance has lower sensitivity to cases using conventional VAP identification, it may be more useful in terms of prognostic prediction in Japan.
