We evaluated temporal variability of telephone calls to the medical emergency team (MET), as well as patient outcome.
All calls over a 48-month period between December 2005 and November 2009 were included. The time of telephone calls was noted, and occurrence throughout the day was studied. We compared the number of calls between 8:00 and 20:00 and between 20:00 and 8:00, using a Wilcoxon test. Patient's age, gender, reason for call, and outcome were entered into the ICU's database.
Reporting data might have less accuracy during nights. Nevertheless, despite difficulty of capturing such data, our series suggests that there is a temporal variability of medical emergency team calls. The fact that the majority of calls occurred between 8:00 and 20:00 may probably be a reflection of the level of supervision and the general amount of patient activity within the hospital during the day.
