Rapid response teams—walk, don't run.

Rapid response teams (RRTs) have been widely advocated as a means of averting adverse clinical outcomes for inpatients, by intervening and treating patients before they become critically ill. However, this commentary finds that the published evidence concerning RRTs is generally of poor methodological quality and does not conclusively demonstrate any benefits for patients. The authors conclude that RRTs are a potentially useful intervention but not one worthy of wider implementation until more definitive evidence is available.
