To the Editor: Since 2008, the Australian Capital Territory’s public acute health care system has successfully been using multiple-parameter and single-parameter track, trigger and response (TTR) systems in parallel for the recognition of and response to clinical deterioration in patients. Jenkins and colleagues correctly identify that there is a general lack of agreement on the use of TTR systems around Australia, although they note that the most commonly used rapid response system is the medical emergency team (MET) alert which is triggered by a single parameter, a vital sign derangement, or a concern for the patient.1 As Jenkins et al suggest, a multiple-parameter TTR system may trigger a response earlier than might occur with MET parameters.
