Rapid response systems

In reply: Many thanks to Buist for his comments. He is quite correct in pointing out that we used the wrong reference.1 The correct reference was another study showing that the mortality of patients subject to a rapid response system (RRS) was higher than that for patients in an intensive care unit.2 Our apologies for this error.
In relation to the criticality of RRS calls, the largest trial on RRSs showed that of over 2000 calls, only five did not require critical care interventions.3 Moreover, the greater the number of calls, the greater the reduction in deaths and cardiac arrests.4
The high number of potentially preventable deaths and cardiac arrests when the admitting team cared for seriously ill patients on the general wards was the reason why RRS teams are now operating in most Australian hospitals.
Finally, in our opinion, the reference used to demonstrate overdependence on the system5 does not, in fact, show overdependence but, instead, a strong association of a reduction in deaths and cardiac arrests with the gradual uptake of RRSs in New South Wales hospitals.
