Kenward G, Castle N, Hodgetts T, Shaikh L. Evaluation of a medical emergency team one year after implementation. Resuscitation. 2004;61(3):257-263.Multiple physiological abnormalities are associated with increased mortality. Initiating “do not attempt resuscitation” (DNAR) decisions is a key part of MET activity. A reduction in cardiac arrest rate and overall mortality was noted but was not statistically significant. New systems need time to develop (“bed in”) and further research is needed to observe significant reductions in cardiac arrests and overall mortality.
