"…as the physicians say it happens in hectic fever, that in the beginning of the malady it is easy to cure but difficult to detect, but in the course of time, not having been either detected or treated in the beginning, it becomes easy to detect but difficult to cure."
The Prince Niccolò Machiavelli

RRS Outcomes
• Mortality
• Acute life-threatening events
– Cardiac arrest, respiratory arrest & other ALTEs
• Serious Adverse events
• Avoidable Harm
– Predictable
– Preventable
• Failure to rescue
Critical deterioration = ICU transfer & within 12 hours Non-invasive ventilation or Intubation or Vasopressor infusion

RRS Outcomes Conclusions: Chapman ICM 2009
Evidence supporting validity, reliability & utility of paediatric alert criteria is weak
Studies are needed to determine which physiological parameters should be included
Conclusions: Chan Arch Intern Med 2010
In children, RRT was associated with 37.7% reduction in rates of cardiopulmonary arrest and 21.4% reduction in hospital mortality rates
….studies frequently found evidence that reduction in cardiopulmonary arrest were prevented out of proportion to deaths, raising questions about mechanisms of improvement

Early Warning Systems
There's no use trying to change human nature
It's been the same for a very long time
Instead, go after the tools
New tools make new practices
Better tools make better practices
