A warning on early-warning scores!

It is clinically intuitive that physiological deterioration precedes critical illness, and there is growing research evidence to support this belief.1–6 The use of track and trigger early-warning systems to facilitate the early recognition of the acutely deteriorating patient outside the critical care area of a hospital is based on this premise. The first such scoring system, based on a single parameter trigger, was developed in Liverpool, Australia as part of the Medical Emergency Team (MET) concept.7 This was followed by the development of a range of similar systems that have entered clinical practice around the world.89 These incorporate a variety of physiological variables in scoring, and trigger algorithms that are often more complex than the original MET's calling criteria. They use a wide range of weightings and cut-off points to develop . . . [Full Text of this Article]
