How does it work?

• The EWET score relies on observation parameters that suggest deviation from normal levels.

• Small changes in individual observations may predict deterioration in the seriously unwell patient before obvious, and often too late, critical changes in condition occur.

• It does not predict patient outcome.

Calculation

• In order to calculate the EWET Score it is necessary to perform a series of observations.

• The EWET score does not require any additional training or equipment in order for first aiders/responders to generate a physiological score.

These are as follows:

Scoring Matrix

Outcome

The total score of the three component parts is one method of deciding whether or no further clinical support, advice or assistance is needed

What does this actually mean in practice?

Does EWET apply in this case?

No probably not, if you had concerns about the patient, you were no likely to make a brief assessment, offer medication and allow the patient to continue with their activity.

Basic patient observations in this case are unlikely to be useful or taken

Does EWET apply in this case?

Yes, the patient is obviously unwell and you need to monitor them for signs of improvement or further deterioration

Basic patient observations will be undertaken in this situation, don't forget you can ask for further clinical support before EWET if you have concerns about the patient
