For each summarised MEWS value the appropriate actions to be taken are found at the right. Regardless of the prior MEWS recorded, a sudden change in MEWS of 3 or more triggers activation of MET.

Figure 3.
The proportion of patients who were observed and managed according to WOC guidelines. Each data point shows WOC compliance measured on a day of the week. Compliance is defined as the proportion of patients who had all elements of the measure completed. The dashed lines are control limits showing the range of common cause variation. The figure shows only common cause variation, i.e. there is no sign of compliance on any day of the week deviating significantly from the average.
Figure 4.
MEWS compliance by MEWS element.
Compliance defined as the proportion of patients who had MEWS single elements measured at least once during previous 24 hours according to WOC guidelines. rr = Respiratory Rate, sat = Oxygen Saturation, tp = Temperature, bp = Blood Pressure, hr = Heart Rate, gcs = Glasgow Coma Scale. The dashed lines are control limits showing the range of common cause variation. One data point, GCS, is outside the control limits indicating that compliance with GCS measurement is significantly lower than with other elements.
