The CPES card has recently been further revised so it now contains the Modified Early Warning Score (MEWS) Module. The MEWS is a simple guide used by hospital nursing & medical staff as well as emergency medical services such as ambulance services, to quickly determine the degree of illness of a patient.
It is based on data derived from four physiological readings (systolic blood pressure, heart rate, respiratory rate, body temperature) and one observation (level of consciousness, AVPU). The resulting observations are compared to a normal range to generate a single composite score.
The new MEWS Module allows for 12 readings to be taken and recorded. Each of the readings and the observation is given a number, ranging from 0 (normal range) to 1, 2 or 3, depending on the variance from the normal range.
This will make the system more sensitive to patients will illness rather than trauma. All the cards after this date will have the MEWS Module inside
