Expanded MEWS is more predictive.
Researchers studying the modified early warning score (MEWS) found several areas of weakness that led them to modify the tool, which is used to assess risk levels in ED patients. Their recommended modifications took into account a number of variables they thought would provide a more accurate prediction, and their research seems to confirm their approach. Those variables include: whether the patient was brought to the ED via ambulance; patients who received intravenous antibiotics in the ED or who had infectious illness; the patient's length of stay.
