The Modified Early Warning Score (MEWS) has been used in medical wards as a decision-making instrument. Here we show a pilot study on MEWS introduction as a routine method for care improvement in urgency/emergency surgical patients.
Patients enrolled underwent urgent/emergency surgery due to trauma, appendicitis, cholecystitis, gut perforation or ischemia. Data collection with MEWS involved patients admitted for between April and October 2009. It was measured during preoperative evaluation and within 24 hours after surgery. To evaluate the role of MEWS utilization we use as outcome criteria: hospital length of stay (LOS), mortality, ICU or subintensive care unit (SCU) need. The MEWS group was compared with a control historical group (January 2008 to March 2009).
Age, years (mean)
Hospital LOS, days (mean)
Mortality, % (n)
ICU admission, % (n)
SCU admission, % (n)
These preliminary results indicate that MEWS, used in preoperative evaluation and follow-up in urgent/emergency surgical patients, can have an important impact on patient care and mortality.
