Aim To determine the value of the Modified Early Warning Score (MEWS) for general ward patients and its potential use as an alarm tool for ward nurses. Methods A combined prospective‐retrospective observational study was conducted with 153 patients in a university hospital (2013‐2014). All patients were admitted to the intensive care unit (ICU) from general wards. Parameters retrospectively studied were 5 MEWS values at 4 hourly intervals, up to 20 hours before ICU admission. Parameters prospectively studied were ICU length of stay, ICU mortality, and mortality after ICU discharge. Results Most frequent severe adverse events were acute respiratory failure (39.9%) and septic shock (20.3%). Modified Early Warning Score increased gradually during the last 20 hours, and most patients remained in the wards, above a cut‐off point ≥7 recorded at 4 hours before admission. Significant associations between latest MEWS score and ICU mortality and ICU length of stay were found. MEWS score≥ 7 hours before admission was highly associated with increased ICU and hospital mortality. Conclusion Patient deterioration in general wards can result in severe adverse events. Modified Early Warning Score is a strong predictor of outcome and may be used as a monitoring tool for potentially avoidable deaths and unplanned admissions to ICU.
