A Trend-Based Early Warning Score Can Be Implemented in a Hospital Electronic Medical Record to Effectively Predict Inpatient Deterioration

  Figure 1.. The receiver operating characteristic curve comparing the logistic model to the Modified Early Warning Score (MEWS) and National Early Warning Score (NEWS) scores in the 48 hr prior to an adverse event. Simulations were run on a holdout sample of 86,989 patients. AUC = area under the curve.
