Description
Summary:•EMS must attend complex patients, with few diagnostic means and in a quick way.•EWS can help to know the presence of SAEs and their short-term prognosis.•The use of NEWS2 by Nurses in the prehospital setting can help decision making.•Use of NEWS2 improves communication between professionals of different care levels.•Early detection of SAEs results in better attention to time-dependent pathologies. The National Early Warning Score 2 (NEWS2) scores can help identify clinical deterioration. To assess the predictive capacity of the NEWS2 at prehospital level for the detection of early mortality in the hospital. Prospective multicenter cohort study, in which we compiled a database of observed vital signs between March 1, 2018 and May 30, 2019. We collected demographic data, vital signs (respiration rate, oxygen saturation, supplemental oxygen, temperature, systolic blood pressure, heart rate and level of consciousness), prehospital diagnosis and hospital mortality data. We calculated the AUROC of the NEWS2 for early mortality. We included a total of 2335 participants. Median age was 69 years (IQR 54–81 years). The AUC for mortality within one day was 0.862 (95%CI:0.78–0.93), within two days 0.885 (95%CI:0.84–0.92) and within seven days 0.835 (95%CI:0.79–0.87) (in all cases, p
