Collected were: demographic, physiological, and clinical variables; main diagnosis; and data on early mortality. The main outcome variable was mortality from any cause within 48 hours.<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X19005041_as4\"><jats:title>Results:<\/jats:title><jats:p>From April 1, 2018 through February 28, 2019, a total of 1,288 patients were included in this study. Of these, 262 (20.3%) participants required assistance for trauma and injuries by external agents. Early mortality within the first 48 hours due to any cause affected 69 patients (5.4%). The system with the best predictive capacity was the NEWS2 with an area under the curve (AUC) of 0.891 (95% CI, 0.84-0.94); a sensitivity of 79.7% (95% CI, 68.8-87.5); and a specificity of 84.5% (95% CI, 82.4-86.4) for a cut-off point of nine points, with a positive likelihood ratio of 5.14 (95% CI, 4.31-6.14) and a negative predictive value of 98.7% (95% CI, 97.8-99.2).<\/jats:p><\/jats:sec><jats:sec id=\"S1049023X19005041_as5\"><jats:title>Conclusion:<\/jats:title><jats:p>Prehospital scores of the NEWS2 are easy to obtain and represent a reliable test, which make it an ideal system to help in the initial assessment of high-risk patients, and to determine their level of triage effectively and efficiently. The Prehospital Emergency Medical System (PhEMS) should evaluate the inclusion of the NEWS2 as a triage system, which is especially useful for the second triage (evacuation priority).<\/jats:p><\/jats:sec>","DOI":"10.1017\/s1049023x19005041","type":"journal-article","created":{"date-parts":[[2019,10,25]],"date-time":"2019-10-25T08:53:16Z","timestamp":1571993596000},"page":"610-618","source":"Crossref","is-referenced-by-count":39,"title":["Accuracy of National Early Warning Score 2 (NEWS2) in Prehospital Triage on In-Hospital Early Mortality: A Multi-Center Observational Prospective Cohort Study"],"prefix":"10.1017","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1773-2860","authenticated-orcid":false,"given":"Francisco","family":"Mart\u00edn-Rodr\u00edguez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ra\u00fal","family":"L\u00f3pez-Izquierdo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"del Pozo Vegas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan F.","family":"Delgado Benito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virginia","family":"Carbajosa Rodr\u00edguez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda N.","family":"Diego Rasilla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 Luis","family":"Mart\u00edn Conty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agust\u00edn","family":"Mayo Iscar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Santiago","family":"Otero de la Torre","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Violante","family":"M\u00e9ndez Mart\u00edn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel A.","family":"Castro Villamor","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2019,10,25]]},"reference":[{"key":"S1049023X19005041_ref45","doi-asserted-by":"publisher","DOI":"10.1136\/emermed-2017-207227"},{"key":"S1049023X19005041_ref44","doi-asserted-by":"publisher","DOI":"10.1155\/2015\/983409"},{"key":"S1049023X19005041_ref43","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2018.07.001"},{"key":"S1049023X19005041_ref40","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0000000000001516"},{"key":"S1049023X19005041_ref33","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0000000000001191"},{"key":"S1049023X19005041_ref32","doi-asserted-by":"publisher","DOI":"10.1161\/JAHA.117.007581"},{"key":"S1049023X19005041_ref30","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-016-1408-0"},{"key":"S1049023X19005041_ref27","doi-asserted-by":"publisher","DOI":"10.1136\/emermed-2016-206115"},{"key":"S1049023X19005041_ref26","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijnurstu.2017.09.003"},{"key":"S1049023X19005041_ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.resuscitation.2014.12.029"},{"key":"S1049023X19005041_ref19","volume-title":"National Early Warning Score (NEWS) 2: Standardizing the Assessment of Acute-Illness Severity in the NHS.
