Background: The National Early Warning Score (NEWS) is an assessment scale of in-hospital patients’ conditions. The purpose of this study was to assess the appropriateness of a potential off-label use of NEWS by the emergency medical system (EMS) to facilitate the identification of critical patients and to trigger appropriate care in the pre-hospital setting. Methods: A single centre, longitudinal, prospective study was carried out between July and August 2020 in the EMS service of Bologna. Home patients with age ≥ 18 years old were included in the study. The exclusion criterion was the impossibility to collect all the parameters needed to measure NEWS. Results: A total of 654 patients were enrolled in the study. The recorded NEWS values increased along with the severity of dispatch priority code, the EMS return code, the emergency department triage code, and with patients’ age (r = 0.135; p = 0.001). The aggregated value of NEWS was associated with an increased risk of hospitalization (OR = 1.30 (1.17; 1.34); p < 0.0001). Conclusion: This study showed that the use of NEWS in the urgent and emergency care services can help patient assessment while not affecting EMS crew operation and might assist decision making in terms of severity-code assignment and resources utilization.

Background. The quality of cardiopulmonary resuscitation (CPR) is pivotal in improving the outcome of cardiac arrest. Nevertheless, there is evidence that even professional rescuers may deliver ineffective chest compressions (CCs). We sought to evaluate the impact of a CPR feedback device on the quality of CC performed by a supposedly highly trained and skilled population of attendees to the national annual congress of the Italian Resuscitation Council. Methods. A total of 202 congress attendees were enrolled to perform 2 min CC without feedback, followed by a 5 min rest and another 2 min interval of CC with feedback. Moreover, participants were randomly assigned to two study groups: “feedback later”, in which the first 2 min CCs were delivered without the feedback, and “feedback first”, in which the first 2 min CCs were aided by feedback. CPR quality has been analyzed in terms of the percentage of CC with adequate depth (CC, %), complete chest release (CR, %), and the CC rate (CC/min). Results. Approximately 60% of correct CCs were performed without feedback, which significantly increased to 79% with the use of feedback. In the “feedback later” group, the percentage of correctly performed CC and CR significantly increased during the second 2 min interval of CC with feedback (median value 51% vs. 86%, p < 0.0001 and 71% vs. 84%, p = 0.025, respectively). In the “feedback first” group, the percentage of correct CC remained stable during the two CC intervals (71% vs. 80%, p = 0.06), while CR was better without the help of the feedback (70% vs. 93%, p < 0.0001). CC/min was in the recommended range (100–120/min) in all the CC events. Conclusions. In this population of expected highly skilled CPR providers, the overall quality was inconsistent and, in many cases, did not reach guidelines recommendations. The use of a feedback device significantly improved the quality of CC. When the feedback device was used in the first CC attempt, it had a learning effect that was reflected in maintaining quality during the second CC series.
