Abstract
INTRODUCTION The National Early Warning Score-2 (NEWS-2) is used to detect deteriorating patients in hospital settings. We aimed to understand how NEWS-2 functions in the real-life setting of an acute respiratory unit. METHODS Clinical observations data were extracted for adult patients (age ≥18 years), admitted under the care of respiratory medicine services from July to December 2019, who had at least one recorded task relating to clinical deterioration. The timing and nature of urgent out-of-hours medical reviews (escalations) were extracted through manual review of the case notes. RESULTS The data set comprised 765 admission episodes (48.9% women) with a mean (SD) age of 69.3 (14.8). 8971 out of 35 991 out-of-hours observation sets (24.9%) had a NEWS-2 ≥5, and 586 of these (6.5%) led to an escalation. Out of 687 escalations, 101 (14.7%) were associated with observation sets with NEWS-2<5. Rising oxygen requirement and extreme values of individual observations were associated with an increased risk of escalation. 57.6% of escalations resulted in a change in treatment. Inpatient mortality was higher in patients who were escalated at least once, compared with those who were not escalated. CONCLUSIONS Most observation sets with NEWS-2 scores ≥5 did not lead to a medical escalation in an acute respiratory setting out-of-hours, but more than half of escalations resulted in a change in treatment. Rising oxygen requirement is a key indicator of respiratory patient acuity which appears to influence the decision to request urgent out-of-hours medical reviews.

Abstract
Mechanical ventilation weaning within intensive care units (ICU) is a difficult process, while crucial when considering its impact on morbidity and mortality. Failed extubation and prolonged mechanical ventilation both carry a significant risk of adverse events. We aimed to determine predictive factors of extubation success using data-mining and artificial intelligence. A prospective physiological and biomedical signal data warehousing project. A 21-beds medical Intensive Care Unit of a University Hospital. Adult patients undergoing weaning from mechanical ventilation. Hemodynamic and respiratory parameters of mechanically ventilated patients were prospectively collected and combined with clinical outcome data. One hundred and eight patients were included, for 135 spontaneous breathing trials (SBT) allowing to identify physiological parameters either measured before or during the trial and considered as predictive for extubation success. The Early-Warning Score Oxygen (EWSO2) enables to discriminate patients deemed to succeed extubation, at 72-h and 7-days. Cut-off values for EWSO2 (AUC = 0.80; Se = 0.75; Sp = 0.76), mean arterial pressure and heart-rate variability parameters were determined. A predictive model for extubation success was established including body-mass index (BMI) on inclusion, occlusion pressure at 0,1 s. (P0.1) and heart-rate analysis parameters (LF/HF) both measured before SBT, and heart rate during SBT (global performance 62%; 83%). The data-mining process enabled to detect independent predictive factors for extubation success and to develop a dynamic predictive model using artificial intelligence. Such predictive tools may help clinicians to better discriminate patients deemed to succeed extubation and thus improve clinical performance.

Abstract
This review critiques the benefits and drawbacks of the United Kingdom's National Early Warning Score (NEWS). Potential developments for the future are considered, as well as the role for NEWS in an emergency department (ED). The ability of NEWS to predict death within 24 h has been well validated in multiple clinical settings. It provides a common language for the assessment of clinical severity and can be used to trigger clinical interventions. However, it should not be used as the only metric for risk stratification as its ability to predict mortality beyond 24 h is not reliable and greatly influenced by other factors. The main drawbacks of NEWS are that measuring it requires trained professionals, it is time consuming and prone to calculation error. NEWS is recommended for use in acute UK hospitals, where it is linked to an escalation policy that reflects postgraduate experience; patients with lower NEWS are first assessed by a junior clinician and those with higher scores by more senior staff. This policy was based on expert opinion that did not consider workload implications. Nevertheless, its implementation has been shown to improve the efficient recording of vital signs. How and who should respond to different NEWS levels is uncertain and may vary according to the clinical setting and resources available. In the ED, simple triage scores which are quicker and easier to use may be more appropriate determinants of acuity. However, any alternative to NEWS should be easier and cheaper to use and provide evidence of outcome improvement.

Abstract
Quantitatively assessing personal health status is gaining increasing attention due to the improvement of diagnostic technology and the increasing occurrence of chronic pathologies. Monitoring physiological parameters allows for retrieving a general overview of the personal health status. Respiratory activity can provide relevant information, especially when pathologies affect the muscles and organs involved in breathing. Among many technologies, wearables may represent a valid solution for continuous and remote monitoring of respiratory activity, thus reducing healthcare costs. The most popular wearables used in this arena are based on detecting the breathing-induced movement of the chest wall. Therefore, their use in patients with impaired chest wall motion and abnormal respiratory kinematics can be challenging, but literature is still in its infancy. This study investigates the performance of a custom wearable device for respiratory monitoring in post-stroke patients. We tested the device on six hemiplegic patients under different respiratory regimes. The estimated respiratory parameters (i.e., respiratory frequency and the timing of the respiratory phase) demonstrated good agreement with the ones provided by a gold standard device. The promising results of this pilot study encourage the exploitation of wearables on these patients that may strongly impact the treatment of chronic diseases, such as hemiplegia.

Abstract
AIM/OBJECTIVE The aim is to examine and map the respiratory skills taught in the pre-registration nursing curriculum (2010). BACKGROUND Respiratory assessment and care are fundamental clinical skills enabling nurses to treat and care for people with acute and chronic respiratory diseases. The incidence of respiratory disease is rising, globally and most nurses will care for respiratory patients during their career. The extent of pre-registration respiratory specific education delivered in UK NMC (Nursing and Midwifery Council) approved education institutions (AEIs) is currently unknown. The move to the 2018 revised NMC standards for pre-registration nursing offers AEIs the opportunity to review provision of respiratory education. This study describes respiratory education delivered to pre-registration nurses in UK AEIs prior to implementation of the new NMC standards. Curriculum re-design can be adapted for the global nursing community. DESIGN This is a freedom of information survey; to gather, examine and map curriculum content. METHODS A survey of UK AEIs was conducted to initially scope provision of respiratory education for pre-registration nursing programmes. AEIs were emailed a freedom of information (FOI) request and provided information about the curriculum between April-June 2019. RESULTS Seventy-five UK AEIs providing pre-registration nursing programmes responded. Over half of AEIs dedicated over 4 h of teaching respiratory anatomy and physiology (60.8%), respiratory pathophysiology (75.3%) and long- term respiratory conditions (60.3%). Less than half (44.4%) spent over 4 h teaching respiratory health and prevention of respiratory disease. Just over a third spent over 4 h on respiratory pharmacology (33.8%), local and national respiratory guidelines (33.3%) and information on pulmonary rehabilitation and other interventions for the management of respiratory conditions (35.2%). In most AEIs, skills laboratories were used to teach respiratory skills. Student competence was not always assessed. Respiratory learning was reported to take place during practice placements, but this was variable. CONCLUSIONS Variation exists in provision of respiratory education in pre-registration nursing programmes across the UK. Whilst some respiratory topics appear to be covered adequately, others have limited time on knowledge and skills teaching. New standards and curricula offer AEIs the opportunity to enhance this provision. Adaptations can be made and the curriculum transferred to the global nursing workforce. TWEETABLE ABSTRACT Gaps have been identified in respiratory teaching pre-registration nurse education. Curriculum redesign to focus on respiratory care.

Abstract
BACKGROUND Emergency medical care for critically ill nontrauma patients (CINT) varies between different emergency departments (ED) and healthcare systems, while resuscitation of trauma patients is always performed within the ED. In many ED CINT are treated and stabilized while in many German smaller hospitals CINT are transferred directly to the intensive care unit (ICU) without performing critical care measures in the ED. Little is known about the resuscitation room management of CINT regarding patient characteristics and outcome although bigger hospitals perform ED resuscitation of CINT in routine care. Against this background we conducted this retrospective analysis of CINT treated by an ED resuscitation room concept in a German 756 bed teaching hospital. METHODS The collective of CINT treated within the ED resuscitation room (1 October 2018 to 31 March 2019) was analyzed after ethical approval. After each resuscitation room operation, the team leader filled out a standardized paper-based questionnaire and qualified the patient as a resuscitation room patient this way. Only patients who underwent invasive procedures and were admitted to ICU or died in the ED were included. Patient characteristics, performed critical care measures, short-term outcomes and the comparison of admission characteristics between survivors and non-survivors were evaluated. Additionally, the accordance of ED admission diagnoses and discharge diagnoses were analyzed. RESULTS Overall, 243 of 19,854 ED patients (1.22%) were treated in the resuscitation room. After exclusion of trauma patients, 193 (0.97%) CINT were included. Overall mortality was 29% (n = 56), 24‑h mortality was 13% (n = 25). Patient characteristics (vital signs, blood gas analysis) differed significantly between survivors and nonsurvivors except for respiratory rate and pain scale. An excerpt of conducted resuscitation room measures was as follows: arterial line n = 78 (40%); noninvasive ventilation n = 60 (31%); endotracheal intubation n = 56 (29%); cardiopulmonary resuscitation n = 19 (10%), central venous line n = 8 (4%). The number of conducted measures differed between survivors and nonsurvivors (median and interquartile range, IQR): 4 (IQR 2) vs. 4 (IQR 3) p = 0.0453. The length of ED stay was 148.2 ± 202.7 min until the patient was admitted to an ICU or died within the ED. ED admission diagnoses matched with hospital discharge diagnoses in 78%. CONCLUSION The observed mortality was high and was comparable to patient collectives with septic shock. Nonsurvivors showed significantly more impaired vital parameters and blood gas analysis parameters. Vital parameters together with blood gas analysis might enable ED risk stratification of CINT. Resuscitation room management enables immediate stabilization and diagnostic work-up of CINT even when no ICU bed is available. Furthermore, optimal allocation to specialized ICUs can probably be enabled more accurately after a first diagnostic work-up; however, although a first diagnostic work-up including laboratory tests and computed tomography in many cases was performed, ED admission and hospital discharge diagnoses matched only in 78%.

Abstract
Respiratory rate is a fundamental vital sign that is sensitive to different pathological conditions (e.g., adverse cardiac events, pneumonia, and clinical deterioration) and stressors, including emotional stress, cognitive load, heat, cold, physical effort, and exercise-induced fatigue. The sensitivity of respiratory rate to these conditions is superior compared to that of most of the other vital signs, and the abundance of suitable technological solutions measuring respiratory rate has important implications for healthcare, occupational settings, and sport. However, respiratory rate is still too often not routinely monitored in these fields of use. This review presents a multidisciplinary approach to respiratory monitoring, with the aim to improve the development and efficacy of respiratory monitoring services. We have identified thirteen monitoring goals where the use of the respiratory rate is invaluable, and for each of them we have described suitable sensors and techniques to monitor respiratory rate in specific measurement scenarios. We have also provided a physiological rationale corroborating the importance of respiratory rate monitoring and an original multidisciplinary framework for the development of respiratory monitoring services. This review is expected to advance the field of respiratory monitoring and favor synergies between different disciplines to accomplish this goal.
