CPR Quality Officer role to improve CPR quality: A multi-centred international simulation randomised control trial.

Background: An out-of-hospital cardiac arrest requires early recognition, prompt and quality clinical interventions, and coordination between different clinicians to improve outcomes. Clinical team leaders and clinical teams have high levels of cognitive burden. We aimed to investigate the effect of a dedicated Cardio-Pulmonary Resuscitation (CPR) Quality Officer role on team performance. Methods: This multi-centre randomised control trial used simulation in universities from the UK, Poland, and Norway. Student Paramedics participated in out-of-hospital cardiac arrest scenarios before randomisation to either traditional roles or assigning one member as the CPR Quality Officer. The quality of CPR was measured using QCPR® and Advanced Life Support (ALS) elements were evaluated. Results: In total, 36 teams (108 individuals) participated. CPR quality from the first attempt (72.45%, 95% confidence interval [CI] 64.94 to 79.97) significantly increased after addition of the CPR Quality role (81.14%, 95% CI 74.20 to 88.07, p = 0.045). Improvement was not seen in the control group. The time to first defibrillation had no significant difference in the intervention group between the first attempt (53.77, 95% CI 36.57-70.98) and the second attempt (48.68, 95% CI 31.31-66.05, p = 0.84). The time to manage an obstructive airway in the intervention group showed significant difference (p = 0.006) in the first attempt (168.95, 95% CI 110.54-227.37) compared with the second attempt (136.95, 95% CI 87.03-186.88, p = 0.1). Conclusion: A dedicated CPR Quality Officer in simulated scenarios improved the quality of CPR compressions without a negative impact on time to first defibrillation, managing the airway, or adherence to local ALS protocols.

Management of gestational supraventricular tachycardia with a 'modified' modified Valsalva manoeuvre.

A 36 year old woman with chest pain and palpitations at 34 weeks gestation (gravidity 2, parity 1) presented to the emergency department where she was found to be in supraventricular tachycardia (SVT). This patient had an earlier episode of SVT during the same pregnancy that was managed with intravenous adenosine. During both presentations a REVERT trial style 'modified' Valsalva manoeuvre (including supine positioning with passive leg raise) was attempted without success. Acknowledging the potential for vena caval compression in pregnant patients while in the Trendelenburg position, the same manoeuvre was attempted with the novel additional of 45 degree left pelvic tilt. This 'modified' modified Valsalva was successful in restoring sinus rhythm, suggesting this technique may warrant further investigation as a viable treatment for pregnant patients with hemodynamically stable SVT.

Perspectives of emergency department clinicians on the challenges of addressing low back pain in the emergency setting: A qualitative study.

OBJECTIVE: To identify and explore ED clinician perspectives on: (i) why patients with low back pain (LBP) present to the ED and are admitted into hospital from ED; (ii) barriers and enablers they face when providing care to patients with LBP; and (iii) strategies to improve the care of patients with LBP, and associated care processes, in the ED. METHODS: We undertook a qualitative exploratory study with ED clinicians (medical officers, nurses and physiotherapists) at a tertiary-level public hospital in New South Wales, Australia, using focus groups and individual interviews. We used thematic analysis to synthesise participant responses to answer the predefined research questions. RESULTS: Twenty-one clinicians participated (two individual interviews, 19 focus groups). Perceptions about better access to the ED and advanced care within ED were thought to drive presentations to the ED for LBP. Barriers and enablers to optimal patient care included patient-, clinician- and service-level factors. The main strategies to improve care included a department LBP pathway, modernised patient and clinician resources, better follow-up options post-discharge and improved communication between ED and primary care. CONCLUSION: We identified a range of targets to improve LBP management in ED. Clinicians perceived internal and external factors to the ED as influences of ED presentation and hospital admission. Clinicians also reported that patient-, clinician- and service-level barriers and enablers influenced patient management in ED. Strategies suggested by clinicians included improved follow-up options, access to resources and an 'LBP pathway' to support decision making.

Factors associated with paediatric and adolescent Emergency Department presentations involving acute behavioural disturbance events.

AIM: Studies reporting factors associated with paediatric/adolescent acute behavioural disturbance (ABD) in the Emergency Department (ED) are lacking. The aim of this study is to describe paediatric/adolescent ED presentations involving ABD events. METHODS: A retrospective chart review of presentations involving ABD events, identified via hospital security log, to a tertiary referral paediatric ED during the 2017 calendar year. Data reported included: cause of presentation, use of sedation/physical restraint, ED/inpatient length of stay (LOS) and time requiring security staff presence. RESULTS: From 280 reported ABD episodes 26 were excluded leaving 254 events involving 150 patients across 233 presentations of whom 38 (25.3%) presented on multiple occasions. Median age was 14 years (interquartile range (IQR): 13-16), 132/233 (56.7%) were female, 167/233 (71.7%) primary mental health complaints, 30/233 (12.9%) deliberate self-harm, 18/233 (7.7%) deliberate self-poisoning, 11/233 (4.7%) acute intoxication and 7/233 (3.0%) other. Transport to hospital involved police and ambulance in 124/233 (53.2%), ambulance only 71/233 (30.5%), police only 16/233 (6.9%), relative or carer 20/233 (8.6%), with self-presentation in 2/233 (0.9%). Sedation or physical restraint was used in 81/233 (34.8%), both 38/233 (16.3%), restraint only 26/233 (11.2%) and sedation only 17/234 (7.3%). Intra-muscular droperidol accounted for 57/96 (59.4%) sedations, IM/IV benzodiazepines 15/96 (15.6%), IM/IV ketamine 5/96 (5.2%) and 19/96 (19.8%) other. Discharge from ED occurred in 171/233 (73.1%) with median ED LOS 5.1 h (IQR: 3.5-7.7) and median hospital LOS 92.4 h (IQR: 47.5-273.4) for those admitted. The Mental Health Act was utilised in 183/233 (78.5%) presentations. Median security staff time requirement per presentation was 2.4 h (IQR: 1.0-3.9). CONCLUSIONS: Paediatric/adolescent ED presentations involving ABD are primarily due to mental health complaints. Less than half require the use of sedation/physical restraint. Time requiring security staff involvement is a significant resource consumption.

Cardiac Arrest Nurse Leadership (CANLEAD) trial: a simulation-based randomised controlled trial implementation of a new cardiac arrest role to facilitate cognitive offload for medical team leaders.

BACKGROUND: Medical team leaders in cardiac arrest teams are routinely subjected to disproportionately high levels of cognitive burden. This simulation-based study explored whether the introduction of a dedicated 'nursing team leader' is an effective way of cognitively offloading medical team leaders of cardiac arrest teams. It was hypothesised that reduced cognitive load may allow medical team leaders to focus on high-level tasks resulting in improved team performance. METHODS: This randomised controlled trial used a series of in situ simulations performed in two Australian emergency departments in 2018-2019. Teams balanced on experience were randomised to either control (traditional roles) or intervention (designated nursing team leader) groups. No crossover between groups occurred with each participant taking part in a single simulation. Debriefing data were collected for thematic analysis and quantitative evaluation of self-reported cognitive load and task efficiency was evaluated using the NASA Task Load Index (NTLX) and a 'task time checklist' which was developed for this trial. RESULTS: Twenty adult cardiac arrest simulations (120 participants) were evaluated. Intervention group medical team leaders had significantly lower NTLX scores (238.4, 95% CI 192.0 to 284.7) than those in control groups (306.3, 95% CI 254.9 to 357.6; p=0.02). Intervention group medical team leaders working alongside a designated nursing leader role had significantly lower cognitive loads than their control group counterparts (206.4 vs 270.5, p=0.02). Teams with a designated nurse leader role had improved time to defibrillator application (23.5 s vs 59 s, p=0.004), faster correction of ineffective compressions (7.5 s vs 14 s, p=0.04), improved compression fraction (91.3 vs 89.9, p=0.048), and shorter time to address reversible causes (107.1 s vs 209.5 s, p=0.002). CONCLUSION: Dedicated nursing team leadership in simulation based cardiac arrest teams resulted in cognitive offload for medical leaders and improved team performance.

The Acute Incident Response Program: A Framework Guiding Multidisciplinary Responses to Acutely Traumatic or Stress-Inducing Incidents in the ED Setting.

BACKGROUND: Clinicians working in the ED setting are exposed to traumatic and stress-inducing incidents, which may increase the incidence of psychological sequelae, including burnout and acute stress disorders. The purpose of this project was to develop and implement a novel debriefing program as an early intervention for acutely stress-inducing events in the emergency department. METHODS: The 2-stage Acute Incident Response program was developed and implemented in the emergency department of the John Hunter Hospital to guide an interprofessional response to acutely stress-inducing incidents. This psychological support framework draws on existing concepts of critical incident stress management along with elements of contemporary "hot debriefing" models to create a concise, clinician-led response program incorporating elements of both work group peer support and clinical team performance improvement. The Acute Incident Response program is novel in its concurrent focus on both salient clinical factors and emotional responses of affected clinicians. RESULTS: The developed Acute Incident Response program framework predominantly focuses on the wide dissemination of a peer-driven debriefing model. When additional support is deemed necessary by trained clinical champions after the Hot Acute Incident Response process, escalation to a central response coordinator ensures targeted secondary support follow-up for all affected team members. This program has been introduced at 1 site and warrants further targeted investigation to determine its efficacy and utility in a broad range of clinical contexts. CONCLUSION: The Acute Incident Response program is an accessible and meaningful model to guide a functional, clinician-led response to acute incidents in the ED setting. The model could feasibly be applied in a wide variety of clinical contexts.

Laughter is the best medicine: A novel finding in the treatment of supraventricular tachycardia in a paediatric emergency patient.

We present a novel case of laughter induction that was noted to terminate an episode of supraventricular tachycardia (SVT) in a 10 year old girl who presented to a large metropolitan emergency department. In the initial management of this patient's SVT, traditional vagal maneuvers (including the valsalva maneuver and stimulation of the mammalian divers reflex) were attempted unsuccessfully. While awaiting further treatment, nursing staff presented the patient with an inflated examination glove that had been crafted into the shape of an elephant. This resulted in a fit of laughter that appeared to terminate the child's arrhythmia. Existing studies identified in the literature help to establish a correlation between the thoracic and cardiovascular physiology of laughter and the mechanics of the traditional Valsalva maneuver. Our patient's case highlights the potential positive impact of this physiology when applied in the context of the paediatric patient presenting in SVT. In the context of the available evidence, the case of our 10-year-old patient serves as a thought-provoking example of the real world relationship between laughter and the traditional Valsalva maneuver. The utility of laughter in the management of supraventricular tachycardia is an area that warrants further investigation.
