Management of adult cardiac arrest in the COVID-19 era: consensus statement from the Australasian College for Emergency Medicine.

INTRODUCTION: The global pandemic of coronavirus disease 2019 (COVID-19) has caused significant worldwide disruption. Although Australia and New Zealand have not been affected as much as some other countries, resuscitation may still pose a risk to health care workers and necessitates a change to our traditional approach. This consensus statement for adult cardiac arrest in the setting of COVID-19 has been produced by the Australasian College for Emergency Medicine (ACEM) and aligns with national and international recommendations. MAIN RECOMMENDATIONS: In a setting of low community transmission, most cardiac arrests are not due to COVID-19. Early defibrillation saves lives and is not considered an aerosol generating procedure. Compression-only cardiopulmonary resuscitation is thought to be a low risk procedure and can be safely initiated with the patient's mouth and nose covered. All other resuscitative procedures are considered aerosol generating and require the use of airborne personal protective equipment (PPE). It is important to balance the appropriateness of resuscitation against the risk of infection. Methods to reduce nosocomial transmission of COVID-19 include a physical barrier such as a towel or mask over the patient's mouth and nose, appropriate use of PPE, minimising the staff involved in resuscitation, and use of mechanical chest compression devices when available. If COVID-19 significantly affects hospital resource availability, the ethics of resource allocation must be considered. CHANGES IN MANAGEMENT: The changes outlined in this document require a significant adaptation for many doctors, nurses and paramedics. It is critically important that all health care workers have regular PPE and advanced life support training, are able to access in situ simulation sessions, and receive extensive debriefing after actual resuscitations. This will ensure safe, timely and effective management of the patients with cardiac arrest in the COVID-19 era.

ICare-ACS (Improving Care Processes for Patients With Suspected Acute Coronary Syndrome): A Study of Cross-System Implementation of a National Clinical Pathway.

BACKGROUND: Efforts to safely reduce length of stay for emergency department patients with symptoms suggestive of acute coronary syndrome (ACS) have had mixed success. Few system-wide efforts affecting multiple hospital emergency departments have ever been evaluated. We evaluated the effectiveness of a nationwide implementation of clinical pathways for potential ACS in disparate hospitals. METHODS: This was a multicenter pragmatic stepped-wedge before-and-after trial in 7 New Zealand acute care hospitals with 31 332 patients investigated for suspected ACS with serial troponin measurements. The implementation was a clinical pathway for the assessment of patients with suspected ACS that included a clinical pathway document in paper or electronic format, structured risk stratification, specified time points for electrocardiographic and serial troponin testing within 3 hours of arrival, and directions for combining risk stratification and electrocardiographic and troponin testing in an accelerated diagnostic protocol. Implementation was monitored for >4 months and compared with usual care over the preceding 6 months. The main outcome measure was the odds of discharge within 6 hours of presentation RESULTS: There were 11 529 participants in the preimplementation phase (range, 284-3465) and 19 803 in the postimplementation phase (range, 395-5039). Overall, the mean 6-hour discharge rate increased from 8.3% (range, 2.7%-37.7%) to 18.4% (6.8%-43.8%). The odds of being discharged within 6 hours increased after clinical pathway implementation. The odds ratio was 2.4 (95% confidence interval, 2.3-2.6). In patients without ACS, the median length of hospital stays decreased by 2.9 hours (95% confidence interval, 2.4-3.4). For patients discharged within 6 hours, there was no change in 30-day major adverse cardiac event rates (0.52% versus 0.44%; P=0.96). In these patients, no adverse event occurred when clinical pathways were correctly followed. CONCLUSIONS: Implementation of clinical pathways for suspected ACS reduced the length of stay and increased the proportions of patients safely discharged within 6 hours.

Advancing leadership in Australasian emergency medicine: Taking stock and looking ahead.

Since 2018, the Australasian College for Emergency Medicine has collaborated with the Swinburne University of Technology on a research project to understand and enhance the leadership capacity of emergency physicians, beginning with Australasian Directors of Emergency Medicine (DEMs). Over the last 3 years, this research programme has revealed the complexity of leadership in emergency medicine, illuminating the strengths and limitations of extant research and suggesting promising new directions for emergency medicine leadership and leadership development research. This programme has also shed new light on the knowledge, skills and abilities that DEMs need to develop to catalyse change in the systems where DEMs practice both medicine and leadership. We propose that an approach to leadership development that reflects the diversity of DEMs' leadership challenges and the complexity of leadership in emergency medicine would go a long way to enhancing the sophistication, effectiveness and impact of the leadership in emergency medicine.

Safer coalmines, happier, healthier and more engaged canaries.

Addressing and limiting burnout and its significant impacts on emergency physicians is an important and ongoing challenge, requiring much more than a focus on individual resilience. This is a key understanding which guides and informs the Australasian College for Emergency Medicine's holistic approach and advocacy efforts when it comes to the wellness of emergency physicians and the health systems in which they operate.

Early lessons from COVID-19 that may reduce future emergency department crowding.

The COVID-19 pandemic has produced significant changes in emergency medicine patient volumes, clinical practice, and has accelerated a number of systems-level developments. Many of these changes produced efficiencies in emergency care systems and contributed to a reduction in crowding and access block. In this paper, we explore these changes, analyse their risks and benefits and examine their sustainability for the future to the extent that they may combat crowding. We also examine the necessity of a system-wide approach in addressing ED crowding and access block.

Emergency and stroke physician combined consensus statement on thrombolysis for acute stroke.

The New Zealand Faculty of the Australasian College for Emergency Medicine (ACEM) is the professional body representing the specialist emergency medicine physicians who work in and lead emergency departments of New Zealand. The National Stroke Network Leadership Group represents New Zealand stroke clinicians including stroke physicians and neurologists who work within and lead district health board (DHB) stroke services. In an effort to promote their shared goal of ensuring patient safety while striving to achieve improved stroke outcomes, the two communities have set up a consensus group to develop this combined emergency physician and neurologist/stroke physician consensus statement on the use of intravenous alteplase in stroke ('stroke thrombolysis').

Meningococcal disease deaths and the frequency of antibiotic administration delays.

OBJECTIVE: Meningococcal disease (MCD) remains a medical emergency and a frequent cause of death in previously healthy individuals. We aimed to determine the frequency and cause of delays in antibiotic administration in a cohort of deaths. METHODS: A retrospective chart review was undertaken on 140 hospitalised MCD deaths within New Zealand's serogroup B epidemic (1993-2004). RESULTS: Death after hospital presentation occurred rapidly (median 12 h) with 70% dying within 24 h. Delays of more than 2 h in time-to-antibiotic post hospital presentation occurred in 29%. The major contributors to these delays were the failure to include MCD within the differential diagnosis and prolonged assessment times. Multivariate logistic regression analysis, undertaken by combining study deaths which had meningococcal bacterial load results (n=9) with a survivor cohort (n=126) from a previous study, confirmed bacterial load as a major predictor of death (OR 7.5 per log10 cfu/mL increase; 95% CI 2.2-25.3; p=0.001). A non-significant increased risk of death per hour of antibiotic delay was seen (OR 1.18; 95% CI 0.90-1.55; p=0.22). CONCLUSIONS: Death from MCD occurred rapidly, with many patients not receiving antibiotics at the earliest opportunity. The introduction of recently developed rapid diagnostic markers into the identified delay-intervals could lead to a reduction in time-to-antibiotic and hopefully reduce case-fatality rates.
