Objective: Relatively little has been reported about the impact of COVID-19 restrictions on emergency ambulance services. We describe the influence of the COVID-19 pandemic on the emergency ambulance system in Victoria, Australia. Methods: We performed an interrupted time series analysis of consecutive calls for ambulance from January 2018 to February 2021, including two waves of COVID-19. ⋯ Conclusion: The COVID-19 pandemic had a dramatic impact on the emergency ambulance system. Despite lower call volumes post-lockdown than predicted, we observed deteriorating ambulance response times, extended case times and hospital delays. The pattern of attendance to patients with suspected ACS potentially highlights the collateral burden of delaying treatment for urgent conditions.

Background: In response to the COVID-19 pandemic, Emergency Medical Services (EMS) systems have received guidelines as part of coordinated response efforts aimed at mitigating exposures and ensuring occupational wellbeing, including recommendations of Personal Protective Equipment (PPE) utilization, and modifications of Emergency Medical Dispatch (EMD) caller queries. The aim of the study was to estimate the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of an EMD telephone screening process for the identification of hospital diagnosed COVID-19 positive patients. Methods: A retrospective cohort study was conducted of adult EMS encounters presenting to hospitals within a large health system from March 16-June 30, 2020. ⋯ The PPV was 24.3% (95% CI 22.5%, 26.0%), and NPV 88.6% (95% CI 87.0%, 90.3%). Conclusions: The sensitivity of the EMD telephonic screening process was moderately able to identify COVID-19 positive patients. There is a need to reevaluate and revise guidelines and recommendations, specifically modified caller queries, as part of ongoing pandemic emergency response efforts in order to reduce transmissions and maximize patient and provider safety.

Emergency department and hospital discharge status are available for less than 2% of events recorded in the National EMS Information System (NEMSIS) Public Release Research dataset. The purpose of this project was to develop a binary ("dead" vs. "alive") end-of-event outcome indicator for the NEMSIS dataset. ⋯ A binary end-of-event outcome indicator can be determined for 98.6% of 9-1-1 initiated ground EMS scene responses and 89.1% of cardiac arrests included in the NEMSIS dataset. The events with a determinable outcome appear representative of the larger dataset and the end-of-event indicators are generally consistent with reported emergency department outcomes.

The American College of Surgeons Committee on Trauma (ACS-COT), the American College of Emergency Physicians (ACEP), the National Association of State EMS Officials (NASEMSO), the National Association of EMS Physicians (NAEMSP) and the National Association of EMTs (NAEMT) have previously offered varied guidance on the use of ketamine in trauma patients. The following consensus statement represents the collective positions of the ACS-COT, ACEP, NASEMSO, NAEMSP and NAEMT. This updated uniform guidance is intended for use by emergency medical services (EMS) personnel, EMS medical directors, emergency physicians, trauma surgeons, nurses and pharmacists in their treatment of the trauma patient in both the prehospital and hospital setting.

Field identification and treatment of ST-segment elevation myocardial infarction (STEMI) by paramedics is an important component of care for these patients. There is a paucity of studies in the setting of paramedic-identified STEMI. This study investigated mortality and factors associated with mortality in a large state-wide prehospital STEMI sample. ⋯ Being overweight was associated with lower 30-day mortality. Conclusions: Mortality in STEMI patients identified and treated by paramedics was low, and the prehospital fibrinolysis treatment pathway was effective with a mortality rate comparable to that of patients undergoing primary PCI. Key words: prehospital; Queensland; cardiac reperfusion; STEMI.
