An evidence-based approach to managing gunshot wounds in the emergency department.

Education regarding ballistic injuries in the emergency department is sparse and may rarely be encountered if not training or practicing in a trauma center or a military wartime setting. This article provides a comprehensive review on the management of ballistic injuries in the emergency department, including how to assess and manage gunshot wounds, how to recognize when further imaging or evaluation is needed, and how to recognize when transfer to another facility is required. Algorithms are proposed for the management of gunshot wounds based on body part: head, neck, chest and abdomen, and extremities/soft tissue.

Geriatric Trauma.

Geriatric trauma patients will continue to increase in prevalence as the population ages, and many specific considerations need to be made to provide appropriate care to these patients. This article outlines common presentations of trauma in geriatric patients, with consideration to baseline physiologic function and patterns of injury that may be more prevalent in geriatric populations. Additionally, the article explores specific evidence-based management practices, the significance of trauma team and geriatrician involvement, and disposition decisions.

Improving out-of-hospital notification in traumatic cardiac arrests with novel usage of smartphone application.

INTRODUCTION: Timely out-of-hospital notifications in patients with traumatic cardiac arrest are associated improvements in mortality. Details surrounding these events are often limited, and decisions to perform advanced resuscitative procedures must be made based on limited data. This study evaluated the ability of a mobile application (app) called Citizen (sp0n Inc., New York, NY) to address these issues by providing a novel, secondary source of out-of-hospital information in traumatic cardiac arrest. Citizen sends notifications to mobile devices in response to nearby detected public safety events, and we sought to evaluate its utility in prenotification for traumatic cardiac arrest. METHODS: This was a retrospective observational study. Patients ≥ 15 years of age with traumatic cardiac arrest attributed to penetrating trauma were included. The 2 coprimary outcomes observed were the time difference between the app notification and emergency medical services notification, and the app's success rate in generating a notification for each patient in traumatic cardiac arrest. RESULTS: From February 2, 2019 to October 10, 2019, there were 43 patients who met the criteria for this study. On average, the Citizen app notification arrived 12.9 minutes before emergency medical services radio notification (95% confidence interval, 9.2-16.6; P < 0.001). Citizen generated a notification for 36 of 43 patients (84%). CONCLUSION: The Citizen app generates earlier notifications in traumatic cardiac arrest compared with standard radio communications. It also provides a previously unavailable secondary source of information for making rapid resuscitative decisions upon the arrival of the arresting patient to the emergency department. Further research is needed to determine how to optimally integrate the app into existing trauma systems.
