OBJECTIVE:This study aims to identify interventions to address workplace violence in the emergency department based on direct evidence from experiences of patient assault. METHODS:We performed de novo coding and thematic analysis of datasets from two geographically distinct institutions and five different sites that contained interviews with 80 health workers. RESULTS:We identified concepts that corresponded to the micro (workers and patients), meso (organizations and clinical units), and macro (society at large, worldviews, and values) levels of the healthcare system. Within each level, potential interventions fell into the prevention, response, and recovery phases of emergency preparedness. CONCLUSION:Efforts to address workplace violence should consider interconnected influences from individual workers, organizations, and society at large. Comprehensive approaches at multiple phases of preparedness are needed to have sustained impact on safety.

IMPORTANCE:Delirium is common among older emergency department (ED) patients, is associated with high morbidity and mortality, and frequently goes unrecognized. Anecdotal evidence has described atypical presentations of coronavirus disease 2019 (COVID-19) in older adults; however, the frequency of and outcomes associated with delirium in older ED patients with COVID-19 infection have not been well described. OBJECTIVE:To determine how frequently older adults with COVID-19 present to the ED with delirium and their associated hospital outcomes. DESIGN, SETTING, AND PARTICIPANTS:This multicenter cohort study was conducted at 7 sites in the US. Participants included consecutive older adults with COVID-19 presenting to the ED on or after March 13, 2020. EXPOSURE:COVID-19 was diagnosed by positive nasal swab for severe acute respiratory syndrome coronavirus 2 (99% of cases) or classic radiological findings (1% of cases). MAIN OUTCOMES AND MEASURES:The primary outcome was delirium as identified from the medical record according to a validated record review approach. RESULTS:A total of 817 older patients with COVID-19 were included, of whom 386 (47%) were male, 493 (62%) were White, 215 (27%) were Black, and 54 (7%) were Hispanic or Latinx. The mean (SD) age of patients was 77.7 (8.2) years. Of included patients, 226 (28%) had delirium at presentation, and delirium was the sixth most common of all presenting symptoms and signs. Among the patients with delirium, 37 (16%) had delirium as a primary symptom and 84 (37%) had no typical COVID-19 symptoms or signs, such as fever or shortness of breath. Factors associated with delirium were age older than 75 years (adjusted relative risk [aRR], 1.51; 95% CI, 1.17-1.95), living in a nursing home or assisted living (aRR, 1.23; 95% CI, 0.98-1.55), prior use of psychoactive medication (aRR, 1.42; 95% CI, 1.11-1.81), vision impairment (aRR, 1.98; 95% CI, 1.54-2.54), hearing impairment (aRR, 1.10; 95% CI 0.78-1.55), stroke (aRR, 1.47; 95% CI, 1.15-1.88), and Parkinson disease (aRR, 1.88; 95% CI, 1.30-2.58). Delirium was associated with intensive care unit stay (aRR, 1.67; 95% CI, 1.30-2.15) and death (aRR, 1.24; 95% CI, 1.00-1.55). CONCLUSIONS AND RELEVANCE:In this cohort study of 817 older adults with COVID-19 presenting to US emergency departments, delirium was common and often was seen without other typical symptoms or signs. In addition, delirium was associated with poor hospital outcomes and death. These findings suggest the clinical importance of including delirium on checklists of presenting signs and symptoms of COVID-19 that guide screening, testing, and evaluation.

Medical rapid response teams, now ubiquitous throughout hospitals, were designed to identify and proactively treat early warning signs of acute medical decompensation. Behavioral emergencies-including clinical psychiatric emergencies, coping/stress reactions, and iatrogenic injuries-are not responded to with the same vigor. At worst, behavioral crises are treated as unarmed security threats. Limited or inappropriate responses to such crises can lead to suboptimal outcomes on numerous levels, especially avoidable harm to patients and frontline clinicians. Widespread implementation of behavioral emergency response teams for patient-centered behavioral interventions has been impeded by a pervasive perception that these endeavors are medically unnecessary and optional. This article calls for a paradigm shift in responding to behavioral emergencies by arguing that security-driven risk management practices during behavioral emergencies are incompatible with fundamental medical and ethics principles.

BACKGROUND:The emergency department (ED) relies on high-functioning teams to deliver consistent and safe patient care. Experts recommend that both emergency physicians and ED nurses participate in team training. However, there are currently no nationally accepted curricula for either profession to embed this training in their professional development, particularly for health workers who are novice or transitioning into critical care roles. METHODS:An interprofessional educator team designed and embedded a series of simulation scenarios within a novel orientation program for novice nurses transitioning to critical care roles in the ED to teach clinical and teamwork skills for conjoint groups of resident physician and novice nurse learners. The team created four interprofessional simulations to represent the acuity and breadth of patient populations in the ED critical care bays. INTERVENTION/REFINEMENT:To date, the team has conducted 24 two-week orientation sessions for 48 nurses and 51 resident physicians. Overall mean scores for the Debriefing Assessment for Simulation in Healthcare (DASH) instrument from nursing participants in the first 18 sessions were high. Qualitative evaluation data from both nurses and physicians demonstrated a positive impact of the simulations and provided insight into respective roles, identities, and priorities across professions. Participant feedback led to iterative steps in refinement of the simulations, including adjustments in debriefings and logistics of the orientation program. IMPLICATIONS FOR PRACTICE:A team-based interprofessional simulation program was found to be feasible and acceptable for practicing novice physicians and nurses as part of a nursing critical care orientation program in the ED. Future work will assess the program's long-term impact on teamwork and safety in the actual clinical environment.

Agitated patients presenting to the emergency department (ED) can escalate to aggressive and violent behaviors with the potential for injury to themselves, ED staff, and others. Agitation is a nonspecific symptom that may be caused by or result in a life-threatening condition. Project BETA (Best Practices in the Evaluation and Treatment of Agitation) is a compilation of the best evidence and consensus recommendations developed by emergency medicine and psychiatry experts in behavioral emergencies to improve our approach to the acutely agitated patient. These recommendations focus on verbal de-escalation as a first-line treatment for agitation; pharmacotherapy that treats the most likely etiology of the agitation; appropriate psychiatric evaluation and treatment of associated medical conditions; and minimization of physical restraint/seclusion. Implementation of Project BETA in the ED can improve our ability to manage a patient's agitation and reduce the number of physical assaults on ED staff. This article summarizes the BETA guidelines and recent supporting literature for managing the acutely agitated patient in the ED followed by a discussion of how a large county hospital integrated these recommendations into daily practice.

INTRODUCTION:Emergency department (ED) visits for behavioural conditions are rising, with 1.7 million associated episodes of patient agitation occurring annually in acute care settings. When de-escalation techniques fail during agitation management, patients are subject to use of physical restraints and sedatives, which are associated with up to 37% risk of hypotension, apnoea and physical injuries. At the same time, ED staff report workplace violence due to physical assaults during agitation events. We recently developed a theoretical framework to characterise ED agitation, which identified teamwork as a critical component to reduce harm. Currently, no structured team response protocol for ED agitation addressing both patient and staff safety exists. METHODS AND ANALYSIS:Our proposed study aims to develop and implement the agitation code team (ACT) response intervention, which will consist of a standardised, structured process with defined health worker roles/responsibilities, work processes and clinical protocols. First, we will develop the ACT response intervention in a two-step design loop; conceptual design will engage users in the creation of the prototype, and iterative refinement will occur through in situ simulated agitated patient encounters in the ED to assess and improve the design. Next, we will pilot the intervention in the clinical environment and use a controlled interrupted time series design to evaluate its effect on our primary outcome of patient restraint use. The intervention will be considered efficacious if we effectively lower the rate of restraint use over a 6-month period. ETHICS AND DISSEMINATION:Ethical approval by the Yale University Human Investigation Committee was obtained in 2019 (HIC #2000025113). Results will be disseminated through peer-reviewed publications and presentations at scientific meetings for each phase of the study. If this pilot is successful, we plan to formally integrate the ACT response intervention into clinical workflows at all EDs within our entire health system.

The coronavirus disease 2019 (COVID-19) pandemic caused by the coronavirus SARS-CoV-2 has radically altered delivery of care in emergency settings. Unprecedented hardship due to ongoing fears of exposure and threats to personal safety, along with societal measures enacted to curb disease transmission, have had broad psychosocial impact on patients and healthcare workers alike. These changes can significantly affect diagnosing and managing behavioral emergencies such as agitation in the emergency department. On behalf of the American Association for Emergency Psychiatry, we highlight unique considerations for patients with severe behavioral symptoms and staff members managing symptoms of agitation during COVID-19. Early detection and treatment of agitation, precautions to minimize staff hazards, coordination with security personnel and psychiatric services, and avoidance of coercive strategies that cause respiratory depression will help mitigate heightened risks to safety caused by this outbreak.

INTRODUCTION/BACKGROUND:Tranexamic acid (TXA) is an antifibrinolytic agent currently approved and utilized in the treatment of dysfunctional uterine bleeding, traumatic extracranial hemorrhage, anterior epistaxis, and dental procedures on patients with hemophilia. There is a paucity of literature evaluating the use of TXA for hemostasis in patients on direct oral anticoagulants (DOACs). CASE REPORT/METHODS:Our patient, a 72 year-old male on rivaroxaban, presented with persistent bleeding following a punch biopsy of the buccal mucosa. Given the site of bleeding, inability to effectively tamponade, patient's anticoagulated state, and risk of impending airway compromise, a dressing was soaked with 500 milligram (mg) of TXA and was held in place with pressure using a makeshift clamp until a thrombus formed. Hemostasis was achieved preventing the need for acute ENTotolaryngologic intervention and/or intubation. The patient was observed in the medical setting overnight and discharged home without any recurrence of bleeding or adverse events. DISCUSSION/CONCLUSIONS:This case report describes our experience achieving hemostasis for an otherwise uncontrollable oral bleed in an anticoagulated patient on a DOAC who could not be reversed. Intervention is simple to perform, cost-effective, and requires few resources which are readily available in most emergency departments. CONCLUSION/CONCLUSIONS:We report a novel application of TXA to control an oral mucosal bleed in an anticoagulated patient which was on a DOAC refractory to traditional measures.

Simulation has been steadily changing the safety culture in the healthcare industry and allowing individual clinicians and interdisciplinary teams to be proactive in the culture of risk reduction and improved patient safety. Literature has demonstrated improved patient outcomes, improved team based skills, systems testing and mitigation of latent safety threats. Simulation may be incorporated into practice via different modalities. The simulation lab is helpful for individual procedures, in situ simulation (ISS) for system testing and teamwork, community outreach ISS for sharing of best practices and content resource experts. Serious medical gaming is developing into a useful training adjunct for the future.
