2021 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations: Summary From the Basic Life Support; Advanced Life Support; Neonatal Life Support; Education, Implementation, and Teams; First Aid Task Forces; and the COVID-19 Working Group.

The International Liaison Committee on Resuscitation initiated a continuous review of new, peer-reviewed published cardiopulmonary resuscitation science. This is the fifth annual summary of the International Liaison Committee on Resuscitation International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations; a more comprehensive review was done in 2020. This latest summary addresses the most recently published resuscitation evidence reviewed by International Liaison Committee on Resuscitation task force science experts. Topics covered by systematic reviews in this summary include resuscitation topics of video-based dispatch systems; head-up cardiopulmonary resuscitation; early coronary angiography after return of spontaneous circulation; cardiopulmonary resuscitation in the prone patient; cord management at birth for preterm and term infants; devices for administering positive-pressure ventilation at birth; family presence during neonatal resuscitation; self-directed, digitally based basic life support education and training in adults and children; coronavirus disease 2019 infection risk to rescuers from patients in cardiac arrest; and first aid topics, including cooling with water for thermal burns, oral rehydration for exertional dehydration, pediatric tourniquet use, and methods of tick removal. Members from 6 International Liaison Committee on Resuscitation task forces have assessed, discussed, and debated the quality of the evidence, according to the Grading of Recommendations Assessment, Development, and Evaluation criteria, and their statements include consensus treatment recommendations or good practice statements. Insights into the deliberations of the task forces are provided in Justification and Evidence-to-Decision Framework Highlights sections. In addition, the task forces listed priority knowledge gaps for further research.

Removal of the Prehospital Tourniquet in the Emergency Department.

BACKGROUND: Life-threatening hemorrhage from extremity injuries can be effectively controlled in the prehospital environment through direct pressure, wound packing, and the use of tourniquets. Early tourniquet application has been prioritized for rapid control of severe extremity hemorrhage and is a cornerstone of prehospital trauma resuscitation guidelines. Emergency physicians must be knowledgeable regarding the initial assessment and appropriate management of patients who present with a prehospital tourniquet in place. DISCUSSION: An interdisciplinary group of experts including emergency physicians, trauma surgeons, and tactical and Emergency Medical Services physicians collaborated to develop a stepwise approach to the assessment and removal (discontinuation) of an extremity tourniquet in the emergency department after being placed in the prehospital setting. We have developed a best-practices guideline to serve as a resource to aid the emergency physician in how to safely remove a tourniquet. The guideline contains five steps that include: 1) Determine how long the tourniquet has been in place; 2) Evaluate for contraindications to tourniquet removal; 3) Prepare for tourniquet removal; 4) Release the tourniquet; and 5) Monitor and reassess the patient. CONCLUSION: These steps outlined will help emergency medicine clinicians appropriately evaluate and manage patients presenting with tourniquets in place. Tourniquet removal should be performed in a systematic manner with plans in place to immediately address complications.

2019 American Heart Association and American Red Cross Focused Update for First Aid: Presyncope: An Update to the American Heart Association and American Red Cross Guidelines for First Aid.

This 2019 focused update to the American Heart Association and American Red Cross first aid guidelines follows the completion of a systematic review of treatments for presyncope of vasovagal or orthostatic origin. This review was commissioned by the International Liaison Committee on Resuscitation and resulted in the development of an international summary statement of the International Liaison Committee on Resuscitation First Aid Task Force Consensus on Science With Treatment Recommendations. This focused update highlights the evidence supporting specific interventions for presyncope of orthostatic or vasovagal origin and recommends the use of physical counterpressure maneuvers. These maneuvers include the contraction of muscles of the body such as the legs, arms, abdomen, or neck, with the goal of elevating blood pressure and alleviating symptoms. Although lower-body counterpressure maneuvers are favored over upper-body counterpressure maneuvers, multiple methods can be beneficial, depending on the situation.

Bleeding Control Protections Within US Good Samaritan Laws.

INTRODUCTION: In the United States, all 50 states and the District of Columbia have Good Samaritan Laws (GSLs). Designed to encourage bystanders to aid at the scene of an emergency, GSLs generally limit the risk of civil tort liability if the care is rendered in good faith. Nation-wide, a leading cause of preventable death is uncontrolled external hemorrhage. Public bleeding control initiatives aim to train the public to recognize life-threatening external bleeding, perform life-sustaining interventions (including direct pressure, tourniquet application, and wound packing), and to promote access to bleeding control equipment to ensure a rapid response from bystanders. METHODS: This study sought to identify the GSLs in each state and the District of Columbia to identify what type of responder is covered by the law (eg, all laypersons, only trained individuals, or only licensed health care providers) and if bleeding control is explicitly included or excluded in their Good Samaritan coverage. RESULTS: Good Samaritan Laws providing civil liability qualified immunity were identified in all 50 states and the District of Columbia. One state, Oklahoma, specifically includes bleeding control in its GSLs. Six states - Connecticut, Illinois, Kansas, Kentucky, Michigan, and Missouri - have laws that define those covered under Good Samaritan immunity, generally limiting protection to individuals trained in a standard first aid or resuscitation course or health care clinicians. No state explicitly excludes bleeding control from their GSLs, and one state expressly includes it. CONCLUSION: Nation-wide across the United States, most states have broad bystander coverage within GSLs for emergency medical conditions of all types, including bleeding emergencies, and no state explicitly excludes bleeding control interventions. Some states restrict coverage to those health care personnel or bystanders who have completed a specific training program. Opportunity exists for additional research into those states whose GSLs may not be inclusive of bleeding control interventions.

A framework for the design and implementation of Stop the Bleed and public access trauma equipment programs.

Traumatic injuries remain the leading cause of death for those under the age of 44 years old. Nearly a third of those who die from trauma do so from bleeding. Reducing death from severe bleeding requires training in the recognition and treatment of life-threatening bleeding, as well as programs to ensure immediate access to bleeding control resources. The Stop the Bleed (STB) initiative seeks to educate and empower people to be immediate responders and provide control of life-threatening bleeding until emergency medical services arrive. Well-planned and implemented STB programs will help ensure program effectiveness, minimize variability, and provide long-term sustainment. Comprehensive STB programs foster consistency, promote access to bleeding control education, contain a framework to guide the acquisition and placement of equipment, and promote the use of these resources at the time of a bleeding emergency. We leveraged the expertise and experience of the Stop the Bleed Education Consortium to create a resource document to help inform and guide STB program developers and implementers on the key areas for consideration when crafting strategy. These areas include (1) equipment selection, (2) logistics and kit placement, (3) educational program accessibility and implementation, and (4) program oversight, facilitation, and administration.

The FAST VIP (First Aid for Severe Trauma "Virtual" in-Person) Educational Study.

INTRODUCTION: Trauma is the leading cause of death for young Americans. Increased school violence, combined with an emphasis on early hemorrhage control, has boosted demand to treat injuries in schools. Meanwhile, coronavirus disease 2019 (COVID-19) has made educating the public about trauma more difficult. A federally funded high school education program in development, called First Aid for Severe Trauma™ (FAST™), will teach students to aid the severely injured. The program will be offered in instructor-led, web-based, and blended formats. We created a program to prepare high school teachers to become FAST instructors via "virtual" in-person (VIP) instruction. We used a webinar followed by VIP skills practice, using supplies shipped to participants' homes. To our knowledge, no prior studies have evaluated this type of mass, widely distributed, VIP education. METHODS: This study is a prospective, single-arm, educational cohort study. We enrolled a convenience sample of all high school teachers attending FAST sessions at the Health Occupations Students of America-Future Health Professionals International Leadership Conference. Half of the participants were randomized to complete the Stop the Bleed Education Assessment Tool (SBEAT) prior to the webinar, and the other completed it afterward; SBEAT is a validated tool to measure learning of bleeding competencies. We then performed 76 VIP video-training sessions from June-August 2020. The FAST instructors assessed each participant's ability to apply a tourniquet and direct pressure individually, then provided interactive group skills training, and finally re-evaluated each participant's performance post-training. RESULTS: A total of 190 (96%) participants successfully applied a tourniquet after VIP training, compared to 136 (68%) prior to training (P < 0.001). Participants significantly improved their ability to apply direct pressure: 116 (56%) pre-assessment vs 204 (100%) post-assessment (P < 0.001). The mean score for the SBEAT increased significantly from pre-training to post-training: 2.09 with a standard deviation (SD) of 0.97 to 2.55 post-training with a SD of 0.72 (P < 0.001). CONCLUSION: This study suggests that a webinar combined with VIP training is effective for teaching tourniquet and direct-pressure application skills, as well as life-threatening bleeding knowledge. VIP education may be useful for creating resuscitative medicine instructors from distributed locations, and to reach learners who cannot attend classroom-based instruction.

Appropriate Tourniquet Types in the Pediatric Population: A Systematic Review.

Trauma is the leading cause of mortality in those aged 1-19, with hemorrhage accounting for up to 40% of all trauma deaths. Manufactured tourniquets are recommended for the control of life-threatening extremity hemorrhage in adults but their use in the pediatric population requires further investigation. We performed a systematic review to evaluate the most appropriate tourniquet design for use in the pediatric population. A literature search of Embase and the Cochran databases of trials and systematic reviews on October 1, 2020 identified 454 unique references, of which 15 were included for full-text screening. Two single-arm observational studies with a high risk of bias evaluated the use of windlass tourniquets in the pediatric population (73 patients, age 2-16 years). The certainty of the evidence was very low. In both studies, conducted on uninjured extremities, the use of a manufactured windlass tourniquet, specifically the Combat Application Tourniquet (C-A-T®) Generation 7, led to the cessation of Doppler detected pulses in 71/71 (100%) of upper extremities and 69/73 (94.5%) of lower extremities. Of the four failures, one participant withdrew due to pain and three tourniquet applications failed to occlude pulses after three turns of the windlass. No controls were used for comparison. In conclusion, two observational studies demonstrated that windlass tourniquets were able to abolish distal pulses in children as young as two years of age and with a minimum limb circumference of 13 cm. These preliminary findings may be helpful for organizations in the creation of guidelines for the management of life-threatening extremity bleeding in children.

Brief, Web-based Education Improves Lay Rescuer Application of a Tourniquet to Control Life-threatening Bleeding.

OBJECTIVE: The objective was to determine whether brief, Web-based instruction several weeks prior to tourniquet application improves layperson success compared to utilizing just-in-time (JiT) instructions alone. BACKGROUND: Stop the Bleed is a campaign to educate laypeople to stop life-threatening hemorrhage. It is based on U.S. military experience with lifesaving tourniquet use. While previous research shows simple JiT instructions boost laypeople's success with tourniquet application, the optimal approach to educate the public is not yet known. METHODS: This is a prospective, nonblinded, randomized study. Layperson participants from the Washington, DC, area were randomized into: 1) an experimental group that received preexposure education using a website and 2) a control group that did not receive preexposure education. Both groups received JiT instructions. The primary outcome was the proportion of subjects that successfully applied a tourniquet to a simulated amputation. Secondary outcomes included mean time to application, mean placement position, ability to distinguish bleeding requiring a tourniquet from bleeding requiring direct pressure only, and self-reported comfort and willingness to apply a tourniquet. RESULTS: Participants in the preexposure group applied tourniquets successfully 75% of the time compared to 50% success for participants with JiT alone (p < 0.05, risk ratio = 1.48, 95% confidence interval = 1.21-1.82). Participants place tourniquets in a timely fashion, are willing to use them, and can recognize wounds requiring tourniquets. CONCLUSIONS: Brief, Web-based training, combined with JiT education, may help as many as 75% of laypeople properly apply a tourniquet. These findings suggest that this approach may help teach the public to Stop the Bleed.

A Retrospective Review of Screening Labs for Medical Clearance in a Military Population.

STUDY OBJECTIVE: We determine the incidence of clinically significant findings within mandatory screening studies during medical clearance of patients for psychiatric care. METHODS: This is a retrospective review of emergency department patients medically cleared for psychiatric care over 11 months. All patients evaluated for behavioral health-related issues are recorded on a daily report which was used to locate subjects. Laboratory studies were reviewed during that visit for the presence of abnormalities. If abnormalities were noted, the individual chart was reviewed. Our primary outcome was the incidence of clinically significant findings that warranted admission to a medical or surgical unit. RESULTS: 204 psychiatric patient reports were reviewed. 191 of these patients had screening studies performed. Seven patients were admitted to a nonpsychiatric unit. These admissions were all for elevated ethanol levels. These patients were admitted until their ethanol level decreased, and then transferred to a psychiatric facility. The total screening lab cost during this study period was $27,893. CONCLUSIONS: Routine screening has limited utility in this population and comes at significant cost. Further research should be directed to determine which patients may benefit from screening studies.

Hybrid simulation improves medical student procedural confidence during EM clerkship.

BACKGROUND: Medical students have limited opportunities to perform and learn procedures on live patients. This is particularly concerning at the Uniformed Services University of the Health Sciences (USUHS), where graduates may be assigned to an operational military unit immediately following completion of internship. The authors implemented a new hybrid simulation lab for fourth-year medical students at the Uniformed Services University of the Health Sciences consisting of procedural skills training for seven core emergency medicine skills combined with complex patient cases using high fidelity simulators and standardized patients. OBJECTIVES: Measure changes in student procedural skills confidence due to the new hybrid simulation curriculum. METHODS: This observational study used anonymous 5-point Likert-anchored questionnaires to measure student confidence at three different times: immediately before hybrid simulation training, immediately after training, and 3 weeks post-training. RESULTS: Pretraining student confidence was 3.0 (out of 5) when averaged for all seven procedures. This improved to 4.2 immediately after training, and remained high (4.1) 3 weeks later at the end of the clerkship. Students retained this improved confidence despite performing few procedures on real patients during their clerkships. The training demonstrated statistically significant confidence improvement for all procedures, except bag-valve mask ventilation. CONCLUSIONS: Hybrid simulation training improves student confidence with procedural skills during an emergency medicine clerkship.

Value of mandatory screening studies in emergency department patients cleared for psychiatric admission.

INTRODUCTION: Laboratory and radiographic studies are often required by psychiatric services prior to admitting emergency patients who are otherwise deemed medically stable. Such testing may represent an unnecessary expense that prolongs emergency department stays without significantly improving care. This study determines the prevalence of such testing and how often it leads to changes in care. METHODS: We prospectively tracked laboratory testing among psychiatric patients presenting to the emergency departments of two academic tertiary care facilities. For each visit we determined whether laboratory or radiographic studies were ordered, and whether the examination was conducted at the request of the emergency physician as part of a medical screening examination or requested by the psychiatry service. We then determined if this testing changed patient disposition. RESULTS: Our study enrolled 598 patients. Of these, emergency physicians ordered testing as a part of medical screening on 155 patients (25.9%). We found the psychiatry service ordered laboratory or radiographic studies for 191 of 434 patients (44.0%) who emergency physicians determined did not require ancillary testing for medical clearance. Of these 191 patients, only one (0.5%; 95% Confidence Interval: 0.01% - 2.9%) had an abnormal result that led to a change in disposition. Total Medicare reimbursement rates for the additional ancillary testing in this study was $37,682. CONCLUSION: Ancillary testing beyond what is required for medical clearance of psychiatric emergency patients rarely alters care. Policies that require panels of testing prior to psychiatric admission are costly and appear to be unnecessary.
