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

First-aid training for primary Healthcare providers on a remote Island: a mixed-methods study

BACKGROUND

Ensuring ongoing first-aid training for primary healthcare providers (PHPs) is one of the critical strategies for providing quality health services and contributing to achieving universal health coverage. However, PHPs have received insufficient attention in terms of training and capacity building, especially in the remote areas of low-to-middle-income countries. This study evaluated the effectiveness of a first-aid training program for PHPs on a Vietnamese island and explored their perspectives and experiences regarding first-aid implementation.

METHODS

A mixed-methods study was conducted among 39 PHPs working in community healthcare centers. The quantitative method utilized a quasi-experimental design to evaluate participants' first-aid knowledge at three time points: pre-training, immediately post-training, and three months post-training. Sixteen of the PHPs participated in subsequent semi-structured focus group interviews using the qualitative method. Quantitative data were analyzed using repeated measures analysis of variance (ANOVA), while qualitative data were subjected to thematic analysis.

RESULTS

The quantitative results showed a significant improvement in both the overall mean first-aid knowledge scores and the subdimensions of the first-aid knowledge scores among healthcare providers post-training. There was a statistically significant difference between the baseline and immediate posttest and follow-up knowledge scores (p < 0.001). However, the difference in knowledge scores between the immediate posttest and three-month follow-up was not significant (p > 0.05). Three main themes emerged from the focus group discussions: perception of first-aid in remote areas, facilitators and barriers. Participants identified barriers, including infrastructure limitations, shortage of the primary healthcare workforce, inadequate competencies, and insufficient resources. Conversely, receiving considerable support from colleagues and the benefits of communication technologies in implementing first aid were mentioned as facilitators. The training bolstered the participants' confidence in their first-aid responses, and there was a desire for continued education.

CONCLUSIONS

Implementing periodic first-aid refresher training for PHPs in a nationwide resource-limited setting can contribute significantly to achieving universal health coverage goals. This approach potentially enhances the preparedness of healthcare providers in these areas to deliver timely and effective first aid during emergencies, which may lead to more consistent primary healthcare services despite various challenges.

Recommendations for Placement of Bleeding Control Kits in Public Spaces-A Simulation Study

OBJECTIVE

Bleeding control measures performed by members of the public can prevent trauma deaths. Equipping public spaces with bleeding control kits facilitates these actions. We modeled a mass casualty incident to investigate the effects of public bleeding control kit location strategies.

METHODS

We developed a computer simulation of a bomb exploding in a shopping mall. We used evidence and expert opinion to populate the model with parameters such as the number of casualties, the public's willingness to aid, and injury characteristics. Four alternative placement strategies of public bleeding control kits in the shopping mall were tested: co-located with automated external defibrillators (AEDs) separated by 90-second walking intervals, dispersed throughout the mall at 10 locations, located adjacent to 1 exit, located adjacent to 2 exits.

RESULTS

Placing bleeding control kits at 2 locations co-located with AEDs resulted in the most victims surviving (18.2), followed by 10 kits dispersed evenly throughout the mall (18.0). One or 2 kit locations placed at the mall's main exits resulted in the fewest surviving victims (15.9 and 16.1, respectively).

CONCLUSIONS

Co-locating bleeding control kits with AEDs at 90-second walking intervals results in the best casualty outcomes in a modeled mass casualty incident in a shopping mall.

The Effects of Stress on Tourniquet Application and CPR Performance in Layperson and Professional Civilian Populations

OBJECTIVE

The purpose of this study was to compare laypeople's and professional first responders' ability to perform tourniquet application and cardiopulmonary resuscitation (CPR) during calm and stressful circumstances.

BACKGROUND

Life-threatening bleeding is a major cause of death that could be prevented by fast and appropriate first aid interventions. Therefore, laypeople are now being trained in bleeding control skills, transforming them from bystanders to immediate responders. However, critics have questioned whether laypeople are able to perform during more stressful conditions.

METHOD

Twenty-four laypersons and 31 professional first responders were tested in two conditions: a calm classroom scenario and a stressful scenario consisting of paintball fire and physical exertion. Stress and workload were assessed along with task performance.

RESULTS

The experimental manipulation was successful in terms of eliciting stress reactions. Tourniquet application performance did not decline in the stressful condition, but some aspects of CPR performance did for both groups. First responders experienced higher task engagement and lower distress, worry and workload than the laypeople in both the calm and stressful conditions.

CONCLUSION

Stress did not affect first responders and laypeople differently in terms of performance effects. Stress should therefore not be considered a major obstacle for teaching bleeding control skills to laypeople.

APPLICATION

Tourniquet application can be taught to laypeople in a short amount of time, and they can perform this skill during stress in controlled settings. Concerns about laypeople's ability to perform under stress should not exclude bleeding control skills from first aid courses for civilian laypeople.

Effectiveness of "Stop the Bleed" Courses: A Systematic Review and Meta-analysis

OBJECTIVE

Our object was to comprehensively analyze the existing body of evidence to evaluate the Stop the Bleed (STB) course effectiveness and satisfaction and find the direction of improvement for the future.

STUDY DESIGN

A literature search with the term "Stop the Bleed" in the electronic databases PubMed, Web of Science, EMBASE, Cochrane Library was performed, retrieving records from January 1, 2013 to April 13, 2022 based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram. In addition, all selected papers' references were examined for qualified studies that were missed during the first search. Original publications were included that reported on (1) clinical studies of the STB course implementation; and (2) studies comparing students' hemostasis ability and attitude (comfort, confidence, and willingness) before and after the STB course. The literature search and data extraction were done independently by 2 writers. To establish consensus, disagreements will be handled with the help of a third reviewer. For data synthesis, the most inclusive data from studies with repeated data were abstracted. Changes in hemostasis questionnaire scoring and operation evaluation after the STB course were the main outcomes.

RESULTS

This systematic review and meta-analysis includes 36 trials with a total of 11,561 trainees. Thirty-one of them were undertaken in the USA, while the other 5, accounting for 13.9%, were conducted in other regions. Among various evaluation methods, 3 trials with 927 trainees indicated that scores of correct uses of tourniquet significantly increased after the STB course (mean difference of post versus pre groups, 44.28; 95% CI 41.24-47.32; p < 0.001). Significant difference was also observed in the willingness to apply a hemostatic dressing in a real-world situation (risk ratio for post versus pre groups, 1.28; 95% CI 1.08-1.52; p = 0.004) (7 studies and 2360 participants). The results indicate that hemostasis knowledge and skills after the STB course had improved, but statistics indicated that STB courses implemented in the USA were more effective than other regions.

CONCLUSIONS AND RELEVANCE

Meta-analysis showed that comparison before and after the STB course were significantly different. However, the outcome measures in each study were different and could not, therefore, be compiled in all cases. The effectiveness and worth of implementation of STB in different countries should be continuously evaluated in the future.

The Untrained Public's Ability to Apply the Layperson Audiovisual Assist Tourniquet vs a Combat Application Tourniquet: A Randomized Controlled Trial

BACKGROUND

Although the Stop the Bleed campaign's impact is encouraging, gaps remain. These gaps include rapid skill decay, a lack of easy-to-use tourniquets for the untrained public, and training barriers that prevent scalability. A team of academic and industry partners developed the Layperson Audiovisual Assist Tourniquet (LAVA TQ)-the first audiovisual-enabled tourniquet for public use. LAVA TQ addresses known tourniquet application challenges and is novel in its design and technology.

STUDY DESIGN

This study is a prospective, randomized, superiority trial comparing the ability of the untrained public to apply LAVA TQ to a simulated leg vs their ability to apply a Combat Application Tourniquet (CAT). The study team enrolled participants in Boston, MA; Frederick, MD; and Linköping, Sweden in 2022. The primary outcome was the proportion of successful applications of each tourniquet. Secondary outcomes included: mean time to application, placement position, reasons for failed application, and comfort with the devices.

RESULTS

Participants applied the novel LAVA TQ successfully 93% (n = 66 of 71) of the time compared with 22% (n = 16 of 73) success applying CAT (relative risk 4.24 [95% CI 2.74 to 6.57]; p < 0.001). Participants applied LAVA TQ faster (74.1 seconds) than CAT (126 seconds ; p < 0.001) and experienced a greater gain in comfort using LAVA TQ than CAT.

CONCLUSIONS

The untrained public is 4 times more likely to apply LAVA TQ correctly than CAT. The public also applies LAVA TQ faster than CAT and has more favorable opinions about its usability. LAVA TQ's highly intuitive design and built-in audiovisual guidance solve known problems of layperson education and skill retention and could improve public bleeding control.

How to evaluate first aid skills after training: a systematic review

Background

To be able to help and save lives, laypersons are recommended to undergo first aid trainings. The aim of this review was to explore the variety of the elements of the measuring systems to assess the effects of first aid trainings on different aspects of first aid skills including practical skills, knowledge, and emotional perspectives.

Methods

This systematic literature review used Scopus and PubMed databases and searched for studies published between January, 2000, and December, 2020. Out of 2,162 studies meeting the search criteria, 15 studies with quantitative and repeatable evaluation methods to assess first aid skills after first aid training for adults were included in the final analysis.

Results

Practical skills, especially on the ability to perform cardiopulmonary resuscitation (CPR) and to use an automated external defibrillator, were the most studied first aid skills after first aid training. This evaluation was based on several standardized measurements and assessed often with the help of a combination of resuscitation manikin and observer. Evaluation methods of performance in other emergency situations are not well standardized. Questionnaires used to assess knowledge of first aid, though seemingly based on guidelines, were also not standardized, either. Emotional aspects of first aid (willingness or self-confidence) were evaluated by highly simplified questionnaires, and answers were graded by five-point Likert scale.

Conclusion

According to our review, the focus of evaluation methods after first aid training has been on practical skills and especially on CPR. Though the evaluation of first-aid knowledge seems to be straightforward, it is not performed systematically. Evaluation methods for emotional aspects are highly simplified. Overall, standardized measurements and evaluation methods to assess all aspects of first aid skills are needed.

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.

Evaluation of primary care physicians' approaches to hemophilia and bleeding disorders: a questionnaire survey

Bleeding disorders are causes of great concern and panic for parents and primary care providers. Lack of knowledge and awareness on appropriate screening tests and factor product preparation contributed to potential diagnostic delays, increased complications, and economic costs. This study aimed to determine and compare the approach of primary care physicians (including general practitioners) and emergency physicians with a questionnaire including simulation-based cases on hemophilia. This simulation and two-stage questionnaire study was conducted with 244 participants. Before-after questionnaires, two case simulations, a brief presentation, and statistical analysis were performed. Participants mostly preferred tests, such as prothrombin time (PT) or partial thromboplastin time (PTT) to bleeding time for primary hemostasis (PT/PTT n: 192, 84.2%, bleeding time n: 94, 41.2%). Similar results were found for secondary hemostasis (bleeding time n: 144, 63.4%). There was a lack of knowledge in the management of simulation-based cases of acute hemorrhagic complications and factor product preparation (complication case: correct n: 100, 55.2%; initial doses correct n: 56, 43.4%, factor preparing correct n: 37, 49.3%, factor admission correct n: 36, 24.3%). All changed significantly, after the presentation (P = 0.000). Our study shows that there is probably a lack of knowledge of diagnostic investigations and appropriate factor product preparation with possible consequences for patients and economics.

A review on initiatives for the management of daily medical emergencies prior to the arrival of emergency medical services

Emergency services worldwide face increasing cost pressure that potentially limits their existing resources. In many countries, emergency services also face the issues of staff shortage-creating extra challenges and constraints, especially during crisis times such as the COVID-19 pandemic-as well as long distances to sparsely populated areas resulting in longer response times. To overcome these issues and potentially reduce consequences of daily (medical) emergencies, several countries, such as Sweden, Germany, and the Netherlands, have started initiatives using new types of human resources as well as equipment, which have not been part of the existing emergency systems before. These resources are employed in response to medical emergency cases if they can arrive earlier than emergency medical services (EMS). A good number of studies have investigated the use of these new types of resources in EMS systems, from medical, technical, and logistical perspectives as their study domains. Several review papers in the literature exist that focus on one or several of these new types of resources. However, to the best of our knowledge, no review paper that comprehensively considers all new types of resources in emergency medical response systems exists. We try to fill this gap by presenting a broad literature review of the studies focused on the different new types of resources, which are used prior to the arrival of EMS. Our objective is to present an application-based and methodological overview of these papers, to provide insights to this important field and to bring it to the attention of researchers as well as emergency managers and administrators.

Laypeople perception and interpretation of simulated life-threatening bleeding: a controlled experimental study

Introduction

First aid performed by immediate responders can be the difference between life and death in the case of trauma with massive bleeding. To develop effective training programs to teach bleeding control to laypersons, it is important to be aware of beliefs and misconceptions people hold on bleeding and severity of bleeding situations.

Method

A controlled study was conducted in which 175 American college students viewed 78 video clips of simulated bleeding injuries. The volume of blood present (between 0 and 1900 ml), rate of blood flow, and victim gender were systematically varied within participants. Participants were asked to rate injury severity, indicate the appropriate first aid action, and estimate the amount of time until death for the victim.

Results

Though the Stop the Bleed® campaign recommends training laypeople to treat 165 ml of blood loss as life threatening, participants largely rated this volume of blood loss as minimal, mild, or moderate and estimated that the victim had just under one hour to live. Increased blood loss was associated with increased recommendations to use a tourniquet. However, in the 1900 ml conditions, participants still estimated that victims had around 22 minutes to live and approximately 15% recommended direct pressure as the intervention. Severity ratings and recommendations to use a tourniquet were also higher for the male victim than the female victim.

Conclusions

Injury classification, intervention selection, and time to death-estimations revealed that training interventions should connect classifications of blood loss to appropriate action and focus on perceptions of how much time one has to respond to a bleeding. The study also revealed a gender related bias in terms of injury classification and first aid recommendations. Bleeding control training programs can be designed to address identified biases and misconceptions while building on existing knowledge and commonly used terminology.

Development of Novel Video-Based First Responder Opioid Hazard Refresher Training

First responders encounter many hazards in the execution of their duties, and exposure to hazardous materials such as opioids is a primary safety concern. The ongoing opioid crisis in the United States continues to be a major public health issue, with overdose deaths from opioids reaching epidemic levels. Although responders frequently encounter opioids, available data on safety and risk are not always well-communicated, and we identified a need for refresher and just-in-time training products on this topic. In response, we created a training video series that is informative, concise, and visually appealing. The video series, available on YouTube, was tested with a small initial population, with findings suggesting key questions for a larger study focused on integration of the refresher training with existing programs to optimize retention and adoption of safety practices.

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.

Potentially survivable fatal vascular access hemorrhage with tourniquet use: A post-mortem analysis

BACKGROUND

The US military has prioritized battlefield hemorrhage control. Researchers credit tourniquet use, and a novel trauma care training program, with saving 1000-2000 lives in Iraq and Afghanistan. The Stop the Bleed campaign translates these lessons learned to the public. This is the first analysis of the potential impact of this newfound knowledge about tourniquet use for extremity fatal vascular access hemorrhage in a civilian population. Fatal vascular access hemorrhage includes bleeding from arteriovenous fistulas and grafts used for hemodialysis and central venous catheters.

METHODS

This is a retrospective study of decedent records. We selected Maryland death records from 2002-2017 using the following search terms: "graft," "shunt," "fistula," "dialysis," and "central venous catheter." The records were analyzed for potential survivability with a checklist of military criteria modified for a civilian population. Suicides were excluded. Two reviewers independently classified the deaths as either potentially survivable or non-survivable, and a third reviewer broke ties.

RESULTS

There were 111 deaths included in the final analysis. Ninety-two of the 111 decedents had potentially survivable extremity fatal vascular access hemorrhage. The remaining 19 records were excluded, because they did not have extremity hemorrhage. Zero decedents had hemorrhage deemed to be non-survivable with prompt tourniquet application.

CONCLUSION

This study identified 92 Maryland extremity fatal vascular access hemorrhage decedents who potentially could have survived with tourniquet use-an average of 6 per year. These results suggest the need for further epidemiology investigation, as well as exploration of the risks and benefits of teaching and equipping vascular access patients and their caregivers to use tourniquets for life-threatening bleeding.

Increasing the Effectiveness of "Stop the Bleed" Training Through Stepwise Mastery Learning with Deliberate Practice

OBJECTIVE

The Stop the Bleed (STB) Campaign supported by the American College of Surgeons Committee on Trauma (ACSCT) and numerous other national organizations aspires to translate lifesaving military successes into reductions in civilian hemorrhagic deaths. While a curricular framework has been described, precise approaches to hands-on training are not specified and training success rates are not yet optimized. Our aim was to test the feasibility and effectiveness of an STB program enhanced by stepwise mastery learning with deliberate practice.

STUDY DESIGN

Learners participated in an STB program combining evidence-based training models: the Peyton 4-stage model and simulation-based mastery learning with deliberate practice. ASCTC-certified STB coaches used a 3-point, behaviorally explicit checklist to test 4 skills: apply direct pressure; apply standard and improvised tourniquets; pack a wound. An anonymous questionnaire was administered.

SETTING

Simulation Center, Emory University School of Medicine.

PARTICIPANTS

College students (N = 30) with no previous trauma training.

RESULTS

100% of participants reached mastery level for all 4 hemorrhage control skills within 4 tries. Additionally, 87% could state a definitive sign of life-threatening bleeding. 76% predicted comfort using a tourniquet in a real-life emergency; among 6 who would be very uncomfortable, 5 nonetheless would definitely recommend the course.

CONCLUSIONS

We demonstrate feasibility and increased effectiveness of an STB course using evidence-based procedural training techniques. Adopting these techniques in current STB programs could close the current trainee performance gap and substantially increase the annual number of successfully trained laypersons over current reported levels with no increase required in enrollees, programs, or resources. Future studies should address the challenges of knowledge retention and skill decay, just-in-time innovations, implementation science methods to broaden access, and barriers to responding to real-life crisis events. Surgery education leaders can close performance gaps and make a unique contribution to the Hartford Consensus principle: No one should die from uncontrolled bleeding.

Stop the Bleed: The Impact of a Basic Bleeding Control Course on High School Personnel’s Perceptions of Self-Efficacy and School Preparedness

Background: Uncontrolled bleeding is the leading cause of preventable death from trauma. The Stop the Bleed (STB) initiative provides basic education about bleeding to potential immediate responders. The present study aimed to assess the perceptions of self-efficacy and school preparedness related to responding to a life-threatening bleeding emergency in school personnel at an urban high school. Methods: High school personnel from an urban high school ( N = 156) completed a 1-hour STB course that included a didactic and hands-on component. Participants rated their agreement with statements about self-efficacy and school preparedness on a 5-point Likert-type scale, responded to items regarding how school personnel could be better prepared for life-threatening emergencies, and had the option to provide written responses pre- and post-course. Findings: Independent samples t tests revealed that perceptions of self-efficacy and school preparedness increased after the course ( p < .001). Before the course, 87% of participants felt they needed training, 80% felt the school needed clearer procedures, and 74% felt the school required more equipment for a life-threatening bleeding incident compared with 63%, 69%, and 78% post-course, respectively. Thematic analysis of written responses revealed that participants desired higher frequencies of STB training, more equipment, clearer school procedures, and realistic training scenarios with students. Conclusions/Application to Practice: The STB course increased both perceptions of self-efficacy and school preparedness in a sample of high school personnel. Qualitative analyses provided insight to personnel’s opinion of STB’s effectiveness and what is necessary to maintain or follow through with this knowledge after completion of the course.

Educating the Public on Hemorrhage Control: Methods and Challenges of a Public Health Initiative

Purpose of Review

We aim to determine the various models of training and identify educational strategies that would be efficacious in teaching bleeding control to the public.

Recent Findings

Recent studies have examined various educational strategies of bleeding control education including lectures, web-based classes, and hands-on training. The effectiveness of these trainings can not only be measured in increases in knowledge, but also in feelings of confidence, preparedness, and willingness to assist in a bleeding emergency. When looking at retention or skills and knowledge, we found that multiple studies showed decreases in ability to stop life-threatening bleeding when retested weeks or months after training. These issues of retention and a lack of education in general lead to a discussion about the possible benefits of having just-in-time (JiT) information during a bleeding emergency.

Summary

Based on the recent findings, bleeding control trainings have proven to be a very effective method of providing the general public with necessary skills. Therefore, moving forward, it is crucial to look at retention and the use of JiT information in longitudinal studies.

Cost-Efficient Medical Education: An Innovative Approach to Creating Educational Products

BACKGROUND

Cost is a barrier to creating educational resources, and new educational initiatives are often limited in distribution. Medical training programs must develop strategies to create and implement cost-effective educational programming.

OBJECTIVE

We developed high-quality medical programming in procedural instruction with efficient economics, reaching the most trainees at the lowest cost.

METHODS

The Just-In-Time online procedural program was developed at the University of Toronto in Canada, aiming to teach thoracentesis, paracentesis, and lumbar puncture skills to internal medicine trainees. Commercial vendors quoted between CAD $50,000 and $100,000 to create 3 comprehensive e-learning procedural modules-a cost that was prohibitive. Modules were therefore developed internally, utilizing 4 principles aimed at decreasing costs while creating efficiencies: targeting talent, finding value abroad, open source expansion, and extrapolating efficiency.

RESULTS

Procedural modules for thoracentesis, paracentesis, and lumbar puncture were created for a total cost of CAD $1,200, less than 3% of the anticipated cost in utilizing traditional commercial vendors. From November 2016 until October 2018, 1800 online instructional sessions have occurred, with over 3600 pageviews of content utilized. While half of the instructional sessions occurred within the city of Toronto, utilization was documented in 10 other cities across Canada.

CONCLUSIONS

The Just-in-Time online instructional program successfully created 3 procedural modules at a fraction of the anticipated cost and appeared acceptable to residents based on website utilization.

National Stop the Bleed Day: The impact of a social media campaign on the Stop the Bleed program

BACKGROUND

National Stop the Bleed Day (NSTBD) was created to increase public awareness of the official Stop-the-Bleed initiative and the Bleeding Control Basic course. The goal was to develop and employ an effective national social media strategy that would encourage and support efforts already in place to train the public in basic bleeding control techniques.

METHODS

March 31, 2018, was designated as NSTBD. Analysis focused on a 2-week window centered on NSTBD. The number of courses offered, number of instructors registered and total number of students trained overall during this period was derived from the American College of Surgeons (ACS) website bleedingcontrol.org. Courses not registered with the ACS were not included. Data on overall website activity were also included for analysis.

RESULTS

Forty-three states and 18 countries participated in NSTBD. During the study period, there were 1884 courses registered on bleedingcontrol.org. Comparatively, over a 4-month period from August to November 2017, the mean number of registered courses per month was 834. There were 34,699 students trained during the two-week study period as opposed to August to November 2017, the mean number of people trained per month was 9,626. In addition, 576 new B-Con instructors were certified during this time window. Additionally, the international coordinators reported 1500 students were trained during the study period. During this time, the ACS reported a significant increase in website activity. This included 10,530 new visitors, 12,772 visitors overall and 35,342 page views recorded during the study period.

CONCLUSION

The NSTBD effort was successful in generating widespread interest for the Stop-the-Bleed initiative. The use of a targeted social media campaign in this context was successful in driving people to available training opportunities while also increasing awareness of the overall effort. While only in its early stages, the NSTBD concept is a good one and should be developed further in coming years.

From the battlefield to main street: Tourniquet acceptance, use, and translation from the military to civilian settings

Throughout history, battlefield medicine has led to advancements in civilian trauma care. In the most recent conflicts of Operation Enduring Freedom in Afghanistan/Operation Iraqi Freedom, one of the most important advances is increasing use of point-of-injury hemorrhage control with tourniquets. Tourniquets are gradually gaining acceptance in the civilian medical world-in both the prehospital setting and trauma centers. An analysis of Emergency Medical Services (EMS) data shows an increase of prehospital tourniquet utilization from 0 to nearly 4,000 between 2008 and 2016. Additionally, bystander educational campaigns such as the Stop the Bleed program is expanding, now with over 125,000 trained on tourniquet placement. Because the medical community and the population at large has broader acceptance and training on the use of tourniquets, there is greater potential for saving lives from preventable hemorrhagic deaths.

Can they stop the bleed? Evaluation of tourniquet application by individuals with varying levels of prior self-reported training

BACKGROUND

Application of extremity tourniquets is a central tenet of multiple national initiatives to empower laypersons to provide hemorrhage control (HC). However, the efficacy of the general population who self-report prior first-aid (FA) or HC training on individual's ability to control bleeding with a tourniquet remains unknown. Therefore, the objective of this study was to assess the effectiveness of laypeople with self-reported prior FA or HC training to control bleeding with a tourniquet.

STUDY DESIGN

Employees of a stadium were assessed via simulation in their ability to apply a Combat Application Tourniquet. As a subgroup analysis of a larger study, participants who self-reported: 1) No prior training, 2) FA training only or 2) FA + HC training were compared. Logistic regression adjusting for age, gender, education, willingness-to-assist, and comfort level in HC was performed.

RESULTS

317 participants were included. Compared to participants with no prior training (14.4%,n = 16/111), those with FA training only (25.2%,n = 35/139) had a 2.12-higher odds (95%CI:1.07-4.18) of correct tourniquet application while those with FA + HC (35.8%,n = 24/67) had a 3.50-higher odds (95%CI:1.59-7.72) of correct application. Participants with prior FA + HC were more willing-to-assist and comfortable performing HC than those without prior training (p < 0.05). However, reporting being very willing-to-assist [OR0.83,95%CI:0.43-1.60] or very comfortable [OR1.11,95%CI:0.55-2.25] was not associated with correct tourniquet application.

CONCLUSION

Self-reported prior FA + HC training, while associated with increased likelihood to correctly apply a tourniquet, results in only 1/3 of individuals correctly performing the skill. As work continues in empowering and training laypeople to act as immediate responders, these findings highlight the importance of effective layperson education techniques.

Equipping Public Spaces to Facilitate Rapid Point-of-Injury Hemorrhage Control After Mass Casualty

In response to increasing violent attacks, the Stop the Bleed campaign recommends that everyone have access to both personal and public bleeding-control kits. There are currently no guidelines about how many bleeding victims public sites should be equipped to treat during a mass casualty incident. We conducted a retrospective review of intentional mass casualty incidents, including shootings, stabbings, vehicle attacks, and bombings, to determine the typical number of people who might benefit from immediate hemorrhage control by a bystander before professional medical help arrives. On the basis of our analysis, we recommend that planners at public venues consider equipping their sites with supplies to treat a minimum of 20 bleeding victims during an intentional mass casualty incident.

Building community resilience: A scalable model for hemorrhage-control training at a mass gathering site, using the RE-AIM framework

BACKGROUND

In a decade, the US military reduced deaths from uncontrolled bleeding on the battlefield by 67%. This success, coupled with an increased incidence of mass shootings in the US, has led to multiple initiatives intent on translating hemorrhage-control readiness to the civilian sector. However, the best method to achieve widespread population-level hemorrhage-control readiness for civilians has not yet been elucidated. This study evaluates the implementation of American College of Surgeons Bleeding Control training at a National Football League stadium as a prospective model for general mass gathering site implementation.

METHODS

The American College of Surgeons' Bleeding Control Basic layperson hemorrhage-control training was implemented at Gillette Stadium in Massachusetts. The five domains are as follows: reach (demographics of study participants), effectiveness (correct tourniquet application after intervention), adoption (investigator, leadership, and participant efforts for sustainability of intervention), implementation (course details), and maintenance (correct tourniquet application at retention testing at 3 to 9 months).

RESULTS

A total of 562 employees were included in the study. Of those included employees, 58.7% reported having taken first-aid training and 17.3% reported having taken hemorrhage-control training. There was an increased mean likelihood to help (4.39 vs 4.09, P < .01) and comfort level to control hemorrhage (4.26 vs 3.60, P < .01) after training compared with before training, on a Likert scale (1-5). The stadium operations team located hemorrhage control kits with automatic external defibrillators, integrated layperson immediate-response awareness into its Web site, and developed a public safety announcement. The training, performed by physicians, nurses, and emergency medical technicians, consisted of a 30-minute lecture and a 30-minute hands-on skills-training course, with a class size of 24. The total number of sessions was 24.

CONCLUSION

Achieving initial hemorrhage-control readiness and maintenance at a mass gathering site through American College of Surgeons Bleeding Control training is feasible but requires significant commitment from training staff, site leadership, and financial resources.
