Save-a-life at the ballpark: 10-min spectator training achieves proficiency in cardiac arrest response

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.

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.

Major League Soccer Provides a Captive Audience for Promoting Bystander CPR and AED Use Among Hispanics

OBJECTIVE

Rates of bystander cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use are lower in Hispanic compared to non-Hispanic white communities. Novel instructional methods that focus on population subgroups most likely to benefit must be explored. The purpose of this study was to determine the feasibility, efficiency, and participant demographics of 10-minute educational intervention on bystander CPR and AED use delivered at a pre-match festival for Major League Soccer (MLS) fans.

METHODS

Results are reported with descriptive statistics. The primary outcomes included: (1) Training efficiency index for cardiac arrest (TEICA) defined as persons trained/volunteer hours; (2) cardiac arrest training yield (CATY) defined as percent participation by the target audience; and (3) percent of participants of Hispanic origin. Our secondary outcome was average post intervention knowledge survey score.

RESULTS

CATY was 16% and TEICA was 3.81. Survey participation was 48.3% and 38.9% of survey participants were Hispanic. Average knowledge score post training was 87.5%.

CONCLUSION

Soccer matches may be a suitable setting for provision of CPR and AED training to Hispanics. This intervention gives insight into a novel way of providing health education to Hispanics that can be applied to other behaviors.

Irrational Exuberance: Cardiopulmonary Resuscitation as Fetish

The Institute of Medicine and the American Heart Association have issued a "call to action" to expand the performance of cardiopulmonary resuscitation (CPR) in response to out-of-hospital cardiac arrest. Widespread advertising campaigns have been created to encourage more members of the lay public to undergo training in the technique of closed-chest compression-only CPR, based upon extolling the virtues of rapid initiation of resuscitation, untempered by information about the often distressing outcomes, and hailing the "improved" results when nonprofessional bystanders are involved. We describe this misrepresentation of CPR as a highly effective treatment as the fetishization of this valuable, but often inappropriately used, therapy. We propose that the medical profession has an ethical duty to inform the public through education campaigns about the procedure's limitations in the out-of-hospital setting and the narrow clinical indications for which it has been demonstrated to have a reasonable probability of producing favorable outcomes.

Treatment and outcome of out-of-hospital cardiac arrest in outpatient health care facilities

AIM

We evaluated the frequency and effectiveness of basic and advanced life support (ALS) interventions by medical professionals when out-of-hospital cardiac arrest (OHCA) occurred in ambulatory healthcare clinics before emergency medical services (EMS) arrival.

METHODS

Non-traumatic OHCAs in adults were systematically characterized over a 15 year period by their occurrence in clinics, at home, or in non-medical public locations, and outcomes compared between matched cohorts from each group.

RESULTS

Among 7784 patients, 6098 OHCA occurred at home, 1612 in non-medical public locations and 74 in clinics. Compared to non-medical public locations, clinic patients with OHCA were older, more often women and more frequently shocked; clinic arrests were more often witnessed, less likely to be of cardiac cause and to occur before EMS arrival. Compared to home, more clinic arrests were witnessed, occurred after EMS arrival, had bystander CPR, shockable rhythms and were defibrillated. When OHCA occurred before EMS arrival, 51 of 56 clinic patients (91%) received CPR, a defibrillator applied to 23 (41%), 17 (30%) were shocked, 4 (7%) intubated, and 7 (13%) received intravenous medications from facility personnel. Of these, only pre-EMS defibrillator use was associated with improved outcome. Among matched patients, OHCA survival was higher in clinics than at home (42% vs 26%, p=0.029), but comparable to other public locations.

CONCLUSIONS

Survival from OHCA in clinics was comparable to non-medical public locations, and higher than at home. Alongside CPR, use of defibrillators was associated with improved survival and worth prioritizing over other interventions before EMS arrival regardless of OHCA location.
