Recommendations for Improving Stop the Bleed: A Systematic Review
Nichols R, Horstman J
Military medicine. 2022
Abstract
INTRODUCTION In response to mass casualty events, The Hartford Consensus brought together subject matter experts across multiple disciplines in health care and public safety to create guidelines and publications intended to improve survivability in active shooter events. Among the recommendations was the earlier recognition and treatment application of life-threatening hemorrhage control. These recommendations culminated in efforts to create the Stop the Bleed Campaign, which aims to empower the layperson to render aid in a life-threatening bleeding emergency. As of February 2020, the program has held over 86,000 courses, trained over 1.4 million attendees, and over 77,000 instructors since its inception. In addition to spreading within the United States, American College of Surgeons (ACS) Stop the Bleed (StB) classes have been held in 118 different countries. This systematic narrative review aims to answer the following research question: What does the ACS StB Initiative do well, and where can it improve? MATERIALS AND METHODS The following search terms were utilized: "Stop the Bleed," "American College of Surgeons," "bleeding control," "first-aid," tourniquet, "wound pack," "direct pressure" hemorrhage, and bystander. The inclusion criteria were that the article needed to speak to the program or some aspect of bystander first aid, the article needed to be in a civilian setting, the article needed to be more than a case study or overview, and the first aid tools needed to be in the StB curriculum. 4 databases were searched, which produced 138 articles for screening. One hundred four full-text articles were able to be retrieved, and 56 articles were determined to meet the inclusion criteria once the full text was reviewed. RESULTS Fifty-six articles were included in the final review and were placed into the following categories: Needs Within the Community, Confidence and Knowledge, Training Modalities, Barriers and Gaps in Training, Instructor Selection, Skill Retention, and Patient Outcomes. The articles were then organized into each outcome for synthesis and reporting of the results. The program overwhelmingly improves short-term confidence, but gaps in skill retention, data collection on patient outcomes, and settings that would benefit were identified. CONCLUSION StB is an effective tool in building confidence in laypersons, which is its biggest strength. A review of the literature shows several areas where the curriculum and materials could be better developed. Research can also be further refined to better quantify the program's impact.

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

Journal of surgical education. 2022
Abstract
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 use of trauma transfusion pathways for blood component transfusion in the civilian population: a systematic review and meta-analysis

Transfusion Medicine. 2012;22((3):):156-66.
Abstract
This study was undertaken to determine if, amongst civilian trauma patients requiring massive transfusion (MT), the use of a formal trauma transfusion pathway (TTP), in comparison with transfusion without a TTP, is associated with a reduction in mortality, or changes in indices of coagulation, blood product utilisation and complications. A systematic review of three bibliographic databases, reference lists and conference proceedings was conducted. Studies were included if comparisons were made between patients receiving transfusion with and without a TTP. Data were extracted by two independent reviewers on population characteristics, transfusion strategies, blood product utilisation, indices of coagulation, clinical outcomes and complications. Data were pooled using a random effects model and heterogeneity explored. Seven observational studies met all eligibility criteria. Amongst 1801 patients requiring MT, TTPs were associated with a significant reduction in mortality (RR 0.69, 95% CI 0.55, 0.87). No significant increase in the mean number of PRBC transfused between TTP and control patients was seen (MD -1.17 95% CI -2.70, 0.36). When studies assessing only trauma patients were considered, TTPs were associated with a reduction in the mean number of units of plasma transfused (MD -2.63, 95% CI -4.24, -1.01). In summary, the use of TTPs appears to be associated with a reduction in mortality amongst trauma patients requiring MT without a clinically significant increase in the number of PRBC transfused and a potential reduction in plasma transfusion. Effects of TTPs on platelet transfusion, indices of coagulation and complications remain unclear. A randomised controlled trial is warranted. Copyright 2012 The Authors.

Transfusion. 2012;52((12):):2692-705.
Abstract
BACKGROUND Critically bleeding trauma patients require coordinated and efficient decision-making processes to ensure optimal management of their massive transfusion (MT) requirements. Human factors (HFs) is a discipline that investigates factors influencing work processes from the organizational, group, and individual levels. Given the complexity of trauma resuscitation, implementing any intervention for decision support in MT is challenging and may benefit from a HFs-assisted approach. STUDY DESIGN AND METHODS A systematic review was performed to identify reports of the introduction of any type of decision support for the provision of MT in critically bleeding adult trauma patients. Crucial contributions reported to influence design and uptake of the intervention were categorized into four HFs categories (environment, human, machine, and task). Extracted information was supplemented by surveying the contact authors. Evidence of clinical practice changes resulting from the intervention was also considered. RESULTS We identified nine studies that had reported an intervention implementing new practice guidelines or a MT protocol. All were before-and-after comparative cohort studies and used historical controls as the preintervention cohort. CONCLUSION Based on the identified reports, this review provides a HFs-assisted approach to aid clinicians and policy makers with the implementation of decision support for MT in the trauma care setting.
