Abstract
INTRODUCTION Nursing knowledge, critical thinking ability, and self-perceived confidence are imperative to nursing skills in professional nursing practice. Therefore, nurse educators are required to use teaching strategies that will help promote their knowledge, critical thinking, and self-confidence in complex contents such as the nursing of acute upper gastrointestinal bleeding (AUGIB). PURPOSE This study compares the effect of student-led and instructor-led ward-round training methods on knowledge acquisition, critical thinking ability, and self-perceived confidence during AUGIB sessions. METHODS Forty nursing students in the first year of the Emergency Nursing Residency Program were randomly divided into a student-led ward round training group (SG) and an instructor-led ward round training group (IG) with a ratio of 1:1. A knowledge quiz, critical thinking ability test, and self-perceived confidence questionnaire were performed before and after the ward round training to assess both groups of students for their knowledge acquisition, critical thinking ability, and self-perceived confidence improvement. Feedback questionnaires were conducted after the training to evaluate students' perspectives and interests concerning the teaching module. RESULTS The scores of the post-training quiz were significantly higher than that of the pre-training quiz in both the SG (44.10±2.92 vs 31.10±4.27, p<0.001) and IG (32.35±2.21 vs 30.55±2.24, p=0.01). In the post-training quiz, scores achieved by the students from the SG (44.10±2.92) were significantly higher than those achieved by the students from the IG (32.35±2.21, p< 0.001). The level of self-perceived confidence improved significantly after ward round training in the SG (p< 0.001). However, there was no statistically significant difference in the IG with respect to the change from pre- to post-training (p=0.43).The students' critical thinking ability improved significantly in the SG (14.95±2.58 vs 7.10±1.79, p<0.001), while no significant improvement was found in the IG (7.91±2.28 vs 6.52±2.21, p=0.07) after ward round training. CONCLUSION The teaching method of SWRT improves nursing students' knowledge acquisition, critical thinking ability, and self-perceived confidence in AUGIB.

Abstract
BACKGROUND The "Stop the Bleed" (STB) campaign has achieved remarkable results since it was launched in 2016, but there is no report on the teaching of an STB course combined with a trauma patient simulator. This study proposes the "problem-, team-, and evidence-based learning" (PTEBL) teaching method combined with Caesar (a trauma patient simulator) based on the STB course and compares its effect to that of the traditional teaching method among outstanding doctoral candidates training in haemostasis skills. METHOD Seventy-eight outstanding doctoral candidate program students in five and eight-year programs were selected as the research subjects and were randomly divided into a control group (traditional teaching method, n = 34) and an experimental group (PTEBL teaching method combined with Caesar, n = 44). Their confidence in their haemostasis skills and willingness to rescue injured victims were investigated before and after the course in both groups. RESULT Students' self-confidence in their STB skills and the willingness to rescue improved after the class in both groups. Compared with the control group, students in the experimental group were more confident in compressing with bandages and compressing with a tourniquet after a class (compressing with bandages: control group 3.9 ± 0.8 vs. experimental group 4.3 ± 0.7, P = 0.014; compressing with a tourniquet: control group 3.9 ± 0.4 vs. experimental group 4.5 ± 0.8, P = 0.001) More students in the experimental group than the control group thought that the use of Caesar for scenario simulation could improve learning (control group 55.9% vs. experimental group 81.8%, P = 0.024), and using this mannequin led to higher teacher-student interaction (control group 85.3% vs. experimental group 97.7%, P = 0.042). The overall effectiveness of the teaching was better in the experimental group than in the control group (control group 85.3% vs. experimental group 97.7%, P = 0.042). There was a significant positive correlation between teacher-student interactions and the overall effectiveness of teaching (R = 1.000; 95% CI, 1.000-1.000; P < 0.001). CONCLUSION The PTEBL teaching method combined with Caesar can effectively improve student mastery of STB skills and overcome the shortcomings of traditional teaching methods, which has some promotional value in the training of outstanding doctoral candidates in STB skills.

Journal of osteopathic medicine. 2021
Abstract
CONTEXT Some medical schools integrate STOP THE BLEED(®) training into their curricula to teach students how to identify and stop life threatening bleeds; these classes that are taught as single day didactic and hands-on training sessions without posttraining reviews. To improve retention and confidence in hemorrhage control, additional review opportunities are necessary. OBJECTIVES To investigate whether intermittent STOP THE BLEED(®) reviews were effective for long term retention of hemorrhage control skills and improving perceived confidence. METHODS First year osteopathic medical students were asked to complete an eight item survey (five Likert scale and three quiz format questions) before (pretraining) and after (posttraining) completing a STOP THE BLEED(®) training session. After the surveys were collected, students were randomly assigned to one of two study groups. Over a 12 week intervention period, each group watched a 4 min STOP THE BLEED(®) review video (intervention group) or a "distractor" video (control group) at 4 week intervals. After the 12 weeks, the students were asked to complete an 11 item survey. RESULTS Scores on the posttraining survey were higher than the pretraining survey. The median score on the five Likert scale items was 23 points for the posttraining survey and 14 points for the pretraining survey. Two of the three knowledge based quiz format questions significantly improved from pretraining to posttraining (both p<0.001). On the 11 item postintervention survey, both groups performed similarly on the three quiz questions (all p>0.18), but the intervention group had much higher scores on the Likert scale items than the control group regarding their confidence in their ability to identify and control bleeding (intervention group median = 21.4 points vs. control group median = 16.8 points). CONCLUSIONS Intermittent review videos for STOP THE BLEED(®) training improved medical students' confidence in their hemorrhage control skills, but the videos did not improve their ability to correctly answer quiz-format questions compared with the control group.

Abstract
BACKGROUND The mortality of trauma patients requiring massive transfusion to treat hemorrhagic shock approaches 17% at 24 hours and 26% at 30 days. The use of stored RBCs is limited to less than 42 days, so older RBCs are delivered first to rapidly bleeding trauma patients. Patients who receive a greater quantity of older RBCs may have a higher risk for mortality. METHODS AND MATERIALS Characterizing blood age exposure requires accounting for the age of each RBC unit and the quantity of transfused units. To address this challenge, a novel Scalar Age of Blood Index (SBI) that represents the relative distribution of RBCs received is introduced and applied to a secondary analysis of the Pragmatic, Randomized Optimal Platelet and Plasma Ratios (PROPPR) randomized controlled trial (NCT01545232, https://clinicaltrials.gov/ct2/show/NCT01545232). The effect of the SBI is assessed on the primary PROPPR outcome, 24-hour and 30-day mortality. RESULTS The distributions of blood storage ages successfully maps to a parameter (SBI) that fully defines the blood age curve for each patient. SBI was a significant predictor of 24-hour and 30-day mortality in an adjusted model that had strong predictive ability (odds ratio, 1.15 [1.01-1.29], p = 0.029, C-statistic, 0.81; odds ratio, 1.14 [1.02-1.28], p = 0.019, C-statistic, 0.88, respectively). CONCLUSION SBI is a simple scalar metric of blood age that accounts for the relative distribution of RBCs among age categories. Transfusion of older RBCs is associated with 24-hour and 30-day mortality, after adjustment for total units and clinical covariates.

Abstract
Importance: More than 500000 laypeople in the United States have been trained in hemorrhage control, including tourniquet application, under the Stop the Bleed campaign. However, it is unclear whether after hemorrhage control training participants become proficient in a specific type of tourniquet or can also use other tourniquets effectively. Objective: To assess whether participants completing the American College of Surgeons Bleeding Control Basic (B-Con) training with Combat Application Tourniquets (CATs) can effectively apply bleeding control principles using other tourniquet types (commercial and improvised). Design, Setting, and Participants: This nonblinded, crossover, sequential randomized clinical trial with internal control assessed a volunteer sample of laypeople who attended a B-Con course at Gillette Stadium and the Longwood Medical Area in Boston, Massachusetts, for correct application of each of 5 different tourniquet types immediately after B-Con training from April 4, 2018, to October 9, 2018. The order of application varied for each participant using randomly generated permutated blocks. Interventions: Full B-Con course, including cognitive and skill sessions, that taught bleeding care, wound pressure and packing, and CAT application. Main Outcomes and Measures: Correct tourniquet application (applied pressure of ≥250 mm Hg with a 2-minute time cap) in a simulated scenario for 3 commercial tourniquets (Special Operation Forces Tactical Tourniquet, Stretch-Wrap-and-Tuck Tourniquet, and Rapid Application Tourniquet System) and improvised tourniquet compared with correct CAT application as an internal control using 4 pairwise Bonferroni-corrected comparisons with the McNemar test. Results: A total of 102 participants (50 [49.0%] male; median [interquartile range] age, 37.5 [27.0-53.0] years) were included in the study. Participants correctly applied the CAT at a significantly higher rate (92.2%) than all other commercial tourniquet types (Special Operation Forces Tactical Tourniquet, 68.6%; Stretch-Wrap-and-Tuck Tourniquet, 11.8%; Rapid Application Tourniquet System, 11.8%) and the improvised tourniquet (32.4%) (P < .001 for each pairwise comparison). When comparing tourniquets applied correctly, all tourniquet types had higher estimated blood loss, had longer application time, and applied less pressure than the CAT. Conclusions and Relevance: The B-Con principles for correct CAT application are not fully translatable to other commercial or improvised tourniquet types. This study demonstrates a disconnect between the B-Con course and tourniquet designs available for bystander first aid, potentially stemming from the lack of consensus guidelines. These results suggest that current B-Con trainees may not be prepared to care for bleeding patients as tourniquet design evolves. Trial Registration: ClinicalTrials.gov identifier:NCT03538379.

Abstract
BACKGROUND Hemorrhage coupled with coagulopathy remains the leading cause of preventable in-hospital deaths among trauma patients. Use of a transfusion protocol with a predefined ratio of 1:1:1 (1 each of red blood cells [RBC], frozen plasma [FP] and platelets) has been associated with improved survival in retrospective studies in military and civilian settings, but such a protocol has its challenges and may increase the risk of respiratory complications. We conducted a randomized controlled trial to assess the feasibility of a 1:1:1 transfusion protocol and its effect on mortality and complications among patients with severe trauma. METHODS We included 78 patients seen in a tertiary trauma centre between July 2009 and October 2011 who had hypotension and bleeding and were expected to need massive transfusion (>= 10 RBC units in 24 h). We randomly assigned them to either the fixed-ratio (1:1:1) transfusion protocol (n = 40) or to a laboratory-results-guided transfusion protocol (control; n = 38). The primary outcome, feasibility, was assessed in terms of blood product ratios and plasma wastage. Safety was measured based on 28-day mortality and survival free of acute respiratory distress syndrome. RESULTS Overall, a transfusion ratio of 1:1:1 was achieved in 57% (21/37) of patients in the fixed-ratio group, as compared with 6% (2/32) in the control group. A ratio of 1:1 (RBC:FP) was achieved in 73% (27/37) in the fixed-ratio group and 22% (7/32) in the control group. Plasma wastage was higher with the intervention protocol (22% [86/390] of FP units v. 10% [30/289] in the control group). The 28-day mortality and number of days free of acute respiratory distress syndrome were statistically similar between the groups. INTERPRETATION The fixed-ratio transfusion protocol was feasible in our study, but it was associated with increased plasma wastage. Larger randomized trials are needed to evaluate the efficacy of such a protocol in trauma care. Trial registration: ClinicalTrials.gov, no. NCT00945542.
