Background: Massive transfusion protocols (MTP) are widely used to rapidly deliver blood products to bleeding trauma patients. Every minute delay in blood product administration in bleeding trauma patients is associated with a 5% increased odds of death. In-situ simulation (ISS) is simulation that takes place in the actual clinical work environment. We used ISS as a novel, prospective and iterative quality improvement (QI) approach to identify and improve MTP steps that impact time to blood delivery (TTBD) during actual trauma resuscitations. Aim Statement: To reduce the TTBD for bleeding trauma patients by 20% over a 12-month ISS-based QI initiative. Measures & Design: We conducted twelve high-fidelity, interprofessional ISS sessions at a Level-1 trauma center in Toronto, Canada. We used clinician video review as well as extensive stakeholder involvement, including with nurses, porters, blood bank and human factors experts, to develop Plan-Do-Study-Act (PDSA) cycles for MTP improvement. Our three major PDSA cycles revolved around: 1) decreasing MTP activation time; 2) reducing the unpredictable and inefficient transport times for the blood itself; and 3) improving the notification of blood product arrival in the trauma bay. Each PDSA cycle was iteratively tested with ISS prior to implementation into clinical care. Outcome measure was the mean TTBD for trauma patients requiring MTP (in minutes, standard deviation [SD]). Process measures included time to MTP activation and porter transport times. Balancing measures included stakeholder satisfaction. Evaluation/Results: Our baseline TTBD for MTP patients was 11.58min (n = 41, SD 6.8). There were 54 trauma patients that had MTP during the ISS-based QI initiative, and their mean TTBD was 10.44min (SD 6.1). The TTBD after the QI initiative was 9.12min, sustained over 1 year (n = 50, SD 5.3; 21.2% relative reduction, p < 0.05). A run chart did not show special cause variation chronologically related to our interventions. Patients in each group were similar in demographic data, trauma characteristics and injury severity score. Discussion/Impact: We achieved a 21.2% reduction in TTBD for trauma patients requiring MTP with an ISS-based QI initiative. ISS represents a novel approach to the identification and iterative testing of process improvements within trauma care. This methodology can and should be included in QI projects in order to safely test and improve processes of care before they impact real patients.

Noncompressible torso injuries (NCTIs) represent a trauma-related condition with high lethality. This study’s aim was to identify potential prediction factors of mortality in this group of trauma patients at a Level 1 trauma center in Italy. Materials and Methods: A total of 777 patients who had sustained a noncompressible torso injury (NCTI) and were admitted to the Niguarda Trauma Center in Milan from 2010 to 2019 were included. Of these, 166 patients with a systolic blood pressure (SBP) <90 mmHg were considered to have a noncompressible torso hemorrhage (NCTH). Demographic data, mechanism of trauma, pre-hospital and in-hospital clinical conditions, diagnostic/therapeutic procedures, and survival outcome were retrospectively recorded. Results: Among the 777 patients, 69% were male and 90.2% sustained a blunt trauma with a median age of 43 years. The comparison between survivors and non-survivors pointed out a significantly lower pre-hospital Glasgow coma scale (GCS) and SBP (p < 0.001) in the latter group. The multivariate backward regression model identified age, pre-hospital GCS and injury severity score (ISS) (p < 0.001), pre-hospital SBP (p = 0.03), emergency department SBP (p = 0.039), performance of torso contrast enhanced computed tomography (CeCT) (p = 0.029), and base excess (BE) (p = 0.008) as independent predictors of mortality. Conclusions: Torso trauma patients who were hemodynamically unstable in both pre- and in-hospital phases with impaired GCS and BE had a greater risk of death. The detection of independent predictors of mortality allows for the timely identification of a subgroup of patients whose chances of survival are reduced.

Innovation Concept: Effective communication for ad hoc teams is critical to successful management of multisystem trauma patients, to improve situational awareness and to mitigate risk of error. OBJECTIVES 1. Improve communication of ad hoc teams. 2. Identify system gaps. INNOVATION Team in situ simulations provide a unique opportunity to practice communication and assess systems in the real environment. Our trauma team consists of residents and staff from emergency services, general surgery, orthopedics, anaesthesia, nursing and respiratory therapy. Methods: A team of subject matter experts (SME's) from trauma, nursing, emergency medicine and simulation co-developed curriculum in response to a needs assessment that identified gaps in systems and team communication. The simulation occurred in the actual trauma bay. The on-call trauma team was paged and expected to manage a simulated multisystem trauma patient. Once the team arrived, they participated in a briefing, manikin-based simulation and a communication and system focused debriefing. Curriculum, Tool, or Material: Monthly scenarios consisted of management of a blunt trauma patient, emergency airway and massive hemorrhage protocol. Teams were assessed on communication skills and timeliness of interventions. Debriefing consisted of identification of system gaps and latent safety threats. Feedback was given by each discipline followed by SME's. Information was gathered from participant evaluations (5-point Likert scale and open ended questions) and group debrief. Feedback was themed and actions taken to co-create interventions to communication gaps and latent safety threats. As a result, cricothyroidotomy trays were standardized throughout the hospital to mitigate confusion, time delay and unfamiliarity during difficult airway interventions. Participants felt the exercise was an effective means of practicing interprofessional communication and role clarity, and improved their attitude towards the same. Conclusion: In situ simulation-based education with ad hoc trauma teams can improve interprofessional communication and identify latent safety threats for the management of multisystem trauma patients.

Introduction: The anticoagulated trauma patient is a particularly vulnerable population. Our current practice is guided by experience with patients taking vitamin K dependent antagonists (VKA, like warfarin). It is currently unknown how the increasing use of direct oral anticoagulants (DOACs) will change our trauma population. We collected data about this new subset of patients to compare their clinical characteristics to patients on pre-injury VKA therapy. Methods: Retrospective review of anticoagulated trauma patients presenting to Toronto’s two adult trauma centres, Saint Michael’s Hospital and Sunnybrook Health Sciences Centre, from June 2014-June 2015 was undertaken. Patients were recruited through the institutions’ trauma registries and were eligible if they suffered a traumatic injury and taking an oral anticoagulant pre-injury. Clinical and demographic data were extracted by a trained reviewer and analysed with descriptive statistics. Results: Our study recruited 85 patients, 33% were taking DOACs and 67% VKAs. Trauma patients on DOACs & VKAs respectively had similar baseline characteristics such as age (75.9 vs 77.4), initial injury severity score (ISS (16.9 vs 20.6)) and concomitant antiplatelet use (7.1% vs 5.4%). Both groups’ most common mechanism for injury was falls and the most common indication for anticoagulation was atrial fibrillation. Patients on DOACs tended to have lower average INR (1.25 vs 2.3) and serum creatinine (94.9 vs 127.4). Conclusion: Patients on DOACs pre-injury now account for a significant proportion of orally anticoagulated trauma patients. Patients on DOACs tended to have less derangement of basic hematological parameters complicating diagnosis and management of coagulopathy.

Abstract Backgrounds The COVID-19 pandemic drastically strained the health systems worldwide, obligating the reassessment of how healthcare is delivered. In Lombardia, Italy, a Regional Emergency Committee (REC) was established and the regional health system reorganized, with only three hospitals designated as hubs for trauma care. The aim of this study was to evaluate the effects of this reorganization of regional care, comparing the distribution of patients before and during the COVID-19 outbreak and to describe changes in the epidemiology of severe trauma among the two periods. Methods A cohort study was conducted using retrospectively collected data from the Regional Trauma Registry of Lombardia (LTR). We compared the data of trauma patients admitted to three hub hospitals before the COVID-19 outbreak (September 1 to November 19, 2019) with those recorded during the pandemic (February 21 to May 10, 2020) in the same hospitals. Demographic data, level of pre-hospital care (Advanced Life Support-ALS, Basic Life Support-BLS), type of transportation, mechanism of injury (MOI), abbreviated injury score (AIS, 1998 version), injury severity score (ISS), revised trauma score (RTS), and ICU admission and survival outcome of all the patients admitted to the three trauma centers designed as hubs, were reviewed. Screening for COVID-19 was performed with nasopharyngeal swabs, chest ultrasound, and/or computed tomography. Results During the COVID-19 pandemic, trauma patients admitted to the hubs increased (46.4% vs 28.3%, p < 0.001) with an increase in pre-hospital time (71.8 vs 61.3 min, p < 0.01), while observed in hospital mortality was unaffected. TRISS, ISS, AIS, and ICU admission were similar in both periods. During the COVID-19 outbreak, we observed substantial changes in MOI of severe trauma patients admitted to three hubs, with increases of unintentional (31.9% vs 18.5%, p < 0.05) and intentional falls (8.4% vs 1.2%, p < 0.05), whereas the pandemic restrictions reduced road- related injuries (35.6% vs 60%, p < 0.05). Deaths on scene were significantly increased (17.7% vs 6.8%, p < 0.001). Conclusions The COVID-19 outbreak affected the epidemiology of severe trauma patients. An increase in trauma patient admissions to a few designated facilities with high level of care obtained satisfactory results, while COVID-19 patients overwhelmed resources of most other hospitals.

Abstract Background: Trauma patients often require massive transfusion and their resuscitation is commonly complicated by coagulopathy. Debate persists regarding optimal massive transfusion strategies, which have traditionally adopted 2 approaches: coagulation laboratory based therapy (LBT) versus fixed ratio trauma transfusion pathways (TTP). The proponents of a LBT strategy cite “rational use” and avoidance of over-transfusion. This system may not adequately address the dynamic trauma situation where a delay in coagulation results may be detrimental. A TTP more rapidly meets the needs of trauma patients but may increase blood product utilization. Objective: Retrospectively compare our preliminary early experience with a TTP compared to our previous LBT strategy. Method: Retrospective cohort study using our transfusion database comparing 14 patients who activated the TTP with 28 patients treated before the pathways introduction. Inclusion criteria included severe traumatic injury (Injury Severity Score (ISS) &gt;12), massive transfusion (defined as &gt;8 units of red blood cells (RBCs) in the first 24 hours). The TTP is activated by the trauma team and results in the immediate release of 4 units of uncrossmatched RBCs. Blood product is then issued in trauma packs (TPs). Each trauma pack contains 4 units of RBCs and 4 units of frozen plasma (FP) and every second pack contains one pool of platelets (PLTs). A dose of recombinant factor VIIa (rFVIIa) is made available after TP #3. Cryoprecipitate (CRYO) is issued only at the request of the trauma team. A CBC, INR, PTT, and fibrinogen is measured at TTP activation and after every other TP. Outcomes: Outcome variables included total blood product utilization (RBC, FP, CRYO, PLTs), time to first and second set of FP (time 0 is release of 1st RBC unit), number of RBC units issued until first and second set of FP, coagulopathy at presentation and highest INR during first 24 hours of resuscitation. Results: The results are summarized in the attached table. There was no difference in ISS between groups. The introduction of the TTP resulted in no difference in the amount of blood product utilization when compared to the pre-pathway control group. Significant differences included a much shorter time to first and second FP delivery and fewer RBC units before the first and second FP delivery. The majority of the patients were coagulopathic on presentation (defined as INR &gt; 1.4) and the TTP group achieved a significantly lower peak INR during the first 24 hours of resuscitation compared to the pre-pathway group. Conclusion: This pilot study shows that the introduction of a trauma transfusion pathway significantly improves coagulopathy and reduces time to FP administration without increasing blood product utilization.

Abstract Introduction Safe and effective management of trauma patients requires numerous practical skills. Our in-situ trauma simulation identified key areas requiring increased training and exposure. This enabled improvement to education, patient safety and efficiency when managing these emergencies. Method We carried out a simulated trauma call according to ATLS principles, recording the time and person completing each task. Key areas for improvement were identified; most notably the application of Femoral Traction Splints (FTS). 0/7 doctors present were not able to do this. Subsequently, a formal training day was delivered, with 38 attendees across specialties, assessing confidence before and after the session. Results Prior to the training session, 52.6% of attendees did not have formal teaching using FTS and 65.8% had never used one. Confidence with FTS application was measured on a scale of 1 (not confident) to 5 (very confident), with an average score of 2.6/5. After training, the average confidence score was 4.7/5 (p &lt; 0.01). 100% of participants found the session very useful. Conclusions In-situ simulation allows identification of key areas for improvement in training of practical skills. Essential tailored teaching can then be delivered to increase exposure and confidence for these necessary practical skills.

ObjectivesTo describe the association between participant profession and the number and type of latent safety threats (LSTs) identified during in situ simulation (ISS). Secondary objectives were to describe the association between both (a) participants’ years of experience and LST identification and (b) type of scenario and number of identified LSTs.MethodsEmergency staff physicians (MDs), registered nurses (RNs) and respiratory therapists (RTs) participated in ISS sessions in the emergency department (ED) of a tertiary care teaching hospital. Adult and paediatric scenarios were designed to be high-acuity, low-occurrence resuscitation cases. Simulations were 10 min in duration. A written survey was administered to participants immediately postsimulation, collecting demographic data and perceived LSTs. Survey data was collated and LSTs were grouped using a previously described framework.ResultsThirteen simulation sessions were completed from July to November 2018, with 59 participants (12 MDs, 41 RNs, 6 RTs). Twenty-four unique LSTs were identified from survey data. RNs identified a median of 2 (IQR 1, 2.5) LSTs, significantly more than RTs (0.5 (IQR 0, 1.25), p=0.04). Within respective professions, MDs and RTs most commonly identified equipment issues, and RNs most commonly identified medication issues. Participants with ≤10 years of experience identified a median of 2 (IQR 1, 3) LSTs versus 1 (IQR 1, 2) LST in those with >10 years of experience (p=0.06). Adult and paediatric patient scenarios were associated with the identification of a median of 4 (IQR 3.0, 4.0) and 5 LSTs (IQR 3.5, 6.5), respectively (p=0.15).ConclusionsInclusion of a multidisciplinary team is important during ISS in order to gain a breadth of perspectives for the identification of LSTs. In our study, participants with ≤10 years of experience and simulations with paediatric scenarios were associated with a higher number of identified LSTs; however, the difference was not statistically significant.

Transfusion Protocol

Background: In massive bleeding trauma patients, the use of massive transfusion protocol (MTP) has been shown to improve the outcome. However, the triggers for MTP activation vary among institutions. One of the most commonly used scoring systems to predict massive transfusion (MT) is the assessment of blood consumption (ABC) score. The authors’ institution has used a simple clinical criterion, the Class-4 Hemorrhage Unresponsive to Lactated Ringer’s (CHULA criteria), as a trigger for MTP activation. Objective: To identify the accuracy of CHULA criteria for MTP activation in trauma patients. Materials and Methods: Between April 2013 and April 2016, the authors retrospectively collected the data of trauma patients receiving blood transfusion in the first 24 hours at King Chulalongkorn Memorial Hospital, including demographic data, trauma scores, amount of blood transfusion, and mortality. The detail of CHULA criteria included 1) a patient with clinical signs of Class-4 hemorrhage, 2) not responding to one to two liters of Lactated Ringer’s bolus, and 3) had suspected ongoing bleeding. MT was defined as 1) packed red blood cells (PRC) transfusion of equal to or greater than 10 units in 24 hours, or 2) PRC transfusion of more than four units in the first hour. The accuracy of CHULA criteria for MTP activation was analyzed. Comparison between CHULA criteria and ABC score (of equal to or greater than 2) was also performed. Results: Three hundred fifty-eight patients were included in the present study, 292 males and 66 females. The mechanisms of injury were 68% blunt and 32% penetrating, with an average injury severity score of 21. MTP was activated by CHULA criteria in 100 patients and 73 received MT. Of the 258 patients who did not meet CHULA criteria, five received MT. As a trigger for MT activation, CHULA criteria had sensitivity, specificity, and accuracy of 93.6%, 90.4%, and 91%, respectively; while ABC score had sensitivity, specificity, and accuracy of 62.8%, 78.9%, and 75.4%, respectively. Conclusion: CHULA criteria can predict MT in trauma patients with 91% accuracy. When compared with ABC score, CHULA criteria were not inferior to ABC score in predicting MT.

This study aims to examine resource utilization and outcomes of trauma patients with extremely high blood alcohol concentrations. We hypothesized that higher blood alcohol concentration (BAC) predicts greater resource utilization and poorer outcomes. A retrospective analysis was performed on trauma patients admitted to an urban Level I trauma center over a 5-year period. Admission BAC categories were constructed using standard laboratory norms and legal definitions. Demographic data, premorbid conditions, injury severity scores (ISS), resource utilization (intensive care unit (ICU) admission rates/length of stay, total hospital days, use of consultants), and mortality were analyzed. Positive BAC on admission was associated with increased ISS ( P < 0.001), length of stay ( P < 0.003), and total ICU days ( P < 0.001). Increased BAC admission level of patients was associated with a decreased ISS score ( P = 0.0073), a higher probability of ICU admission ( P = 0.0013), and an increased percentage of ICU days ( P = 0.001). A positive BAC at admission was a significant predictor of both ICU admission and mortality (odds ratios 1.72 and 1.27, respectively). This study demonstrates that a positive BAC is associated with increased ISS, increased resource utilization, and worsened outcomes. Extreme levels of BAC are associated with increased resource utilization despite lower injury severity scores.
