Evaluating the impact of pre-hospital trauma team activation criteria.

Little evidence exists studying the benefits of pre-hospital trauma team activation. Our study measured the impact of pre-hospital trauma team activation on 24-h survival. Our secondary objectives assessed the effects of pre-hospital trauma team activation on time to emergency procedure, computed tomography, blood transfusion, and critical administration threshold, as well as emergency department length of stay. We conducted a 40-month health records review on all trauma team activations at The Ottawa Hospital, a Level 1 Trauma Center. Outcomes were compared between pre-hospital and in-hospital trauma team activations. We used logistic and linear regression models to assess outcomes, while controlling for injury severity score, age, systolic blood pressure, and anti-coagulation use. A P value < 0.05 was considered statistically significant. A sensitivity analysis was also used to validate the primary outcome results. Of the 1013 trauma team activations occurring during the study period, 762 patients were included. The mean age (41.3 vs. 43.8) and percentage of males (79.4% vs. 77.5%) for pre-hospital activations were similar to their counterparts. Pre-hospital activations did not have a statistically significant effect on 24-h mortality (14.4% vs. 4.5%; P = 0.30). However, pre-hospital activations did demonstrate a statistically significant reduction in time (minutes) to emergency procedure (18.0 vs. 27.0; P < 0.001), computed tomography (37.0 vs 42.0; P = 0.009), and blood transfusion (14.0 vs. 28.0; P < 0.001), as well as emergency department length of stay (101.0 vs. 171.0; P < 0.001). When controlling for key covariates, pre-hospital trauma team activation did not have a significant effect on 24-h mortality, but did result in a significant reduction in time to emergency procedure, computed tomography, and blood transfusion, as well as emergency department length of stay. Our study demonstrates that pre-hospital trauma team activation can expedite patient intervention and disposition.

The relationship between acute pain and other types of suffering in pre-hospital trauma victims: An observational study

BackgroundAcute pain is an important complaint reported by trauma victims, however, the relationship between it and other types of discomfort, such as discomfort caused by cold, discomfort caused by immobilization, and psychological distress such as fear, anxiety, and sadness is limitedly studied and documented. AimTo assess the relationship between acute trauma pain and other types of suffering in pre-hospital trauma victims. MethodsThis is a prospective multicentre cohort study conducted in Immediate Life Support Ambulances in Portugal. All adult trauma victims with a mechanism of blunt and penetrating injuries, falls, road accidents and explosions, were included. Results605 trauma victims were included, mainly male, with a mean age of 53.4 years. Before the intervention of the rescue teams, 90.5 % of the victims reported some level of pain, 39.0 % reported discomfort caused by cold, while 15.7 % felt fear, 8.4 % sadness, 49.8 % anxiety and 4.5 % apathy. Victims with high discomfort caused by cold tend to have higher pain levels. Significantly higher pain intensity were observed in victims with fear and anxiety. Univariate and multivariate analysis indicates that immobilization is associated with increased pain levels. ConclusionsThere is a statistically significant relationship between acute trauma pain, anxiety, fear, cold and immobilization.

The pelvic vascular injury score (P-VIS): a prehospital instrument to detect significant vascular injury in pelvic fractures

PurposeThe purpose of this study was to identify predictive factors for peri-pelvic vascular injury in patients with pelvic fractures and to incorporate these factors into a pelvic vascular injury score (P-VIS) to detect severe bleeding during the prehospital trauma management.MethodsTo identify potential predictive factors, data were taken (1) of a Level I Trauma Centre with 467 patients (ISS ≥ 16 and AISPelvis ≥ 3). Analysis including patient’s charts and digital recordings, radiographical diagnostics, mechanism and pattern of injury as well as the vascular bleeding source was performed. Statistical analysis was performed descriptively and through inference statistical calculation. To further analyse the predictive factors and finally develop the score, a 10-year time period (2012–2021) of (2) the TraumaRegister DGU® (TR-DGU) was used in a second step. Relevant peri-pelvic bleeding in patients with AISPelvis ≥ 3 (N = 9227) was defined as a combination of the following entities (target group PVITR-DGUN = 2090; 22.7%): pelvic fracture with significant bleeding (> 20% of blood volume), Injury of the iliac or femoral artery or blood transfusion of ≥ 6 units (pRBC) prior to ICU admission. The multivariate analysis revealed nine items that constitute the pelvic vascular injury score (P-VIS).ResultsIn study (1), 467 blunt pelvic trauma patients were included of which 24 (PVI) were presented with significant vascular injury (PVI, N = 24; control (C, N = 443). Patients with pelvic fractures and vascular injury showed a higher ISS, lower haemoglobin at admission and lower blood pressure. Their mortality rate was higher (PVI: 17.4%, C: 10.3%). In the defining and validating process of the score within the TR-DGU, 9227 patients met the inclusion criteria. 2090 patients showed significant peripelvic vascular injury (PVITR-DGU), the remaining 7137 formed the control group (CTR-DGU). Nine predictive parameters for peripelvic vascular injury constituted the peripelvic vascular injury score (P-VIS): age ≥ 70 years, high-energy-trauma, penetrating trauma/open pelvic injury, shock index ≥ 1, cardio-pulmonary-resuscitation (CPR), substitution of > 1 l fluid, intubation, necessity of catecholamine substitution, remaining shock (≤ 90 mmHg) under therapy. The multi-dimensional scoring system leads to an ordinal scaled rating according to the probability of the presence of a vascular injury. A score of ≥ 3 points described the peripelvic vascular injury as probable, a result of ≥ 6 points identified a most likely vascular injury and a score of 9 points identified an apparent peripelvic vascular injury. Reapplying this score to the study population a median score of 5 points (range 3–8) (PVI) and a median score of 2 points (range 0–3) (C) (p < 0.001). The OR for peripelvic vascular injury was 24.3 for the patients who scored > 3 points vs. ≤ 2 points. The TR-DGU data set verified these findings (median of 2 points in CTR-DGU vs. median of 3 points with in PVITR-DGU).ConclusionThe pelvic vascular injury score (P-VIS) allows an initial risk assessment for the presence of a vascular injury in patients with unstable pelvic injury. Thus, the management of these patients can be positively influenced at a very early stage, prehospital resuscitation performed safely targeted and further resources can be activated in the final treating Trauma Centre.

Tranexamic acid and pre-hospital trauma setting: Is everything clear by now?

Abstract An early use of tranexamic acid (TXA) in polytrauma patients has long been emphasized, although several conflicting evidence make its applicability still controversial and claims debate. Several multicenter trials have been conducted and the latter appear to collide with recent evidence published in the literature. In particular, the putative effects of early prognostic and hospitalization are still far from a common recommendation. We believe conflicting evidence derives from an unproper standardization of the pre-hospital setting, where non-diversified demographic factors, such as sociodemographic ones and accessibility to resources, still play a significant and detrimental role in patients’ outcomes. Moreover, evaluation and investigation of the real benefits of TXA administration in the trauma patient according to the different settings or scenarios are required, as the availability of resources could represent a non-negligible bias that could lead to evidence too far from universal applicability and accessibility.

On Scene Injury Severity Prediction (OSISP) model for trauma developed using the Swedish Trauma Registry

BackgroundProviding optimal care for trauma, the leading cause of death for young adults, remains a challenge e.g., due to field triage limitations in assessing a patient’s condition and deciding on transport destination. Data-driven On Scene Injury Severity Prediction (OSISP) models for motor vehicle crashes have shown potential for providing real-time decision support. The objective of this study is therefore to evaluate if an Artificial Intelligence (AI) based clinical decision support system can identify severely injured trauma patients in the prehospital setting.MethodsThe Swedish Trauma Registry was used to train and validate five models – Logistic Regression, Random Forest, XGBoost, Support Vector Machine and Artificial Neural Network – in a stratified 10-fold cross validation setting and hold-out analysis. The models performed binary classification of the New Injury Severity Score and were evaluated using accuracy metrics, area under the receiver operating characteristic curve (AUC) and Precision-Recall curve (AUCPR), and under- and overtriage rates.ResultsThere were 75,602 registrations between 2013–2020 and 47,357 (62.6%) remained after eligibility criteria were applied. Models were based on 21 predictors, including injury location. From the clinical outcome, about 40% of patients were undertriaged and 46% were overtriaged. Models demonstrated potential for improved triaging and yielded AUC between 0.80–0.89 and AUCPR between 0.43–0.62.ConclusionsAI based OSISP models have potential to provide support during assessment of injury severity. The findings may be used for developing tools to complement field triage protocols, with potential to improve prehospital trauma care and thereby reduce morbidity and mortality for a large patient population.

Prehospital Care in Road Traffic Accident Cases

Abstract Background: Rapid population growth, industrialization and an increase in road vehicles, have led to a drastic increase in the number of Road Traffic Accidents (RTA).Pedestrians, motorized two wheeled vehicle (MTV) users, and cyclists are the most vulnerable road user groups in terms of injuries and fatalities resulting from road traffic crashes in India. At least one-third of potentially preventable deaths occur prior to arrival at hospital and over half occur during the hospital reception and resuscitation phase of care. Prehospital emergency care in India is only beginning to develop. Thirty per cent of emergency patients in India die before they reach a hospital. Persons who shift the victims are usually untrained members of the public. Crash victims are often taken to the nearest hospital, regardless of the hospital’s capabilities for dealing with trauma. The vast majority of ambulances are used for inter-hospital transfer, not for primary response. This highlights the need of urgent steps for establishing good pre-hospital care and trauma services at site in India. Aims and Objectives: The study attempts to know the status of provision of pre hospital care to RTA victims and to suggest measures for improving hospital and pre-hospital care to the same. Methods: The study was conducted on patients of RTI admitted at Trauma Centre of King George’s Medical University UP (KGMU), Lucknow. A semi-structured questionnaire was used gather information about the socio demographic profile of RTA victims and the status of provision of pre hospital care to them. Results: It was seen in the present study that only eight percent cases had some sort of pre-hospital care given, or some interventions done before victim was taken to the hospital. Majority of these interventions were given by the bystanders and included measures like shifting the victim from the accident site (76.5%), water splinting/fanning/water given to drink (8.8%), or wound covered with cloth (5.9%) or medications (8.8%). In 9.7 percent cases, it was not known whether any pre hospital intervention was given. Out of the total cases who died, 66.7 percent had not received any intervention before hospitalization. The proportion of mortality was 2.5 percent in cases where no interventions were given, while there was no mortality in cases where some interventions were given before hospitalization. Conclusion: It was seen that very few cases got some intervention before hospitalization and a number of cases were referred from government health facilities due to unavailability of beds, equipment or medical staff. About thirty percent interviewees were not aware of ambulance emergency number. Lower proportion of mortality was seen in cases that got intervention at a health facility within an hour.

A Review of75th Ranger Regiment Battle-Injured Fatalities Incurred During Combat Operations From 2001 to 2021.

The 75th Ranger Regiment is an elite U.S. military special operations unit that conducted over 20 years of sustained combat operations. The Regiment has a history of providing novel and cutting-edge prehospital trauma care, advancing and translating medical initiatives, and documenting and reporting casualty care performance improvement efforts. A retrospective case fatality rate (CFR) review, mortality review, and descriptive analysis of fatalities were conducted for battle-injured personnel assigned or attached to the 75th Ranger Regiment from 2001 to 2021 during combat operations primarily in Afghanistan and Iraq. Fatalities were evaluated for population characteristics, cause of death, mechanism of death, injury severity, injury survivability, and death preventability. A total of 813 battle injury casualties, including 62 fatalities, were incurred over 20 years and 1 month of continuous combat operations. The Regiment maintained a zero rate of prehospital preventable combat death. Additionally, no fatalities had a mechanism of death because of isolated extremity hemorrhage, tension pneumothorax, or airway obstruction. When comparing the CFR of the Regiment to the U.S. military population as a whole, the Regiment had a significantly greater reduction in the cumulative CFR as measured by the difference in average annual percentage change. Documentation and analysis of casualties and care, mortality and casualty reviews, and other performance improvement efforts can guide combatant commanders, medical directors, and fighting forces to reduce preventable combat deaths and the CFR. Early hemorrhage control, blood product resuscitation, and other lifesaving interventions should be established and maintained as a standard prehospital practice to mitigate fatalities with potentially survivable injuries.

Performance Assessment of Out-of-Hospital Use of Pelvic Circumferential Compression Devices for Severely Injured Patients in Switzerland: A Nationwide Retrospective Cross-Sectional Study.

Patients with severe pelvic fractures carry a greater risk of severe bleeding, and pelvic compression devices (PCCD) are used to stabilize the pelvis on the pre-hospital scene. The aim of this study was to describe the use of PCCD in the pre-hospital setting on a nationwide scale (Switzerland) and determine the sensitivity, specificity and rates of over- and under-triage of the current application practices. The secondary objective was to identify pre-hospital factors associated with unstable pelvic fractures. Retrospective cross-sectional study using anonymized patient data (1 January 2015-31 December 2020) from the Swiss Trauma Registry (STR). Based on AIS scores, patients were assigned a unique principal diagnosis among three categories (unstable pelvic fracture-stable pelvic fracture-other) and assessed for use or not of PCCD. Secondarily, patient characteristics, initial pre-hospital vital signs, means of pre-hospital transport and trauma mechanism were also extracted from the database. 2790 patients were included for analysis. A PCCD was used in 387 (13.9%) patients. In the PCCD group, 176 (45.5%) had an unstable pelvic fracture, 52 (13.4%) a stable pelvic fracture and 159 (41.1%) an injury unrelated to the pelvic region. In the group who did not receive a PCCD, 214 (8.9%) had an unstable pelvic fracture, 182 (7.6%) a stable pelvic fracture and 2007 (83.5%) an injury unrelated to the pelvic region. The nationwide sensitivity of PCCD application was 45.1% (95% CI 40.1-50.2), the specificity 91.2% (95% CI 90-92.3), with both over- and under-triage rates of 55%. The prevalence of unstable fractures in our population was 14% (390/2790). We identified female sex, younger age, lower systolic blood pressure, higher shock index, pedestrian hit and fall ≥3 m as possible risk factors for an unstable pelvic fracture. Our results demonstrate a nationwide both over- and under-triage rate of 55% for out-of-hospital PCCD application. Female gender, younger age, lower blood pressure, higher shock index, pedestrian hit and fall >3 m are possible risk factors for unstable pelvic fracture, but it remains unclear if those parameters are relevant clinically to perform pre-hospital triage.

Development of Prehospital Factors for Predicting Massive Blood Transfusion in Trauma Patients

Background: Massive blood loss is the primary cause of immediate death in trauma patients. In prehospital care, where laboratory and investigation resources are limited, a massive blood transfusion (MBT) scoring system could activate blood bank preparation of blood components and facilitate EMS decision-making regarding the appropriate trauma center destination. This is particularly significant in urban environments where motor vehicle accidents are highly prevalent. Materials and Methods: A retrospective cohort study was conducted using data from prehospital trauma patients. Predictive parameters, including vital signs, mechanism of injury, and serious injury body parts, were analyzed, and the significant parameters identified by a multivariable analysis were used to develop a clinical scoring system. Discrimination was evaluated by the area under the receiver operating characteristic (AuROC) curve, calibration was demonstrated with the Hosmer-Lemeshow goodness of fit test, and internal validation was performed. Results: Among 511 trauma patients, 72 (14.1%) received MBT. The prehospital factors that significantly predicted massive MBT included hypotension with a SBP of less than 90 mmHg, penetrating object injuries, serious injuries to the face, thorax, abdomen, extremities including the pelvis, and the use of life-saving interventions such as advanced airway management and pelvic binding. The AuROC was 0.943 (95% CI 0.914 to 0.972, p&lt;0.001). The probability of receiving massive transfusion was 94.79% in patients with score of 5 or higher. Conclusion: The prehospital MBT score demonstrates good performance and discrimination for predicting MBT using simple and rapidly obtainable parameters in a prehospital setting.

Prehospital times and outcomes of patients transported using an ambulance trauma transport protocol: A data linkage analysis from New South Wales Australia

IntroductionPrehospital trauma systems are designed to ensure optimal survival from critical injuries by triaging and transporting such patients to the most appropriate hospital in a timely manner. ObjectivesWe sought to evaluate whether prehospital time and location (metropolitan versus non-metropolitan) were associated with 30-day mortality in a cohort of patients transported by road ambulance using a trauma transport protocol. MethodsData linkage analysis of routinely collected ambulance and hospital data across all public hospitals in New South Wales (NSW). The data linkage cohort included adult patients (age ≥ 16years) transported by NSW Ambulance, where a T1 Major Trauma Transport Protocol was documented by paramedic crews and transported by road to a public hospital emergency department in NSW for two years between January 2019 and December 2020. The outcomes of interest were prehospital times (response time, scene time and transport time) and 30-day mortality due to injury. Results9012 cases were identified who were transported to an emergency department with T1 protocol indication. Median prehospital transport times were longer in non-metropolitan road transports [n = 3,071, 98 min (71–126)] compared to metropolitan transports [n = 5,941, 65 min (53–80), p < 0.001]. There was no significant difference in 30-day mortality between the two groups (1.24% vs 1.65%, p = 0.13). In the subgroup of patients with abnormal vital signs, the only predictors of mortality were increasing age, presence of severe injury (OR 24.87, 95%CI 11.02, 56.15, p < 0.001), and arrival at a non-trauma facility (OR 3.01, 95%CI 1.26, 7.20, p < 0.05). Increasing transport times were not found to increase the odds of 30-day mortality. DiscussionIn the context of an inclusive trauma system and an established prehospital major trauma protocol, increasing prehospital transport times and scene location were not associated with increased mortality.

The forgotten cohort-lessons learned from prehospital trauma death: a retrospective cohort study

BackgroundTrauma related deaths remain a relevant public health problem, in particular in the younger male population. A significant number of these deaths occur prehospitally without transfer to a hospital. These patients, sometimes termed “the forgotten cohort”, are usually not included in clinical registries, resulting in a lack of information about prehospitally trauma deaths. The aim of the present study was to compare patients who died prehospital with those who sustained life-threatening injuries in order to analyze and potentially improve prehospital strategies.MethodsThis cohort study included all primary operations carried out by Switzerland's largest helicopter emergency medical service (HEMS) between January 1, 2011, and December 31, 2021. We included all adult trauma patients with life-threatening or fatal conditions. The outcome of this study is the vital status of the patient at the end of mission, i.e. fatal or life-threatening. Injury, rescue characteristics, and interventions of the forgotten trauma cohort, defined as patients with a fatal injury (NACA score of VII), were compared with life-threatening injuries (NACA score V and VI).ResultsOf 110,331 HEMS missions, 5534 primary operations were finally analyzed, including 5191 (93.8%) life-threatening and 343 (6.2%) fatal injuries. More than two-thirds of patients (n = 3772, 68.2%) had a traumatic brain injury without a significant difference between the two groups (p > 0.05). Thoracic trauma (44.6% vs. 28.7%, p < 0.001) and abdominal trauma (22.2% vs. 16.1%, p = 0.004) were more frequent in fatal missions whereas pelvic trauma was similar between the two groups (13.4% vs. 12.9%, p = 0.788). Pneumothorax decompression rate (17.2% vs. 3.7%, p < 0.001) was higher in the forgotten cohort group and measures for bleeding control (15.2% vs. 42.7%, p < 0.001) and pelvic belt application (2.9% vs. 13.1% p < 0.001) were more common in the life-threating injury group.ConclusionChest decompression rates and measures for early hemorrhage control are areas for potential improvement in prehospital care.

Untapped potential of commercial drivers in providing post-crash care to road traffic accident victims: A cross-sectional study from fast urbanizing city of Jodhpur, India.

Most road traffic accident (RTA) deaths occur before victim reaches a definitive trauma care facility. The aim of the study was to determine the role of commercial drivers toward providing post-crash care to RTA victims in Jodhpur, Rajasthan. This cross-sectional study assessed the role of commercial auto-rickshaw and cab drivers for providing post-crash care in urban Jodhpur during 2019-2020. Eligible participants volunteering for the study were included from taxi and auto stands in urban Jodhpur. A pre-tested questionnaire was administered by a trained interviewer. Data analysis was done using SPSS v23.0. Summary measures in terms of frequencies, means, and range are reported. Chi-square test, Fisher's Exact test, and Multivariate Logistic Regression analysis were done for statistical associations. Two hundred male participants completed the study with a mean age of 37.74 (8.96) years having an average work experience as commercial drivers of more than 10 years. Over 70% of participants witnessed RTA in the past year and 52% provided care to victims. The knowledge of post-crash care was most affected by their education level (adjusted odds ratio [aOR]: 1.778, 95% confidence interval [CI]: 0.958, 3.301), whereas the intended post-crash care practices were significantly better among participants with previous training (aOR: 15.376, 95% CI: 2.149, 110.017). The current study establishes the role of commercial drivers as first responders at accident sites in the fast urbanizing city of Jodhpur, Rajasthan. Systematic capacity building initiatives of commercial drivers to salvage RTA victims have potential to strengthen pre-hospital trauma care continuum in non-metro districts of India experiencing high burden of accidents.

Clinical application of a body area network-based smart bracelet for pre-hospital trauma care.

This study aims to explore the efficiency and effectiveness of a body area network-based smart bracelet for trauma care prior to hospitalization. To test the efficacy of the bracelet, an observational cohort study was conducted on the clinical data of 140 trauma patients pre-admission to the hospital. This study was divided into an experimental group receiving smart bracelets and a control group receiving conventional treatment. Both groups were randomized using a random number table. The primary variables of this study were as follows: time to first administration of life-saving intervention, time to first administration of blood transfusion, time to first administration of hemostatic drugs, and mortality rates within 24 h and 28 days post-admission to the hospital. The secondary outcomes included the amount of time before trauma team activation and the overall length of patient stay in the emergency room. The measurement results for both the emergency smart bracelet as well as traditional equipment showed high levels of consistency and accuracy. In terms of pre-hospital emergency life-saving intervention, there was no significant statistical difference in the mortality rates between both groups within 224 h post-admission to the hospital or after 28-days of treatment in the emergency department. Furthermore, the treatment efficiency for the group of patients wearing smart bracelets was significantly better than that of the control group with regard to both the primary and secondary outcomes of this study. These results indicate that this smart bracelet has the potential to improve the efficiency and effectiveness of trauma care and treatment. A body area network-based smart bracelet combined with remote 5G technology can assist the administration of emergency care to trauma patients prior to hospital admission, shorten the timeframe in which life-saving interventions are initiated, and allow for a quick trauma team response as well as increased efficiency upon administration of emergency care.

A Systematic Review of Live Animal Use as a Simulation Modality (“Live Tissue Training”) in the Emergency Management of Trauma

Live anaesthetized animals are used as simulation models to teach techniques in the emergency management of trauma. We aimed to explore how "live tissue training" (LTT) is designed, delivered and evaluated in order to better understand and characterize aspects of educational merit. A systematic review was performed using PRISMA guidance. A combined approach, involving a 3-stage modified narrative synthesis process and reflexive thematic analysis was used to identify key concepts across the published literature. Qualitative synthesis of 48 selected articles suggests that LTT is mainly used to teach military and civilian physicians and military medical technicians. The procedures trained vary with the learner population, from simple pre-hospital trauma tasks to advanced operative surgical skills. Many courses use a combination of didactic and practical training, with an animal model used to train practical application of knowledge and procedural skills. Descriptions of the learning interventions are limited, and explicit use of educational theory or pedagogic frameworks were absent within the literature. Four themes were identified regarding aspects of LTT that are valued by learners: "recreating the experience," relating to fidelity and realism; "tick tock" "dynamics of hemorrhage", encompassing the impact of bleeding and urgent pressure to act; "emotional impact" of conducting the training, and "self-efficacy: I believe I can do it." Thematic analysis of published literature suggests that there may be educational benefit in the use of live tissue models due to time criticality and bleeding, which creates a real-life event. LTT also invokes an emotional response, and learners experience an increase in self-efficacy from participation. We consider that these aspects and associated pedagogy should be addressed when researching and developing alternative simulation modalities, in order to intelligently replace, reduce and refine the use of animals in training practitioners in the emergency management of trauma.

National trends in prehospital penetrating trauma in 2020 and 2021

ObjectivePrior studies identified increased penetrating trauma rates during the earlier phase of the COVID-19 pandemic, but there is limited study of penetrating trauma rates in 2021 or at a national level. We evaluated trends in prehospital encounters for penetrating trauma in 2020 and 2021 using a national database. MethodsWe conducted a retrospective analysis of the National Emergency Medicinal Services (EMS) Information System (NEMSIS) combined 2018–2021 databases of prehospital encounters. We calculated penetrating trauma yearly and monthly rates with 95% confidence; both overall and for each census region. We compared trauma rates in 2020 and 2021 to combined 2018/2019. ResultsThere were 67,457 (rate of 0.30%) penetrating traumas in 2018, 86,054 (0.30%) in 2019, 95,750 (0.37%) in 2020, and 98,040 (0.34%) in 2021. Nationally, trauma rates were higher from March 2020 to July 2021 than baseline. Penetrating trauma rates from May–December 2021 were lower than May–December of 2020. All census regions similarly had increased trauma rates during from March 2020 to July 2021. ConclusionWe identified elevated rates of trauma on 2020 that lasted until July of 2021 that was present in all US census regions.

Preclinical care of children with multiple trauma

Severe multiple trauma in children is rare with approximately 380-550cases per year in Germany. In addition to the S3 guideline "Polytrauma", which was published more than a decade ago, the S2Kguideline "Severe multiple trauma care in childhood" was published in 2020. Accidents and especially the resulting traumatic brain injuries still represent the most frequent cause of death in children. While prehospital treatment according to Prehospital Trauma Life Support (PHTLS®) is basically analogous to that in adults which is based on the ABCDE concept (airway, breathing, circulation, disability, exposure), knowledge of age-dependent anatomical-physiological characteristics is essential. For simplification, various tools and dosing aids, such as the pediatric emergency ruler and specific emergency tables, are available. Further treatment after initial preclinical care should take place in an interdisciplinary manner in designated pediatric trauma centers.

Primary care doctors in acute call-outs to severe trauma incidents in Norway – associations with factors related to patients and doctors

Objective Severe trauma patients need immediate prehospital intervention and transfer to a specialised trauma hospital. In Norway, primary care doctors (PCDs) are an integrated part of the prehospital trauma care. The aim of this study was to investigate the degree to which PCDs were involved in prehospital care of severe trauma patients and how factors related to patients and doctors were associated with call-outs to these incidents. Design This was a registry-based study in Norway on severe trauma patients with acute hospital admission during the period 2012–2018. Setting Data was obtained from three Norwegian official registries. Subjects By linking the registries, we studied the actions taken by the PCDs, whether they called out to severe trauma incidents. Main outcome measures In multivariable regression models, we investigated whether factors related to the PCDs (age, sex, specialisation in general practice (GP)) and patients (age, sex, duration of hospital stay, type of injury) were associated with call-outs. Results Out of 4342 severe trauma incidents, PCDs had documented involvement in 1683 (39%) and called out to 644 (15%). Increased proportions of PCD call-outs to severe trauma incidents were significantly associated with lower age of PCD, being a GP specialist, lower patient age, being a male patient, increased length of hospital stay and injuries to the head and the neck. Conclusions PCDs called out to a relatively low proportion of severe trauma patients. Several factors related to patients and doctors were associated with call-outs to severe trauma incidents in Norway.

Exploring the characteristics of successful prehospital trauma care teams: Insights from military trauma care simulations.

Trauma care teams play a crucial role in determining the outcomes of trauma victims. The composition and training of these teams can vary. Our study seeks to examine the characteristics of successful military Advanced Life Support (ALS) teams and the factors that affect them. A retrospective study was conducted at the Israel Defense Force (IDF) Military Medical Academy throughout 2021, where prehospital medical teams were observed in trauma care simulations. Teams were led by ALS providers (military physicians or paramedics) trained in IDF Military Trauma Life Support. Demographic and training data were collected. Teams were categorized into high or subpar performance groups based on simulation scores. Specific skills were assessed by trauma instructors using a points system. Scores were compared between the groups and analyzed for correlations with demographic and training data. Overall, 63 team simulations were analyzed, with teams led by a military paramedic in 78% of simulations. The mean overall simulation performance was 81% ±6.2, and there were no differences in scores of single or multicasualty simulations. A total 3% of the teams achieved successful results and were more likely to have a paramedic as the ALS provider ( p = 0.028). A sensitivity analysis excluding physicians was conducted and showed that high-performance teams had significantly higher skill assessments for primary survey ( p = 0.004), injury recognition ( p = 0.002), exposure ( p = 0.006), adherence to clinical practice guidelines ( p = 0.032), and medical device use ( p = 0.002). Our study found that ALS provider is associated with overall simulation performance in prehospital ALS teams, with military paramedics more likely to be successful. These findings have implications for the training and staffing of prehospital ALS teams, suggesting that teams should be composed accordingly and that training should focus on skills affected by the ALS provider type.

Celebrating Global Road Safety Week.

May 15-21, 2023 is Global Road Safety Week hosted by the World Health Organization to raise awareness about road safety and opportunities for prevention. Lifestyle practitioners and health care providers can contribute to these efforts in many ways from counseling patients to change risky behaviors to supporting efforts to improve pre-hospital trauma care.

Developing Prehospital Care in India–A Potential Model for Low- and Middle-income Countries

Introduction:Road traffic accidents and natural disasters cause significant numbers of deaths and life-changing injuries in low &amp; middle-income countries. Most of these countries have limited resources for pre-hospital care and training. In 2021, there were 155,622 deaths due to road accidents and &gt;18,000 railway-related deaths. Natural and manmade disasters also contribute to high numbers of serious injuries and deaths in the region. India is the pilot for developing an international training course for prehospital trauma care.Method:A review of pre-hospital care training and ambulance services in Tamil Nadu and Kerala states of India was carried out in 2019. An international workshop on developing pre-hospital care in India was held in Chennai in October 2022. The workshop included experts from UK and India and 52 practitioners from various parts of India.Results:India has developed a country-wide ambulance service sub-contracted to private providers under a public-private partnership initiative and in addition, there are private and charitable providers. In-transit care and resuscitation are limited and the vehicles are primarily a transport mechanism with a scoop-and-run policy. Infrastructure, traffic congestion, rural and hard-to-reach areas, poorly equipped ambulance services and variations in training and scope of practice contribute to the challenges of providing high quality pre-hospital care.Conclusion:There is a need for high-quality pre-hospital care training, regulation and continuing professional development within the pre-hospital care sector. Delivery of pre-hospital care could be reinforced by wider involvement of doctors such as General Practitioners and other allied health care professionals. It was agreed by all delegates and speakers that an international course on pre-hospital care based upon an existing UK course from the Faculty of Pre-Hospital Care of the Royal College of Surgeons of Edinburgh, edited to take account of India’s current resources, should be piloted in Chennai in 2023.
