Multiple Trauma in Young and Elderly: Are There Any Differences?

Abstract Background:  Old age is considered a risk factor; however, its effect on the prognosis of injured elderly patients remains uncertain. Aim:  To find the effect of old age on final outcome of elderly patients withmultiple trauma and to determine whether a different therapeutic approach is needed. Methods:  All patients with at least two injured body regions, as defined by the ISS, of grade 4 in AIS, were included. Results:  We studied 165 patients up to 64 years (Y) of age and 56 patients older than 65 years (E) in a 10-year period. On presentation 21.2% of Y and 25% of E, were hypovolemic (p = NS). No significant difference in number of injuries/patient was noted between Y and E patients, hemodynamically stable (HS) and unstable (HU) – (3.0 vs. 2.9 and 3.9 vs. 3.6). An increased relative frequency of chest and abdomen injuries was noted in Y and E, who died or were HU on presentation. A higher relative frequency of long bone and pelvis fractures was noted in the E. The ISS was not different among HS and HU, Y and E. Hospitalization in ICU was more common in E than in Y (69.6 vs. 47.3%), but there was no difference in the final outcome: overall mortality was 10.3% in Y versus 16.1% in E (p = NS), mortality in HU was 42.9% in Y versus 50% in E (p = NS). ISS was not associated with mortality in either group. Conclusions:  Old age has no influence on final outcome of E multi trauma patients; hence, the therapeutic approach of these patients should be the same in Y.     

Predicting Health-related Quality of Life of Severely Injured Patients: Sociodemographic,Economic, Trauma,and Hospital Stay-related Determinants

Abstract Introduction:  Due to remarkable improvements in emergency and intensive care medicine in the recent past, the mortality rate for severely injured patients is decreasing. Outcome research therefore should no longer focus only on questions of survival, but also on aspects of the quality of life after severe trauma. This study examined the long-term effect of different sociodemographic, economic, trauma, and hospital-related factors on the health-related quality of life (SF-36) of severely injured patients. Patients and Methods:  A written questionnaire was sent to 121 trauma patients who received treatment in two hospitals in Cologne/Northrhine-Westfalia between 1996 and 2001. The inclusion criteria were more than one injury and a sum of abbreviated injury score of the two worst injuries ≥ 6. The response rate after using the total-design-method was 77.6% (n = 90). Results:  Severely injured patients showed significant reductions for all subscales of the SF-36, on average 4 years after discharge on average, in comparison to a German norm population. Specifically, aspects of the physical-component scale were dramatically reduced. Linear regressions controlling for time after discharge suggested that higher age, lower socioeconomic status, living together with a partner, and the severity of trauma and injury of extremities were significant predictors for a reduced quality of life, while satisfaction with the hospital stay had a positive effect. Discussion:  All in all, it is important to identify trauma- patients who will suffer a reduced quality of life. In so doing, it will be possible to take into account the specific circumstances of their recovery during medical treatment, care, and rehabilitation.     

Long-Term Health-Related Quality of Life in Major Pediatric Trauma: A Pilot Study

Abstract Background:   Major trauma is the leading cause of mortality and morbidity in children of developed countries. Little research has been done about the health-related quality of life (HRQL) in these children. The aim of the current research is to describe the HRQL of children in the long term after major trauma and to compare it with healthy peers. Methods:   A prospective cohort study of severely injured children (ISS ≥ 16, age < 16 years) who survived the trauma and were admitted to the emergency department of a Dutch level 1 trauma center in 1999 and 2000 (n = 40) was conducted. Between 6 and 8 years after trauma (mean 7.3, SD 0.7 years), outcome was assessed by the Pediatric Quality of Life Inventory (PedsQL 4.0), the EuroQol 5D (EQ-5D), and the EuroQol Visual Analogue Scale (EQ-VAS). Results:   The mean age at the time of the accident was 8.9 years (SD 4.6 years), the mean ISS was 24.9 (SD 11.1), and 25 (63%) cases were male; 28 out of 40 patients were followed up. The mean score on the PedsQL was 81.2 and this did not differ significantly from the norm value. On the EQ-5D, more health problems were reported than in a healthy reference population. The mean EQ-VAS score was 79.4 and was significantly lower than in healthy peers. The lowest scores on the PedsQL and the EQ-VAS were seen in teenagers and in respondents with spinal cord and/or severe cerebral injury. Conclusion:   The results on HRQL in children in the long term after major trauma are inconclusive. Special attention should be given to teenagers with spinal cord or severe cerebral injury who reported the lowest HRQL.     

Is the Grading of Liver Injuries a Useful Clinical Tool in the Initial Management of Blunt Trauma Patients?

Abstract Background:   Computed tomography (CT) has become the preferred method for evaluation of the abdomen for victims of blunt trauma. Grading of liver injuries, primarily by CT, has been advocated as a measure of severity and, by implication, the likelihood for intervention or complications. We have sought to determine if grading of liver injuries, as a clinical tool, affects immediate or extended management of patients. Methods:   We have retrospectively reviewed all patients sustaining blunt liver injuries as diagnosed by CT over a five-year period at a Level I trauma center to determine if grading of injury influenced management. The AAST organ scaling system was utilized (major grade 4–5, minor grade 1–3), as well as the ISS, AIS, mortality, morbidity, and treatment. There were 133 patients available for review. The patients were grouped into major (n = 20) and minor (n = 113) liver injuries and operative (n = 12) and nonoperative (n = 121) management. Results:   Major liver injuries had a higher ISS (39 + 13 vs. 27 + 15, p = 0.001) and were more likely to require operative intervention (5/20 vs. 7/113, p = 0.02). Mortality in this group was not different (major vs. minor), and there were no differences in the incidence of complications. Twelve patients (9%) required operation, all for hemodynamic instability, all within 24 h, and 11/12 within 6 h. At operation 8/12 patients had other sources of bleeding beside the liver injury, and 7/12 had minor hepatic injuries. The operative patients had higher ISS and AIS scores (head/neck, chest, abdomen, extremities) than those managed nonoperatively. More patients died in the operative group (6/12 vs. 8/121, p = 0.0003). There were more pulmonary (6/12 vs. 16/121, p = 0.005), cardiovascular (6/12 vs. 19/121, p = 0.01), and infectious (5/12 vs. 20/121, p = 0.049) complications in the operative group. There were 14 deaths overall; 13/14 were due to traumatic brain injury, and 8/14 required urgent operation for hemorrhage. Conclusions:   In conclusion, grading of liver injuries does not seem to influence immediate management. Physiologic behavior dictated management and need for operative intervention, as well as prognosis. However, both major hepatic injuries and need for early operation reflected overall severity and the possibility of associated injuries.     

Comparison of Injury Pattern in Victims of Bear (Ursus thibetanus) and Leopard (Panthera pardus) Attacks. A Study from a Tertiary Care Center in Kashmir

Abstract Introduction:   Patients injured in bear and leopard attacks present with different patterns of injuries and have different mortality rates. A common protocol may not be suitable for the management of injuries inflicted by these two large wild animals. Materials and Methods:   A retrospective study was conducted by the Department of Orthopedics, Government Medical College Srinagar (India) to compare the injury patterns among victims of bear and leopard attacks. Results:   One hundred and fifty-five cases with 120 (77.4%) bear and 35 (22.5%) leopard attacks were recorded over a period of 43 months. Eighty-six males and 34 females including two children were injured in bear attacks. Eleven males and 24 females including 13 children were attacked by leopards. The leopard attacks were usually fatal (48.5%), whereas the bear attacks were mostly nonfatal in nature (1.6%). The patients had a combination of injuries affecting multiple parts of the body. Injuries of the cervical spine, cervical cord, major vessels of neck, pharynx and eye were striking observations in leopard attacks. Fractures of the upper limb, facial and skull bones were common in the victims of bear attacks. The survivors were treated as per advanced life trauma support, with an average follow-up of 24.5 months (5–42 months). Conclusion:   Wild animals usually attack in remote areas, where composite trauma centers do not exist, and the urgent referrals of these patients will have a significant impact on the final outcome. The management of these patients requires a team approach involving all of the subspecialties of traumatology.     

Improving early identification of the high-risk elderly trauma patient by emergency medical services

Study objectiveWe sought to (1) define the high-risk elderly trauma patient based on prognostic differences associated with different injury patterns and (2) derive alternative field trauma triage guidelines that mesh with national field triage guidelines to improve identification of high-risk elderly patients.MethodsThis was a retrospective cohort study of injured adults ≥65 years transported by 94 EMS agencies to 122 hospitals in 7 regions from 1/1/2006 through 12/31/2008. We tracked current field triage practices by EMS, patient demographics, out-of-hospital physiology, procedures and mechanism of injury. Outcomes included Injury Severity Score ≥ 16 and specific anatomic patterns of serious injury using abbreviated injury scale score ≥3 and surgical interventions. In-hospital mortality was used as a measure of prognosis for different injury patterns.Results33,298 injured elderly patients were transported by EMS, including 4.5% with ISS ≥ 16, 4.8% with serious brain injury, 3.4% with serious chest injury, 1.6% with serious abdominal-pelvic injury and 29.2% with serious extremity injury. In-hospital mortality ranged from 18.7% (95% CI 16.7–20.7) for ISS ≥ 16 to 2.9% (95% CI 2.6–3.3) for serious extremity injury. The alternative triage guidelines (any positive criterion from the current guidelines, GCS ≤ 14 or abnormal vital signs) outperformed current field triage practices for identifying patients with ISS ≥ 16: sensitivity (92.1% [95% CI 89.6–94.1%] vs. 75.9% [95% CI 72.3–79.2%]), specificity (41.5% [95% CI 40.6–42.4%] vs. 77.8% [95% CI 77.1–78.5%]). Sensitivity decreased for individual injury patterns, but was higher than current triage practices.ConclusionsHigh-risk elderly trauma patients can be defined by ISS ≥ 16 or specific non-extremity injury patterns. The field triage guidelines could be improved to better identify high-risk elderly trauma patients by EMS, with a reduction in triage specificity.     

Is Routine Spiral CT-Chest Justified in Evaluation of the Major Blunt Trauma Patients?

Abstract Study:   New generation spiral CT scanners permit multiple consecutive CT examinations on the same trauma patient in a short period of time. The purpose of this study was to evaluate the diagnostic role and therapeutic impact of routine spiral CT chest in multiply injured patients or patients with a suspicious mechanism of injury. Patients and Methods:   This prospective study included 443 patients with blunt chest trauma. All patients underwent a spiral CT chest as part of their routine evaluation. Radiological interpretation of chest x-rays, CT scan findings, and changes in management plan guided by these findings were recorded. Results:   The mechanism of injury was road traffic accidents in 422 patients (95.26%). Out of the 167 patients with normal chest radiograph, 136 (81.43%) were found to have an abnormality on chest CT. The management was changed in the form of additional investigations or unplanned intervention in 92 patients (20.76%). Additional investigations included transoesophageal echocardiography (n = 7), bronchoscopy (n = 13), transfer to higher center for aortography (n = 2). Intercostal tubes (n = 55), thoracotomies (n = 4), fixation of sternal fracture (n = 9), laparotomy (n = 1) and spinalfixation (n = 1) were performed following the CT scan. Conclusion:   Although the incidence of significant injuries identified by the chest CT scan was low, it did prompt immediate intervention in a significant number of patients; some of them had potentially life-threatening injuries. Routine use of CT scanning is warranted in early evaluation of polytrauma patients or patients with severe blunt chest trauma.     

The association of hand and wrist injuries with other injuries in multiple trauma patients. A retrospective study in a UK Major Trauma Centre

BackgroundApproximately 20,000 major trauma cases occur in England every year. However, the association with concomitant upper limb injuries is unknown. This study aims to determine the incidence, injury pattern and association of hand and wrist injuries with other body injuries and the Injury Severity Score (ISS) in multiply injured trauma patients.MethodsSingle centre retrospective study was performed at a level-one UK Major Trauma Centre (MTC). Trauma Audit and Research Network (TARN) eligible multiply injured trauma patients that were admitted to the hospital between January 2014 and December 2018 were analysed. TARN is the national trauma registry. Eligible patients were: a trauma patient of any age who was admitted for 72 h or more, or was admitted to intensive care, or died at the hospital, was transferred into the hospital for specialist care, was transferred to another hospital for specialist care or for an intensive care bed and whose isolated injuries met a set of criteria. Data extracted included: age, gender, mode of arrival, location of injuries including: hand and/or wrist and mechanism of injury. We performed a logistic regression analysis to assess the association between hand/wrist injury to ISS score of 15 points or above/below and to the presentation of other injuries.Results107 patients were analysed. Hand and wrist injuries were the second most common injury (26.2%), after thoracic injuries. Distal radial injuries were found in 5.6%, carpal/carpometacarpal in 6.5%, concurrent distal radius and carpometacarpal in 0.9%, phalangeal injuries in 4.7%, tendon injuries in 0.9% and concurrent hand and wrist injuries in 7.5% cases. There was a significant association between hand or wrist injuries and lower limb injuries (Odds Ratio (OR): 3.84; 95% confidence intervals (CI): 1.09 to 13.50; p = 0.04) and pelvic injuries (OR: 4.78; 95% CI: 1.31 to 17.44; p = 0.02). There was no statistical association between hand and wrist injuries and ISS score (OR: 0.80; 95% CI: 0.11 to 5.79; p = 0.82).ConclusionsHand and wrist injuries are prevalent in trauma patients admitted to MTCs. They should not be under-estimated but routinely screened for in multiply injured patients particularly those with a pelvic or lower limb injury.     

Nonoperative Management of Blunt Splenic Trauma: Also Feasible and Safe in Centers with Low Trauma Incidence and in the Presence of Established Risk Factors

Abstract Background:   Treatment of blunt splenic trauma has undergone dramatic changes over the last few decades. Nonoperative management (NOM) is now the preferred treatment of choice, when possible. The outcome of NOM has been evaluated. This study evaluates the results following the management of blunt splenic injury in adults in a Swedish university hospital with a low blunt abdominal trauma incidence. Method:   Fifty patients with blunt splenic trauma were treated at the Department of Surgery, Lund University Hospital from January 1994 to December 2003. One patient was excluded due to a diagnostic delay of > 24 h. Charts were reviewed retrospectively to examine demographics, injury severity score (ISS), splenic injury grade, diagnostics, treatment and outcome measures. Results:   Thirty-nine patients (80%) were initially treated nonoperatively (NOM), and ten (20%) patients underwent immediate surgery (operative management, OM). Only one (3%) patient failed NOM and required surgery nine days after admission (failure of NOM, FNOM). The patients in the OM group had higher ISS (p < 0.001), higher grade of splenic injury (p < 0.001), and were hemodynamically unstable to a greater extent (p < 0.001). This was accompanied by increased transfusion requirements (p < 0.001), longer stay in the ICU unit (p < 0.001) and higher costs (p = 0.001). Twenty-seven patients were successfully treated without surgery. No serious complication was found on routine radiological follow-up. Conclusion:   Most patients in this study were managed conservatively with a low failure rate of NOM. NOM of blunt splenic trauma could thus be performed in a seemingly safe and effective manner, even in the presence of established risk factors. Routine follow-up with CT scan did not appear to add clinically relevant information affecting patient management.     

Delayed Presentations of Blunt Mesenteric and Intestinal Trauma in the Wake of Injury

Abstract Objective:  To analyze the presentation and timing of blunt mesenteric and intestinal trauma requiring surgical intervention. Methods:  The Hadassah-Hebrew University trauma registry was scanned for patients who required surgery following blunt mesenteric and/or bowel trauma. Demographic data, mechanism of injury, time to diagnosis and pathology reports were recorded. A literature search was also performed. Results:  The majority of patients were injured in motor vehicle accidents (26/30, 86.7%). Patients were divided into three groups. Seventeen patients diagnosed within 4 h of admission were defined as the immediate group. Indication for surgery was hemodynamic instability and/or peritonitis. The most commonly injured region was the terminal ileum (10/17 patients, 59%). The second group (n = 4) had surgery within 2 weeks of injury (early group). These patients presented initially with hemodynamic instability. The operative findings were consistent with a low-flow state of the terminal ileum and cecum. The third group (n = 9) consisted of patients who were operated later than 2 weeks from the date of injury (late group). These patients presented with prolonged abdominal symptoms, chiefly partial small bowel obstruction. Operative findings were bowel strictures, most commonly of the terminal ileum (7/9 patients, 77.8%). Conclusions:  Acceleration–deceleration abdominal injury affects the terminal ileum more commonly. We propose that the ensuing clinical picture depends on the level of energy transmitted: high-energy trauma leads to extensive mesenteric and bowel tears and is diagnosed immediately. Low-energy trauma may lead to chronic ischemia, fibrosis and stricture-formation. The right colon appears to be more vulnerable to lowflow states following blunt trauma.     

Evaluating pre-hospital triage and decision-making in patients who died within 30 days post-trauma: A multi-site,multi-center,cohort study

IntroductionEvaluating pre-hospital triage and decision-making in patients who died post-trauma is crucial to decrease undertriage and improve future patients’ chances of survival. A study that has adequately investigated this is currently lacking. The aim of this study was therefore to evaluate pre-hospital triage and decision-making in patients who died within 30 days post-trauma.Materials and methodsA multi-site, multi-center, cohort study was conducted. Trauma patients who were transported from the scene of injury to a trauma center by ambulance and died within 30 days post-trauma, were included. The main outcome was undertriage, defined as erroneously transporting a severely injured patient (Injury Severity Score ≥ 16) to a lower-level trauma center.ResultsBetween January 2015 and December 2017, 2116 patients were included, of whom 765 (36.2%) were severely injured. A total of 103 of these patients (13.5%) were undertriaged. Undertriaged patients were often elderly with a severe head and/or thoracic injury as a result of a minor fall (< 2 m). A majority of the undertriaged patients were triaged without assistance of a specialized physician (100 [97.1%]), did not meet field triage criteria for level-I trauma care (81 [78.6%]), and could have been transported to the nearest level-I trauma center within 45 min (93 [90.3%]).ConclusionApproximately 14% of the severely injured patients who died within 30 days were undertriaged and could have benefited from treatment at a level-I trauma center (i.e., specialized trauma care). Improvement of pre-hospital triage is needed to potentially increase future patients’ chances of survival.     

A Prospective Study of Penetrating Abdominal Trauma at the University of Calabar Teaching Hospital,Calabar, Southern Nigeria

Abstract Background:   Abdominal injuries are on the increase in both developed and developing countries. The frequency of penetrating abdominal trauma (PAT) varies across the globe because it relates to industrialization, the weapons available, and the presence of military conflicts. This study sought to evaluate the current pattern and outcome of managementof PAT in Calabar, which is undergoing rapid urbanization, and with a focus on tourism. Method:   Patients admitted to the University of Calabar Teaching Hospital, Calabar with PAT from February 2005 to January 2008 were prospectively studied. Results:   Seventy-nine patients presented with abdominal trauma, among which 39 (49%) were PAT. There were 37 males and two females, whose ages ranged from 5 to 54 years (mean 27.8 years). Stab wound (18; 46.1%) was the commonest injury, while gunshot wound (15; 38.5%) ranked second. Others were road traffic accident (two patients), fall, cow horn injury, shrapnel, and criminal abortion (a patient each). The commonest injury was evisceration of the omentum and small intestine, which occurred in 13 (36%) patients. Five (14%) patients suffered small intestinal perforations, while three (8%) had liver, splenic and colonic injuries, respectively. Others were rectal injury (four patients), mesenteric injury and perforated stomach (two patients each), and a patient with diaphragmatic injury. The outcome was fatal in two (5%) patients. Conclusion:   Penetrating abdominal trauma is on the increase in Calabar. The pattern of injury revealed areas which, when effectively contained, will lead to an improvement in the safety of our environment.     

Re-triage moderates association between state trauma funding and lower mortality of trauma patients

BackgroundSeverely injured patients who are re-triaged (emergently transferred from an emergency department to a high-level trauma center) experience lower in-hospital mortality. Patients in states with trauma funding also experience lower in-hospital mortality. This study examines the interaction of re-triage, state trauma funding, and in-hospital mortality.Study DesignSeverely injured patients (Injury Severity Score (ISS) >15) were identified from 2016 to 2017 Healthcare Cost and Utilization Project State Emergency Department Databases and State Inpatient Databases in five states (FL, MA, MD, NY, WI). Data were merged with the American Hospital Association Annual Survey and state trauma funding data. Patients were linked across hospital encounters to determine if they were appropriately field triaged, field under-triaged, optimally re-triaged, or sub-optimally re-triaged. A hierarchical logistic regression modeling in-hospital mortality was used to quantify the effect of re-triage on the association between state trauma funding and in-hospital mortality, while adjusting for patient and hospital characteristics.ResultsA total of 241,756 severely injured patients were identified. Median age was 52 years (IQR: 28, 73) and median ISS was 17 (IQR: 16, 25). Two states (MA, NY) allocated no funding, while three states (WI, FL, MD) allocated $0.09-$1.80 per capita. Patients in states with trauma funding were more broadly distributed across trauma center levels, with a higher proportion of patients brought to Level III, IV, or non-trauma centers, compared to patients in states without trauma funding (54.0% vs. 41.1%, p < 0.001). Patients in states with trauma funding were more often re-triaged, compared to patients in states without trauma funding (3.7% vs. 1.8%, p < 0.001). Patients who were optimally re-triaged in states with trauma funding experienced 0.67 lower adjusted odds of in-hospital mortality (95% CI: 0.50–0.89), compared to patients in states without trauma funding. We found that re-triage significantly moderated the association between state trauma funding and lower in-hospital mortality (p = 0.018).ConclusionSeverely injured patients in states with trauma funding are more often re-triaged and experience lower odds of mortality. Re-triage of severely injured patients may potentiate the mortality benefit of increased state trauma funding.     

Injury to the Thoracic Aorta Following Fatal Blunt Trauma: An Autopsy Study

Abstract Background:   Transection of the thoracic aorta (TTA) remains a leading cause of death after blunt trauma. In this autopsy study, the natural history of this injury is reviewed. Patients and Methods:   All blunt trauma deaths that occurred in the Milano urban area over a period of one year were collected. Autopsies were available in all cases. Incidence, mechanisms, anatomical locations of TTA, deaths due to TTA or coexisting injuries, and times of death were reviewed. Cause of death was established. Death was attributed to TTA if its abbreviated injury score was six (hemorrhage not confined to the mediastinum). Results:   199 cases of fatal blunt trauma were included, 72% of which were males; mean age 53 ± 21. A TTA was observed in 53 subjects (27%), with a significantly higher incidence between the ages of 45 and 64 years and after falls from height. The aorta was transected at the isthmus in 36% of cases. Victims with TTA had a higher pre-hospital mortality and more injuries to chest organs, the chest wall and pelvis. In victims with TTA, injury to the aorta was the cause of death in 58%. Only five patients with TTA survived more than 1 h, reaching the hospital alive; four of these died due to the rupture of a mediastinal hematoma during the first hours of in-hospital care. Conclusions:   This study demonstrates that TTA is a frequent cause of immediate deaths among blunt trauma victims. Patients with risk factors for TTA who reach the hospital alive need to be promptly investigated with a contrast CT scan. Evidence of mediastinal hematoma is suggestive for possible rapid evolution.     

Is it time for firearm injury to be a separate activation criteria in children? An assessment of penetrating pediatric trauma using need for surgeon presence

BackgroundPenetrating injury independently predicts the need for surgeon presence (NSP) upon arrival. Penetrating injury is often used as a trauma triage indicator, however, it includes a wide range of specific mechanisms of injury. We sought to compare firearm-related and non-firearm related pediatric penetrating injuries with respect to NSP, ISS and mortality.MethodsPatients <18 from the 2016 National Trauma Quality Improvement Program Database were included. Penetrating injury was identified and grouped using ICD-10 mechanism codes into firearm and non-firearm related injury. NSP, ISS, and mortality were compared between the two groups.ResultsA total of 1715 (4.2%) patients with penetrating injury were; 832 firearm-related and 883 non-firearm. No deaths occurred among the non-firearm group compared to 94 (11.3%) among firearm-related patients. Among non-firearm patients, 22.7% had a NSP indicator compared to 51.2% of patients injured by a firearm.ConclusionThere is a significantly higher proportion of severe injury and mortality with firearm penetrating injury when compared to non-firearm pediatric penetrating injury. Consideration should be given to dividing it into firearm and non-firearm penetrating injury.     

Dutch trauma system performance: Are injured patients treated at the right place?

BackgroundThe goal of trauma systems is to match patient care needs to the capabilities of the receiving centre. Severely injured patients have shown better outcomes if treated in a major trauma centre (MTC). We aimed to evaluate patient distribution in the Dutch trauma system. Furthermore, we sought to identify factors associated with the undertriage and transport of severely injured patients (Injury Severity Score (ISS) >15) to the MTC by emergency medical services (EMS).MethodsData on all acute trauma admissions in the Netherlands (2015-2016) were extracted from the Dutch national trauma registry. An ambulance driving time model was applied to calculate MTC transport times and transport times of ISS >15 patients to the closest MTC and non-MTC. A multivariable logistic regression analysis was performed to identify factors associated with ISS >15 patients’ EMS undertriage to an MTC.ResultsOf the annual average of 78,123 acute trauma admissions, 4.9% had an ISS >15. The nonseverely injured patients were predominantly treated at non-MTCs (79.2%), and 65.4% of patients with an ISS >15 received primary MTC care. This rate varied across the eleven Dutch trauma networks (36.8%-88.4%) and was correlated with the transport times to an MTC (Pearson correlation -0.753, p=0.007). The trauma networks also differed in the rates of secondary transfers of ISS >15 patients to MTC hospitals (7.8% - 59.3%) and definitive MTC care (43.6% - 93.2%). Factors associated with EMS undertriage of ISS >15 patients to the MTC were female sex, older age, severe thoracic and abdominal injury, and longer additional EMS transport times.ConclusionsApproximately one-third of all severely injured patients in the Netherlands are not initially treated at an MTC. Special attention needs to be directed to identifying patient groups with a high risk of undertriage. Furthermore, resources to overcome longer transport times to an MTC, including the availability of ambulance and helicopter services, may improve direct MTC care and result in a decrease in the variation of the undertriage of severely injured patients to MTCs among the Dutch trauma networks. Furthermore, attention needs to be directed to improving primary triage guidelines and instituting uniform interfacility transfer agreements.     

Cost-Drivers in Acute Treatment of Severe Trauma in Europe: A Systematic Review of Literature

Abstract Introduction:   Throughout the world, trauma is a leading cause of morbidity and mortality in the young and most active group of society. While specialist trauma centers play a critical role in the survival after severe trauma, the assessment of trauma-related costs, budgeting for adequate trauma capacity, and determining the cost-effectiveness of interventions in critical care are fraught with difficulties. Through a systematic review of the European literature on severe trauma, we aimed to identify the key elements that drive the costs of acute trauma care. Methods:   A PubMed/MEDLINE search for articles relating the costs and economics of trauma was performed for the period January 1995 to July 2007. One hundred and seventy-three European publications were identified. Twelve publications were retrieved for complete review that provided original cost data, a breakdown of costs according to the different elements of trauma care, and focused on severe adult polytrauma. The identified publications presented studies from the UK (3), Germany (6), Italy (2), and Switzerland (1). Results:   In all publications reviewed, length of stay in the intensive care unit (ICU; 60%) and requirements for surgical interventions (≤ 25%) were the key drivers of hospital costs. The cost of transfusion during the initial rescue therapy can also be substantial, and in fact represented a significant portion of the overall cost of emergency and ICU care. Multiple injuries often require multiple surgical interventions, and prolonged ICU and hospital stay, and across all studies a clear relationship was observed between the severity of polytrauma injuries observed and overall treatment costs. While significant differences existed in the absolute costs of trauma care across countries, the key drivers of costs were remarkably similar. Conclusions:   Irrespective of the idiosyncrasies of the national healthcare systems in Europe, severity of injury, length of stay in ICU, surgical interventions and transfusion requirements represent the key drivers of acute trauma care for severe injury.     

Does operative treatment of geriatric pelvic ring injuries lead to a high risk of one-year mortality?

IntroductionNon-operative management of pelvic ring injuries in the elderly is associated with a high risk of one-year mortality. The majority of these injuries are the result of a low-energy mechanism, however, due to the multiple medical comorbidities in this patient population the injuries are associated with a high degree of morbidity. The purpose of this study was to determine the one-year mortality risk after operative treatment of pelvic ring injuries in a geriatric patient population and the effect of patient and injury characteristics on the risk of mortality.Patients and methodsWe performed a retrospective review of patients over the age of 70 who underwent operative fixation of a pelvic ring injury at two Level 1 trauma centers between January 2016 and June 2019. Medical records were reviewed for patient and injury characteristics including: Charlson Comorbidity Index (CCI), American Society of Anesthesiologists (ASA) physical status score or Injury Severity Score (ISS), hospital and intensive care unit (ICU) length of stay (LOS). The primary outcome of interest was the one-year mortality risk following operative treatment. Secondary outcomes included the effect of patient and injury characteristics on the one-year mortality risk and the hospital LOS.ResultsNinety patients were included with an average age of 79.8  ±  6.5 years. The overall mortality was 8.9% (n = 8) and was significantly associated with the CCI. There was no significant effect related to the ASA physical status score or ISS. The average hospital LOS was 9.2 ± 7.3 days and was associated with the CCI, ASA physical status score, and ISS.DiscussionNon-operative management of pelvic ring injuries in geriatric patients is associated with a high risk of one-year mortality. Our findings suggest operative treatment of these fractures is associated with an acceptable risk of one-year mortality that falls below the commonly reported range for non-operatively managed injuries. Furthermore, the risk of mortality was significantly associated with the patient's pre-injury state as determined by the CCI.     

Low probability of Significant Intra-Abdominal Injury in Stable Patients with Abdominal ‘‘Seat Belt Sign’’

Abstract Study Objective:   Our aim was to determine the diagnostic significance of the association between the abdominal skin bruise from a seat belt and the presence of intraabdominal injury. Methods:   This was an observational analysis of prospectively collected data on 45 patients who presented with an abdominal seat belt sign to a level 1 trauma center following a motor vehicle accident between July 2004 and December 2007. The patients were evaluated by computed tomography (CT) scans or ultrasonography (FAST), depending on their hemodynamic stability. They were then hospitalized for treatment or observation. Results:   Forty-five patients [23 males (51.1%) and 22 females (48.9%)], with a mean age of 32.2 years (range 16–80 years), fulfilled entry criteria and were enrolled. Of these, 44 (97.8%) underwent CT, and one (2.2%) underwent FAST due to hemodynamic instability. two patients (4.4%) had intraabdominal injuries: one required surgery for bowel injury, and the other had a minor liver laceration, which was managed expectantly. Sixteen patients (35.5%) had concomitant injuries. The length of hospital stay ranged from 1–23 days (median 2.2 days). Conclusions:   Despite the widely accepted view that patients with an abdominal seat belt sign are more likely to have serious intraabdominal injuries, the results of our investigation showed no such association in a group of hemodynamically stable patients.
