Independent Predictors of Mortality in Torso Trauma Injuries

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.

BackgroundThe risk of death and complications after major trauma in patients with chronic kidney disease (CKD) is higher than in the general population, but whether this association holds true among Canadian trauma patients is unknown.ObjectivesTo characterize patients with CKD/receiving dialysis within a regional major trauma cohort and compare their outcomes with patients without CKD.MethodsAll major traumas requiring hospitalization between 2006 and 2017 were identified from a provincial trauma registry in Nova Scotia, Canada. Trauma patients with stage ≥3 CKD (estimated glomerular filtration rate <60 mL/min/1.73 m2) or receiving dialysis were identified by cross-referencing two regional databases for nephrology clinics and dialysis treatments. The primary outcome was in-hospital mortality; secondary outcomes included hospital/intensive care unit (ICU) length of stay (LOS) and ventilator-days. Cox regression was used to adjust for the effects of patient characteristics on in-hospital mortality.ResultsIn total, 6237 trauma patients were identified, of whom 4997 lived within the regional nephrology catchment area. CKD/dialysis trauma patients (n=101; 28 on dialysis) were older than patients without CKD (n=4896), with higher rates of hypertension, diabetes, and cardiovascular disease, and had increased risk of in-hospital mortality (31% vs 11%, p<0.001). No differences were observed in injury severity, ICU LOS, or ventilator-days. After adjustment for age, sex, and injury severity, the HR for in-hospital mortality was 1.90 (95% CI 1.33 to 2.70) for CKD/dialysis compared with patients without CKD.ConclusionIndependent of injury severity, patients without CKD/dialysis have significantly increased risk of in-hospital mortality after major trauma.

Objective: Previous studies looking at emergency department (ED) crowding and delays of care on outcome measures for certain medical and surgical patients excluded trauma patients. The objectives of this study were to assess the relationship of trauma patients’ ED length of stay (EDLOS) on hospital length of stay (HLOS) and on mortality; and to examine the association of ED and hospital capacity on EDLOS.Methods: This was a retrospective database review of Level 1 and 2 trauma patients at a single site Level 1 Trauma Center in the Midwest over a one year period. Out of a sample of 1,492, there were 1,207 patients in the analysis after exclusions. The main outcome was the difference in hospital mortality by EDLOS group (short was less than 4 hours vs. long, greater than 4 hours). HLOS was compared by EDLOS group, stratified by Trauma Injury Severity Score (TRISS) category (< 0.5, 0.51-0.89, > 0.9) to describe the association between ED and hospital capacity on EDLOS.Results: There was no significant difference in mortality by EDLOS (4.8% short and 4% long, p = .5). There was no significant difference in HLOS between EDLOS, when adjusted for TRISS. ED census did not affect EDLOS (p = .59), however; EDLOS was longer when the percentage of staffed hospital beds available was lower (p < .001).Conclusions: While hospital overcrowding did increase EDLOS, there was no association between EDLOS and mortality or HLOS in leveled trauma patients at this institution.

Objectives: Traumatic pneumothorax is one of the causes of trauma mortality and morbidity. It is a problem for developing countries as many accidents can be avoided and there are few epidemiological data to support programs injury prevention. The main objective of the current study was to determine demographic characteristics, patterns, and severity of the injury, thoracic, and extra-thoracic related injuries in a Level 1 trauma center, Riyadh, Saudi Arabia (SA). Methods: This retrospective observational study used the King Abdulaziz Medical City Trauma Center’s trauma registry to review the data of traumatic pneumothorax patients admitted to the hospital from January 2001 to December 2018. Demographic characteristics, admission date and time, type and mechanism of injury, involved body area, and severity rates were analyzed. Results: A total of 708 patients of whom 92.3% were males. Blunt trauma (75.8%) is the most common cause of injury. Motor Vehicle Accidents (MVA) were the most common cause (57%) of traumatic pneumothorax. Rib fractures (36.5%), lung contusions (31.5%), and hemothorax (23.5%) were the most common clinical forms of chest injury associated with traumatic pneumothorax. On the other hand, the head injury (34.8%) was the most common extra thoracic part associated. The mean Injury Severity Score in the current study was found to be 20.1. Conclusion: This study showed the trends of traumatic pneumothorax injuries in a Level 1 trauma center, Riyadh, SA, showing MVA are the leading cause of traumatic pneumothorax in our region. These demographic data will be crucial for local health-care systems to be optimally resourced.

BACKGROUND: As the mean age of the US population increases, so does the incidence of geriatric trauma. Investigators have shown that the elderly have high morbidity and mortality rates associated with traumatic injuries. OBJECTIVE: To compare the severity of injury, mortality, and functional outcomes of geriatric patients with younger patients admitted to a suburban trauma center. METHOD: A convenience sample of trauma patients who were 65 years old or older was compared with trauma patients who were 35 to 45 and 55 to 64 years old. Demographic data, injury data, Injury Severity Scores, Revised Trauma Scores, length of stay, and functional ability outcomes were abstracted from a trauma registry in aggregate form and then analyzed. RESULTS: The sample consisted of 766 subjects (age 35-45, n = 223; age 55-64, n = 135; age 65 and older, n = 408) with a mean age of 64.6 years. A larger percentage of the elderly were victims of falls; younger trauma patients were more likely to be victims of motor vehicle crashes. Significant differences were found between age groups on Glasgow Coma Scale scores. Revised Trauma Scores, and length of stay. Significant differences were not found on Injury Severity Scores, mortality rates, or functional outcomes. CONCLUSIONS: Although anatomic injury severity of elderly patients was similar to that of younger patients, the elderly demonstrated greater physiologic compromise and longer hospital stays. Mortality rates were lower for the elderly group, but this result might be because a larger proportion of elderly patients were hospitalized with minor or moderate injuries.

Level 1 Trauma Center

Transfer of severely injured patients to regional trauma centers is often expedited; however, transfer of less-injured, older patients may not evoke the same urgency. We examined referring hospitals’ length of stay (LOS) and compared the subsequent outcomes in less-injured transfer patients (TP) with patients presenting directly (DP) to the trauma center. We reviewed the medical records of less-injured (Injury Severity Score [ISS] 9 or less), older (age older than 60 years) patients transferred to a regional Level 1 trauma center to determine the referring facility LOS, demographics, and injury information. Outcomes of the TP were then compared with similarly injured DP using local trauma registry data. In 2011, there were 1657 transfers; the referring facility LOS averaged greater than 3 hours. In the less-injured patients (ISS 9 or less), the average referring facility LOS was 3 hours 20 minutes compared with 2 hours 24 minutes in more severely injured patients (ISS 25 or greater, P < 0.05). The mortality was significantly lower in the DP patients (5.8% TP vs 2.6% DP, P = 0.035). Delays in transfer of less-injured, older trauma patients can result in poor outcomes including increased mortality. Geographic challenges do not allow for every patient to be transported directly to a trauma center. As a result, we propose further outreach efforts to identify potential causes for delay and to promote compliance with regional referral guidelines.

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.

IntroductionWith the current need for effective trauma center utilization, understanding how current trauma triage criteria may promote overtriage will enable both field and hospital teams to provide the most appropriate patient care. It is hypothesized that current Southwest Texas trauma criteria promote overtriage by prehospital emergency medical services (EMS) of patients in favor of a Level 1 trauma facility when compared to physician assessment and Injury Severity Score (ISS).MethodsThis prospective, observational study at a Southwest Texas military Level 1 trauma center compared adult trauma patients' prehospital status noted by EMS personnel with the triage criteria documented by the treating emergency physician. The patients were divided into four groups: Prehospital Criteria Met or Not Met; Arrival Criteria Met or Not Met. Each patient's ISS and mechanism of injury were also collected and compared to initial assessment for predictive value. Descriptive statistics were used.ResultsThe study enrolled 278 adult trauma patients. EMS reported Level 1 trauma status similar to physician assessment (60.1% vs. 59.7%, respectively). The rates patients met Level 1 trauma status corresponded with trauma severity when compared to the ISS. Assessment between EMS and physicians for ISSs were similar among the four groups. Comparisons using multivariate analysis of the four groups found similar ISSs, except for the Prehospital Criteria Met/Arrival Criteria Not Met group. Seventy-five percent of these patients were assigned an ISS in the Minor (ISS < 9) category (p = 0.013).ConclusionTrauma triage criteria assessment skills were similar between EMS personnel and emergency physicians except for identifying minor trauma patients. While the criteria generally led to overtriage, EMS crews appear to overtriage minor trauma patients at a much higher rate.

Level 1 Trauma Center

The population of the United States is predicted to age dramatically over the next few decades; as such older patients will comprise an increasing proportion of the injured populations. Due to multiple comorbidities and frailty, the old and very old are at greater risk for mortality than younger patients. To identify predictors of inhospital mortality in these patients, we performed a retrospective cohort study at our Level 1 trauma center. Between April 2009 and October 2014, we identified 193 trauma patients aged 80 years and older admitted to the intensive care unit. The mean age was 86 years old (4.9) and a majority of patients were white (57%) and male (54%). Univariate analysis found Injury Severity Score ( P < 0.01), initial Glasgow Coma Scale ( P < 0.01), admission pH ( P = <0.01), admission lactate ( P < 0.01), the need for mechanical ventilation ( P < 0.01), and Geriatric Trauma Outcome Score ( P < 0.01) to be predictors of mortality. Multivariate analysis identified length of mechanical ventilation [odds ratio (OR) = 0.73, 95% confidence interval (CI) = 0.60–0.90, P < 0.01], admission lactate (OR = 1.74, 95% CI = 1.21–2.51, P < 0.01), and the need for mechanical ventilation (OR = 18.2, 95% CI = 3.33–99.8, P < 0.01) as independent predictors of mortality. These predictors can help guide clinical decisions and should prompt early discussion of goals of care. The association between mechanical ventilation and mortality is confounded by withdrawal of care.

It is presumed that as the number of gunshot wounds (GSWs) increases, so do the Injury Severity Score (ISS) and mortality risk. We hypothesized that the number of bullet wounds relates to ISS and death; however, a single GSW to the head is ominous. We reviewed the charts of all GSW patients admitted to a trauma center from 2004 to 2006 (n = 531). We analyzed patient demographics, ISS, and mortality. There was no correlation with the number of GSWs with either ISS or mortality. There was only a 0.3 per cent increased risk of death for each additional GSW ( r2 = 0.12). Patients with a single GSW versus multiple GSWs had no difference in mortality (9.1 vs 8.4%, P = 0.8). A single GSW to the head carried a 50 per cent mortality risk. For those who sustained both head and body GSWs, each additional GSW did not increase mortality ( r2 = 0.007). Our study shows that the number of GSWs has no affect on mortality or ISS. Internal triage and management of gunshot victims should not be affected by the categorization of patients as having a single versus multiple GSWs.

AbstractIntroductionThe aim of this study was to determine the effect of prehospital time and advanced trauma life support interventions for trauma patients transported to an Iranian Trauma Center.MethodsThis study was a retrospective study of trauma victims presenting to a trauma center in central Iran by Emergency Medical Services (EMS) and hospitalized more than 24 hours. Demographic and injury characteristics were obtained, including accident location, damaged organs, injury mechanism, injury severity score, prehospital times (response, scene, and transport), interventions and in-hospital outcome.ResultsTwo thousand patients were studied with an average age of 36.3 (SD = 20.8) years; 83.1% were male. One hundred twenty patients (6.1%) died during hospitalization. The mean response time, at scene time and transport time were 6.6 (SD = 3), 11.1 (SD = 5.2) and 12.8 (SD = 9.4), respectively. There was a significant association of longer transport time to worse outcome (P = .02). There was a trend for patients with transport times >10 minutes to die (OR: 0.8; 95% CI, 0.1-6.59). Advanced Life Support (ALS) interventions were applied for patients with severe injuries (Revised Trauma Score ⩽7) and ALS intervention was associated with more time on scene. There was a positive association of survival with ALS interventions applied in suburban areas (P = .001).ConclusionIn-hospital trauma mortality was more common for patients with severe injuries and long prehospital transport times. While more severely injured patients received ALS interventions and died, these interventions were associated with positive survival trends when conducted in suburban and out-of-city road locations with long transport times.HosseinpourM, ParavarM, MohammadzadehM, MirzadehAS.
