Ten-year trends in traumatic injury mechanisms and outcomes: A trauma registry analysis

Epidemiology of Accidental Injuries at Home and Related Risk Factors for Mortality among Older Adults in South Korea: A Retrospective Cohort Study

Background and Objectives: Accidental home injuries among older adults are increasing globally, but reporting is limited. This study aims to establish foundational data for program development and policies to prevent accidental injuries at home in older adults by using data on the occurrence of accidental injuries at home and analyzing the risk factors of mortality due to accidental injuries among adults aged 65 years and older. Materials and Methods: This retrospective study used data from the community-based Severe Trauma Survey in South Korea. This study identified general, injury-related, and treatment-related characteristics of older adults who were transported to the emergency department with accidental injuries at home. Single-variable and multiple logistic regression analyses were used to identify risk factors for mortality after injury. Results: The majority of older adults in this study who experienced accidental injuries at home were aged 75 to 84 (42.8%) and female (52.8%), with 1465 injured from falls and slips (68.0%). Risk factors for mortality included older age (≥85 years) (ORs 2.25, 95% CI 1.47-3.45), male sex (ORs 1.60, 95% CI 1.15-2.20), mechanism of injury (falls or slips vs. contact injury, ORs 6.76, 95% CI 3.39-13.47; airway obstruction vs. contact injury, ORs 13.96, 95% CI 6.35-30.71), higher severity (moderate vs. mild, ORs 2.56, 95% CI 1.45-4.54; severe vs. mild, ORs 12.24, 95% CI 6.48-23.12; very severe vs. mild, ORs 67.95, 95% CI 38.86-118.81), and receiving a blood transfusion (ORs 2.14, 95% CI 1.24-3.67). Conclusions: Based on these findings, the home and community environments where older adults live should be inspected and monitored, and in-home accidental injury prevention strategies should be developed tailored to the characteristics of older adults' risk factors and their injury-related characteristics.

Admission of Upper Extremity Injuries Presenting to the Emergency Department: An NEISS Study

BACKGROUND

Upper extremity injuries account for 36.5% of presentations to the emergency department in the United States. This study seeks to determine current rates of upper extremity injuries that present to the emergency department and the injury characteristics of patients requiring admission.

METHODS

National Electronic Injury Surveillance System was queried for a 10-year period for upper extremity injuries. Further analysis was done to evaluate specific patient demographics, injury characteristics, and mechanisms of injury of those patients who were admitted to the hospital.

RESULTS

Between 2012 and 2021, 39 160 365 persons are estimated to have presented to 100 United States emergency departments for managing upper extremity injuries, accounting for 28.8% of total presentations. A total of 12 662 041 upper extremity patients were pediatric (32.3%). Admissions occurred in 4.6% of presentations. The most common presenting diagnosis was laceration (24.9%), while the most common admission diagnosis was fracture (49.7%). The majority had injuries involving their forearms (19.9%). The most common injury-associated consumer product group was stairs, ramps, landings, and floors at 28.5%. Of the 445 644 patients, those estimated to have been injured by stairs, ramps, landings, and floors adults were 429 435 or 96.4%. The most common injury-associated product in pediatric populations was playground equipment (23.6%), of which 53.7% was from monkey bars and other climbing apparatuses.

CONCLUSION

This study demonstrates an overall increase in admissions for upper extremity injuries in the setting of similar rates of overall upper extremity injuries with fractures and forearm being the most common diagnosis and body part involved, respectively.

Comparison of ultrasonography and conventional radiography in the diagnosis of extremity fractures in the emergency department

Objective: The purpose of the study is to compare the diagnostic accuracy (sensitivity and specificity) of ultrasonography (USG) with that of conventional radiography (CR), the standard imaging modality used to diagnose acute extremities fractures. Materials and Methods: The prospective investigation examined 245 patients with clinical symptoms of an extremity fracture. Radiography (anteroposterior and lateral radiographs for each patient, oblique if necessary) and USG were performed on all participants and compared with all the results. Results: CR verified 98.5% of 132 patients who were determined to have extremities fractures with USG. CR, on the other hand, confirmed 99.1% of 112 patients who were reported to have no extremities fractures by USG. The sensitivity (detection of fractures based on USG of patients with fractures detected based on the CR imaging) was 99.2% (95%CI=95.8-99.9); selectivity (no fracture was detected based on USG of patients with no fracture detected based on the CR imaging) was 98.2% (95%CI=93.8-99.7); the positive predictability was 98.48% (95%CI=94.2-99.6), whereas the negative predictability value was 99.1%(95%CI=94-99.8). Conclusion: USG and CR showed similar diagnostic performances in the diagnosis of extremity fractures. USG can be considered an alternative to CR in the examination of extremity fractures with comparable diagnostic performance.

Validation of the adapted clavien dindo in trauma (ACDiT) scale to grade management related complications at a level I trauma center

Objectives

Complications during trauma management are the main factor responsible for the overall increase in treatment cost. There are very few grading systems to measure the burden of complications in trauma patients. A prospective study was conducted using the Adapted Clavien Dindo in Trauma (ACDiT) scale, with the primary aim of validating it at our center. As a secondary aim, it was also wanted to measure the mortality burden among our admitted patients.

Material and Methods

The study was conducted at a dedicated trauma center. All patients with acute injuries, who were admitted, were included. An initial treatment plan was made within 24 hours of admission. Any deviation from this was recorded and graded according to the ACDiT. The grading was correlated with hospital-free days and ICU-free days within 30 days.

Results

A total of 505 patients were included in this study, with a mean age of 31 years. The most common mechanism of injury was road traffic injury, with a median ISS and NISS of 13 and 14, respectively. Two hundred and forty-eight out of 505 patients had some grade of complication as determined by the ACDiT scale. Hospital-free days (13.5 vs. 25; p <0.001) were significantly lower in patients with complications than those without complications, and so were ICU-free days (29 vs. 30; p <0.001). Significant differences were also observed when comparing mean hospital free and ICU free days across various ACDiT grades. Overall mortality of the population was 8.3 %, the majority of whom were hypotensive on arrival and required ICU care.

Conclusion

We successfully validated the ACDiT scale at our center. We recommend using this scale to objectively measure in-hospital complications and improve trauma management quality. ACDiT scale should be one of the data points in any trauma database/registry.

Mortality from fall: A descriptive analysis of a multicenter Indian trauma registry

INTRODUCTION

Fall is the second most common mechanism of trauma worldwide after road traffic injuries. Data on fall predominantly comes from the high-income countries (HICs) and mostly includes injuries in children and elderly. There are very few studies from low- and middle-income countries(LMICs) that describe fall related injuries other than fragility fractures in elderly. This study describes the profile of poly-trauma patients admitted with a history of 'fall' and assesses the variables associated with mortality.

METHOD

We analyzed data from the 'Towards Improved Trauma Care Outcome' (TITCO) database which prospectively collected data of poly-trauma patients admitted to four major tertiary care hospitals of India between 2013 to 2015. Patients across all age groups admitted to hospital with the history of 'fall'; were included in our study. Single bone fractures were excluded.  The Kaplan Meier survival analysis was used to estimate the survival probability in different age groups.

RESULTS

A total of 3686 patients were included in our study. The median age of the patients was 28 years (IQR: 9, 47) with the majority being males (73.6%). Almost one-third of the patients were within the age group of 0-14 (30.4%). Most of the patients (79.9%) had a diagnosis of traumatic brain injury (TBI). The overall in-hospital mortality was 18% (664), but higher at 39.0% among patients over 65 years of age. Probability of survival decreased with increase of age.

CONCLUSION

Falling from height is a common injury mechanism in India, occurring more in young males and usually associated with TBI. Isolated TBI and TBI associated with other injuries are the main contributors of mortality in fall injuries. Mortality from these injuries increased with age and ISS.

Ten‐year trends of adult trauma patients in Central Denmark Region from 2010 to 2019: A retrospective cohort study

Background

Trauma causes significant economic and societal burdens, and the trauma patient population and their prognosis change over time. This study aims to analyze 10‐year trends of trauma patients at a major trauma center in Central Denmark Region.

Methods

Five thousand three hundred and sixty‐six patients aged ≥16 years with Injury Severity Score (ISS) > 0 admitted by trauma team activation at a major trauma center between January 1, 2010, and December 31, 2019, were included. An annual percent change with a 95% confidence interval was used to estimate trends in the mechanism of injuries. Multiple logistic regression with mortality as the outcome was adjusted for age, sex, and ISS. Admission year was used as continuous variable in logistic regressions.

Results

The median age increased from 37 in 2010 to 49 in 2019, and the proportion of patients aged ≥65 doubled. The annual incidence of minor injuries (ISS 1–15) decreased from 181.3/10⁵ inhabitants in 2010 to 112.7/10⁵ in 2019. Severe injuries (ISS > 15) increased from 10.1/10⁵ inhabitants in 2010 to 13.6/10⁵ in 2019. The proportion of patients with ISS > 15 increased from 18.1% in 2010 to 31.1% in 2019. Multivariable logistic regression indicates lower 30‐day mortality for all trauma patients over the study period when adjusting for age, sex, and ISS (odds ratio: 0.94, 95% CI: 0.90–0.99). The 30‐day mortality for severely injured patients with ISS > 15 seems to decrease during the study period when adjusting for age, sex, and ISS (Odds ratio: 0.92, 95% CI: 0.87–0.97). Fall injuries increased by 4.1% annually (95% CI: 2.3%–6.1%).

Conclusions

Ten‐year trends of trauma patients at a major trauma center show an increasing median age, injury severity, and number of fall injuries. The 30‐day mortality of trauma patients decreased slightly for both minor injuries and severe injuries when adjusting for age, sex, and injury severity.

Characteristics and Outcomes of Critically Ill Trauma Patients in Australia and New Zealand (2005-2017)

OBJECTIVES

To compare the characteristics of adults admitted to the ICU in Australia and New Zealand after trauma with nonelective, nontrauma admissions. To describe trends in hospital mortality and rates of discharge home among these two groups.

DESIGN

Retrospective review (2005-2017) of the Australia and New Zealand Intensive Care Society's Center for Outcome and Resource Evaluation Adult Patient Database.

SETTING

Adult ICUs in Australia and New Zealand.

PATIENTS

Adult (≥17 yr), nonelective, ICU admissions.

INTERVENTION

Observational study.

MEASUREMENTS AND MAIN RESULTS

We compared 77,002 trauma with 741,829 nonelective, nontrauma patients. Trauma patients were younger (49.0 ± 21.6 vs 60.6 ± 18.7 yr; p < 0.0001), predominantly male (73.1% vs 53.9%; p < 0.0001), and more frequently treated in tertiary hospitals (74.7% vs 45.8%; p < 0.0001). The mean age of trauma patients increased over time but was virtually static for nonelective, nontrauma patients (0.72 ± 0.02 yr/yr vs 0.03 ± 0.01 yr/yr; p < 0.0001). Illness severity increased for trauma but fell for nonelective, nontrauma patients (mean Australia and New Zealand risk of death: 0.10% ± 0.02%/yr vs -0.21% ± 0.01%/yr; p < 0.0001). Trauma patients had a lower hospital mortality than nonelective, nontrauma patients (10.0% vs 15.8%; p < 0.0001). Both groups showed an annual decline in the illness severity adjusted odds ratio (odds ratio) of hospital mortality, but this was slower among trauma patients (trauma: odds ratio 0.976/yr [0.968-0.984/yr; p < 0.0001]; nonelective, nontrauma: odds ratio 0.957/yr [0.955-0.959/yr; p < 0.0001]; interaction p < 0.0001). Trauma patients had lower rates of discharge home than nonelective, nontrauma patients (56.7% vs 64.6%; p < 0.0001). There was an annual decline in illness severity adjusted odds ratio of discharge home among trauma patients, whereas nonelective, nontrauma patients displayed an annual increase (trauma: odds ratio 0.986/yr [0.981-0.990/yr; p < 0.0001]; nonelective, nontrauma: odds ratio 1.014/yr [1.012-1.016/yr; p < 0.0001]; interaction: p < 0.0001).

CONCLUSIONS

The age and illness severity of adult ICU trauma patients in Australia and New Zealand has increased over time. Hospital mortality is lower for trauma than other nonelective ICU patients but has fallen more slowly. Trauma patients have become less likely to be discharged home than other nonelective ICU patients.

Epidemiology of trauma admissions in a level 1 trauma center in Northern Italy: a nine-year study

The aim of this study was to analyze the results of 9 years of trauma care and data collection in a level 1 urban trauma center in Northern Italy. Overall, 6065 patients have been included in the study; the number of patients managed yearly has doubled between 2011 and 2019. This rise mostly involved patients with injury severity score (ISS) < 16. Most injuries (94%) were blunt. Road traffic accidents, especially involving motorcycles, were the most common cause of injury. Self-inflicted injuries were responsible for less than 5% of trauma but they were severe in 56% of cases. The median age was 38 and it remained constant over the years; 43% of patients had 14-39 years of age. Different characteristics and patterns of injury were observed for each age group and gender. Males were more likely to be injured in the central years of life while females presented a trimodal pattern in the age distribution. Young adults (14-39 years old) were overall at higher risk of self-harm. Overall mortality was equal to 5.2%. Most deceased were male and ≥ 65 years of age.

An Analysis of Patients Dead on Arrival in the American College of Surgeons Trauma Quality Program Participant Use File Data Set

BACKGROUND

Trauma patient care begins on-scene as field triage and mode of transportation are determinants of patient outcomes. This study evaluates the US national patterns of dead on arrival (DOA) among the trauma population.

METHODS

A cross-sectional review of the American College of Surgeons (ACS) Trauma Quality Program Participant Use File (TQP-PUF) data set (2013-2017) was performed. Trauma patients reported as DOA were stratified by ISS into low (<15), intermediate (15-24), or high (≥25) severity. Each group was then subdivided by patient demographics, mechanism, type of injury, and mode of transportation.

RESULTS

Of the 4 336 816 injury cases in the TQP-PUF data set, 33 199 were DOA (.77%). 77.1% (25 604/33 199) of DOAs were male. In the low-ISS group, .36% (13 272/3 639 811) were DOA; in the intermediate-ISS group, 1.2% (4868/421 994) were DOA; and in the high-ISS group, 5.5% (15 059/275 011) were DOA. Motor vehicle collisions (MVCs) (11 262) and firearms (8894) were the most common injury types, equating to 60.7% of DOAs. Falls accounted for 9.1% of all DOAs. The most common DOA age-group was 18-64 years, followed by ≥65 years.

CONCLUSION

DOA trauma patients are predominately adult men suffering fatal blunt force injuries most frequently via MVC. DOAs are caused by all ranges of injury severity. We recommend further development of prevention programs thereby reducing the prevalence of common traumatic injuries, notably MVC, falls, and firearms to improve survival. Future studies should also investigate the access to and distribution of trauma centers and the role of helicopter, ground, and police transport modalities and transport time on and reducing DOAs and improving trauma patient outcomes.

Ten-Year Trends in Traumatic Cardiac Injury and Outcomes: A Trauma Registry Analysis

BACKGROUND

Cardiac injury is a significant cause of death in patients with traumatic injuries. The Oklahoma Trauma Registry collects data from acute care hospitals in Oklahoma. This study investigated the trends and outcomes of traumatic cardiac injury in Oklahoma over a 10-year period.

METHODS

The Oklahoma Trauma Registry tracks patients with major severity and one of the following criteria: hospital stay 48 hours or longer, death on arrival or in the hospital, hospital transfer, intensive care unit admission, or surgery. Cardiac injuries were identified from data acquired 2005 to 2014. Characteristics, mechanisms of injury, associated injuries, and outcomes were analyzed. Results were further divided into blunt vs penetrating injuries and operative vs nonoperative management.

RESULTS

Of 107,549 patients, 426 patients suffered cardiac injury, and 160 patients suffered penetrating trauma. Commonly associated injuries were rib fractures, pneumothorax, hemothorax, and intraabdominal injuries. Of blunt cardiac injuries, 26.7% had spinal fractures. Operative management occurred in 16.9%. Overall mortality rate was 35.7% (51.9% in penetrating and 26.3% in blunt injuries). Mortality was higher for patients who had operative management but was similar in penetrating and blunt cardiac injury. Over 10 years, the percentage of cardiac injury decreased. However, mortality in patients who suffered a cardiac injury increased, correlating with an increase in proportion of penetrating cardiac injury.

CONCLUSIONS

Traumatic cardiac injury, particularly penetrating injury, continues to be a significant source of mortality. Analysis of state-base trauma registries can identify trends in causes of injury and death, serving as a reference point for quality improvement, therapeutic triage, and preventative action plans.

Post-stroke patients with moderate function have the greatest risk of falls: a National Cohort Study

BACKGROUND

Stroke patients have increased risks of falls. We examined national registry data to evaluate the association between post-stroke functional level and the risk of low falls among post-stroke patients.

METHODS

This retrospective cohort study analyzed data from national registries to examine the risk factors for post-stroke falls. Data for patients who suffered ischemic strokes and survived the index hospital admission was obtained from the Singapore National Stroke Registry and matched to the National Trauma Registry, from 2011 to 2015. The primary outcome measure was a low fall (fall height ≤ 0.5 m). Competing risk analysis was performed to examine the association between functional level (by modified Rankin score [mRS] at discharge) and the risk of subsequent low falls.

RESULTS

In all, 2255 patients who suffered ischemic strokes had recorded mRS. The mean age was 66.6 years and 58.5% were men. By the end of 2015, 54 (2.39%) had a low fall while 93 (4.12%) died. After adjusting for potential confounders, mRS was associated with fall risk with an inverted U-shaped relationship. Compared to patients with a score of zero, the sub-distribution hazard ratio (SHR) increased to a maximum of 3.42 (95%CI:1.21-9.65, p = 0.020) for patients with a score of 2. The SHR then declined to 2.45 (95%CI:0.85-7.12, p = 0.098), 2.86 (95%CI:0.95-8.61, p = 0.062) and 1.93 (95%CI:0.44-8.52, p = 0.38) for patients with scores of 3, 4 and 5 respectively.

CONCLUSIONS

An inverted U-shaped relationship between functional status and fall risk was observed. This is consistent with the complex interplay between decreasing mobility (hence decreased opportunity to fall) and increasing susceptibility to falls. Fall prevention intervention could be targeted accordingly. (263 words).

Fibrinolysis Shutdown in Trauma: Historical Review and Clinical Implications

Despite over a half-century of recognizing fibrinolytic abnormalities after trauma, we remain in our infancy in understanding the underlying mechanisms causing these changes, resulting in ineffective treatment strategies. With the increased utilization of viscoelastic hemostatic assays (VHAs) to measure fibrinolysis in trauma, more questions than answers are emerging. Although it seems certain that low fibrinolytic activity measured by VHA is common after injury and associated with increased mortality, we now recognize subphenotypes within this population and that specific cohorts arise depending on the specific time from injury when samples are collected. Future studies should focus on these subtleties and distinctions, as hypofibrinolysis, acute shutdown, and persistent shutdown appear to represent distinct, unique clinical phenotypes, with different pathophysiology, and warranting different treatment strategies.

Looking for the reason of hemodynamic instability: a case report of the role of intraoperative ultrasound

Background and objectives

A prompt and effective management of trauma patient is necessary. The aim of this case report is to highlight the importance of intraoperative echocardiography as a useful tool in patients suffering from refractory hemodynamic instability no otherwise explained.

Case report

A 41 year-old woman suffered a car accident. At the emergency department, no abnormalities were found in ECG or chest X-ray. Abdominal ultrasound revealed the presence of abdominal free liquid and the patient was submitted to urgent exploratory laparotomy. Nevertheless, she persisted suffering arterial hypotension and metabolic acidosis. Looking for the reason of her hemodynamic instability, intraoperative transthoracic echocardiography was performed, finding out the presence of pericardial effusion. Once the cardiac surgeon extracted pericardial clots, patient's situation improved clinically and analytically.

Conclusion

Every anesthesiologist should be able to use the intraoperative echocardiography as an effective tool in order to establish the appropriate measures to promote the survival of patients suffering severe trauma.

Prehospital treatment of patients with acute intracranial pathology: adherence to guidelines and blood pressure recommendations by the Danish Air Ambulance

Background

Hypoxia and hypotension may be associated with secondary brain injury and negative outcomes in patients with traumatic and non-traumatic intracranial pathology. Guidelines exist only for the prehospital management of patients with severe traumatic brain injury (TBI). In patients with non-traumatic intracranial pathology, TBI guideline recommendations may be applied to assess whether hypoxia and hypotension should be avoided during prehospital treatment. The main study objective was to assess the extent to which Danish Helicopter Emergency Medical Service (HEMS) critical care teams adhere to the prehospital TBI guideline recommendations for the management of patients with a clinical diagnosis of non-traumatic intracranial pathology or isolated TBI. Furthermore, in the same two groups of patients, we evaluated the adherence of the Danish HEMS critical care teams to recommendations aiming to maintain systolic blood pressure (SBP) > 110 mmHg and > 120 mmHg.

Methods

In total, 211 prehospital patient records were studied. All patients were treated for non-traumatic intracranial pathology or isolated TBI by the Danish HEMS critical care teams from October 1, 2014, to January 1, 2017. Adherence to the prehospital TBI guideline recommendations and the SBP recommendations above was assessed in non-TBI and TBI populations.

Results

The adherence rates to TBI guideline recommendations among Danish HEMS critical care teams were 69% (n = 106 [95% CI: 61–77%]) in the non-TBI population and 74% (n = 43 [95% CI: 61–85%]) in the TBI population. SBP > 110 mmHg was observed in 74% (n = 113 [95% CI: 66–81%]) and 69% (n = 40 [95% CI: 56–81%]) of cases in the non-TBI and TBI population, respectively. SBP > 120 mmHg was observed in 55% (n = 84, [95% CI: 47–63%]) of patients in the non-TBI population and 55% (n = 32 [95% CI: 42–68%]) of the patients in the TBI population.

Conclusions

Due to a lack of comparative data, it is difficult to determine the performance quality of the Danish HEMS critical care teams. Our findings may suggest that adherence to TBI guidelines and SBP recommendations needs to be a continuous focal point for the Danish HEMS to avoid secondary brain damage.
