Risk factors for loss to follow-up after traumatic injury: An updated view of a chronic problem

BackgroundLoss to follow-up after traumatic injury occurs at rates of up to 47%. However, the most recent data are over a decade old, and recent changes in traumatic injury patterns necessitate an updated assessment of risk factors for loss to follow-up after trauma. MethodsWe conducted a retrospective chart review of trauma admissions from January 1, 2018 to December 31, 2021. Categorical variables were compared using χ2 analyses, and continuous variables were analyzed using Mann–Whitney Wilcoxon tests. Multivariable logistic regression was used to adjust for relevant factors identified on unadjusted analysis. ResultsAmong 3,034 patients, overall loss to follow-up was 36.9%. Non-White patients, patients who underwent operations or non-surgical procedures, and patients discharged to rehabilitation facilities were more likely to have follow-up appointments within 30 days. Patients with substance use disorder and, among White patients, those with public insurance had higher loss to follow-up rates. Having a follow-up appointment scheduled with a primary care provider was the single most significant factor associated with attending a follow-up appointment. ConclusionSocial determinants of health, such as insurance status and substance use disorder, are associated with loss of follow-up after trauma. Primary care appointments are associated with the highest attendance rates, supporting that all patients should be offered primary care appointments after traumatic injury.

30-Day Mortality among Very Old Patients Admitted to European Intensive Care Units for Major Trauma

Introduction: Cases of major trauma in the very old (over 80 years) are increasingly common in the intensive care unit (ICU). Predicting outcome is challenging in this group of patients as chronological age is a poor marker of health and poor predictor of outcome. Increasingly, decisions are guided by the use of organ dysfunction scores of both acute conditions (e.g., sequential organ failure assessment [SOFA] score) and chronic health issues (e.g., clinical frailty scale [CFS]). Recent work suggests that increased CFS is associated with a worse outcome in elderly major trauma patients. We aimed to test whether this association held true in the very old (over 80) or whether SOFA had a stronger association with 30-day outcome. Methods: Data from the very elderly intensive care patient (VIP)-1 and VIP-2 studies for patients over 80 years old with major trauma admissions were merged. These participants were recruited from 20 countries across Europe. Baseline characteristics, level of care provided, and outcome (ICU and 30-day mortality) were summarised. Uni- and multivariable regression analyses were undertaken to determine associations between CFS and SOFA score in the first 24 h, type of major trauma, and outcomes. Results: Of the 8,062 acute patients recruited to the two VIP studies, 498 patients were admitted to intensive care because of major trauma. Median age was 84 years, median SOFA score was 6 (IQR 3, 9), and median CFS was 3 (IQR 2, 5). Survival for 30 days was 54%. Median and interquartile range of CFS were the same for survivors and non-survivors. In the logistic regression analysis, CFS was not associated with increased mortality. SOFA score (p < 0.001) and trauma with head injury (p < 0.01) were associated with increased mortality. Conclusions: Major trauma admissions in the very old are not uncommon, and 30-day mortality is high. We found that CFS was not a helpful predictor of mortality. SOFA and trauma with head injury were associated with worse outcomes in this patient group.

Hemothorax Due to Transdiaphragmat-ic Liver Penetrating Injury Caused by Broken Knife

Thoracic trauma is one of the most fatal cases of patients admitted to emergency departments. Thoracic trauma occurs in 20–25% of all trauma patients worldwide and is the third cause of trauma-related deaths. Approximately 5% of trauma admissions are liver injuries. In some blunt or penetrating injuries, both intrathoracic and intra-abdominal organs may be injured. It is aimed to present the case of a broken knife entering from the right paravertebral location, causing hemothorax as a result of diaphragm and liver injury without injuring the lungs, due to the importance of the multidisciplinary approach among surgical departments in the study.&#x0D; A 44-year-old male patient was admitted to the emergency department due to penetrating injury. An oblique injury of approximately 5 cm was seen in the posterior part of the right hemithorax. Radiologically, It was detected that the knife, which entered through the 10th intercostal space, was stuck inside and the knife handle was broken. It was observed that the broken blade entered from the paravertebral region, passed into the intrathoracic area, causing hemothorax, and passed from the edge of the inferior vena cava and embedded itself in the liver. Multidisciplinary operation planning was made among the departments. All department surgeons were present in the operating room at the same time. The paravertebral space was assessed and the embedded blade was slowly withdrawn by the neurosurgeon. Explorative laparotomy was done by the general surgeon and gastroenterology surgeon. Transdiaphragmatic injury was evaluated by the thoracic surgeon and major vascular structures were evaluated by the cardiovascular surgeon. In the postoperative period, the patient was discharged on the 5th postoperative day with full recovery without any complications.&#x0D; Penetrating trauma is one of the most fatal cases of patients admitted to emergency departments. In some cases, intrathoracic and intra-abdominal penetrating injury may occur together, rarely from a single entrance location. The timing of critical intervention varies depending on whether the patient's vitals are stable or unstable. If the hemodynamics are stable in penetrating injuries, all affected anatomical structures should be evaluated with radiological examinations. For successful, uncomplicated surgical treatments, controlled techniques, interdepartmental consensus and, when necessary, simultaneous presence of surgeons in the surgery are essential

Falls From Heights: A Retrospective Review of Roof Fall-Related Trauma.

Background Falls from roofs (FFRs), while constituting just a segment of all falls, pose a significant public health issue. They not only impact individuals in their daily lives but also pose an increased risk in the construction field. The consequences of these falls range broadly, from minor bruises to serious harm, potentially leading to chronic disability or fatality. For the general populace, such falls might happen during simple activities like maintenance, with outcomes varying from fractures to critical head or spinal injuries. In construction, where elevated work is the norm, the likelihood and potential severity of falls are significantly greater. Construction workers face the threat of falls regularly, with these mishaps often resulting in enduring disabilities that affect both life quality and work capability. Methodology This study presents data from a trauma registry system, covering trauma admissions from March 31, 2016, to December 27, 2021, at a level 1 trauma center (Desert Regional Medical Center, Palm Springs, CA). During this five-year and eight-month period, a total of 3,148 patients presented to the emergency department after a fall. This study focuses on patients admitted after an FFR. A retrospective analysis of this data showed that out of these 3,148 patients, 75 presented after an FFR. Results In this retrospective analysis of 75 patients presenting to the emergency department after an FFR, the patient profile was predominantly male (70, 93%), with an average age of 51 years. Hospitalization was required for the majority of thepatients (70, 93%), with a third necessitating intensive care unit (ICU) care. The necessity for surgical procedures was high at 57 (76%). Upon discharge, 8 (11%) patients were moved to acute rehabilitation. Injuries to the extremities were most common, accounting for 21% (36) of cases, in contrast to facial injuries at 8% (15). Upper extremity fractures were the most prevalent presenting injury at 31% (50), while lower extremity fractures were the least at 6% (9). The overall Injury Severity Score (ISS) averaged 12, with patients having hospital length of stays (LOSs) over 10 days presenting higher ISS scores (18) compared to those with shorter stays (ISS of 11). There was no significant difference in ISS between patients aged 60 and above compared to younger patients. Conclusions FFRs represent a substantial cause of injury in both the construction industry and residential settings. This study aims to provide an overview and summary of the existing literature on FFRs, present effective fall prevention methods, and underscore the considerable consequences of such injuries on both construction workers and homeowners. Additionally, it includes an analysis of a dataset detailing injuries resulting from roof-related falls, offering a comparison to existing research.

Impact of Referral Guideline Enforcement on Orthopedic and Trauma Admissions at Kenyatta National Teaching and Referral Hospital, Kenya: A Pre-Post Test Design

Background: The suboptimal utilization of tertiary health facilities and inadequate management of referral systems in low- and middle-income countries pose challenges to health system administration, characterized by frequent self-referrals and bypassing of lower-tier health facilities. On July 1, 2021, Kenyatta National Hospital (KNH) implemented referral guidelines, mandating that all admitted patients be referred from lower-tier health facilities, aligning with the KNH legal statute of 1987. This study aimed to evaluate the impact of enforcing referral guidelines on the spatial distribution of orthopedic and trauma admissions at KNH.&#x0D; Methodology: A pre-posttest study design was employed, reviewing a total of 459 and 446 charts in 2021 before and after the enforcement of referral guidelines. Measures of central tendencies and Chi-squared tests were applied, and density plots were generated using Geographic Information System (QGIS 2.18.19) to illustrate the spatial distribution of admissions.&#x0D; Results: of KNH admissions, 85.3% and 79.3% originated from Nairobi County and its environs. Admissions were geographically diverse, with a notable concentration from Nairobi County and its environs. Enforcement of referral guidelines led to a significant decrease in admissions from Nairobi County, dropping from 64.3% to 56.9% (p=0.019). Declines were particularly observed in Kamukunji, Embakasi, and Ruaraka sub-counties, serving as the catchment population for Mama Lucy Kibaki Referral Hospital. Conversely, admissions from Kibra and most of Kajiado County were notable. There was a concurrent increase in admissions from other parts of the country (p = 0.003).&#x0D; Conclusion: Over four-fifths of KNH admissions are from Nairobi County and its environs. The enforcement of referral guidelines resulted in decreased local admissions and an uptick in admissions from other regions in the country.

Patterns of facility and patient related factors to the orthopedic and trauma admissions at the Kenyatta National Hospital: A qualitative assessment.

Inappropriate utilization of higher-level health facilities and ineffective management of the referral processes in resource-limited settings is increasingly becoming a concern in health care management in developing countries. This is characterized by self-referrals and frequent bypassing of nearest health facilities coupled with low formal referral mechanisms. This scenario lends itself to a situation where uncomplicated medical conditions are unnecessarily managed in a high-cost health facility. This situation compromises the ability and capacity of Kenyatta National Hospital (KNH) to function as a tertiary referral health facility as envisioned by Kenya Health Sector Referral Implementation Guidelines of 2014, Kenya 201 constitution and KNH legal statue of 1987. The study objective was to assess the patterns of facility and patient related factors to the orthopaedic and trauma admissions at the KNH. This was a descriptive qualitative study design. The study was conducted amongst the orthopaedic and trauma admission caseload for 2021. Data collection was done through a) data abstraction from 905 patients charts admitted during February to December 2021 and b) 10 (ten) semi-structured interviews with 10 major health facilities that refer to KNH to understand the reasons for referral to KNH. Quantitative data was analysed using Statistical Package for Social Science version 21.0 to calculate the frequency distribution. Qualitative data from the data abstraction and transcripts from the KIIs were analysed using NVivo version 12. The major facility and patient related factors to the orthopaedic and trauma admissions at KNH were inadequate human resource capacity and availability (42.7%), financial constraints (23.3%), inadequate Orthopaedic equipment's and implants availability (20.0%) and inadequate health facility infrastructure (6.3%) while the major patient related factor was patient's preference (23.4%). In conclusion, to decongest KNH requires that the lower-level health facilities need to be better equipped and resourced to handle essential orthopaedic and trauma care.

The association between post-injury chronic physical health conditions, health status, and survival time in people with serious orthopaedic injuries

Background A better understanding of how chronic physical health conditions affect long-term outcomes following injury is essential for quantifying the burden of serious orthopaedic injuries. We aimed to describe the association between the presence of post-injury chronic physical health conditions and (i) the change in health status from before injury to six different follow-up time points after injury; and (ii) survival time. Methods A cohort study was conducted using linked data from the REcovery after Serious Trauma: Outcomes, Resource Use, and Patient Experiences study, the Victorian Registry of Births, Deaths and Marriages (BDM) (2009–2017), the victorian admitted episodes dataset (2009–2017) and the victorian emergency minimum dataset (2009–2017). Adults (≥ 18 years old) with serious orthopaedic injuries who survived to discharge from their trauma admission were included. Multivariable linear regression analysis was conducted to evaluate the association between post-injury chronic physical health conditions and the mean change in health status (EuroQol-Visual Analogue Scale) from before injury to six follow-up time points post-injury. Survival analysis was conducted to estimate the probability of survival for people with and without chronic physical health conditions following injury. Results Out of 894 participants, 177 (19.8%) had at least one chronic physical health condition recorded up to five years post-injury. People with post-injury conditions reported a greater mean decline in health status than people without post-injury conditions (difference, (95% CI): −6.9 (−9.7, −4.2), p = 0.01). Over the study period, almost six times as many people with chronic physical health conditions post-injury died as people without these conditions (AHR (95% CI): 5.7 (2.9, 11.3), p &lt; 0.01). Conclusions Chronic physical conditions after serious orthopaedic injuries were associated with a lower survival probability and a deteriorating health status. Orthopaedic injury survivors may benefit from early detection and treatment of chronic conditions.

UNNECESSARY PRETRANSFUSION BLOOD SAMPLING IN TRAUMA AND ORTHOPAEDICS IN WALES: A SUSTAINABILITY ISSUE AND FINANCIAL BURDEN

BACKGROUNDTheatre-listed trauma patients routinely require two ‘group and save’ blood-bank samples, in case they need perioperative transfusion. The Welsh Blood Service (WBS) need patients to have one recorded sample from any time in the last 10 years. A second sample, to permit cross-matching and blood issuing, must be within 7 days of transfusion (or within 48 hours if the patient is pregnant, or has been transfused within the last 3 months). The approximate cost of processing a sample is £15.00.AIMTo investigate whether routine pretransfusion blood sampling for trauma admissions exceeds requirements.METHODSElectronic records were used to collect pretransfusion sampling data for all adult non-elective trauma patients listed for theatre under a trauma and orthopaedics consultant between 1/1/2023-31/1/2023. Data were collected on unnecessary samples, rejected samples and total excess samples.RESULTS113 patients (mean age[±SD] 64.09[±19.96]) underwent 132 procedures. On average, unnecessary sampling occurred at a rate of 0.48 samples per operation, equating to a cost of £945.00/month. Samples were rejected by the laboratory at a rate of 0.25 samples per operation. Common reasons for rejection were ‘patient date of birth discrepancy’ (between sample and request form), ‘patient address discrepancy’ and ‘signature discrepancy’. Overall, total excessive sampling occurred at a rate of 0.60 samples per operation.CONCLUSIONNearly half of trauma patients undergo unnecessary blood testing in anticipation of potential perioperative transfusion. This has implications for sustainability, financial cost and patient welfare. This signals poor understanding of WBS requirements and is an area that requires improvement.

The impact of perceived injustice on pain and psychological outcomes after traumatic injury: a longitudinal analysis.

Individuals' appraisals regarding the injustice of their pain or physical injury have emerged as a significant risk factor for worse physical and psychological outcomes. Injustice appraisals are defined by perceptions of external blame for pain or injury and viewing pain or injury as a source of irreparable loss. To date, research on the impact of injustice appraisal has been primarily cross sectional, and existing longitudinal studies have examined injustice appraisals at only 2 time points in the context of rehabilitation treatment. This study examined the trajectory of injustice appraisals in 171 patients admitted for traumatic injury at admission, as well as 3, 6, and 12 months after discharge and examined injustice appraisals as a potential moderator of recovery after injury. Findings can be summarized as follows: First, injustice perception was largely stable in the 12 months after hospital discharge. Second, elevated injustice perception was associated with decreased recovery in pain intensity and depressive symptomatology over the study period but did not moderate changes in pain catastrophizing or posttraumatic stress symptomatology over time. This study is the first naturalistic prospective analysis of injustice appraisal following trauma admission within the American healthcare system. Findings indicate that injustice appraisals do not naturally decrease in the aftermath of traumatic injury and may be a risk factor for poorer physical and psychological recovery. Future research should examine additional sociodemographic and psychosocial factors that may contribute to elevated injustice appraisal, as well as ways of addressing the potential deleterious impact of injustice appraisals in treatment settings.

Comparison of Transfer Patterns by Emergency Medical Services in Trauma Patients in a Major U.S. City

Background:Trauma patients are often unable to communicate a preferred destination hospital to EMS due to their injuries and potentially decreased level of consciousness. The destination hospital is thus determined by the EMS team transporting the patient. This study focuses on trauma admissions between Eskenazi and IUH Methodist Hospitals in downtown Indianapolis, both of which are Level 1 trauma centers within one mile of each other. We are interested in identifying differentiating factors between patients that are admitted at these two hospitals, focusing on the injury type as well as the demographic information for each patient, to determine if there are differential transport patterns.&#x0D; Methods:We performed a retrospective analysis of patient charts and transport documentation to determine basic demographic and admission data for each patient. We especially took note of the location of EMS pickup, the facility the patient was taken to, and the stated reasons for taking the patient to that specific facility. A simple Google Maps search allowed us to determine if the patient was taken to the facility closest to them, or not.&#x0D; Results:We found that among the included patients that were not taken to the nearest Level 1 trauma center, a significant majority were taken to Eskenazi rather than Methodist. Among these patients, a majority were minorities, in contrast with demographic makeup of the patients that were admitted to the closest trauma center.&#x0D; Conclusion:This study highlights how complex EMS transfer patterns are based upon diversion, traffic, individual driver preference, and other factors. There is a significant difference in transport patterns between the two hospitals that correlates with a difference in patient demographics.&#x0D; Policy Implications:This data indicates a need to monitor these numbers closely going forward, paying special attention to all possible reasons that could impact to which facility a patient is admitted.

Time and Risk Factors of Trauma-Related Mortality: A 5-Year Retrospective Analysis From a National Level I Trauma Center.

Background: We aimed to analyze in-hospital timing and risk factors for mortality in a level 1 trauma center. Methods: This is a retrospective analysis of all trauma-related mortality between 2013 and 2018. Patients were divided and analyzed based on the time of mortality (early (≤48 h) vs late (>48 h)), and within different age groups. Multivariate regression analysis was performed to predict in-hospital mortality. Results: 8624 trauma admissions and 677 trauma-related deaths occurred (47.7% at the scene and 52.3% in-hospital). Among in-hospital mortality, the majority were males, with a mean age of 35.8 ± 17.2 years. Most deaths occurred within 3-7 days (35%), followed by 33% after 1 week, 20% on the first day, and 12% on the second day of admission. Patients with early mortality were more likely to have a lower Glasgow coma scale, a higher shock index, a higher chest and abdominal abbreviated injury score, and frequently required exploratory laparotomy and massive blood transfusion (P < .005). The injury severity scores and proportions of head injuries were higher in the late mortality group than in the early group. The severity of injuries, blood transfusion, in-hospital complications, and length of intensive care unit stay were comparable among the age groups, whereas mortality was higher in the age group of 19 to 44. The higher proportions of early and late in-hospital deaths were evident in the age group of 24 to 29. In multivariate analysis, the shock index (OR 2.26; 95%CI 1.04-4.925; P = .04) was an independent predictor of early death, whereas head injury was a predictor of late death (OR 4.54; 95%CI 1.92-11.11; P = .001). Conclusion: One-third of trauma-related mortalities occur early after injury. The initial shock index appears to be a reliable hemodynamic indicator for predicting early mortality. Therefore, timely hemostatic resuscitation and appropriate interventions for bleeding control may prevent early mortality.

Descriptive Analysis of Trauma Admission Trends before and during the COVID-19 Pandemic.

Traumatic injuries are a significant global health concern, with profound medical and socioeconomic impacts. This study explores the patterns of trauma-related hospitalizations in the Lublin Province of Poland, with a particular focus on the periods before and during the COVID-19 pandemic. The primary aim of this research was to assess the trends in trauma admissions, the average length of hospital stays, and mortality rates associated with different types of injuries, comparing urban and rural settings over two distinct time periods: 2018-2019 and 2020-2021. This descriptive study analyzed trauma admission data from 35 hospitals in the Lublin Province, as recorded in the National General Hospital Morbidity Study (NGHMS). Patients were classified based on the International Classification of Diseases Revision 10 (ICD-10) codes. The data were compared for two periods: an 11-week span during the initial COVID-19 lockdown in 2020 and the equivalent period in 2019. The study found a decrease in overall trauma admissions during the pandemic years (11,394 in 2020-2021 compared to 17,773 in 2018-2019). Notably, the average length of hospitalization increased during the pandemic, especially in rural areas (from 3.5 days in 2018-2019 to 5.5 days in 2020-2021 for head injuries). Male patients predominantly suffered from trauma, with a notable rise in female admissions for abdominal injuries during the pandemic. The maximal hospitalization days were higher in rural areas for head and neck injuries during the pandemic. The study highlights significant disparities in trauma care between urban and rural areas and between the pre-pandemic and pandemic periods. It underscores the need for healthcare systems to adapt to changing circumstances, particularly in rural settings, and calls for targeted strategies to address the specific challenges faced in trauma care during public health crises.

Investigating Length of Stay Patterns and Its Predictors in the South Wales Trauma Network.

Length of stay (LOS) is frequently employed as a performance metric for trauma care. Following the establishment of the trauma network worldwide, the assessment and prediction of LOS in different levels of trauma centres have been extensively studied. However, assessing the total patient length of stay from a whole trauma network perspective is unclear. The objective of this study was to systematically analyse the overall Length of Stay (LOS) pattern within the SWTN before its establishment and in the immediate time after its foundation and, secondly, to assess the association between relevant impact factors and LOS. A retrospective secondary analysis based on the trauma admission dataset from Trauma Audit and Research Network(TARN) dataset was conducted. The studied sample covered around 18000 patients admitted to trauma centres from South Wales Major trauma network between January 2012 and October 2021. The primary outcome is the total length of stay in the trauma network. Statistical tests were applied to examine the difference between normal and outlier LOS. Data visualisation was utilised to demonstrate the LOS patterns and potential association between LOS and relevant demographic and clinical predictors. The distribution of length of stay in SWTN follows a right-skewed distribution with a median of 10 (IQR, 5-18) and a mean of 15.92 days. There were 1520 patients with outliers for LOS. A significant difference (p¡ 0.05) was found between the normal and outlier groups of LOS based on demographic (age, gender and residential information) and clinical characteristics(ward type, maximum of anatomically-based injury severity score(AIS) and probability of survival). Age group, maximum AIS score on specific injured region, ward type and its interaction effect with the number of admissions may associated with the LOS. Specifically, patients admitted to the geriatric ward exhibited notably prolonged LOS, and individuals with more than 2 admissions to long-term care and recovery-related wards such as neurosurgical rehabilitation, spinal injuries and burns wards also displayed elevated LOS. Our finding supports prior evidence indicating elderly people are vulnerable to longer stays. Moreover, concerning the types of admission wards, patients admitted to rehabilitation wards who underwent more than 2 hospitalisations also faced an increased risk of prolonged stay. Based on these results, policymakers and healthcare providers should contemplate expanding the allocation of medical resources to this demographic to mitigate the length of stay and optimise associated healthcare costs.

Prediction of outcomes of chest trauma using chest trauma scoring system at a rural tertiary health-care facility

Background: In India, trauma is the most common cause of death. The third most common cause of traumatic death is thoracic trauma. Thoracic trauma accounts for 10% of all trauma admissions, and the mortality rate is reported to range from 10% to 60%. Thoracic trauma patients are likely to be assessed and cared for consistently under a well-designed classification system. Aims: This study aims To investigate Chest Trauma Score (CTS)-based prognostic and predictive outcomes following chest trauma in the Indian subpopulation sustaining chest injuries. Setting and Design: This prospective observational study, Department of General Surgery, Uttar Pradesh University of Medical Sciences, Saifai, Etawah, was included a total of 50 individuals with thoracic trauma. Materials and Methods: When a patient is admitted to the emergency department or trauma unit, a complete clinical assessment, detailed history, vital signs, and all appropriate investigations - including chest radiographs, computed tomography, or high-resolution computed tomography (HRCT) chest (if hemodynamics are stable on admission) - are performed. Age, pulmonary contusion (on HRCT chest), number of rib fractures, and presence of bilateral rib fracture were the four factors used to calculate the CTS. Statistical Analysis: Data were expressed as mean (standard deviation) and percentage (%). Chi-square, Student’s t-test, and analysis of variance were used to compare measured variables. Results: The mean pulse rate (beats/min) and respiratory rate (/min) of patients were significantly higher, and systolic blood pressure (mmHg) and diastolic blood pressure (mmHg) were significantly lower in the nonsurvivor group compared with the survivor group. More than 5 rib fractures and intubation were significantly found more in nonsurvivor group. The mean Glasgow Coma Scale (GCS) was significantly decreased in nonsurvivor group (11.67 ± 1.37) as compared to survivor group (14.55 ± 1.13). Conclusion: Traffic accidents were more frequently (60%) responsible for chest trauma. The mean GCS was significantly associated with patient mortality.

Pneumopericardium following severe thoracic trauma

BackgroundTraumatic pneumopericardium (PPC) is a rare clinical entity associated with chest trauma, resulting from a pleuropericardial connection in the presence of a pneumothorax, interstitial air tracking along the pulmonary perivascular sheaths from ruptured alveoli to the pericardium, or direct trachea-bronchial-pericardial communication. Our objectives were to describe the modern management approach to PPC and to identify variables that could improve survival with severe thoracic injury. MethodsWe conducted a retrospective study of the trauma registry between 2015 and 2022 at a Level I verified adult trauma center for all patients with PPC. Demographics, injury patterns, and treatment characteristics were compared between blunt and penetrating trauma. This study focused on the management strategies and the physiologic status regarding PPC and the development of tension physiology. The main outcome measure was operative versus nonoperative management. ResultsOver a seven-year period, there were 46,389 trauma admissions, of which 488 patients had pneumomediastinum. Eighteen patients were identified with PPC at admission. Median age was 39.5 years (range, 18–77 years), predominantly male (n = 16, 89 %), Black (n = 12, 67 %), and the majority from blunt trauma (78 %). Half had subcutaneous emphysema on presentation while 39 % had recognizable pneumomediastinum on chest x-ray. Tube thoracostomy was the most common intervention in this cohort (89 %). Despite tube thoracostomy, tension PPC was observed in three patients, two mandating emergent pericardial windows for progression to tension physiology, and the remaining requiring reconstruction of a blunt tracheal disruption. The majority of PPC patients recovered with expectant management (83 %), and no deaths were directly related to PPC. ConclusionsTraumatic PPC is a rare radiographic finding with the majority successfully managed conservatively in a monitored ICU setting. These patients often have severe thoracic injury with concomitant injuries requiring thoracostomy alone; however, emergent surgical intervention may be required when PPC progresses to tension physiology to improve overall survival.

Multiligament knee injuries. Ten years' experience at a public university, level I Trauma Center.

To describe our institutional experience and results in the surgical management of multiligament knee injuries (MLKI). Retrospective series of MLKI consecutively operated on at a single, level I Trauma Center. Data on patients' baseline characteristics, injuries, treatments, and outcomes were recorded up to one-year follow-up. Recorded outcomes included the Tegner-Lysholm Knee Scoring Scale (TLKSS), return to work, and patient satisfaction. MLKI incidence was 0.03% among 9897 orthopedic trauma admissions. Twenty-four patients of mean age 43.6years were included in analysis. The mean Injury Severity Score was 12.6. Five patients presented with knee dislocations and six had fracture-dislocations, two of them open fractures. There was one popliteal artery injury requiring a bypass and four common peroneal nerve palsies. Staged ligamental reconstruction was performed in all cases. There were seven postoperative complications. The median TLKSS was 80 and, though patient satisfaction was high, and dissatisfaction was largely restricted to recreational activities (only 58.3% satisfied). Seventeen patients returned to their previous employment. We found a high aggregation of fracture-dislocations secondary to road traffic accidents. One in four patients experienced complications, particularly stiffness. Complications were more common in cases involving knee dislocation. Most patients had good functional results, but 25% were unable to return to their previous work, which demonstrates the long-lasting sequelae of this injury.

Development and validation of a pediatric model predicting trauma-related mortality

ObjectivesTo develop a prediction model of mortality in pediatric trauma-based injuries. Our secondary objective was to transform this model into a translational tool for clinical use.Study designA retrospective cohort study of children ≤ 18 years was derived from the National Trauma Data Bank between the years of 2007 to 2015. The goal was to identify clinical or physiologic variables that would serve as predictors for pediatric death. Data was split into a development cohort (80%) to build the model and then tested in an internal validation cohort (20%) and a temporal cohort. The area under the receiver operating characteristic curve (AUC) was assessed for the new model.ResultsIn 693,192 children, the mortality rate was 1.4% (n = 9,785). Most subjects were male (67%), White (65%), and incurred an unintentional injury (92%). The proposed model had an AUC of 96.4% (95% CI: 95.9%-96.9%). In contrast, the Injury Severity Score yielded an AUC of 92.9% (95% CI: 92.2%-93.6%), while the Revised Trauma Score resulted in an AUC of 95.0% (95% CI: 94.4%-95.6%).ConclusionThe TRAGIC + Model (Temperature, Race, Age, GCS, Injury Type, Cardiac-systolic blood pressure + Mechanism of Injury and Sex) is a new pediatric mortality prediction model that leverages variables easily obtained upon trauma admission.

Development and internal validation of a multivariable model for the prediction of the probability of 1-year readmission to the emergency department for acute alcohol intoxication.

To develop and internally validate a multivariable logistic regression model (LRM) for the prediction of the probability of 1-year readmission to the emergency department (ED) in patients with acute alcohol intoxication (AAI). We developed and internally validated the LRM on a previously analyzed retrospective cohort of 3304 patients with AAI admitted to the ED of the Sant'Orsola-Malpighi Hospital (Bologna, Italy). The benchmark LRM employed readmission to the same ED for AAI within 1year as the binary outcome, age as a continuous predictor, and sex, alcohol use disorder, substance use disorder, at least one previous admission for trauma, mental or behavioral disease, and homelessness as the binary predictors. Optimism correction was performed using the bootstrap on 1000 samples without replacement. The benchmark LRM was gradually simplified to get the most parsimonious LRM with similar optimism-corrected overall fit, discrimination and calibration. The 1-year readmission rate was 15.7% (95% CI 14.4-16.9%). A reduced LRM based on sex, age, at least one previous admission for trauma, mental or behavioral disease, and homelessness, performed nearly as well as the benchmark LRM. The reduced LRM had the following optimism-corrected metrics:scaled Brier score 17.0%,C-statistic 0.799 (95% CI 0.778 to 0.821),calibration in the large 0.000 (95% CI -0.099 to 0.099),calibration slope 0.985 (95% CI 0.893 to 1.088),and an acceptably accurate calibration plot. An LRM based on sex, age, at least one previous admission for trauma, mental or behavioral disease, and homelessness can be used to estimate the probability of 1-year readmission to ED for AAI. To begin proving its clinical utility, this LRM should be validated in external cohorts.

Frailty is associated with long-term outcomes in older trauma patients: A prospective cohort study

BackgroundMost major trauma admissions are older adults, many of whom are living with frailty - a recognised risk factor for post-injury mortality. ObjectivesTo describe the effect of frailty, and geriatrician review on mortality up to 4-years after hospitalisation following trauma. MethodsThis prospective cohort study included patients 65 years or older admitted to North Bristol NHS Trusts’ Major Trauma Centre from November 2018 to September 2019. The primary outcome was time-to-mortality, assessed with an adjusted multivariable Cox regression model. Analyses were adjusted for factors known to be associated with mortality including age, sex, comorbidities, injury factors, surgical procedure, and complications. Results573 patients were included: median age was 81 years; 67.5 % were living with frailty (Clinical Frailty Scale, CFS 4–8). Mortality was 45.2 % at the end of the study. Compared to fit patients (CFS 1-2), risk of death increased in those living with very mild frailty (CFS 4; aHR 3.22 [95 % CI 1.53–6.77]), mild frailty (CFS 5; aHR 4.97 [95 % CI 2.40–10.28]), moderate frailty (CFS 6; aHR 5.94 [95 % CI 2.83–12.44]), and moderate to severe frailty (CFS 7–8; aHR 9.63 [95 % CI 4.35–21.32]). Geriatrician review was associated with less mortality (aHR 0.55, 95 % CI 0.38–0.79). ConclusionsFrailty predicts long-term mortality in older trauma. Our findings have implications for clinician-patient discussions of prognosis and therapy goals. Furthermore, our results lend support to the routine provision of geriatrician input in trauma pathways.

Patterns of major trauma admissions to a level 1 trauma centre: A five year database analysis

IntroductionIt is only in recent years that major trauma systems and networks have been operating in the UK. High-quality data is available from the Trauma Audit and Research Network (TARN) database, enabling regional analysis. Our aim was to analyse Trauma Team Activations within the Cheshire and Merseyside major trauma network and discuss the implications of these data on resource allocation, training and trauma prevention. MethodsA retrospective analysis was performed for all patients requiring Trauma Team Activation (TTA) at a category one adult Major Trauma Centre (MTC) who were submitted to the TARN database from the 1st January 2015 to the 1st January 2020.Data collected included the date and time of arrival, location of injury and Injury Severity Score (ISS) in addition to routine demographic data. Dates of major sporting events and school holidays were obtained. Results4811 patients were identified. The median age was 57 years; 65.8 % were male. The mean frequency of TTAs was 18.5 per week. Patterns identified include annual peaks during the summer months, October and December, weekly peaks on Thursdays and Sundays and daily peaks between 16:00 and 23:59 with 45.0 % of TTAs occurring between these hours.There were 5.9 additional TTAs per week during the Isle of Man TT races. The median ISS increased from 14 to 23 for TT race TTAs and from 14 to 36 for Manx Grand Prix TTAs. Those injured during the TT races were twice as likely to require surgery and those injured during the MGP required five additional days in intensive care. School holidays did not independently affect major trauma volumes. ConclusionsMajor trauma in Cheshire and Merseyside did follow distinct patterns according to calendar month, day and time. Major motorsport increased trauma volumes and severity; school holidays did not. Such analysis could enable Major Trauma Centres to tailor the supply of trauma services to meet a predictable local demand for the benefit of our staff and patients.
