Physicians' beliefs and perceived importance of traumatic brain injury-associated agitation in critically ill patients: a survey of Canadian intensivists.

Agitation is a common behavioural problem following traumatic brain injury (TBI). Intensive care unit (ICU) physicians' perspectives regarding TBI-associated agitation are unknown. Our objective was to describe physicians' beliefs and perceived importance of TBI-associated agitation in critically ill patients. Following current standard guidance, we built an electronic, self-administrated, 42-item survey, pretested it for reliability and validity, and distributed it to 219 physicians working in 18 ICU level-1 trauma centres in Canada. We report the results using descriptive statistics. The overall response rate was 93/219 (42%), and 76/93 (82%) respondents completed the full survey. Most respondents were men with ten or more years of experience. Respondents believed that pre-existing dementia (90%) and regular recreational drug use (86%) are risk factors for agitation. Concerning management, 91% believed that the use of physical restraints could worsen agitation, 90% believed that having family at the bedside reduces agitation, and 72% believed that alpha-2 adrenergic agonists are efficacious for managing TBI agitation. Variability was observed in beliefs on epidemiology, sex, gender, age, socioeconomic status, and other pharmacologic options. Respondents considered TBI agitation frequent enough to justify the implementation of management protocols (87%), perceived the current level of clinical evidence on TBI agitation management to be insufficient (84%), and expressed concerns about acute and long-term detrimental outcomes and burden to patients, health care professionals, and relatives (85%). Traumatic brain injury-associated agitation in critically ill patients was perceived as an important issue for most ICU physicians. Physicians agreed on multiple approaches to manage TBI-associated agitation although agreement on epidemiology and risk factors was variable.

Staged treatment of bicondylar tibial plateau fractures: influence of frame configuration and quality of reduction on outcomes.

Despite evolving treatment, the surgical management of high-energy tibial plateau fractures (TPF) remains challenging, associating high rates of complications. In recent decades, staged management has emerged as an encouraging option. The main goal of our study was to evaluate the influence of bridging external fixation (EF) frame configuration and the resultant quality of reduction (QOR) on outcomes after staged-treatment of bicondylar TPF. A retrospective review was conducted of patients with bicondylar TPF treated at our level-I trauma center using a staged-treatment protocol from January 2010 to January 2020. Data on baseline characteristics, injuries, treatments, and clinical/radiological results were collected. The QOR was evaluated on CT images after EF and on plain films after ORIF. Sixty-eight patients were eligible for analysis. By our criteria, QOR was good in 57.4% and 70.6% after EF and ORIF, respectively. A squared EF configuration was associated with superior EF QOR (p = 0.032), while better EF QOR was linked to improved ORIF QOR (p = 0.016). No relationship between ORIF delay and ORIF QOR was identified. Postoperative complications were documented in 19 patients. Average ROM at one-year follow-up was 114.9 ± 12.6°, and non-influenced by anterior femoral pin placement. Staged management of bicondylar TPF resulted in a reasonable rate of complications. A direct relationship between QORs obtained with EF and after ORIF was found. Squared frames were associated with faster and better reductions, regardless of the surgeon's background. Considering our results, we advocate for the wider use of squared EF configurations in these patients.

Outcome Following Intramedullary Nailing of Tibial Diaphyseal Fractures: Suprapatellar Nail Insertion Results in Superior Radiographic Parameters But No Difference in Mid-Term Function.

The primary aim of this study was to compare the radiographic parameters (nail insertion-point accuracy [NIPA] and fracture malalignment) of patients who had undergone tibial intramedullary nailing via the suprapatellar (SP) and infrapatellar (IP) approaches. The secondary aims were to compare clinical outcomes and patient-reported outcomes (PROs) between these approaches. All adult patients with an acute tibial diaphyseal fracture who underwent intramedullary nailing at a single level-I trauma center over a 4-year period (2017 to 2020) were retrospectively identified. The nailing approach (SP or IP) was at the treating surgeon's discretion. Intraoperative and immediate postoperative radiographs were reviewed to assess NIPA (mean distance from the optimal insertion point) and malalignment (≥5°). Medical records and radiographs were reviewed to evaluate the rates of malunion, nonunion, and other postoperative complications. The Oxford and Lysholm Knee Scores (OKS and LKS) and patient satisfaction (0 = completely dissatisfied, 100 = completely satisfied) were obtained via a postal survey at a minimum of 1 year postoperatively. The cohort consisted of 219 consecutive patients (mean age, 48 years [range, 16 to 90 years], 51% [112] male). There were 61 patients (27.9%) in the SP group and 158 (72.1%) in the IP group. The groups did not differ in baseline demographic or injury-related variables. SP nailing was associated with superior coronal NIPA (p < 0.001; 95% confidence interval [CI] for IP versus SP, 1.17 to 3.60 mm) and sagittal NIPA (p < 0.001; 95% CI, 0.23 to 0.97 mm) and with a reduced rate of malalignment (3% [2 of 61] versus 11% [18 of 158] for IP; p = 0.030). PROs were available for 118 of 211 patients (56%; 32 of 58 in the SP group and 86 of 153 in the IP group) at a mean of 3 years (range, 1.2 to 6.5 years). There was no difference between the SP and IP groups in mean OKS (36.5 versus 39.6; p = 0.246), LKS (71.2 versus 73.5; p = 0.696), or satisfaction scores (81.4 versus 79.9; p = 0.725). Compared with IP nailing, SP nailing of tibial shaft fractures was associated with superior NIPA and a reduced rate of intraoperative malalignment but not of malunion at healing. However, the superior NIPA may not be clinically important. Furthermore, there were no differences in PROs at mid-term follow-up. Therapeutic Level III .

Risks of Reoperation in Surgically Treated Fractures of the Proximal Phalanx

The objective of this study was to determine the risk factors and the rate of reoperation after closed reduction percutaneous pinning (CRPP) of isolated closed single-digit proximal phalanx fractures. A retrospective cohort study was conducted for patients who underwent CRPP of non-thumb closed proximal phalanx fractures between 2010 and 2020 at two level-I trauma centers and two community teaching hospitals. Demographics, fracture, and treatment characteristics were collected. The primary outcome measure was reoperation. Secondary outcome measures were complication and reoperation specifically for digital stiffness. Of the 115 patients who underwent surgical treatment, 46 patients (40.0%) had a complication and 13 patients (11.3%) underwent reoperation at a mean of 6.7 months-most of which (84.6%) were for digital stiffness. Surgeons and patients may be aware that CRPP of closed extra-articular proximal phalanx fractures carries considerable rates of complication and reoperation. Therapeutic III.

Factors Associated With Tracheostomy in Ventilated Pediatric Trauma Patients. A National Trauma Database Study.

The purpose of the study was to find the factors that were associated with tracheostomy procedures in ventilated pediatric trauma patients. The Trauma Quality Improvement Program (TQIP) database of the calendar year 2017 through 2019 was accessed for the study. All patients <18years old and who were on mechanical ventilation for more than 96hours were included in the study. Multiple logistic regression analysis was performed to find the factors that were associated with a tracheostomy. Out of 2653 patients, 1907 (71.88%) patients underwent tracheostomy. The patients who underwent tracheostomy had a lower median [IQR] of Glasgow Coma Scale (GCS) (3 [3-8] vs 5 [3-10], P < .001) and had a higher proportion of severe spine injury (On Abbreviated Injury Scale [AIS]≥3) (11.6% vs 8.8%, P = .044) when compared with patients who did not have tracheostomy. Lower GCS scores and severe spine injury were associated with higher odds of tracheostomy, with all P values <.05. Higher proportion of tracheostomy procedures were performed at level I pediatric trauma centers as compared to non-designated pediatric centers (odds ratio [95% CI]: 1.848 [1.524-2.242], P < .001). A lower GCS score, severe spine injury and highest level trauma centers were associated with a tracheostomy.

The Impact of Venous Reconstruction on Finger Replantation Success Rates Based on Level of Injury

The requirement for anatomic venous reconstruction in digit replantation is an ongoing area of research. In this study, we evaluated our institutional experience to study whether replantation success is affected by the presence or absence of vein repair, stratified by the level of injury. A retrospective review was performed at an urban, level-1 trauma center of all single-digit replantations performed in adults from 2012 to 2021. Patient demographics, injury mechanism, level of injury, whether a vein was repaired, and replant survival were recorded. Sixty-seven single replanted digits were included. Patients were, on average, 38 years old, and 94% were men. The most common mechanism of injury was a sharp laceration (81%). The overall survival rates for all replantations were 68.7% (46/67) and 60% (12/20) for distal finger replantation. Patients with digital replantations at Tamai zone III or more proximal exhibited a 1.8 times increase in survival rates when one vein was repaired versus zero veins (84.4% vs 46.7%). Patients with digital replantations at Tamai zones I and II exhibited similar survival rates. Replantations at or proximal to the middle phalanx should be repaired with at least one artery and vein to maximize the chance for success. However, for distal finger replantations, artery-only replantation is a viable option when vein anastomosis is not achievable. Therapeutic IV.

Hospital episode-of-care costs for hip fractures: an activity-based costing analysis.

Despite the large impact of hip fracture care on hospital budgets, accurate episode-of-care costs (EOCC) calculations for this injury remains a challenge. The objective of this article was to assess EOCC for geriatric patients with hip fractures using an activity-based costing methodology and identify intraoperative, perioperative, and patient-specific factors associated with higher EOCC. This is a retrospective cohort study involving a total of 109 consecutive patients with hip fracture treated surgically at a Canadian level-1 trauma center from April 2018 to February 2019. Clinical and demographic data were extracted through the institution's centralized data warehouse. Data acquisition also included direct and indirect costs per episode of care, adverse events, and precise temporal data. The median total EOCC was $13,113 (interquartile range 6658), excluding physician fees. Out of the total cost, 75% was attributed to direct costs, which represented a median expenditure of $9941. The median indirect cost of the EOCC was $3322. Based on the multivariate analysis, patients not operated within the 48 hours guidelines had an increased length of stay by 5.7 days (P = 0.003), representing an increase in EOCC of close to 5000$. Higher American Society of Anesthesiology (ASA) scores were associated with elevated EOCC. The cost of managing a patient with geriatric hip fracture from arrival in the emergency department to discharge from surgical ward represented $13,113. Main factors influencing the EOCC included adherence to the 48-hour benchmark surgical delay and ASA score. High-quality costing data are vital in assessing health care spending, conducting cost effectiveness analyses, and ultimately in guiding policy decisions. Level III (3), retrospective cohort study.

The Impact of Out-of-Hospital Time and Prehospital Intubation on Return of Spontaneous Circulation following Resuscitative Thoracotomy in Traumatic Cardiac Arrest

Introduction Resuscitative thoracotomy (RT) is a critical procedure performed in certain trauma patients in extremis, with extremely low survival rates. Currently, there is a paucity of data pertaining to prehospital variables and their predictive role in survival outcomes in traumatic cardiac arrest (TCA) patients requiring RT. The aim of the study was to determine the impact of prehospital intubation and out-of-hospital time (OOHT) on return of spontaneous circulation (ROSC) and survival in TCA requiring RT. Methods This was a retrospective cohort study of trauma patients presenting to two level-1 trauma centers, St. Michael’s Hospital and Sunnybrook Health Sciences Center, in Toronto, Canada (January 1, 2005-December 31, 2020). Our exposures of interest were any prehospital intubation attempt and OOHT. Primary and secondary outcome measures were ROSC post-RT and survival to hospital discharge, respectively, and data analysis was performed using univariate logistic regression. Results A total of 195 patients were included, of which 86% were male, and the mean age was 33 years. ROSC and survival to hospital discharge were achieved in 30% and 5% of patients, respectively. Of those who survived to discharge, 89% sustained penetrating trauma. There was no association between OOHT and ROSC (OR = 1.00, 95% CI 0.97–1.03) or survival (OR = 0.99, 95% CI 0.94–1.05). The odds of ROSC were lower in penetrating trauma in the presence of any prehospital intubation attempt (OR = 0.39, 95% CI 0.19–0.82, p = 0.01). ROSC was less likely among all patients with no prehospital signs of life (SOL) compared to those who had prehospital SOL (OR = 0.30, 95% CI 0.13–0.69, p < 0.01). Conclusions There was a significant association between prehospital intubation and lower likelihoods of ROSC in the penetrating TCA population requiring RT, as well as with the absence of prehospital SOL in all patients. OOHT did not appear to significantly impact ROSC or survival.

Epidemiological trends and mid-term to long-term outcomes of acetabular fractures in the elderly in China

PurposeTo explore the epidemiological trends in acetabular fracture and report the mid-term to long-term clinical outcomes of the elderly treated with operation.MethodsRetrospective study. Patients aged ≥ 14 years with operative treatment of the Acetabular fracture from Jan 2010 to Dec 2019 at a level-1 trauma centre were identified to analyze the epidemiological trends, and the difference in fracture patterns between young and elderly patients (≥ 60 years old) were compared. The elderly patients were followed up to evaluate their clinical outcomes and satisfaction degree (worst to best: 0 to10). The patients were divided into the 2010–2014 group and the 2015–2019 group according to the year of admission, and the clinical outcomes of the two groups were compared to verify the stability from mid-term to long-term after surgery for acetabular fracture.ResultsA total of 1024 patients (mean age 43.35 years, range 14–86 years) with acetabular fractures received operative treatment in this decade. The mean age of the acetabular fracture patients increased from 41.1 years to 47.7 years, and the proportion of elderly patients increased from 5.7% to 24.0%, with some volatility. The ratio of male to female decreased year by year, and the proportion of female patients increased with age. And the anterior fracture patterns were more common in the elderly patients compared to the young patients (P < 0.001). 118 elderly patients (82 males, 36 females; mean age 66.91 years, range 60–86 years) were followed-up (mean 77.4 months, range 35–152 months). The overall mortality rate of the elderly patients was 7.69% (9/118). The Harris hip score of those alive patients was 90.41 ± 12.91 points (excellent and good rate 84.4%). 87 patients completed the SF-12 with a normal HRQoL (PCS 50.49 ± 8.88 points; MCS 55.66 ± 8.86 points). 90.8% of the patients achieved a satisfaction score of 9 or higher. And there was no significant difference in clinical outcomes between the 2010–2014 group and the 2015–2019 group (P > 0.05).ConclusionsIn conclusion, acetabular fractures presented an obvious ageing trend in China, and the fracture patterns of the elderly patients differed from those in the young patients. Operative treatment for elderly acetabular fractures yielded satisfactory and persistent clinical outcomes from mid-term to long-term clinical.

Pre-injury sarcopenia and the association with discharge destination in critical care trauma patients

Background Sarcopenia is a key physical component in the aetiology of frailty, representing progressive and CT-quantifiable muscle mass loss. In older trauma patients admitted to critical care, sarcopenic defined-frailty is associated with adverse outcomes, including poor function at discharge. This may complicate discharge to the usual place of residence, an important outcome for patients. This study aimed to identify pre-injury sarcopenia in all trauma patients admitted to critical care and investigate factors associated with discharge destination. Methods We performed a retrospective analysis of adult trauma patients admitted to a Major Trauma Centre (Level 1 equivalent) over 18 months. Psoas muscle density (PMD) was measured at the level of L4 vertebra from admission computerised tomography (CT) abdomen/pelvis. Sarcopenia was defined as the PMD calculated using Hounsfield unit average calculation within the lowest quartile for sex. Discharge destination was dichotomised into independent and dependent discharge. Multivariable logistic regression was used to determine factors associated with discharge destination. Results Overall, 197 patients were included. Patients were predominantly male (73%) with a median age of 52 (32–72) and the majority were severely injured (72%). Sarcopenia was identified in a quarter of the cohort on admission to critical care ( n = 49). Only a third of sarcopenic patients were discharged to home, compared to a half of non-sarcopenic patients ( p = 0.03). Sarcopenia (OR 0.30; 95% CI 0.17–0.81, p = 0.01), blunt injury (OR 0.22; 95% CI 0.06–0.87, p = 0.03), age (OR 0.97; 95% CI 0.95–0.99, p = 0.01) and Multiple Organ Dysfunction Syndrome (OR 0.24; 95% CI 0.12–0.57, p = 0.01) were associated with a decreased rate of independent discharge. Conclusion For trauma critical care patients, sarcopenia on admission CT was associated with dependent discharge destination and therefore is unfavourable. Defining sarcopenia early in an trauma patients critical care admission may help to identify those at risk of poor outcomes.

The State of the Union: Trauma System Development in the United States.

Injury is both a national and international epidemic that affects people of all age, race, religion, and socioeconomic class. Injury was the fourth leading cause of death in the United States (U.S.) in 2021 and results in an incalculable emotional and financial burden on our society. Despite this, when prevention fails, trauma centers allow communities to prepare to care for the traumatically injured patient. Using lessons learned from the military, trauma care has grown more sophisticated in the last 50 years. In 1966, the first civilian trauma center was established, bringing management of injury into the new age. Now, the American College of Surgeons recognizes 4 levels of trauma centers (I-IV), with select states recognizing Level V trauma centers. The introduction of trauma centers in the U.S. has been proven to reduce morbidity and mortality for the injured patient. However, despite the proven benefits of trauma centers, the U.S. lacks a single, unified, trauma system and instead operates within a "system of systems" creating vast disparities in the level of care that can be received, especially in rural and economically disadvantaged areas. In this review we present the history of trauma system development in the U.S, define the different levels of trauma centers, present evidence that trauma systems and trauma centers improve outcomes, outline the current state of trauma system development in the U.S, and briefly mention some of the current challenges and opportunities in trauma system development in the U.S. today.

Association of Early Dexmedetomidine Utilization With Clinical and Functional Outcomes Following Moderate-Severe Traumatic Brain Injury: A Transforming Clinical Research and Knowledge in Traumatic Brain Injury Study.

To examine early sedation patterns, as well as the association of dexmedetomidine exposure, with clinical and functional outcomes among mechanically ventilated patients with moderate-severe traumatic brain injury (msTBI). Retrospective cohort study with prospectively collected data. Eighteen Level-1 Trauma Centers, United States. Adult (age > 17) patients with msTBI (as defined by Glasgow Coma Scale < 13) who required mechanical ventilation from the Transforming Clinical Research and Knowledge in TBI (TRACK-TBI) study. None. Using propensity-weighted models, we examined the association of early dexmedetomidine exposure (within the first 5 d of ICU admission) with the primary outcome of 6-month Glasgow Outcomes Scale Extended (GOS-E) and the following secondary outcomes: length of hospital stay, hospital mortality, 6-month Disability Rating Scale (DRS), and 6-month mortality. The study population included 352 subjects who required mechanical ventilation within 24 hours of admission. The initial sedative medication was propofol for 240 patients (68%), midazolam for 59 patients (17%), ketamine for 6 patients (2%), dexmedetomidine for 3 patients (1%), and 43 patients (12%) never received continuous sedation. Early dexmedetomidine was administered in 77 of the patients (22%), usually as a second-line agent. Compared with unexposed patients, early dexmedetomidine exposure was not associated with better 6-month GOS-E (weighted odds ratio [OR] = 1.48; 95% CI, 0.98-2.25). Early dexmedetomidine exposure was associated with lower DRS (weighted OR = -3.04; 95% CI, -5.88 to -0.21). In patients requiring ICP monitoring within the first 24 hours of admission, early dexmedetomidine exposure was associated with higher 6-month GOS-E score (OR 2.17; 95% CI, 1.24-3.80), lower DRS score (adjusted mean difference, -5.81; 95% CI, -9.38 to 2.25), and reduced length of hospital stay (hazard ratio = 1.50; 95% CI, 1.02-2.20). Variation exists in early sedation choice among mechanically ventilated patients with msTBI. Early dexmedetomidine exposure was not associated with improved 6-month functional outcomes in the entire population, although may have clinical benefit in patients with indications for ICP monitoring.

National analysis of over and under-triage rates in relation to trauma population risk factors and associated outcomes across various levels trauma centers

IntroductionOver and under-triage represent a misallocation of resources that can affect patient outcomes. The purpose of this study is to evaluate over and under-triage rates in relation to risk factors and associated outcomes of trauma patients nationwide. MethodsA retrospective cohort study using the Trauma Quality Improvement Program from 2017 to 2020. Multivariable regression models were used to assess predictors of over-triage (activation when unnecessary) and under-triage (limited activation when full activation was necessary). Results22.2 % (32,782) of the study population were over-triaged and 20.3 % (29,996) were under-triaged. Most over-triaged patients were Black, with Medicaid, or had a penetrating injury, whereas most under-triaged patients were White, with private/commercial insurance, or had a blunt injury. With covariates adjusted for, Pacific Islander (p = 0.024) and American Indian patients (p = 0.015) were associated with higher odds of over-triage, and Hispanic patients had higher odds of under-triage (p<0.001). Patients with Medicare (p<0.001) had higher odds of over-triage, and patients with private/commercial insurance (p<0.001) had higher odds of under-triage compared to Medicaid patients. Patients in level II (p<0.001) and level III (p<0.001) trauma hospitals were associated with higher odds of over-triage. ConclusionPacific Islander and American Indian patients, Medicare, and level II and III trauma centers are at increased risk of over-triage rates, while Hispanic and privately insured trauma patients had a higher risk for under-triage. Future studies should further investigate factors contributing to poor outcomes linked to under-triage practices and methods to improve consistency and standardization of triage tools across various levels of trauma centers.

Non-compressible truncal and junctional hemorrhage: A retrospective analysis quantifying potential indications for advanced bleeding control in Dutch trauma centers

BackgroundTruncal and junctional hemorrhage is the leading cause of potentially preventable deaths in trauma patients. To reduce this mortality, the application of advanced bleeding control techniques, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), junctional tourniquets, Foley catheters, or hemostatic agents should be optimized. This study aimed to identify trauma patients with non-compressible truncal and junctional hemorrhage (NCTJH) who might benefit from advanced bleeding control techniques during initial trauma care. We hypothesized that there is a substantial cohort of Dutch trauma patients that can possibly benefit from advanced bleeding control techniques. MethodsAdult trauma patients with an Abbreviated Injury Scale ≥3 in the torso, neck, axilla, or groin region, who were presented between January 1st, 2014 and December 31st, 2018 to two Dutch level-1 trauma centers, were identified from the Dutch Trauma Registry. Potential indications for advanced bleeding control in patients with NCTJH were assessed by an expert panel of three trauma surgeons based on injury characteristics, vital signs, response to resuscitation, and received treatment. ResultsIn total, 1719 patients were identified of whom 249 (14.5 %) suffered from NCTJH. In 153 patients (60.6 %), hemorrhagic shock could have been mitigated or prevented with advanced bleeding control techniques. This group was younger and more heavily injured: median age of 40 versus 48 years and median ISS 33 versus 22 as compared to the entire cohort. The mortality rate in these patients was 31.8 %. On average, each of the included level-1 trauma centers treated an NCTJH patient every 24 days in whom a form of advanced bleeding control could have been beneficial. ConclusionsMore than half of included Dutch trauma patients with NCTJH may benefit from in-hospital application of advanced bleeding control techniques, such as REBOA, during initial trauma care. Widespread implementation of these techniques in the Dutch trauma system may contribute to reduction of mortality and morbidity from non-compressible truncal and junctional hemorrhage.

Neural processes of emotional conflict detection and prediction of posttraumatic stress disorder symptom clusters in traumatic injury survivors.

Given the prevalence and significant burden of posttraumatic stress disorder (PTSD), identifying early predictors of symptom development following trauma is critical. PTSD is a heterogeneous disorder comprised of distinct symptom clusters-reexperiencing, avoidance, negative mood, and hyperarousal-that contribute to the broad range of possible symptom profiles. Affective and attentional regulation processes, such as emotional conflict detection, are impaired in individuals with PTSD; however, the neural mechanisms underlying these alterations and their predictive utility for the development of PTSD symptoms remain unclear. Traumatic injury survivors (N = 49) without traumatic brain injury were recruited from the emergency department of an urban, Level-1 trauma center. Within 1 month of trauma exposure, participants completed a well-characterized emotional conflict task during a functional magnetic resonance imaging scan. Participants returned 6-month later for a clinical assessment of PTSD symptoms. Using a region-of-interest mask derived from whole-brain voxelwise analyses during emotional conflict detection (vs. no emotional conflict detection) we examined whether differential neural activity predicted 6-month PTSD symptom cluster severity. Greater activation of the right middle frontal gyrus during emotional conflict detection prospectively predicted lower PTSD avoidance symptom severity 6 months later (above and beyond the effects of self-reported baseline PTSD and depressive symptoms, previous traumatic life events, racial discrimination, age, sex, and injury severity). Neural processes of emotion conflict detection measured in the early aftermath of a potentially traumatic event are useful as predictors for the development of PTSD symptoms.

Transarterial interventions in civilian gunshot wound injury: experience from a level-1 trauma center

PurposeTo assess the effectiveness of trans-arterial vascular interventions in treatment of civilian gunshot wounds (GSW).Materials and methodsA retrospective review was performed at a level-1 trauma center to include 46 consecutive adults admitted due to GSW related hemorrhage and treated with endovascular interventions from July 2018 to July 2022. Patient demographics and procedural metrics were retrieved. Primary outcomes of interest include technical success and in-hospital mortality. Factors of mortality were assessed using a logistic regression model.ResultsTwenty-one patients were brought to the endovascular suite directly (endovascular group) from the trauma bay and 25 patients after treatment in the operating room (OR group). The OR group had higher hemodynamic instability (48.0% vs 19.0%, p = 0.040), lower hemoglobin (12.9 vs 10.1, p = 0.001) and platelet counts (235.2 vs 155.1, p = 0.003), and worse Acute Physiology and Chronic Health Evaluation (APACHE) score (4.1 vs 10.2, p < 0.0001) at the time of initial presentation. Technical success was achieved in all 40 cases in which targeted embolization was attempted (100%). Empiric embolization was performed in 6/46 (13.0%) patients based on computed tomographic angiogram (CTA) and operative findings. Stent-grafts were placed in 3 patients for subclavian artery injuries. Availability of pre-intervention CTA was associated with shorter fluoroscopy time (19.8 ± 12.1 vs 30.7 ± 18.6 min, p = 0.030). A total of 41 patients were discharged in stable condition (89.1%). Hollow organ injury was associated with mortality (p = 0.039).ConclusionEndovascular embolization and stenting were effective in managing hemorrhage due to GSW in a carefully selected population. Hollow organ injury was a statistically significant predictor of mortality. Pre-intervention CTA enabled targeted, shorter and equally effective procedures.

Association of Cerebrovascular Injury and Secondary Vascular Insult With Poor Outcomes After Gunshot Wound to the Head in a Large Civilian Population.

Cerebrovascular injury (CVI) after civilian gunshot wound to the head (GSWH) likely contributes to poor outcomes, but little supporting evidence exists. The purpose of this study was to determine whether intracranial CVI from GSWH and secondary vascular insult (stroke or rehemorrhage) were associated with poor outcomes in a large civilian population. This was a single-institution, retrospective cohort study on patients admitted between January 2014 and July 2022 at a large, metropolitan, level-1 trauma center. Multivariate regression models and propensity score matching were used. A total of 512 civilian patients presented with GSWH, and a cohort of 172 (33.5%) met inclusion criteria, with 143 (83.1%) males and a mean (SD) age of 34.3 (±14.2) years. The incidence of intracranial CVI was 50.6% (87/172 patients), and that of secondary vascular insult was 32.2% (28/172 patients). Bifrontal trajectories (adjusted odds ratio [aOR] 13.11; 95% CI 2.45-70.25; P = .003) and the number of lobes traversed by the projectile (aOR 3.18; CI 1.77-5.71; P < .001) were associated with increased odds of resultant CVI. Patients with CVI suffered higher rate of mortality (34% vs 20%; odds ratio [OR] 2.1; CI 0.78-5.85; P = .015) and were less likely to achieve a good functional outcome with a Glasgow Outcome Score of 4-5 (34% vs 68%; OR 0.24; CI 0.1-0.6; P = .004) at follow-up. Furthermore, patients with CVI and resultant secondary vascular insult had even worse functional outcomes (Glasgow Outcome Score 4-5, 16.7% vs 39.0%; aOR 0.012; CI 0.001-0.169, P = .001). Intracranial CVI from GSWH and associated secondary vascular insult are associated with poor outcomes. Given the high prevalence and potentially reversible nature of these secondary injuries, early screening with vascular imaging and treatment of underlying CVI may prove to be critical to improve outcomes by reducing stroke and rehemorrhage incidence.

The effect of a clock’s presence on trauma resuscitation times in a Dutch level-1 trauma center: a pre–post cohort analysis

PurposeInterventions performed within the first hour after trauma increase survival rates. Literature showed that measuring times can optimize the trauma resuscitation process as time awareness potentially reduces acute care time. This study examined the effect of a digital clock placement on trauma resuscitation times in an academic level-1 trauma center.MethodsA prospective observational pre–post cohort analysis was conducted for six months before and after implementing a visible clock in the trauma resuscitation room, indicating the time passed since starting the in-hospital resuscitation process. Trauma patients (age ≥ 16) presented during weekdays between 9.00 AM and 9.00 PM were included. Time until diagnostics (X-Ray, FAST, or CT scan), time until therapeutic intervention, and total resuscitation time were measured manually with a stopwatch by a researcher in the trauma resuscitation room. Patient characteristics and information regarding trauma- and injury type were collected. Times before and after clock implementation were compared.ResultsIn total, 100 patients were included, 50 patients in each cohort. The median total resuscitation time (including CT scan) was 40.3 min (IQR 23.3) in the cohort without a clock compared to 44.3 (IQR 26.1) minutes in the cohort with a clock. The mean time until the first diagnostic and until the CT scan was 8.3 min (SD 3.1) and 25.5 min (SD 7.1) without a clock compared to 8.6 min (SD 6.5) and 26.6 min (SD 11.5) with a clock. Severely injured patients (Injury Severity Score (ISS) ≥ 16) showed a median resuscitation time in the cohort without a clock (n = 9) of 54.6 min (IQR 50.5) compared to 46.0 min (IQR 21.6) in the cohort with a clock (n = 8).ConclusionThis study found no significant reduction in trauma resuscitation time after clock placement. Nonetheless, the data represent a heterogeneous population, not excluding specific patient categories for whom literature has shown that a short time is essential, such as severely injured patients, might benefit from the presence of a trauma clock. Future research is recommended into resuscitation times of specific patient categories and practices to investigate time awareness.

Perceived occupational stressors among nurses in a level-1 trauma center under normalized COVID-19 epidemic prevention and control in China: A qualitative study

BackgroundNurses in trauma centers encounter emergency patients and are exposed to occupational stressors under normalized pandemic control and prevention. ObjectiveThe objective of this study was to examine the occupational stressors that nurses perceived during the COVID-19 pandemic in a level-1 trauma center in China. MethodsFrom December 2020 to May 2021, a qualitative study was conducted, employing conventional content analysis as the research methodology. A total of twelve nurses were purposefully selected from a trauma center at a major hospital in Beijing to participate in semi-structured interviews (40–50 min’ duration). The data collected in this study were analyzed using the conventional content analysis approach proposed by Graneheim and Lundman. ResultsAfter analyzing the data, two themes emerged: 1) Critical conditions under normalized pandemic prevention and control; 2) Concerns about loved ones and colleagues, along with financial problems. Both these themes further revealed four categories: the complexity and uncertainty of epidemic prevention and health hazards in the former, and concerns for and from families and colleagues, and financial stress in the latter. ConclusionsThe results of this study provide valuable insights into the practical implementation of epidemic prevention and control measures in Chinese trauma centers and shed light on the psychological stress faced by nurses. Improving the tripartite support system of hospital, family, and society, and providing emotional support may help reduce stress among nurses, thereby improving their health and care quality.

Return to Skiing After Tibial Plateau Fracture.

Tibial plateau fractures in skiers are devastating injuries with increasing incidence. Few studies have evaluated patient-reported outcomes and return to skiing after operative fixation of a tibial plateau fracture. To (1) identify demographic factors, fracture characteristics, and patient-reported outcome measures that are associated with return to skiing and (2) characterize changes in skiing performance after operative fixation of a tibial plateau fracture. Case series; Level of evidence, 4. We reviewed all operative tibial plateau fractures performed between 2016 and 2021 at a single level-1 trauma center. Patients with a minimum of 10-month follow-up data were included. Patients who self-identified as skiers or were injured skiing were divided into those who returned to skiing and those who did not postoperatively. Patients were contacted to complete the Patient-Reported Outcomes Measurement Information System-Physical Function domain (PROMIS-PF), the Knee injury and Osteoarthritis Outcome Score-Activities of Living (KOOS-ADL), and a custom return-to-skiing questionnaire. Multivariate logistic regression was performed with sex, injury while skiing, PROMIS-PF, and KOOS-ADL as covariates to evaluate factors predictive of return to skiing. A total of 90 skiers with a mean follow-up of 3.4 ± 1.5 years were included in the analysis. The rate of return to skiing was 45.6% (n = 41). The return cohort was significantly more likely to be men (66% vs 41%; P = .018) and injured while skiing (63% vs 39%; P = .020). In the return cohort, 51.2% returned to skiing 12 months postoperatively. The percentage of patients who self-reported skiing on expert terrain dropped by half from pre- to postinjury (61% vs 29.3%, respectively). Only 78% of return skiers had regained comfort with skiing at the final follow-up. Most patients (65%) felt the hardest aspect of returning to skiing was psychological. In the multivariate regression, the male sex and KOOS-ADL independently predicted return to skiing (P = .006 and P = .028, respectively). Fewer than half of skiers who underwent operative fixation of a tibial plateau fracture could return to skiing at a mean 3-year follow-up. The knee-specific KOOS-ADL outperformed the global PROMIS-PF in predicting a return to skiing.
