European Burns Association guidelines for the management of burn mass casualty incidents within a European response plan

BackgroundA European response plan to burn mass casualty incidents has been jointly developed by the European Commission and the European Burn Association. Upon request for assistance by an affected country, the plan outlines a mechanism for coordinated international assistance, aiming to alleviate the burden of care in the affected country and to offer adequate specialized care to all patients who can benefit from it. To that aim, Burn Assessment Teams are deployed to assess and triage patients. Their transportation priority recommendations are used to distribute outnumbering burn casualties to foreign burn centers. Following an appropriate medical evacuation, these casualties receive specialized care in those facilities.MethodsThe European Burns Association’s disaster committee developed medical-organizational guidelines to support this European plan. The experts identified fields of interest, defined questions to be addressed, performed relevant literature searches, and added their expertise in burn disaster preparedness and response. Due to the lack of high-level evidence in the available literature, recommendations and specially designed implementation tools were provided from expert opinion. The European Burns Association officially endorsed the draft recommendations in 2019, and the final full text was approved by the EBA executive committee in 2022.RecommendationsThe resulting 46 recommendations address four fields. Field 1 underlines the need for national preparedness plans and the necessary core items within such plans, including coordination and integration with an international response. Field 2 describes Burn Assessment Teams' roles, composition, training requirements, and reporting goals. Field 3 addresses the goals of specialized in-hospital triage, appropriate severity criteria, and their effects on priorities and triage. Finally, field 4 covers medical evacuations, including their timing and organization, the composition of evacuation teams and their assets, preparation, and the principles of en route care.     

Differentiation of confirmed major trauma patients and potential major trauma patients using pre-hospital trauma triage criteria

Background

There is a paucity of literature comparing trauma patients who meet pre-hospital trauma triage guidelines (‘potential major trauma’) with trauma patients who are identified as ‘confirmed major trauma patients’ at hospital discharge. This type of epidemiological surveillance is critical to continuous performance monitoring of mature trauma care systems. The current study aimed to determine if the current trauma triage criteria resulted in under/over-triage and whether the triage criteria were being adhered to.

Methods

For a 12-month time period there were 45,332 adult (≥16 years of age) trauma patients transported by ambulance to hospitals in metropolitan Melbourne. This retrospective study analysed data from 1166 patients identified at hospital discharge as ‘confirmed major trauma patients’ and 16,479 patients captured by the current pre-hospital trauma triage criteria, who did not go on to meet the definition of confirmed major trauma. These patients comprise the ‘potential major trauma’ group. Non-major trauma patients (N = 27,687) were excluded from the study. Pre-hospital data was sourced from the Victorian Ambulance Clinical Information System (VACIS) and hospital data was sourced from the Victorian State Trauma Registry (VSTR). Statistical analyses compared the characteristics of confirmed major trauma and potential major trauma patients according to the current trauma triage criteria.

Results

The leading causes of confirmed major trauma and potential major trauma were motor vehicle collisions (30.1% vs. 19.2%) and falls (30.0% vs. 48.7%). More than 80% of confirmed major trauma and 24.4% of potential major trauma patients were directly transported to a major trauma service. Overall, similar numbers of confirmed major trauma patients and potential major trauma patients had one or more aberrant vital signs (67.0% vs. 66.4%). Specific injuries meeting triage criteria were sustained by 69.2% of confirmed major trauma patients and 51.4% of potential major trauma patients, while 11.7% of confirmed major trauma patients and 4.6% of potential major trauma patients met the combined mechanism of injury criteria.

Conclusions

While the sensitivity of the current pre-hospital trauma triage criteria is high, if paramedics strictly followed the criteria there would be significant over-triage. Triage models using different mechanistic and physiologic criteria should be evaluated.     

Tree-based algorithm for prehospital triage of polytrauma patients

BackgroundThere is a need for better allocation of medical resources in polytrauma, by optimizing both the over and undertriage rates. The goal of this study is to provide a new working definition for polytrauma based on the prediction of the need for specialized trauma care.MethodsThis is a prospective, observational study, performed in a specialized trauma center in Paris. All consecutive patients admitted for a trauma at a major trauma center in Paris were included in the study. The primary outcome was the need for specialized trauma care as defined by the North American consensus. The explanatory variables included basic variables collected on scene. The modeling approach relied on recursive partitioning based decision trees. Its prediction performance was evaluated both internally and externally on a validation cohort, and compared to the MGAP (Mechanism, Glasgow coma scale, Age and Arterial pressure) score.Measurements and main results1160 patients were included in the analysis over a 3-year period (2012–2014), out of which 41% needed specialized trauma care as defined by the recent US guidelines. The decision tree outperformed the MGAP and reached an area under the receiver operating characteristic curve of 0.82 [0.79–0.84]. This optimal decision rule was associated with a sensitivity of 0.94 [0.92–0.96], a specificity of 0.48 [0.44–0.52]. A conservative decision rule (refer to a trauma center all patient with a predicted probability ≥0.34) would result in an undertriage rate of 5.7% and an overtriage of 52.3% (respectively 7% and 64% in the validation cohort).ConclusionsOur tree-based decision algorithm is a user-friendly and reliable alternative to the preexisting scores, which offers good performance to predict the need for specialized trauma care.     

A systematic literature review of criteria and models for casualty distribution in trauma related mass casualty incidents

IntroductionMass casualty incidents impose a large burden on the emergency medical systems, hospitals and community infrastructures. The pre-hospital and hospital capacities are usually bear the burden of casualties large numbers. One of the challenging issues in mass casualty incidents is the distribution of casualties among the suitable health care facilities.ObjectiveTo review models and criteria affecting the distribution of casualties during the trauma-related mass causality incidents.Materials and methodsA systematic literature search in the scientific databases which included: PubMed, Scopus and Web of Science was conducted. Relevant literature which was published before August 2017 was searched. Neither the publication date nor language limitations were considered in the literature search. All the trauma-related mass casualty incidents are included in this study. Two independent reviewers conducted the data extraction and quality assessment of the documents was considered using a checklist developed by the researchers.ResultsLiterature search yielded 4540 documents of which 493 were duplicated and removed. After reviewing the titles and abstracts of the remaining documents (4047), only 73 documents were considered relevant. Finally, the inclusion and exclusion criteria were applied and only 30 documents were considered for data extraction and quality assessment. The study found 491 criteria to be affecting the distribution of casualties following trauma-related mass casualty incidents. These are categorized as pre-hospital (triage, treatment and transport); hospital (space, staff, stuff, system / structure); incidents’ characteristics and others. The criteria which were extracted from the models are termed as “model extracted” while the other labeled as “author suggested”.ConclusionTo the best of our knowledge, this is the first systematic literature review on criteria affecting distribution of casualties following trauma-related mass casualty incidents based on the pre-hospital and hospital capacities.Systematic review registration numberThis review was registered in international prospective register of systematic reviews (PROSPERO) with registration number CRD42016049115.     

Mass casualty incidents with multiple burn victims: Rationale for a Swiss burn plan

Introduction

Mass casualty incidents involving victims with severe burns pose difficult and unique problems for both rescue teams and hospitals. This paper presents an analysis of the published reports with the aim of proposing a rational model for burn rescue and hospital referral for Switzerland.

Methods

Literature review including systematic searches of PubMed/Medline, reference textbooks and journals as well as landmark articles.

Results

Since hospitals have limited surge capacities in the event of burn disasters, a special approach to both prehospital and hospital management of these victims is required. Specialized rescue and care can be adequately met and at all levels of needs by deploying mobile burn teams to the scene. These burn teams can bring needed skills and enhance the efficiency of the classical disaster response teams. Burn teams assist with both primary and secondary triage, contribute to initial patient management and offer advice to non-specialized designated hospitals that provide acute care for burn patients with Total Burn Surface Area (TBSA) <20–30%. The main components required for successful deployments of mobile burn teams include socio-economic feasibility, streamlined logistical implementation as well as partnership coordination with other agencies including subsidiary military resources.

Conclusions

Disaster preparedness plans involving burn specialists dispatched from a referral burn center can upgrade and significantly improve prehospital rescue outcome, initial resuscitation care and help prevent an overload to hospital surge capacities in case of multiple burn victims. This is the rationale behind the ongoing development and implementation of the Swiss burn plan.     

Equestrian injuries: incidence, injury patterns, and risk factors for 10 years of major traumatic injuries

BACKGROUND: Horseback riding is more dangerous than motorcycle riding, skiing, football, and rugby. The purpose of this study was to identify the incidence and injury patterns, as well as risk factors associated with severe equestrian trauma. METHODS: All patients with major equestrian injuries (injury severity score > or = 12) admitted between 1995 and 2005 were reviewed. A 46-question survey outlining potential rider, animal, and environmental risk factors was administered. RESULTS: Among 7941 trauma patients, 151 (2%) were injured on horseback (mean injury severity score, 20; mortality rate, 7%). Injuries included the chest (54%), head (48%), abdomen (22%), and extremities (17%). Forty-five percent required surgery. Survey results (55%) indicated that riders and horses were well trained, with a 47% recidivism rate. Only 9% of patients wore helmets, however, 64% believed the accident was preventable. CONCLUSIONS: Chest trauma previously has been underappreciated. This injury pattern may be a result of significant rider experience. Helmet and vest use will be targeted in future injury prevention strategies.     

The full spectrum of handlebar injuries in children: A decade of experience

Background

Traumatic paediatric handlebar injury (HBI) is known to occur with different vehicles, affect different body regions, and have substantial associated morbidity. However, previous handlebar injury research has focused on the specific combination of abdominal injury and bicycle riding. Our aim was to fully describe the epidemiology and resultant spectrum of injuries caused by a HBI.

Methods

Retrospective data analysis of all paediatric patients (<18 years) in a prospectively identified trauma registry over a 10-year period. Primary outcome was the HBI, its location and management. The effects of patient age, vehicle type, the impact region, and Injury Severity Score (ISS) were also evaluated. HBI patients were compared against a cohort injured while riding similar vehicles, but not having sustained a HBI.

Results

1990 patients were admitted with a handlebar-equipped vehicle trauma; 236 (11.9%) having sustained a HBI. HBI patients were twice as likely to be aged between 6 and 14 years old compared with non-HBI patients (OR 2.2; 95% CI 1.5–3.2). 88.6% of the HBI patients sustained an isolated injury, and 45.3% had non-abdominal handlebar impact. There were no significant differences in median ISS (p = 0.4) or need for operative intervention (OR 1.1; 95% CI 0.9–1.5) between HBI and non-HBI patients. HBI patients had a significantly longer LOS (1.8 days vs. 1.2 days; p = 0.001), and more frequently required a major operation (OR 3.4; 95% CI 2.2–5.4). The majority of splenic, renal and hepatic injuries were managed conservatively.

Conclusions

Although the majority of paediatric HBI is associated with both intra-abdominal injury and bicycle riding, it produces a spectrum of potentially serious injuries and patients are more likely to undergo major surgery. Therefore these patients should always be treated with a high degree of suspicion.     

Qualitative study of health system preparedness for traumatic incidents in a religious mass gathering

Background and ObjectivesTraumatic incidents may occur during religious mass gatherings. A lack of preparedness by the health system to respond to traumatic incidents may increase the mortality rate. This study investigated the factors that affect the preparedness of a health system to respond to traumatic incidents, and we provide appropriate suggestions for improving the response to such incidents during religious mass gatherings.MethodsA qualitative research method was used with a conventional content analysis approach. In total, 22 semi-structured interviews were conducted employing the content analysis method. The data were analyzed based on the means of the meaning units, condensed meaning units, sub-themes, themes, and codes.ResultsFour main categories and nine sub-categories emerged from the data: factors that increased or decreased the occurrence of incidents (with three sub-categories comprising risk perception and fatalism, pilgrims’ responses to incidents, and health system response to traumatic events); medical infrastructure (with two sub-categories comprising medical infrastructure in the host country and medical structures in border cities); organizational resource category (with two sub-categories comprising manpower, and equipment and facilities); and coordination of responsible organizations (with two sub-categories comprising inter-organizational coordination and inter-agency collaboration). All of the data were extracted from the experiences of the participants.ConclusionSimilar to other mass gatherings, Arbaeen requires multi-sectoral and international planning, organizing, and management. The key factors that could improve the preparedness to respond to traumatic events in Arbaeen include training, increasing the perception of risk, changing the attitudes and behavior of pilgrims, developing a national strategic plan of the health system preparedness for policymakers, and implementing scenario-based exercises for executives.     

UK Triage the validation of a new tool to counter an evolving threat

IntroductionMajor Incidents (MI) occur frequently and their unpredictable nature makes prospective research difficult and largely unethical. A key step in MI management is triage; the identification of the critically injured. Within a MI environment this is commonly performed using simple physiological ‘tools’, such as the Triage Sieve (TS). However the most commonly used tools appear to lack an evidence base. In a previous study, the authors used a military population to compare the performance of the TS to the Military Sieve (MS) at predicting need for Life-Saving Intervention (LSI). The MS differs only with the addition of a measurement of consciousness. The outcome from this study was that the MS outperformed the TS, but could be further improved with small changes to its physiological parameters, the Modified Military Sieve (MMS).Materials and MethodsPhysiological data and interventions performed within the Emergency Department (ED) and Operating Theatre were prospectively collected for consecutive adult trauma patients (>18years) presenting to the ED at Camp Bastion, Afghanistan between March and September 2011. All patients receiving a LSI were considered Gold Standard Priority One. Patients were triaged using the TS, MS, MMS, START (ST) and Careflight (CF) triage tools. Sensitivities and specificities were estimated with 95% confidence intervals and differences were checked for statistical significance using a McNemar test with Bonferroni correction.Results482 patients presented to the ED during the study period, sufficient data was recorded for 335 (71%) with 199 (59%) P1s. The MMS (sensitivity 68.3%, specificity 79.4%) showed an absolute increase in sensitivity over existing tools ranging from 5.0% (MS) to 23.6% (CF). There was a statistically significant difference (P = 0.0005) between the MMS and MS.DiscussionA key limitation to this study, is the use of a military cohort to validate the MMS, a tool which itself was developed using military data. The mechanism of injury also is unlikely to translate fully to the civilian population.ConclusionsWithin a military population, the MMS outperforms existing MI triage tools. Before it is recommended as a replacement to the existing TS in UK civilian practice, it needs to be tested in a civilian environment.     

Performance of the modified TRISS for evaluating trauma care in subpopulations: A cohort study

IntroductionPrevious research showed that there is no agreement on a practically applicable model to use in the evaluation of trauma care. A modification of the Trauma and Injury Severity Score (modified TRISS) is used to evaluate trauma care in the Netherlands. The aim of this study was to evaluate the prognostic ability of the modified TRISS and to determine where this model needs improvement for better survival predictions.MethodsPatients were included if they were registered in the Brabant Trauma Registry from 2010 through 2015. Missing values were imputed according to multiple imputation. Subsets were created based on age, length of stay, type of injury and injury severity. Probability of survival was calculated with the modified TRISS. Discrimination was assessed with the Area Under the Receiver Operating Curve (AUROC). Calibration was studied graphically.ResultsThe AUROC was 0.84 (95% CI: 0.83, 0.85) for the total cohort (N = 69 747) but only 0.53 (95% CI: 0.51, 0.56) for elderly patients with hip fracture. Overall, calibration of the modified TRISS was adequate for the total cohort, with an overestimation for elderly patients and an underestimation for patients without brain injury.ConclusionsOutcome comparison conducted with TRISS-based predictions should be interpreted with care. If possible, future research should develop a simple prediction model that has accurate survival prediction in the aging overall trauma population (preferable with patients with hip fracture), with readily available predictors.     

Unwarranted clinical variation in the care of children and young people hospitalised for injury: a population-based cohort study

IntroductionInjury is a leading cause of death and disability among children and young people. Recovery may be negatively affected by unwarranted clinical variation such as representation to an emergency department (ED), readmission to a hospital, and mortality. The aim of this study was to examine unwarranted clinical variation across providers of care of children and young people who were hospitalised for injury in New South Wales (NSW).Materials and MethodsRetrospective population-based cohort study using linked ED, hospital, and mortality data of all children and young people aged ≤25 years who were injured and hospitalised during 1 January 2010–30 June 2014 in NSW. Unwarranted clinical variation across providers was examined using three indicators. That is, for each hospital that treated ≥100 cases per year, risk standardised ratios were calculated with 95% and 99.8% confidence limits using the number of observed and expected events of (1) representations to ED within 72 h, (2) unplanned readmissions to hospital within 28 days, and (3) all-cause mortality within 30 days.ResultsThere were 189,990 injury-related hospitalisations of children and young people. Of these, 4.4% represented to an ED, 8.7% were readmitted to hospital, and 0.2% died. Of the 45 public hospitals that treated ≥100 cases per year, higher than expected rates of ED representations, hospital readmissions, and mortality were observed in eleven, six, and two hospitals, respectively.ConclusionThe rates of ED representations, hospital readmissions, and mortality among children and young people hospitalised for injury in NSW were similar to the rates reported in other countries. However, unwarranted clinical variation across public hospitals was observed for all three indicators. These findings suggest that by improving routine follow-up support services post-discharge for children and young people and their families, it may be possible to reduce unwarranted clinical variation and improve health outcomes.     

Autopsies following death due to traumatic injuries in The Netherlands: an evaluation of current practice

INTRODUCTION: Because of a steady decline in the number of autopsies following death due to traumatic injuries, valuable information concerning possible missed injuries and potential improvements in management is lost. This retrospective study describes current practice in the Amsterdam region of the Netherlands regarding such autopsies, and their rates. METHOD: The current protocols for autopsies were reviewed. Data from government databases and hospitals for the year 2005 were collected. For all patients included that died an unnatural death due to traumatic injury, causes of death and recommendations for autopsy were reviewed. The number of clinical and medico-legal autopsies was determined. RESULTS: Of 872 registered unnatural deaths, 414 were due to traumatic injuries; 63% of these died before reaching hospital and 37% died in hospital. There were more male deaths, and average age was 54 years. In 23% an autopsy was advised by the medical examiners, more often for pre-hospital deaths. The rate of autopsies was 46% when advice was given for a medico-legal autopsy. CONCLUSION: The rates of both medico-legal and clinically desirable autopsies are very low. Currently, the system in Amsterdam focuses mainly on the former, and the latter with its attendant educational aspects is largely ignored. The role of the government should be expanded to optimise the autopsy system in unnatural deaths following traumatic injuries.     

Accuracy of the AAST organ injury scale for CT evaluation of traumatic liver and spleen injuries

Objective： Detection of abdominal in- jury is a very important component in trauma management, so a precise assessment of liver and spleen injuries includ- ing their severity degree is necessary. There is a good case to believe that in emergency situations the radiologists＇ performance may profit from a systematic approach using established scoring systems. Score systems as the organ injury scale （OIS） drawn up by the American Association for the Surgery of Trauma are a valuable guidance for objec- tive trauma assessment. Aim of this study was to evaluate retrospectively whether a structured approach using the OIS may help improve trauma assessment. Methods： Fifty-three patients, 38 male and 15 female who underwent CT and laparotomy after abdominal trauma were included in this study. The laparotomy was performed by experienced surgeons with a minimum experience of 6 years. While the original CT reports were written by differ- ent radiologists with a minimum experience of 3 years, and then a radiologist with experience of 4 years reviewed the same original CT pictures, resulting in the structured report. Both the original and structured CT results on liver and spleen injuries were transferred into OIS grades. Finally, the initial and structured CT results were compared with theintraoperative findings gathered from the surgery report. Results： Regarding the original CT report we found a mean divergence of 0.68±0.8 （r=-0.45） to the OIS finding in the surgery report for liver injuries （0.69±1.17 for spleen injuries; r=-0.69）. In comparison with the structured approach, where we detected a divergence of 0.8±0.68; r=-0.63 （0.47±0.77 for spleen injuries; r=0.91）, there was no significant difference. However we detected a lower rate of over-diag- nosis in structured approaches. Conclusion： Our study shows that a structured ap- proach to triage abdominal trauma using an imaging check- list does not lead to a significantly higher detection rate, but a nonsignificant trend to reduce the rate of over- diagnoses, thus being more precise in grading the severity grade. Concerning the bias by retrospective study design, further prospective investigations are needed to evaluate the impact of trauma scores on the workflow in emergency department procedure as structured reporting systems are a valuable guidance in other radiological disciplines.     

Perforating small bowel injuries in children: influence of time to operation on outcome

The purpose of this study was to determine whether delay in the diagnosis of small bowel injury (SBI) affected the outcome of paediatric patients who required surgical interventions in the treatment of small bowel injuries. A retrospective chart review was performed on children with traumatic SBI requiring surgical management between January 2000 and December 2002. Diagnostic interval was defined as the time from presentation to operative treatment and delay was an interval of greater than 8 h. Thirteen patients were admitted for operative treatment of SBI. Nine cases were the result of motor vehicle trauma. The mean diagnostic interval for all patients was 9.1 h+/-7.4 h (range 0.6 h-22.5 h). Six patients had a diagnostic delay with a mean diagnostic interval of 15.5 h+/-5.5 h. There was no statistically significant difference found between the prompt and delayed diagnosis groups in terms of complications or length of hospital stay. Our finding of no difference between the prompt and delayed diagnosis groups and a diagnostic delay no longer than 22.5 h may suggest that our local methods of diagnosis and treatment assist in the prevention of unnecessary complications and death.     

Performance of four clinical screening tools to select peri- and early postmenopausal women for dual X-ray absorptiometry

Several methods to select postmenopausal women for dual X-ray absorptiometry (DXA) have been proposed. We decided to compare the performance of three clinical decision rules (SCORE, ORAI, OST) with the usual case-finding strategy based on the presence of a major risk factor for future fracture (CFMRF). The study subjects were 2009 healthy, white, peri- or early postmenopausal women participating in the Danish Osteoporosis Prevention Study (DOPS). DXA results expressed as T-scores and scores on SCORE, ORAI, OST and CFMRF were extracted from the DOPS database. First, we evaluated the screening tools as originally described by the developers. The resulting sensitivities and specificities ranged from 18% to 92% and from 66% to 85%, respectively. Only OST achieved a high sensitivity (92%) with respect to femoral neck T-score –2.5; however, the sensitivity with respect to lumbar spine T-score –2.5 was only 51%. Next, the performance of the screening tools was evaluated against T-score –2.0 (and T-score –2.5) in at least one of the regions: femoral neck, total hip or lumbar spine. Using ROC curve analysis, we determined cut-offs yielding sensitivities as close as possible to 90%. The CFMRF and the ORAI tool were too coarse to yield 90% sensitivity. The performances of OST and SCORE were equal from a clinical perspective in that the sensitivities and the specificities varied from 89% to 94% and from 23% to 28%, respectively. The performance of CFMRF was no better than could be expected by chance, yielding a sensitivity of 19% and a specificity of 85%. Applying SCORE or OST 75% of the women would have to be referred for densitometry to identify 90% of the women with T-score –2.0 (or T-score –2.5) in at least one region. In conclusion, our results question the utility of all the evaluated tools for screening peri- and early postmenopausal women for low BMD. However, if a decision on referral has to be made, it may be based on the simple OST rule, which performed as well as or better than any of the other tools.     

Accuracy of clinician-performed point-of-care ultrasound for the diagnosis of fractures in children and young adults

Introduction

Injury is a major cause of death and disability in children and young adults worldwide. X-rays are routinely performed to evaluate injuries with suspected fractures. However, the World Health Organisation estimates that up to 75% of the world population has no access to any diagnostic imaging services. Use of clinician-performed point-of-care ultrasound to diagnose fractures is not only feasible in traditional healthcare settings, but also in underserved or remote settings. Our objective was to determine the accuracy of clinician-performed point-of-care ultrasound for the diagnosis of fractures in children and young adults presenting to an acute care setting.

Methods

We conducted a prospective cohort study of patients aged <25 years that presented to emergency departments with injuries requiring X-rays or CT for suspected fracture. Paediatric emergency physicians with a 1 h training session diagnosed fractures by point-of-care ultrasound. X-rays or CT were used as the reference standard to determine test performance characteristics.

Results

Point-of-care ultrasound was performed on 212 children and young adults with 348 suspected fractures. Forty-two percent of all bones imaged were non-long bones. The prevalence rate of fracture was 24%. Overall: sensitivity—73% (95% CI: 62-82%), specificity—92% (95% CI: 88-95%); long bones: sensitivity—73% (58-84%), specificity—92% (86-95%); non-long bones: sensitivity—77% (58-90%); specificity—93% (87-97%); age ≥ 18 years: sensitivity—60% (39-78%), specificity—92% (87-96%); age < 18: sensitivity—78 (65-87%), specificity—93% (87-95)%. Majority of errors in diagnosis (>85%) occurred at the ends-of-bones.

Conclusions

Clinicians with focused ultrasound training were able to diagnose fractures using point-of-care ultrasound with a high specificity rate. Specificity rates to rule-in fracture were similar for non-long bone and long bone fractures, as well as in skeletally mature young adults and children with open growth plates. Clinician-performed point-of-care ultrasound accuracy was highest at the diaphyses of long bones, while most diagnostic errors were committed at the ends-of-bones or near joints. Point-of-care ultrasound may serve as a rapid alternative means to diagnose midshaft fractures in settings with limited or no access to X-ray.

A systematic review of prognostic factors for return to work following work-related traumatic hand injury

Study designSystematic review.IntroductionTraumatic hand injuries are frequent cause of work related injuries and can result in prolonged durations of time loss from work.PurposeTo systematically review available evidence to determine which prognostic factors predict return-to-work (RTW) following work-related traumatic hand injuries.MethodsWe searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL and PsycINFO from 1980 to September 2013 and reference lists of articles. Studies investigating any prognostic factors of RTW after traumatic hand injury were included. Two reviewers performed study selection, assessment of methodological quality and data extraction independently of each other. Identified factors were grouped into conceptual prognostic factor categories.ResultsWe assessed 8 studies, which addressed 11 potential prognostic factors (i.e., sociodemographic factors, occupation, work compensation status, treatment related factors, impairment severity, location of injury, etc.). The quality of the studies was low to moderate. Across all included studies, RTW (original or modified work) occurred in over 60% of individuals by 6 months. There was consistent low-moderate quality evidence that individuals with more severe impairments and lower pre-injury income were less likely to RTW, and low-moderate quality evidence that age, gender and level of education had no impact on RTW. Evidence on other commonly cited prognostic factors were limited in the literature.ConclusionImpairment severity and lower pre-injury income showed a consistent association with RTW following occupational hand injury, while other factors demonstrated no or variable effects across studies. Additional high-quality studies are warranted toward improving our understanding of the complex factors that mediate RTW following a traumatic work-related hand injury.Level of evidence2a.     

Use of interventional radiology as initial hemorrhage control to improve outcomes for potentially lethal multiple blunt injuries

IntroductionRecently, trauma management has been markedly improved with interventional radiology (IVR) and damage-control strategies. However, the indications for its use in hemodynamically unstable patients with severe trauma remains unclear. In some cases, IVR may be more effective than surgery for damage-control hemostasis; however, performing IVR in life-threatening trauma settings is challenging. To address this, we practiced and evaluated a trauma-management system with emergency physicians who trained for both severe trauma management, and techniques of surgery and IVR.Materials and methodsAmong the 1822 patients with severe trauma admitted between October 2014 and December 2016, 201 underwent emergency surgery or IVR. Among these, 16 patients whose systolic blood pressure was ≤90 mmHg, without improvement following primary resuscitation, and whose first intervention was IVR, were analyzed. We retrospectively evaluated the admission characteristics, IVR-related characteristics, and prognoses, and compared several parameters before and after IVR.ResultsThis study included 10 men and 6 women (median age: 46 years). IVR was performed for 10 pelvic fractures; five liver-, one splenic-, and one renal injury; and one transection each of the external carotid-, vertebral-, axillosubclavian-, intercostal-, and lumbar arteries. The mean times from the patient arrival, and diagnosis to the start of IVR were 56.3 ± 26.6 and 15.1 ± 3.8 min, respectively. The mean time spent in the angiography suite was 50 min. The systolic blood pressure, pulse rate, base excess/deficit, serum-lactate levels, and D-dimer values were significantly improved after IVR. Although two patients needed additional treatment for morbidities following IVR intervention, all achieved complete recovery. The mortality rate was 25.0%, and no preventable deaths were noted. Eight patients showed unexpected survival.ConclusionsIn some cases, IVR may be the best first measure for resuscitative hemostasis in potentially lethal multiple injuries, given efficient diagnoses/actions and the ability to deal with complications.
