Analysis of preventable trauma deaths and inappropriate trauma care in a rural state

The effects of prehospital plasma on patients with injury: a prehospital plasma resuscitation

BACKGROUND

The prehospital resuscitation of the exsanguinating patient with trauma is time and resource dependent. Rural trauma care magnifies these factors because transportation time to definitive care is increased. To address the early resuscitation needs and trauma-induced coagulopathy in the exsanguinating patient with trauma an aeromedical prehospital thawed plasma-first transfusion protocol was used.

METHODS

Retrospective review of trauma and flight registries between February 1, 2009, and May 31, 2011, was performed. The study population included all patients with traumatic injury transported by rotary wing aircraft who met criteria for massive transfusion protocol

RESULTS

A total of 59 patients identified over 28 months met criteria for initiation of aeromedical initiation of prehospital blood product resuscitation. Nine patients received thawed plasma-first protocol compared with 50 controls. The prehospital plasma group was more commonly on warfarin (22 vs. 2%, p = 0.036) and had a greater degree of coagulopathy measured by international normalized ratio at baseline (2.6 vs. 1.5, p = 0.004) and trauma center arrival (1.6 vs. 1.3, p < 0.001). The prehospital plasma group had a predicted mortality nearly three times greater than controls based on Trauma and Injury Severity Score (0.24 vs. 0.66, p = 0.005). The use of prehospital plasma resuscitation led to a plasma-red blood cell ratio that more closely approximated a 1:1 resuscitation en route (1.3:1.0 vs. not applicable, p < 0.001), at 30 minutes (1.3:1.0 vs. 0.14:1.0, p < 0.001), at 6 hours (0.95:1.0 vs. 0.42:1.0, p < 0.001), and at 24 hours (1.0:1.0 vs. 0.45:1.0, p < 0.001). An equivalent amount of packed red blood cells were transfused between the groups. Despite more significant hypotension, less crystalloid was used in the prehospital thawed plasma group, through 24 hours after injury (6.3 vs. 16.4 L, p = 0.001).

CONCLUSION

Use of plasma-first resuscitation in the helicopter system creates a field ready, mobile blood bank, allowing early resuscitation of the patient demonstrating need for massive transfusion. There was early treatment of trauma-induced coagulopathy. Although there was not a survival benefit demonstrated, there was resultant damage control resuscitation extending to 24 hours in the plasma-first cohort.

Does direct transport to provincial burn centres improve outcomes? A spatial epidemiology of severe burn injury in British Columbia, 2001-2006

BACKGROUND

In Canada and the United States, research has shown that injured patients initially treated at smaller emergency departments before transfer to larger regional facilities are more likely to require longer stays in hospital or suffer greater mortality. It remains unknown whether transport status is an independent predictor of adverse health events among persons requiring care from provincial burn centres.

METHODS

We obtained case records from the British Columbia Trauma Registry for adult patients (age ≥ 18 yr) referred or transported directly to the Vancouver General Hospital and Royal Jubilee Hospital burn centres between Jan. 1, 2001, and Mar. 31, 2006. Prehospital and in-transit deaths and deaths in other facilities were identified using the provincial Coroner Service database. Place of injury was identified through data linkage with census records. We performed bivariate analysis for continuous and discrete variables. Relative risk (RR) of prehospital and in-hospital mortality and hospital stay by transport status were analyzed using a Poisson regression model.

RESULTS

After controlling for patient and injury characteristics, indirect referral did not influence RR of in-facility death (RR 1.32, 95% confidence interval [CI] 0.54- 3.22) or hospital stay (RR 0.96, 95% CI 0.65-1.42). Rural populations experienced an increased risk of total mortality (RR 1.22, 95% CI 1.00-1.48).

CONCLUSION

Transfer status is not a significant indicator of RR of death or hospital stay among patients who received care at primary care facilities before transport to regional burn centres. However, significant differences in prehospital mortality show that improvements in rural mortality can still be made.

Comparison of mortality associated with sepsis in the burn, trauma, and general intensive care unit patient: a systematic review of the literature

The purpose of this systematic review of the literature was to determine the association of sepsis with mortality in the severely injured adult patient by means of a comparative analysis of sepsis in burn and trauma injury with other critically ill populations. The MEDLINE (PubMed), Cochrane Library, and ProQuest databases were searched. The following keywords and MeSH headings were used: "sepsis," septicemia," "septic shock," "epidemiology," "burns," "thermal injury," "trauma," "wounds and injuries," "critical care," "intensive care," "outcomes," and "mortality." Included studies were clinical studies of adult burn, trauma, and critically ill patients that reported survival data for sepsis. Thirty-eight articles were reviewed (9 burn, 11 trauma, 18 general critical care). The age of burn (<45 years) and trauma (34-49 years) groups was lower than the general critical care (57-64 years) population. Sepsis prevalence varied with trauma-injured patients experiencing fewer episodes (2.4%-16.9%) contrasted with burn patients (8%-42.5%) and critical care patients (19%-38%). Survival differed with trauma patients experiencing a lower rate of mortality associated with sepsis (7%-36.9%) compared with the burn (28%-65%) and critical care (21%-53%) groups. This study is the first to compare sepsis outcomes in three distinct patient populations: burn, trauma, and general critical care. Trauma patients tend to have relatively low sepsis-associated mortality; burn patients and the older critical care population have higher prevalence of sepsis with worse outcomes. Great variability of criteria to identify septic patients among studies compromises population comparisons.

Patient safety in pre-hospital emergency tracheal intubation: a comprehensive meta-analysis of the intubation success rates of EMS providers

Introduction

Pre-hospital airway management is a controversial subject, but there is general agreement that a small number of seriously ill or injured patients require urgent emergency tracheal intubation (ETI) and ventilation. Many European emergency medical services (EMS) systems provide physicians to care for these patients while other systems rely on paramedics (or, rarely, nurses). The ETI success rate is an important measure of provider and EMS system success and a marker of patient safety.

Methods

We conducted a systematic search of Medline and EMBASE to identify all of the published original English-language articles reporting pre-hospital ETI in adult patients. We selected all of the studies that reported ETI success rates and extracted information on the number of attempted and successful ETIs, type of provider, level of ETI training and the availability of drugs on scene. We calculated the overall success rate using meta-analysis and assessed the relationships between the ETI success rate and type of provider and between the ETI success rate and the types of drugs available on the scene.

Results

From 1,070 studies initially retrieved, we identified 58 original studies meeting the selection criteria. Sixty-four per cent of the non-physician-manned services and 54% of the physician-manned services reported ETI success rates but the success rate reporting was incomplete in three studies from non-physician-manned services. Median success rate was 0.905 (0.491, 1.000). In a weighted linear regression analysis, physicians as providers were significantly associated with increased success rates, 0.092 (P = 0.0345). In the non-physician group, the use of drug-assisted intubation significantly increased the success rates. All physicians had access to traditional rapid sequence induction (RSI) and, comparing these to non-physicians using muscle paralytics or a traditional RSI, there still was a significant difference in success rate in favour of physicians, 0.991 and 0.955, respectively (P = 0.047).

Conclusions

This comprehensive meta-analysis suggests that physicians have significantly fewer pre-hospital ETI failures overall than non-physicians. This finding, which remains true when the non-physicians administer muscle paralytics or RSI, raises significant patient safety issues. In the absence of pre-hospital physicians, conducting basic or advanced airway techniques other than ETI should be strongly considered.

Rural high north: a high rate of fatal injury and prehospital death

Background

Finnmark County is the northernmost county in Norway. For several decades, the rate of mortality after injury in this sparsely inhabited region has remained above the national average. Following documentation of this discrepancy for the period 1991–1995, improvements to the trauma system were implemented. The present study aims to assess whether trauma-related mortality rates have subsequently improved.

Methods

All injury-associated fatalities in Finnmark from 1995–2004 were identified retrospectively from the National Registry of Death and reviewed. Low-energy trauma in elderly individuals and poisonings were excluded.

Results

A total of 453 cases of trauma-related death occurred during the study period, and 327 of those met the inclusion criteria. Information was retrievable for 266 cases. The majority of deaths (86%) occurred in the prehospital phase. The main causes of death were suicide (33%) and road traffic accidents (21%). Drowning and snowmobile injuries accounted for an unexpectedly high proportion (12 and 8%, respectively). The time of death did not show trimodal distribution. Compared to the previous study period, there was a significant overall decline in injury-related mortality, yet there was no change in place of death, mechanism of injury, or time from injury until death.

Conclusions

Changes in injury-related mortality cannot be linked to improvements in the trauma system. There was no change in the epidemiological patterns of injury. The high rate of on-scene mortality indicates that any major improvement in the number of injury-related deaths lies in targeted prevention.

Norwegian trauma team leaders--training and experience: a national point prevalence study

BACKGROUND

The treatment of trauma victims is a complex multi-professional task in a stressful environment. We previously found that trauma team members perceive leadership as the most important human factor. The aim of the present study was to assess the experience and education of Norwegian trauma team leaders, and allow them to describe their perceived educational needs.

METHODS

We conducted an anonymous descriptive study using a point prevalence methodology based on written questionnaires. All 45 hospitals in Norway receiving severely injured trauma victims were contacted on a randomly selected weeknight during November 2009. Team leaders were asked to specify what trauma related training programs they had participated in, how much experience they had, and what further training they wished, if any.

RESULTS

Response rate was 82%. Slightly more than half of the team leaders were residents. The median working experience as a surgeon among team leaders was 7.5 years. Sixty-eight percent had participated in multi-professional training in non-technical skills, while 54% had passed the advanced trauma life support(ATLS) course. Fifty-one percent were trained in damage control surgery. A median of one course per team leader was needed to comply with the new proposed national standards. Team leaders considered training in damage control surgery the most needed educational objective.

CONCLUSIONS

Level of experience among team leaders was highly variable and their educational background insufficient according to international and proposed national standards. Proposed national standards should be urgently implemented to ensure equal access to high quality trauma care.

Evidence for quality indicators to evaluate adult trauma care: a systematic review

OBJECTIVE

Multiple quality indicators are available to evaluate adult trauma care, but their characteristics and outcomes have not been systematically compared. We sought to systematically review the evidence about the reliability, validity, and implementation of quality indicators for evaluating trauma care.

DATA SOURCES

Search of MEDLINE, EMBASE, CINAHL, and The Cochrane Library up to January 14, 2009; the Gray Literature; select journals by hand; reference lists; and articles recommended by experts in the field.

STUDY SELECTION

Studies were selected that evaluated the reliability, validity, or the impact of one or more quality indicators on the quality of care delivered to patients ≥ 18 yrs of age with a major traumatic injury.

DATA EXTRACTION

Reviewers with methodologic and content expertise conducted data extraction independently.

DATA SYNTHESIS

The literature search identified 6869 citations. Review of abstracts led to the retrieval of 538 full-text articles for assessment; 40 articles were selected for review. Of these, 20 (50%) articles were cohort studies and 13 (33%) articles were case series. Five articles used control groups, including three before and after case series, a case-control study, and a nonrandomized controlled trial. A total of 115 quality indicators in adult trauma care was identified, predominantly measures of hospital processes (62%) and outcomes (17%) of care. We did not identify any posthospital or secondary injury prevention quality indicators. Reliability was described for two quality indicators, content validity for 22 quality indicators, construct validity for eight quality indicators, and criterion validity for 46 quality indicators. A total of 58 quality indicators was implemented and evaluated in three studies. Eight quality indicators had supporting evidence for more than one measurement domain. A single quality indicator, peer review for preventable death, had both reliability and validity evidence.

CONCLUSIONS

Although many quality indicators are available to measure the quality of trauma care, reliability evidence, validity evidence, and description of outcomes after implementation are limited.

Analysis of preventable trauma deaths and opportunities for trauma care improvement in utah

BACKGROUND

The objective is to determine the rate of preventable mortality and the volume and nature of opportunities for improvement (OFI) in care for cases of traumatic death occurring in the state of Utah.

METHODS

A retrospective case review of deaths attributed to mechanical trauma throughout the state occurring between January 1, 2005, and December 31, 2005, was conducted. Cases were reviewed by a multidisciplinary panel of physicians and nonphysicians representing the prehospital and hospital phases of care. Deaths were judged frankly preventable, possibly preventable, or nonpreventable. The care rendered in both preventable and nonpreventable cases was evaluated for OFI according to nationally accepted guidelines.

RESULTS

The overall preventable death rate (frankly and possibly preventable) was 7%. Among those patients surviving to be treated at a hospital, the preventable death rate was 11%. OFIs in care were identified in 76% of all cases; this cumulative proportion includes 51% of prehospital contacts, 67% of those treated in the emergency department (ED), and 40% of those treated post-ED (operating room, intensive care unit, and floor). Issues with care were predominantly related to management of the airway, fluid resuscitation, and chest injury diagnosis and management.

CONCLUSIONS

The preventable death rate from trauma demonstrated in Utah is similar to that found in other settings where the trauma system is under development but has not reached full maturity. OFIs predominantly exist in the ED and relate to airway management, fluid resuscitation, and chest injury management. Resource organization and education of ED primary care providers in basic principles of stabilization and initial treatment may be the most cost-effective method of reducing preventable deaths in this mixed urban and rural setting. Similar opportunities exist in the prehospital and post-ED phases of care.

Explaining regional disparities in traffic mortality by decomposing conditional probabilities

BACKGROUND

In the USA, the mortality rate from traffic injury is higher in rural and in southern regions, for reasons that are not well understood.

METHODS

For 1754 (56%) of the 3142 US counties, we obtained data allowing for separation of the deaths/population rate into deaths/injury, injuries/crash, crashes/exposure and exposure/population, with exposure measured as vehicle miles travelled. A 'decomposition method' proposed by Li and Baker was extended to study how the contributions of these components were affected by three measures of rural location, as well as southern location.

RESULTS

The method of Li and Baker extended without difficulty to include non-binary effects and multiple exposures. Deaths/injury was by far the most important determinant in the county-to-county variation in deaths/population, and accounted for the greatest portion of the rural/urban disparity. After controlling for the rural effect, injuries/crash accounted for most of the southern/northern disparity.

CONCLUSIONS

The increased mortality rate from traffic injury in rural areas can be attributed to the increased probability of death given that a person has been injured, possibly due to challenges faced by emergency medical response systems. In southern areas, there is an increased probability of injury given that a person has crashed, possibly due to differences in vehicle, road, or driving conditions.

Damage control in trauma and abdominal sepsis

Damage control surgery, initially formalized <20 yrs ago, was developed to overcome the poor outcomes in exsanguinating abdominal trauma with traditional surgical approaches. The core concepts for damage control of hemorrhage and contamination control with abbreviated laparotomy followed by resuscitation before definitive repair, although simple in nature, have led to an alteration in which emergent surgery is handled among a multitude of problems, including abdominal sepsis and battlefield surgery. With the aggressive resuscitation associated with damage control surgery, understanding of abdominal compartment syndrome has expanded. It is probably through avoiding this clinical entity that the greatest improvement in surgical outcomes for various emergent surgical problems has occurred in the past two decades. However, with its success, new problems have emerged, including increases in enterocutaneous fistulas and open abdomens. But as with any crisis, innovative strategies are being developed. New approaches to control of the open abdomen and reconstruction of the abdominal wall are being developed from negative pressure dressing therapies to acellular allograft meshes. With further understanding of new resuscitative strategies, the need for damage control surgery may decline, along with its concomitant complications, at the same time retaining the success that damage control surgery has brought to the critically ill trauma and general surgery patient in the past few years.

A population-based analysis of injury-related deaths and access to trauma care in rural-remote Northwest British Columbia

BACKGROUND

Injury rates and injury mortality rates are generally higher in rural and remote communities compared with urban jurisdictions as has been shown to be the case in the rural-remote area of Northwest (NW) British Columbia (BC). The purpose of study was to identify: (1) the place and timing of death following injury in NW BC, (2) access to and quality of local trauma services, and (3) opportunities to improve trauma outcomes.

METHODS

Quantitative data from demographic and geographic databases, the BC Trauma Registry, Hospital discharge abstract database, and the BC Coroner's Office, along with qualitative data from chart reviews of selected major trauma cases, and interviews with front-line trauma care providers were collated and analyzed for patients sustaining injury in NW BC from April 2001 to March 2006.

RESULTS

The majority of trauma deaths (82%) in NW BC occur prehospital. Patients arriving alive to NW hospitals have low hospital mortality (1.0%), and patients transferring from NW BC to tertiary centers have better outcomes than matched patients achieving direct entry into the tertiary center by way of geographic proximity. Access to local trauma services was compromised by: incident discovery, limited phone service (land lines/cell), incomplete 911 emergency medical services system access, geographical and climate challenges compounded by limited transportation options, airport capabilities and paramedic training level, dysfunctional hospital no-refusal policies, lack of a hospital destination policies, and lack of system leadership and coordination.

CONCLUSION

Improving trauma outcomes in this rural-remote jurisdiction requires a systems approach to address root causes of delays in access to care, focusing on improved access to emergency medical services, hospital bypass and destination protocols, improved transportation options, advanced life support transfer capability, and designated, coordinated local trauma services.

Optimal use of blood in trauma patients

Injury is rapidly becoming the leading cause of death worldwide, and uncontrolled hemorrhage is the leading cause of potentially preventable death. In addition to crystalloid and/or colloid based resuscitation, severely injured trauma patients are routinely transfused RBCs, plasma, platelets, and in some centers either cryoprecipitate or fibrinogen concentrates or whole blood. Optimal timing and quantity of these products in the treatment of hypothermic, coagulopathic and acidotic trauma patients is unclear. The immediate availability of these components is important, as most hemorrhagic deaths occur within the first 3-6h of patient arrival. While there are strongly held opinions and longstanding traditions in their use, there are little data within which to logically guide resuscitation therapy. Many current recommendations are based on euvolemic elective surgery patients and incorporate laboratory data parameters not widely available in the first few minutes after patient arrival. Finally, blood components themselves have evolved over the last 30 years, with great attention paid to product safety and inventory management, yet there are surprisingly limited clinical outcome data describing the long term effects of these changes, or how the components have improved clinical outcomes compared to whole blood therapy. When focused on survival of the rapidly bleeding trauma patient, it is unclear if current component therapy is equivalent to whole blood transfusion. In fact data from the current war in Iraq and Afghanistan suggest otherwise. All of these factors have contributed to the current situation, whereby blood component therapy is highly variable and not driven by long term patient outcomes. This review will address the issues raised above and describe recent trauma patient outcome data utilizing predetermined plasma:platelet:RBC transfusion ratios and an ongoing prospective observational trauma transfusion study.

Mannequin or standardized patient: participants' assessment of two training modalities in trauma team simulation

Background

Trauma team training using simulation has become an educational compensation for a low number of severe trauma patients in 49 of Norway's 50 trauma hospitals for the last 12 years. The hospitals' own simple mannequins have been employed, to enable training without being dependent on expensive and advanced simulators. We wanted to assess the participants' assessment of using a standardized patient instead of a mannequin.

Methods

Trauma teams in five hospitals were randomly exposed to a mannequin or a standardized patient in two consecutive simulations for each team. In each hospital two teams were trained, with opposite order of simulation modality. Anonymous, written questionnaires were answered by the participants immediately after each simulation. The teams were interviewed as a focus group after the last simulation, reflecting on the difference between the two simulation modalities. Outcome measures were the participants' assessment of their own perceived educational outcome and comparison of the models, in addition to analysis of the interviews.

Results

Participants' assessed their educational outcome to be high, and unrelated to the order of appearance of patient model. There were no differences in assessment of realism and feeling of embarrassment. Focus groups revealed that the participants felt that the choice between educational modalities should be determined by the simulated case, with high interaction between team and patient being enhanced by a standardized patient.

Conclusion

Participants' assessment of the outcome of team training seems independent of the simulation modality when the educational goal is training communication, co-operation and leadership within the team.

Resuscitation and transfusion principles for traumatic hemorrhagic shock

The transfusion approach to massive hemorrhage has continually evolved since it began in the early 1900s. It started with fresh whole blood and currently consists of virtually exclusive use of component and crystalloid therapy. Recent US military experience has reinvigorated the debate on what the most optimal transfusion strategy is for patients with traumatic hemorrhagic shock. In this review we discuss recently described mechanisms that contribute to traumatic coagulopathy, which include increased anti-coagulation factors and hyperfibrinolysis. We also describe the concept of damage control resuscitation (DCR), an early and aggressive prevention and treatment of hemorrhagic shock for patients with severe life-threatening traumatic injuries. The central tenants of DCR include hypotensive resuscitation, rapid surgical control, prevention and treatment of acidosis, hypothermia, and hypocalcemia, avoidance of hemodilution, and hemostatic resuscitation with transfusion of red blood cells, plasma, and platelets in a 1:1:1 unit ratio and the appropriate use of coagulation factors such as rFVIIa and fibrinogen-containing products (fibrinogen concentrates, cryoprecipitate). Fresh whole blood is also part of DCR in locations where it is available. Additional concepts to DCR since its original description that can be considered are the preferential use of "fresh" RBCs, and when available thromboelastography to direct blood product and hemostatic adjunct (anti-fibrinolytics and coagulation factor) administration. Lastly we discuss the importance of an established massive transfusion protocol to rapidly employ DCR and hemostatic resuscitation principles. While the majority of recent trauma transfusion papers are supportive of these general concepts, there is no Level 1 or 2 data available. Taken together, the preponderance of data suggests that these concepts may significantly decrease mortality in massively transfused trauma patients.

Leadership is the essential non-technical skill in the trauma team--results of a qualitative study

Background

Trauma is the leading cause of death for young people in Norway. Studies indicate that several of these deaths are avoidable if the patient receives correct initial treatment. The trauma team is responsible for initial hospital treatment of traumatized patients, and team members have previously reported that non-technical skills as communication, leadership and cooperation are the major challenges. Better team function could improve patient outcome. The aim of this study was to obtain a deeper understanding of which non-technical skills are important to members of the trauma team during initial examination and treatment of trauma patients.

Methods

Twelve semi-structured interviews were conducted at four different hospitals of various sizes and with different trauma load. At each hospital a nurse, an anaesthesiologist and a team leader (surgeon) were interviewed. The conversations were transcribed and analyzed using systematic text condensation according to the principles of Giorgi's phenomenological analysis as modified by Malterud.

Results and conclusion

Leadership was perceived as an essential component in trauma management. The ideal leader should be an experienced surgeon, have extensive knowledge of trauma care, communicate clearly and radiate confidence. Team leaders were reported to have little trauma experience, and the team leaders interviewed requested more guidance and supervision. The need for better training of trauma teams and especially team leaders requires further investigation and action.

Patterns of mortality and causes of death in polytrauma patients--has anything changed?

INTRODUCTION

Numerous articles have examined the pattern of traumatic deaths. Most of these studies have aimed to improve trauma care and raise awareness of avoidable complications. The aim of the present review is to evaluate whether the distribution of complications and mortality has changed.

MATERIALS AND METHODS

A review of the published literature to identify studies examining patterns and causes of death following trauma treated in level 1 hospitals published between 1980 and 2008. PubMed was searched using the following terms: Trauma Epidemiology, Injury Pattern, Trauma Deaths, and Causes of Death. Three time periods were differentiated: (n=6, 1980-1989), (n=6, 1990-1999), and (n=10, 2000-2008). The results were limited to the English and/or German language. Manuscripts were analysed to identify the age, injury severity score (ISS), patterns and causes of death mentioned in studies.

RESULTS

Twenty-two publications fulfilled the inclusion criteria for the review. A decrease of haemorrhage-induced deaths (25-15%) has occurred within the last decade. No considerable changes in the incidence and pattern of death were found. The predominant cause of death after trauma continues to be central nervous system (CNS) injury (21.6-71.5%), followed by exsanguination (12.5-26.6%), while sepsis (3.1-17%) and multi-organ failure (MOF) (1.6-9%) continue to be predominant causes of late death.

DISCUSSION

Comparing manuscripts from the last three decades revealed a reduction in the mortality rate from exsanguination. Rates of the other causes of death appear to be unchanged. These improvements might be explained by developments in the availability of multislice CT, implementation of ATLS concepts and logistics of emergency rescue.

Surgical trauma referrals from rural level III hospitals: should our community colleagues be doing more, or less?

BACKGROUND

Rural citizens die more frequently because of trauma than their urban counterparts. Skill maintenance is a potential issue among rural surgeons because of infrequent exposure to severely injured patients. The primary goal was to evaluate the outcomes of multiple injuries patients who required a laparotomy after referral from level III trauma centers.

METHODS

All severely injured patients (injury severity score >12) referred to a level I trauma center from level III hospitals, during a 48-month period were evaluated. Comparisons between referrals (level III and IV) as well as survivors and nonsurvivors used standard statistical methodology.

RESULTS

One thousand two hundred and thirty patients (35%) were transferred from level III (33%) and level IV (67%) centers (43% underwent an operative procedure). Only 13% required a laparotomy, whereas 87% needed procedures from other subspecialists. Referred patients had a mean injury severity score of 28, length of stay of 28 days, and mortality rate of 26%. More patients arrived hemodynamically unstable from level IV (55%) versus level III (35%) hospitals (p < 0.05). Nonsurvivors from level III centers were more likely to transfer via aircraft (100%) than from level IV hospitals (55%) (p < 0.05). Most (91%) definitive general surgery procedures could have been completed by surgeons at level III centers; however, 90% also had multisystem injuries requiring treatment by other subspecialists.

CONCLUSIONS

Most severely injured patient referrals from level III and IV trauma centers in Western Canada are appropriate. The lack of consistent subspecialty coverage mandates most transfers from level III hospitals. This data will be used to engage rural Alberta physicians in an educational outreach program.

An analysis of in-hospital deaths at a modern combat support hospital

BACKGROUND

Analysis of the epidemiology and attribution of in-hospital deaths is a critical component of learning and process improvement for any trauma center. We sought to perform a detailed analysis of in-hospital deaths at a combat support hospital.

METHODS

All patients with trauma who survived to admission and subsequently died before transfer or discharge during a 1-year period were included. The timing, location, pathogenesis, and circumstances surrounding the death were recorded. Opportunities for improvement (OI) of care were identified for analysis. Cases were presented to a panel of experts, and preventability of the deaths was scored on a continuous 10-point scale.

RESULTS

There were 151 deaths, with the predominant mechanisms of gunshot wounds (GSW) (47%) and blast injuries (42%). Most had severe injuries, with a mean Injury Severity Score of 38, pH of 7.09, and base deficit of 12. Predominant causes of death were head injury (45%) and hemorrhage (32%), and 78% died within 1 hour of admission. Most deaths occurred during the intensive care (35%) or resuscitation phases (31%), but the majority of deaths among nonexpectant patients occurred during the operative phase (38%). OI were identified in 74 deaths (49%), and were found in 78% of nonexpectant deaths. Most improvement opportunities occurred during the resuscitation and transport phases. Most potential improvements were identified at the system level (54%) or individual provider level (42%). Preventability scoring showed excellent inter-rater reliability (r = 0.92, p < 0.001). Deaths with high preventability scores (mean >54) were primarily related to delays in hemorrhage control during the transportation (47%) or resuscitation (43%) phases, and attributed to the system (63%) and individual provider levels (70%).

CONCLUSIONS

In-hospital combat trauma-related deaths at a modern Combat support hospital differ significantly from their civilian counterparts, and present multiple OI of care and potential salvage. Delays in prehospital and in-hospital hemorrhage control are the primary contributors to potential preventability.

Warm fresh whole blood is independently associated with improved survival for patients with combat-related traumatic injuries

BACKGROUND

Increased understanding of the pathophysiology of the acute coagulopathy of trauma has lead many to question the current transfusion approach to hemorrhagic shock. We hypothesized that warm fresh whole blood (WFWB) transfusion would be associated with improved survival in patients with trauma compared with those transfused only stored component therapy (CT).

METHODS

We retrospectively studied US Military combat casualty patients transfused >or=1 unit of red blood cells (RBCs). The following two groups of patients were compared: (1) WFWB, who were transfused WFWB, RBCs, and plasma but not apheresis platelets and (2) CT, who were transfused RBC, plasma, and apheresis platelets but not WFWB. The primary outcomes were 24-hour and 30-day survival.

RESULTS

Of 354 patients analyzed there were 100 in the WFWB and 254 in the CT group. Patients in both groups had similar severity of injury determined by admission eye, verbal, and motor Glasgow Coma Score, base deficit, international normalized ratio, hemoglobin, systolic blood pressure, and injury severity score. Both 24-hour and 30-day survival were higher in the WFWB cohort compared with CT patients, 96 of 100 (96%) versus 223 of 254 (88%), (p = 0.018) and 95% to 82%, (p = 0.002), respectively. An increased amount (825 mL) of additives and anticoagulants were administered to the CT compared with the WFWB group, (p < 0.001). Upon multivariate logistic regression the use of WFWB and the volume of WFWB transfused was independently associated with improved 30-day survival.

CONCLUSIONS

In patients with trauma with hemorrhagic shock, resuscitation strategies that include WFWB may improve 30-day survival, and may be a result of less anticoagulants and additives with WFWB use in this population.

Imaging may delay transfer of rural trauma victims: a survey of referring physicians

BACKGROUND

Delayed transfer to a trauma center due to unnecessary imaging results in suboptimal patient outcome and increases healthcare costs. Unnecessary imaging may result from beliefs regarding trauma center requirements and legal concerns. We hypothesized that referring physicians consider factors other than clinical criteria when deciding to order imaging studies before transfer of trauma patients.

METHODS

A mail survey of 218 referring physicians to a level I trauma center elicited factors affecting decision to obtain imaging studies before transfer. Graded answers to six questions were obtained and demographics of the physician respondent. Statistical analysis was performed using Fisher's exact test.

RESULTS

One hundred forty-nine of 218 surveys were returned (68.3%). One-third (33.1%) of respondents obtain imaging because of perceived expectations of the receiving trauma center, independent of patient acuity. Twenty percent incorrectly think that the law prohibits transfer before patients are stabilized. Twenty-eight percent obtain imaging because of liability concerns, even if that imaging delays transfer. Overall, 45% obtain imaging for either perceived requirement or liability concern. Non-advanced trauma life support (ATLS)-certified physicians are more likely to use all available resources before transfer than ATLS-certified physicians.

CONCLUSIONS

Factors other than patient care dictate imaging acquisition in almost half of those surveyed. Misperception of expectations, misunderstanding of legal imperatives, and liability concerns all delay transport of the injured. ATLS-certified individuals use imaging more appropriately, thus, promoting more timely transfer. State-wide protocols, education, and liability reform may reduce transport delays.

Rural trauma: is trauma designation associated with better hospital outcomes?

CONTEXT

While trauma designation has been associated with lower risk of death in large urban settings, relatively little attention has been given to this issue in small rural hospitals.

PURPOSE

To examine factors related to in-hospital mortality and delayed transfer in small rural hospitals with and without trauma designation.

METHODS

Analysis of data from the Nationwide Inpatient Sample for discharges between 1998 and 2003 of patients hospitalized with moderate to major traumatic injury in nonfederal, short-stay rural hospitals with annual discharges of 1,500 or fewer patients (N = 9,590). Logistic regression was used to control for patient and hospital characteristics, stratifying by hospital volume. Main outcome measures were in-hospital death and transfer to another acute care facility after initial admission.

FINDINGS

A total of 333 patients (3.5%) died in-hospital. After adjusting for patient, injury and hospital characteristics, in-hospital death was more likely among patients treated at the non-designated hospitals with fewer than 500 discharges per year (OR 2.35; 95% CI 1.25-4.41) than among patients treated at similar trauma-designated hospitals. Patients admitted to non-designated hospitals were more likely to be transferred after admission, although this finding was significant only in the larger-volume hospitals with discharges of 500-1,500 per year (OR 1.41, 95% CI 1.08-1.83).

CONCLUSIONS

Associations between trauma designation and outcomes in rural hospitals warrant further study to determine whether expanding designation to more rural hospitals might lead to further improvement in trauma outcomes.

Missed injuries in trauma patients: A literature review

BACKGROUND

Overlooked injuries and delayed diagnoses are still common problems in the treatment of polytrauma patients. Therefore, ongoing documentation describing the incidence rates of missed injuries, clinically significant missed injuries, contributing factors and outcome is necessary to improve the quality of trauma care. This review summarizes the available literature on missed injuries, focusing on overlooked muscoloskeletal injuries.

METHODS

Manuscripts dealing with missed injuries after trauma were reviewed. The following search modules were selected in PubMed: Missed injuries, Delayed diagnoses, Trauma, Musculoskeletal injuires. Three time periods were differentiated: (n = 2, 1980-1990), (n = 6, 1990-2000), and (n = 9, 2000-Present).

RESULTS

We found a wide spread distribution of missed injuries and delayed diagnoses incidence rates (1.3% to 39%). Approximately 15 to 22.3% of patients with missed injuries had clinically significant missed injuries. Furthermore, we observed a decrease of missed pelvic and hip injuries within the last decade.

CONCLUSION

The lack of standardized studies using comparable definitions for missed injuries and clinically significant missed injuries call for further investigations, which are necessary to produce more reliable data. Furthermore, improvements in diagnostic techniques (e.g. the use of multi-slice CT) may lead to a decreased incidence of missed pelvic injuries. Finally, the standardized tertiary trauma survey is vitally important in the detection of clinically significant missed injuries and should be included in trauma care.

Team-oriented training for damage control surgery in rural trauma: a new paradigm

BACKGROUND

The geography of Norway has led to an initiative to train teams from rural hospitals in damage control surgery using a team-oriented approach based on Crew Resource Management. Our aim was to evaluate this approach and its impact on trauma care in rural hospitals across Norway.

METHODS

Thirty-eight teams from 21 hospitals participated in 10 courses (during the years 2003-2006) where providers from the same hospital trained as a team. Each course consisted of interactive lecture modules and operative sessions on live porcine models that emphasize communication, collaboration and team-based problem solving. The data collection tools were a postcourse questionnaire and a phone survey of participating hospitals.

RESULTS

Teams consisted of surgeons (34%), operating room nurses (35%), and anesthesiology staff (31%). Almost all course participants (N = 228, 99%) reported a dramatic increase in their proficiency with damage control techniques. There was a mean increase of 2.3 points in proficiency with extraperitoneal pelvic packing and 1.5 points with emergency thoracotomy on a 5-step Likert scale. The team approach was perceived as crucial by 218 (94%) of participants. The phone survey revealed 12 cases of lifesaving rural damage control operations by course participants in the past 3 years (estimated cost: $15,075 per life saved). Of the 18 hospitals surveyed, 17 modified their trauma protocols as a result of the course.

CONCLUSION

Teaching damage control surgery using a team-oriented approach is an innovative educational method for rural hospitals.

Preventable or potentially preventable mortality at a mature trauma center

OBJECTIVE

The objective of this study was to analyze the preventable and potentially preventable deaths occurring at a mature Level I trauma center.

METHODS

All trauma patients that died during their initial hospital admission during an 8-year period (January, 1998 to December, 2005) were analyzed. The deaths were initially reviewed at a weekly Morbidity and Mortality (M&M) conference followed by a multidisciplinary (Trauma Surgery, Critical Care, Emergency Medicine, Neurosurgery, Nursing, and Coroner) Combined Trauma Death Review Committee, and were classified into nonpreventable, potentially preventable, and preventable deaths. All preventable and potentially preventable deaths were identified for the purpose of the study. Quality improvement death forms included data on epidemiology, vital signs, injury severity, type of injury, probability of survival with Trauma and Injury Severity Score methodology, preventability (nonpreventable, potentially preventable, and preventable deaths), errors in the evaluation and management of the patient, and classification of errors (system, judgment, knowledge). Additional injury details, clinical course, circumstances leading to the death and autopsy findings were abstracted from the trauma registry and individual chart review.

RESULTS

During the study period, 35,311 patients meeting trauma registry criteria were admitted and a total of 2,081 (5.9%) deaths occurred. Fifty-one deaths were classified as preventable or potentially preventable deaths (0.1% of admissions, 2.5% of deaths). Eleven of them (0.53% of deaths) were classified as preventable and 40 (1.92% of deaths) as potentially preventable deaths. Mean age was 40 years, 66.7% were men, mean Injury Severity Score was 27, 74.5% were blunt. The most common cause of death was bleeding (20, 39.2%) followed by multiple organ dysfunction syndrome (14, 27.5%) and cardiorespiratory arrest (8, 15.6%). This was caused by a delay in treatment (27, 52.9%), clinical judgment error (11, 21.6%), missed diagnosis (6, 11.8%), technical error (4, 7.8%), and other (3, 5.9%). The deaths peaked at two time periods: 26 (51.1%) during the first 24 hours and 16 (31.4%) after 7 days. Only one patient (2.0%) died in the first hour. The most common location of death was the intensive care unit (28, 54.9%), operating room (13, 25.5%), and emergency room (5, 9.8%).

CONCLUSION

Preventable or potentially preventable deaths are rare but do occur at an academic Level I trauma center. Delay in treatment and error in judgment are the leading causes of preventable and potentially preventable deaths.

Overtriage in trauma - what are the causes?

BACKGROUND

Different criteria are employed to activate trauma teams. Because of a growing concern about overtriage, the objective of this study was to investigate the performance of our trauma team's activation protocol.

METHODS

Injured patients with trauma team activation (TTA), admission to an intensive care unit or surgical intermediate care unit with a trauma diagnosis, or trauma-related death in the emergency department were investigated retrospectively from 1 January 2004 to 31 December 2005. Different TTA criteria were analysed with respect to sensitivity, positive predictive value (PPV) and overtriage (1 - PPV).

RESULTS

Eight hundred and nine patients were included, 185 (23%) of whom had an Injury Severity Score (ISS) of more than 15. The performance of our protocol showed a sensitivity of 87%, PPV of 22% and overtriage of 78%. The mechanism of injury as a TTA criterion had a sensitivity of 14%, PPV of 7% and overtriage of 93%. Physiological/anatomical criteria and interfacility transfer showed higher PPV and less overtriage. Undertriage (no TTA despite ISS > 15) was identified in 23 patients (13%), 18 of whom were hospital transfers.

CONCLUSION

A TTA protocol based on physiological, anatomical and interfacility transfer criteria seems to yield a higher precision than, in particular, that based on mechanism of injury criteria. Because of substantial overtriage in our hospital, the TTA protocol needs to be re-evaluated.

Causes of death in U.S. Special Operations Forces in the global war on terrorism: 2001-2004

BACKGROUND

Effective combat trauma management strategies depend upon an understanding of the epidemiology of death on the battlefield.

METHODS

A panel of military medical experts reviewed photographs and autopsy and treatment records for all Special Operations Forces (SOF) who died between October 2001 and November 2004 (n = 82). Fatal wounds were classified as nonsurvivable or potentially survivable. Training and equipment available at the time of injury were taken into consideration. A structured analysis was conducted to identify equipment, training, or research requirements for improved future outcomes.

RESULTS

Five (6%) of 82 casualties had died in an aircraft crash, and their bodies were lost at sea; autopsies had been performed on all other 77 soldiers. Nineteen deaths, including the deaths at sea were noncombat; all others were combat related. Deaths were caused by explosions (43%), gunshot wounds (28%), aircraft accidents (23%), and blunt trauma (6%). Seventy of 82 deaths (85%) were classified as nonsurvivable; 12 deaths (15%) were classified as potentially survivable. Of those with potentially survivable injuries, 16 causes of death were identified: 8 (50%) truncal hemorrhage, 3 (19%) compressible hemorrhage, 2 (13%) hemorrhage amenable to tourniquet, and 1 (6%) each from tension pneumothorax, airway obstruction, and sepsis. The population with nonsurvivable injuries was more severely injured than the population with potentially survivable injuries. Structured analysis identified improved methods of truncal hemorrhage control as a principal research requirement.

CONCLUSIONS

The majority of deaths on the modern battlefield are nonsurvivable. Improved methods of intravenous or intracavitary, noncompressible hemostasis combined with rapid evacuation to surgery may increase survival.

Clinician-performed focused sonography for the resuscitation of trauma

Traumatic death remains pandemic. The majority of preventable deaths occur early and are due to injuries or physiologic derangements in the airway, thoracoabdominal cavities, or brain. Ultrasound is a noninvasive and portable imaging modality that spans a spectrum between the physical examination and diagnostic imaging. It allows trained examiners to immediately confirm important syndromes and answer clinical questions. Newer technologies greatly increase the fidelity, accessibility, ease of use, and informatic manipulation of the results. The early bedside use of focused ultrasound as the initial imaging modality used to detect hemoperitoneum and hemopericardium in the resuscitation of the injured patient has become an accepted standard of care. Widespread dissemination of basic ultrasound skills and technology to facilitate this brings ultrasound to many resuscitative and critical care areas. Although not as widely appreciated, the focused use of ultrasound may also have a role in detecting hemothoraces and pneumothoraces, guiding airway management, and detecting increased intracranial pressure. Intensivists generally utilize a treating philosophy that requires the real-time integration of many divergent sources of information regarding their patients' anatomy and physiology. They are therefore positioned to take advantage of focused resuscitative ultrasound, which offers immediate diagnostic information in the early care of the critically injured.

Trauma care at rural level III trauma centers in a state trauma system

BACKGROUND

Although much has been written about the benefits of trauma center care, most experiences are urban with large numbers of patients. Little is known about the smaller, rural trauma centers and how they function both independently and as part of a larger trauma system. The state of Missouri has designated three levels of trauma care. The cornerstone of rural trauma care is the state-designated Level III trauma center. These centers are required to have the presence of a trauma team and trauma surgeon but do not require orthopedic or neurosurgical coverage. The purpose of this retrospective study was to determine how Level III trauma centers compared with Level I and Level II centers in the Missouri trauma system and, secondly, how trauma surgeon experience at these centers might shape future educational efforts to optimize rural trauma care.

METHODS

During a 2-year period in 2002 and 2003, the state trauma registry was queried on all trauma admissions for centers in the trauma system. Demographics and patient care outcomes were assessed by level of designation. Trauma admissions to the Level III centers were examined for acuity, severity, and type of injury. The experiences with chest, abdominal, and neurologic trauma were examined in detail.

RESULTS

A total of 24,392 patients from 26 trauma centers were examined, including all eight Level III centers. Acuity and severity of injuries were higher at Level I and II centers. A total of 2,910 patients were seen at the 8 Level III centers. Overall deaths were significantly lower at Level III centers (Level I, 4% versus Level II, 4% versus Level III, 2%, p < 0.001). Numbers of patients dying within 24 hours were no different among levels of trauma care (Level I, 37% versus Level II, 30% versus Level III, 32%). Among Level III centers 45 (1.5%) patients were admitted in shock, and 48 (2%) had a Glasgow Coma Scale score <9. Twenty-six patients had a surgical head injury (7 epidural, 19 subdural hematomas). Twenty-eight patients (1%) needed a chest or abdominal operation. There were 15 spleen and 12 liver injuries with an Abbreviated Injury Score of 4 or 5.

CONCLUSIONS

Level III trauma centers performed as expected in a state trauma system. Acuity and severity were less as was corresponding mortality. There were a paucity of life-threatening head, chest, and abdominal injuries, which provide a challenge to the rural trauma surgeon to maintain necessary skills in management of these critical injuries.

Prehospital care of the injured: what's new

Emergency medical services (EMS) play a critical role in the trauma system as the point of initial patient care and stabilization and in determining the regional flow of patients and the commitment of resources to the critically injured. Trauma surgeons and emergency physicians need to be involved in the organizational planning of EMS systems to ensure that uniform patient care protocols are developed for triage and treatment. Ongoing efforts should focus on addressing national variability in care provided after injury to ensure optimal outcome for patients in all regions. Through additional research, the best practice and optimal EMS system design will continue to be defined.

Rural Motor Vehicle Crash Risk of Death is Higher After Controlling for Injury Severity

BACKGROUND

Motor vehicle crash (MVC) mortality rates are inversely related to population density. The purpose of this study was to analyze if there is a regional variation in the risk of MVC death after controlling for injury severity.

METHODS

The study utilized the Crash Outcome Data Evaluation System (CODES) data set in Nebraska. All fatal or injury-related crashes during a 4-year period (1996 through 1999) were analyzed. Injury Severity Scores (ISSs) were calculated from the CODES listed International Classification of Diseases diagnoses. Logistic regression analysis was performed to analyze the odds ratio for death in three rural county groupings compared with urban locations.

RESULTS

During the 4-year period, 56,727 people were injured and 1,237 were killed in 38,493 MVCs. Of these, 45,222 (78%) records had complete information on variables of interest. In addition, 28,859 (50%) records had enough information to calculate an ISS. A total of 22,181 (39%) records had complete information on the variables of interest and ISSs. After adjusting for the effects of speed limit, age, and alcohol involvement (but not ISS), the odds of death were 1.24 (1.01-1.53) higher in the large, non-adjacent and 1.38 (1.14-1.66) small, non-adjacent rural counties. After adjusting for the effect of ISS, the odds of death were 1.98 (1.18-3.31) higher in the small, non-adjacent rural counties.

CONCLUSION

After controlling for ISS, the risk of MVC death is nearly twice as high in the most rural counties in Nebraska. This finding suggests that variation in medical care may contribute to this regional variation.

Preventable deaths in patients admitted from emergency department

BACKGROUND

There is limited data about how appropriate medical care is in the emergency department (ED).

OBJECTIVES

To investigate the rate and types of preventable deaths among patients with early mortality after emergency admission from the ED.

METHODS

We retrospectively reviewed charts of early mortality (defined as mortality which occurred within 24 hours after admission from the ED) over a 3 year period. Those patients with terminal cancer or out of hospital cardiac arrest (OHCA) at presentation were excluded. Two independent assessors reviewed each eligible chart and determined whether early mortality was preventable. Any disagreements were resolved through discussion between the investigators. A mortality event was considered preventable if actions or missed actions were identified that would have prevented the death. The types of preventability were categorised as misdiagnosis, delayed diagnosis, and inappropriate medical management. Interrater reliability in the initial determination was assessed using Cohen kappa statistic.

RESULTS

Over a 3 year period, 210 early mortality cases were identified. Excluding patients with terminal cancer or OHCA, the rate of preventable deaths was 25.8% (32/124). The types of preventability were inappropriate medical management (17 patients), delayed diagnosis (eight), and misdiagnosis (seven). There was good agreement between assessors with a Cohen kappa statistic of 0.81.

CONCLUSIONS

Preventable deaths in emergency admitted patients with early mortality are not uncommon. Analysis and identification of preventability early mortality by using a chart based method may be used as a quality assurance index in emergency medical care.

Training multiprofessional trauma teams in Norwegian hospitals using simple and low cost local simulations

CONTEXT & OBJECTIVE

Norwegian hospitals' trauma teams are seldom exposed to severely injured patients. We developed and implemented a one-day multi-professional training course for hospital trauma teams in order to improve communication, cooperation and leadership.

METHODS

Training courses were held in 28 Norwegian hospitals with learning objectives: improved team work, common understanding of treatment priorities and principles, communication skills, and threats to efficient communication. Two trauma teams in each hospital had two consecutive simulations in their hospital's own emergency room, as part of the course. Simulation was based on real cases, with a low-fidelity mannequin as patient. Participants completed questionnaires before and after the training course.

RESULTS

A total of 2,860 trauma team members participated in the courses, of which 1,237 took part in the simulation. Independent of hospital size, the participants reported leadership and communication to be major obstacles during their last real trauma team participation. Immediately after the training, all participants reported highly fulfilled educational expectations and a high perception of learning, and taking part in the practical simulation improved the evaluation. Nurses scored their outcome significantly higher than physicians. Participants from minor hospitals reported as great a benefit from the training as personnel from major hospitals.

CONCLUSIONS

Local team training is a feasible approach and team simulation offers an excellent opportunity to practise demanding and infrequent challenges. The simulation format makes it possible to integrate training on interpersonal skills as well as communication and leadership under stress. Continued requests for such training in Norway support this conclusion.

In-house trauma attendings: is there a difference?

INTRODUCTION

Outcomes of patients who met trauma activation criteria were examined before and after implementation of in-house attending call.

MATERIALS AND METHODS

Outcomes for the out-of-house period (OH) (February 1, 2001 to October 31, 2002) were compared with the in-house period (IH) (November 1, 2002 to June 30, 2004). Measures included overall mortality, length of stay (LOS) in the hospital, intensive care unit (ICU) and emergency department, and preventable deaths.

RESULTS

A total of 2,019 trauma activations were studied (1,036 OH, 983 IH). The groups were equivalent on admission. There was no difference in hospital LOS, ICU LOS, ventilator days, or overall mortality. Preventable deaths occurred in 8.1% of the OH group and in 1.0% of the IH group (P < .02).

CONCLUSIONS

Aggregate statistics and the use of surrogate markers to determine outcomes may not accurately portray the impact of attending surgeons on the quality of care. Implementation of in-house call resulted in a decreased incidence of preventable deaths.

Training trauma teams in the Nordic countries: an overview and present status

BACKGROUND

During the last decade there has been an increased interest in the organisation and quality of trauma care in the Nordic countries. Still, most patients are initially cared for at hospitals with low caseloads of severe trauma. More than 200 hospitals offer initial care to trauma patients. Training of trauma teams using simulators or simulated patients has evolved in the same period, as one important factor to overcome lack of practical training. This overview describes the present state of trauma team training in the Nordic countries.

METHODS

Members of a Nordic working group on the use of simulation in medicine reviewed present literature on training with simulation and described the present use of team training in their own countries during winter 2004.

RESULTS

There is an increasing amount of evidence indicating that training of teams with simulation reduces treatment errors and improves performance. The training activities do not need to be complex, but skilled debriefing seems necessary. Few Nordic hospitals train their trauma teams. The training activities vary considerably between and within countries.

CONCLUSION

There is considerable evidence supporting an increased use of experience gained in other high-risk domains where training in communication, leadership and decision-making is the focus for safety and improvement efforts. There is a need for more widespread training of trauma teams. The different training activities actually undertaken should be scientifically evaluated.

Analysis of prior health system contacts as a harbinger of subsequent fatal injury in American Indians

CONTEXT

Many American Indian nations, tribes, and bands are at an elevated risk for premature death from unintentional injury. Previous research has documented a relationship between alcohol-related injury and subsequent injury death among predominately urban samples. The presence or nature of such a relationship has not been documented among American Indians living in the northern plains.

PURPOSE

The purpose of this study was to identify and characterize any association between prior injury and/or alcohol use contacts with the Indian Health Service (IHS) and subsequent alcohol-related injury death that may suggest opportunities for mitigation.

METHODS

Death certificates of American Indians who died from injury (ICD-9-E 800-999) in a rural IHS area over 6 consecutive years were linked to IHS acute-care facility records and toxicology reports. Deaths and prior IHS contacts were stratified by alcohol use as a contributing factor. Of the 526 injury deaths involving American Indians in the IHS area studied, 411 (78%) were successfully linked to IHS records. One hundred fifty-two of these cases met the inclusion criteria, with an additional 98 cases identified as a comparison group.

FINDINGS

No differences in alcohol use at time of death between groups with and without prior health care contact (for injury or alcohol) could be determined (81% vs 73%). A significant relationship was found between previous visits for acute or chronic alcohol use and subsequent alcohol-related fatalities (P =.01).

CONCLUSIONS

Based on these findings, injury-prevention activities in the population studied should be initiated at the time of any health-system contact in which alcohol use is identified. Intervention strategies should be developed that convey the immediate risk of death from injury in these patients.

Auto launch/early activation: a survey of AAMS members and literature review

BACKGROUND

Rapid access to definitive care is a fundamental tenet of trauma care and forms the basis for current emergency medical and trauma systems. Helicopters offer expedited transport to trauma centers and can deliver advanced practice personnel to the scene of injury, but many systems do not dispatch air medical crews until after assessment by ground providers.

OBJECTIVES

Here we report data from the AAMS Auto Launch Survey and perform a literature review.

METHODS

A 7-question survey was developed by the AAMS Research Committee and approved by the board. An invitation to participate in the survey was sent by electronic mail to all current members. A link to an online survey was included. Results were presented descriptively. Some respondents were willing to share auto launch protocols, which were categorized into patient-related factors, event-related factors, and geographic considerations.

RESULTS

A total of 86 usable responses were recorded, which represented about a third of the 240 total AAMS members. Of these, 38 respondents (44.2%) routinely use auto launch. Just over half of those using early activation reported using a combination of event- and patient-related considerations; most also incorporating geographic criteria. About one-third of respondents auto launch only at the request of ground personnel, and about one-quarter use geographic criteria alone. Threshold distances ranged from 20 to 25 miles or 20 to 30 minutes by ground.

CONCLUSIONS

About half of respondents routinely use auto launch, although protocols are not consistent. Auto launch appears to offer a mechanism for decreasing EMS response times, but additional research is needed to help define optimal dispatch criteria.

Hand-held thoracic sonography for detecting post-traumatic pneumothoraces: the Extended Focused Assessment with Sonography for Trauma (EFAST)

BACKGROUND

Thoracic ultrasound (EFAST) has shown promise in inferring the presence of post-traumatic pneumothoraces (PTXs) and may have a particular value in identifying occult pneumothoraces (OPTXs) missed by the AP supine chest radiograph (CXR). However, the diagnostic utility of hand-held US has not been previously evaluated in this role.

METHODS

Thoracic US examinations were performed during the initial resuscitation of injured patients at a provincial trauma referral center. A high frequency linear transducer and a 2.4 kg US attached to a video-recorder were used. Real-time EFAST examinations for PTXs were blindly compared with the subsequent results of CXRs, a composite standard (CXR, chest and abdominal CT scans, clinical course, and invasive interventions), and a CT gold standard (CT only). Charts were reviewed for in-hospital outcomes and follow-up.

RESULTS

There were 225 eligible patients (207 blunt, 18 penetrating); 17 were excluded from the US examination because of battery failure or a lost probe. Sixty-five (65) PTXs were detected in 52 patients (22% of patients), 41 (63%) being occult to CXR in 33 patients (14.2% whole population, 24.6% of those with a CT). The US and CXR agreed in 186 (89.4%) of patients, EFAST was better in 16 (7.7%), and CXR better in 6 (2.9%). Compared with the composite standard, the sensitivity of EFAST was 58.9% with a likelihood ratio of a positive test (LR+) of 69.7 and a specificity of 99.1%. Comparing EFAST directly to CXR, by looking at each of 266 lung fields with the benefit of the CT gold standard, the EFAST showed higher sensitivity over CXR (48.8% versus 20.9%). Both exams had a very high specificity (99.6% and 98.7%), and very predictive LR+ (46.7 and 36.3).

CONCLUSION

EFAST has comparable specificity to CXR but is more sensitive for the detection of OPTXs after trauma. Positive EFAST findings should be addressed either clinically or with CT depending on hemodynamic stability. CT should be used if detection of all PTXs is desired.

Fatal traumatic brain injury, West Virginia, 1989-1998

OBJECTIVE

The objective of this study was to describe fatal cases of traumatic brain injury (TBI) among West Virginia residents.

METHODS

The authors analyzed data from the National Center for Health Statistics Multiple Cause of Death tapes for the period 1989-1998. They compared West Virginia's annualized average TBI death rate with the rates of other states and with the rate among U.S. residents for the same period. U.S. Bureau of Census population estimates were used as denominators.

RESULTS

A total of 4,416 TBI deaths occurred in West Virginia in 1989-1998, for an annual average death rate of 23.6 per 100,000 population. From 1989 to 1998, TBI death rates declined 5% (p=0.4042). Seventy-five percent (n=3,315) of fatalities occurred among men. Adults > or =65 years of age accounted for the highest percentage of fatal injuries (n=1,135). The leading external causes of fatal TBI were: firearm-related (39% of reported fatalities), motor vehicles-related (34%), and fall-related (10%). Firearm-related TBI became the leading cause of TBI fatalities in 1991, surpassing motor vehicle-related TBI. Seventy-five percent of firearm-related TBI deaths were suicides (n=1,302). West Virginia's TBI death rate (23.6 per 100,000) was higher than the national rate (20.6 per 100,000). In 23 states, the average TBI death rates over the 10-year period were higher than West Virginia's. Whereas modest declines in TBI death rates occurred for motor vehicle-related and firearm-related causes in West Virginia, a concomitant 38% increase occurred in the fall-related TBI death rate during the decade.

CONCLUSION

Data presented in this report can be used to develop targeted prevention programs in West Virginia.

Pre-hospital and hospital traumatic deaths in the former homeland of Transkei, South Africa

This retrospective descriptive study on 274 medicolegal cases was to determine the issues related to pre-hospital and hospital deaths in injured patients and to determine whether any of the deaths were preventable in the area. Interviews of the family members were conducted individually before carrying out autopsies. Time of survival after trauma, place of death, and the cause of death were recorded along with the demographic information -- age, sex, occupation, and personal habits. Umtata General Hospital in the Eastern Cape Province is the referral hospital for a surrounding population of about 400,000. Seventy four percent (74%) of the victims had been declared, 'presumably dead' at the scene by the community or police, and taken to mortuary without any death certification by a physician. The rest (26%) were taken to hospital where later they succumbed to trauma. Out of these only 4% underwent surgery. The majority (68%) of the victims were young ( < 40 years). The causes of deaths were: motor vehicle accidents (MVA) 32%, gunshot 24%, stab injury 17%, blunt trauma 9% and miscellaneous (fall from height, burns, etc.) 17%. Head and chest injuries were the commonest 50%. Only 17% survived from days to weeks. About 75% subjects died within 6 h of the trauma. There is a very high pre-hospital (74%) mortality of trauma patients in the Transkei region. The fact that members of the community or police and not a medical practitioner confirmed deaths raises the ethical issue of right to life. Some may actually be alive when they are considered dead. As it appears that 12% of pre-hospital deaths are preventable, employing more medical personnel in the rural areas along with an effective ambulance service would seem to be required.

Rapid extrication from a car wreck

Extrication of entrapped patients from car accidents takes time. To save time a new technique based on reversing the forces of the original crash by anchoring the rear of the vehicle and pulling the steering wheel and the front window pillars forward with chains is developed. In an experimental randomised trial of extrication of volunteers from car wrecks after frontal/oblique impacts we wanted to evaluate the time spent with a new extrication technique (n=6) compared to standard (n=6). Main outcome measures were time to patient free and to patient on a stretcher. It took significantly longer (s) with the standard than the new technique to start extrication [(60 (45, 70) versus 30 (30, 40), confidence interval (CI) 5-40, P=0.009], to patient free in the front seat [514+/-102 versus 238+/-72, CI 163-389, P=0.001], backboard in place [543+/-102 versus 295+/-76, CI 132-363, P=0.001], and patient on the stretcher ready for transport to the hospital [617+/-112 versus 387+/-65, CI 112-347, P=0.001]. Avoiding uncontrolled movements in the wreck was not more difficult with the new than the standard technique.

Preparing teams for low-frequency emergencies in Norwegian hospitals

BACKGROUND

Medical emergencies and major trauma require optimal team function. Leadership, co-operation and communication are the most essential issues. Due to low caseloads such emergencies occur rarely in most Norwegian hospitals. Team training of personnel between real emergencies is expected to improve performance in comparable settings. Most hospitals have cardiac arrest teams, but it is known that the training of such multiprofessional teams varies widely. We wanted to know if this also was the case for trauma teams and resuscitation teams for newborns.

METHODS

A telephone survey of training practices in all the Norwegian hospitals with acute cover was conducted in 2002. Information was obtained on whether trauma teams and neonatal resuscitation teams had participated in practical multiprofessional training during the previous 6 or 12 months.

RESULTS

Information was obtained from all 50 hospitals. Of the acute care hospitals, 30% had trained their trauma teams during the previous 6 months, and an additional 18% when considering the previous year, while 38% of neonatal wards had multiprofessional training during the previous 6 months, and additionally 13% had had training during the previous year. Additionally four neonatal wards had had regular training of nurses only. More than 80% of all respondents judged regular team training to be achievable, and none considered this training impossible.

CONCLUSION

Only half the Norwegian acute care hospitals reported at least yearly training of trauma and neonatal resuscitation teams. Regular team training represents an underused potential to improve handling of low-frequency emergencies.

Effect of a voluntary trauma system on preventable death and inappropriate care in a rural state

BACKGROUND

This study compares the preventable death rate and the nature and degree of inappropriate care in a rural state before and after implementation of a voluntary trauma system.

METHODS

Deaths attributed to mechanical trauma occurring in the state of Montana between January 1, 1998, and December 31, 1998, were retrospectively reviewed by a multidisciplinary panel of physicians and nonphysicians representing the hospital and prehospital phases of care. Deaths were judged frankly preventable, possibly preventable, and nonpreventable. Care rendered in all categories was evaluated for appropriateness according to nationally accepted guidelines. Results were then compared with an identical study conducted before implementation of a voluntary trauma system. Measures to ensure comparability of the two studies were taken.

RESULTS

Three hundred forty-seven (49%) of all trauma-related deaths met review criteria. The overall preventable death rate (PDR) was 8%. In those patients surviving to be treated at a hospital, the PDR was 15%. The overall rate of inappropriate care was 36%, 22% prehospital and 54% in-hospital. The majority of inappropriate care in all phases of care revolved around airway and chest injury management. The emergency department (ED) was the phase of care in which the majority of deficiencies were noted. In comparison with the results of the earlier study, PDR decreased (8% vs. 13%, p < 0.02). Adjusted rates of inappropriate care also showed a decrease (prehospital, 22% vs. 37%; ED, 40% vs. 68%; post-ED, 29% vs. 49%); however, the nature of deficiencies was the same. Population characteristics influencing interpanel reliability were similar for the two groups compared. Agreement on test cases presented to both panels was good (kappa statistic, 0.8).

CONCLUSION

Implementation of a voluntary trauma system has positive effects on PDR and inappropriate care. The degree and nature of inappropriate care remain a concern. Mandated and funded system policies may further influence care positively.

Death after injury in rural Norway: high rate of mortality and prehospital death

BACKGROUND

Finnmark is a rural and remote area in Norway with a sparse population and long distances. Trauma-related mortality has been consistently above the Norwegian national average for the last 20 years. Although the causes of death are well established, very little is known about the time and place of death. This information has implications for the organization of emergency services in rural areas. We examined all trauma deaths over a five-year period in order to inform the debate on how best to reduce our above-average mortality rate.

METHODS

A retrospective study of all deaths after trauma (ICD-9 E800-E999) during the years 1991-95 using data obtained from the National Registry of Death.

RESULTS

Of the 183 cases found, 130 deaths were due to trauma using definitions comparable to similar studies. The mortality rate was 77 per 100,000 inhabitants per year. Death occurred in the prehospital phase in 85% of cases. Seventy-two per cent of all deaths (regardless of location) occurred within the first h after injury, eight per cent from 1 to 4 h and the remaining 20% occurred after 4 h.

CONCLUSION

When planning interventions to reduce the mortality rate from trauma in rural areas, a high proportion of prehospital deaths should be expected. The high number of patients who are found dead (which can only be reduced by injury prevention) must be taken into account. Measures to reduce 'preventable' causes of death by bystanders should be evaluated. Further knowledge of exact mechanisms of death in the prehospital phase is required.

Motor vehicle crash-related mortality is associated with prehospital and hospital-based resource availability

BACKGROUND

To date, attempts to assess the relationship between motor vehicle collision (MVC)-related mortality and medical resources availability have largely been unsuccessful.

METHODS

Information regarding sociodemographic characteristics, prehospital resources, and hospital-based resources for each county (n = 67) in the state of Alabama was obtained. MVC-related mortality rates (deaths per 1,000 collisions) by county were calculated and compared according to prehospital and hospital-based resource availability within each county after correcting for sociodemographic factors.

RESULTS

Counties with 24-hour availability of a general surgeon, orthopedic surgeon, neurosurgeon, computed tomographic scanner, and operating room were shown to have decreased MVC-related mortality (relative risk [RR], 0.88). The same was true for those counties with hospitals classified as Level I-II (RR, 0.71) and Level III-IV (RR, 0.83) trauma centers compared with counties with no trauma centers.

CONCLUSION

Appropriate, readily available hospital-based resources are associated with lower MVC-related mortality rates. This information may be useful in trauma system planning and development.
