Overtriage of transfers to the pediatric trauma center: the importance of minor head injury

OBJECTIVE

Accurate triage of minor head injuries remains a challenge for mature trauma systems. More than one-third of trauma transfers are overtriaged, and minor head injuries predominate. Overtriage is inefficient, wasteful of resources, and burdensome for families. The authors studied overtriage at the sole level I pediatric trauma center (PTC) in a small state with a view toward improvement of processes.

METHODS

Data on transfer patients were extracted from an institutional trauma registry over an 8-year period. Three definitions of overtriage were examined: one based on transfer criteria from the American College of Surgeons Committee on Trauma, one based on resource utilization, and one adapted to the regional environment of the PTC. Associations of demographic, geographic, clinical, and social factors with overtriage were examined.

RESULTS

There were 1754 unique patients transferred from the emergency departments (EDs) of other institutions to the PTC. Thirty-six percent of transfers were overtriaged by all 3 criteria, and 23% of all transfers were minor head injuries overtriaged by all criteria. Infants were more likely to be overtriaged than other age groups. Among racial categories, Black patients were least likely to be overtriaged. Patients with commercial insurance were more likely to be overtriaged. Overtriaged patients averaged shorter trips from the referring ED to the PTC, even though the PTC was farther from their homes. These observations suggest a sensitivity to social expectations in the exercise of ED physician judgments about transfer.

CONCLUSIONS

More than one-third of all transfers to the study PTC were overtriaged, and almost one-quarter of all transfers were overtriaged minor head injuries. Minor head injuries are a potentially rewarding focus for system-wide quality improvement, but the interplay of social factors with ED physician judgments must be recognized.

Access to Trauma Care in a Rural State: A Descriptive Geographic and Demographic Analysis

BACKGROUND

Montana is a rural state with limited access to higher-level trauma care; it also has higher injury fatality rates compared with the rest of the country.

OBJECTIVES

The purpose of this study was to utilize Geographic Information System methodology to assess proximity to trauma care and identify the demographic characteristics of regions without trauma access.

METHODS

Maptitude® Geographic Information System software (Caliper Corporation, Newton, MA) was used to identify regions in Montana within 60 min of trauma care; this included access to a Level II or Level III trauma center with general surgery capabilities and access to any level of trauma care. Demographic characteristics are reported to identify population groups lacking access to trauma care.

RESULTS

Of the 1.1 million residents of Montana, 63% of residents live within 60 driving min of a higher-level trauma center, and 83% of residents live within 60 driving min of any level of trauma center. Elderly residents over age 65 years of age and American Indians had reduced access to both higher-level trauma care and any level trauma care.

CONCLUSIONS

Prompt access to trauma care is significantly lower in Montana than in other parts of the country, with dramatic disparities for American Indians. In a rural state, it is important to ensure that all hospitals are equipped to provide some level of trauma care to reduce these disparities.

Trauma Quality Improvement Program: A Retrospective Analysis from A Middle Eastern National Trauma Center

BACKGROUND

The Trauma Quality Improvement Program (American College of Surgery (ACS-TQIP)) uses the existing infrastructure of the Committee on Trauma programs and provides feedback to participating hospitals on risk-adjusted outcomes. This study aimed to analyze and compare the performance of the Level I Hamad Trauma Centre (HTC) with other TQIP participating centers by comparing TQIP aggregate database reports. The primary goal was to pinpoint the variations in adult trauma outcomes and quality measures, identify areas that need improvement, and leverage existing resources to facilitate quality improvement.

METHODS

A retrospective analysis was performed for the TQIP data from April 2019-March 2020 to April 2020-March 2021. We used the TQIP methodology, inclusion and exclusion criteria, and outcomes.

RESULTS

There were 915 patients from Fall 2020 and 884 patients from Fall 2021 that qualified for the TQIP database. The HTC patients' demographics differed from the TQIP's aggregate data; they were younger, more predominantly male, and had significantly different mechanisms of injury (MOI) with more traffic-related blunt trauma. Penetrating injuries were more severe in the other centers. During the TQIP Fall 2020 report, the HTC was a low outlier (good performer) in one cohort (all patients) and an average performer in the remaining cohorts. However, during Fall 2021, the HTC showed an improvement and was a low outlier in two cohorts (all patients and severe TBI patients). Overall, the HTC remained an average performer during the report cycles.

CONCLUSIONS

There was an improvement over time in the risk-adjusted mortality, which reflects the continuous and demanding effort put together by the trauma team. The ACS-TQIP for the external benchmarking of quality improvement could be a contributor to better monitored patient care. Evaluating the TQIP data with emphases on appropriate methodologies, quality measurements, corrective measures, and accurate reporting is warranted.

Trauma system establishment and outcome improvement: a retrospective national cohort study in South Korea

BACKGROUND

Trauma is a major cause of mortality, disability, and health care costs worldwide. The establishment of a trauma system is known to solve these problems, but few studies have objectively evaluated the impact of a trauma system on outcomes. Since 2012, South Korea has established a national trauma system based on the implementation of 17 regional trauma centers nationwide and the improvement of the prehospital transfer system. This study aimed to measure the changes in performance and outcome according to the established national trauma system.

MATERIAL AND METHODS

In this national cohort-based, retrospective follow-up observational study, the authors calculated the preventable trauma death rate (PTDR) by conducting a multipanel review of patients who died in 2015, 2017, and 2019. Furthermore, the authors constructed a risk-adjusted mortality prediction model of 4 767 876 patients between 2015 and 2019 using the extended-International Classification of Disease Injury Severity Scores to compare outcomes.

RESULTS

The PTDR was lower in 2019 than in 2015 (15.7 vs. 30.5, P <0.001) and 2017 (15.7 vs. 19.9%, P <0.001) representing 1247 additional lives saved in 2019 compared to that in 2015. In the risk-adjusted model, total trauma mortality was highest in 2015 at 0.56%, followed by that in 2016 and 2017 (0.50%), 2018 (0.51%), and 2019 (0.48%), revealing a significant decrease in mortality over the years ( P <0.001 for trend), representing nearly 800 additional lives saved. The number of deaths for more severe patients with a probability of survival less than 0.25 significantly decreased from 81.50% in 2015 to 66.17% in 2019 ( P <0.001).

CONCLUSIONS

The authors observed a significant reduction in the PTDR and risk-adjusted trauma mortality in the 5-year follow-up since 2015 when the national trauma system was established. These findings could serve as a model for low-income and middle-income countries, where trauma systems are not yet established.

Challenges to the development of the trauma system in Egypt

Trauma is a hidden disease in Egypt, and its significance on public health has been underestimated for decades. Road traffic accidents are the leading cause of injuries presented to hospitals in Egypt. Trauma systems in developed countries effectively reduced the morbidity and mortality associated with injuries in crowded cities. Developing a trauma system in Egypt is mandatory with the exploding population growth, increasing incidence of injuries, and the vast expansion of the infrastructures in the road network. However, the implementation of the trauma system in Egypt will not be devoid of challenges, including a lack of mandatory healthcare infrastructures such as adequate pre-hospital care, poor quality of data, and a shortage of adequately trained emergency physicians across the country.

Pre- and posttransfer computed tomography imaging in Canadian trauma centers: A multicenter retrospective cohort study

BACKGROUND

Multiple clinical practice guidelines recommend minimizing radiation in trauma patients but there is a knowledge gap on the importance of this problem for trauma transfers. We aimed to estimate the incidence of pretransfer and repeat posttransfer computed tomography (CT) overall and in patients with an indication for immediate transfer, to assess interhospital practice variation, to identify predictors, and to quantify the influence of pretransfer CT on time to transfer. Methods We conducted a retrospective multicenter cohort study on patients transferred to major trauma centers from 2013 to 2019. Multilevel generalized linear regression was used to generate intraclass correlation coefficients (ICCs) to assess interhospital variation, multilevel logistic regression to generate odds ratios for each predictor, and geometric mean ratios to quantify the influence of CT on time to transfer. Results Of 18,244 patients included, 8501 (47%) had a pretransfer CT and one-quarter (26%) had a repeat posttransfer CT. Interhospital variation was moderate for pretransfer CT (5%-66%, ICC 12.5%) and for repeat posttransfer CT (7%-44%, ICC 14.7%). Pretransfer imaging was more frequent in elders and in males and repeat posttransfer imaging decreased over the study period but was more frequent in patients transferred in from Level III/IV centers than nondesignated hospitals. Time to transfer was doubled in patients who had a pretransfer CT.

CONCLUSIONS

Results suggest that pretransfer CT and repeat posttransfer CT are frequent and are subject to significant practice variation. In addition, pretransfer CT is associated with increased times to transfer though additional studies are needed to demonstrate causation. These results highlight potential opportunities to reduce low-value imaging for trauma transfers.

Perceived usefulness of trauma audit filters in urban India: a mixed-methods multicentre Delphi study comparing filters from the WHO and low and middle-income countries

OBJECTIVE

To compare experts' perceived usefulness of audit filters from Ghana, Cameroon, WHO and those locally developed; generate context-appropriate audit filters for trauma care in selected hospitals in urban India; and explore characteristics of audit filters that correlate to perceived usefulness.

DESIGN

A mixed-methods approach using a multicentre online Delphi technique.

SETTING

Two large tertiary hospitals in urban India.

METHODS

Filters were rated on a scale from 1 to 10 in terms of perceived usefulness, with the option to add new filters and comments. The filters were categorised into three groups depending on their origin: low and middle-income countries (LMIC), WHO and New (locally developed), and their scores compared. Significance was determined using Kruskal-Wallis test followed by Wilcoxon rank-sum test. We performed a content analysis of the comments.

RESULTS

26 predefined and 15 new filter suggestions were evaluated. The filters had high usefulness scores (mean overall score 9.01 of 10), with the LMIC filters having significantly higher scores compared with those from WHO and those newly added. Three themes were identified in the content analysis relating to medical relevance, feasibility and specificity.

CONCLUSIONS

Audit filters from other LMICs were deemed highly useful in the urban India context. This may indicate that the transferability of defined trauma audit filters between similar contexts is high and that these can provide a starting point when implemented as part of trauma quality improvement programmes in low-resource settings.

Development of the Saudi Arabian trauma system

A dedicated network-based trauma system ensures optimal care to injured patients. Considering the significant burden of trauma, the Kingdom of Saudi Arabia is striving to develop a nationwide trauma system. This article describes the recent design, development, and implementation of the Saudi Arabian trauma system in line with Vision 2030. The basis of our strategy was the find, organize, clarify, understand, select-plan, do, check, and act (FOCUS-PDCA) model, developed by engaging key stakeholders, including patients. More than 300 healthcare professionals and patients from around the Riyadh region assessed the current system with three solutions and roadmap workshops. Subsequently, the national clinical advisory group (CAG) for trauma was formed to develop the Saudi Arabian trauma system, and CAG members analyzed and collated internationally recognized trauma systems and guidelines. The guidelines' applicability in the kingdom was discussed and reviewed, and an interactive document was developed to support socialization and implementation. The CAG team members agreed on the guiding principles for the trauma pathway, identified the challenges, and finalized the new system design. They also developed a trauma care standard document to support and guide the rollout of new trauma networks across the kingdom. The CAG members and other stakeholders are at the forefront of implementing the trauma system across the Riyadh region. Recent trauma system development in Saudi Arabia is the first step in improving national trauma care and may guide development in other locations, regionally and internationally, to improve outcomes.

Trauma Team Activation: Which Surgical Capability Is Immediately Required in Polytrauma? A Retrospective, Monocentric Analysis of Emergency Procedures Performed on 751 Severely Injured Patients

There has been an ongoing discussion as to which interventions should be carried out by an “organ specialist” (for example, a thoracic or visceral surgeon) or by a trauma surgeon with appropriate general surgical training in polytrauma patients. However, there are only limited data about which exact emergency interventions are immediately carried out. This retrospective data analysis of one Level 1 trauma center includes adult polytrauma patients, as defined according to the Berlin definition. The primary outcome was the four most common emergency surgical interventions (ESI) performed during primary resuscitation. Out of 1116 patients, 751 (67.3%) patients (male gender, 530, 74.3%) met the inclusion criteria. The median age was 39 years (IQR: 25, 58) and the median injury severity score (ISS) was 38 (IQR: 29, 45). In total, 711 (94.7%) patients had at least one ESI. The four most common ESI were the insertion of a chest tube (48%), emergency laparotomy (26.3%), external fixation (23.5%), and the insertion of an intracranial pressure probe (ICP) (19.3%). The initial emergency treatment of polytrauma patients include a limited spectrum of potential life-saving interventions across distinct body regions. Polytrauma care would benefit from the 24/7 availability of a trauma team able to perform basic potentially life-saving surgical interventions, including chest tube insertion, emergency laparotomy, placing external fixators, and ICP insertion.

Right Patient, Right Place, Right Time : Field Triage and Transfer to Level I Trauma Centers

INTRODUCTION

This study sought to compare outcomes of trauma patients taken directly from the field to a Level I trauma center (direct) versus patients that were first brought to a Level III trauma center prior to being transferred to a Level I (transfer) within our inclusive Delaware trauma system.

METHODS

A retrospective review of the Level I center's trauma registry was performed using data from 2013 to 2017 for patients brought to a single Level I trauma center from 2 surrounding counties. The direct cohort consisted of 362 patients, while the transfer cohort contained 204 patients. Linear regression analysis was performed to investigate hospital length of stay (LOS), while logistic regression was used for mortality, complications, and craniotomy. Covariates included age, gender, county, and injury severity score (ISS). Propensity score weighting was also performed between the direct and transfer cohorts.

RESULTS

When adjusting for age, gender, ISS, and county, transferred patients demonstrated worse outcomes compared with direct patients in both the regression and propensity score analyses. Transferred patients were at increased risk of mortality (odds ratio [OR] 2.17, CI 1.10-4.37, P = .027) and craniotomy (OR 3.92, CI 1.87-8.72, P < .001). Age was predictive of mortality (P < .001). ISS was predictive of increased risk of mortality (P < .001), increased LOS (P < .001), and craniotomy (P < .001). Older age, Sussex County, and higher ISS were predictive of patients being transferred (P < .001).

DISCUSSION

Delays in the presentation to our Level I trauma center resulted in worse outcomes. Patients that meet criteria should be considered for transport directly to the highest level trauma center in the system to avoid delays in care.

Quantification of Trauma Center Access Using Geographical Information System-Based Technology

OBJECTIVES

There is no generally accepted methodology to assess trauma system access. The goal of this study is to determine the influence of the number and geographical distribution of trauma centers (TCs) on transport times (TT) using geographic information system (GIS)-technology.

METHODS

Using ArcGIS-PRO, we calculated differences in TT and population coverage in 7 scenarios with 1, 2, or 3 TCs during rush (R) and low-traffic (L) hours in a densely populated region with 3 TCs in the Netherlands.

RESULTS

In all 7 scenarios, the population that could reach the nearest TC within <45 minutes varied between 96% and 99%. In the 3-TC scenario, roughly 57% of the population could reach the nearest TC <15 minutes both during R and L. The hypothetical geographically well-spread 2-TC scenario showed similar results as the 3-TC scenario. In the 1-TC scenarios, the population reaching the nearest TC <15 minutes decreased to between 19% and 32% in R and L. In the 3-TC scenario, the average TT increased by about 1.5 minutes to almost 21 minutes during R and 19 minutes during L. Similar results were seen in the scenarios with 2 geographically well-spread TCs. In the 1-TC scenarios and the less well-spread 2-TC scenario, the average TT increased by 5 to 8 minutes (L) and 7 to 9 minutes (R) compared to the 3-TC scenario.

CONCLUSIONS

This study shows that a GIS-based model offers a quantifiable and objective method to evaluate trauma system access under different potential trauma system configurations. Transport time from accident to TC would remain acceptable, around 20 minutes, if the current 3-TC situation would be changed to a geographically well-spread 2-center scenario.

A System That Uses Advanced Automatic Collision Notification Technology to Dispatch Doctors to Traffic Accidents by Helicopter: The First 4 Cases

INTRODUCTION

To increase survival rates of patients with severe trauma from road traffic accidents, Japan launched the D-Call Net (DCN) system, which utilizes advanced automatic collision notification technology to dispatch doctors by helicopter. The DCN system began in November 2015 and, as of October 2019, has dispatched doctors 4 times.

CASES

Case 1-Canceled because trauma was mild. Case 2-Doctor made contact with 2 patients with moderate trauma 29 minutes earlier than would have occurred conventionally. This was the first case in the world to use automotive engineering data to dispatch a doctor to a patient. Case 3-An accident involving 3 severely injured patients activated DCN, enabling doctor-patient contact 20 minutes earlier than would have been possible conventionally. Case 4-DCN was ineffective.

DISCUSSION

According to 2008 data from Chiba Prefecture, in accidents where victims sustain severe trauma, the interval from accident occurrence to hospital arrival was 67 minutes, even when doctors were dispatched by air ambulance (Doctor-Heli [DH]). Use of accident information for faster doctor dispatch effectively improved survival rates. An algorithm was developed to use accident information to assess trauma severity (severity probability). DCN dispatches doctors by using data, including information on accident site and severity probability, which are sent to smartphones of doctors, thereby reducing the interval from accident to DH request by approximately 17 minutes. DCN is the first system in the world to use automotive engineering information for faster doctor dispatch to traffic accident sites. The system is crucial for improving survival rates and mitigating the aftereffects of traffic accidents.

Distribution of Trauma Deaths in a Province of Korea: Is "Trimodal" Distribution Relevant Today?

PURPOSE

This study was designed to provide a basis for building a master plan for a regional trauma system by analyzing the distribution of trauma deaths in the most populous province in Korea.

MATERIALS AND METHODS

We investigated the time distribution to death for trauma patients who died between January and December 2017. The time distribution to death was categorized into four groups (within a day, within a week, within a month, and over a month). Additionally, the distribution of deaths within 24 hours was further analyzed. We also reviewed the distribution of deaths according to the cause of death and mechanism of injury.

RESULTS

Of the 1546 trauma deaths, 328 cases were included in the final study population. Patients who died within a day were the most prevalent (40.9%). Of those who died within a day, the cases within an hour accounted for 40.3% of the highest proportion. The majority of trauma deaths within 4 hours were caused by traffic-related accidents (60.4%). The deaths caused by bleeding and central nervous system injuries accounted for most (70.1%) of the early deaths, whereas multi-organ dysfunction syndrome/sepsis had the highest ratio (69.7%) in the late deaths. Statistically significant differences were found in time distribution according to the mechanism of injury and cause of death (p<0.001).

CONCLUSION

The distribution of overall timing of death was shown to follow a bimodal pattern rather than a trimodal model in Korea. Based on our findings, a suitable and modified trauma system must be developed.

International technical transfer of training systems and skills in emergency medicine and trauma management: experiences of the National Center for Global Health and Medicine, Japan

For over 20 years, the National Center for Global Health and Medicine (NCGM), Japan has been involved in international assistance for emergency medicine and trauma management in many countries, including Bolivia, Vietnam, Laos, Cambodia, and Mongolia. Among the NCGM activities conducted, the most important is technical assistance for the appropriate transfer of training systems and skills in life support management. In most of the target countries, the development and execution of customized simulation training suitable for each setting has successfully motivated trainees, who are healthcare workers responsible for improving emergency medical services in their home country. Moreover, the development of appropriate training systems for trainers selected from among capable participants has played a key role in the subsequent sustained conducting of training courses independent of NCGM involvement.

Protocol for a feasibility exploratory multicentre study of factors influencing trauma patients' outcomes of traffic crashes in Saudi Arabia

INTRODUCTION

Road traffic injury is a leading cause of death for people of all ages. The burden of road traffic injuries is well established in developed countries. However, there has been limited investigation of the incidence and burden of road traffic injury in low/middle-income countries. With a proportionally high number of road users, there is a need to explore the factors in prehospital and hospital care in Saudi Arabia (SA) that are associated with mortality for adult trauma patients following road traffic crashes (RTCs). This paper outlines the method for the planned research.

METHODS AND ANALYSIS

A feasibility exploratory multicentre study will be conducted at three purposefully selected hospitals with different trauma care resources in differing geographic locations of SA. The study sample will include all adult trauma patients who are involved in RTCs in SA and have been admitted to a study site in a 3-month period from May to July 2019. Data regarding the characteristics of the crashes and prehospital health care factors will be extracted from hospital databases where it is available. Information will be collected from patients or carers and hospital records in the two sites that do not have a registry. Patient status at 30 days post-injury, particularly mortality, will be assessed through hospital records. The relative contribution of a range of factors to predicting mortality will be explored using logistic regression analysis.

ETHICS AND DISSEMINATION

This study was approved by the Institutional Review Board Committee at King Saud Medical City (H-01-R-053), the General Department of Research and Studies at the Ministry of Health in SA (1440-1249939) and (1440-1398648), and the La Trobe University Human Research Ethics Committee (HEC19095). The results will be reported in a thesis and in peer-reviewed journal articles and conference presentations.

Helicopter Critical Care Retrieval in a Developing Country: A Trauma Case Series from Bhutan

Background: The care of victims of traumatic injuries requires an organized system to achieve the best outcomes. Dispatch of specialist physicians, paramedics, and nurses to the patient by helicopter can reduce mortality. Countries in the developing world share the challenge of providing timely medical care to trauma victims, while facing others such as a higher trauma burden, poor infrastructure, inadequate government resources, organizational constraints, a lack of technical expertise, and prohibitive costs. These challenges can severely limit the provision of critical prehospital trauma care. Methods: We reviewed the prehospital trauma database to identify victims of trauma who required aeromedical evacuation as determined by the national triage system of Bhutan during the 4-month period after the establishment of the national Bhutan Emergency Aeromedical Retrieval (BEAR) team. We collected the patients' age and gender, description of injuries, mechanism of injury, interventions undertaken by the critical care retrieval team, and patient outcomes (alive vs. dead). Results: During the first 4 months of service, BEAR cared for 16 trauma patients. Fourteen patients survived to hospital discharge; two died after hospitalization. No patient died on scene or during transport. The team successfully treated several challenging casualties, including a patient gored by a water buffalo leading to traumatic cardiac arrest with successful resuscitation, victims of a compressed gas cylinder explosion, a bear mauling, and a penetrating arrow injury to the head. The team performed a variety of critical care interventions, including induction and maintenance of anesthesia, orotracheal intubation, mechanical ventilation, tube thoracostomy, administration of blood products, and successful management of traumatic cardiac arrest. Conclusion: A critical care helicopter retrieval team can deliver trauma care in a developing country, such as Bhutan, with favorable outcomes at low cost.

Prehospital and Emergency Care in Adult Patients with Acute Traumatic Brain Injury

Traumatic brain injury (TBI) is a major healthcare problem and a major burden to society. The identification of a TBI can be challenging in the prehospital setting, particularly in elderly patients with unobserved falls. Errors in triage on scene cannot be ruled out based on limited clinical diagnostics. Potential new mobile diagnostics may decrease these errors. Prehospital care includes decision-making in clinical pathways, means of transport, and the degree of prehospital treatment. Emergency care at hospital admission includes the definitive diagnosis of TBI with, or without extracranial lesions, and triage to the appropriate receiving structure for definitive care. Early risk factors for an unfavorable outcome includes the severity of TBI, pupil reaction and age. These three variables are core variables, included in most predictive models for TBI, to predict short-term mortality. Additional early risk factors of mortality after severe TBI are hypotension and hypothermia. The extent and duration of these two risk factors may be decreased with optimal prehospital and emergency care. Potential new avenues of treatment are the early use of drugs with the capacity to decrease bleeding, and brain edema after TBI. There are still many uncertainties in prehospital and emergency care for TBI patients related to the complexity of TBI patterns.

Evolution of The Qatar Trauma System: The Journey from Inception to Verification

Traumatic injuries accounted for substantial burden of morbidity and mortality (M and M) worldwide. Despite better socioeconomic conditions and living standards, the incidence of trauma is rising in the Eastern Mediterranean Region (EMR). Road traffic injuries are the leading cause of the high fatality rate in young economically productive adults in our region. The provision of trauma care at high-volume, accredited trauma center by a team of dedicated full-time professional health-care providers has been shown to improve the quality of care and the outcomes for trauma victims. With persistent hard work and effective leadership, in Qatar, the Trauma Section has evolved into a well-reputed and internationally recognized Center of Excellence in Trauma Care, Hamad Level 1 Trauma Center. In 2014, Qatar Trauma System was accredited with Trauma Distinction Award by the Accreditation Canada International, for high-quality trauma care of severely injured patients; first in the Middle East. The Hamad Trauma Center is committed to the advancement of trauma care in different aspects right from the immediate prehospital care to the subsequent hospital-based care, involving diagnosis, treatment, support, rehabilitation, and community reintegration of the patients and injury prevention. Our trauma system has gradually embedded with a structured and matured research unit with dedicated clinicians and academic researchers. The trauma team embodies the 21^st-century paradigm of translational research and injury prevention by going well beyond the bedside, out into the populations that need it most. The trauma system's future vision relies on the evidence-based health-care service and better outcomes; state-of-the-art infrastructure and multidimensional collaborations with health care and governmental services to minimize the burden of M and M caused by traumatic injury in the State of Qatar and to fulfill the population health enhancement strategy.

Principles of system design not realized for pediatric craniospinal trauma care in the United States

OBJECTIVE An implicit expectation of the pioneers of trauma system design was that high clinical volume at select centers could lead to superior outcomes. There has been little study of the regionalization of pediatric craniospinal trauma care, and whether it continues to trend in the direction of regionalization is unknown. The motivating hypothesis for this study was that trauma system design in the United States is proceeding on a rational basis, producing hospital caseloads that are increasing over time and, because of geographic siting appropriate to the needs of catchment areas, in an increasingly uniform manner. METHODS Data were obtained from the Kids' Inpatient Database (KID) for 1997, 2000, 2003, 2006, 2009, and 2012. Cases of traumatic spinal injury (TSI) and severe traumatic brain injury (sTBI) were identified by ICD-9 diagnostic and procedural codes. Records of patients 18 years of age and older were excluded. Hospital caseloads and descriptive statistics were calculated for each year of the study, and trends were examined. The distributions of hospital caseloads were compared year with year and with simulations of idealized systems. RESULTS Caseloads of TSI trended upward and caseloads of sTBI were stable, despite a declining nationwide incidence of these conditions during the study period, so the pool of hospitals providing services for pediatric craniospinal trauma contracted to a degree. The distributions of hospital caseloads did not change, and in every year of the study large numbers of hospitals reported small numbers of discharges. In the last year of the study, a quarter of all children with TSI were discharged from hospitals that treated approximately 1 case or fewer every other month and a quarter of all children with sTBI were discharged from hospitals that treated 1 case or fewer every 3 months. CONCLUSIONS There has been no previous study of nationwide trends in pediatric craniospinal trauma caseloads. Analysis of hospital caseloads from 1997 through 2012 supports inference of a persisting geographical mismatch between population needs and the availability of services. These observations falsify the study hypothesis. A notable fraction of pediatric craniospinal trauma care continues to be rendered at low-caseload institutions. Novel quality assurance methods tailored to the needs of low-caseload institutions deserve development and study.

Hospital trauma level's association with outcomes for injured pregnant women and their neonates in Washington state, 1995-2012

Background:

Trauma occurs in 8% of all pregnancies. To date, no studies have evaluated the effect of the hospital's trauma designation level as it relates to birth outcomes for injured pregnant women.

Methods:

This population-based, retrospective cohort study evaluated the association between trauma designation levels and injured pregnancy birth outcomes. We linked Washington State Birth and Fetal Death Certificate data and the Washington State Comprehensive Hospital Abstract Recording System. Injury was identified using the International Classification of Diseases, Ninth Revision injury diagnosis and external causation codes. The association was analyzed using logistic regression to estimate odds ratios and 95% confidence intervals (CIs).

Results:

We identified 2492 injured pregnant women. Most birth outcomes studied, including placental abruption, induction of labor, premature rupture of membranes, cesarean delivery, maternal death, gestational age <37 weeks, fetal distress, fetal death, neonatal respiratory distress, and neonatal death, showed no association with trauma hospital level designation. Patients at trauma Level 1–2 hospitals had a 43% increased odds of preterm labor (95% CI: 1.15–1.79) and a 66% increased odds of meconium at delivery (95% CI: 1.05–2.61) compared to those treated at Level 3–4 hospitals. Patients with an injury severity score >9, treated at trauma Level 1–2 hospitals, had an aOR of low birth weight, <2500 g, of 2.52 (95% CI: 1.12–5.64).

Conclusions:

The majority of birth outcomes for injured patients had no association with hospitalization at a Level 1–2 compared to a Level 3–4 trauma center.

How motorcycle helmets affect trauma mortality: Clinical and policy implications

BACKGROUND

Motorcycles are the most popular vehicles in Taiwan, where more than 14.8 million motorcycles (1 motorcycle per 1.6 people) are in service. Despite the mandatory helmet law passed in 1997, less than 80% of motorcyclists in Taiwan wear helmets.

OBJECTIVE

The objective of this study was to analyze the effect of using motorcycle helmets on fatality rates.

METHODS

A clinical data set including 2,868 trauma patients was analyzed; the cross-sectional registration database was administered by a university medical center in Central Taiwan. A path analysis framework and multiple logistic regressions were used to estimate the marginal effect of helmet use on mortality.

RESULTS

Using a helmet did not directly reduce the mortality rate but rather indirectly reduced the mortality rate through intervening variables such as the severity of head injuries, number of craniotomies, and complications during therapeutic processes. Wearing a helmet can reduce the fatality rate by 1.3%, the rate of severe head injury by 34.5%, the craniotomy rate by 7.8%, and the rate of complications during therapeutic processes by 1.5%. These rates comprise 33.3% of the mortality rate for people who do not wear helmets, 67.3% of the severe head injury rate, 60.0% of the craniotomy rate, and 12.2% of the rate of complications during therapeutic processes.

DISCUSSION

Wearing a helmet and trauma system designation are crucial factors that reduce the fatality rate.

Models of care for traumatically injured patients at trauma centres in British Columbia: variability and sustainability

BACKGROUND

Successful trauma systems employ a network of variably-resourced hospitals, staffed by experienced providers, to deliver optimal care for injured patients. The "model of care"-the manner by which inpatients are admitted and overseen, is an important determinant of patient outcomes.

OBJECTIVES

To describe the models of inpatient trauma care at British Columbia's (BC's) ten adult trauma centres, their sustainability, and their compatibility with accreditation guidelines.

METHODS

Questionnaires were distributed to the trauma medical directors at BC's ten Level I-III adult trauma centres. Follow-up semi-structured interviews clarified responses.

RESULTS

Three different models of inpatient trauma care exist within BC. The "admitting trauma service" was a multidisciplinary team providing exclusive care for injured patients. The "on-call consultant" assisted with Emergency Department (ED) resuscitation before transferring patients to a non-trauma admitting service. The single "short-stay trauma unit" employed on-call consultants who also oversaw a 48-hour short-stay ward. Both level I trauma centres utilized the admitting trauma service model (2/2). All Level II sites employed an on-call consultant model (3/3), deviating from Level II trauma centre accreditation standards. Level III sites employed all three models in similar proportions. None of the on-call consultant sites believed their current care model was sustainable. Inadequate compensation, insufficient resources, and difficulty recruiting physicians were cited barriers to sustainability and accreditation compliance.

CONCLUSIONS

Three distinct models of care are distributed inconsistently across BC's Level I-III trauma hospitals. Greater use of admitting trauma service and short-stay trauma unit models may improve the sustainability and accreditation compliance of our trauma system.

Does prehospital time affect survival of major trauma patients where there is no prehospital care?

BACKGROUND

Survival after major trauma is considered to be time dependent. Efficient prehospital care with rapid transport is the norm in developed countries, which is not available in many lower middle and low-income countries. The aim of this study was to assess the effect of prehospital time and primary treatment given on survival of major trauma patients in a setting without prehospital care.

MATERIALS AND METHODS

This prospective observational study was carried out in a university hospital in Mumbai, from January to December 2014. The hospital has a trauma service but no organized prehospital care or defined interhospital transfer protocols. All patients with life- and/or limb-threatening injuries were included in the study. Injury time and arrival time were noted and the interval was defined as "prehospital time" for the directly arriving patients and as "time to tertiary care" for those transferred. Primary outcome measure was in-hospital death (or discharge).

RESULTS

Of 1181 patients, 352 were admitted directly from the trauma scene and 829 were transferred from other hospitals. In-hospital mortality was associated with age, mechanism and mode of injury, shock, Glasgow Coma Score <9, Injury Severity Score ≥16, need for intubation, and ventilatory support on arrival; but neither with prehospital time nor with time to tertiary care. Transferred patients had a significantly higher mortality (odds ratio = 1.869, 95% confidence interval = 1.233-2.561, P = 0.005) despite fewer patients with severe injury. Two hundred and ninety-four (35%) of these needed airway intervention while 108 (13%) needed chest tube insertion on arrival to the trauma unit suggesting inadequate care at primary facility.

CONCLUSION

Mortality is not associated with prehospital time but with transfers from primary care; probably due to deficient care. To improve survival after major trauma, enhancement of resources for resuscitation and capacity building of on-duty doctors in primary centers should be a priority in countries with limited resources.

Delivery as Trauma: A Prospective Time-Cohort Study of Maternal and Perinatal Mortality in Rural Cambodia

OBJECTIVE

The majority of maternal and perinatal deaths are preventable, but still women and newborns die due to insufficient Basic Life Support in low-resource communities. Drawing on experiences from successful wartime trauma systems, a three-tier chain-of-survival model was introduced as a means to reduce rural maternal and perinatal mortality.

METHODS

A study area of 266 villages in landmine-infested Northwestern Cambodia were selected based on remoteness and poverty. The five-year intervention from 2005 through 2009 was carried out as a prospective study. The years of formation in 2005 and 2006 were used as a baseline cohort for comparisons with later annual cohorts. Non-professional and professional birth attendants at village level, rural health centers (HCs), and three hospitals were merged with an operational prehospital trauma system. Staff at all levels were trained in life support and emergency obstetrics. Findings The maternal mortality rate was reduced from a baseline level of 0.73% to 0.12% in the year 2009 (95% CI Diff, 0.27-0.98; P<.01). The main reduction was observed in deliveries at village level assisted by traditional birth attendants (TBAs). There was a significant reduction in perinatal mortality rate by year from a baseline level at 3.5% to 1.0% in the year 2009 (95% CI Diff, 0.02-0.03; P<.01). Adjusting maternal and perinatal mortality rates for risk factors, the changes by time cohort remained a significant explanatory variable in the regression model.

CONCLUSION

The results correspond to experiences from modern prehospital trauma systems: Basic Life Support reduces maternal and perinatal death if provided early. Trained TBAs are effective if well-integrated in maternal health programs. Houy C , Ha SO , Steinholt M , Skjerve E , Husum H .

OOSTT: a Resource for Analyzing the Organizational Structures of Trauma Centers and Trauma Systems

Organizational structures of healthcare organizations has increasingly become a focus of medical research. In the CAFÉ project we aim to provide a web-service enabling ontology-driven comparison of the organizational characteristics of trauma centers and trauma systems. Trauma remains one of the biggest challenges to healthcare systems worldwide. Research has demonstrated that coordinated efforts like trauma systems and trauma centers are key components of addressing this challenge. Evaluation and comparison of these organizations is essential. However, this research challenge is frequently compounded by the lack of a shared terminology and the lack of effective information technology solutions for assessing and comparing these organizations. In this paper we present the Ontology of Organizational Structures of Trauma systems and Trauma centers (OOSTT) that provides the ontological foundation to CAFÉ's web-based questionnaire infrastructure. We present the usage of the ontology in relation to the questionnaire and provide the methods that were used to create the ontology.

Dispatch of Helicopter Emergency Medical Services Via Advanced Automatic Collision Notification

BACKGROUND

Advanced automatic collision notification (AACN) is a system for predicting occupant injury from collision information. If the helicopter emergency medical services (HEMS) physician can be alerted by AACN, it may be possible to reduce the time to patient contact.

OBJECTIVE

The purpose of this study was to validate the feasibility of early HEMS dispatch via AACN.

METHODS

A full-scale validation study was conducted. A car equipped with AACN was made to collide with a wall. Immediately after the collision, the HEMS was alerted directly by the operation center, which received the information from AACN. Elapsed times were recorded and compared with those inferred from the normal, real-world HEMS emergency request process.

RESULTS

AACN information was sent to the operation center only 7 s after the collision; the HEMS was dispatched after 3 min. The helicopter landed at the temporary helipad 18 min later. Finally, medical intervention was started 21 min after the collision. Without AACN, it was estimated that the HEMS would be requested 14 min after the collision by fire department personnel. The start of treatment was estimated to be at 32 min, which was 11 min later than that associated with the use of AACN.

CONCLUSIONS

The dispatch of the HEMS using the AACN can shorten the start time of treatment for patients in motor vehicle collisions. This study demonstrated that it is feasible to automatically alert and activate the HEMS via AACN.

The contribution of the Israeli trauma system to the survival of road traffic casualties

BACKGROUND

According to the World Health Organization, over one million people die annually from traffic crashes, in which over half are pedestrians, bicycle riders and two-wheel motor vehicles. In Israel, during the last decade, mortality from traffic crashes has decreased from 636 in 1998 to 288 in 2011. Professionals attribute the decrease in mortality to enforcement, improved infrastructure and roads and behavioral changes among road users, while no credit is given to the trauma system. Trauma systems which care for severe and critical casualties improve the injury outcomes and reduce mortality among road casualties.

GOALS

1) To evaluate the contribution of the Israeli Health System, especially the trauma system, on the reduction in mortality among traffic casualties. 2) To evaluate the chance of survival among hospitalized traffic casualties, according to age, gender, injury severity and type of road user.

METHODS

A retrospective study based on the National Trauma Registry, 1998-2011, including hospitalization data from eight hospitals.

OUTCOMES

During the study period, the Trauma Registry included 262,947 hospitalized trauma patients, of which 25.3% were due to a road accident. During the study period, a 25% reduction in traffic related mortality was reported, from 3.6% in 1998 to 2.7% in 2011. Among severe and critical (ISS 16+) casualties the reduction in mortality rates was even more significant, 41%; from 18.6% in 1998 to 11.0% in 2011. Among severe and critical pedestrian injuries, a 44% decrease was reported (from 29.1% in 1998 to 16.2% in 2011) and a 65% reduction among bicycle injuries. During the study period, the risk of mortality decreased by over 50% from 1998 to 2011 (OR 0.44 95% 0.33-0.59. In addition, a simulation was conducted to determine the impact of the trauma system on mortality of hospitalized road casualties. Presuming that the mortality rate remained constant at 18.6% and without any improvement in the trauma system, in 2011 there would have been 182 in-hospital deaths compared to the actual 108 traffic related deaths. A 41% difference was noted between the actual number of deaths and the expected number.

CONCLUSIONS

This study clearly shows that without any improvement in the health system, specifically the trauma system, the number of traffic deaths would be considerably greater. Although the health system has a significant contribution on reducing mortality, it does not receive the appropriate acknowledgment or resources for its proportion in the fight against traffic accidents.

Norwegian trauma care: a national cross-sectional survey of all hospitals involved in the management of major trauma patients

BACKGROUND

Approximately 10% of the Norwegian population is injured every year, with injuries ranging from minor injuries treated by general practitioners to major and complex injuries requiring specialist in-hospital care. There is a lack of knowledge concerning the caseload of potentially severely injured patients in Norwegian hospitals. Aim of the study was to describe the current status of the Norwegian trauma system by identifying the number and the distribution of contributing hospitals and the caseload of potentially severely injured trauma patients within these hospitals.

METHODS

A cross-sectional survey with a structured questionnaire was sent in the summer of 2012 to all Norwegian hospitals that receive trauma patients. These were defined by number of trauma team activations in the included hospitals. A literature review was performed to assess over time the development of hospitals receiving trauma patients.

RESULTS

Forty-one hospitals responded and were included in the study. In 2011, four trauma centres and 37 acute care hospitals received a total of 6,570 trauma patients. Trauma centres received 2,175 (33%) patients and other hospitals received 4,395 (67%) patients. There were significant regional differences between health care regions in the distribution of trauma patients between trauma centres and acute care hospitals. More than half (52.5%) of the hospitals received fewer than 100 patients annually. The national rate of hospital admission via trauma teams was 13 per 10,000 inhabitants. There was a 37% (from 65 to 41) reduction in the number of hospitals receiving trauma patients between 1988 and 2011.

CONCLUSIONS

In 2011, hospital acute trauma care in Norway was delivered by four trauma centres and 37 acute care hospitals. Many hospitals still receive a small number of potentially severely injured patients and only a few hospitals have an electronic trauma registry. Future development of the Norwegian trauma system needs to address the challenge posed by a scattered population and long geographical distances. The implementation of a trauma system, carefully balanced between centres with adequate caseloads against time from injury to hospital care, is needed and has been shown to have a beneficial effect in countries with comparable challenges.

A plea for Croatian trauma system

This paper provides an insight into Croatian health system with special focus on trauma care. The current situation is explained from a domestic point of view, but an independent review by foreign observers is also included. Fragmented approach to the treatment of injured patients in Croatia should be replaced by networking of health care componenets into a unique chain of help. The concept and five methodological steps in the development of a succesfull trauma system are presented. A good start is definitely a reorganization of existing knowledge on the basis of internationally licesed courses and the adoption of trauma registry as a standard for future discussion. Individual components of the trauma system can not be separately "optimized" so clinical and financial decisions should be planned exclusively on the integral level.

Evaluating trauma center process performance in an integrated trauma system with registry data

BACKGROUND

The evaluation of trauma center performance implies the use of indicators that evaluate clinical processes. Despite the availability of routinely collected clinical data in most trauma systems, quality improvement efforts are often limited to hospital-based audit of adverse patient outcomes.

OBJECTIVE

To identify and evaluate a series of process performance indicators (PPI) that can be calculated using routinely collected trauma registry data.

MATERIALS AND METHODS

PPI were identified using a review of published literature, trauma system documentation, and expert consensus. Data from the 59 trauma centers of the Quebec trauma system (1999, 2006; N = 99,444) were used to calculate estimates of conformity to each PPI for each trauma center. Outliers were identified by comparing each center to the global mean. PPI were evaluated in terms of discrimination (between-center variance), construct validity (correlation with designation level and patient volume), and forecasting (correlation over time).

RESULTS

Fifteen PPI were retained. Global proportions of conformity ranged between 6% for reduction of a major dislocation within 1 h and 97% for therapeutic laparotomy. Between-center variance was statistically significant for 13 PPI. Five PPI were significantly associated with designation level, 7 were associated with volume, and 11 were correlated over time.

CONCLUSION

In our trauma system, results suggest that a series of 15 PPI supported by literature review or expert opinion can be calculated using routinely collected trauma registry data. We have provided evidence of their discrimination, construct validity, and forecasting properties. The between-center variance observed in this study highlights the importance of evaluating process performance in integrated trauma systems.

Evaluating trauma center structural performance: The experience of a Canadian provincial trauma system

BACKGROUND

Indicators of structure, process, and outcome are required to evaluate the performance of trauma centers to improve the quality and efficiency of care. While periodic external accreditation visits are part of most trauma systems, a quantitative indicator of structural performance has yet to be proposed. The objective of this study was to develop and validate a trauma center structural performance indicator using accreditation report data.

MATERIALS AND METHODS

Analyses were based on accreditation reports completed during on-site visits in the Quebec trauma system (1994-2005). Qualitative report data was retrospectively transposed onto an evaluation grid and the weighted average of grid items was used to quantify performance. The indicator of structural performance was evaluated in terms of test-retest reliability (kappa statistic), discrimination between centers (coefficient of variation), content validity (correlation with accreditation decision, designation level, and patient volume) and forecasting (correlation between visits performed in 1994-1999 and 1998-2005).

RESULTS

Kappa statistics were >0.8 for 66 of the 73 (90%) grid items. Mean structural performance score over 59 trauma centers was 47.4 (95% CI: 43.6-51.1). Two centers were flagged as outliers and the coefficient of variation was 31.2% (95% CI: 25.5% to 37.6%), showing good discrimination. Correlation coefficients of associations with accreditation decision, designation level, and volume were all statistically significant (r = 0.61, -0.40, and 0.24, respectively). No correlation was observed over time (r = 0.03).

CONCLUSION

This study demonstrates the feasibility of quantifying trauma center structural performance using accreditation reports. The proposed performance indicator shows good test-retest reliability, between-center discrimination, and construct validity. The observed variability in structural performance across centers and over-time underlines the importance of evaluating structural performance in trauma systems at regular intervals to drive quality improvement efforts.

Feasibility and early outcomes of intensivist-led critical care after major trauma in the Korean ICU

PURPOSE

Substantial evidence supports the benefits of an intensivist model of critical care delivery. However, currently, this mode of critical care delivery has not been widely adopted in Korea. We hypothesized that intensivist-led critical care is feasible and would improve ICU mortality after major trauma.

MATERIALS AND METHODS

A trauma registry from May 2009 to April 2011 was reviewed retrospectively. We evaluated the relationship between modes of ICU care (open vs. intensivist) and in-hospital mortality following severe injury [Injury Severity Score (ISS)>15]. An intensivist-model was defined as ICU care delivered by a board-certified physician who had no other clinical responsibilities outside the ICU and who is primarily available to the critically ill or injured patients. ISS and Revised Trauma Score were used as measure of injury severity. The Trauma and Injury Severity Score methodology was used to calculate each individual patient's probability of survival.

RESULTS

Of the 251 patients, 57 patients were treated by an intensivist [intensivist group (IG)] while 194 patients were not [non-intensivist group (NIG)]. The ISS of IG was significantly higher than that for NIG (26.5 vs. 22.3, p=0.023). The hospital mortality rate for IG was significantly lower than that for NIG (15.8% and 27.8%, p<0.001).

CONCLUSION

The intensivist model of critical care is feasible, and there is room for improvement in the care of major trauma patients. Although trauma systems take time to mature, future studies are needed to evaluate the best model of critical care delivery for severely injured patients in Korea.

Trends in survival and early functional outcomes from hospitalized severe adult traumatic brain injuries, pennsylvania, 1998 to 2007

OBJECTIVE

: To determine trends for in-hospital survival and functional outcomes at acute care hospital discharge for patients with severe adult traumatic brain injury (SATBI) in Pennsylvania, during 1998 to 2007.

METHODS

: Secondary analysis of the Pennsylvania trauma outcome study database.

MAIN OUTCOME MEASURES

: Survival and functional status scores of 5 domains (feeding, locomotion, expression, transfer mobility, and social interaction) fitted into logistic regression models adjusted for age, sex, race, comorbidities, injury mechanism, extracranial injuries, severity scores, hospital stay, trauma center, and hospital level. Sensitivity analyses for functional outcomes were performed.

RESULTS

: There were 26 234 SATBI patients. Annual numbers of SATBI increased from 1757 to 3808 during 1998 to 2007. Falls accounted for 47.7% of all SATBI. Survival increased significantly from 72.5% to 82.7% (odds ratio [OR] = 1.10, 95% CI: 1.08-1.11, P < .001). In sensitivity analyses, trends of complete independence in functional outcomes increased significantly for expression (OR = 1.01, 95% CI: 1.00-1.02, P = .011) and social interaction (OR = 1.01, 95% CI: 1.00-1.03, P = .002). There were no significant variations over time for feeding, locomotion, and transfer mobility.

CONCLUSIONS

: Trends for SATBI served by Pennsylvania's established trauma system showed increases in rates but substantial reductions in mortality and significant improvements in functional outcomes at discharge for expression and social interaction.

Patients Referred to a Norwegian Trauma Centre: effect of transfer distance on injury patterns, use of resources and outcomes

BACKGROUND

Triage and interhospital transfer are central to trauma systems. Few studies have addressed transferred trauma patients. This study investigated transfers of variable distances to OUH (Oslo University Hospital, Ullevål), one of the largest trauma centres in Europe.

METHODS

Patients included in the OUH trauma registry from 2001 to 2008 were included in the study. Demographic, injury, management and outcome data were abstracted. Patients were grouped according to transfer distance: ≤20 km, 21-100 km and > 100 km.

RESULTS

Of the 7.353 included patients, 5.803 were admitted directly, and 1.550 were transferred. The number of transfers per year increased, and there was no reduction in injury severity during the study period. Seventy-six per cent of the transferred patients were severely injured. With greater transfer distances, injury severity increased, and there were larger proportions of traffic injuries, polytrauma and hypotensive patients. With shorter distances, patients were older, and head injuries and injuries after falls were more common. The shorter transfers less often activated the trauma team: ≤20 km -34%; 21-100 km -51%; > 100 km -61%, compared to 92% of all directly admitted patients. The mortality for all transferred patients was 11%, but was unequally distributed according to transfer distance.

CONCLUSION

This study shows heterogeneous characteristics and high injury severity among interhospital transfers. The rate of trauma team assessment was low and should be further examined. The mortality differences should be interpreted with caution as patients were in different phases of management. The descriptive characteristics outlined may be employed in the development of triage protocols and transfer guidelines.

Rural Hospital Transfer Patterns before and after Implementation of a Statewide Trauma System

OBJECTIVE

To evaluate trauma transfer practices in rural Oregon before and after implementation of a statewide trauma system.

METHODS

A pre- vs post-system implementation (historical control) analysis of trauma transfer practices was performed using a sample of rural ED trauma patients from 4 Level-3 and 5 Level-4 trauma hospitals. Medical records of patients with specific index injury diagnoses in 4 anatomic regions (head, chest, liver/ spleen, and femur/open-tibia) were reviewed for a 3-year period before statewide trauma system implementation and 3 years after hospital trauma designation.

RESULTS

Of 1,057 patients entered into the database, 532 were evaluated during the pre-system period and 525 were evaluated during the post-system period. Overall, 47% had head injuries, 34% had chest injuries, 23% had femur/open-tibia injuries, and 12% had spleen/liver injuries. There were 142 (13%) patients with an injury in >1 index area. After trauma system implementation, there was a significant increase in the proportion of ED trauma patients transferred from Level-4 trauma hospitals (32% vs 68%, p < 0.001), with a corresponding decrease in the number of hospital admissions to these facilities (63% to 29%, p < 0.001). Significant increases in the proportion transferred from Level-4 trauma hospital EDs were noted for all index injury categories (p < 0.001). Trauma patients presenting to Level-4 EDs were significantly more likely to be transferred to Level-2 facilities (66% vs 82%, p = 0.030), while patients at Level-3 facilities were significantly more likely to be transferred to Level-1 centers (2% vs 14%, p = 0.002) following trauma system implementation. Multiple logistic regression modeling indicated that implementation of the statewide trauma system was an independent predictor of rural trauma patient transfer from Level-4 hospitals, while transfers from Level-3 facilities were dependent on type of injury.

CONCLUSION

Implementation of the Oregon statewide trauma system was associated with a redistribution of rural trauma patients to trauma hospitals with greater therapeutic resources.
