Differences in trauma team activation criteria among Norwegian hospitals

The Norwegian national trauma registry: development process and essential data insights

BACKGROUND

Understanding trauma epidemiology, patient demographics, injury characteristics, and outcomes is essential for optimising trauma systems. The Norwegian Trauma Registry (NTR) monitors and improves the Norwegian Trauma System, setting care standards and overseeing system development. The registry was officially recognised as a national register in 2013. This study outlines the establishment of the population-based national registry and provides an overview of selected data.

METHODS

Norway's trauma system includes trauma centres, acute care hospitals, and prehospital services. The registry collects injury details, clinical outcomes, and patient experiences. Local NTR databases that are linked to a central database are maintained at each hospital, and only certified data registrars can enter and validate data. This enables data linkages across hospitals. The NTR includes potentially severely injured patients but also includes undertriaged patients (defined as severely injured patients who are not met by a trauma team activation upon hospital arrival). Descriptive statistics were used to analyse data from trauma patients registered between 2015 and 2023. Patient-Reported Outcome Measures (PROMs) from 2022 were also assessed.

RESULTS

From 2015 to 2023, 78 275 trauma patients were recorded, with annual patient inclusion rising from 7586 in 2015 to 9759 in 2023. All 38 Norwegian hospitals contributed data in 2023. Median age was 41 years (IQR: 21-62), and 66.5% were men. The highest injury rate was among those aged 15-24 years. Penetrating injuries accounted for 4.6% of cases. Severely injured patients with New Injury Severity Score (NISS) ≥ 16 totalled 16 678 (21.3%), while 10 509 (13.4%) had an Injury Severity Score (ISS) ≥ 16. Polytrauma was identified in 3783 (4.9%) of patients using the Newcastle definition and in 2508 (3.2%) patients using the Berlin definition. In 2023, a trauma team was activated for 8731(89.4%) patients recorded in the registry. PROMs data from 2022 showed that 47.2% (1018/2157) of the patients reported anxiety or depression 12 months post-injury. Among those without physical injuries, 8.0% (11/138) were out of work or education. Of the severely injured patients (NISS ≥ 16) who were employed or in education prior to the injury, 26.4% (83/314) had not returned to work or education after 12 months.

CONCLUSIONS

The Norwegian Trauma Registry has been successfully implemented in all trauma hospitals in Norway, enabling comprehensive data collection to support trauma care improvements and research.

Adherence to national trauma triage criteria in Norway: a cross-sectional study

BACKGROUND

Norwegian hospitals employed individual trauma triage criteria until 2015 when nationwide criteria were implemented. There is a lack of empirical evidence regarding adherence to Norwegian national criteria for activation of the trauma team (NTrC) and the decision-making processes regarding trauma team activation (TTA) within Norwegian trauma hospitals. The objectives of this study were to investigate institutional adherence to the NTrC and to investigate similarities and differences in the decision-making process leading to TTA in Norwegian trauma hospitals.

METHODS

A digital semi-structured questionnaire regarding adherence to criteria, TTA decision-making and criteria documentation was distributed to all Norwegian trauma hospitals (n = 38) in the spring of 2022. Contact details of trauma coordinators and registrars were provided by the Norwegian Trauma Registry secretariat. Follow-up telephone interviews were conducted at the investigator's discretion in cases of non-respondents or need to clarify answers.

RESULTS

Thirty-eight trauma hospitals were invited to answer the survey, where 35 hospitals responded (92%), making 35 the denominator of the results. Thirty-four (97.1%) hospitals stated that they followed NTrC. Thirty-three (94.3%) of the responding hospitals provided documentation of their criteria in use, of which twenty-eight (80%) of responding hospitals adhered to the NTrC. Three (8.6%) hospitals employed a tiered TTA approach with different sized teams. In addition four hospitals (11.4%) used specialized teams to meet the needs of defined patient groups (e.g. geriatric patients, traumatic brain injury). Twenty-one (60%) of the responding hospitals had written guidelines on who could perform TTA and in 18 hospitals (51.4%) TTA could be performed by pre-hospital personnel. Twenty-three (65.7%) of the hospitals documented which criteria that were used for TTA.

CONCLUSION

There is good adherence to the national criteria for activation of the trauma team among Norwegian trauma hospitals after implementation of national guidelines. Individual hospitals argue the use of certain local criteria and trauma team activation decision-making processes to increase their precision in specific patient populations and demographics. Further steps should be done to reduce the variation in TTA decision-making processes among hospitals and improve documentation quality.

Optimizing Trauma Activation Criteria for a Rural Trauma Center

BACKGROUND

There is a need for activation criteria that reflect the different factors affecting rural trauma patients.

OBJECTIVE

To develop effective activation criteria for a rural trauma center among adults, incorporating variables specific to the geography, mechanisms of injury, and population served.

METHODS

This is a single-center, retrospective cohort study conducted from (23 years) January 1, 2000, to July 31, 2023. The data collected patient demographics, injury details, morbidity, and preexisting comorbidity. This research included all adult (≥15 years) true Level I trauma activations defined as an injury severity score > 25 and met the need for trauma intervention criteria. The patients were grouped into adult and elderly categories. The analysis utilized a logistic regression model with the outcome of a true Level I trauma activation.

RESULTS

A total of 19,480 patients were included in the sample; 2,858 (14.6%) met the Level I activation criteria. Elderly Level I activation included assault, pedestrian struck, multiple pelvic fractures, traumatic pneumo/hemothorax, mediastinal fracture, sternum fracture, and flail rib fracture.

CONCLUSION

Using the findings of the logistic regression model, this center has made more robust activation guidelines adapted to its rural population.

Evaluating the impact of pre-hospital trauma team activation criteria

BACKGROUND

Little evidence exists studying the benefits of pre-hospital trauma team activation. Our study measured the impact of pre-hospital trauma team activation on 24-h survival. Our secondary objectives assessed the effects of pre-hospital trauma team activation on time to emergency procedure, computed tomography, blood transfusion, and critical administration threshold, as well as emergency department length of stay.

METHODS

We conducted a 40-month health records review on all trauma team activations at The Ottawa Hospital, a Level 1 Trauma Center. Outcomes were compared between pre-hospital and in-hospital trauma team activations. We used logistic and linear regression models to assess outcomes, while controlling for injury severity score, age, systolic blood pressure, and anti-coagulation use. A P value < 0.05 was considered statistically significant. A sensitivity analysis was also used to validate the primary outcome results.

RESULTS

Of the 1013 trauma team activations occurring during the study period, 762 patients were included. The mean age (41.3 vs. 43.8) and percentage of males (79.4% vs. 77.5%) for pre-hospital activations were similar to their counterparts. Pre-hospital activations did not have a statistically significant effect on 24-h mortality (14.4% vs. 4.5%; P = 0.30). However, pre-hospital activations did demonstrate a statistically significant reduction in time (minutes) to emergency procedure (18.0 vs. 27.0; P < 0.001), computed tomography (37.0 vs 42.0; P = 0.009), and blood transfusion (14.0 vs. 28.0; P < 0.001), as well as emergency department length of stay (101.0 vs. 171.0; P < 0.001).

CONCLUSION

When controlling for key covariates, pre-hospital trauma team activation did not have a significant effect on 24-h mortality, but did result in a significant reduction in time to emergency procedure, computed tomography, and blood transfusion, as well as emergency department length of stay. Our study demonstrates that pre-hospital trauma team activation can expedite patient intervention and disposition.

The potential of point-of-care diagnostics to optimise prehospital trauma triage: a systematic review of literature

PURPOSE

In the prehospital care of potentially seriously injured patients resource allocation adapted to injury severity (triage) is a challenging. Insufficiently specified triage algorithms lead to the unnecessary activation of a trauma team (over-triage), resulting in ineffective consumption of economic and human resources. A prehospital trauma triage algorithm must reliably identify a patient bleeding or suffering from significant brain injuries. By supplementing the prehospital triage algorithm with in-hospital established point-of-care (POC) tools the sensitivity of the prehospital triage is potentially increased. Possible POC tools are lactate measurement and sonography of the thorax, the abdomen and the vena cava, the sonographic intracranial pressure measurement and the capnometry in the spontaneously breathing patient. The aim of this review was to assess the potential and to determine diagnostic cut-off values of selected instrument-based POC tools and the integration of these findings into a modified ABCDE based triage algorithm.

METHODS

A systemic search on MEDLINE via PubMed, LIVIVO and Embase was performed for patients in an acute setting on the topic of preclinical use of the selected POC tools to identify critical cranial and peripheral bleeding and the recognition of cerebral trauma sequelae. For the determination of the final cut-off values the selected papers were assessed with the Newcastle-Ottawa scale for determining the risk of bias and according to various quality criteria to subsequently be classified as suitable or unsuitable. PROSPERO Registration: CRD 42022339193.

RESULTS

267 papers were identified as potentially relevant and processed in full text form. 61 papers were selected for the final evaluation, of which 13 papers were decisive for determining the cut-off values. Findings illustrate that a preclinical use of point-of-care diagnostic is possible. These adjuncts can provide additional information about the expected long-term clinical course of patients. Clinical outcomes like mortality, need of emergency surgery, intensive care unit stay etc. were taken into account and a hypothetic cut-off value for trauma team activation could be determined for each adjunct. The cut-off values are as follows: end-expiratory CO2: < 30 mm/hg; sonography thorax + abdomen: abnormality detected; lactate measurement: > 2 mmol/L; optic nerve diameter in sonography: > 4.7 mm.

DISCUSSION

A preliminary version of a modified triage algorithm with hypothetic cut-off values for a trauma team activation was created. However, further studies should be conducted to optimize the final cut-off values in the future. Furthermore, studies need to evaluate the practical application of the modified algorithm in terms of feasibility (e.g. duration of application, technique, etc.) and the effects of the new algorithm on over-triage. Limiting factors are the restriction with the search and the heterogeneity between the studies (e.g. varying measurement devices, techniques etc.).

Increased risk of fatal paediatric injuries in rural Northern Norway

Background

Finnmark, Northern Norway, had a mortality rate for paediatric injury in 1998‐2007 that was more than twice the national average. We investigated whether this rate had decreased in 2008‐2015 after improvements in emergency care. We also compared the mortality rate to rates of non‐fatal injury and trauma team activation both regionally and in Norway.

Methods

The study was based on 4 national registries. Mortality and injury rates were calculated per 100 000 persons per year. The study population was divided into age groups; 0‐5, 6‐10, 11‐15 and 16‐17 years.

Results

Between 1998‐2007 and 2008‐2015 there was an overall decrease in paediatric mortality rate due to external causes in Norway in total from 7.1 to 4.0. Despite this, in 2008‐2015, the mortality rate remained 2.5 times higher in Finnmark than in Norway (9.7, RR = 2.5 CI 1.4‐4.3, P = 0.001), similar to findings for 1998‐2007. Finnmark had half the rate of non‐fatal injuries in 1999‐2007 (5052, RR = 0.6, 95% CI 0.6‐0.7, P < 0.001) and in 2008‐2015 (3893, RR = 0.5, 95% CI 0.5‐0.6, P < 0.001) as in Norway. The rate of trauma team activation was similar in Finnmark and Norway.

Conclusions

The risk of injury‐related death remained significantly higher, while the overall risk of non‐fatal injury was significantly reduced for children in rural Northern Norway. Thus, injuries in this rural area seem to be less frequent but more severe. There is a need for detailed examination of each death to determine possible preventive measures.

Neurologic Emergencies Presenting as Trauma Activations to an Urban Level I Trauma Center

BACKGROUND

It is speculated that there is overlap between neurologic emergencies and trauma, yet to date there has not been a study looking at the prevalence of neurologic emergencies amongst trauma activations.

OBJECTIVES

We sought to determine the prevalence of neurologic emergencies in patients presenting to a level I trauma center as trauma team activations (TTAs). We explored a subset of acute ischemic stroke patients to determine delays in management.

METHODS

This was a retrospective review of trauma registry data capturing all TTAs at a level I trauma and stroke center from 2011 to 2016. Neurologic emergencies were defined as ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, or status epilepticus. Among patients diagnosed with acute ischemic strokes, we compared stroke metrics with hospital stroke data during the same period.

RESULTS

There were 18,859 trauma activations during the study period, of which 117 (0.6%) had a neurologic emergency. There were 52 patients with ischemic stroke (45%), 39 with intracerebral hemorrhage (34%), 15 with subarachnoid hemorrhage (13%), and 10 with status epilepticus (9%). Among the 52 patients with ischemic stroke, 20 (38%) received intravenous thrombolysis. The median time to computed tomography scan was 23 min and the median time to thrombolysis (tissue plasminogen activator) was 60 min. When compared with non-TTA patients during the same time period, both median time to computed tomography scan and time to tissue plasminogen activator were similar (p = 0.16 and p = 0.6, respectively).

CONCLUSIONS

Neurologic emergencies, though relatively uncommon, do exist among TTAs. Despite the TTA, eligible patients met the benchmarks for acute stroke care delivery.

Comparison of Fatal Injuries Resulting from Tractor and High Speed Motorcycle Accidents in Turkey: A Multicenter Study

Aim

Injuries are among the main causes of mortality and morbidity all over the world, and effective initial triage of these patients can determine the thin line between death and life. Tractor accidents and related injuries are significant problems particularly in rural areas. However, major trauma classification systems do not include tractor accidents as a criterion for trauma team activation or transportation of the patients to a trauma center. This study evaluated the general characteristics and outcomes of tractor accidents in comparison to motorcycle accidents, which are considered as a comparison criterion for major trauma.

Materials and Methods

This is a multicenter study conducted in 6 emergency departments in 4 cities over a six month period. All cases over 18 years of age who were admitted to emergency service due to tractor or motorcycle accidents and meet the criteria were included in the study. The general characteristics and outcomes of both trauma types were compared to determine whether tractor accident should be considered as major traumas.

Results

Eighty-eight patients had a tractor accident, and 339 patients had a motorcycle accident. The tractor accident victims were significantly younger (p<0.001), and the proportion of females was higher in this group (p=0.001). Glasgow coma score (p=0.062), revised trauma score (p=0.201), duration from incident to admission (p=0.481), and route of admission (p=0.810) were similar between both accident types. The rates of thoracic traumas (42% versus 23%, p<0.001) and spinal injuries (17% versus 5.9%, p=0.002) were significantly higher in tractor accidents. The hospitalization rates of the patients were significantly higher in tractor accidents (p=0.008).

Conclusion

The findings of this study support the hypothesis that tractor accidents should be included in the criteria of ATLS major trauma classification system and trauma team activation procedures.

Population-based analysis of the impact of trauma on longer-term functional outcomes

BACKGROUND

Functional outcome measures are important as most patients survive trauma. The aim of this study was to describe the long-term impact of trauma within a healthcare region from a social perspective.

METHODS

People active in work or education and admitted to hospitals in Central Norway in the interval 1 June 2007 to 31 May 2010 after sustaining trauma were included in the study. Clinical data were linked to Norwegian national registers of cause of death, sickness and disability benefits, employment and education. Primary outcome measures were receipt of medical benefits and time to return to preinjury work level. Secondary outcome measures were mortality within 30 days or during follow-up.

RESULTS

Some 1191 patients were included in the study, of whom 193 (16·2 per cent) were severely injured (Injury Severity Score greater than 15). Five years after injury, the prevalence of medical benefits was 15·6 per cent among workers with minor injuries, 22·3 per cent in those with moderate injuries and 40·5 per cent among workers with severe injuries. The median time after injury until return to work was 1, 4 and 11 months for patients with minor, moderate and severe injuries respectively. Twelve patients died within 30 days and an additional 17 (1·4 per cent) during follow-up.

CONCLUSION

Patients experiencing minor or major trauma received high levels of medical benefits; however, most recovered within the first year and resumed preinjury work activity. Patients with severe trauma were more likely to receive medical benefits and have a delayed return to work. Registration number: NCT02602405 (http://www.clinicaltrials.gov).

Evaluating the ability of a trauma team activation tool to identify severe injury: a multicentre cohort study

Background

Sensitive decision making tools should assist prehospital personnel in the triage of injured patients, identifying those who require immediate lifesaving interventions and safely reducing unnecessary under- and overtriage. In 2014 a new trauma team activation (TTA) tool was implemented in Central Norway. The overall objective of this study was to evaluate the ability of the new TTA tool to identify severe injury.

Methods

This was a multi-center observational cohort study with retrospective data analysis. All patients received by trauma teams at seven hospitals in Central Norway between 01.01.2015 to 31.12.2015 were included. Severe injury was defined as Injury Severity Score (ISS) > 15. Overtriage was defined as the rate of patients with TTA and ISS < 15, whilst patients with TTA and ISS > 15 were defined as correctly triaged.

Results

A total of 1141 patients were identified, of which 998 were eligible for triage criteria analysis. Median age was 35 years (IQR 20–58) and the male proportion was 67%. Mechanism of injury was predominantly blunt trauma (96%) with transport related accidents (62%) followed by falls (22%) the most common. Overall, median injury severity score (ISS) was low and severely injured patients (ISS > 15) comprised 13% of the cohort. Utility of specific TTA criteria were: physiology 20%, anatomical injury 21%, mechanism of injury (MOI) 53% and special causes 6%. Overtriage among all patients was 87%, and for those with physiologic criteria 66%, anatomical injury 82%, mechanism of injury 97% and special causes criteria 92%, respectively.

Conclusions

Severe injury was infrequent and there was a substantial rate of overtriage. The ability of the TTA tool was relatively insensitive in identifying severe injury, but showed increased performance when utilizing physiologic and anatomical injury criteria. Many of the TTA mechanism of injury criteria might be considered for removal from the triage tool due to substantial rates of overtriage. This has relevance for the proposed development of national Norwegian TTA criteria.

Simple modification of trauma mechanism alarm criteria published for the TraumaNetwork DGU® may significantly improve overtriage - a cross sectional study

Background

No consensus exists in the literature on the use of uniform emergency room trauma team activation criteria (ERTTAC). Today excessive over- or undertriage rates continue to be a challenge for most trauma centres. Application of ERTTAC, published for use in the German TraumaNetwork DGU^®, at a Swiss trauma centre resulted in a high overtriage rate. The aim of the investigation was to analyse the ERTTAC in detail with the intention of possible improvement.

Methods

The investigation included consecutive adult (age > 15 years) trauma patients treated at the emergency department of a level II trauma centre from 01.01.2013–31.12.2015. All data were collected prospectively. To identify over- and undertriage, patients with an Injury Severity Score (ISS) > 15 were defined as requiring specific emergency room (ER) management. ANOVA, Student’s t-test and chi-square analysis were used for statistical analysis with mean values ± standard deviation.

Results

1378 adult injured (64% male) received ER trauma team treatment (mean age 48.3 ± 21.2 years; ISS 9.7 ± 9.6) during the observation period. Of those, 326 ER patients (23.7%) were diagnosed with an ISS > 15, which proved to be an overtriage of 76.3%. 80/406 trauma patients with an ISS > 15 were not referred to the ER, resulting in an actual undertriage rate of 19.7%, mainly because the criteria list was not observed. Effectively applying ERTTAC according to the protocol in all cases would have reduced undertriage to 2.0% (8/406). The most frequent trigger for trauma team activation was injury mechanism (65%). A simulation revealed that omitting the criterion ‘passenger of car or truck’ (n = 326) would have prevented overtriage in 257 cases, as such lowering overtriage rate to 62.4% and at the same time increasing undertriage by only 8 cases to 7.1%.

Conclusion

Application of ERTTAC as published for TraumaNetwork DGU^® resulted in a lower undertriage but higher overtriage rate than recommended by the American College of Surgeons. Omitting the criterion ‘passenger of car or truck’ markedly improved overtriage with only a minimal increase in undertriage.

Effect of team training on efficiency of trauma care in a Chinese hospital

Objective

Multidisciplinary trauma teams are the standard of care in the USA, but staffing differences and lack of advanced trauma life support training hinder replication of this system in Chinese hospitals. We investigated the effect of simulation team training on initial trauma care.

Methods

Over 15 months, we compared grade I trauma patients cared for by the trained team and those cared for using traditional practice on times from emergency room arrival to tests/procedures. Propensity-score analysis was performed to improve between-group comparisons.

Results

During the study, 144 grade I trauma patients were treated. Trained team patients showed shorter times from emergency room arrival to initiation of hemostasis (31.0 [13.5–58.5] vs. 113.5 [77–150.50] min), blood routine report (8 [5–10.25] vs. 13 [10–21] min), other blood tests (21 [14.75–25.75] vs. 31 [25–37] min), computed tomography scan (29.5 [20.25–65] vs. 58.5 [30.25–71.25] min) and tranexamic acid administration (31 [13–65] vs. 90 [65–200] min). Similar results were obtained for the propensity-score matched cohort.

Conclusion

Simulation team training could help reduce time to blood routine reports, scans and hemostasis. Assessment of available resources and development of targeted team training could improve care in resource-limited hospitals.

Trauma care in a combined rural and urban region: an observational study

BACKGROUND

The available information on trauma care in mixed rural-urban areas with scattered populations is limited. The aim of this study is to describe epidemiology, resource use, transfers and outcomes for trauma care within such an area, prior to implementation of a formal trauma system.

METHODS

A multicentre observational study including potential severely injured patients from June 2007 to May 2010. All patients received by trauma teams at seven acute care hospitals (ACH) and one major trauma centre (MTC) were included. Major trauma was defined as Injury Severity Score (ISS) > 15.

RESULTS

A total of 2323 patients were included. ACH received 1330 patients and delivered definite care to 85% of these. Only 329 (14%) patients were major trauma of which 134 (41%) were initially received at an ACH. Nine per cent of patients were transferred between hospitals. After inter-hospital transfers, 79% of all major trauma patients received definite care at the MTC. Helicopter emergency services admitted 52% of major trauma and performed 68% of inter-hospital transfers from ACH to MTC. Forty-eight patients (2%) died within 30 days.

CONCLUSION

In a region with a dispersed network of hospitals, geographical challenges, and low rate of major trauma cases, efforts should be made to identify patients with major trauma for treatment at a MTC as early as possible. This can be done by implementing triage and transfer guidelines, maintaining competence at ACHs for initial stabilization, and sustaining an organization for effective inter-facility transfers.

Evaluation of a trauma team activation protocol revision: a prospective cohort study

Background

Correct triage based on prehospital information contributes to a better outcome for potentially seriously injured patients. In 2011 we changed the trauma team activation (TTA) criteria in our center in order to improve the high over- and undertriage properties of the protocol. Five criteria that were unable to predict severe injury were removed. In the present study, we evaluated the protocol revision by comparing over- and undertriage in the former and present set of criteria.

Methods

All severely injured patients (Injury Severity Score (ISS) > 15) and all patients admitted with TTA in the period of 01.01.2013 – 31.12.2014 were included in the study. We defined overtriage as the fraction of patients with TTA when ISS ≤15 and undertriage as the fraction of patients without TTA when ISS > 15. We also evaluated triage with the occurrence of emergency procedures immediately after admission.

Results

324 patients were included, 164 patients had ISS>15, 287 were admitted with TTA. Over- and undertriage were 74 % and 28 % respectively. When we used emergency procedure as reference, the figures were 83 % and 15 % respectively. Undertriaged patients had significantly more neurosurgical injuries and were significantly more often transferred from an acute care hospital.

Discussion

Over- and undertriage are almost the same as before the criteria were revised, and higher thanrecommended levels.

Conclusions

Revision of the TTA criteria has not improved triage, and further measures are necessary to achieveacceptable levels.

Trauma team activation criteria in managing trauma patients at an emergency room in Thailand

BACKGROUND

Trauma team activation (TTA) criteria were first implemented in the Emergency Department (ED) of Songklanagarind Hospital in 2009 to treat severe trauma patients.

PURPOSE

To determine the efficacy of the TTA criteria on the acute trauma care process in the ED and the 28-day mortality rate.

METHODS

A 1-year prospective cohort study was conducted at the ED. Trauma patients who were 18 years old and over who met the TTA criteria were enrolled. Demographic data, physiologic parameters, ED length of stay (EDLOS), and the injury severity score (ISS) were recorded. Multiple logistic regression was used to determine the factors affecting 28-day mortality. Institutional review board approval was obtained from the Prince of Songkla University.

RESULTS

A total of 80 patients (74 male and 6 female) were eligible with a mean age of 34.3 years old. Shock, penetrating torso injury, and pulse rate >120 beats per minute were the three most common criteria for trauma team consultation. At the ED, 9 patients (11.3 %) were non-survivors, 30 patients (37.5 %) needed immediate operation, and 41 patients (51.2 %) were admitted. All of the arrest patients died (p < 0.0001). The median time of EDLOS was 85 min: 68 min in the non-survivor group and 120 min in the survivor group (p = 0.028). The median ISS was 21.0 (1-75): 25.0 in the non-survivor group and 17.0 in the survivor group. When compared with pilot data prior to TTA implementation, the median time of EDLOS improved from 184 to 85 min and the 28-day mortality rate decreased from 66.7 to 46.3 %. The high ISS was a predictor of death.

CONCLUSION

The trauma team activation criteria improved acute trauma care in the ED which was demonstrated by the decreased EDLOS and mortality rate. A high ISS is the sole parameter predicting mortality.

Trauma team activation varies across Dutch emergency departments: a national survey

Background

Tiered trauma team response may contribute to efficient in-hospital trauma triage by reducing the amount of resources required and by improving health outcomes. This study evaluates current practice of trauma team activation (TTA) in Dutch emergency departments (EDs).

Methods

A survey was conducted among managers of all 102 EDs in the Netherlands, using a semi-structured online questionnaire.

Results

Seventy-two questionnaires were analysed. Most EDs use a one-team system (68 %). EDs with a tiered-response receive more multi trauma patients (p < 0.01) and have more trauma team alerts per year (p < 0.05) than one-team EDs. The number of trauma team members varies from three to 16 professionals. The ED nurse usually receives the pre-notification (97 %), whereas the decision to activate a team is made by an ED nurse (46 %), ED physician (30 %), by multiple professionals (20 %) or other (4 %). Information in the pre-notification mostly used for trauma team activation are Airway-Breathing-Circulation (87 %), Glasgow Coma Score (90 %), and Revised Trauma Score (85 %) or Paediatric Trauma Score (86 %). However, this information is only available for 75 % of the patients or less. Only 56 % of the respondents were satisfied with their current in-hospital trauma triage system.

Conclusions

Trauma team activation varies across Dutch EDs and there is room for improvement in the trauma triage system used, size of the teams and the professionals involved. More direct communication and more uniform criteria could be used to efficiently and safely activate a specific trauma team. Therefore, the implementation of a revised national consensus guideline is recommended.

Restructuring an evolving Irish trauma system: What can we learn from Europe and Australia?

AIM

Major trauma is a leading cause of mortality and disability. Internationally, major trauma centres and comprehensive trauma networks are associated with improved outcomes. This study aimed to examine selected international trauma systems in Europe and Australia to identify common themes that may aid reconfiguration of the Irish trauma service.

METHODS

An electronic search strategy was utilised using Medline, and a search of the grey literature using Google and Google Scholar. Search terms included "trauma systems", "trauma care", "major trauma centre" and "trauma network". Relevant articles were reviewed and data summarised in a narrative format.

RESULTS

Republic of Ireland currently lacks designated major trauma centres and surrounding trauma networks. Lessons from international models and data from the on-going national trauma audit may guide reconfiguration. Well-functioning trauma systems internationally bear striking similarities, and involve a hub and spoke model. This model has a central major trauma centre, surrounded by a co-ordinated trauma network with trauma units. Concentration of major trauma into high volume centres is key, but these centres must be adequately resourced to deliver a high quality service. Investment in and co-ordination of prehospital care is essential to overcome geographical impediments to centralising trauma care. Funding of rehabilitation infrastructure and resources is also an integral part of a well-functioning trauma system. Trauma outcome data is key to informing trauma system design, with dissemination of this data and public engagement critical for change.

CONCLUSION

International models of trauma care provide valuable lessons for countries currently in process of reconfiguring trauma services.

Nine out of ten trauma calls to a Norwegian hospital are avoidable: a retrospective analysis

Background

Our aim was to estimate the degree of overtriage (Injury Severity Score [ISS] ≤ 15) of trauma call patients in Nordland Hospital Bodø, Norway. We also determined the transportation time from injury to hospital admission.

Methods

We used data from our Acute Medical Information System, ambulance records and patient charts relating to ISS and estimation of response and transport times. Data were collected for all trauma call patients in the period from the establishment of the trauma call system in June 2008 until the 31st of December 2010.

Results

We identified 421 out of 458 possible trauma call patients with sufficient clinical information available for ISS scoring. Of these 385 had an ISS ≤15. Overtriage was 91.5% (95% CI: 88.8%–94.2%). Median time from injury to the arrival of transport, and from injury to arrival in hospital, was 36 minutes and 1 hour 27 minutes, respectively.

Conclusions

To our knowledge 91.5% is the highest overtriage ever published. There is a need for narrowing the trauma call criteria. This could be achieved by implementing clinical observations during the long transportation time.

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 validation study of 5 triage systems using data from the 2005 Graniteville, South Carolina, chlorine spill

INTRODUCTION

Lack of outcomes-based research results in uncertainty about the effectiveness of any of the current triage systems in determining priority of care during actual chemical disasters. The purpose of this study was to determine whether the level of injury severity extrapolated from 5 triage systems correlated with actual injury severity outcomes of victims exposed to a chlorine disaster.

METHODS

Using secondary data analysis, data for 631 victims were merged, de-identified, and analyzed. Using logic models from the triage systems, the actual injury severity was compared with the extrapolated injury severity classifications.

RESULTS

Analysis showed weak to modest correlations between the extrapolated injury severity triage outcome classifications and the actual injury severity outcomes (Spearman correlation range 0.38 to 0.71, P < .0001). There was slight to fair agreement between the extrapolated injury severity triage outcome classifications and the actual injury severity outcomes (weighted κ = - 0.23 to 0.42).

DISCUSSION

The extrapolated injury severity triage outcome categories from the 5 triage systems did not agree with the actual injury severity categories. Oxygen saturation measured by pulse oximetry provides early indications and is very predictive of outcome severity in incidents involving irritant chemical exposures such as chlorine, and should be a part of a mass casualty protocol for any irritant chemical incident. Additional research is needed to identify the most sensitive clinical measures for triaging victims of toxic inhalation disasters.

Does young age merit increased emergency department trauma team response?

Introduction:

To determine if increased trauma team response results in alterations in resource use in a population of children <6 years, especially in those least injured.

Methods:

We conducted a retrospective before and after study of children <6 years sustaining blunt trauma and meeting defined prehospital criteria. We compared hospitalization rates and missed injuries (injuries identified after discharge from the emergency department/hospital) among patients with and without an upgraded trauma team response. We compared the computed tomography (CT) rate and laboratory testing rate among minimally injured patients (Injury Severity Score [ISS] 6).

Results:

We enrolled 352 patients with 180 (mean age 2.7 ± 1.5 years) in the upgrade cohort and 172 (mean age 2.6 ± 1.5 years) in the no-upgrade cohort. Independent predictors of hospital admission in a regression analysis included: Glasgow Coma Scale <14 (odds ratio [OR]=11.4, 95% confidence interval [CI] 2.3, 56), ISS (OR=1.55, 95% CI 1.33, 1.81), and evaluation by the upgrade trauma team (OR=5.66, 95% CI 3.14, 10.2). In the 275 patients with ISS <6, CT (relative risk=1.34, 95% CI 1.09, 1.64) and laboratory tests (relative risk=1.71, 95% CI 1.39, 2.11) were more likely to be obtained in the upgrade cohort as compared to the no-upgrade cohort. We identified no cases of a missed diagnosis.

Conclusion:

Increasing the trauma team response based upon young age results in increased resource use without altering the rate of missed injuries. In hospitals with emergency department physicians capable of evaluating and treating injured children, increasing ED trauma team resources solely for young age of the patient is not recommended.

A review of the literature on the validity of mass casualty triage systems with a focus on chemical exposures

INTRODUCTION

Mass casualty incidents (MCIs) include natural (eg, earthquake) or human (eg, terrorism or technical) events. They produce an imbalance between medical needs and resources necessitating the use of triage strategies. Triage of casualties must be performed accurately and efficiently if providers are to do the greatest good for the greatest number. There is limited research on the validation of triage system efficacy in determining the priority of care for victims of MCI, particularly those involving chemicals.

OBJECTIVE

To review the literature on the validation of current triage systems to assign on-site treatment status codes to victims of mass casualties, particularly those involving chemicals, using actual patient outcomes.

METHODS

The focus of this article is a systematic review of the literature to describe the influences of MCIs, particularly those involving chemicals, on current triage systems related to the on-site assignment of treatment status codes to a victim and the validation of the assigned code using actual patient outcomes.

RESULTS

There is extensive literature published on triage systems used for MCI but only four articles used actual outcome data to validate mass casualty triage outcomes including three for chemical events. Currently, the amount and type of data collected are not consistent or standardized and definitions are not universal.

CONCLUSIONS

Current literature does not provide needed evidence on the validity of triage systems for MCI in particular those involving chemicals. Well designed studies are needed to validate the reliability, sensitivity, and specificity of triage systems used for MCI including those involving chemicals.

Is a two-tier trauma team activation system the most effective way to manage trauma in the UK?

This review describes the evidence exploring the use of a two-tier trauma team activation system, reviewing the background, history, data available and potential benefits and downsides. The current evidence suggests that a two-tier system may be a lean, cost-effective system, focussed on patient outcome, which could be implemented throughout the UK. Despite its current use in some hospitals, there is limited data from similar systems supporting this in a UK setting. Specific activation criteria need to be validated to ensure appropriate activation of trauma teams, ensuring optimal patient outcome and ensuring best practice.

What is optimal timing for trauma team alerts? A retrospective observational study of alert timing effects on the initial management of trauma patients

Background

Trauma teams improve the initial management of trauma patients. Optimal timing of trauma alerts could improve team preparedness and performance while also limiting adverse ripple effects throughout the hospital. The purpose of this study was to evaluate how timing of trauma team activation and notification affects initial in-hospital management of trauma patients.

Methods

Data from a single hospital trauma care quality registry were matched with data from a trauma team alert log. The time from patient arrival to chest X-ray, and the emergency department length of stay were compared with the timing of trauma team activations and whether or not trauma team members received a preactivation notification.

Results

In 2009, the trauma team was activated 352 times; 269 times met the inclusion criteria. There were statistically significant differences in time to chest X-ray for differently timed trauma team activations (P = 0.003). Median time to chest X-ray for teams activated 15–20 minutes prearrival was 5 minutes, and 8 minutes for teams activated <5 minutes before patient arrival. Timing had no effect on length of stay in the emergency department (P = 0.694). We found no effect of preactivation notification on time to chest X-ray (P = 0.474) or length of stay (P = 0.684).

Conclusion

Proactive trauma team activation improved the initial management of trauma patients. Trauma teams should be activated prior to patient arrival.

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.

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.

Evaluation of a university hospital trauma team activation protocol

BACKGROUND

Admission with a multidisciplinary trauma team may be vital for the severely injured patient, as this facilitates rapid diagnosis and treatment. On the other hand, patients with minor injuries do not need the trauma team for adequate care. Correct triage is important for optimal resource utilization. The aim of the study was to evaluate our criteria for activating the trauma team, and identify suboptimal criteria that might be changed in the interest of precision.

METHODS

The study is an observational, retrospective cohort-study. All patients admitted with the trauma team (n = 382), all severely injured (Injury Severity Score (ISS) >15) (n = 161), and all undergoing an emergency procedure aimed at counteracting compromised airways, respiration or circulation at our hospital (n = 142) during 2006-2007 were included. Data were recorded from the admission records and the electronic patient records. The trauma team activation protocol was evaluated against the occurrence of severe injury and the occurrence of emergency procedures.

RESULTS

A total of 441 patients were included. The overtriage was 71% and undertriage 32% when evaluating against ISS >15 as the standard of reference. When occurrence of emergency procedures was held as the standard of standard of reference, the over- and undertriage was 71% and 21%, respectively. Mechanism of injury-criteria for trauma team activation contributed the most to overtriage. The emergency procedures performed were mostly endotracheal intubation and external fixation of fractures. Less than 3% needed haemostatic laparotomy or thoracotomy. Approximately 2/3 of the overtriage represented isolated head or cervical spine injuries, and/or interhospital transfers.

CONCLUSIONS

The over- and undertriage of our protocol are both too high. To decrease overtriage we suggest omissions and modifications of some of the criteria. To decrease undertriage, transferred patients and patients with head injuries should be more thoroughly assessed against the trauma team activation criteria.
