Traumatic injury in Australia and New Zealand

Application of a dual-track teaching model combining CBL and TBL based on the BOPPPS model in trauma care nursing training

AIM

To compare the application effects of a dual-track teaching model combining Case-based Learning (CBL) and Team-based Learning (TBL) based on the BOPPPS model in trauma care nursing training, aiming to provide references for the continuous optimization of domestic trauma care nursing training courses.

BACKGROUND

Planned and targeted standardized training for trauma-related nursing staff is necessary. Trauma care training started earlier abroad than in China, highlighting a critical need to enhance the quality of trauma training.

METHODS

A quasi-experimental research design was used. The control group consisted of 1267 trainees who participated in 12 sessions of CTCT®-N 1.0 training from April 2021 to May 2023, using a teaching method that combined BOPPPS-based classroom lectures with workshop demonstrations. The experimental group consisted of 1212 trainees who participated in 12 sessions of CTCT®-N 2.0 training from June to October 2023, using a dual-track teaching model based on BOPPPS, which integrated case-based classroom lectures with group team-based training.

RESULTS

Post-training assessment scores for the experimental group (86.42 ± 12.27) were higher than those for the control group (74.65 ± 19.56) (t = -4.213, p < 0.001). The experimental group scored an average of 83.36 ± 9.37 in the comprehensive assessment of trauma treatment, with satisfaction ratings above 4 points.

CONCLUSION

The dual-track teaching model combining CBL and TBL based on the BOPPPS framework can enhance the educational effectiveness and satisfaction of trauma care nursing training.

The Australian Trauma Registry (ATR): a leading clinical quality registry

Operating since 2012 under the auspices of the Australian Trauma Quality Improvement Program (AusTQIP), the Australian Trauma Registry (ATR) has established itself as a leading clinical quality registry (CQR). Initially developed as a national program for improved safety and quality trauma care across Australian trauma centers, it has since expanded to include New Zealand, becoming one of the few bi-national trauma registries. The registry has recorded close to 100,000 episodes of care for severely injured patients since its inception, with 10.7% growth in annual inclusions. The ATR, administered by the National Trauma Research Institute (NTRI), monitors the continuum of trauma care from pre-hospital settings, to discharge from definitive care. Collection and analysis of data about severely injured trauma patients, their injuries, management and outcomes, aims to inform future improvements to health service provision and reduce preventable morbidity and mortality.

Perspectives of major traumatic injury survivors on accessibility and quality of rehabilitation services in rural Australia

PURPOSE

For the 30% of Australians who live in rural areas, access to rehabilitation services after sustaining a major traumatic injury can be challenging. This study aimed to explore the experience of rural major traumatic injury survivors accessing rehabilitation services.

MATERIALS AND METHODS

Semi-structured interviews were conducted with 21 rural major traumatic injury survivors (M_age = 47.86; SD = 11.35; Range: 21-61) who were an average of seven years post-injury (SD = 3.10; Range: 3.25-13.01). Transcribed interviews were thematically analysed.

RESULTS

Four themes were identified: (1) Managing the transition back to local services, (2) Independence and determination to get better, (3) Rehabilitation is an ongoing process, and (4) Limited service access and quality. While injury-related symptoms persisted for many participants, they expressed strong determination for independence and self-management of their recovery. Barriers to accessing rehabilitation services included poor knowledge of local services, travel burden, financial costs, and a lack of local practitioners experienced in major traumatic injury rehabilitation. Facilitating factors included financial, psychological, community, and informal supports.

CONCLUSIONS

To support recovery, future rural service models should improve consideration of factors resulting from living at a distance to services and harness independence to self-manage.IMPLICATIONS FOR REHABILITATIONRural major traumatic injury survivors need support to navigate numerous barriers to accessing rehabilitation services.Rural participants expressed their preference for greater involvement in planning their transition back home following hospitalisation and help to link with available services in their local area.Specialist training and support for rural rehabilitation practitioners is needed, to effectively treat impairments related to major traumatic injury, particularly psychological and cognitive difficulties.Future service delivery models should incorporate methods to locate rural services; facilitate telehealth access and client self-management; and provide financial and mental health support to both rural survivors of major traumatic injury and their carers.

Prehospital activation of a coordinated multidisciplinary hospital response in preparation for patients with severe hemorrhage. A state-wide data linkage study of the New South Wales "Code Crimson" pathway

BACKGROUND

Hemorrhage is a leading cause of preventable death in trauma. Prehospital medical teams can streamline access to massive transfusion and definitive hemorrhage control by alerting in-hospital trauma teams of suspected life-threatening bleeding in unstable patients. This study reports the initial experience of an Australian "Code Crimson" pathway facilitating early multidisciplinary care for these patients.

METHODS

This data-linkage study combined prehospital databases with a trauma registry of patients with an ISS > 12 between 2017 and 2019. Four groups were created; prehospital Code Crimson (CC) activation with and without in-hospital links and patients with inpatient treatment consistent with CC, without one being activated. Diagnostic accuracy was estimated using capture-recapture methodology to replace the missing cell (no prehospital CC and ISS < 12).

RESULTS

Of 72 prehospital CC patients, 50 were linked with hospital data. Of 154 potentially missed patients, 42 had a prehospital link. Most CC patients were young males who sustained blunt trauma and required more prehospital interventions than non-CC patients. CC patients had more multisystem trauma, especially complex thoracic injuries (80%), while missed-CC patients more frequently had single organ injuries (59%). CC patients required fewer hemorrhage control procedures (60% vs 86%). Lower mortality was observed in CC patients despite greater hospital and ICU length of stay. Despite a low sensitivity (0.49, 95%CI 0.38-0.61) and good specificity (0.92, 95%CI 0.86-0.96), the positive likelihood ratio was acceptable (6.42, 95%CI 3.30-12.48).

CONCLUSIONS

The initiation of a state-wide Code Crimson process was highly specific for the need for hemorrhage control intervention in hospital, but further work is required to improve the sensitivity of prehospital activation. Patients who had a Code Crimson activation sustained more multisystem trauma but had lower mortality than those who did not. These results guide measures to improve this pathway.

The epidemiology and outcomes of vascular trauma in Gold Coast, Australia: Institutional experience at a level 1 trauma centre

BACKGROUND

Vascular trauma is a complex and evolving area. Unlike internationally, the epidemiology of vascular trauma is not well documented in Australia; the most recent study was published in 2013. Gold Coast University Hospital (GCUH) is a level 1 trauma centre in Queensland, Australia. The aim of this study was to describe the epidemiology and outcomes of vascular trauma at a level 1 trauma centre, and compare these with the Australian and international literature.

METHODS

All individuals who presented to GCUH between January 2014 and December 2019 with vascular injury were retrieved from the GCUH prospective trauma database. A descriptive analysis was undertaken on this cohort.

RESULTS

The incidence of vascular trauma as a percentage of total trauma remained stable over the study period. The study included 5454 trauma admissions to GCUH, of which 213 sustained vascular injuries. Males were more likely to be injured and blunt trauma was more common than penetrating. Blunt trauma was associated with increased injury complexity. The mortality rate was 8.5% and 10 patients required amputation.

CONCLUSIONS

The proportion of vascular injuries as a percentage of total trauma in Australia is higher than in previous studies. Vascular trauma causes significant injuries and has a higher mortality rate than general trauma.

Characteristics and Outcomes of Critically Ill Trauma Patients in Australia and New Zealand (2005-2017)

OBJECTIVES

To compare the characteristics of adults admitted to the ICU in Australia and New Zealand after trauma with nonelective, nontrauma admissions. To describe trends in hospital mortality and rates of discharge home among these two groups.

DESIGN

Retrospective review (2005-2017) of the Australia and New Zealand Intensive Care Society's Center for Outcome and Resource Evaluation Adult Patient Database.

SETTING

Adult ICUs in Australia and New Zealand.

PATIENTS

Adult (≥17 yr), nonelective, ICU admissions.

INTERVENTION

Observational study.

MEASUREMENTS AND MAIN RESULTS

We compared 77,002 trauma with 741,829 nonelective, nontrauma patients. Trauma patients were younger (49.0 ± 21.6 vs 60.6 ± 18.7 yr; p < 0.0001), predominantly male (73.1% vs 53.9%; p < 0.0001), and more frequently treated in tertiary hospitals (74.7% vs 45.8%; p < 0.0001). The mean age of trauma patients increased over time but was virtually static for nonelective, nontrauma patients (0.72 ± 0.02 yr/yr vs 0.03 ± 0.01 yr/yr; p < 0.0001). Illness severity increased for trauma but fell for nonelective, nontrauma patients (mean Australia and New Zealand risk of death: 0.10% ± 0.02%/yr vs -0.21% ± 0.01%/yr; p < 0.0001). Trauma patients had a lower hospital mortality than nonelective, nontrauma patients (10.0% vs 15.8%; p < 0.0001). Both groups showed an annual decline in the illness severity adjusted odds ratio (odds ratio) of hospital mortality, but this was slower among trauma patients (trauma: odds ratio 0.976/yr [0.968-0.984/yr; p < 0.0001]; nonelective, nontrauma: odds ratio 0.957/yr [0.955-0.959/yr; p < 0.0001]; interaction p < 0.0001). Trauma patients had lower rates of discharge home than nonelective, nontrauma patients (56.7% vs 64.6%; p < 0.0001). There was an annual decline in illness severity adjusted odds ratio of discharge home among trauma patients, whereas nonelective, nontrauma patients displayed an annual increase (trauma: odds ratio 0.986/yr [0.981-0.990/yr; p < 0.0001]; nonelective, nontrauma: odds ratio 1.014/yr [1.012-1.016/yr; p < 0.0001]; interaction: p < 0.0001).

CONCLUSIONS

The age and illness severity of adult ICU trauma patients in Australia and New Zealand has increased over time. Hospital mortality is lower for trauma than other nonelective ICU patients but has fallen more slowly. Trauma patients have become less likely to be discharged home than other nonelective ICU patients.

Hypocalcemia in trauma patients: A systematic review

BACKGROUND

During hemorrhagic shock and subsequent resuscitation, pathways reliant upon calcium such as platelet function, intrinsic and extrinsic hemostasis, and cardiac contractility are disrupted. The objective of this systematic review was to examine current literature for associations between pretransfusion, admission ionized hypocalcemia, and composite outcomes including mortality, blood transfusion requirements, and coagulopathy in adult trauma patients.

METHODS

This review was reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. We searched Ovid MEDLINE and grey literature from database inception till May 3, 2020. Case series and reports were excluded. Reference lists of appraised studies were also screened for articles that the aforementioned databases might not have captured. The Newcastle-Ottawa Scale was used to assess study quality.

RESULTS

A total of 585 abstracts were screened through database searching and alternative sources. Six unique full-text studies were reviewed, of which three were excluded. Admission ionized hypocalcemia was present in up to 56.2% of the population in studies included in this review. Admission ionized hypocalcemia was also associated with increased mortality in all three studies, with increased blood transfusion requirements in two studies, and with coagulopathy in one study.

CONCLUSION

Hypocalcemia is a common finding in shocked trauma patients. While an association between admission ionized hypocalcemia and mortality, blood transfusion requirements, and coagulopathy has been identified, further prospective trials are essential to corroborating this association.

Global trends of hand and wrist trauma: a systematic analysis of fracture and digit amputation using the Global Burden of Disease 2017 Study

BACKGROUND

As global rates of mortality decrease, rates of non-fatal injury have increased, particularly in low Socio-demographic Index (SDI) nations. We hypothesised this global pattern of non-fatal injury would be demonstrated in regard to bony hand and wrist trauma over the 27-year study period.

METHODS

The Global Burden of Diseases, Injuries, and Risk Factors Study 2017 was used to estimate prevalence, age-standardised incidence and years lived with disability for hand trauma in 195 countries from 1990 to 2017. Individual injuries included hand and wrist fractures, thumb amputations and non-thumb digit amputations.

RESULTS

The global incidence of hand trauma has only modestly decreased since 1990. In 2017, the age-standardised incidence of hand and wrist fractures was 179 per 100 000 (95% uncertainty interval (UI) 146 to 217), whereas the less common injuries of thumb and non-thumb digit amputation were 24 (95% UI 17 to 34) and 56 (95% UI 43 to 74) per 100 000, respectively. Rates of injury vary greatly by region, and improvements have not been equally distributed. The highest burden of hand trauma is currently reported in high SDI countries. However, low-middle and middle SDI countries have increasing rates of hand trauma by as much at 25%.

CONCLUSIONS

Certain regions are noted to have high rates of hand trauma over the study period. Low-middle and middle SDI countries, however, have demonstrated increasing rates of fracture and amputation over the last 27 years. This trend is concerning as access to quality and subspecialised surgical hand care is often limiting in these resource-limited regions.

The prognostic value of platelet-to-lymphocyte ratio on in-hospital mortality in admitted adult traffic accident patients

BACKGROUND

The predictive value of platelet-to-lymphocyte ratio (PLR) in acute illness is well known, but further evaluation is needed in traffic accident patients.

METHODS

This retrospective observational study enrolled consecutive adult patients involved in traffic accidents who were admitted to the study hospital's emergency department during 1 year. The initial platelet and lymphocyte counts after arrival at the emergency department were the variables of interest. The primary outcome was in-hospital mortality. Data on baseline characteristics, comorbidities, and physiological and laboratory variables were collected. Multivariate Cox proportional hazard modelings were used to identify the variables independently associated with the outcome.

RESULTS

A total of 1,522 traffic accident patient were screened, and 488 patients were enrolled. In all, 43 (8.8%) patients died in the hospital. The median PLR was 115.3 (interquartile range 71.3;181.8). The in-hospital mortality rate of the 1st tertile of PLR (21.5%) was significantly higher than the rates of the 2nd (2.5%) and 3rd (2.5%) tertiles. The area under the receiver operating characteristic curve of PLR for in-hospital survival was 0.82 (95% confidential interval [CI], 0.74-0.89), which was greater than that of lymphocyte count (0.72; 95% CI 0.63-0.81) and platelet count (0.67; 95% CI 0.57-0.76). The Kaplan-Meier curves showed a significant difference in survival between the tertiles (p<0.001). The Cox regression model showed that the 2nd tertile of PLR was independently associated with lower in-hospital mortality (adjusted hazard ratio 0.30; 95% CI, 0.09-0.98), compared to the 1st tertile.

CONCLUSION

PLR was significantly associated with an increased risk of in-hospital mortality in admitted adult traffic accident patients.

Pre-injury health status of major trauma patients with orthopaedic injuries

BACKGROUND

Pre-injury health status is an important determining factor of long-term outcomes after orthopaedic major trauma. Determining pre-injury health status of major trauma patients with orthopaedic injuries is also important for evaluating the change from pre to post-injury health status.

OBJECTIVES

Describe pre-injury health statuses reported at three different time points (6, 12 and 24 months) after injury and compare these with Australian normative values; determine the agreement between pre-injury health status collected at multiple time points post-injury; and identify factors associated with reporting better pre-injury health status.

MATERIALS AND METHODS

A registry-based cohort study was conducted. Major trauma patients with orthopaedic injuries captured by the Victorian State Trauma Registry with a date of injury from January 2009 to December 2016 were included. Pre-injury health status (measured using the EuroQol-Visual Analogue Scale (EQ-VAS)), reported 6, 12 and 24 months post-injury, was compared against Australian population normative values. The Bland-Altman method of comparison was used to determine the agreement between pre-injury EQ-VAS scores reported 6 to 12 and 6 to 24 months post-injury. Mixed effects ordinal logistic regression was used to determine factors associated with reporting better pre-injury health status.

RESULTS

A total of 3,371 patients were eligible for the study. The median (IQR) pre-injury EQ-VAS score reported 6, 12 and 24 months post-injury was 90 (85-100) out of 100. Participants' pre-injury EQ-VAS scores reported 6, 12 and 24 months post-injury were significantly higher than Australian population normative values. Pre-injury EQ-VAS scores reported 6 months post-injury agreed with pre-injury EQ-VAS scores reported 12 and 24 months post-injury. A significant association exists between pre-injury health status and age, comorbidities, injury characteristics, socioeconomic status and pre-injury work status.

CONCLUSIONS

People with orthopaedic major trauma have better pre-injury health compared to the general Australian population. Therefore, population-specific values should be used as baseline measures to evaluate orthopaedic trauma outcomes. Pre-injury health status values reported at three different post-injury time points were comparable. If conducting a retrospective pre-injury health evaluation, researchers need be aware of factors that influence self-reporting of pre-injury health status and the response shift that may happen due to encountering injury.

Epidemiology of Trauma Patients Admitted to a Trauma Center in New Delhi, India

Introduction

The rapid economic and automobile growth in India leads to a rapid increase in road traffic accidents (RTAs) and factors affecting it. This study evaluates the epidemiology of trauma patients’ reports to the major trauma center in New Delhi, India.

Materials and methods

The 1,583 patients over 6 months reporting to the casualty of the trauma center attached to Lok Nayak Hospital, New Delhi were included in the study. The patients reporting to the outpatient department as follow-up visits were not included in the study. The data were collected with the help of a structured pro forma.

Results

The data depicted the RTAs as the most common cause affecting adults between 20 years and 40 years. The study reports other risk factors like alcohol intoxication and motorcycle riders. Mostly, the patients present in a semiconscious and disoriented state requiring fluid resuscitation. Abrasions and bruises in the extremities stand out as the most common injury pattern. The fractures suffered were the most common injury suffered by the patients.

Conclusion

Our study shows that RTAs and workplace injuries are the predominant causes of trauma affecting mostly the adults. This study defines the correlation of various parameters with causation and distribution of the trauma in the sample population. This study was performed to improve the understanding of the mode of trauma, severity of injuries, and outcome in our hospital, so that effective prevention and comprehensive management strategies could be made.

Clinical significance

This study signifies the fundamental study for the occurrence, distribution, and prevention of trauma in the society. The acquisition of knowledge of different patterns of trauma patients along with other descriptive factors helps to understand the causation of this disease as well as development of preventive measures. This can form the basis of hospital and regional trauma management strategies.

Pain, Anxiety, and Depression in the First Two Years Following Transport-Related Major Trauma: A Population-Based, Prospective Registry Cohort Study

Objectives

This study aimed to characterize the population prevalence of pain and mental health problems postinjury and to identify risk factors that could improve service delivery to optimize recovery of at-risk patients.

Methods

This population-based registry cohort study included 5,350 adult survivors of transport-related major trauma injuries from the Victorian State Trauma Registry. Outcome profiles were generated separately for pain and mental health outcomes using the “pain or discomfort” and “anxiety or depression” items of the EuroQol Five Dimensions Three-Level questionnaire at six, 12, and 24 months postinjury. Profiles were “resilient” (no problems at every follow-up), “recovered” (problems at six- and/or 12-month follow-up that later resolved), “worsening” (problems at 12 and/or 24 months after no problems at six and/or 12 months), and “persistent” (problems at every follow-up).

Results

Most participants had persistent (pain/discomfort, N = 2,171, 39.7%; anxiety/depression, N = 1,428, 26.2%) and resilient profiles (pain/discomfort, N = 1,220, 22.3%; anxiety/depression, N = 2,055, 37.7%), followed by recovered (pain/discomfort, N = 1,116, 20.4%; anxiety/depression, N = 1,025, 18.8%) and worsening profiles (pain/discomfort, N = 956, 17.5%; anxiety/depression, N = 948, 17.4%). Adjusted multinomial logistic regressions showed increased risk of problems (persistent, worsening, or resolved) vs no problems (resilient) in relation to female sex, middle age, neighborhood disadvantage, pre-injury unemployment, pre-injury disability, and spinal cord injury. People living in rural areas, motorcyclists, pedal cyclists, and people with head, chest, and abdominal injuries had lower risk of problems.

Discussion

Targeted interventions delivered to people with the risk factors identified may help to attenuate the severity and impact of pain and mental health problems after transport injury.

A study of mortality risk factors among trauma referrals to trauma center, Shiraz, Iran, 2017

PURPOSE

Trauma is well known as one of the main causes of death and disability throughout the world. Identifying the risk factors for mortality in trauma patients can significantly improve the quality of care and patient outcomes, as well as reducing mortality rates.

METHODS

In this retrospective cohort study, systematic randomization was used to select 849 patients referred to the main trauma center of south of Iran during a period of six months (February 2017-July 2017); the patients' case files were evaluated in terms of demographic information, pre- and post-accident conditions, clinical conditions at the time of admission and finally, accident outcomes. A logistic regression model was used to analyze the role of factors affecting mortality among subjects.

RESULTS

Among subjects, 60.4% were in the age-group of 15-39 years. There was a 10.4% mortality rate among patients and motor-vehicle accidents were the most common mechanism of injury (66.7%). Aging led to increased risk of fatality in this study. For each unit increase in Glasgow coma scale (GCS), risk of death decreased by about 40% (odds ratio (OR) = 0.63, 95% confidence interval (CI): 0.59-0.67). For each unit increase in injury severe score (ISS), risk of death increased by 10% (OR = 1.11%, 95% CI: 1.08-1.14) and for each unit increase in trauma revised injury severity score (TRISS), there was 18% decrease in the risk of fatality (OR = 0.82, 95% CI: 0.71-0.88).

CONCLUSION

The most common cause of trauma and the most common cause of death from trauma was traffic accidents. It was also found that an increase in the ISS index increases the risk of death in trauma patients, but the increase in GCS, revised trauma score (RTS) and TRISS indices reduces the risk of death in trauma patients. The TRISS indicator is better predictor of traumatic death than other indicators.

Agreement between medical record and administrative coding of common comorbidities in orthopaedic trauma patients

OBJECTIVE

To i) quantify the agreement between comorbidities documented within medical records and an orthopaedic trauma dataset; and ii) compare agreement between these sources before and after the introduction of new comorbidity coding rules in Australian hospitals.

STUDY DESIGN AND SETTING

A random sample of adult (≥ 16 years) orthopaedic trauma patients (n = 400) were extracted from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR). Diagnoses of obesity, arthritis, diabetes and cardiac conditions documented within patients' medical records were compared to ICD-10-AM comorbidity codes (provided by hospitals) for the same admission. Agreement was calculated (Cohen's kappa) before and after the introduction of new coding rules.

RESULTS

All comorbidities had the same or higher prevalence in medical record data compared to coded data. Kappa values ranged from <0.001 (poor agreement) for coronary artery disease to 0.94 (excellent agreement) for type 2 diabetes. There was improvement in agreement between sources for most conditions following the introduction of new coding rules.

CONCLUSION

There has been improvement in the coding of certain comorbidities since the introduction of new coding rules, suggesting that, since 2015, administrative data has improved capacity to capture patients' comorbidity profiles. Consideration must be taken when using the ICD-10-AM data due to its limitations.

Visceral Injuries in Patients with Blunt and Penetrating Abdominal Trauma Presenting to a Tertiary Care Facility in Karachi, Pakistan

Introduction

Abdominal injuries are responsible for 10% of the mortalities due to trauma. Delays in early diagnosis or misdiagnoses are two major reasons for the mortality and morbidity associated with abdominal trauma. The objectives of this study were to determine the frequency of visceral injuries in patients with abdominal trauma and compare the frequency of visceral injuries in patients with blunt and penetrating abdominal trauma.

Methods

We conducted a cross-sectional study from May 2016 to May 2018 of patients presenting to the emergency department (ED) at Jinnah Postgraduate Medical Center in Karachi, Pakistan. Patients were 12 to 65 years old and presented within 24 hours of abdominal trauma. We recorded the type of abdominal visceral injuries, such as liver, spleen, intestine, stomach, mesentery, and pancreas.

Results

The mean patient age was 31 ±13 years. Penetrating trauma was found in most patients (n=72, 51%). Liver injuries were found in 37 patients (26.4%), spleen injuries in 29 patient (20.7%), stomach injuries in eight patients (5.7%), intestine injuries in 67 patients (47.9%), mesentery injuries in 21 patients (15%), and pancreas injuries in nine patients (6.4%). The type of abdominal trauma was found significantly associated with liver injury (p-value 0.021), and intestine injury (p-value <0.001).

Conclusion

Penetrating trauma (51.4%) was more common than blunt trauma (48.5%), and intestines are the most commonly affected by penetrating and blunt trauma injuries (70.1% and 47.8%, respectively). The liver is the most commonly affected (42.85%) in blunt trauma injuries, followed by the spleen (28.5%). The appropriate authorities should consider this information when instituting public health and safety initiatives.

Epidemiology of trauma patients attended by ambulance paramedics in Perth, Western Australia

OBJECTIVE

The aim of the study was to describe the epidemiology of trauma in adult patients attended by ambulance paramedics in Perth, Western Australia.

METHODS

A retrospective cohort study of trauma patients aged ≥16 years attended by St John Ambulance Western Australia (SJA-WA) paramedics in greater metropolitan Perth between 2013 and 2016 using the SJA-WA database and WA death data. Incidence and 30 day mortality rates were calculated. Patients who died prehospital (immediate deaths), on the day of injury (early deaths), within 30 days (late deaths) and those who survived longer than 30 days (survivors) were compared for age, sex, mechanism of injury and acuity level. Prehospital interventions were also reported.

RESULTS

Overall, 97 724 cases were included. A statistically significant increase in the incidence rate occurred over the study period (from 1466 to 1623 per 100 000 population year P ≤ 0.001). There were 2183 deaths within 30 days (n = 2183/97 724, 2.2%). Motor vehicle accidents were responsible for most immediate and early deaths (n = 98/203, 48.3% and n = 72/156, 46.2%, respectively). The majority of transported patients were low acuity (acuity levels 3 to 5, n = 60 594/79 887, 75.8%) and high-acuity patients accounted for 2.7% (n = 2176/79 997). Analgesia administration was the most frequently performed intervention (n = 32 333/80 643, 40.1%), followed by insertion of intravenous catheters (n = 25 060/80 643, 31.1%). Advanced life support interventions such as endotracheal intubation were performed in <1% of patients.

CONCLUSION

The trauma incidence rate increased over time and the majority of patients had low-acuity injuries. Focusing research, training and resources solely on high-acuity patients will not cater for the needs of the majority of patients.

Perspectives of hospital emergency department staff on trauma-informed care for injured children: An Australian and New Zealand analysis

AIM

To examine Australian and New Zealand emergency department (ED) staff's training, knowledge and confidence regarding trauma-informed care for children after trauma, and barriers to implementation.

METHODS

ED staff's perspectives on trauma-informed care were assessed using a web-based self-report questionnaire. Participants included 468 ED staff (375 nursing and 111 medical staff) from hospitals in Australia and New Zealand. Data analyses included descriptive statistics, χ² tests and multiple regressions.

RESULTS

Over 90% of respondents had not received training in trauma-informed care and almost all respondents (94%) wanted training in this area. While knowledge was associated with a respondent's previous training and profession, confidence was associated with the respondent's previous training, experience level and workplace. Dominant barriers to the implementation of trauma-informed care were lack of time and lack of training.

CONCLUSIONS

There is a need and desire for training and education of Australian and New Zealand ED staff in trauma-informed care. This study demonstrates that experience alone is not sufficient for the development of knowledge of paediatric traumatic stress reactions and trauma-informed care practices. Existing education materials could be adapted for use in the ED and to accommodate the training preferences of Australian and New Zealand ED staff.

Trauma and Stem Cells: Biology and Potential Therapeutic Implications

Trauma may cause irreversible tissue damage and loss of function despite current best practice. Healing is dependent both on the nature of the injury and the intrinsic biological capacity of those tissues for healing. Preclinical research has highlighted stem cell therapy as a potential avenue for improving outcomes for injuries with poor healing capacity. Additionally, trauma activates the immune system and alters stem cell behaviour. This paper reviews the current literature on stem cells and its relevance to trauma care. Emphasis is placed on understanding how stem cells respond to trauma and pertinent mechanisms that can be utilised to promote tissue healing. Research involving notable difficulties in trauma care such as fracture non-union, cartilage damage and trauma induced inflammation is discussed further.

Management of paediatric splenic injury in the New South Wales trauma system

Since the 1980's, paediatric surgeons have increasingly managed blunt splenic injury (BSI) in children non-operatively. However, studies in North America have shown higher operation rates in non-paediatric centres and by adult surgeons. This association has not been examined elsewhere.

OBJECTIVE

To investigate the management of BSI in New South Wales (NSW) children, to determine the patient and hospital factors related to the odds of operation. Secondarily, to investigate whether the likelihood of operation varied by year.

METHODS

Children age 0-16 admitted to a NSW hospital between July 2000 and December 2011 with a diagnosis of BSI were identified in the NSW Admitted Patient Data Collection, and linked to deaths data from Registry of Births Deaths and Marriages, and Bureau of Statistics. The operation rate was calculated and compared between different hospital types. Univariable analysis was used to determine patient and hospital factors associated with operative management. The difference in the odds of operation between the oldest data (July 2000-December 2005) and most recent (January 2006-December 2011) was also examined. Multivariable logistic regression with stepwise elimination was then performed to determine likelihood of operative management according to hospital category and era, adjusting for potential confounders.

RESULTS

955 cases were identified, with 101(10.6%) managed operatively. On multivariable analysis, factors associated with operation included age (OR 1.11, 95% CI 1.01-1.18, p<0.05), massive splenic disruption (OR 3.10, 95% CI 1.61-6.19, p<0.001), hollow viscus injury (OR 11.03, 95% CI 3.46-34.28, p<0.001) and transfusion (OR 7.70, 95% CI 4.54-13.16, p<0.001). Management outside a paediatric trauma centre remained significantly associated with operation, whether it be metropolitan adult trauma centre (OR 4.22 95% CI 1.70-10.52, p<0.01), rural trauma centre (OR 3.72 95% CI 1.83-7.83, p<0.001) or metropolitan local hospital (OR 5.23, 95% CI 1.22-18.93 p<0.05). Comparing the 2 eras, the overall operation rate fell, although not significantly, from 12.9% to 8.7% (OR 1.3, 95% CI 0.89-243 p=0.13) CONCLUSION: While Paediatric Surgeons have wholeheartedly adopted non-operative management, away from paediatric centres, children in NSW are still being operated on for BSI unnecessarily. While the factors at play may be complex, further evaluation of the management and movement of injured children within the broad NSW trauma system is required.

Ten years of trauma in the 'top end' of the Northern Territory, Australia: a retrospective analysis

AIM

To examine characteristics of traumatic injury in adults and children at the Royal Darwin Hospital (RDH) over a 10 year period.

METHOD

A retrospective review of the RDH Trauma Registry data from 1 January 2003 to 31 December 2012, with analysis of patient demographics, mechanism of injury, Injury Severity Score (ISS), and outcome.

PARTICIPANTS

Two thousand seven hundred twenty-five patients with an ISS greater than or equal to 9 and met all other study inclusion criteria.

RESULTS

Motor vehicle crashes, assaults and falls consistently remained the three most common mechanisms of injury throughout the 10 year period. Indigenous admissions showed a significant downward trend (p = 0.009). Upward trends were noted in presentations from patients aged greater than 44 (p = 0.002), all-terrain vehicle accidents (p <0.001), and hangings (p = 0.003). No other trends were noted to significant at a p <0.05 level. Admitted Indigenous patients were significantly more likely to be present due to assault (p <0.001) and female patients were more likely to present due to assault, falls and motor vehicle crashes (p <0.01) than their counterparts.

CONCLUSION

Presentations for traumatic injury to Royal Darwin Hospital have remained in the most part, consistently stable for the period of 2003-2012. Though there were some increases/decreases in regard to specific demographics and mechanisms, few were found to be statistically significant at a p < 0.05 level.

The trauma nurse coordinator in England: a survey of demographics, roles and resources

INTRODUCTION

Following the introduction of the regional trauma system in 2012 the role of the trauma nurse coordinator (TNC) has been rolled out. This study aims to determine the demographic and practice profile of nurses performing the TNC role in England.

METHODS

An electronic survey of TNCs across the 18 trauma networks in England was conducted.

RESULTS

Fifty-three TNCs responded (62%) to the survey. Seventeen different role titles identified. The majority of TNCs had an emergency or trauma/orthopaedics clinical background. The largest proportion of time spent was clinical (38%). Least amount of time was spent in the education (7%), and research (3%). Nearly a quarter of respondents (23%) had some form of formal research training, nearly half (47%) were assisting others in research. Over half (55%) of respondents felt that they did not have adequate human resources to conduct their role.

DISCUSSION

This research has provided baseline information about nurses in the role of TNC, their role titles and domains of the role 18 months after the formal introduction of trauma networks in England. There are some marked similarities and differences in the time spent in the different domains of the role between these findings and those published internationally.
