Emergent craniotomy in rural and regional settings: recommendations from a tertiary neurosurgery unit: diagnosis and surgical decision-making.

Largely attributed to the tyranny of distance, timely transfer of patients with major traumatic brain injuries (TBI) from rural or regional hospitals to metropolitan trauma centres is not always feasible. This has warranted emergent craniotomies to be undertaken by non-neurosurgeons at their local hospitals with previous acceptable results reported in regional Australia. Our institution endorses this ongoing potentially life-saving practice when necessary and emphasize the need for neurosurgical units to provide ongoing TBI education to peripheral hospitals. In this first of a two-part narrative review, the authors describe the recommended diagnostic pathway for patients with a suspected TBI presenting to rural or regional hospitals and discuss local surgical management options in the presence or absence of a CT scanner.

Emergent craniotomy in rural and regional settings - recommendations from a tertiary neurosurgery unit: surgical technique and future prospects.

Kenneth G Jamieson described the emergent craniotomy for traumatic brain injuries (TBI) in the rural and regional setting back in 1965 in his book 'A First Notebook Of Head Injury'. Since then, there has been successful use of the technique in peripheral hospitals prior to the safe transfer of patients to metropolitan trauma centres. Although the procedure can be daunting in inexperienced hands, our institution supports ongoing education to continue implementation of trauma craniotomies by non-neurosurgeons if it means another life is potentially saved. Here we describe the surgical technique for an emergent craniotomy and craniectomy. Although the surgical technique has been described elsewhere, we have done so in a simplified 10-step approach with consideration of available resources in the peripheral hospital setting and the added pearls from the experience of a metropolitan neurosurgical unit. We also discuss future prospects for undertaking neurosurgical operations in peripheral hospitals but with intra-operative tele-surgery monitoring and supervision.

Challenges to trauma care delivery for Australian and New Zealand trauma clinicians.

INTRODUCTION: The availability and implementation of evidence-based care is essential to achieving safe, quality trauma patient outcomes. Little is documented, however, about the challenges trauma clinicians face in their day-to day practice, or their views on the availability of evidence. This paper presents the most significant clinical practice challenges reported by multidisciplinary trauma care professionals in Australia and New Zealand, in particular those that may be resolved with focussed research or enhanced implementation activity. METHODS: An exploratory survey of trauma professionals from relevant Australia and New Zealand professional organisations was conducted between September 2018 and February 2019 using the Snowballing Method. Participants were recruited via a non-random sampling technique to complete an online survey. Thematic analyses were conducted. RESULTS: There were nine significant clinical practice challenge themes in trauma care, arising from 287 individual clinical practice challenges reported. The most reported being clinical management (bleeding, spinal, older patients) and operationalisation of the trauma system. There was no consensus as to the availability of evidence to guide each theme. CONCLUSION: Future research should seek to address the clinical practice challenge of Australian and New Zealand trauma community to enable safe, quality trauma patient outcomes.

Inclusion of 'minor' trauma cases provides a better estimate of the total burden of injury: Queensland Trauma Registry provides a unique perspective.

INTRODUCTION: Injury is recognised as a frequent cause of preventable mortality and morbidity; however, incidence estimates focusing only on the extent of mortality and major trauma may seriously underestimate the magnitude of the total injury burden. There currently exists a paucity of information regarding minor trauma, and the aim of this study was to increase awareness of the contribution of minor trauma cases to the total burden of injury. METHODS: The demographics, injury details, acute care factors and outcomes of both minor trauma cases and major trauma cases were evaluated using data from the state-wide trauma registry in Queensland, Australia, from 2005 to 2010. The impact of changes in Abbreviated Injury Scale (AIS) versions on the classification of minor and major injury cases was also assessed. RESULTS: Over the 6-year period, minor cases [Injury Severity Score (ISS) ≤ 12] accounted for almost 90% of all trauma included on the Queensland Trauma Registry (QTR). These cases utilised more than half a million acute care bed days, underwent more than 66,500 operations, and accounted for more than 48,000 patient transport episodes via road ambulance, fixed wing aircraft, or helicopter. Furthermore, more than 5800 minor trauma cases utilised in-hospital rehabilitation services; almost 3000 were admitted to an ICU; and more than 20,000 were admitted to hospital for greater than one week. When using the contemporary criteria for classifying trauma (AIS 08), the proportion of cases classified as minor trauma (87.7%) and major trauma (12.3%) were similar to the proportion using the traditional criteria for AIS90 (87.9% and 12.1%, respectively). CONCLUSIONS: This evaluation of minor trauma cases admitted to public hospitals in Queensland detected high levels of demand placed on trauma system resources in terms of acute care bed days, operations, ICU admissions, in-hospital rehabilitation services and patient transportation, and which are all associated with high cost. These data convincingly demonstrate the significant burden of injury imposed by minor trauma cases serious enough to be admitted to hospital.

Traumatic abdominal wall herniation: case series review and discussion.

BACKGROUND: Traumatic abdominal wall hernia (TAWH) is a rare type of hernia occurring secondary to blunt trauma to the abdomen. Its management remains controversial within the surgical community, mainly due to complexities in diagnosis, appropriate surgical approach and timing of closure. METHOD: Cases were identified retrospectively, via interviews with trauma surgeons at a Tertiary Trauma Centre, the Royal Brisbane & Women's Hospital, in Brisbane, Australia. In addition, data were collected via in-house trauma and operative databases. RESULTS: Five cases of TAWH were identified over a 3-year period. All cases involved injuries sustained from motor vehicle or motor bike accidents. Diagnosis was purely clinical in one case and clinically suspected, then confirmed by computed tomography in the remainder. Herniation was managed by immediate closure in one instance, delayed/staged closure in three cases and conservative management in the remainder. In addition, three of the five patients were obese. At minimal 3-month follow-up, no evidence of recurrence of herniation was present in four of the five cases. One case was lost to follow-up. CONCLUSIONS: TAWH is a complex injury to manage and no one approach is all encompassing. Correct diagnosis is essential as this allows proper planning for the method and timing of repair. This series highlighted that incorrect seatbelt placement, especially in the obese population, may be a risk factor for increased incidence of TAWH.

The epidemiology of horse-related injuries for different horse exposures, activities, and age groups in Queensland, Australia.

BACKGROUND: The dangers associated with horse riding, a popular activity throughout Australia, are well documented; yet, few studies have comprehensively described injuries caused by horses to nonriders. This study aimed to facilitate targeted injury prevention strategies and appropriate trauma management by describing all horse-related injuries, for both riders and nonriders, in Queensland, and identifying those at greatest risk. METHODS: Horse-related injury data from 2005 to 2009 were extracted from the Queensland Trauma Registry. Descriptive comparisons were undertaken for demographic, injury, and acute care characteristics between riders and nonriders, between pediatric and adult cases, and between sports/leisure and work injuries. The relative risk of surgery by sex and between riders and nonriders was assessed. RESULTS: More than 25% of injuries occurred in people not riding a horse. Nonriders sustained a significantly higher proportion of internal organ injuries, open wounds, as well as facial and pelvic/abdominal injuries. Females accounted for more than 80% of children who were injured while riding a horse. For adults, 25% were injured while working, and more than 66% of injured workers were male. Injuries most commonly occurred in regional areas. Surgery was most common among children, nonriders, and those with Injury Severity Score (ISS) of 1 to 8. The likelihood of surgery was 25% higher for nonriders (95% confidence interval, 1.14-1.38%). CONCLUSION: Horse-related injuries are most prevalent in identifiable populations, particularly young female riders and adult males injured while working. Injuries inflicted by horses to nonriders contribute more than 27% of all horse-related injuries; however, most previous research has been limited to injured riders. Compared with riders, nonriders more frequently sustain internal, facial, and pelvic injuries; are male; and undergo surgery. The results of this study may be used to tailor prevention strategies and inform trauma management specific to the type of horse exposure, patient age, and activity engaged in when injured. LEVEL OF EVIDENCE: Epidemiologic study, level III.

Standardising trauma monitoring: the development of a minimum dataset for trauma registries in Australia and New Zealand.

INTRODUCTION: Trauma registries are central to the implementation of effective trauma systems. However, differences between trauma registry datasets make comparisons between trauma systems difficult. In 2005, the collaborative Australian and New Zealand National Trauma Registry Consortium began a process to develop a bi-national minimum dataset (BMDS) for use in Australasian trauma registries. This study aims to describe the steps taken in the development and preliminary evaluation of the BMDS. METHODS: A working party comprising sixteen representatives from across Australasia identified and discussed the collectability and utility of potential BMDS fields. This included evaluating existing national and international trauma registry datasets, as well as reviewing all quality indicators and audit filters in use in Australasian trauma centres. After the working party activities concluded, this process was continued by a number of interested individuals, with broader feedback sought from the Australasian trauma community on a number of occasions. Once the BMDS had reached a suitable stage of development, an email survey was conducted across Australasian trauma centres to assess whether BMDS fields met an ideal minimum standard of field collectability. The BMDS was also compared with three prominent international datasets to assess the extent of dataset overlap. Following this, the BMDS was encapsulated in a data dictionary, which was introduced in late 2010. RESULTS: The finalised BMDS contained 67 data fields. Forty-seven of these fields met a previously published criterion of 80% collectability across respondent trauma institutions; the majority of the remaining fields either could be collected without any change in resources, or could be calculated from other data fields in the BMDS. However, comparability with international registry datasets was poor. Only nine BMDS fields had corresponding, directly comparable fields in all the national and international-level registry datasets evaluated. CONCLUSION: A draft BMDS has been developed for use in trauma registries across Australia and New Zealand. The email survey provided strong indications of the utility of the fields contained in the BMDS. The BMDS has been adopted as the dataset to be used by an ongoing Australian Trauma Quality Improvement Program.

Epidemiology of traumatic epidural hematoma in young age.

BACKGROUND: Epidural hematoma (EDH) is a major traumatic brain injury and a potentially life-threatening condition, with the mortality rate in the young age group varying across studies. The aim of this analysis was to investigate the magnitude of traumatic EDH in young patients aged 0 year to 24 years in Queensland, Australia. METHODS: Study patients presented to the emergency department of 14 public hospitals participating in the Queensland Trauma Registry during 2005 to 2007 and were diagnosed and admitted for treatment of EDH. Age group comparisons were performed for demographic, injury, treatment, operation details, and outcome-related variables. RESULTS: We identified 224 young patients with traumatic EDH. The most frequent cause of injury was a fall in the 0 year to 9 years age groups and road traffic crash in those aged 10 years to 24 years. Almost 81% of the EDH cases were due to accidental injury, 17% due to assault, with the remainder due to self-harm and undetermined intent. Skull fracture was present in 75% of the study patients. Neurosurgical operations were performed on 40%. The overall Injury Severity Score adjusted in-hospital mortality rate was 4.8%. The odds of in-hospital mortality was 2.5 (95% confidence interval, 0.8-8.2) compared with older patients (25-64 years). CONCLUSIONS: The results indicate that the Injury Severity Score adjusted in-hospital mortality rates for young patients with EDH were 4.8%. Given the limited information on morbidity resulting from EDH, further analysis to examine modifiable factors for better management and to evaluate survivor's long-term health outcomes via a longitudinal follow-up study is warranted.

Characteristics and outcomes of injury patients in an Aboriginal and Torres Strait Islander population--Queensland Trauma Registry, Australia.

INTRODUCTION: There are few published data for the magnitude of injury-related health problems in indigenous people such as Aboriginal and Torres Strait Islanders. The objective of our study was to compare the characteristics and outcomes of injury in the indigenous population to the non-indigenous population, who are living in Queensland, Australia. METHODS: Participants were injured patients who presented to the emergency department for treatment and admitted to 15 public hospitals participating in the Queensland Trauma Registry (QTR) during 2003-2005. RESULTS: Amongst 38,036 injured patients, 1847 patients were identified as indigenous and 35,530 as non-indigenous. Compared to the non-indigenous group, the indigenous group was significantly younger with no difference by gender. The injury severity score (ISS) and percentage of major injury (ISS > or = 16) were lower in the indigenous group. Indigenous patients had a significantly higher percentage of penetrating type injuries compared to non-indigenous (19.5% vs. 12.5%). The age- and injury severity-adjusted mortality rate was also significantly higher in indigenous. In age-stratified logistic regression analysis, the injury severity-adjusted odds for mortality was 3.0 times higher [95% confidence interval (95% CI): 1.6-5.5] in the indigenous, compared to the non-indigenous group, in 40-64-year olds, whilst increased odds in other age groups were not statistically significant. CONCLUSION: Our results indicate that middle-aged indigenous patients are more likely to die due to injury compared to non-indigenous patients. This suggests that strategies are required to improve outcomes particularly in the most affected injury patient group.

Contemporary New Zealand coefficients for the Trauma Injury Severity Score: TRISS(NZ).

AIMS: To develop local contemporary coefficients for the Trauma Injury Severity Score in New Zealand, TRISS(NZ), and to evaluate their performance at predicting survival against the original TRISS coefficients. METHODS: Retrospective cohort study of adults who sustained a serious traumatic injury, and who survived until presentation at Auckland City, Middlemore, Waikato, or North Shore Hospitals between 2002 and 2006. Coefficients were estimated using ordinary and multilevel mixed-effects logistic regression models. RESULTS: 1735 eligible patients were identified, 1672 (96%) injured from a blunt mechanism and 63 (4%) from a penetrating mechanism. For blunt mechanism trauma, 1250 (75%) were male and average age was 38 years (range: 15-94 years). TRISS information was available for 1565 patients of whom 204 (13%) died. Area under the Receiver Operating Characteristic (ROC) curves was 0.901 (95%CI: 0.879-0.923) for the TRISS(NZ) model and 0.890 (95% CI: 0.866-0.913) for TRISS (P<0.001). Insufficient data were available to determine coefficients for penetrating mechanism TRISS(NZ) models. CONCLUSIONS: Both TRISS models accurately predicted survival for blunt mechanism trauma. However, TRISS(NZ) coefficients were statistically superior to TRISS coefficients. A strong case exists for replacing TRISS coefficients in the New Zealand benchmarking software with these updated TRISS(NZ) estimates.

Using Trauma Injury Severity Score (TRISS) variables to predict length of hospital stay following trauma in New Zealand.

AIM: To develop and assess the predictive capabilities of a statistical model that relates routinely collected Trauma Injury Severity Score (TRISS) variables to length of hospital stay (LOS) in survivors of traumatic injury. METHOD: Retrospective cohort study of adults who sustained a serious traumatic injury, and who survived until discharge from Auckland City, Middlemore, Waikato, or North Shore Hospitals between 2002 and 2006. Cubic-root transformed LOS was analysed using two-level mixed-effects regression models. RESULTS: 1498 eligible patients were identified, 1446 (97%) injured from a blunt mechanism and 52 (3%) from a penetrating mechanism. For blunt mechanism trauma, 1096 (76%) were male, average age was 37 years (range: 15-94 years), and LOS and TRISS score information was available for 1362 patients. Spearman's correlation and the median absolute prediction error between LOS and the original TRISS model was p=0.31 and 10.8 days, respectively, and between LOS and the final multivariable two-level mixed-effects regression model was p=0.38 and 6.0 days, respectively. Insufficient data were available for the analysis of penetrating mechanism models. CONCLUSIONS: Neither the original TRISS model nor the refined model has sufficient ability to accurately or reliably predict LOS. Additional predictor variables for LOS and other indicators for morbidity need to be considered.

The Queensland Trauma Plan project.

BACKGROUND: The aim of this paper is to outline the development of 'A Trauma Plan for Queensland'. Injury is one of Australia's National Health Priorities. The full impact of injury, including early death, reduction in quality of life and the social and emotional costs to individuals and the community are immeasurable. The direct health-care costs alone amounted to A dollars 4.13 bn in 2000-2001. Queensland has one of the highest rates of injury in Australia. An estimated 1500 Queenslanders die each year as a result of major traumatic injury and it is the single most common cause of death between the ages of 1 and 35 years. METHODS: The Queensland Trauma Plan was based on a detailed analysis of the management and outcome of trauma in Queensland and used an extensive process of stakeholder consultation to identify proposals for system improvement. Sequential workshops helped identify the issues and strategies for system improvement. These proposals were condensed into a high-level strategic plan, which has now been endorsed by the Queensland Government. RESULTS: The Trauma Plan identifies service enhancements and the improved coordination required to support ongoing policy development, research and education. The Plan outlines a future direction for the development of trauma services and the system and structures required to support that development. CONCLUSION: The Trauma Plan holds potential as a model for the development of future trauma services and injury prevention programmes. The process shows the value of engagement of clinicians and others into the policy development and planning processes. The outcome reinforces the value of taking a whole of community, coordinated and collaborative approach to injury prevention and management.

Tackling the burden of injury in Australasia: developing a binational trauma registry.

Existing trauma registries in Australia and New Zealand play an important role in monitoring the management of injured patients. Over the past decade, such monitoring has been translated into changes in clinical processes and practices. Monitoring and changes have been ad hoc, as there are currently no Australasian benchmarks for "optimal" injury management. A binational trauma registry is urgently needed to benchmark injury management to improve outcomes for injured patients.
