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

Interpersonal violence and violent re-injury in the Northern Territory

OBJECTIVES

To analyse incidence of prior emergency department presentations for interpersonal violence and demographics for a series of hospital admissions for interpersonal violence injuries.

DESIGN

Retrospective analysis of trauma registry.

SETTING

A tertiary hospital and primary referral centre for trauma in the Top End of the Northern Territory.

PARTICIPANTS

Patients hospitalised from 2010 to 2015 for injuries due to interpersonal violence with an injury severity score > 9.

MAIN OUTCOME MEASURES

Patient demographics, injury location, assault mechanism, alleged perpetrator, time/day of event, alcohol involvement, clinical outcome and prior emergency department presentations for interpersonal violence.

RESULTS

A total of 248 admissions for patients with Injury Severity Score > 9 due to interpersonal violence were identified. Indigenous females over-represented non-Indigenous females (35.4% vs 5.0%, P < .001). The majority of victims had evidence of alcohol intake at presentation. Victims of single-punch head injuries were mostly male and non-Indigenous, whilst Indigenous persons experienced significantly more blunt and penetrating weapon injuries (66.7% and 68.1%). Forty-three per cent of patients had a preceding emergency department presentation for interpersonal violence; female gender, Indigenous ethnicity, evidence of alcohol intake, and urban location of injury were independent risk factors for prior interpersonal violence presentation.

CONCLUSIONS

Interpersonal violence is a recurring disease for a just under half of those presenting to a Top End hospital with moderate to severe injuries. Indigenous ethnicity, female gender and evidence of alcohol intake are predictive of prior interpersonal violence presentations. Patient under-reporting and incomplete data may underestimate the true prevalence of interpersonal violence presentations in rural and remote locales.

Quad bike injuries at an Australian regional hospital: a trauma registry review

BACKGROUND

Quad bikes are a prominent cause of morbidity and mortality in Australia in both agriculture and recreation. This study describes the clinical and epidemiological characteristics of quad bike injuries at the Royal Darwin Hospital (RDH).

METHODS

A retrospective review of the RDH Trauma Registry for all quad bike mechanism of injury from 1 January 2006 to 31 December 2015 was conducted. We analysed patient demographics, remoteness of injury, injury circumstances, patterns and severity of injury, surgical intervention, length of stay and outcome.

RESULTS

In total, 186 persons were injured, of whom 81% (n = 150) were male. There was an increase in quad bike incidents during the 10-year study period, and the greatest increase was seen in the 16-30 years age group. When helmet use was recorded, it was low at 36% (n = 47). Alcohol involvement was 40% (n = 74). Cases with alcohol involvement were 10 times less likely to have worn a helmet than those cases without alcohol involvement (95% confidence interval 3.8-29). The median Injury Severity Score was 8 (interquartile range 4-10). The median hospital length of hospital stay was 4 days (interquartile range 3-7). The majority, 57% (n = 106), did not require surgical intervention. The fatality rate was <5%.

CONCLUSION

Quad bike incidents presenting to RDH are increasing. This likely corresponds to the increased number of quad bikes in circulation, and has resulted in an increased demand on health care. Alcohol use and a lack of safety equipment continue to be potentially correctable factors.

Burn injury as a result of interpersonal violence in the Northern Territory Top End

AIM

To describe the demographics, circumstances, burn wound characteristics and current tertiary centre management of interpersonal violence (IPV) burn victims in the Northern Territory Top End. It is anticipated that such knowledge gained will be of benefit to key stakeholders across the spectrum of injury prevention and management in this region.

METHODS

All adult admissions to the Royal Darwin Hospital (RDH) during 2010-2015 were identified through the Burns Registry of Australia and New Zealand. Demographic and burn characteristics were compared between those classified as IPV and non-IPV. Case note review provided supplementary data for the IPV subset.

RESULTS

Fifty-three patients met IPV criteria, comprising 7.4% of admissions to the RDH Burn Service. IPV burn victims were 2.3 times more likely to be female than those with non-IPV burn (95% CI: 1.2-4.3), and 17 times more likely to be Indigenous (95% CI: 7.9-35). Approximately half (53%) of IPV burns were classified as family or domestic violence; scalding was the most common mechanism in this group. Ten patients (19%) had incomplete burn care through self-discharge, all identified as Indigenous. Twenty percent of patients had no documented inpatient psychosocial support.

CONCLUSIONS

Female and Indigenous persons are at increased risk of IPV burn. The challenges of providing care to the IPV burn population extend beyond burn wound closure.

Trauma-related admissions to intensive care units in Australia: the influence of Indigenous status on outcomes

OBJECTIVES

To investigate the admission characteristics and hospital outcomes for Indigenous and non-Indigenous patients admitted to intensive units (ICUs) after major trauma.

DESIGN, SETTING

Retrospective analysis of Australian and New Zealand Intensive Care Society (ANZICS) Adult Patient Database data from 92 Australian ICUs for the 6-year period, 2010-2015.

PARTICIPANTS

Patients older than 17 years of age admitted to public hospital ICUs with a primary diagnosis of trauma.

MAIN OUTCOME MEASURES

ICU and overall hospital lengths of stay, hospital discharge destination, and ICU and overall hospital mortality rates for Indigenous and non-Indigenous patients.

RESULTS

23 804 people were admitted to Australian public hospital ICUs after major trauma; 1754 (7.4%) were Indigenous Australians. The population-standardised incidence of admissions was consistently higher for Indigenous Australians than for non-Indigenous Australians (847 per million v 251 per million population; incidence ratio, 3.37; 95% CI, 3.19-3.57). Overall hospital mortality rates were similar for Indigenous and non-Indigenous patients (adjusted odds ratio [aOR], 1.04; 95% CI, 0.82-1.31). Indigenous patients were more likely than non-Indigenous patients to be discharged to another hospital (non-Indigenous v Indigenous: aOR, 0.84; 95% CI, 0.72-0.96) less likely to be discharged home (non-Indigenous v Indigenous: aOR, 1.17; 95% CI, 1.04-1.31).

CONCLUSION

The population rate of trauma-related ICU admissions was substantially higher for Indigenous than non-Indigenous patients, but hospital mortality rates after ICU admission were similar. Indigenous patients were more likely to be discharged to a another hospital and less likely to be discharged home than non-Indigenous patients.

The Transition from Hospital to Home: Protocol for a Longitudinal Study of Australian Aboriginal and Torres Strait Islander Traumatic Brain Injury (TBI)

Background: Traumatic brain injury (TBI) is a leading cause of disability in Australia. Evidence shows that multidisciplinary rehabilitation and support in the six months following TBI is important for successful independent living and social re-integration. Despite this, access to services and supports during this period is often limited by environmental, socio-economic, geographic and cultural factors. Australian studies on outcomes after brain injury have reported primarily on non-Indigenous people. This study will investigate key sentinel events during the transition from hospital to home after a TBI in the first longitudinal study with Indigenous Australians.

Method: Indigenous Australians admitted to one of three major trauma hospitals in northern Australia with a TBI, and their care givers, will be recruited. Clinical and brain injury risk factor information, along with measures of cognitive function, transition events, mental health and community re-integration will be collected at three time points prior to hospital discharge, and at three and six months post-discharge. Qualitative interviews will also be conducted. Data will be analysed using regression methods for the quantitative component, and situational analysis for the qualitative component. Annual rates of brain injury will be calculated for patients admitted to tertiary hospital facilities in the study region with a diagnosis of TBI.

Discussion: Understanding the experience and events which shape the transition period is critical to determining the services and supports that may enhance transition outcomes, and ensure that such services are culturally appropriate and endorsed by Indigenous families and communities.

Examining Injury Among Indigenous Young People: A Narrative Scoping Review

Indigenous young people of circumpolar developed countries experience a disproportionate incidence of injury compared with non-Indigenous young people. Much has been published about the experience of injury within the general Indigenous population, but literature is limited with regard to Indigenous young people. Trauma nurses, who are important members of the multidisciplinary team that provides injury intervention to Indigenous populations, need to be aware of this literature, as well as subsequent research gaps, to provide effective care to Indigenous young people experiencing injury. The purpose of this study was to provide an updated comprehensive review of the research-based evidence related to all-cause injury for Indigenous young people. An exploratory scoping review was conducted with a narrative synthesis. To locate literature, 7 electronic databases were searched from 2003 to 2017. Criteria were applied to all located articles to determine inclusion and then data were extracted from each study's findings. A total of 15 studies were included in this review that met the inclusion criteria. Themes derived from the knowledge synthesis process are as follows: incidence rates, mechanisms of injury, risk factors, and gaps in research. A strong epidemiological focus has emerged from the research found in this review of injury among Indigenous young people. The results of this review serve as a starting point for trauma nurses to successfully assess, build trusting relationships with, and further research injury among Indigenous young people.

Burns first aid treatment in remote Northern Australia

BACKGROUND AND OBJECTIVE

It is well demonstrated that adequate burns first aid treatment (BFAT) improves clinical outcomes for the injured but adequacy remains low in many studies. This study presents a twelve month assessment of the adequacy of burns first aid treatment for patients managed by the Burns Service, Royal Darwin Hospital (RDH).

METHODS

Prospective study design of all patients managed by the Burns Service, Royal Darwin Hospital. Data were collated from two sources; RDH Burns Registry, and the Burns Registry of Australia and New Zealand (BRANZ). Inclusion criterion was all patients managed by the Burns Service, Royal Darwin Hospital for the period 1 January 2014-31 December 2014. Variables collected and analysed include: demographics, burn mechanism, burn wound depth and adequacy of and circumstances around first aid.

RESULTS

Overall 310 cases were analysed. Most injuries involved adults (68%), 19% Indigenous persons and 70% of all patients had their burn injury occur in the urban region. Adequate BFAT occurred in 41% of cases. Adults, contact burns and those where the burn injury occurred in the remote regions were less likely to receive adequate BFAT. Indigenous persons were less likely to attempt any BFAT at all and when they did receive BFAT it was more likely applied by an emergency responder or health professional.

CONCLUSION

Overall adequacy of BFAT is low in the Top End of the Northern Territory. Remote dwellers and Indigenous persons are at increased risk of not applying or receiving adequate BFAT. The poor level of adequate BFAT demonstrated in this study suggests that the Top End community particularly remote and Indigenous persons would benefit from targeted BFAT education programs that are delivered in a culturally and linguistically appropriate fashion.

Epidemiology and Pattern of Traumatic Brain Injury in a Developing Country Regional Trauma Center

Objective

To determine the epidemiological aspects of patients with traumatic brain injury (TBI) in a regional trauma center.

Methods

A cross-sectional study was conducted on patients with TBI during 2013 to 2016 in a single center in Hamedan, central Iran. The distribution and relationships of TBI was assessed with gender, age, type of trauma, traumatic cause, exiting status and Length of Hospitalization (LOH). Data were analyzed by Stata V11 statistical software.

Results

In general, 9426 patients with TBI were enrolled in analyses. The mean ± SD age of patients was 29.70 (± 21.46) years. Multivariate logistic regression indicated that being male [OR: 1.29; 95% CI (2.92-4.73), P ≤0.001], 41-50 to 71-80 and 90+ years old' age groups (1.32<OR<3.12, 0.029<p≤0.001), having surgery [OR: 5.58; 95% CI (4.89-6.37), p≤0.001], and different types of trauma (p≤0.001) were significantly related to LOH. Moreover, odds ratio of mortality was 1.52 times greater in males than females (p≤0.001). As the age increases, the odds ratio of mortality was also rising. However, having surgery [OR: 3.72; 95% CI (2.92-4.73), p≤0.001], LOH >5 days [OR: 2.01; 95% CI (1.60-2.52), p≤0.001] and different types of trauma were significantly related to mortality.

Conclusion

TBI is one of the main causes of mortality and LOH of the young population. By providing preventive measures and a traumatic care system, the burden of trauma can be greatly reduced, the implementation of the trauma care system in Hamedan province is a necessity.

Characteristics of trauma mortality in the Northern Territory, Australia

BACKGROUND

While factors including remoteness, alcohol consumption, age and Indigenous ethnicity are well-documented associations of trauma mortality, less is known of trauma seasonality. This is particularly relevant to Australia's Northern Territory, with its tropical regions experiencing a climate of wet (hot and humid) and dry (warm) seasons annually. The aim of this study was to therefore, examine the characteristics of trauma mortality in the Top End, Northern Territory, Australia.

METHODS

A retrospective review of the National Coroners Information System (NCIS) database from 1 January 2003 to 31 December 2007 analysed four-hundred and sixteen traumatic deaths where the trauma event and death occurred within the Top End of the Northern Territory.

RESULTS

The annual traumatic death rate for the Top End was 58.7 per 100 000, with variance between regions (accessible 38.1; remote 119.1 per 100000, respectively). Overall alcohol was involved in 56.5% of cases. The three most frequent mechanisms of death were suicide, transport related and assault, accounting for 81.5% of deaths. These respective mechanisms of death demonstrated seasonal influence, with transport related deaths 2.5 times more likely to occur in the dry than the wet season (p < 0.001), while assault related deaths were 3.3 times more likely to occur during the wet season (p = 0.005), and suicide was 1.6 times more likely to occur during the wet season (p = 0.022). Transport related deaths were 2.2 times more likely in remote and very remote settings than in accessible or moderately accessible regions (p < 0.003), whereas death by suicide was less likely to occur in remote and very remote regions than in accessible or moderately accessible areas (p = 0.012).

CONCLUSION

Excessively high rates of traumatic death in the Top End of the Northern Territory were evident, with contrasting seasonal and regional profiles. Based upon the data of this investigation, existing programmes to minimise trauma in the Northern Territory ought to be evaluated for seasonal and regional specificity.

Patterns of paediatric emergency presentations to a tertiary referral centre in the Northern Territory

OBJECTIVE

To describe epidemiological data concerning paediatric attendances at the ED of Royal Darwin Hospital (RDH).

METHODS

We conducted a retrospective cohort study of paediatric emergency presentations to the RDH ED during 2004 and 2013. Epidemiological data, including demographics, admission rates and diagnostic grouping, were analysed using descriptive and comparative statistical methods. We compared data with findings from a baseline epidemiological study by the Paediatric Research in Emergency Departments International Collaborative (PREDICT) conducted in 2004.

RESULTS

A total of 12 745 and 15 378 paediatric presentations (age 0-18 years) to the RDH ED were analysed for the years 2004 and 2013 respectively. In 2004, the mean age of children presenting to RDH was 7.1 years, and 56.0% were female. Indigenous patients accounted for 31.2% of presentations at RDH and were significantly more likely to be admitted than non-Indigenous patients (31.6% vs 12.8%, OR 3.24, 95% CI 2.95-3.55). Children <5 years old accounted for the highest number of presentations (45.2%) and admissions (51.2%), and there was a high proportion of adolescent presentations (18.0%). Similar to the PREDICT study, viral infectious conditions (bronchiolitis, gastroenteritis, upper respiratory tract infections) were the most common cause for presentations. Key differences included a higher proportion of patients presenting with cellulitis and head injury at RDH and an increasing proportion of adolescent psychiatric presentations at RDH from 2004 to 2013.

CONCLUSION

This study provides important information regarding paediatric presentations to a major referral hospital in the Northern Territory. Overall, there was a disproportionate rate of presentation and admission among Indigenous children. Other key findings were higher proportions of cellulitis, head injury and adolescent presentations. These findings can assist in service planning and in directing future research specific to children in the Northern Territory.
