Comparison and outcomes of emergency department presentations with respiratory disorders among Australian indigenous and non-indigenous patients.

BACKGROUND: There is sparse evidence in the literature assessing emergency department presentation with respiratory disorders among Indigenous patients. The objective of this study was to evaluate the clinical characteristics and outcomes for Indigenous Australians in comparison to non-Indigenous patients presenting to Emergency Department (ED) with respiratory disorders. METHODS: In this study, two non-contiguous one-month study periods during wet (January) and dry (August) season were reported on, and differences in demographics, respiratory diagnosis, hospital admission, length of hospital stay, re-presentation to hospital after discharge and mortality between Australian Indigenous and non-Indigenous patients was assessed. RESULTS: There were a total of 528 respiratory ED presentations, 258 (49%) during wet and 270 (51%) in dry season, from 477 patients (52% female and 40% Indigenous). The majority of ED presentations (84%) were self-initiated, with a difference between Indigenous (80%) and non-Indigenous (88%) presentations. Indigenous presentations recorded a greater proportion of transfers from another healthcare facility compared to non-Indigenous presentations (11% vs. 1%). Less than half of presentations (42%) resulted in admission to the ward with no difference by Indigenous status. Lower respiratory tract infections were the most common cause of presentation (41%), followed by airway exacerbation (31%) which was more commonly seen among Indigenous (34%) than non-Indigenous (28%) presentations. Almost 20% of Indigenous patients reported multiple presentations to ED compared to 1% of non-Indigenous patients, though mortality on follow up did not differ (22% for both). CONCLUSIONS: The results of this study may be an avenue to explore possibilities of implementing programs that may be helpful to reduce preventable ED presentation and recurrent hospitalisations among Indigenous population.

Hot water immersion v icepacks for treating the pain of Chironex fleckeri stings: a randomised controlled trial.

OBJECTIVE: To investigate the effectiveness of hot water immersion for relieving the pain of major box jellyfish (Chironex fleckeri) stings.Design, interventions: Open label, randomised controlled trial comparing the effects of hot water immersion (45°C) and icepacks.Setting, participants: 42 patients with suspected C. fleckeri stings treated in the emergency department of the Royal Darwin Hospital during September 2005 - October 2008. MAIN OUTCOME MEASURES: The primary outcome was pain severity, assessed with a visual analogue scale (VAS). Secondary outcomes included crossover to the alternative treatment, use of opioid analgesia, emergency department length of stay (LOS), and delayed urticaria. RESULTS: Of 42 patients (26 males; median age, 19 years; IQR, 13-27 years), 25 were allocated to icepack treatment and 17 to hot water immersion. The demographic and baseline VAS data for the two groups were similar. After 30 minutes of treatment, 11 patients (65%) treated with hot water and 14 (56%) treated with icepacks had clinically improved pain scores (absolute difference, 9%; 95% CI, -22% to 39%; P = 0.75). One patient treated with icepacks crossed over to heat immersion. Two patients in each arm received intravenous opioid analgesia. Median emergency department LOS was 1.6 h (IQR, 1.0-1.8 h) for icepack patients and 2.1 h (IQR, 1.6-2.8 h) for heat immersion patients (P = 0.07). Five of seven patients who were followed up developed delayed urticaria. CONCLUSION: Hot water immersion was no more effective than icepacks for reducing the acute pain of box jellyfish stings, but increased emergency department LOS by about 30 minutes.

Use of Royal Darwin Hospital emergency department by immigration detainees in 2011.

OBJECTIVE: To describe the number and nature of emergency department (ED) attendances by immigration detainees in Darwin, in the Northern Territory, over a 12-month period. DESIGN AND SETTING: Retrospective observational study of immigration detainees attending the Royal Darwin Hospital ED during the 2011 calendar year. MAIN OUTCOME MEASURES: Number of ED attendances and primary diagnoses. RESULTS: In 2011, there were 770 ED attendances by 518 individual detainees at Royal Darwin Hospital. Those who attended the ED had a mean (SD) age of 27.6 (12.2) years, and 112 of them (21.6%) were children. Most (413, 79.7%) were male, and Iran and Afghanistan were the two most common countries of birth. We estimate that 50.1% (95% CI, 47.0%-53.2%) of immigration detainees in Darwin (mean, 776 per month; total, 1034), attended the Royal Darwin Hospital ED at least once in 2011. The most common primary diagnosis was psychiatric problems (187 attendances, 24.3%), including self-harm (138 attendances, 17.9%). CONCLUSION: In 2011, asylum seekers in immigration detention in Darwin had a high prevalence of unmet health needs and substantial levels of psychiatric morbidity. The primary health care provided to them was inadequate.

Prevention of Alcohol-Related Crime and Trauma (PACT): brief interventions in routine care pathway - a study protocol.

BACKGROUND: Globally, alcohol-related injuries cause millions of deaths and huge economic loss each year . The incidence of facial (jawbone) fractures in the Northern Territory of Australia is second only to Greenland, due to a strong involvement of alcohol in its aetiology, and high levels of alcohol consumption. The highest incidences of alcohol-related trauma in the Territory are observed amongst patients in the Maxillofacial Surgery Unit of the Royal Darwin Hospital. Accordingly, this project aims to introduce screening and brief interventions into this unit, with the aims of changing health service provider practice, improving access to care, and improving patient outcomes. METHODS: Establishment of Project Governance: The project governance team includes a project manager, project leader, an Indigenous Reference Group (IRG) and an Expert Reference Group (ERG).Development of a best practice pathway: PACT project researchers collaborate with clinical staff to develop a best practice pathway suited to the setting of the surgical unit. The pathway provides clear guidelines for screening, assessment, intervention and referral. IMPLEMENTATION: The developed pathway is introduced to the unit through staff training workshops and associate resources and adapted in response to staff feedback. EVALUATION: File audits, post workshop questionnaires and semi-structured interviews are administered. DISCUSSION: This project allows direct transfer of research findings into clinical practice and can inform future hospital-based injury prevention strategies.

Impact of alcohol policy changes on substance-affected patients attending an emergency department in the Northern Territory with police.

OBJECTIVE: Assess the impact of Northern Territory alcohol policy changes to ED utilisation at Royal Darwin-Palmerston Regional Hospitals. METHODS: Interrupted time series analysis explored trends in monthly ED attendance numbers and the proportion self-discharging prior to policy changes (September 2016 to August 2017) and after three sequential interventions; the Banned Drinker Register, introduced September 2017, system changes to the sobering shelter, January 2018, and the minimum unit floor price (MUFP), October 2018. A targeted cohort of attendances transported by police as an alternative to the sobering shelter or police watch-house when there is a medical concern was selected as they are likely impacted by all policy changes. RESULTS: Police transported 1176 patients on 2070 occasions from September 2016 to March 2019. There was a downward trend in monthly attendances across the study period, with no significant change attributable to the Banned Drinker Register, a significant step decrease with the sobering shelter changes (P = 0.002), and a significant gradual decrease following the MUFP (P = 0.025). This represented an immediate decrease of 3.82 attendances per month/10 000 residents following the sobering shelter changes and a gradual decrease of 0.92 attendances/10 000 residents after the MUFP. Rates of self-discharge were high, 45% in the pre-intervention phase, decreasing to 28% following the MUFP but this trend did not reach significance with any intervention. CONCLUSION: The sequential introduction of broad sweeping alcohol policy changes introduced by the Northern Territory government was associated with significant reductions in ED utilisation. The proximity of the introduction of interventions creates difficulties identifying individual policy influence.

The SMART-COP score performs well for pneumonia risk stratification in Australia's Tropical Northern Territory: a prospective cohort study.

OBJECTIVE: To prospectively compare a modified pneumonia severity scoring system, SMARTACOP, with other severity scores in patients presenting with pneumonia to the emergency department (ED) of a tertiary referral hospital in tropical Australia. METHODS: We conducted a prospective observational study of adult patients presenting with radiologically confirmed pneumonia over a 12-month period. The sensitivity of risk stratification scores were assessed against the need for intensive respiratory or vasopressor support (IRVS). RESULTS: There were 367 ED attendances for pneumonia of whom 77.1% were admitted to hospital, 10% required intensive respiratory or vasopressor support and 2.8% died. Mean age was 50.0 years, 52% were men and 59% were Indigenous. The sensitivity of a SMART-COP score ≥3, a SMARTACOP score ≥3 and a pneumonia severity index (PSI) class ≥3 for predicting IRVS was 97%, 97% and 78% respectively. CONCLUSIONS: We found no significant advantage of the SMARTACOP over the SMART-COP score for the prediction of intensive respiratory or vasopressor support, but both scores significantly outperformed PSI. The SMART-COP score should replace the PSI in tropical Australia and should be assessed in other tropical areas for pneumonia risk stratification in emergency departments.

Safer coalmines, happier, healthier and more engaged canaries.

Addressing and limiting burnout and its significant impacts on emergency physicians is an important and ongoing challenge, requiring much more than a focus on individual resilience. This is a key understanding which guides and informs the Australasian College for Emergency Medicine's holistic approach and advocacy efforts when it comes to the wellness of emergency physicians and the health systems in which they operate.

Clinical risk for substance-affected patients attending an emergency department in the Northern Territory with police: A quality improvement initiative.

OBJECTIVE: Determine clinical risk for patients presenting to Royal Darwin Hospital ED when they cannot be cared for at the police watch-house (WH) or sobering-up-shelter (SUS) because of a medical concern. METHODS: This is a retrospective cohort study of police arrivals from May to July 2016. Data collection included demographics and presumed cause of intoxication. Outcomes used as markers of risk were departure status, return visit within 24 h and frequency of ED attendance over 3 months. Social determinants of poor health were collected for the June cohort. RESULTS: There were 247 attendances with police by 170 patients. Most were alcohol affected (monthly rates between 83% and 92%). The 'did not wait/left at own risk' rate was high (41-44% vs 7.7%; P < 0.001) and hospital admission rates low (2-7% vs 29%; P < 0.001). Rates of representation (20% within 24 h), ED attendance (≥73% had a further visit within 3 months), comorbidities (46% with three or more chronic diseases), homelessness (66%) and alcohol dependence (85%) were high. Patients presenting more than five times over 3 months were less likely to wait (odds ratio 2.4, 95% confidence interval 1.1-5.2, P = 0.03). CONCLUSION: This is a common presentation at Royal Darwin Hospital ED by a patient group with high levels of comorbidity, homelessness and alcohol dependence. Nearly half self-discharged prior to medical assessment. These patients frequently re-attend the same facilities and enter into a cycle of non-intervention. Case management across services is needed to improve the opportunity that these patients receive appropriate medical, social and addiction interventions.

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.

Demographic patterns of emergency presentations to Northern Territory public hospitals.

This study investigates demographic patterns of emergency presentations to Northern Territory (NT) public hospitals over the past five years with respect to population changes, Aboriginality and age of patients. Retrospective analysis was undertaken on the 1996-2001 data extracted from the NT Module of Caresys and the Hospital Morbidity Data System. There was a 4.6% decrease in total presentations to the five public hospitals but a 9.4% growth in the population during the study period. Substantial differences in emergency presentation patterns were found between Aboriginal and non-Aboriginal patients. There were more Aboriginal presentations than non-Aboriginal presentations for all age groups except for 5 to 19 years and 70 to 74 years. Analysis based on the national triage scale showed the higher needs of older adults with the 60 or over age group accounting for the majority of presentations, and Aboriginal presentation rates exceeded the non-Aboriginal presentation rates in most triage categories. Re-attendance within seven days at the emergency departments occurred predominantly among Aboriginal patients regardless of age group. The analysis has highlighted several emerging demographic patterns. The issue of non-urgent visits by Aboriginal patients occupying a large portion of the emergency department utilisation also needs to be addressed.

Emergency presentations to Northern Territory public hospitals: demand and access analysis.

This study aims to quantify trends in emergency presentations to Northern Territory (NT) public hospitals over the past five years with respect to demand and access. Retrospective analysis was undertaken on data extracted from the NT Module of Caresys and the Hospital Morbidity Data System. There has been a 4.6% decrease in presentations to the five public hospitals between 1996 and 2001 compared to a 9.4% growth in the population. Despite the apparent decline in total presentations, the acuity of patients has increased dramatically over the same period. Access analysis of presentations seen within the recommended triage time revealed considerable variability, especially for triage categories 2, 3 and 4. The access block problem, discrepancies in recorded waiting time and irregularities among the regional hospitals within the triage system have also been identified. Recommendations including improved access to inpatient beds and admission to wards were developed in response to the changing role of the emergency department.

Community-acquired bacteremic Acinetobacter pneumonia in tropical Australia is caused by diverse strains of Acinetobacter baumannii, with carriage in the throat in at-risk groups.

Acinetobacter isolates from eight subjects with community-acquired Acinetobacter pneumonia (CAAP), a major cause of fatal community-acquired pneumonia in tropical Australia, were phenotypically and genotypically confirmed by pulsed-field gel electrophoresis analysis to be broadly diverse Acinetobacter baumannii strains. Wet-season throat carriage of A. baumannii was found in 10% of community residents with excess levels of alcohol consumption, the major at-risk group for CAAP.

The Bali bombing: the Royal Darwin Hospital response.

After the Bali bombing on 12 October 2002, injured Australians were evacuated to Darwin. The first patients arrived at the Royal Darwin Hospital (RDH) 26 hours after the blasts. RDH assessed and resuscitated 61 patients (including 20 intensive care patients, with 15 requiring ventilation, 19 surgery and more than 20 escharotomies). RDH evacuated 48 patients to burns centres around Australia within 36 hours of the first patient arrivals at the hospital and 62 hours after the bomb blasts. The response was successful, but improvements are needed in coordination between the different groups involved in such operations.
