Trauma care in the tropics: addressing gaps in treating injury in rural and remote Australia.

In Australia, over half a million people are admitted to hospital every year as a result of injury, and where you live matters. Rural populations have disproportionately higher injury hospitalisation rates (1.5-2.5-fold), higher rates of preventable secondary complications, higher mortality rates (up to fivefold), and higher costs (threefold) than patients injured in major cities. These disparities scale up rapidly with increased remoteness, and shift the service needle from 'scoop and run' to 'continuum of care'. Poorer outcomes, however, are not solely due to longer retrieval distances or delays; they arise from inefficiencies in one or more potentially modifiable factors in the chain of survival. After discussing the burden of injury in Australia, we present a brief history of retrieval services in Queensland and discuss how remoteness requires a different kind of service delivery with many moving parts from point of injury to definitive care. We next address the ongoing challenges for the Australian Trauma Registry, and how centralisation of data from the metropolitan cities masks the inequities in rural and remote trauma. There is an urgent need for accurate data from all service providers around Australia to inform state and federal governments, and we highlight the paucity of trauma data analysis in North Queensland. Last, we identify some major gaps in treating rural and remote polytrauma and en-route patient stabilisation, and discuss the relevance of combat casualty care research and practices. We conclude that a greater emphasis should be placed on collecting more robust trauma patient records, as only accurate data will drive change.

Aeromedical retrievals in Queensland: A five-year review.

OBJECTIVE: Aeromedical services are an essential part of the healthcare system. Centralised coordination of aeromedical retrieval tasking offers benefits for safety, timeliness and efficiency in service delivery. The aim of the present study is to review aeromedical retrievals in Queensland exploring patient demographics, temporal patterns and usage characteristics. METHODS: This is a retrospective cases series for the period 1 January 2010 to 31 December 2014 incorporating data from Retrieval Services Queensland and Queensland Newborn Emergency Transport Service. Ethics approval was obtained (JCU-HREC H6137 and Public Health Act #RD005673). Descriptive analysis of the de-identified data was undertaken included patient demographics, referral and receiving locations, retrieval platform and acuity of transport request. RESULTS: There were 73 042 aeromedical retrievals undertaken during the period, with an average of 40 cases per day (range 16-89). The majority (95%) of retrievals were for Queensland residents. Overall 23.1% of cases were cardiology-related and 12.7% were injury-related. Older adults aged 75-84 years had the highest rate of retrievals relative to the population with a crude rate of 942.4 per 100 000 per annum. Overall 14.9% of cases were Priority 1, which represents the tasking with the highest acuity but majority were Priority 4 (41.6%). One third (37.6%) of all patients were from inner regional locations. CONCLUSIONS: Potential investments in health service planning may alleviate the burden on aeromedical services, particularly related to cardiology services in inner and outer regional Queensland. Aeromedical services are pivotal in enabling all sick and injured residents' access to the highest quality of care regardless of the remoteness of their residence.

Review article: Primary aeromedical retrievals in Australia: An interrogation and search for context.

Primary aeromedical retrievals are a direct scene response to patients with a critical injury or illness using a medically equipped aircraft. They are often high-acuity taskings. In Australia, information on primary retrieval taskings is housed by service providers, of which there are many across the country. This exploratory literature review aims to explore the contemporary peer-reviewed literature on primary aeromedical retrievals in Australia. The focus is on adult primary aeromedical retrievals undertaken in Australia and clinical tools used in this pre-hospital setting. Included articles were reviewed for research theme (clinical and equipment, systems and/or outcomes), data coverage and appraisal of the evidence. Of the 37 articles included, majority explored helicopter retrievals (n = 32), retrieval systems (n = 21), compared outcomes within a service (n = 10) and explored retrievals in the state of New South Wales (n = 19). Major topics of focus included retrieval of trauma patients and airway management. Overall, the publications had a lower strength of evidence because of the preponderance of cross-sectional and case-study methodology. This review provides some preliminary but piecemeal insight into primary retrievals in Australia through a localised systems lens. However, there are several areas for research action and service outcome improvements suggested, all of which would be facilitated through the creation of a national pre-hospital and retrieval registry. The creation of a registry would enable consideration of the frequency and context of retrievals, comparison across services, more sophisticated data interrogation. Most importantly, it can lead to service and pre-hospital and retrieval system strengthening.

Local morbidity from red-bellied black snake (Pseudechis porphyriacus, Elapidae) envenoming: Two cases and a brief review of management.

The red-bellied black snake (Pseudechis porphyriacus, Elapidae) is one of several species of venomous snakes most commonly implicated in human and domestic animal envenoming in Australia. Human systemic envenoming can present with myotoxicity that may include myoglobinuria; hemoglobinuria and intravascular hemolysis; thrombocytopenia, anticoagulant coagulopathy, and, rarely, mild cranial nerve palsies. Pseudechis porphyriacus envenoming can also feature significant local morbidity such as ecchymoses, bleeding, pain and necrosis. Some envenomed patients may develop progressive thickness necrosis independent of secondary infection, and occasionally require surgical debridement. Uncommonly, some digital envenoming may cause more severe deeper tissue pathology that justifies dermotomy and/or distal phalangeal amputation. Presented are two patients with significant local morbidity from P. porphyriacus envenoming. An 18-month old girl received a protracted envenoming on her right foot, while a 38-year old male professional zoologist was envenomed on the third digit of his right hand. Each patient experienced myotoxicity, one had anticoagulant coagulopathy, and both developed clinically significant local morbidity including persistent bleeding, ecchymoses, local necrosis and pain; each required extensive treatment and variably prolonged admission. Noted also were transiently elevated D-dimer with low-normal or normal fibrinogen levels. The progressive necrosis and subsequent chronic pathologic changes with ischemia of the latter patient's digit eventually required a dermotomy and amputation of the distal phalanx. The pediatric patient did not require extensive wound debridement, but experienced prolonged difficulty in ambulation because of slowly resolving wound discomfort. Factors that may contribute to the severity of local morbidity of P. porphyriacus envenoming are considered, and management of envenoming by this taxon is briefly reviewed.

Informed consent in emergency care research: An oxymoron?

Emergency care needs to be underpinned by the highest quality evidence. However, research involving critically ill patients in the emergency setting has unique ethical, logistical and regulatory issues. Informed consent is a well-established principle in conventional research. In this article, we discuss informed consent as it pertains to the difficulties of research in the emergency setting. Alternatives to informed consent are discussed. Human research ethics committees require a greater understanding of consent issues in emergency care research for Australia to remain competitive internationally.

Don't Blow It! Extensive Subcutaneous Emphysema of the Neck Caused by Isolated Facial Injuries: A Case Report and Review of the Literature.

BACKGROUND: Although subcutaneous emphysema resulting from maxillofacial surgery is well described in the literature, the association with maxillofacial trauma is less firm. Clinically evident subcutaneous emphysema from facial injury is uncommon and extension into the cervical and mediastinal tissues is exceedingly rare, with few reported cases. CASE REPORT: An unusual case of extensive subcutaneous emphysema after facial trauma is presented. The case posed a diagnostic dilemma in our emergency department. WHY SHOULD EMERGENCY PHYSICIANS BE AWARE OF THIS?: Facial fractures are a rare but important cause of surgical emphysema. Emergency physicians need to be aware of the diagnostic possibility and the need to avoid factors that may precipitate secondary injury.

Trends in access block 2011 to 2013: the Redcliffe National Emergency Access Target experience.

OBJECTIVE: To evaluate the impact of the introduction of National Emergency Access Target (NEAT) on access block and long-stay patients in Redcliffe Hospital ED, and to evaluate the possibility of forward compliance with the 2014 and 2015 NEAT thresholds. SETTING AND DESIGN: Redcliffe hospital is a major urban district hospital in Brisbane with more than 55,000 adult and paediatric patients per annum. We evaluated aggregate Emergency Department Information System data for the years 2011, 2012 and 2013 to correlate presentations, NEAT compliance, access block and the number of long-stay patients in our department. RESULTS: There has been a significant reduction in both access block and our number of long-stay patients corresponding with improvements in NEAT compliance. Our forward analysis suggests that without substantial improvements in the NEAT for admitted patients, compliance with 2014 and 2015 thresholds is unlikely to be achievable. CONCLUSIONS: NEAT has been a driver of significant improvements in access block at our institution. We see significant issues with raising the NEAT threshold to the proposed 90% in 2015, and support recent calls for re-evaluation and modification of the target.

The utility of Advanced Trauma Life Support (ATLS) clinical shock grading in assessment of trauma.

BACKGROUND: Acute haemorrhage is a major contributor to trauma related morbidity and mortality. Quantifying blood loss acutely and accurately is a difficult task and no currently accepted standard exists. We introduce a simple shock grading tool incorporating vital signs, fluid response and estimated blood loss to describe shock grade during the primary survey based on the original Advanced Trauma Life Support (ATLS) classification. METHODS: We performed a prospective cohort study of all trauma patients admitted to our emergency room over a 1-year period to evaluate the utility of this tool for emergency physicians to detect significant haemorrhage in the trauma patient. Shock grades were prospectively assigned to patients by the trauma team as part of the primary survey, and followed up to assess for outcomes. The primary outcome was a composite endpoint of clinical, radiological and operative findings consistent with significant haemorrhage. Data were analysed using linear and logistic regression to assess predictive ability and receiver operator characteristic curve to assess overall diagnostic accuracy. RESULTS: The overall sensitivity of the shock grading tool was 83%. The diagnostic accuracy based on area under receiver operator characteristic curve was 0.86. There was also a significant association between increasing shock grade and both injury severity score (ß coefficient 7.0, p<0.001, 95% CI 6.2 to 7.8) and the presence of significant haemorrhage (OR 5.1, p<0.001, 95% CI 3.6 to 7.3). CONCLUSIONS: We conclude that a simple ATLS based clinical tool that objectively categorises haemorrhagic shock is a useful part of the primary survey of the trauma patient, although a larger study with higher statistical power is required to evaluate this conclusion further.

Public health and crisis leadership in the 21st century.

Public health crises are becoming increasingly complex, and as such leaders need to revisit their roles and consider new problems arising for public health today. Dr Luke Lawton, of Redcliffe Hospital in Queensland, Australia examines the nature of leadership and provides some pointers on crisis planning.

Chronic malnutrition may in fact be an acute emergency.

BACKGROUND: Reintroduction of nutrition to the chronically starved patient presents a constellation of metabolic challenges termed "refeeding syndrome." The consequences of this syndrome--principally hypophosphatemia--may be life threatening. Although previously described in the nutritional literature, little information exists on this syndrome written from the perspective of the emergency physician. OBJECTIVES: To promote the early use of prophylactic electrolyte replacement in patients at risk of refeeding syndrome. CASE REPORT: We present the case of a 32-year-old woman with self-inflicted starvation who developed severe hypophosphatemia, hypocalcemia, and hypomagnesemia due to unintended refeeding in the emergency department (ED). CONCLUSIONS: The acute complications of refeeding syndrome may present during a patient's stay in the ED or during the transition from the ED to a critical care area, and thus this syndrome deserves consideration from the moment a starved patient presents to our triage desks.
