The question of fluid volume in resuscitation has been identified as the top priority in sepsis research by emergency physicians in the United Kingdom, Australia and New Zealand. Guidelines and sepsis pathways recommend an initial intravenous (IV) fluid bolus of 30ml/kg isotonic crystalloid for patients with sepsis and hypotension. However, there is a lack of evidence from clinical trials to support this strategy. Both observational data as well as randomised studies suggest there may be harm associated with injudicious use of fluids in sepsis. Since there is equipoise regarding a more liberal or restricted fluid volume resuscitation as first line treatment for sepsis-related hypotension, we conducted the pilot multicentre REstricted Fluid REsuscitation in Sepsis-associated Hypotension (REFRESH) trial comparing a restricted fluid protocol with early initiation of vasopressor support against standard guideline care.
The data from REFRESH will inform feasibility of a large, multicentre phase III study. However, further ground work is essential for the optimal design of a Phase III trial that will provide valuable information on feasibility (road test recruitment rate and screening processes) as well as refinement of the protocol (sample size estimation, processes of care, prevalence of the population of interest, real world clinical practice regarding fluid use).
In this ARISE Fluids study, we aim to provide more insight into current practice by conducting a bi-national multi-site prospective observational study of fluid administration in (suspected) sepsis and hypotension in the Emergency Departments of Australia and New Zealand hospitals. Sites have been selected on the basis of having expressed interest in participating in a phase III trial.READ MORE
This study will collect information from the records of 3000 children from 30 hospitals presenting after a head injury in 2016 and will interview staff to look at different factors influencing the care provided. APHIRST-Gap is expected to provide crucial information on scan rates and inform strategies, including national guideline development to standardise and improve the care of children with head injury across Australia and New Zealand.
Head injury is a common reason children present to Emergency Departments in Australia and New Zealand. While most are minor the important issue for emergency clinicians is to determine whether a particular child is at risk of a serious head injury such as a bleed on the brain. A computerised tomography(CT) scan is the investigation of choice to look for these injuries. Its presents risks though, including the risk of sedation, and radiation induced cancer.
Several “rules” have been designed to guide doctors in the decision, by weighing up the risk of injury with the risks associated with the scan. The published Australasian APHIRST study examined three of these rules. It found that all three rules performed well, clinicians made sound judgements, and the overall rate of CT scan use was low (10%). APHIRST was limited to 10 large metropolitan, and predominately paediatric hospitals. Most children in Australia are not seen in these hospitals. Further research is required to determine whether there is a large variation in scan use between different hospitals and how best to apply these findings to a broader range of hospitals.
This trial is being run by the PREDICT network and the Principal Investigator is Prof Franz Babl.READ MORE
Shortness of breath (dyspnoea) is a terrifying symptom experienced by patients and is a common reason for presentation to Emergency Departments. There are a wide range of causes including flair up due to chronic conditions such as asthma, heart failure, chronic lung disease or liver or kidney failure. Acute conditions such as a collapsed lung, chest infection (including pneumonia), trauma (including fractured ribs), airway blockage or an allergic reaction can also be the cause.
There is significant knowledge about patients who are admitted to hospital with common causes, however there is little conclusive information about Dyspnoea as a symptom, the distribution of causes, the proportion of patients requiring admission and whether treatment complies with evidence-based guidelines.
A recent pilot study in Europe found that 53 per cent of patients had a respiratory cause for symptoms, 22 per cent had a cardiac cause, and 15 per cent had both cardiac and respiratory components. Almost two-thirds were admitted to hospital with over one-third discharged from ED. However, in many ways, the study raised more questions than it answered. The study was also too small to comment on adherence to evidence-based guidelines.
For that reason, a larger EuroDEM (digital elevation model) study is planned for 2014. The study will be complemented by the Australia, Asia and New Zealand Dyspnoea Departments of Emergency Medicine (AANZDEM) which will collect data from a different region with different systems of care. It will focus on the range of causes, variation over seasons and geographical areas, and compliance with recommended treatments.READ MORE
Gastrointestinal (GI) bleeding is a common emergency with a substantial mortality rate. Bleeding from the upper gastrointestinal system is caused by ulcers, stomach inflammation and oesophageal varices and carries a fatality rate of up to 10%. Lower GI bleeding has a variety of causes and a case fatality of about 15%. Between 10% and 25% of patients will have a repeat bleed after their first episode, and these people are four times more likely to die than people without repeated bleeding.
The clotting of blood helps to stem bleeding and blood clot break down may play an important role in GI bleeding and re-bleeding. Tranexamic acid (TXA) is a drug used to reduce clot breakdown. It has been shown to reduce the probability of requiring a blood transfusion by about a third in surgical patients, without causing serious side effects from promoting clotting. This high quality randomised controlled trial will investigate the effectiveness and safety of TXA in GI bleeding.READ MORE
The increasing demand on emergency health care in Australia has seen recent emphasis on clinical redesign initiatives that are focused on time-based performance measures and activity-based funding. While congestion in emergency departments continues, and emphasis is placed on reaching these time targets, the quality of care that patients receive when presenting with non-life threatening injuries is potentially compromised.
To date, there is a lack of high-level evidence surrounding the type of quality indicators (QIs) that should be used in EDs to measure quality of care. This project will develop QIs for care of patients who present to EDs with musculoskeletal injuries under appropriate expert review. The final QI set will allow application across EDs and will contribute to comparison and optimisation of emergency care for patients in ED with musculoskeletal injuries.READ MORE
Primary spontaneous pneumothorax (PSP) is defined as a collapsed lung with air in the pleural cavity that occurs in the absence of clinically apparent underlying lung disease. PSP is a significant global health problem affecting adolescents and young adults. Throughout the 20th century the treatment of PSP was predominantly bed rest, with invasive treatment reserved for severely symptomatic episodes. A study in 1966 suggested that managing large and small PSP in the community was safe. Despite this, rates of intervention have steadily increased over the decades. The reasons for this are unclear and this approach has recently been questioned in the scientific literature. Preliminary data suggests that a conservative approach to management may allow faster healing and reduce the risk of recurrence from around 25 per cent to 5 per cent in the first year. Conservative management is also likely to reduce the risks of prolonged admission due to persistent leak from approximately 30 per cent to less than 10 per cent and of other complications related to interventional management. Clinicians are, however, unlikely to change a practice entrenched for decades and re-enforced by current international guidelines without robust evidence.
This study will significantly increase our understanding of Primary spontaneous pneumothorax and its optimal management. If allowing the lung to remain collapsed initially results in improved healing of the pleural defect and lower recurrence rates then this study will contribute to improve outcomes and a reduction in the morbidity associated with current treatment.READ MORE
The World Health Organization reports that trauma will be the major contributor to the 49.7 million annual deaths globally from non–communicable disease in 2020. Trauma and sepsis are the two leading causes of death worldwide. This project aims to examine the effects of trauma and severe infection on oxygen supply to various tissues and organs.
We will study what infection does to metabolism and the degree of inflammation in these tissues. The effects of resuscitation on these tissue parameters while using stored and fresh blood will also be studied.
The aims of this research are to link best practice ED workforce models to available ED funding under an activity-based funding (ABF), while contributing to the development of an improved national activity and outcome-based ED funding model. This research will identify the current status of funding of EDs, identify and critically appraise models for funding of EDs and identify the workforce implications of those funding models and propose a State-wide ED clinical workforce framework.READ MORE
