Coronary Artery Disease in Aboriginal and Torres Strait Islander People

Aboriginal and Torres Strait Islander people die from heart attacks at younger ages than non-indigenous Australians. The factors that increase risk of death from heart attack in young Aboriginal and Torres Strait Islander people are unknown.

Most patients who present to an Emergency Department (ED) with chest pain do not have a heart problem but all are assessed for their risk of having a life-threatening cause, such as heart attack. The level of risk determines which tests are performed so that a final diagnosis can be obtained as quickly as possible. Due to the lack of knowledge about risk factors in the Aboriginal and Torres Strait Islander population there is uncertainty about how best to use chest pain risk assessments in indigenous patients.

In this study, we will determine the rate of coronary artery disease (a hardening of arteries and the underlying cause of heart attacks) in Aboriginal and Torres Strait Islander people who present to the ED with chest pain. We will also compare the characteristics of patients who do and do not have heart attacks to identify potential risk factors for heart attack in this population.

The findings from this study will: 1) allow ED doctors to determine a baseline level of risk of heart attack for the Aboriginal and Torres Strait Islander patient population, and 2) provide preliminary information necessary for the design of large-scale research studies with the goal of determining specific risk factors for heart attack in Aboriginal and Torres Strait Islander people.

Better ways of pain management in adults with hip fractures

Hip fractures are extremely painful yet medications which are usually used to manage the pain can have significant complications, particularly in frail individuals. Numbing medications injected into the groin on the side of the hip fracture have been shown to decrease pain, confusion and chest infections in patients with hip fracture awaiting an operation.

It is usual for most patients presenting to emergency departments with a hip fracture to get a single injection of numbing medication. What isn’t known is whether multiple regular doses of numbing medications injected regularly via a plastic tube in the groin are more effective than a single injection in managing the pain of hip fractures.
The purpose of this study is to show multiple regular doses of numbing medications are better than a single injection. This will be achieved by examining the difference in the amount of pain, the quantity of pain medications, and the degree of confusion between the patients getting multiple doses and those getting a single injection.

This study will be the first of its kind to be done in an emergency department and is also unique in that it will involve patients with dementia who make up more than a third of patients with hip fracture and are usually excluded from studies. The study is expected to help manage the pain of the 1.6 million hip fracture patients worldwide and give emergency doctors an additional option of managing hip fracture pain.

Using bedside ultrasound to diagnose forearm fractures in children

This is a multicentre, open-labelled diagnostic randomised controlled trial to comparing the use of portable ultrasound and x-ray imaging to diagnose a buckle fracture in children. The trial will determine if there are differences in functional outcomes, patient and care-giver preferences, and health system benefits.

Children frequently present to the emergency department with forearm injuries and often have an x-ray to assess if there is a fracture. Due to the soft and plastic nature of the bones in young children, injuries can cause their bones to bend, known as a buckle fracture. Bedside ultrasound is a test that emergency practitioners can use to rapidly diagnose a fracture at the time of examination, without exposing children to ionising radiation. Ultrasound in this setting is well tolerated, only requiring light touch and gentle manipulation of the forearm and has similar accuracy when compared with x-rays for diagnosing children’s forearm fractures.

This is the first trial of its kind to assess whether an x-ray is unnecessary when there is either a buckle fracture or no fracture seen on a portable ultrasound machine. This is important as they can be treated at the time of review without any further delay, which will avoid these children being exposed to ionising radiation. Children will be randomised to receive either an ultrasound or x-ray for their forearm injury. Both groups will be followed up to see whether there are any differences in their recovery and to determine any complications. We will also determine the time and cost implications of this new approach, which could enable families to go home earlier and could be more cost-effective, with less x-rays being ordered.

Providing a safe and efficient method of chest pain assessment

In this project we will evaluate a new pathway for assessing chest pain in the emergency department. The pathway is designed to reduce the costs of managing patients at low-risk of heart attack without compromising patient safety. The cost savings are estimated to be around $95 million if implemented Australia-wide, with the bulk of the cost reduction being through decreased length of stay in the emergency department.

The new pathway will be implemented at three Queensland hospitals. Data collected before and after the implementation of this pathway will be used to assess 1) whether it results in a shorter length of stay in hospital, 2) whether it is safe for identifying heart attack, and 3) whether it reduces healthcare utilisation and healthcare costs.
Over 450,000 patients present to an Australian emergency department with chest pain every year. The current approach to rule out heart attack for these patients is lengthy and costly, taking up to 26 hours at a cost of $2,127 per patient.

Can assessment of parental concern improve sepsis recognition in children?

Sepsis is devastating infection, leading to organ dysfunction. Sepsis kills more children in Australia than road traffic accidents. One out of three survivors will suffer from long-term health problems. Faster recognition of sepsis can save lives. However, recognising sepsis in children can be difficult, as children with sepsis initially present with symptoms similar to common infections. Currently, the recognition of sepsis is based on physician assessment of patients, and laboratory tests. Sadly, a common finding in Coroner`s investigations of sepsis deaths is that parents represented several times to health-care facilities, stating their concerns that “something is wrong” with their child. There is at present great debate as to what role parental concern should have in sepsis recognition.

We hypothesise that parents as experts of their child provide important information to recognise disease severity in their child. We will perform questionnaires with parents, and with medical and nursing staff when a child is evaluated for sepsis. We will compare the value of measuring parental concern in comparison to healthcare worker assessment, clinical signs and symptoms, and routine infection markers.

Clinician decision making in peripheral intravenous cannulation in emergency settings

Peripheral intravenous cannulation (PIVC) is a vital part of modern medicine, however the use of cannulas has become prolific, with many never used. The patient risks that are associated with PIVC are well documented, including pain and infections, which can be severe and lead to death.

Reducing the rate of idle PIVCs (inserted but never used) may reduce the overall rate of risks, side-effects and infections associated with PIVC, but may also lead to patients who require PIVC not receiving one.

This study aims to describe: I) the proportion of PIVCs placed that do not get used within 24 hours (idle PIVCs), II) differences between the pre-hospital setting and the emergency department and III) the factors associated with clinicians’ decision making regarding PIVC insertion.

The Crystalloid versus Albumin in tThe Resuscitation of Emergency Department Patients with Septic Shock (CARESS) trial inflammatory marker pilot study.

The aim of this study was to determine whether 4% albumin solution is superior to saline for fluid resuscitation of patients presenting to the emergency department with septic shock.

Capacity Building Grant – third year: The Prince Charles Hospital

This grant provides a 'third-year' extension of funding as part of a 2011 EMF Capacity Building grant awarded to The Prince Charles Hospital Emergency Department. With the Capacity Building grant, the Department has engaged in more than 20 research projects. The majority involve significant input from the Hospital's emergency clinicians, who are working in collaboration with other Queensland and interstate emergency department and/or academic institutions such as CSIRO.

Implementation of Nasal High Flow: A Remote Context

In this study, the clinician-researchers are exploring whether nasal high flow (NHF) therapy can be safely and effectively used to improve health outcomes for infants with bronchiolitis in isolated remote communities, in particular for remote Indigenous Australians who have a higher incidence rate of bronchiolitis than non-Indigenous Australians. There is a desire by clinicians to implement NHF in remote areas, but this should undergo similar scientific scrutiny as previous published data.

NHF is a respiratory support system that provides support for people with respiratory conditions and is applied by high flow oxygen through nasal prongs. The therapy can avoid an escalation of care during hospitalisation. The safety of NHF has been widely studied in tertiary areas and regional hospitals, however, there is a lack of evidence to support safe use in remote settings.

In this study, the researchers are employing a two-phased approach: Firstly, an expert working party establishing agreed safe clinical boundaries for the NHF implementation and utilising expert viewpoints for implementation when managing infants with bronchiolitis. Secondly, a comparison of the outcomes before and after implementation to observe a reduction in escalation of care leading to reduced transfers. A community engagement process, with the focus to keep community members in their country/home environment, will be established to measure psychological, social-emotional and economic benefits of NHF.

Paediatric Reduction in Emergency Cannula Accidental REmoval Trial – PRECARE trial

The aim of this study is to evaluate securement devices for peripheral intravenous catheters (PIVC) in the paediatric ED to determine which method is most effective for reducing PIVC failure, associated costs, acceptability and patient distress.

Infants and children depend on PIVCs for the provision of medical therapy within the emergency department and during hospitalisation. However, PIVC insertion and management is challenging and more than 25% of devices fail. PIVC failure is costly for both the patient and healthcare organisation. Failure may require the child to undergo traumatic reinsertion procedures, delay important medical treatment and prolong length of hospital stay. One way to reduce PIVC failure is with effective PIVC dressing and securement, by ensuring correct catheter position in the vein.

Our trial aims to test if new advances in catheter securement, medical grade superglue (Histoacryl) and an integrated dressing securement product (SorbaView SHIELD), are effective at preventing cannula failure and complications in paediatric patients. Using a three arm, randomised controlled trial, this study will recruit 460 paediatric patients at two regional emergency departments (Logan Hospital, Ipswich Hospital). Children will be randomised to receive PIVC securement by i) standard care, ii) advanced dressing or iii) medical grade superglue and advanced dressing. The main outcome of this trial is PIVC failure, with other important questions surrounding cost effectiveness and patient comfort also to be explored.

It is important for effective, improved cannula security to be explored as this is frequently a first line device choice for treatment, being highly effective in rapid treatment situations. A result in improved treatment delivery will benefit with cost savings in not only product but clinician time spent re-inserting, and a reduction in unnecessary, painful procedures for children.
