Emergency medicine research

• It is estimated that nearly 1 in 4 Australians seek emergency care each year.
• Around 10% of emergency presentations are to private hospital emergency departments. The St John of God Murdoch Hospital Emergency Department in Western Australia is the only private emergency department in the state conducting this type of research.

• Use of acupuncture for pain relief in the ED
• Quality of cardiopulmonary resuscitation (CPR) delivered by emergency doctors and nurses
• Why paramedics bring patients to a private ED
• Patient flow within the ED

CTPA in ED
Emergency physicians remain very concerned about both the overuse and underuse of computed tomography pulmonary angiogram (CTPA), the investigation of choice in the work-up of suspected PE in ED. In conjunction with colleagues across Australia and New Zealand, we performed a study to establish the range of CTPA positive yield which departments and individual clinicians can use as a clinical indicator against which to compare their own performance.

Why paramedics bring patients to a private ED?
The reasons why patients self-present to a private ED are well established, however, the role paramedics play in this decision for patients presenting via ambulance is unknown. This study investigated paramedic’s motivations for presenting to ED, and their perceptions and expectations of the visit, through paramedics participating in short structured interviews.

CPR skills in ED
Survival rates post cardiac arrest are impacted by the quality of cardiopulmonary resuscitation (CPR), with increasing evidence that high quality CPR improves survival and favourable neurological outcomes. There is documented evidence that healthcare providers, in ED or elsewhere, are not better than lay persons in adhering to the guidelines when performing CPR. This study aims to ascertain if the deficit is in ED staff knowledge of the guidelines or in their ability to translate their knowledge into practice.

Acupuncture in the emergency setting
Providing an alternative holistic viewpoint on pain management in the emergency department, Prof Andrew Jan’s PhD is designed to investigate the effect of acupuncture on acute pain management in the emergency setting. We are currently undertaking a pilot trial investigating the use of a brief, ED suitable technique known as battlefield acupuncture. This research will establish the role of acupuncture as a stand-alone or adjunctive technique in emergency medicine.

Patient flow in the ED
Efficient patient flow through the Emergency Department (ED) is important for quality of care, patient outcomes and patient satisfaction. Improving patient flow can be achieved by reducing the amount of time patients spend in the ED, thereby reducing departmental crowding. This study aims to observe the effects of operational changes on ED wait times, length of stay and patient satisfaction.
