Who should provide expert opinion in emergency medicine-related medical litigation?

Expert evidence plays a central role in establishing the relevant standard of care in medical litigation. In Australia, little is known about the expert witnesses who provide evidence about the standard of care provided in ED. A sample of recent published case law suggests that a proportion of expert evidence about breach of the standard of reasonable care in ED is provided by medical practitioners who are not emergency physicians and/or have no recent practice experience in an ED. This may potentially distort the identification of the relevant standard of care. In the United States, the American College of Emergency Physicians has attempted to address this issue by developing and promulgating expert witness guidelines. Is there a case for the Australasian College for Emergency Medicine to assume an advocacy role and/or develop standards in this area?.
