Abstract: The aim of this paper is to compare the Emergency Nurse Practitioner role in the UK, Australia and New Zealand. Whilst geographically distant, the role of the Emergency Nurse Practitioner within these three countries shares fundamental similarities, causing the researchers to question, is this a time to implement international standards for the role? The Emergency Nurse Practitioner role in all three countries is gradually establishing itself, yet there are shared concerns over how the role is regulated and deficits in standardisation of scope of practice and educational level. Together these issues generate confusion over what the role embodies. The authors suggest that one method of demystifying the Emergency Nurse Practitioner role would be to progress towards international standards for regulation, education and core components of practice.
