Retrieval

Essentials 1 Mature retrieval systems act as a single point of entry for the referrer, preferably providing services by initiation of a single call to a systemwide phone number. 2 Retrieved patients are often unstable, at the margin of physiological compensation, and in need of specialized investigation and intervention. They are often at that phase of an emergency presentation where diagnosis is incomplete, treatment is problem-focused…

Pre-hospital emergency medicine

Essentials 1 Ambulance call taking and dispatch is increasingly becoming computerized, which allows for the medical determination of the most appropriate response speed and skill set as well as telephone instructions for cardiopulmonary resuscitation and first aid. 2 Ambulance care of the critically ill or injured patient is similar to initial evaluation and management by an emergency physician, with emphasis on basic life-support measures. 3 The…

Ethics in emergency medicine

Essentials 1 Ethics is about doing the right thing for the patient. 2 The morality of the doctor and the morality of the patient will influence decision making. 3 The two most common ethical dilemmas in emergency medicine concern treating patients who do not consent and stopping resuscitation. 4 When these dilemmas are being addressed, the application of pragmatic tools assists ethical decision making. 5 The…

Privacy and confidentiality

Essentials 1 Privacy and confidentiality issues can be related to the physical environment in which care is given or to the personal health information involved in the patient’s care. 2 Breaching confidentiality of personal health information now breaks Australian and New Zealand legislation. Introduction An individual’s right to privacy and confidentiality has gained increasing recognition over the past decade. In an emergency setting, where patients are…

Consent and competence—the Australian, NZ and UK perspectives

Essentials 1 Informed consent is an essential process for medical treatment that has ethical, legal and administrative elements. Complexities of the practical situation may result in deviation from the theoretical ideal. 2 Consent may be implied, verbal or written, and should always be clearly documented. 3 Consent must be informed, specific and freely given, and must cover that which is actually done. 4 The patient must…

The coroner: the Australian, NZ and UK perspectives

Essentials 1 The Coroners Court is a specialist court established to investigate certain types of deaths and fires. The purpose of these investigations is to consider ways that similar events may be prevented in the future. 2 Preparation for a coronial investigation should start as soon as someone dies in reportable circumstances. 3 A coronial inquest is generally a public inquiry into a death to which…

Mental health and the law: the Australian, NZ and UK perspectives

Essentials 1 The emergency department is frequently the point of access to the mental health system. 2 Emergency physicians need to be able to distinguish between patients with physical and those with psychiatric illness. 3 Patients should only be committed involuntarily to an approved hospital if they have a mental illness requiring immediate treatment for their own health or safety or the protection of others and…

Postgraduate emergency medicine teaching and simulation

Essentials 1 Emergency medicine training programs need explicit curricular objectives, effective learning and teaching strategies, and valid and reliable assessment methods. 2 Technology, social media and online collaboration are affecting the way emergency medicine trainees and their supervisors learn and access information, and demand new skills in information retrieval and critique. 3 Simulation offers learning opportunities in clinical and procedural skills, teamwork and communication, and requires…
