This review considers several recent concepts regarding aetiology and treatment of accidental hypothermia. The importance and effectiveness of shivering heat production in the attenuation and reversal of hypothermia is described. Immediately following removal from cold stress, the patient is in danger of a deteriorating condition that may be due to collapse of arterial pressure and/or continued decrease of core temperature. ⋯ In the emergency department, several factors should be considered before deciding on a treatment regimen. These factors include level of consciousness, cardiovascular stability, core temperature and the direction of change of core temperature. It may be advantageous to transport the more severely hypothermic patient to a more advanced care facility even though transport time may be greater.

The differential diagnosis of the hyperpyrexic patient in the emergency department is extensive. It includes sepsis, heat illness including heat stroke, neuroleptic malignant syndrome, malignant hyperthermia, serotonin syndrome and thyroid storm. ⋯ However, establishing the correct diagnosis is a challenge in the setting of the obtunded emergency patient who gives no history and where there may be limited access to any past medical or drug history. This paper presents such a case and reviews the features of the differential diagnoses and management of the hyperpyrexic patient.

Setting the benchmark for research in the management of acute pain in emergency departments.
The aim of this study was to define the degree of change on a visual analogue scale that corresponded to a clinically meaningful reduction in the level of pain reported by patients experiencing acute pain. ⋯ When evaluating treatments for acute pain, a difference in visual analogue scale pain score of less than about 20 mm is unlikely to be clinically meaningful. Studies should be designed and reported relative to this benchmark rather than the minimum clinically significant difference in visual analogue scale pain score.

Multicenter Study Comparative StudyNTS versus waiting time: an indicator without definition.
The National Triage Scale versus waiting time is a key performance indicator for Australasian emergency departments. However, the point at which the clock starts to measure waiting time has not been defined. The aim of this study was to determine how this indicator is measured in Australia, as well as a number of other issues relating to the application of the National Triage Scale. ⋯ The measurement of this key performance indicator is not consistent across Australia. Therefore, caution is advised when comparing such data between departments. The Australasian College for Emergency Medicine should produce operational definitions relating to the use of the National Triage Scale in order to provide meaningful comparative data.

Implementation and evaluation of an undergraduate emergency medicine curriculum.
To describe the implementation and evaluation of an undergraduate course in the first Australian academic emergency medicine unit. ⋯ Undergraduate emergency medicine education should become an essential part of Australian and international undergraduate medical education. Emergency medicine is enjoyable and eminently suitable for problem-based, interactive and integrated teaching and improves confidence, clinical experience in emergencies, practical skills and teamwork. Improvements include more problem-based teaching, more practical skills sessions and better definition of student roles. These are general principles that can be applied to other undergraduate courses and to designers of other emergency medicine courses, both undergraduate and postgraduate.
