Contrasts in acute medicine: a comparison of the British and Australian systems for managing emergency medical patients

Increasing numbers of patients are presenting for unscheduled medical admission to hospitals worldwide, prompting clinical redesign of "front-door" emergency medical services In the United Kingdom, there has been considerable investment in the establishment of acute medical units (AMUs) and the training of acute medicine physicians Some centres in Australia have established similar medical assessment units While these initiatives have undoubtedly met with some success, the evidence base for their overall benefit remains elusive We describe key aspects of the recent establishment of acute medical services in Britain and discuss the relevance of these experiences to Australia Successful models of care in acute medicine have often been shared with other centres The adaptation of existing models of care to meet local demands is superior to simply adopting an existing model Once the desired clinical functionality of a service is determined, informed decisions can be made on staffing requirements, skill mix, and the structure of any new clinical unit The functionality of the acute medical service, rather than simply the physicality of an AMU, should drive service design MJA 2010, 193 227-228
