Health care guidelines are intended to promote health, prevent harm, encourage best evidence-based care and economise the delivery of such care. Health care guidelines should be developed in consideration with the highest quality available evidence, in consultation with multidisciplinary committees, informed by consumer and community groups at every stage and disseminated and translated to every point of care. We are in the process of reviewing all the evidence-based guidelines from 2013 onwards (consistent with the introduction of Diagnostic and Statistical Manual for mental disorders version 5 [DSM-5]), focused on eating disorders in Australia. The review will detail the types of guidelines that exist, on which populations, their limitations, similarities/dissimilarities, to highlight valuable information that may be lacking (e.g., health outcomes, resource use and cost data often needed for assessing economic value of a health intervention, program or policy), to assess the quality of the guidelines available, and to identify gaps.
