Australian and New Zealand Clinical Practice Guidelines for the Treatment of Anorexia Nervosa

Abstract

It is extremely difficult to draw general conclusions about the efficacy of specific treatment options for AN. There are few controlled clinical trials and their quality is generally poor. These guidelines necessarily rely largely upon expert opinion and uncontrolled trials. A multidimensional approach is recommended. Medical manifestations of the illness need to be addressed and any physical harm halted and reversed. Weight restoration is essential in treatment, but insufficient evidence is available for any single approach. A lenient approach is likely to be more acceptable to patients than a punitive one and less likely to impair self-esteem. Dealing with the psychiatric problems is not simple and much controversy remains. For patients with less severe AN who do not require in-patient treatment, out-patient or day-patient treatment may be suitable, but this decision will depend on availability of such services. Family therapy is a valuable part of treatment, particularly for children and adolescents, but no particular approach emerges as superior to any other. Dietary advice should be included in all treatment programs. Cognitive behaviour therapy or other psychotherapies are likely to be helpful. Antidepressants have a role in patients with depressive symptoms and olanzapine may be useful in attenuating hyperactivity.
