NICE guidance, eating disorders and older people.

BACKGROUND

The treatment of eating disorders by the National Health Service in England and Wales adheres to the National Institute for Health and Care Excellence (NICE) guidelines, which were informed by an experimental evidence base.

AIMS: As the presentation and treatment of eating disorders have been shown to vary on the basis of age, we aimed to review the representation of older people in the evidence base for the NICE guidelines.

METHOD: The evidence base was reviewed by identification of participant ages and the recruitment methods used in the experimental literature. The use of clinician referral was of particular interest, owing to the age-dependent risk of eating disorders being misdiagnosed in older adults.

RESULTS

The results highlighted low participant ages across the evidence base, most notably in anorexia nervosa samples. In accordance with the age data, a high frequency of clinician referral was used to recruit participants, with the highest rate identified in anorexia nervosa samples.

CONCLUSIONS

NICE guidance fails to consider the economic, social, political and health contexts around onset or chronological development of an eating disorder, with no reference to comorbidities which are commonly reported with older people or how this might affect diagnosis, formulation and treatment recommendations. Research is urgently required to inform clinical recommendations for older adults.
