This chapter reviews models of service delivery, the evidence to support them and the associated recommendations in clinical guidelines. Family therapy approaches are often the treatment of choice for clinicians working with eating disorder patients in child and adolescent psychiatry, owing to their familiarity with systemic approaches and also a growing evidence base. Inpatient treatment programmes generally consist of a mixture of elements, usually involving a combination of nutritional and medical rehabilitation, psychotherapeutic treatment, psychosocial rehabilitation and often family interventions. For those patients not requiring the intensity of inpatient treatment but requiring more than an outpatient programme, day hospital treatment may be considered. In choosing between different models of service, availability is a major consideration, with patients as well as referrers sometimes having to weigh up the advantages of a locally accessible service with those of a more comprehensive service at some geographical distance.
