[Eating disorders and psychiatric day hospital treatment]

Eating disorders are complex pathologies characterised by the entanglement between physical and mental aspects and by their high impact on health. Studies on care models showed the need for other therapeutic modalities due to the complexity of treatments, the risk of recurrence after hospitalisation, as well as to the cost and duration of hospital stays. Day hospitals specific to these disorders have been created, albeit with very few studies. Even though the available studies tend to find good therapeutic efficacy, they are disparate, describing care centres that are rather different in their structure and theoretical approach, and factors of therapeutic efficacy are not always well described.
