Suicide is the most common cause of death for young people in the UK and around 50% of completed suicides in young people have previous self-harm as a theme. Hence, robust management of young people presenting with self-harm to the emergency department is crucial.

In this editorial we discuss the difficulties faced when navigating NICE 2004 guidance documents with the realities of the coalface and consider the prospects for current practice and the future with the NICE 2022 guidance.
