Suicide and Deliberate Self-Harm – an article from the British Medical Journal
http://bmj.bmjjournals.com/cgi/content/full/330/7496/891?ehom
This article appears in the latest edition of the BMJ and is worth a read as this is what doctors generally will be reading. It links suicide and deliberate self-harm more than I think is fair, however it is written from the point of view of trying to prevent suicide. The treatment advice I think is valid for self-harm itself; however I think that the fact that the purpose is focused on preventing suicide may indicate that doctors are still fairly unsure of how to deal with self-harm that lacks suicidal intent.
