In England and Wales there are at least 200,000 general hospital presentations for self-harm (intentional self-poisoning or self-injury) per year
- self-harm occurs in relation to a wide range of personal problems, emotional turmoil and psychiatric disorders. It carries a significant risk of subsequent suicide and has major impacts on family members and friends
Deliberate self-harm is defined as any act undertaken by a person mimicking the act of suicide, but not resulting in a fatal outcome.
Parasuicide is a very different phenomenon from suicide, not least in that there is a patient with which the health professional may work after the attempt.
