More than 6,000 people turned up at emergency departments across Northern Ireland in 2015 having self-harmed.
The majority were young people, aged between 15 and 24.
Records show that a number of people sought help on more than one occasion with over 8,500 incidents in 12 months.
The statistic is part of the chief medical officer’s annual report which reflects on the health of the population in Northern Ireland.
Dr Michael McBride said when it comes to mental health and in particular, self-harm, there is a need to intervene.
“We need to be aware that people who self-harm repeatedly are at much higher risk of taking their own lives by suicide” he said.
A self-harm registry which operates across all acute hospitals is designed to improve understanding about self-harm and to allow for comparative analysis with the Republic of Ireland and parts of England.
In its latest report, the registry concluded that Northern Ireland continues to have a high rate of self-harm.
While alcohol is a factor, drug overdose was the most common method of self-harm.
In his 9th annual report, Dr Michael McBride, gives a wide-ranging review of the service, including health inequalities, vaccination and screening programmes and dental health.
However, he also emphasises that the quality and advances in health care are not the only determinants of good health.
