Figures just released by the health minister for 2015/16 revealed 6,057 staff across the health service were assaulted while a further 2,325 staff suffered verbal abuse.
This includes ambulance staff who were attacked 160 times in the course of their duties.
Belfast Health and Social Care Trust accounted for the most attacks with staff employed there subject to 3,562 incidents of verbal and physical abuse.
In each of the five health trusts and the ambulance service physical attacks on staff have increased year on year for the past three years.
The latest figures were released by Health Minister Michelle O’Neill in response to a written Assembly question from UUP MLA Jo-Anne Dobson.
The minister said: “Each Health and Social Care (HSC) Trust has a robust zero tolerance policy in place with a senior director responsible for ensuring staff safety and support is properly and consistently managed across the trust.
“This is underpinned by health and safety legislation, which places a duty on trusts to provide a safe and secure environment for staff and others.”
