There were over 3,700 attacks on nurses in the HSE last year.
Nurses say hospital overcrowding has led to an increase in violence and threats toward them.
Healthcare workers have been subjected to more than 12 attacks a day in the last 15 months.
Figures released by the HSE show that threatening behaviour has also risen.
Victims will give their personal experiences at the INMO's annual conference in Sligo, which begins today.

Phil Ni Sheaghdha is the general secretary of the Irish Nurses and Midwives Organisation.
She says the problem is only getting worse.
"We have some very serious physical injuries, we have a lot of psychological issues due to aggression."
"We've had threatening behaviour towards nurses. Threats to follow them out to the car park and 'I know where you live.'"
"So we have a situation where people are getting increasingly frustrated at long waits in hospitals."
