Nurses were victims in almost 70% of total assaults on hospital staff over the last ten years, according to HSE figures.
Between 2008 and the end of November this year, 10,744 staff reported assaults ranging from actual harm to 'near misses' and complaints, the figures released to Sinn Féin's health spokesperson Louise O'Reilly show.
More than 7,500, or over 70%, of those assaults targeted nurses.
So far in 2018, 948 incidents have been reported. In 61% of them, nurses were the victims.
Doctors reported 25 assaults while other grades, including catering and housekeeping staff, reported another 339 incidents.
The HSE stresses that not all reported attacks involved actual harm, but could include "near misses", dangerous occurrences and complaints involving physical, verbal or sexual assault.
However, it expects the statistics to rise in the future as staff are encouraged to formally report every incident.

The HSE will be placing a renewed emphasis on the management of work-related aggression and violence in 2019 to support the organisational strategy.
Ms O'Reilly - a former SIPTU nursing official - urged the HSE to employ more security staff in emergency departments to ensure hospital employees are protected.
