A new campaign has been launched in an attempt to tackle abuse of NHS staff, particularly over the festive season.
The Health Minister, Lesley Griffiths, said a similar crackdown on offenders has resulted in more successful prosecutions against those who are abusive towards staff.
In 2008 - 2009 there were eight prosecutions for violence towards NHS staff. Over the last 30 months there have been 387 successful prosecutions.
The campaign uses posters in hospitals and surgeries across Wales warning that verbal or physical abuse will result in prosecution.
