New legal protections have come into force in Wales to protect NHS staff from nuisance and disruptive behaviour in hospitals.
The changes make it a specific offence to cause nuisance or disturbance on NHS premises and give the police and authorised NHS officers the power to remove people.
Nuisance and disruptive behaviour could include verbal abuse, physically obstructing corridors, preventing staff from carrying out their duties and creative excessive noise in waiting areas, wards and other areas.
The powers do not apply to patients seeking medical advice, treatment or care for themselves.
The new powers are part of the Criminal Justice and Immigration Act 2008 and have been developed in partnership with the Anti-Violence Collaborative, Police, Crown Prosecution Service, NHS Wales organisations and trade unions.
The latest findings from the All‑Wales NHS Staff Survey show a decrease in staff feeling safe from abuse by patients and the public, from 83.6 per cent to 74.8 per cent.
Cabinet Secretary for Health and Social Care, Jeremy Miles said: "These powers strengthen protections for our NHS staff and help ensure that our hospitals and healthcare settings remain safe for staff and patients where care can flourish.
"This is about safety, dignity and supporting the workforce. It does not criminalise people seeking care - it ensures that staff can do their jobs free from fear and people can receive treatment in calm, secure environments.
"Today's action sends a strong, positive signal: in Wales we stand with our NHS workforce."
Chair of the Anti-Violence Collaborative, Jonathan Webb said: "This represents a further milestone in the collaboration between health services and the criminal justice sector in responding to incidents of violent behaviour exhibited by a minority of service users.
"It empowers NHS staff to take appropriate action when confronted with unacceptable behaviour and provides an effective resolution to deal with incidents that do occur.
"We hope that this further reduces the number of incidents of violence and aggression seen in NHS Wales."
