The changes create a specific offence of causing nuisance or disturbance on NHS premises and give the police and authorised NHS officers the power to remove people.

However, the powers do not apply to patients seeking medical advice, treatment or care for themselves.

The new powers, which are part of the Criminal Justice and Immigration Act 2008, are designed to protect staff, patients and visitors so that vital NHS services can continue without disruption.

They have been developed in partnership with the Anti-Violence Collaborative, Police, Crown Prosecution Service, NHS Wales organisations and trade unions.

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.'

The latest findings from the All‑Wales NHS Staff Survey shows a sharp drop in staff feeling safe from abuse by patients and the public, falling from 83.6% to 74.8%.
