'Who cares for the carer?' asks punched emergency worker
The number of warnings for ambulance crews about people who could be violent or pose a risk has increased nearly ninefold in 18 months.
The Welsh Ambulance Service had 434 people or addresses listed as potentially violent or a risk to crew safety in July, up from 50 in January 2016.
It may mean a request for police support if a 999 call is made for an ambulance crew at a specific address.
Emergency medical technician Dean Caldwell, who was punched by a patient, said incidents do give him a "knock back".
But he said: "Who cares for the carer? We still jump in the ambulance."
