A total of 150 homes across Tayside, Fife and Forth Valley are blacklisted by ambulance chiefs, who will not allow their staff to enter without police protection.
The statistics were described as “staggering” by one MSP, who insisted they are evidence of a “real problem” with crime and disorder.
Across Scotland 593 addresses have been blacklisted because of previous attacks or threats on paramedics an increase of more than 150 from this time last year.
It means even in the most serious of emergencies, ambulance staff cannot enter the properties unless police officers are present.
The statistics, obtained through freedom of information legislation, reveal NHS Lothian had the most ‘red-flagged’ addresses in Scotland, with 162. Fife has 68. Tayside and Forth Valley each have 41 “no-go” addresses.
Jackson Carlaw is health spokesman and deputy leader of the Scottish Conservatives.
“This is a disgraceful situation, and those who have caused this only have themselves to blame if they lose out on medical treatment in the future,” he said.
“It shows, despite SNP claims, we still have a real problem with crime and disorder in Scotland, and it needs to be clamped down on.”
When contacted by The Courier, a Scottish Government spokesman said: “Violence against NHS staff is completely unacceptable and will not go unpunished.
“However, crime is at a 37-year low in Scotland and this represents a very small proportion of around 2.5 million residences across the country.
“We take the safety of our NHS staff very seriously, that is why they have the support of their police colleagues. More people than ever before are being convicted under the Emergency Workers (Scotland) Act, with the penalty up to 12 months’ imprisonment, a £10,000 fine or both.”
A spokesman for the Scottish Ambulance Service said: “All crews are given training in management of aggression and how to undertake a full risk assessment on arrival at scene to establish if there is any potential danger.
“If any ambulance crews feel their safety may be compromised, they are instructed to hold nearby the scene and await support from the police, or additional ambulance crews.
“As a further protective measure, addresses where there have been previous incidents of violence or threatening behaviour towards staff are flagged in control rooms,” he added.
