Leaflets and advice given to staff and visitors
Police have teamed up with health bosses at Morriston Hospital to crack down on car crime.
Crime prevention leaflets have been handed out to patients, staff and visitors before police move on to Singleton Hospital and Bridgend's Princess of Wales Hospital.
ABMU' Health Board's Assistant Director of Strategy Des Keighan said vehicle crime was a comparatively small problem at Morriston Hospital - in fact, only 28 incidents had been reported in the last year across the health board.
These ranged from vehicles being damaged by other cars, to theft from, and of, vehicles.
Mr Keighan said: "We have been working with South Wales Police to marry their agenda for crime prevention with issues affecting the health board.
"We have now launched the vehicle crime initiative.
"We targeted visitors as they came into the hospital and did a leaflet drop on cars to raise awareness about good practice to keep vehicles and valuables secure.
"We're starting at Morriston Hospital and we are looking to run the same initiative at Singleton and Princess of Wales hospitals within the next month.
"Later in the year we will be working with the police to look at other issues we want to highlight, such as violence and aggression, and theft."
Sergeant Gareth Prosser, Deputy Local Policing Inspector for the Morriston and Eastside sectors, said people could take simple steps such as ensuring vehicles were locked with no valuables left on display.
"It's a very stressful time for patients and visitors, and we want to make sure everything is in order when they return to their vehicles," added Sergeant Prosser.
"We regularly work with Morriston Hospital to reduce crime and the fear of crime, and we deal proactively with any offences that do take place."
