The report cited seems to suggest that mobile phones and laptops are the most likely targets. No surprises there - as they would be (are) easier to fence (turn into cash) than, say, an ECG Recorder or a box of oxygen flowmeters.
Unfortunately, "screwing it to the wall" or "bolting it to the floor" doesn't really work in many (most?) cases.
Chains and locks (pad-locks) are all very well, until staff "forget" to use them (or leave them unsecured - "in case they lose the keys")!
Maybe increased staff vigilance, better security (staff) and bothering to use the many CCTV cameras dotted around could help. Not forgetting RFID tagging.
All that assumes, of course, that the staff themselves are not the ones doing the "tea-leafing"!
What could be of greater interest (to me, at least) is how many of the thieves have been prosecuted, and what sentencing did they receive.
"Prevent" theft, John? "Deter", at best, I would suggest.
In passing, there are good reasons why hospital drugs are (or should be - a legal obligation, in fact) kept safely locked away.TR Fastenings
