I doubt that you'll be seeing any of those again; I imagine they will all be long gone. frown

Anyway, let me put that right for you:-

"... the patients families don't realise care how expensive bits of kit are and they get thrown away before we can retrieve them".

And, "thrown away"? - or "sold"? think

Or, put another way, maybe they have realised how valuable they are.

Either way, the solution is:- bill them! smile
