from today's UK Independent newspaper ...............

As many as one in seven hospital procedures are unnecessary, leading to "profligate" waste in the health service, a senior NHS official has said.

Sir Bruce Keogh, the medical director of NHS England, was quoted by The Sunday Telegraph as saying he estimated about ten or 15 per cent of treatments should not have been carried out

"it's the same the whole world over ...."

I think the difference here is that it's the other way around: only one procedure in seven is actually necessary. The other six are just to bump up the bill.
