The UK's leading bacteriologist has called for an extra 30 milion of Government funding to help fight hospital superbugs.

Aberdeen University's Professor Hugh Pennington believes a multi-million-pound war chest should be set aside to build isolation wards in hospitals.

The Scottish Government has already pledged 54million over the next three years to tackle hospital-acquired infections (HAI) - including 5.4million to recruit 600 cleaners.

But Professor Pennington claims the only way to beat superbugs, such as MRSA and Clostridium difficile (C.diff), is to establish purpose-built isolation units to treat infected patients.

He said: "If we crack these bugs properly, then we will be spending much less on dealing with the consequences. Those looking to save money should see this (investment) as an insurance policy."

HAIs cause around 380,000 bed days to be lost each year around Scotland.

The Scottish Government is committed to providing single rooms for patients hit by the bugs in all new hospitals.

But yesterday Professor Pennington warned that further investment is needed to ensure those at risk of spreading infections are removed from wards.

He said: "Money is an issue here because this requires building isolation rooms for patients and also having the staffing levels to run these properly. If we can stop the bug transmitting to other patients then we will have half the outbreaks."

The Scotland Patients' Association backed the proposals, and went further by suggesting that there should be a specialist infection hospital in each board area.

Chairwoman Margaret Watt said: "Of course this is a good idea, but it should have been done a long time ago as we have been saying for years."

A Scottish Government spokesman said a raft of measures to tackle the bugs had been brought in, and C.diff and MRSA cases had fallen in recent years.

"HAI is a challenge which goes beyond party politics and we welcome suggestions, such as those from Professor Pennington, as to how we can best tackle infections and maintain public confidence," he added.
