Doctors don't trust their colleaguesDoctors are widely sceptical about the abilities of their colleagues – and doubt that dangerous doctors will easily be detected, according to a survey published today.

More than 80% of doctors said they had colleagues they would not want to treat their family or friends in a survey conducted by Doctors.net.uk.

And 53% said revalidation would not identify failing doctors.

The poll was released ahead of the tenth anniversary of the death of Dr Harold Shipman, the GP alleged to have murdered dozens of elderly patients.

The survey suggests many doctors do not believe that revalidation could identify a doctor like Shipman.

But the British Medical Association today said revalidation was not intended to catch people like Shipman.

Some 4,600 doctors and 1,000 GPs took part in the survey. Some 86% of hospital consultants said there were doctors they would not want to treat their friends or family - while 67% of GPs said this.

The survey found GPs massively more sceptical of the benefits of revalidation than hospital doctors. Some 63% of GPs said the benefits of the process would not outweigh the extra administrative costs. This compared with 38% of hospital doctors.
