The NHS counter fraud team has saved the health service in Scotland £43m since it was formed 11 years ago, it has been revealed.Successes have included the conviction of a surgical theatre technician, who was jailed for stealing £23,000 worth of medical equipment to sell on eBay.A GP who was using false names to obtain prescriptions for opiate drugs for personal use was also caught.Public Health Minister Michael Matheson said NHS fraud would not be tolerated.He said: "Whether committed by staff, patients, clinicians or contractors, NHS fraud takes money away from where it is most needed."Although many of the cases may seem minor, the cost of fraud to our NHS really adds up."Already £43m gross has been saved which has been used to provide patient care and not line the pocket of fraudsters."Mr Matheson is due to meet the fraud team this week to find out more about their work and the nature of convictions.
