GPs are reporting very few of the many thousands of errors they make in treating and diagnosing patients. See Telegraph article. To be honest, I'm very surprised to read that they report any. The GPs who have so badly harmed me have certainly never reported those mistakes. Nor has any other health professional who has harmed me. And I've never personally heard of any healthcare worker reporting their mistakes to anyone. That's one of the reasons they never learn from their mistakes of course.
