Sir Liam Donaldson, chief medical officer, DH

The nation’s doctor survived junior doctors’ calls for his resignation over changes to their training and still continues his quest to improve patient safety. Having warned that primary care trusts continue to under-report breaches of patient safety, he has also most recently revealed plans for doctors to be revalidated every five years and told HSJ that the annual health check’s core standards were not strong enough on patient safety.

His annual report called for 30-day survival rates after surgery to be made public.

Sir Liam is clearly passionate about health and has influence over the medical profession, but questions remain over his impact on policy makers.
