Thousands of junior doctors start their new jobs today - dubbed "black Wednesday" because of links to higher death rates among patients.
Research has linked the first Wednesday in August to an increase in deaths of around 6%, as hospitals see not only newly-qualified doctors on their wards, but more experienced junior doctors move departments.
A majority of junior medics already working in hospitals across the UK also do not feel they have enough time to give patients the care they need, a new poll by the Medical Protection Society reveals.
Half of the 1,000 training doctors polled also said they had concerns about the quality of care in their workplace.
