The Medical and Dental Defence Union (MDDUS) issued the advice ahead of planned BMA industrial action on 21 June - when GPs will only see patients who are, or consider themselves to be, an emergency.
The MDDUS has advised any GPs taking part in the action to take a cautious approach when treating patients on the day.
MDDUS head of professional services Dr Jim Rodger said: ‘If there is any doubt about what constitutes urgent care they should treat first and ask questions later.’
Dr Rodger said that doctors taking part must follow the GMC’s Good Medical Practice and ensure that patient safety was not compromised by the action.
He said: ‘Doctors should make adequate arrangement prior to June 21 to help protect patient safety. This includes providing patients with information via posters, leaflets or the practice’s website so they are aware of how the action may affect them.’
