All doctors are entitled to withdraw their treatment of a patient or refuse to treat a patient in certain circumstances. You must follow the ethical standards set out in the Medical Council’s A Guide to Professional Conduct and Ethics 2009 (see Sections 8, 9 and 14 for more information).
Once you undertake the care of a patient, you should usually continue to care for them for the duration of their illness. If you decide to withdraw your services, you still have an ethical duty to continue to care for the patient until alternative arrangements for care are put in place. Remember, you remain under a duty to provide care in emergency situations at all times.
