Code of Medical Ethics Opinion 1.1.5
Physicians’ fiduciary responsibility to patients entails an obligation to support continuity of care for their patients. At the beginning of patient-physician relationship, the physician should alert the patient to any foreseeable impediments to continuity of care.
When considering withdrawing from a case, physicians must :
(a) Notify the patient (or authroized decision maker) long enough in advance to permit the patient to secure another physician.
(b) Facilitate transfer of care when appropriate.
