Medical professionals have a responsibility to adhere to evidence-based medicine and uphold public trust. Spreading significant medical misinformation that could directly harm patients or public health can have serious consequences for a doctor's license.
Professional Ethics: Medical boards and professional organizations generally expect doctors to provide accurate, evidence-based information to their patients and the public. Promoting information that is scientifically disproves and potentially harmful violates these ethical guidelines.
Patient Safety: If a doctor's advice leads patients to make decisions that put their health, or the health of their children, at significant risk (like not vaccinating against serious diseases), it can be considered a breach of their duty to care and a threat to patient safety.
Regulatory Action: State medical boards (in the US) or equivalent regulatory bodies in other countries have the authority to investigate complaints against doctors and take disciplinary action, which can range from warnings and reprimands to suspension or revocation of a medical license. This typically occurs when a doctor's conduct falls below professional standards, jeopardizes public safety, or involves the dissemination of harmful misinformation.
The specific outcome for a doctor in such a situation would depend on the laws and regulations of the jurisdiction where they are licensed, the specific actions they took, and the findings of any investigation by the medical board. However, promoting information that contradicts established medical science and can endanger public health is a serious matter that can indeed lead to disciplinary action, including the loss of a medical license.
