How Arato v. Avedon applies in Missouri: state-specific rules, key cases, and bar exam notes for Torts (Medical Malpractice – Informed Consent).
In Missouri, the principles established in Arato v. Avedon regarding informed consent are primarily embodied in the requirement that medical practitioners disclose all risks and benefits associated with a proposed treatment that a reasonable patient would consider significant in the decision-making process. Missouri law emphasizes the patient's right to autonomy and informed decision-making in medical contexts.
Missouri law holds that a physician must disclose material risks associated with a treatment, and failure to do so can be grounds for a medical malpractice claim based on lack of informed consent.
The court held that a physician's failure to inform the patient of significant risks associated with surgery constituted a lack of informed consent.
This case reaffirmed the principle that informed consent requires disclosure of risks that a reasonable patient would need to know before consenting.
The court found that the physician’s duty to inform extends not only to risks of the treatment itself but also to alternative treatment options.
Missouri's approach closely aligns with the federal standard of informed consent as established by cases like Canterbury v. Spence, which also emphasizes the patient's right to understand the risks involved. However, Missouri has developed its own nuances through state-specific case law that may differ slightly from the federal standard regarding what constitutes material information.
Questions regarding informed consent and medical malpractice may appear on the Missouri bar exam, particularly in the context of evaluating whether the physician adequately fulfilled their disclosure obligations.
