How can a medical facility prove that a patient has consented to the disclosure of medical information? by attesting that the patient understands confidentiality requirements by explaining that the patient verbally agreed to the condition by showing that the patient has signed a consent form by demonstrating that the patient is over the age of 18 years old

by showing that the patient has signed a consent form

Explanation:

The consent form must be signed by the patient after the doctor clarifies the patient's diagnosis, prognosis, available means and forms of treatment and their risks. From this information the patient can exercise his autonomy and make a free decision on which procedure will be submitted, so he must sign the consent form stating that he agrees with the treatment chosen and the consequences that may arise. In addition, the consent form may show that the patient has allowed the disclosure of medical information about him.
