Which statement about patient confidentiality is correct?

In the context of patient confidentiality, the statement that a patient must sign a written release before any confidential information can be disclosed is particularly important because it emphasizes the need for patient consent to share private health information. This principle is rooted in legal and ethical standards for healthcare, which prioritize the autonomy and privacy of patients.

Obtaining a written release ensures that patients are aware of what information is being shared and with whom, allowing them to maintain control over their personal health information. This requirement helps to protect patient privacy, fosters trust in the healthcare system, and aligns with regulations such as the Health Insurance Portability and Accountability Act (HIPAA), which governs the sharing of medical information in the United States.

On the other hand, the other options do not accurately reflect the principles of confidentiality and the rights of patients. For instance, patients in public settings still maintain confidentiality rights, minors and wards of the state often have protections under the law, and signing a release does not mean relinquishing all rights to privacy—it simply allows for specified information to be shared.
