Which of the following is an example of breach of confidentiality?

Breach of confidentiality occurs when sensitive information about a patient is disclosed without their consent, especially in a context where the information can be accessed by unauthorized persons. Discussing a patient's condition publicly exemplifies this breach because it involves sharing private health details outside of the appropriate and confidential healthcare settings. Such discussions can compromise a patient's privacy and trust in healthcare professionals.

In contrast, documenting a patient's medical history is a standard practice in healthcare that protects patient care and maintains a record for medical professionals. Sharing health information within care teams is crucial for coordinated care and is conducted under strict confidentiality agreements. Informing the patient about their treatment is also an essential communication practice that supports patient autonomy and informed consent. These activities are necessary parts of patient care that respect and uphold confidentiality rather than violate it.
