Similarly, a family member visiting a patient is a normal part of care and support that generally does not infringe on privacy unless they divulge sensitive information without consent. A medical conference discussing case studies typically aims to enhance medical knowledge and is conducted under guidelines that protect patient identity and confidentiality, provided proper protocols are followed. Thus, these scenarios do not inherently signal a breach of patient privacy as the
