Which principle is fundamental for maintaining patient confidentiality in prescription records?

Maintaining patient confidentiality in prescription records is primarily governed by the principle of limited access to authorized personnel. This principle ensures that only those individuals who have a legitimate need to know—such as healthcare providers directly involved in a patient's care or administrative staff with specific roles—can access sensitive patient information. This access control is crucial for safeguarding patient privacy and complying with legal and ethical standards, such as the Health Insurance Portability and Accountability Act (HIPAA) in the United States. By restricting access to prescription records, healthcare facilities can help prevent unauthorized disclosures that could compromise patient confidentiality.

Other options, such as the use of color-coded files or public disclosure policies, do not promote confidentiality; in fact, they can lead to increased risks of exposing sensitive information. General access for all staff is also contrary to the principle of confidentiality, as it would allow personnel without a specific need to view prescription records, further undermining patient privacy. Therefore, limited access to authorized personnel is essential in maintaining the security and confidentiality of prescription records.
