Which action is necessary for ensuring patient confidentiality?

Maintaining patient confidentiality is a critical aspect of healthcare that protects the privacy of patients and upholds ethical and legal standards. Documenting and sharing information only with authorized personnel is essential because it ensures that sensitive patient data is only accessed by those who have the right to know, such as healthcare providers involved in the patient's care or authorized administrative staff. This practice helps to prevent unauthorized access to personal health information, thereby safeguarding the patient's privacy and maintaining the trust essential for effective healthcare delivery.
