Which principle involves refraining from harmful actions and keeping a patient's private information confidential?

The principle governing the need to refrain from harmful actions and to maintain patient confidentiality is best encapsulated within the Hippocratic Oath. This ancient ethical guideline serves as a foundational element in medical practice, embodying the commitment to do no harm, which aligns with the principle of nonmaleficence.

Additionally, it emphasizes the importance of maintaining confidentiality, which is vital in fostering trust between patients and healthcare providers. The Hippocratic Oath encourages physicians to protect the privacy of patients, thereby reinforcing the ethical standards of care and respect for personal information.

While state laws and medical ethics also play significant roles in healthcare practice, the Hippocratic Oath specifically addresses these core principles of avoiding harm and ensuring privacy in a direct and principled manner, as all healthcare practitioners are expected to adhere to these ideals.
