professional codes, data protection obligations of

Providers’ "information obligations" are routinely traced back to the Oath of Hippocrates, constructed sometime between the sixth century BCE and the first century CE. It enjoins that what is seen or heard in the course of treatment be kept to oneself and not "spread abroad."

Ethical codes of the nineteenth century such as Thomas Percival’s continue the Hippocratic tradition, promulgating a physician’s obligation of "secrecy and delicacy" regarding information obtained in the "familiar and confidential intercourse" of a professional visit.

Modern examples include the current American Medical Association Principles of Medical Ethics, which requires that practitioners "shall safeguard patient confidences and privacy within the constraints of the law." The American College of Physicians Ethics Manual includes confidentiality among its "fundamental tenet[s] of medical care."

Strictly speaking, the Hippocratic oath and its progeny apply only to physicians. But almost all of the other health care professions, such as nursing and psychology, have analogous professional norms and codes. So do most of the organizations representing allied health professionals. So do groups representing health information specialists, such as AHIMA/HIMSS.

The American Hospital Association Patient Care Partnership (which replaces the AHA Patient's Bill of Rights) states that patients are entitled to "respect [for] the confidentiality of your relationship with your doctor and other caregivers, and the sensitive information about your health and health care that are part of that relationship."

Managed care has made matters vastly more complicated. In a world where medical information exchange is common, and individual providers sometimes have little control over downstream data uses, sorting out confidentiality rules in actual practice can be more difficult than ever.

Some areas of legally mandated disclosure are still clear, particularly those related to public health and safety (for example, communicable diseases, gunshot and knife wounds). Ethical practices are less well defined for the vast array of disclosures to secondary users -- such as managed care evaluators, insurance companies, and professional review bodies -- who by constraints of law, custom or contractual arrangement are entitled to review patient records.

Professional organizations continue to grapple with the evolving parameters of privacy and confidentiality in this new world. So do institutional accreditation organizations, such as the Joint Commission on the Accreditation of Healthcare Organizations (JCAHO) and the National Committee on Quality Assurance (NCQA). Federal legislation like HIPAA, and the state data protection laws with which it coexists, set some of the norms of information handling in new ways as well.
