All patients have the right to privacy and the expectation that the confidentiality of their personal information will be rigorously maintained by all psychiatrists. As well as being medically necessary the protection of privacy and confidentiality is both an ethical obligation and a legal obligation. Nevertheless, they are not absolute obligations and must often be considered in the light of other obligations. In this chapter three categories of protections, uses and disclosures are each considered: protections, uses, and disclosures of patient information for their healthcare (Sect. 4.3.2); protections, uses, and disclosures of patient information for healthcare purposes not directly related to their healthcare (Sect. 4.3.3); and obligations and justifications for the disclosure of patient identifiable information for purposes not related to their healthcare (Sect. 4.3.4).
