ISO/TS 27790:2009 specifies a general purpose document registry framework for transmitting, storing and utilizing documents in clinical and personalized health environments. It is quite broad in its applicability to realise the goal of sharing health related documents spanning a broad spectrum of health domains such as healthcare specialities covering laboratory, cardiology, eye care, etc and the many areas of personalized health.
ISO/TS 27790:2009 also references a number of companion standards-based specifications that offer optional extensions to enhance the basic capabilities offered by IHE XDS. It references the support of the following.
- An XDS extension supporting the fragmentation of the content of the documents into two parts: a header fragment and a body fragment. This separation scheme enhances confidentiality because the gathering both of header and body and their relational information involves cracking into multiple repository servers. This has been developed as an IHE Korean Extension on the IHE XDS Profile.
- A series of security- and privacy-related IHE profiles, such as Patient Identification Cross-Referencing (PIX), Patient Demographics Query (PDQ), Basic Patient Privacy Consent (BPPC), Cross-Enterprise User Assertion (XUA).
