Those of us who participate in Cancer MDTMs recognise what a vital place it has had in the improvement of patient care. We also know that a multiple documents & images are displayed at MDTM. These images & documents are created & stored in multiple IT systems. However, a patient centric discussion is required. XDS standard would allow for a patient centric view of doc & images created & stored in multiple IT systems. I have written a basic clinical system specification for a MDTM Information Systems.
