Has anyone? If we say HEART can't do that we're calling into<br>question the legitimacy of HEART.<br> - We have a lot of experience with 75-page CCDAs with the current<br>standards. Many patients have huge health records and it is<br>resource-intensive to get 74-pages of information you already had in order<br>to find the change from the last encounter. The cost is not just on the<br>sender but on the recipient as well. This is probably the top complaint of<br>the current interop methods in my medical society.<br> - I don't think the HEART charter set a particular limit on how much of<br>FHIR we would manage. It's not in our charter to treat effective<br>provider-to-provider exchange as out-of-scope. Once we say that HEART will<br>not support the full patient-level feature set of FHIR, where do we draw the<br>line?<br> - UMA is not OAuth. The goals of the two standards are very different.<br>UMA and HEART are patient-centered. If we restrict HEART to a small fraction<br>of the longitudinal health records or patient-centered health rerecords<br>transactions (because most of the traffic stays in the batch or<br>institution-to-institution domain) then where do we host the discussion on a<br>future for patient-centered records?<br> - There is no logical reason for HEART to not support date ranges once<br>FHIR has that capability. In some jurisdictions, this would be seen as<br>reducing patient's right of access and subject to legal challenge. <br><br>I've added Josh and Grahame to this thread.
