<p class="MsoNormal">Our goal is interoperability. I suggest we base our design pattern priorities on (a) the recent GAO report and (b) the doctors in my state medical society.

<p class="MsoNormal">"Stakeholders and initiative representatives GAO interviewed described five key challenges to achieving EHR interoperability, which are consistent with challenges described in past GAO work. Specifically, the challenges they described are
(1) insufficiencies in health data standards, (2) variation in state privacy rules, (3) accurately matching patients' health records, (4) costs associated with interoperability, and (5) the need for governance and trust among entities, such as agreements to
facilitate the sharing of information among all participants in an initiative."<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">(b)<br>
Two MA medical society resolutions and our Task Force (which Dr. Sullivan chairs) have all concluded that physicians need to have control over information sharing for their patients without what ONC calls "blocking" by the institutions or EHR vendors that may
be involved. Our Task Force has actually suggested to the AMA that physicians should have a way to get access to the patient-controlled EHR interface. This approach is sometimes referred to as patient-directed exchange. Note that patient-directed exchange
does not mean that the patient gets to see her own data (as with a patient-mediated or PHR exchange). The FHIR resource goes directly from the NPE to the Requesting Party. In this way, and with appropriate FHIR cooperation, this helps solve difficult provenance,
cache consistency, and patient matching issues. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Of the 5 GAO "challenges" (2), (3), and (5) would be completely eliminated by a patient-directed design pattern. (1), the data standards, is a combination of FHIR and HEART outcome. (4), costs, should be equivalent
for any FHIR API design pattern, but even if costs were an issue, the patient-directed exchange allows for patient pay to remove that barrier.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Choosing to deliver a patient-directed design pattern as our HEART baseline does not preclude either FHIR or HEART from delivering other design patterns in the future but it will inform the work of FHIR and
align our efforts with the GAO and physician comments.<o:p></o:p></p>

<p class="MsoNormal">For the individual-to-role pattern, HL7 has a role based access control standard. It includes and extensive vocabulary of healthcare roles, and it is extensible. This can be used to share access control role semantics across authorization
services. <br>
<br>
The individual-to-NPE and individual-to-role patterns presents some interesting challenges. One of them is that the mapping of access permissions depends on the location and work assignments. For example, health care staff may be assigned to different care
locations and have legitimate access only to the patients' data for that location. Similarly, the role assigned to a person will vary. I do not know how amenable these cases are to technical solutions. Current practice is to assume compliance of the staff
to institutional policies.<br>
<br>
What identifying data needs to be shared among users to access Alice's [current] authorizations? What is its provenance?

<p class="MsoNormal">The reason interop questions arise is because the process of UMA trust elevation involves things like claims-gathering and possibly step-up authentication, and the policy-setting options presented to Alice (which are out of band of UMA,
but nonetheless...) need to be driven by these requirements. The ability of the requesting sides to respond appropriately will be triggered off of expectations about what they'll be asked to cough up for trust elevation.<o:p></o:p></p>

The one I'm least enamored of is #3; enterprise access control has had so much trouble with RBAC, so can we expect adding UMA to help? :-)<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo2">
Chained delegation can be very powerful. In environments where everybody uses the same UMA authorization server, a number of nice value-add features can be supported, but they tend to break down (at least with UMA V1.0.x) when you add the ability for every
RO to choose their own AS.<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo2">
I worry about sharing with individual doctors. It's very expedient, so people will tend to do it as a path of least resistance (think Google Apps!). And sometimes maybe it's the right answer, particularly if "chained delegation" can allow Alice to track where
her resource has been shared further. But what if Dr. Bob leaves the hospital/practice/whatever? Is this always the right answer?<o:p></o:p></li><li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo2">
Sharing with an NPE sounds elegant -- it's what a recent POC of my acquaintance did. But the "process yet to be determined" mentioned above wasn't actually determined yet, so there's that. :-) And you have the problem of a system administrator who has privileged
identity credentials to the NPE account -- as always -- having the key to a pretty valuable kingdom. Maybe a cool mitigation of this risk is to go with sharing with individuals and tracking sharing chains?<o:p></o:p></li></ul>
