Hi everyone! This this is the topic for general Connectathon discussion this weekend in San Diego. Feel free to use specific topic threads too if you want.

I look forward to seeing everyone this weekend!

You can add your name and CDS Service endpoint.

Thanks everyone who was able to come out to the Connectathon this weekend!

We have several participants acting as EHRs that would love to integrate with those of you who have brought CDS Services -- especially to test our proposed security model. If you haven't already, please talk with the folks from athenahealth, Cerner, Epic, and T-System to integrate your CDS Services.

Also, we have both the FHIR access token and JWT working in the open source CDS Hooks Sandbox. Please talk with @Zach Plata to see a demo of how that works

Kevin Shekleton (Sep 09 2017 at 17:31):

We are also planning a breakout session today to talk about some various topics. Stay tuned on the time, location, and topics later on!

For testing with JWTs, here is the public key for the open source CDS Hooks Sandbox:

what algorithm is used for your public keys?

Zach Plata (Sep 09 2017 at 18:22):

For the Sandbox and Cerner, ES256

Dave Carlson (Sep 09 2017 at 18:23):

As follow-on to Kevin's request for CDS Service implementers, I would like to identify and test STU-3 CDS Hooks services as part of the Care Plan track this weekend. Mostly patient-view hook at this point. I've had very good experience testing integration with @Brett Esler 's CDS service for GP preventative care guidelines and will continue integration testing with that. But would like to test others, if available. Thanks!

Robert Sax (Sep 09 2017 at 18:25):

did you use any specific client id?

brian doolittle (Sep 09 2017 at 18:27):

athenahealth is using RS256

Zach Plata (Sep 09 2017 at 18:47):

@Robert Sax Client ID for the Sandbox: 48163c5e-88b5-4cb3-92d3-23b800caa927

Kevin Shekleton (Sep 09 2017 at 20:14):

Reminder - we have a CDS Hooks breakout at 2pm in Palatine A to discuss various issues. The Palatine A room is to the left of the ballroom (if you're looking towards the front) and across the hallway

Kevin Shekleton (Sep 09 2017 at 20:15):

I'll be taking notes and writing up a summary of all discussions during this time so if you can't make the breakout, we'll have you covered later with notes!

After learning what CDS hooks are today (thanks for the explanations) I have a toy service up https://morning-mesa-37533.herokuapp.com/cds-services. It's pretty useless (patient horoscope... haha) but at least requires some prefetching and parsing of patient data. I am a big fan of this setup!

Martin Tran (Sep 10 2017 at 00:12):

I have a service running at https://evolveddev1.azurewebsites.net/cds-services. It's pretty basic at the moment, but please try it out! I'm planning to add JWT security.

Kevin Shekleton (Sep 10 2017 at 16:27):

Hi everyone and welcome to our final day (morning really) of the Connectathon! I think the work between everyone was great yesterday -- I saw a lot of activity between all of the participants spread across our 5 (!!) tables.

The breakout discussion we had was also very good and I'm pleased with the feedback, topics that we discussed, and the resulting issues were generated. I'll have a write-up summarizing the weekend as well as issue updates based upon our discussion later today.

Regarding the security discussion (and major focus of our work this weekend), I wanted to draw everyone's attention to the JWT changes. You can read a summary of these changes here. Additionally, I've updated the CDS Hooks documentation here with this change. The Cerner CDS Hooks Sandbox has already been updated to reflect the JWT changes. @Zach Plata is updating the open-source CDS Hooks Sandbox now with these changes and I'll let everyone know when that has been merged (should be in a few minutes)

Kevin Shekleton (Sep 10 2017 at 16:35):

I just confirmed the details of the Connectathon presentation later this morning.

Kevin Shekleton (Sep 10 2017 at 16:41):

The presentation starts at 11am and each track will get just 2 minutes to summarize their work. This is shorter than previous Connectathons (used to be 5 minutes) but necessary given the number of tracks.

Due to the very short time, I will only have time to hit the highlights from our work this weekend. I plan to cover:
- The record number of participants and organizations represented here (30!!!)
- Our great breakout discussion yesterday and the 1.0 release in 2017
- Our implementer feedback on the proposed security model
- New lab-order-create hook prototype from CDC

Please let me know if you feel like I should hit upon any other topics.

Kevin Shekleton (Sep 10 2017 at 16:42):

Also, I will be presenting the CDS Hooks Connectathon recap first so it will be right at 11am :-)

The stanson endpoint is being hit with a request using the fhir server 'http://fhirtest.uhn.ca/baseDstu3'. This request is being rejected because the server is not secure (https)
