NHIN Direct Demo at Redwood Mednet HIE Conference
This wiki page is an archive of the Direct Project Demo at the Redwood Mednet HIE Conference on July 9, 2010 in Santa Rosa, California.
Goals:
The goals of the demo are to demonstrate the following:
- Enable providers with various technology choices that promote electronic health information exchange.
- Demonstrate technology choices and options that "meet the providers where they are" -- in other words technologies that enable optimal alignment with and incremental improvement of providers' business processes.
- Demonstrate Structural Interoperability among the providers by using common Content packaging.
- Demonstrate HISP services that enable secure health IT messaging.
- Investigate potential configurations for HISP in a Box

Demo Context:
The demo participants, the network topology, the backbone protocol, the different edge protocols and the demonstration scenarios that will be presented are described in the diagram below. (Note, see also Direct Project Convergence Proposal for additional details on the various protocols and HISP services).
Scenario:
The demonstration utilizes three HISPs: Redwood MedNet (RWMN), Santa Cruz HIE (SCHIE) and Western Health Information Network (WHIN, aka Long Beach). In the scenario each participant originates one Direct Project push message. For "bonus points" the Santa Cruz HISP uses a cc of their Direct Project message as an exported CCR to the patient's PHR.

DIRECT PROJECT SERVICES
Long Beach HISP
1. Based on the MedPlus REST prototype code within Quest Diagnostics Care360 web service
2. Enabled a Care360 user to browse and select clinical content from the patient clinical data repository, to assemble the content on the fly into a plain vanilla clinical summary pdf, and then to push that content to a user-entered Direct Project address
3. Due to time and resource constraints, only the REST send capability from Care360 was tested, with no inbound message service
Redwood MedNet HISP
1. Based on the CONNECT gateway SOAP service called from MirthResults clinical messaging application
2. Enabled a MirthResults portal user to view incoming Direct Project messages, and to compose outbound Direct Project messages, where MirthResults is the portal front end to a CONNECT gateway
3. MirthResults received incoming Direct Project SMTP messages at health internet address rm@nhin1.rwmn.org, the Redwood MedNet test environment
4. MirthResults sent outgoing Direct Project SMTP messages
Santa Cruz HISP
1. Microsoft Direct Project SMTP gateway service
2. Outlook received Direct Project SMTP messages from MirthResults
3. Outlook sent Direct Project SMTP messages
4. Able to cc a Direct Project message to patient's PHR account
DEMO AT CONFERENCE
Scheduled 3:10 PM to 3:30 PM (actual demo ran from 3:20 to 3:45)

WILL ROSS
Introduction to the technology context of this Direct Project bench demonstration. High level overview of the role of Direct Project push messaging as a workflow-appropriate adoption accelerator for health data interoperability services within the larger context of the Nationwide Health Information Network services and the ARRA framework of Meaningful Use measures. Reinforcement of Direct Project messaging as a complementary toolkit to other interoperability efforts, and its important heritage in the pursuit of "simple interop" as a technology breakthrough or tipping point.
Introduction of the organizations contributing staff time to this demo: Redwood MedNet, Santa Cruz HIE, Western Health Information Network, MedPlus, Mirth Corporation, Harris Corporation and Microsoft.

Recognition that this Direct Project workbench demonstration is intended to illustrate capabilities. This is not a reference implementation; those are planned for the fourth quarter of 2010.
MIKE HOGARTH, MD
Introduction to the clinical scenario in this Direct Project demonstration. Gordon Fakepatient is a 72 year old retired banker and resident of Mendocino with a history of COPD, coronary artery disease, and hypertension. Because of his complex medical problems, Mr. Fakepatient subscribes to a PHR service, and diligently keeps his PHR updated. After each office visit his primary care physician (Dr. R.M.) forwards a patient summary CCD to Mr. Fakepatient's PHR.

LAURA LANDRY (Dr. L.B.)
Mr. Fakepatient was visiting his daughter in Long Beach, California. One morning he had onset of chest pain and shortness of breath. 911 was called and he was transported to Long Beach Memorial Hospital in stable condition with persistent chest pain and elevated blood pressure of 200/105. His initial ECG showed tachycardia of 100, LVH, and lateral T-wave inversions. Cardiac markers were negative twice over several hours and his chest Xray was unrevealing. Mr. Fakepatient volunteered that last week he had some right leg swelling. Dr. L.B. obtained a CT angiogram which showed a medium sized right pulmonary embolism. He was admitted for further treatment of his PE and his poorly controlled hypertension.
During his hospital stay, Mr. Fakepatient is started on low molecular weight heparin for his acute PE. The next day Coumadin is also started. Over the next two days, his blood pressure improves with adjustments to his blood pressure medication. He is discharged on Tinzaparin 12,000 Units daily and Coumadin 2.5mg per day. He is instructed to follow up with his primary care physician in Mendocino, who will assume management of his anti-coagulation. On discharge Dr. L.B. forwards a care summary document, including the serial daily INRs and Coumadin doses given while he was in the hospital, to Dr. R.M., the primary care physician in Mendocino for Mr. Fakepatient.

Dr. R.M. continues Mr. Fakepatient on tinzaparin while adjusting the Coumadin. After several days, the tinzaparin is discontinued once he has been therapeutic on Coumadin. The plan is to treat Mr. Fakepatient with Coumadin for 6 months. Dr. R.M. forwards an updated patient summary CCD to Mr. Fakepatient's PHR, including a current medication summary and treatment plan.
Two months later, while visiting his brother in Santa Cruz, Mr. Fakepatient experiences significant back pain. He recalls helping his brother move a refrigerator into the garage the day prior. Mr. Fakepatient has a history of chronic back pain. A five hour drive away from his primary care provider, Mr. Fakepatient presents that morning at the Steamers Lane Urgent Care in Santa Cruz. During patient check in, Mr. Fakepatient is given the Direct Project address of Dr. Bob at Steamers Lane clinic as an optional part of the new patient clipboard process. He then phones Dr. R.M.'s office in Mendocino and asks for an encounter summary to be sent as a Direct Project message to Dr. Bob at Steamers Lane Urgent Care in Santa Cruz.

After a physical exam is negative except for significant back spasms, Dr. Bob, the urgent care physician, decides to recommend three days of valium with 600mg of Motrin three times a day along with bed rest until the pain improves. However, reviewing Mr. Fakepatient's medication list Dr. Bob notes that Mr. Fakepatient is on Coumadin, so and forgoes the Motrin in favor of Tylenol. Dr. Bob recommends that Mr. Fakepatient see his primary care provider in Mendocino for an INR and follow up visit within four days. Dr. Bob forwards an encounter summary to Dr. R.M. in Mendocino, with a cc to Mr. Fakepatient's PHR.

Four days later Dr. R.M. sees Mr. Fakepatient in Mendocino, who reviews his recent treatment. The INR is stable and his back pain is now largely resolved. Mr. Fakepatient is removed from valium and tylenol, and continues his usual coumadin dose. He will see Dr. R.M. in a month. Br. R.M. forwards an encounter summary to Mr. Fakepatient's PHR.
Sean closes presentation by contextualizing what we have done: a bench demo with newly developed prototype security tools to secure a federated SMTP backbone, with the demonstration of all three protocols in the current Direct Project production pipeline: REST, SOAP and SMTP. And that this was all put together in four weeks.
