Health Data Supply Chain Projects, 2005-2020

Connecting for Health Prototype NHIN Demonstration    JUNE 2005    Connecting for Health demonstrated simple electronic health data interoperability by remote search and retrieval of patient data among three independent sites. Each site, Massachusetts, Indianapolis, and Mendocino, was hosted on dissimilar technology platforms. Redwood MedNet, operating under a DBA as Mendocino Health Records Exchange, participated as the Mendocino site.

NHIN Prototype Architecture Project    NOVEMBER 2005 - JANUARY 2007    Under contract with the Office of the National Coordinator (ONC) four teams each built candidate multi-site prototypes to demonstrate scalable nationwide solutions for electronic health data interoperabilty. Redwood MedNet participated as the Mendocino HRE site on the Computer Sciences Corporation / Connecting for Health team.

Open Source Care Data Exchange / OpenEMPI    DECEMBER 2006 - APRIL 2007    Under contract with California HealthCare Foundation (CHCF) a team led by Redwood MedNet created a new explicitly open source fork from the legacy proprietary "Care Data Exchange" identity matching software previously developed for the large scale CHCF demonstration project known as the "Santa Barbara County Care Data Exchange." At the conclusion of the demonstration project Redwood MedNet named the new open source fork Open Enterprise Master Patient Index (OpenEMPI). An engineer who helped Redwood MedNet develop the open source demonstration then improved the OpenEMPI code into a formally developed and supported enterprise software package, which is still available today.

Hospital Lab Results > CDMS    FEBRUARY 2007 - DECEMBER 2007    Redwood MedNet built a real time outpatient laboratory test results delivery service from a hospital laboratory into a chronic disease management software (CDMS) package running at a Community Clinic (FQHC). This project was also the first production use by Redwood MedNet of the Mirth integration engine as a processing node in the delivery of electronic laboratory test results. In this instance, the Mirth software ran on a small form factor appliance.

ELINCS > EHR    OCTOBER 2008 - SEPTEMBER 2009    Outpatient test results from a hospital laboratory formatted in the ELINCS constrained file format was not able to be parsed by EHR. Part of the problem was that this EHR was unable to distinguish preliminary, final, or amended status for a test result. See and also Implementing the ELINCS Standard. The lab interface implementation was incomplete during the one year ELINCS demonstration project, but the failed lab results delivery project so annoyed the physician that he later received a software update from the EHR vendor that enabled incoming lab test results to behave correctly.
