Health care transformation through collaboration on open-source informatics Projects: Integrating a medical applications platform,research data repository,and patient summarization

Background: the strategic health it advanced research projects (sharp) program seeks to conquer well-understood challenges in medical informatics through breakthrough research. two sharp centers have found alignment in their methodological needs: (1) members of the national center for cognitive informatics and decision-making (nccd) have developed knowledge bases to support problem-oriented summarizations of patient data,and (2) substitutable medical apps,reusable technologies (smart),which is a platform for reusable medical apps that can run on participating platforms connected to various electronic health records (ehr). combining the work of these two centers will ensure wide dissemination of new methods for synthesized views of patient data. informatics for integrating biology and the bedside (i2b2) is an nih-funded clinical research data repository platform in use at over 100 sites worldwide. by also working with a co-occurring initiative to smart-enabling i2b2,we can confidently write one app that can be used extremely broadly. objective: our goal was to facilitate development of intuitive,problem-oriented views of the patient record using nccd knowledge bases that would run in any ehr. to do this,we developed a collaboration between the two sharps and an nih center,i2b2. methods: first,we implemented collaborative tools to connect researchers at three institutions. next,we developed a patient summarization app using the smart platform and a previously validated nccd problem-medication linkage knowledge base derived from the national drug file-reference terminology (ndf-rt). finally,to smart-enable i2b2,we implemented two new web service cells that expose the smart application programming interface (api),and we made changes to the web interface of i2b2 to host a carousel of smart apps. results: we deployed our smart-based,ndf-rt-derived patient summarization app in this smart-i2b2 container. it displays a problem-oriented view of medications and presents a line-graph display of laboratory results. conclusions: this summarization app can be run in any ehr environment that either supports smart or runs smart-enabled i2b2. this i2b2 clinical bridge demonstrates a pathway for reusable app development that does not require ehr vendors to immediately adopt the smart api. apps can be developed in smart and run by clinicians in the i2b2 repository,reusing clinical data extracted from ehrs. this may encourage the adoption of smart by supporting smart app development until ehrs adopt the platform. it also allows a new variety of clinical smart apps,fueled by the broad aggregation of data types available in research repositories. the app (including its knowledge base) and smart-i2b2 are open-source and freely available for download.
