LibreHealth EHR is an open source, clinically focused EHR which was designed for easy use and customizable for variety of settings. LibreHealth is a community that works to develop and implement Health Information Technology application to deliver better health outcomes using these technology platforms one among them being the LibreHealth HER. This is an open source, clinically focused EHR which was designed for easy use and customizable for variety of settings. The back end of this EHR is forked from OpenEMR data model. To move away from OpenEMR data storage, efficient reading and writing clinical data and improving interoperability, we need to move to the standard of FHIR (Fast Healthcare Interoperability Resources) Specification. This project aims to build components for LibreHealth EHR based on FHIR with Polymer components. This will enable the EHR developers to upgrade to a standard data model. The resources from modules in level3 and level4 of FHIR with maturity level above 3 will be developed using Polymer components. These resources were specifically selected as they contribute to the patient centric feature of the EHR.
