Overview of EHR.Network

EHR.Network enables development of healthcare applications compliant to Indian regulatory, standards, security and privacy requirements.

The infographics above represents a clinical information ecosystem. A large number of inter-connected components in the inner circles drive the functionality provided by the healthcare applications in the outermost circle segment.

To develop and roll out applications to respective target markets, application developers have to leverage many of the components in the above ecosystem and also ensure security of data, access control and also comply with patient consent directives.

The integration between the user interface of the application and the backend services are best done using REST. Indian EHR standards recommend FHIR for exchange of data and openEHR as the clinical modelling standards for building the repository of EHR data.

The data created and managed by the application if computable would make interpretation, analysis and research possible. Computable data needs to be coded using terminology standards - SNOMED-CT1, ICD-102 and LOINC3 are the applicable standards. A Drug database that provides generic and branded drugs applicable in India is required. NRCES in India releases India specific terminology datasets for use within the country.

All applications have to address requirements to store Clinical Information, Demographics Information and an Authorization to ensure security of information. EHR.Network separates the Clinical Information and Demographic information to safeguard the identity of patients in the event of data breach. The data persistence core is federated into Clinical Data, Registries that contain demographic information and Auth Mapping for secure access.
