Why Idea HePaaS

Leveraging The Valuable Data That Enterprises Have To Build Compelling Products And Insights Is Key To The Success Of Any Organization.

It is vital for every organization to leverage its valuable data to build compelling products and insights. In the case of Healthcare organizations, data is all the more  available from in-house sources like EHRs, patient  portals, payer systems and more recently medical  devices and wearables.
‍
With the availability of such rich and diverse data,  the complexity of managing it also increases  exponentially . Every healthcare enterprise is  diverting a lot of its effort to build the horizontal components necessary to manage this data, while  they actually should be focusing on developing the business use cases
specific to them.
‍
HePaaS is our solution to this problem statement. We  have abstracted all the functionalities required by an  enterprise grade Healthcare data platform and built it into our HePaaS. This enables our customers to  marshal their data and develop interesting business  use cases.



Healthcare-specific Complexities

Compliance
Healthcare organizations need to meet stringent  requirements pertaining to HIPAA, 21CFR, Meaningful Use given that they handle very sensitive ePHI information.
Security
There is a need for high grade security (SOC2 compliance) as PII data is involved.
Data standards
Healthcare data standards (HL7, FHIR) ensure interoperability, but variations persist. Advanced mapping and auto-configuration are essential for consistency.
