HIT Platform™ is the only platform-as-a-service that incorporates Role-based Workflow, a patented NIST invention that grants situational (need to know) access to medical records and system functions, as an alternative to overly broad access to medical records. In certain situations, Role-based Workflow can provide order-of-magnitude improvements in patient privacy.
Instead of giving a healthcare worker 24×7 access to thousands of records under the assumption that they have broad authorization, this system gives that same healthcare worker momentary access to a single record or set of records that are relevant only to the case at hand. It preserves productivity and time-saving while protecting against abuse.
Virtual Global has engineered Role-based Workflow into a web services library, which is integrated into HIT Platform™. Role-based Workflow is available separately for integration into your own software systems.
