Patient data platform and AI-enabled clinical decision support

The Business Challenge

A regional healthcare network with 12 hospitals and 200+ clinics operated fragmented EHR systems preventing coordinated care. Clinicians lacked unified patient views, duplicate tests were common, and interoperability with external providers was minimal. Rising costs and quality concerns demanded transformation.

Key Issues

  • 1
    4 different EHR systems across the network
  • 2
    No unified patient record across facilities
  • 3
    Duplicate tests and procedures (estimated $18M annual waste)
  • 4
    Limited interoperability with external providers
  • 5
    Manual clinical workflows reducing clinician efficiency
  • 6
    Inability to leverage data for population health management

Strategic Architecture Approach

Implemented a unified patient data platform with HL7 FHIR interoperability, established AI-driven clinical decision support, and modernized patient engagement capabilities while maintaining HIPAA compliance and clinical safety standards.
