VueCentric vs CareWeb Framework• Same

– Extensible via plugin architecture– Context management– Event pub/sub with local/remote delivery– Composable user interface (design mode)

• VueCentric– Thick client– Proprietary deployment– Proprietary depnd management– Window only– Delphi (COM / ActiveX)– Metadata separate

• CareWeb Framework – Web app– Browser-based deployment– Maven– Windows, Linux, OSX– Java / JavaScript / HTML– Metadata bundled

CareWeb Framework is not just for VistA

• Regenstrief Medical Record System (RMRS)– Oracle/Postgres

• OpenMRS– MySQL

• VistA/RPMS– FileMan

• Any FHIR-compliant EMR (future)

Current Development Work

• VA Innovation Project– Demonstrate use of CareWeb Framework in a VistA/RPMS

environment.– Demonstrate port of selected RPMS-EHR components to

CWF (MU focus)• Immunizations• Chief Complaint• Patient Goals• Family History• Clinical Reconciliation Tool (Allergies, Problems, Meds)

Current Development Work

• NETSERV Network Services– TCP Connection and I/O Management– RPC Broker

• Async RPC calls• Event propagation

– Web Services• Restful FHIR endpoint• Basic and OAuth2 authentication

Current Development Work

• Serialization Framework– FHIR resources (patient, encounter, etc.)– Non-FHIR resources (user, parameter definitions)

Current Development Work

• Clinical Abstraction Layer– FHIR-based plugins– EHR platform agnostic– Truly interoperable plugins

Current Development Work

• ZK Sandbox– For prototyping and testing of UI layouts.– Test layout designs without restarting web service with

each change.– Better than existing tools (ZKFiddle, ZKSandbox, ZK Eclipse

plugin)
