plug and play interoperability
Plug-and-Play Interoperability

WHY IT IS NEEDED:

  • Specialized applications / multiple vendors
  • Medical devices and clinical information systems
  • No time for configuration or set-up programs
plug and play interoperability1
Plug-and-Play Interoperability

FACTORS TO CONSIDER:

  • Safety
  • Unambiguous association
  • Reliability
  • HL7 Interoperability
  • Security
  • Scalability
