External System Integration

External system integration(HL7) – is a standard used to interface patient electronic medical report with external devices. It is to provide a standard for the exchange, management and integration of data that supports clinical patient care and the management, delivery and evaluation of health-care services. Specifically, to create flexible, cost effective approaches, standards, guidelines, methodologies and related services for interoperability between health information systems.

Features:

  1. Responds to the demands of the market, making it a standard health information system.
  2. Has a governance structure and a change process.
  3. Platform and technology independent standard.
  4. Enables information exchange between computer applications developed by different (often competing) vendors.
  5. Reduces paper work, improves decision-support and allows you to integrate health information over time and across health service delivery systems.
  6. Reduces short-term costs and project delivery time in: Analysis, Development and Implementation.
  7. Reduces the labour and time involved in negotiating application-to-application (or point-to-point) interfaces.
  8. Reduces the custom programming required in health application “interfacing” and program maintenance.
  9. Facilitates better patient care.
