This study presents a prototype search engine for accessing integrated virtual patient records across healthcare settings. The system ensures secure, authorized access to scattered medical information, improving longitudinal patient care.

Area of Science:

  • Health Informatics
  • Information Management
  • Computer Science

Background:

  • Patient information is often fragmented across various healthcare settings.
  • Integrated access to patient data is crucial for comprehensive longitudinal care.
  • Existing systems lack unified access and robust security for distributed medical records.

Purpose of the Study:

  • To develop a prototype search engine for integrated virtual patient records.
  • To implement authorization and access control for secure medical information retrieval.
  • To support longitudinal patient care activities within a health district intranet.

Main Methods:

  • Utilized the signature file access method for data retrieval.
  • Developed an experimental implementation using JAVA.
