A computer-based system in Maastricht provides general practitioners with feedback on test requesting. This effective system uses electronic data interchange and an expert system to screen requests, improving laboratory efficiency.

Area of Science:

  • Health Informatics
  • Clinical Decision Support
  • Laboratory Medicine

Background:

  • Screening general practitioner test requests is labor-intensive.
  • A project within the AIM programme OPENLABS aimed to automate this process.
  • Existing systems lacked efficient feedback mechanisms for test requesting behavior.

Purpose of the Study:

  • To design and implement a computer-based feedback system for general practitioners.
  • To improve the adequateness of test requesting behavior.
  • To reduce the workload associated with manual screening of laboratory tests.

Main Methods:

  • Development of electronic data interchange (EDI) messages for test requests, now a Dutch standard.
  • Integration of a laboratory decision support system with a database and an expert system.

  • Automated screening of test requests and patient data by the expert system.

    • Main Results:

    • The developed system effectively provides feedback on the adequateness of test requests.
    • Electronic data interchange (EDI) facilitates standardized communication between general practitioners and laboratories.
    • The computer-based system demonstrably improves test requesting behavior.

    Conclusions:

    • Computer-based feedback systems are effective in optimizing general practitioner test requesting.
    • Standardized electronic data interchange (EDI) is crucial for efficient laboratory information systems.
    • The Maastricht system serves as a model for improving laboratory test utilization and efficiency.
