    Area of Science:

    • Health Informatics
    • Telecommunications Technology
    • Information Systems

    Background:

    • Viewdata systems provide public access to computer databases using adapted televisions and telephone lines.
    • The high cost for information providers and limited utility of current Viewdata systems, such as Prestel in Britain, raise questions about their economic viability.
    • The potential application of Viewdata technology within the healthcare sector warrants investigation.

    Purpose of the Study:

    • To evaluate the relevance and cost-effectiveness of Viewdata systems, specifically Prestel, for the British health service.
    • To analyze the findings of recent experiments concerning the use of Viewdata in healthcare settings.

    Main Methods:

    • The study examines the existing literature and case studies on Viewdata system implementation.

    Related Experiment Videos

  • It analyzes cost-benefit data associated with information provision on Viewdata platforms.
  • The research incorporates findings from recent experimental trials within the health service.

    • Main Results:

    • Viewdata systems, despite technological capabilities, present significant financial burdens for information providers.
    • The practical utility and widespread adoption within the health service remain limited due to cost and usage constraints.
    • Experimental data suggests specific, albeit niche, applications may exist but require further validation.

    Conclusions:

    • The current high cost and limited demonstrated utility of Viewdata systems like Prestel challenge their broad relevance for the health service.
    • Further research and development are needed to ascertain if cost-effective and impactful applications can be achieved in healthcare.
    • The economic feasibility for widespread health service adoption is questionable without significant changes in cost structure or demonstrable value.
