Visionair- Deliverables
1. Conceptual model (Month 12)– The conceptual modelling of a £1000 scanner for use in primary
care
– Development of associated services to support the end user
2. Demonstrator (Month 32)– Realisation of a demonstrator for virtual and physical assessment
– Realisation of a maintenance program
3. User evaluation (Month 42)– Research visualisation-related ergonomics and usage in the
context of the £1000 scanner
– Assess the social impact of the scanner in the appropriate domains

Observations
For a Procedure Lasting 20 minutes:
– Patient travels 24 Miles (typical)
– 18 Service Point Contacts
– 17 Days to Complete from Initial to Final Consultation (non emergency)
Source: Data supplied by sample of Bedfordshire GPs

Business Models
GP completes the Scan
Radiographer visits the surgery
each week
Radiologist visits the surgery each
week
Mobile Radiographer
Benefits
• Lowest cost• Lowest patient
journey• Outsource to
two resources
• Outsource to one resource only
• Quick process
• Maximum patient convenience (adapted for patient with limited mobility)
Operational Issues
• GPs’ training
• Radiologist required to complete analysis
• High cost of resource
• Higher cost• Lower
utilization of radiographer time
• Validation with GPs at three surgeries in the UK

Validation of the visualization tools
Strengths Areas for improvement
• Easily upgradable• Intuitive
• No quantitative data
Strengths Areas for improvement
• High level of explanation for non experts
• Interactions between objects and processes
• Appearance is not user friendly
• Configuration of Vivid
OPM Model
Vivid OPM
Slide 23 / 26

Application OPM: Multi-touch table
• Facilitating implementation of OPM business models (e.g. radiologist and radiographer communicate)
• Linking the iPads with the surface table, where the surface table and the projector could be the central assessment station.
• Application of Mind-Meister facilitating dynamic communication– Ability to share ultrasound images
– Ability to share OPM images
– Ability to also connect to iPad’s
to enhance mobility

Conclusions
• Visualisation has a key role in improving the design and delivery of healthcare
• OPM helped to conceptualise the detailed level drivers for business models
• Vivid OPM offers further opportunities to visualise conceptual models
• Validation results show that the findings are suitable and visualisation helps in many ways
