what worked well 1. flexibility and reliability of DVTS system 2. good video and sound quality 3. acceptable time delay – ~ 2 sec 4. effectiveness of the interactions 5. excellent co-operativity and organisation
problems and solutions 1. network – work with network engineers • reliability - • time delay – shorter links • Firewalls – dedicated links • audio quality / standardising audio volumes security / patient confidentiality – need to 2. find VPNs that don’t degrade the image PAL versus NTSC – need compatible video 3. mixing systems
what next ? • local / national interest is strong, but needs developing • more links, better connections • how can we add value to the interactions • network protocol • more structured sessions • additional data / images / powerpoint • stop testing and start using – ‘mainstream’ the technology
what next ? medium term • linked curricula for education and research • live collaborative projects • disaster / pandemic management • linked databases, more integrated IT • public / population health • use of the technology across all sectors of medicine, including in developing countries
what next ? blue sky what next ? blue sky ? • 3-D • haptics • robotic surgery
