One suggestion to add to this is with the potential commissioning and provision of medical services, to help cut out administration and any intermediate services. For example, in Radiology, the doctor could bid for services and if successful at 'auction' could then use their DAC viewer to upload and access decrypted MRI scan images. Quality control could be enhanced with feedback reporting systems, and with an automatic "second opinion" report provided by another doctor in a percentage of cases to monitor inter-rater reliability. Inter-rater reliability might be less biased as a feedback measure here. Initially, such a system could be used in training Radiologists, later pattern recognition systems could evolve to speed up processing and handling of many reports.
