In my experience, one of the most significant hindrances has been access to and communication with medical personnel:

- Medics, especially specialists / surgeons, have extremely busy schedules, often holding down both public & private patient responsibilities as well as performing duties for their specific colleges etc.

- The level of IT-savvy amongst healthcare pros is generally low.

- They seem to have a different logic to us IT folk, answers are nebulous for non-medics and hard rules are very difficult to pin down. Ask the same question n times and you will get n different answers, from the same respondent.

When you find a medic who is willing / able to help and towards the positive on all the above axes, you must hold onto them with a death grip.
