Electronic Medical Prescription

Recently I've been reading a lot on programs started to achieve the possibility of Electronic Prescription (EP) in medical environments. It's interesting how something technically so near and available may take a lot of time to reach us. Technically an EP is just an electronic document signed and digitally processed... and its that complicate.
First of all we are talking about an issue that has had a lot of discussion around it: Medical Information. From a lot of time ago Medical Information and the Medical Record is one of the most zelously kept tresures. Laws are really tough in what can you do even with your own Medical Record. It's understandable then that EP has a lot to overcome on Personal Data Management Policys.
Because that, recently have been a bit of polemics around it. I'm sure finally we all will take with us our medical information, if not because it can save our lives, simply because it will be easy and secure enough to assure our compromised information will not be revealed to we don't want to.
