Hi Velko, I am Michael, one of the founders of Aimedis and medical doctor. We're not using buzzwords and are not using the blockchain to distribute the database as putting information of the databases into the blockchain just doesn't make any sense. We're using the blockchain to make sure all of the transactions performed by patients, hospitals and doctors are 100% documented to prevent e.g. fraud when it comes to electronic prescriptions or right management settings decided by the patient. We're using smart contracts to execute e.g. certain legal and documentary step in case it comes to an emergency record access by a hospital or paramedic. If you're interested in more information and maybe even have some ideas as you seem to be a blockchain pro, we'd appreciate this very much.   
Kind regards
Michael
