BlockChain in HealthCare industry

The Blockchain and its applications may still seem far away. Several cases of use can be envisaged in the health sector,  and many research have been, started years ago. 

                                            

Blockchain could be used for drug traceability, health data security, but the most impacting application on the daily life of patients and healthcare professionals could concern the management of medical data. 

Each patient could thus parameterize his or her medical record in such a way as to allow access (total or partial) to the persons of his choice (family, doctors, attending physician,  ...). 

By subsequently recording the stages of the care path in a blockchain grouping together healthcare institutions and insurers, it would also be possible to automate the payment of the necessary medical services, thanks to smart contracts.

With a longer-term view, it would even be conceivable that patients could anonymously monetize their data with the pharmaceutical industries, enabling them to study the results of their treatments on a wider population.

                                                            

This are such ideas that I've read on different actors in health industry. I really think this is future!! What do you think about??
