Blockchain is a data structure technology that makes it possible to create a digital transaction ledger and share this within a distributed network of computers. Processes can be optimised in this way, and various supply chains (both internal and external) can be connected with each other.
Blockchain technology can provide added value in healthcare in four ways. It is a combination of these four elements that makes it unique in my opinion, since these issues could be solved individually using other technologies.
- Non-repudiation: nothing produced in the blockchain can be repudiated (its validity cannot be denied). Thanks to the decentralised database structure, uninvited users are not able to change the data.
- Control lies with the client: The patient or client manages the permission structure with respect to his or her data. He or she is in charge of his or her own data.
- One source of information for all: all users work together within the same authorised data source. At present, the healthcare industry consists largely of data silos. Connecting all these silos also enables the healthcare sector to create clear profiles, and to carry out better analyses.
- Administrative optimisation: the blockchain enables the user to perform real-time processes and administration. This means that fraud-sensitive steps can be avoided and administrative processes can be performed faster and automatically.
The blockchain is currently a hype, partly as a result of the Bitcoin world. With Ledger Leopard, we have shown that the technology really does work, and that it provides added value in areas including healthcare. There are currently few companies that have developed or implemented successful blockchain innovations. It is extremely difficult to get a blockchain concept off the ground successfully. This is due to various different elements.
Its implementation requires different parties to work together in a distributed network. It is important to clearly explain the advantages of the technology to all parties involved as this increases the feasibility of its implementation. Furthermore, the healthcare chain is undergoing a paradigm shift, and the mindset of the entire chain is subject to a transition. I regard managing the perception of patients and professionals as a holy grail in the implementation process. Finally, the technology will have to be improved with respect to transaction speed and data management functions. Structural solutions are needed in order to achieve this. To date, we have been working on blockchain applications for patient/client mobile phones.
Blockchain technology offers a concept with which healthcare can be organised differently. We will have to work towards this end step by step. Contrary to what some revolutionary thinkers believe, we are currently still only at step 1: being able to implement the technology. I expect to see the first major changes in existing processes within two years, after which the next step can be taken. In order to achieve this, parties such as healthcare insurers and banks must be prepared to accept their new role, and developments in legislation and regulations will also be required. Only from step 2 onwards will the blockchain have a groundbreaking impact on healthcare and change the way processes are operated. Patients/clients will, from that moment on, find themselves increasingly ‘in the driver’s seat’.
