More and more money allocated for health care is absorbed by administrative and control processes. The use of blockchain technology can reduce these costs and, as a result, release additional resources for the treatment of patients. Virtually all over the world, the administrative costs associated with the regulation of health care and insurance, the control of drug financing and diagnostic tests absorb the monstrous part of the costs that we theoretically pay to health care. What is the reason for this? Most likely, the system is too comprehensive, includes many stakeholders and, in addition, includes data processing, which is considered extremely time-consuming. So, maybe it's time to approach the problem from a completely different perspective.

Blockchain can change the whole health system

In the health care system, the central point is the patient identifier, which should be able to decide which confidential data about it can be accessed by medical institutions. However, this system also includes various other organizations:

1. Companies that pay contributions.

2. State and private insurance companies.

3. Medical facilities, doctors, pharmacists.

4. Manufacturers of medicines, operators of medical devices and many others.

The unambiguous identification of these persons and the resolution of the transactions concluded by them can be provided by a block chain. The current centralized approach does not have such a universal identifier, so the parties to the transaction create complex control mechanisms aimed at mutual trust. These mechanisms make the entire health system costly and inefficient. Since its inception, Blockchain has been working on the principle of code disclosure, which ensures that the code is transparent and can be developed by other organizations. Even the largest IT companies have decided to publish the results of their work in this area for the development community of blockboys.

Each patient paying for medical care will be able to register payment in the state register. Thanks to this, each medical institution will have the opportunity to check whether the payment was made on time and in the appropriate amount. In Blockchain, each registered transaction is unique and irreversible. It remains in the system forever without the possibility of subsequent modification. In addition, an indelible time stamp indicates when the transaction was made.

A virtual wallet can solve the problem of paying for medical services

An individual digital wallet to pay for medical services will automatically replace the electronic system to verify the right to receive the beneficiary, since the medical institution can check in the public registry when the last payment was made. Some employers pay additional medical assistance to their employees through bilateral agreements with private medical companies or additional health insurance. In addition, some employees pay individual contributions.

The problem of access to medical data will disappear

In addition to raising funds for medical care and marketing of drugs, the chain-lock system can store keys from medical data stored in different places, both stored in the text and in the image. Due to this, the doctor can access the individual results of medical examinations of the patient performed in another institution. This will reduce the need for repetition of costly medical tests and - through public registers - improve the monitoring of the use of diagnostic equipment in individual rooms.

First implementations

Using block chain in medicine is not just a futuristic look. In a number of countries, initiatives are being implemented to introduce blockage into the health care system. Estonia, which first began work on a Blockchain-based identification system (a solution that is different from the bitcoin support, but conceptually similar), boasts an electronic system of prescriptions and medical records of patients. These entries are protected by a block circuit. From the doctor's point of view, the patient's data are provided as if they were stored in one place. However, it is not. A system based on a chain of blocks allows you to only index this data and protect it from unauthorized access and modification. The data itself is stored in the places where the tests were performed and given to the patient on request or in a critical situation by a doctor acting on behalf of the patient.

A similar system of BL chain is tested in Dubai. Turkey also plans to use blockade in the healthcare system and to combat drug marketing. Philips and Gem in Philips Blockchain Lab are developing their own solutions related to the implementation of the blockade platform in the healthcare system. Of course, block chains can not be viewed as a panacea for problems with documenting medical events. For example, Blockchain is poorly suited for storing and retrieving large amounts of data, so it will never replace specialized and analytical systems. However, the block chain system is probably the only widely available solution to ensure interoperability and transaction synchronization between existing and newly created IT solutions without unnecessary transformation of data into a single format.

Since its inception Blockchain has been working on the principle of open source, which guarantees transparency of the code and can be developed by other objects.
