One of the key advantages is the Step-by-step recording of information. In the chain of information, you can add a new element, but you can not delete the old one. More precisely, the algorithm of the Blockchain operation allows you (if you are a hacker) to locally change any data but to record the current operation, you will need to get confirmations of other computers (users) of the system about the integrity of the entire chain. This all happens in an automatic mode. If any element of the chain does not match the same element on another computer, the record operation is canceled. Thus, the whole chain must be complete. No one can change previously recorded information.
On the one hand, this gives a lot of advantages. The patient can always be sure that his information is protected and can not be changed by anyone. On the other hand, it needs very responsibly approaches to filling out the data. After all, a doctor can make a mistake and this can lead to an unpleasant situation in the future.
Another important feature of the Blockchain technology is its global access. The patient can easily provide access to the treating doctor. At the same time, a doctor can get data from anywhere in the world.
Integration of Blockchain Technology in Healthcare
Electronic health records (EHR)
Blockchain is great for creating a single patient registry (Electronic health records). In fact, there will be a single base with a high level of security, stable operation and access from anywhere. Having such an infrastructure, the patient does not need to worry about data synchronization. Any doctor can review the medical history and prescribe treatment, of course only after the patient's permission. All data will be recorded in the general register, regardless of whether it is a private reception or health insurance application.
After all, often, a private doctor's appointment is not displayed anywhere in the patient's history. This will make it possible to see a clearer picture of the patient's illnesses. Our company, Merehead, is developing a web application in the healthcare, the interaction of doctors and patients. And we believe that this is what is missing in the healthcare industry - the consolidation of patient data in one place based on reliable distributed technology.
This approach will significantly reduce the cost of hardware clinics. The data will be updated in real time, and the processing will be reduced several times. Within a few seconds, the doctor can find out blood group, chronic diseases, allergic reactions, etc. Thus, there is no need to do repeated tests. This will save time and increase the speed of treatment.
But there is a problem, the standardization of data. It is very important that all data is stored in one format and not lead to confusion. In addition, all information should be recorded according to pre-established standards. It may take several years. The data must be reliable and confirmed by the patient himself. Another problem is the reliability of the diagnosis. A wrong diagnosis can lead to wrong treatment. This will be displayed in the lisy of Electronic health records and may affect the following doctors decisions.
Everyone knows the problem of counterfeit products. Blockchain can solve this issue. Each transaction between the manufacturer and the distributor can be recorded in a chain. Within a few seconds, the system will allow you to easily check the drugs for authenticity, learn the manufacturer and the history of the movement.
Using Blockchain technology, people can bring to single standard protocols and electronic health records. This will make it possible to move to a single international standard.
Blockchain future in healthcare
In the near future, IoT devices can collect patient data (pulse, pressure, temperature, etc.) and in real time and add to electronic health records. Data will be transmitted every second in 24/7 mode. The doctor can clearly know when the temperature or pressure has risen when the headaches began. This will allow to more accurately diagnose and prescribe treatment.
In general, Blockchain technology in medicine will allow clinics to work more efficiently with a lower cost. It opens up new opportunities and will lead to a revolution in the healthcare industry. Blockchain will allow raising patient services to a better level.
