How Blockchain Helps in Securing Medical Records

The Basics of Blockchain Security

Blockchain technology is a network setup that produces data structures with inherent high-security qualities. It's based on principles of cryptography, decentralization, and consensus, which ensure trustless transactions. The data is preserved in blocks, and each block contains a transaction or bundle. Each new block becomes connected to all the blocks before it in a cryptographic chain so that it's nearly impossible to tamper with. All transactions within the blocks are validated and agreed upon by a consensus mechanism, ensuring that each transaction is true and correct.

Preserving the data and records of patients is necessary but challenging in healthcare facilities. It causes a lot of difficulties not only for the health organizations and hospitals but also for individual patients. Blockchain technology helps to collect the necessary data and records needed for further administration of patient care. Blockchain technology enables decentralization through the participation of users across a distributed network. With blockchain, there is no single point of failure, and a single user cannot change the record of transactions. Blockchain security is made possible through a special field in mathematics known as cryptography. The target for creating a new block is cryptographically defined, and once that is solved, an immutable block is mined. In the case of a blockchain for healthcare, this block should contain patient data. In this article, we will talk about how blockchain helps secure medical records from the point of view of a blockchain development firm with a team of blockchain development experts working to build the best blockchain solutions daily.

Blockchain Technology Applications in Healthcare

Using the Bitcoin SV blockchain, HER (Electronic Health Records) data is enhancing the world's first global HER, enabling individuals to securely own, earn and control the money from their personal medical information while furnishing health care providers and researchers with better real-time access to data. Although many clinicians use the terms EHR (Electronic Health Records) and EMR interchangeably, the advantages they offer greatly nowadays. An EMR is a recently introduced digital version of a chart with patient information stored in a computer, and an EHR is a digital record of health information. So while information can be stored digitally on servers and in the cloud, the blockchain offers a different infrastructure for preserving data.

Problems with Existing Electronic Medical Records

While visiting doctors, we can see that doctors only look for a notebook or a folder with our name. If you found yourself going to the doctors frequently, your folder would probably be filled up with different pieces of paper, making it look frighteningly full, but what about others who are not visiting frequently?

When you were young, you probably remember walking past this immense collection of files as you made your way to see the doctor and thinking two things:

How do they find your small file in such a huge number of information that all looks the same to me? What may happen if there is a fire incident or an accident where all these records got destroyed?

The second thought, scared perhaps scared you a little, comes next. Would this mean you would have to have all those horrible injections all over again because they were not sure what you already had and hadn't?

The advent of the personal computer saw governments worldwide determined to create EMRs to replace all of our dusty old paper records. The problem with electronic medical records, however, is that while they reduce the bulkiness of physical records, they are still vulnerable to attacks like DDoS that can take down years of records in an unbelievably short time. Users of these systems are also at risk of losing their personally identifiable information to malicious hackers.

Blockchain as the Ultimate Solution in Deep Medicine

Blockchain can secure any kind of document and verify personal, legal, and business documents—wills, trusts, patents, contracts, marriage certificates, death certificates, anything. When healthcare data for a particular patient is created, a new block is instantiated and distributed to all nodes in the blockchain network for patient data. This allows us to achieve a global view of the patient's medical history in an efficient, verifiable, and permanent way. Blockchain-based EMR would help doctors and nurses control the flow of information. Everyone can get the same data, and all updates are visible to the whole network. It means that doctors can trust that what they know about a patient is accurate.

A system like this could be implemented in many hospitals and doctors' offices worldwide so that they can get the same information. Mobile phones and similar types of devices have the ability to look after an individual's personal information and be an access point for both inputting and retrieving important data. So, it will reduce the probability of ill-treatment by any doctor as he can see the individual patient's previous medical history.

What are the Benefits of Blockchain In Healthcare?

Simplified Approach to Data Collection

Unlike a traditional way of getting information, healthcare records and data can be shared across multiple nodes using the healthcare blockchain worldwide. The need for storing data in various databases could be removed, hence, enabling the simplified approach to access the information required at any time.

System Interoperability

The inability to exchange medical records could lead to a delay in getting the treatment where blockchain could easily alleviate this problem by decentralizing the data. Everyone within the healthcare network could access a transparent yet immutable ledger while having data ownership.

Efficiency

Healthcare blockchain could make the system highly efficient via real-time processing and providing the necessary data. It can remove the need for third-party companies, eradicating the delays in accessing the data.

Control Over the Recorded Data

Anyone willing to access the health records will require the patient's public key. Patients can seamlessly control who should access what data. Since the data is saved in an encrypted form, it remains unreadable to hackers.

As the platform maintains complete and updated patient health information, it has facilitated prescription drugs and opioid abuse control.

Patientory

Patientory's blockchain platform securely stores and transfers medical information in Atlanta, Georgia. It supports end-to-end encryption, ensuring the safe sharing of all patient data. It enables patients and providers to access, store, and transfer all critical information via blockchain.

Blockchain Use Cases in Healthcare During the COVID-19 Pandemic

Because of the technology's capacity to allow better data consistency and authentication, the biggest advantages provided by blockchain are correlated with greater privacy. Blockchain can change the ownership and control of data from one centralized source to various data-contributing sources at the simplest level. These are a few examples of blockchain use in healthcare linked to COVID-19.

Contact Tracing

Many governments have embarked on contact tracing to follow the possible transmission of the novel coronavirus, in which infected individuals are asked to identify any other persons they have come into contact with. Data decentralization helps to promote vital healthcare operations, such as contact tracking, since the mechanism relies on the use of granular, confidential data to notify public health officials who, based on their activities and connections, may be at risk of exposure. Holding the privacy of people is important in contract tracing.

Patient Record Sharing

The collection of patient information during a crisis or catastrophe to build a "light" electronic health record system is another useful use case for blockchain when it applies to COVID-19, which groups of clinicians can use to exchange patient records when treating new patients during pandemics or other emergencies and natural disasters. Such a platform will allow providers to collaborate with patients who are unable to reach their regular providers but who still receive the full spectrum of care and medications required. The key principle of the approach is that patients' electronic health records accompany them wherever they go.

Clinical Trial Management

As it becomes usable, blockchain technology can assist researchers and clinicians in capturing clinical data in real-time. This increases precision facilitates data exchange, and maintains compliance with regulations. It can also monitor and keep track of who has accessed which portion of the datasets, providing an audit trail that enhances data protection and privacy. Civitas, an app introduced by a Canadian setup that is engaged in blockchain solutions, helps to monitor the outbreak of COVID-19 by different government officials and local authorities. It can discover whether or not a person has left his house. This is important because it helps to minimize the spread of this virus. Moreover, it will help doctors to track their patients' progress and evaluate their symptoms for any side effects.

Medical Supply Chain

The COVID-19 emergency disrupted supply networks around the world. Therefore, during the COVID-19 pandemic, many blockchain arrangements were in supply chain management. Blockchain accelerates the validation method by expelling third-party delegates and innate delays in managing and processing processes. The benefits include quicker time to manage and process, lower costs, lower operating risks, and faster settlements for all parties involved. All activities related to the manufacture of vaccines are noted and held in assigned ledgers, from codes to packages and materials.

Donation Tracking

The pandemic condition has offered mankind extreme hardships. The promotion of donation activities helps to assist people who face medical or economic challenges due to the spread of infectious diseases. In the donation process for affected people, this site serves as a platform for governments and healthcare organizations. The network ensures that the process of donation remains unchanged, reliable, and traceable. It offers a straightforward forum for donors to track where their funds have been used.

Outbreak Tracking

As information managed via such a network is secure, tamper-free, and transparent, blockchain technology offers an appropriate coronavirus tracking platform. All the data related to the pandemic can be preserved here, and those can be used at the right time at the right place when it is deemed necessary.
