Healthcare Blockchains Use Cases in
Digital Health
The blockchain technology first came to the spotlight as a
transaction ledger for the public in cryptocurrency bitcoin in 2008.
However, the idea of blockchain first came into the play as a
research project in 1991. With time, more people got aware about

blockchain technology. Its advantages, and applications in diverse
sectors.
Presently, the global blockchain industry is valued at over $7 billion
and is projected to reach 163.83 billion by 2029. While the growth
in blockchain technology usage and demand has resulted in high
market potential and growth scope, it is no longer limited to just the
finance sector but has become widespread.
Healthcare is one such sector which has been witnessing a
significant revolution with the introduction of blockchain technology
in digital health. But what is the exact use of blockchain technology
in healthcare? Or, what are healthcare blockchains or, the meaning
of crypto medical? In this blog we will cover it all along with the
basics on blockchain.
What is Blockchain Technology?
A blockchain is basically a type of database that is distributed
among the different nodes of a computer network and is used to
store information electronically. The blockchain technology is used
to collect information in groups that are called blocks and forms a
chain of data called blockchain.
This record-keeping technology comes with high security that
makes it impossible to change, hack, or forge data in the system.
Here the data stored inside the blocks may vary based on the type
of blockchain or blockchain technology used, and the relevant

sector it is used in. The main purpose of blockchain technology is
storing digital information securely without letting it get altered,
deleted, hacked, or compromised.
With the advent of advanced technical solutions, the usage of
blockchains is increasing exponentially around the world. For an
estimation, the global spending on blockchain is expected to grow
to nearly $19 billion by 2024 and crypto medical remains a
significant contributor to it. Before we delve deeper into how digital
health is transforming with healthcare blockchains, let's give an
overview on the importance of healthcare blockchains and their
relevance.

Importance of Healthcare Blockchains
There are several benefits of healthcare blockchains and here we
have listed out some of the top ones -
Decentralization
As previously stated, the Blockchain uses a decentralized
approach that makes it hack-proof and ensures that no one copy
of data is compromised. All of the hospital's commodity hardware
can be made to run on these decentralized systems. All man-made
and natural disasters will be eliminated, assuring complete
security.

Furthermore, researchers can use the power saved by these
devices to perform complex computations in order to develop
cures, medications, and therapies for a variety of diseases and
conditions.
Single Source of Data
Data plays a very vital role in the healthcare sector. Patient records,
their vitals, patient history, medicine dosage, and other related data
must be stored with high security. Healthcare blockchains are what
helps serve this purpose to store the crucial data in a single
source.Being completely secure from getting modified, deleted,
hacked or compromised, healthcare blockchains are often the first
choice for data storage and access in the healthcare sector.
24/7 Data Monitoring & Access
It is not unknown that continuous monitoring is a must-have criteria
in the healthcare sector when it comes to useful data. Starting from
the patients’ oxygen levels to their blood pressure readings - all
such crucial data need to be monitored 24/7 and accessed as and
when required. Traditional healthcare DBMS (Database
Management System) lacks one significant feature - impenetrable
security against being altered, deleted or hacked. Healthcare
blockchains solve this concern making the data monitoring &
access easy, fast, secure, and efficient in healthcare.
Strict Rules through Smart Contracts
Smart contracts are the programs stored on the blockchains and
are executed only when a predefined set of conditions and
protocols are met. Healthcare blockchains having this feature,

helps in maintaining strict healthcare rules and protocols when it
comes to accessing patients' healthcare related data or other
confidential information.

Use of Blockchain Technology in Healthcare
Now that you have a clear idea on the importance of healthcare
blockchains, let’s walk you through the use of blockchain
technology in healthcare.
1. Electronic Health Records (EHR)
The ideal scenario for Electronic Health Records is to keep a
permanent medical record that is accessible to all members of the
care team, including physicians, lab technicians, and others, at the
point of service and on time. Patient data is currently kept across
many organizations throughout the patient's lifespan in current
EHR deployments. Physicians record a few areas of a patient's
medical record, such as medication problems and diagnoses, and
they keep stewardship of those sections after the patient has been
treated. A patient owns the stewardship of a medical record in a
blockchain implementation, and clinicians will be granted access
on a need-to-know basis using "smart contracts."
One of the key challenges for EHRs is the accurate management
of records, which includes the repair of any incorrectly recorded

data. Apart from guaranteeing data integrity, diverse providers and
hospital systems confront interoperability issues, resulting in
ineffective, if any, data sharing. Health records are fragmented due
to a lack of cooperation in data management and exchange. And
undoubtedly, healthcare blockchains give a compact all-in-one
solution for all these making the electronic health record keeping
easier, secure and streamlined.
Smart contracts automate and track state transitions in a system,
such as viewership rights or new record production. Blockchain
records are cryptographically hashed to ensure data integrity. The
care team can add new records to a patient's profile, and the
patient can authorize which providers have access to the
information. This encourages patient and provider participation and
aids in the development of patient records. The blockchain design
is based on decentralization and cryptography concepts, which
could lead to more secure and interoperable EHR systems.

2. Clinical Research
While there has been significant progress in shifting medical data
from paper to digital records, the healthcare industry is still
grappling with difficulties related to patient data exchange across
providers and organizations. Patients may move locations, change
health insurance, and change healthcare providers for their
treatments at any time during their lifetimes. The majority of their
detailed medical records are kept in silos by each hospital or

provider. In addition, each medical entity would have saved patient
data using its own storage structure and semantics. This creates
roadblocks when it comes to data sharing. These roadblocks are in
place partially owing to the nature of the data in question (Protected
Health Information) and in order to avoid data blockage during
transmission.
This has ramifications not only for efficiently treating patients
across many organizations, but also for clinical research, which
requires real-world medical data to conduct research and test
hypotheses in real-world scenarios using real-world data.
Deidentified patient data is required for clinical trials. Consolidating
and de-identifying patient data takes a lot of time and work, and it
costs a lot of money. The availability of huge collections of real-life
de-identified raw data, analyzable datasets for secondary analysis,
and metaanalysis is a significant aspect in achieving improved
accuracy in clinical research and trial outcomes. According to polls,
the majority of customers are willing to provide their medical
records for analysis and study as long as their privacy is Protected.
Here’s where healthcare blockchains play significant roles. There
is a great degree of transparency because trust is embedded into
the blockchain database. Records are publicly writable by
everyone and are not owned (stored) by anyone, with encryption
providing data protection. A shared ledger can promote information
sharing and community-driven clinical studies by utilizing private
and public key encryption. Patients have direct control over their
medical data, including the ability to approve or deny access to
care providers and organizations. A platform like this would be
critical in assisting research organizations in gaining direct and

secure access to a large database of comprehensive and accurate
clinical data.
3. Blood Chain Tracking
The present challenge with blood donor monitoring, particularly in
the developing countries, is that there is no uniform, low-cost, and
transparent system in place. We can trace a receiver from a blood
donor where a specific blood has been donated, the donor's
compliance information, and if / where it has been tested using
blockchain technology. But our company doesn't stop there; it also
makes general medical data, such as shot records, available on
the blockchain.
This is in contrast to a healthcare blockchain based environment,
which consists of blockchain-hosted medical data that is mined and
evaluated using distributed AI. As a result, researchers can
forecast the effects of certain diseases with near-perfect accuracy,
and the government can verify compliance in medicine, such as
blood donation.
4. Plasma Supply Chain
In this part, we'll look at some of the ways blockchain can be used
in the plasma supply chain. We don't want to lay down a complete
specification; instead, we want to generate ideas for additional
research and experimentation. It's easy to see how blockchain
could be applied to the plasma supply chain in the same way it is
to the pharmaceutical supply chain. The application cases linked to

preventing the falsification of plasma products and plasma logistics
are self-evident.
To begin with, blockchain might be used in the same way that
MediLedger is used to combat
fake pharmaceuticals. A private blockchain hosted by plasma
supply chain nodes representing supply chains would be the major
components here. A unique identifier would be provided to each
plasma supply, which would be kept in the blockchain with the
certificate of origin. As the delivery moves through the supply chain,
each step is recorded in the blockchain, along with other pertinent
data. Supply chain parties can use their nodes to connect to the
blockchain and inquire about delivery origins and individual
donations while retaining a high level of privacy. The major role of
blockchain in this scenario would be to validate logistics
transactions and create an immutable ledger, preventing attempts
to tamper with origin information or inject phony plasma into the
supply chain.
5. Verification of Medical Staff Credentials
It is pivotal to verify the information related to the medical staff
credentials for authentication purposes. Their expertise, degree,
previous institutes, experience, previous workplaces, and other
related information must be verified and at the same time it should
be ensured that they are not compromised.
Blockchain technology can not only simplify the hiring process by
providing authentic information related to all these, but it also

provides high security to ensure such data is not compromised. For
instance, US based ProCredEx has launched a blockchain system
to verify the credentials of medical staff. This system is based on
the R3 Corda Blockchain Protocol. Be it virtual healthcare solutions
delivery or better transparency for sub-contracting organizations -
healthcare blockchains have become a crucial component for
modern day digital health.
The Bottom Line
As discussed above, healthcare blockchains have become
an integral part of today’s healthcare sector. Hospitals to
pharmaceutical and medical sectors - they are being used
to provide with compact and secure solutions for multiple
purposes. With more and more people related to the
healthcare profession getting aware of the healthcare
blockchains, their applications are expected to become
more prominent in the coming years.
