Abstract - The existing healthcare management system is
heavily reliant on paper-based records and centralized
databases. This makes it difficult to securely share patient
data between healthcare providers, resulting in delays in
treatment and potential errors in diagnosis. Furthermore, the
current system is prone to cyber attacks and data breaches,
putting patient privacy at risk. The lack of transparency also
leads to distrust between patients and healthcare providers.
A QR code or quick response code is a two-dimensional
barcode that can be scanned by a smartphone or a qr code
reader on the other hand blockchain technology provides an
easy and efficient way to store and retrieve information a
decentralized and transparent digital record and verification
of transactions on multiple computers the integration of qr
codes and blockchain technology in healthcare management
offers several advantages firstly it improves the security and
privacy of patient information by storing patient information
in the blockchain which is resistant to untrusted qr codes and
then patient information which ensures the integrity and
authenticity of the information used to link to related
notebook entries.
Secondly the use of qr code and blockchain technology
increases the efficiency of the health care process for example
when patients visit the clinic their code can be scanned to
access their medical history allergies and other relevant
information which eliminates the need for manuals
documentation and reduce errors or possible errors of
interpretation
Healthcare management is an important industry that
requires the integration of qr codes and safe andefficientdata
management as well as technologies known for privacy and
accessibility which can greatly improve qr code technology
which is the key to the unique identification of blockchain
technology for each be patient database provides an
immutable and distributed transparent ledger that ensures
the integrity of patient data2 this paper presents an
application that uses two methods to safely manage patient
data1 facilitates access to medical records and prescriptions1
that increases data availability and efficiency and improves
patient privacy health management that emphasizestheneed
to fulfill obligations.

1.INTRODUCTION
Healthcare management is being reshaped by blockchain
technology as it offers a secure and transparent framework
for data management and patient care. Blockchain
technology provides a secure storage solution for patient
medical records, safeguarding data privacy and facilitating
the effortless exchange of health informationamongvarious
healthcare providers. It enhances clinical trial integrity,
tracks drug supply chains, streamlines health insurance
processes, and supports telemedicine while ensuring data
authenticity. Furthermore, blockchain technology provides
patients withgreaterautonomyinmanagingtheirhealthcare
data and consent. It holds the promise of transforming
healthcare management through increased trust, improved
data security, and a reduction in administrative inefficiency.
This will eventually improve patient outcomesandmakethe
entire healthcare ecosystem more effective. Discover the
fundamentals of blockchain technology and how it may be
applied to healthcareadministration.Blockchainprovidesan
immutable, trustless, and decentralized way to store and
access data.
QR code-based blocking solutions can allow participants in
the care process to continue using the patient information
system during record exchange blockchain creates a single
immutable source of truth public record this single source
acts as a master record for all transactions containing
information about every transactionthattakesplacethink of
each transaction as a change toa patient recordthatrequires
real-time data sharing between multiple parties lack of
communication can lead to many directional problems
automating the approval process can solve such problems
blockchain is a great way to automate referrals because it
allows secure real-time data transfer between parties
reducing the possibility of errors conflicts and missed
connections each key actor in the development process
customers employees payers and maintenance team
members has real-time information on locked scenarios

blockchain in healthcare helps share data easily and quickly
qr codes can also be extended to make digital payments fast
and secure in an industry where time is truly precious time-
saving mechanisms like easy qr code generation and quick
sharing can be an asset in addition the supply team can
reduce network leakage because they have a better
understanding of real-time routing
While blockchain solves the problem of denying delayed
payment claims and sharing patient data there are still
challenges to unlock healthcare but it has the potential to
speed up the payment process between insurance
companies and providers allowing insurance companies to
automate more medical payments provide accurate and
precise information to patients and insurers in a secure
environment with secure communication between several
parties on a distributed basis recordblocksarerecordedand
visible to all parties eliminating the need for fax calls or
manual searches in the healthcare industry andinsurerscan
keep updated payment keys in the registration file and
blockchain distributed ledger technology will reduce the
need to store and record data on paper which can save
patients medical data simplify data management and help
the healthcare industry comply with government rules
distributed paper and only authorized users can access
doctors and insurance companies eliminating the need for
paper-based contact manuals thus increasing information
security for example when a doctor or patient scans a qr
code it immediately reveals medical and health information.
1.1 2. Methodology
Blockchain technology holds significant promise for
transforming the healthcare industry, particularly in the
realm of healthcare management. Blockchain, as a
decentralized and secure digital ledger, offers several
advantages in healthcare, including data security,
interoperability, transparency, and efficiency. Through a
thorough bibliometric studyusing bibliometric methodsand

security of transactions. [14]
2. Existing system:
Examining the current healthcare management system and
identifying its limitations and challenges. The existing
healthcare management system is heavily reliant on paper-
based records and centralized databases. This makes it
difficult to securely share patient data between healthcare
providers, resulting in delays in treatment and potential
errors in diagnosis [16]. Furthermore, the current system is
prone to cyber attacks and data breaches, putting patient
privacy at risk. Theutilizationofconsensus-basedblockchain
technology is advantageous in this scenario, as it guarantees
the data's integrity and transaction security. It could totally
change healthcare by making it easier and more transparent
how healthcare data is stored, shared,andmanaged.Without
transparency, people don't trust healthcare providers and
patients. Here's an overview of how the existing system of
healthcare management could leverage blockchain:
Management of Patient Records: Each patient would have
their unique blockchain identifier, and their medical history,
test results, prescriptions, and treatment plans could be
securely stored in a blockchain.

Interoperability: Healthcare blockchains can facilitate data
interoperability by providing a standardized format for
health data. This would make it easier for different health
care providers to get their hands on patientrecordsandkeep
them up-to-date while still keeping the data secure.
