activities and more efficient processing. This could help
minimize medical frauds which can cause more than $30
million losses in a year.
Contribution of Wearables
Wearables and internet of things devices can also be
integrated into the health IT ecosystem through blockchain.
Health wearables are currently storing critical information
for clinical research, outcomes of treatments, and disease
prevention and management. If validated, this data can be
secured, shared and verified on a blockchain and thus the
function of health wearable will take on a whole new role.
Electronic Health Records
Blockchain can help enhance three major features of the
EHR systems:
Immutability via File Integrity: Each event on the
blockchain has a unique combination corresponding to the
contents of a record. This means that the users can verify if
the status of the content of the records has been changed or
not.
Cybersecurity via Data Access Management: Each
combination may contain particular user permissions for
doctors, patients, nurses or any authorized users or devices.
Therefore, only authorized personnel may access record
information.

Interoperability via Collaborative Vision Control: Each
party has a record linked to the original record that is
registered to the blockchain. Thus, everyone who has the
appropriate role and responsibility can add information to
the record while avoiding issues such as inconsistent or
duplicate records.
Data Security
With the growth of connected devices and the Internet of
Medical Things (IoMT), existing health IT architecture is
struggling to keep systems secure. Blockchain technology
has the potential to be the infrastructure that is needed to
keep health data private and secure while reaping the
benefits of connected medical devices.
There are some incredibly exciting ways in which
blockchain can enhance healthcare operations, however,
more research, trials and experiments must be carried out to
ensure a secure and established system is implanted before
using blockchain technology on a large scale in healthcare.
Today, the healthcare industry is drowning in data- clinical
trials, patient medical records, complex billing, medical
research and more. Adoption and implementation of
blockchain will be an evolution over time as blockchain
applications are vetted and adopted as well as the industry
coming together to determine collaboration and governance
issues.
