Healthcare industry use digital methods for maintaining electronic health records. From patient’s personal information to different diagnostic reports, and doctor’s prescriptions, healthcare organizations, currently use centralized servers for saving various types of data. The server’s owned by private companies or health information exchanges.

Ponemon Cost of Data
Breach Study
Estimated to be $380 per record

7. Health Information Exchange is
another TIME-CONSUMING and
complicated process

8. 2015 2016 2017
450 breach incidents occurred but
information was only available for 380
breach incidents
X27,314,647 affected
patient records

9. HOW CAN BLOCKCHAIN
IMPROVE THE HEALTH
RECORD MANAGEMENT?

10. Entire healthcare
blockchain solution
could be divided into
5 MAJOR STAGES
Capturing of healthcare data
Cleaning and Enrichment of data
Storing data on the blockchain
Consumption of data
Data mining with AI and ML

11. To integrate blockchain into healthcare, first, we need to
understand the scope of data and where and how it is being
generated

12. Three fundamental things to be done to clean and secure the
data before storing on to the blockchain

13. Replace the
patient’s identity
with the public
hash key
Make it
compliance ready
Add meta
information and
structure it for
computation

14. Replace the
patient’s identity
with the public
hash key
Using “Hash” instead of
an individual’s name
would make it
impossible for the
attacker to decode the
data
Make it
compliance ready
Patient’s information or
medical data should
adhere to healthcare
compliance
Add meta
information and
structure it for
computation
The medical data is
categorized in different
formats. Applying
computation to clean
the data is essential to
store it in a well-
structured way

15. Blockchain enables the digital health records to be distributed
across nodes within the network

16. Everyone who wants to access the
patient’s data would require a
PRIVATE KEY to uncover the medical
data

17. Healthcare providers can provide
better services with more
ACCURATE DATA

18. Stakeholders involved in the treatment of a patient can
consume the stored data using patient’s private key

19. When the data is saved on the blockchain, Smart contracts are
triggered
Healthcare provider receives the patient’s report with a hash that
does not reveal the identity
The smart contract events will also notify the patient or the
emergency contact to authorize to see the information

20. Healthcare information system on blockchain can also capture
the data for medical research

21. Healthcare providers can provide
better services with more
ACCURATE DATA

22. Data Mining is an analytical
method used for computing and
DISCOVERING RELATIONSHIPS in
large data sets
