What is #BlockChain? Implications for Healthcare by @msharmas

In my previous article I discussed about the benefits and barriers to the use of an Integrated Health Information Platform. In healthcare the need for presenting the Information to the Right Person at the Right Time has been proven to improve outcomes in patient treatment.

Will HIE 2.0 benefit from the use of Blockchain in presenting the information to the Right Person at the Right Time? 


What is Blockchain?
Various definitions of Blockchain have been put across based on the context of the use. Some of these definitions are: 

A digital ledger in which transactions made in bitcoin or another cryptocurrency are recorded chronologically and publicly.

“The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value.” Don & Alex Tapscott, authors Blockchain Revolution (2016)

The Blockchain is a decentralized ledger of all transactions across a peer-to-peer network. Using this technology, participants can confirm transactions without the need for a central certifying authority. Potential applications include, fund transfers, settling trades, voting etc.

Blockchain is a distributed system for recording and storing transaction records. More specifically, blockchain is a shared, immutable record of peer-to-peer transactions built from linked transaction blocks and stored in a digital ledger. [1]

A Blockchain is a data structure that can be timed-stamped and signed using a private key to prevent tampering. There are generally three types of Blockchain: public, private and consortium. [6]

Why Do We Want #Interoperability? by @Matt_R_Fisher

Interoperability, to a large degree, comes down to having a fully unified healthcare system where data is always available


A lot of time and attention has been put into the notion of interoperability by almost every stakeholder in the healthcare system. Those interested in the issue include patients, providers, vendors and the government. Why has interoperability received so much focus, though? It may be possible to answer that question by stating that interoperability contains a large element of the common good.

#Interoperability the Missing Link for #DigitalHealth Apps by @msharmas


In India we have 204.1 million smartphone users in 2016 [ http://www.statista.com/statistics/467163/forecast-of-smartphone-users-in-india/ ], it's only natural to find startups using the mobile as the way to acquire customers by providing mobile Health based products and services.

While it is a great way to provide accessibility and affordability of healthcare services via mobile health solutions, it is also important to understand the need to ensure interoperability of the healthcare data being captured in these apps.

SNOMED CT CSETS - Its Place and Use by @sbbhattacharyya


The Concepts related to CSets are as proposed by Dr. SB Bhattacharyya and presented in the HCITExpert Blog with permission from Dr. SBB - [email protected]

What is a Constrained Set?

  • The word constrain means “to control or limit something” (Cambridge Online  Dictionary)

  • SNOMED CT makes extensive use of refsets (reference sets), for a wide-range  of purposes, each of which have specific purposes

  • Refsets need to conform to certain specific rules and guidelines regarding their
preparation, distribution and maintenance
  • Takes a long time to design one and the designing entity needs to have a
 namespace assigned to it
  • This makes the rapid and effective use of SNOMED CT in individual systems  cumbersome at best and impractical at worst
