Blockchain: How is it impacting healthcare?

Julie Carty

Big Data, artificial intelligence, predictive analytics all are terms that are becoming increasingly familiar to the healthcare industry.  Blockchain however, is still a bit of a mystery. Today were going to take a quick look at; what exactly is blockchain? what are its initial applications within healthcare? and who are the key players driving this innovation?

What is it?

Blockchain is a distributed data structure that can be time-stamped and signed using a private key to prevent tampering. Originally established within the  financial services, it is now the underlying tech for bitcoin and other cryptocurrencies.

What are its initial applications in healthcare?

Siloed data is one of healthcare’s biggest challenges. The technology behind blockchain has the potential to significantly improve this lack of interoperability. Moreover, the technology can provide an extra layer of security to data – something that will sit well in an era where there is an ever increasing threat of cyber hacks against hospital systems, and while the security of patient’s medical records are under threat.

Blockchain in Action

Blockchain decentralizes health data. The patient, provider, and payor are all provided with separate codes (hashes) to unlock the patient’s data. The patient defines their profile and the access rules required to unlock their medical records.

Key Players in the Space

What’s a Rich Text element?

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
