Unintended consequences of new technologies in healthcare – thoughts on #blockchains pt 2 by Dr. Senthil N @nacsen


In part one of this blog I discussed blockchains and how they could be used in health care in an ideal world. 

In the real world however, block chain use poses many challenges. The challenges range from security to accessibility perspectives, some of which are unique to health care. In a healthcare blockchain, each unique identifier is a human being, not a piece of cryptocurrency. So, anyone with access to a blockchain can see how many transactions a patient has had and their timestamps, then extrapolate how healthy or sick a person has been.

Unintended consequences of new technologies in healthcare – thoughts on #blockchains, Part 1 by Dr. Senthil @nacsen

As cameras with more than 20 megapixel resolution become commonplace, many daylight photographs would meet this criteria. It is not farfetched to imagine that one could copy iris patterns from portrait photographs just as easily. For the majority of the world population with darker eye colors, their iris patterns would not be clearly visible in the visible light wavelength, which is why iris scanners use near-infrared wavelengths.

India has just seven registered allopathy doctors per 1,000 people. Indian healthcare was ranked 112th in the world in a survey by the WHO. It is therefore unsurprising that most discussions in the healthcare sector today are focused around ways and means to build more infrastructure and increase access to care.
