Defining Digital Health

  • Conceptually,
    • Intersection between technology and healthcare
    • Digital transformation of healthcare
    • includes: software (apps), hardware and services
  • Digital Health Characteristics
    • Digitized - Digitization of all care touchpoints and backend process in healthcare
    • Demonetized - Decreasing cost by automation
    • Dematerialized - Materials are getting cheaper and faster including digital
    • Decentralized - Digital first allows to be global first
    • Democratized - Stakeholder economy with voting by wallet
    • Deregulated - Regulation is slow to catch with digital innovation
    • Deceptive - Suddenly becomes the norm (e.g digital camera)
    • Disruptive - Completely replaces older model (e.g. LED lights)
    • Exponential Growth - Algorithmic growth affects billions simultaneously

Defining Digital Health Technologies

💡
Definition of digital health technologies (DHT)
A system that uses computing platforms, connectivity, software, and sensors for healthcare and related uses. These technologies span a wide range of uses, from applications to support general wellness to medical device applications such as apps that provide a reminder to stay out of the sun to limit UV exposure. They include technologies intended for use as a medical product such as digital therapeutic that provides cognitive behavior therapy, a medical product that uses consumer technology in fitting a hearing aid, or as an adjunct to other medical products (i.e., devices, drugs, and biologics) such as an app to boost adherence to therapy. They may also be used to develop or study medical products.

Understanding digital Shift

  • Cultural Shift in the making
    • eCommerce
    • Remote work
    • Remote learning
    • Online Entertainment
    • Decentralized Finance (DeFi)
  • Impact of Pandemic accelerated the digital shift
  • It is estimated that the pandemic moved digitization at least 7 years forward

Digital Health Funding Landscape

  • $57.2 billion in funding in 2021
  • 79% jump from the $32 billion raised globally in 2020

Importance of Artificial Intelligence in digital Health

  • With the increased amount of data being produced
  • AI is not only an important but necessary part of digital transformation
  • Continuum of applied knowledge
    • Information > Data > Knowledge > Wisdom

Artificial Intelligence as a Service (AIaaS)

  • AI in healthcare will develop as a service model
  • Exactly as Sofware-as-a-service (SaaS) model
    • Cloudbase
    • API Based
    • Solve individual pain points
    • Produce value in niche areas
