Update on Artificial Intelligence and Healthcare

The sheer volume of available medical knowledge has long since outstripped even the most capable clinician's ability to review and properly analyze the all the data now being generated and collected about a patient's health. Today it requires the assistance of sophisticated computer systems to not only help them with the analysis of the data, but to also stay on top of breakthroughs in genomics, predictive analytics, clinical decision support, population health management, and the continuous changes in best practices.

Even the best, most attentive health care providers simply can’t stay on top of all the data and the growing body of ever-changing medical knowledge. Doctors just can't be there for a patient around the clock, to catch every bad habit or reinforce every positive behavior. However, Artificial intelligence (AI) has evolved to the point that it can now begin to significantly augment the healthcare provided by physicians, pharmacists, nurses, and health coaches – not to mention self care.

Today, over 90 Artificial Intelligence (AI) startup comanies are already active in developing new solutions in the areas of Imaging & Diagnostics, Drug Discovery, Remote Patient Monitoring, Hospital Management, Customer Service, Healthcare Analytics & Research, Patient Alerts & Reminders, Telemedicine, Public Health, and more.

AI Market & Financial Investment
According to a recent 2016 report by Frost & Sullivan, use of AI is growing in healthcare, with the market poised to reach $6 billion by 2021, up from $600 million in 2014. Cognitive solutions such as IBM’s Watson system are capable of sifting through huge volumes of data and providing guidance and decision support to healthcare providers, thereby improving work flow and patient care.

IBM is serious about bringing Watson into the healthcare industry. To build Watson’s medical credibility, IBM has spent $4 billion dollars purchasing companies that had huge stores of medical data, from billing records to MRI images.

Artificial Intelligence (AI) coupled with the Internet of Things (IoT) could be the answer to solve major healthcare challenges that the world is facing today. IoT can helping care to move from hospital to home in low acuity and post-operative scenarios, with wearable sensors being monitored and analyzed continuously in real time by AI systems. The number of connected IoT healthcare devices is estimated to be $2.5 trillion by 2025. For more detail, read IoT and AI: Potent combo redefining healthcare.

Key Issues

Artificial Intelligence (AI) technology already exists, and is being deployed in many other arenas, such as finance and business intelligence. But in health care, there’s a human and psychological barrier: can we trust AI with our health?

Some of the key issues that need to be addressed over the coming decade before Artificial Intelligence (AI) systems are widely deployed include:
  • Ethics - This emerging issue is concerned with the moral behavior being programmed by humans into robots and other 'smart' AI systems, e.g. Roboethics.
  • Privacy & SecurityWhen AI systems are turned loose to monitor health information systems gathering data on all facets of your personal health, concerns about who has access to the data and who it is being shared with are just a few of the issues that must be adequately addressed upfront.
  • Jobs - The Bank of England has predicted that intelligent machines might take over 80 million American and 15 million British jobs, respectively over the next 10 to 20 years. The healthcare industry will not be immune to this change.
  • Legal Issues - One of the most important points of interest that needs to be hammered out first is the legality of these machines. When a doctor's gross negligence leads to a misdiagnoses and patient harm, the fault is placed squarely on the shoulders of the offending physician. What happens if an AI system were to misdiagnose a patient? Who's to blame?
  • Open Source - Many new 'open source' tools are arriving that can now run on affordable hardware and allow individuals and small organizations to perform prodigious data crunching and predictive tasks.

Conclusions & Next Steps

When and how artificial intelligence (AI) systems will stand in for doctors, nurses, therapists, or specialists is yet to be determined. The use of AI systems is already fairly prolific in some other industries. But the consensus is that these systems aren’t yet sophisticated enough for use in healthcare. However, expect all major electronic health record (EHR) systems of the future to include an AI platform within their architectural structure.

At this stage, AI is perceived as one of a group of emerging technologies that will increasingly be used to augment human capabilities. However, within 10 years AI coupled with IoT, Blockchain technology, and 'Big Data' Analytics may actually be used to carry out many of the functions currently being performed by clinicians.

As we continue to move forward with further development and deployment of AI systems, the following are some of the next steps that need to be taken:

  • Ethical rules and standards to be incorporated in AI systems used in the healthcare need to be extensively addressed.
  • The health IT industry needs to take careful, incremental steps when developing and implementing AI systems in healthcare over the next decade to avoid causing any harm.
  • Medical professionals need to become much more knowledgable about AI technology and systems and work closely with developers before we move forward much further.
  • Patients need to get accustomed to interacting with AI systems, discovering the potential benefits to themselves – to trust these new systems.
  • Companies developing AI healthcare solutions need to carefully communicate with the general public about the potential advantages and risks associated with the use of AI in medicine.
  • Healthcare oversight institutions need to carefully measure the success, shortcomings, and effectiveness of AI systems before they are widely deployed over the coming decades.
