Artificial intelligence in healthcare has the potential to transform many aspects of patient care and administrative processes in healthcare. I think the role of artificial intelligence will be an asset to all healthcare professionals. The following article contains examples of artificial intelligence in healthcare and companies doing a great job at it.

Introduction – Artificial Intelligence in Healthcare.

Artificial intelligence (AI), Machine learning, NLP, Robotics, and Automation are increasingly prevalent in all aspects and are being applied to healthcare as well. These technologies have the potential to transform all aspects of health care from patient care to the development and production of new experimental drugs that can have a faster roll-out date than traditional methods.

There are numerous research studies suggesting that AI can outperform humans at key healthcare tasks, such as diagnosing ailments. Here is a great example, AI ‘outperforms’ doctors diagnosing breast cancer¹.

Artificial intelligence is a collection of technologies that come together form artificial intelligence. AI’s diverse range of technologies impacts a wide spectrum of healthcare.

Tech firms and startups are also working assiduously on the same issues. Google, for example, is collaborating with health delivery networks to build prediction models from big data to warn clinicians of high-risk conditions, such as sepsis and heart failure. Google, Enlitic, and a variety of other startups are developing AI-derived image interpretation algorithms. Jvion offers a ‘clinical success machine’ that identifies the patients most at risk as well as those most likely to respond to treatment protocols. Each of these could provide decision support to clinicians seeking to find the best diagnosis and treatment for patients.

You will find below some technologies that improve a specific area in healthcare with examples sourced from the internet with citations.

Machine learning

Machine learning is an application of artificial intelligence (AI)that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it to learn for themselves².

There are majorly three types of Machine learning —

  • Supervised Learning
  • Unsupervised Learning
  • Reinforcement Learning

In healthcare, the most common application of machine learning is predictive medicine  —  predicting what treatment alternatives are likely to work best on a patient based on various patient traits, history, the treatment situation, and protocols. The supervised learning model for predictive medicine applications requires a training dataset, like all supervised learning models. the difference here is that there may be a lot of variables.

Using neural networks it is now possible to also predict whether a patient will acquire a particular ailment or not based on a set of variables and conditions that can be fed into algorithms in the form of data.

One common application of deep learning and neural networks is the ability to detect ailments/issues in the radiology images. I think deep learning should be increasingly applied wherever clinically possible. This will allow doctors and radiologists to just supervise results and focus on other important aspects of their job. This combination promises better accuracy of finding ailments with limited human intervention or supervision.

Here are some organizations that are doing groundbreaking work in this area.

Natural language processing

In healthcare, most applications of NLP involve the creation, understanding, parsing, and classification of clinical documentation and published research. NLP can also be used to analyze clinical notes, prescriptions, help prepare reports, and possibly conversational AI. Few good examples of how NLP is currently being used.

  • Parsing data realtime from coronavirus research that is being published globally. You can find more information about this in my article here.
  • Project Meena by Google. More information can be found here.

Decision Tree

Decision trees require doctors and engineers to come up with an if-then-else decision flow chart that can help train machines to make decisions by building complex algorithms based on the finalized decision tree. This is critical and processes heavy software design, this enables the machines to take accurate decisions with human intervention. This will help save a ton of time for doctors and patients alike. This will enhance the capabilities of doctors to predict, analyze, and come up with a treatment plan for patient care.

This can also be used extensively in vaccine and treatment research provided the known variable is the ailment we are making the vaccine for and its pre-set conditions and protocols. This is an effective mechanism for pre-morbidity patients as well.


Robots are becoming more intelligent, as other AI capabilities are being embedded in their OS. Other areas of improvements in AI have exponentially improved the capabilities of the robots and their ability to perform complex operations.

One such area of operation is robotic surgery. This enables surgeons to perform complex procedures with much greater precision and create precise, minimized, invasive incisions, and stitches. This is a game-changer in performing surgery, as long as human supervision exists.

Robotic process automation

Robotic process automation performs structured digital tasks for administrative purposes, ie those involving information systems, as if they were a human user following a script or rules. It relies on a combination of workflow, business rules, and ‘presentation layer’ integration with information systems to act like a semi-intelligent user of the systems. In healthcare, they are used for repetitive tasks like prior authorization, updating patient records, or billing. When combined with other technologies like image recognition, they can be used to extract data from, for example, faxed images in order to input it into transactional systems.

Mass personalization

Artificial Intelligence can help in mass personalization of patient care, treatments, procedures, vaccine research, and production. This along with human interaction can reduce costs and improve coverage across the board for healthcare.

AI can help with various aspects of patient care, like, charting the history of the patient, admission process, diagnosis, tests, treatment plans, and procedures. AI can help in every aspect of patient care including helping hospital administrators with managing massive amounts of patient data and patient care options.

AI can also help with patient adherence to treatment and management of the ailments or prophylactic care. This can help in reducing health care costs on the individual patient. if this is implemented on a large scale this can cut down or reduce healthcare costs. These savings can be re-invested in more advanced equipment, technology, better education for doctors, and healthcare professionals in a technologically shifting landscape.

Here are some examples of organizations working in this area.

Hospital administration

There are also a great many administrative applications in healthcare. The use of AI is somewhat less potentially revolutionary in this domain as compared to patient care, but it can provide substantial efficiencies.

Using the patient profile AI can be used to predict the type of care, specialists, nursing staff, equipment, bed occupancy, tests, and medication requirements per patient, this will help hospital administration in better procurement procedures and reduce wastage. The advanced version could also automate the procurement and help with predictive ordering to avoid shortages at hospitals. This can also help in reducing the space required for storing all this equipment as well, as predictive ordering and robotic automation process can improve supply chain capabilities. This will help hospital administrators make efficient calls in terms of staffing hospitals with the right level of resources being maintained at all times.

AI can be used for a variety of applications in healthcare, including claims processing, clinical documentation, revenue cycle management, and medical records management etc. AI can also be used to improve payment processing systems, third party integration with insurance companies, labs.. etc. Reduce time for claims and improve the user experience of patients/families who are already distressed when visiting the hospital.

Ethical implications of artificial intelligence in healthcare.

Finally, there are also a variety of ethical implications around the use of AI in healthcare. Healthcare decisions have been made almost exclusively by humans in the past, and the use of smart machines to make or assist with them raises issues of accountability, transparency, permission, and privacy.

Perhaps the most difficult issue to address given today’s technologies is transparency. Many AI algorithms — particularly deep learning algorithms used for image analysis — are virtually impossible to interpret or explain. If a patient is informed that an image has led to a diagnosis of cancer, he or she will likely want to know why. Deep learning algorithms, and even physicians who are generally familiar with their operation, may be unable to provide an explanation.

Mistakes will undoubtedly be made by AI systems in patient diagnosis and treatment and it may be difficult to establish accountability for them. There are also likely to be incidents in which patients receive medical information from AI systems that they would prefer to receive from an empathetic clinician. Machine learning systems in healthcare may also be subject to algorithmic bias, perhaps predicting the greater likelihood of disease on the basis of gender or race when those are not actually causal factors.

We are likely to encounter many ethical, medical, occupational, and technological changes with AI in healthcare. It is important that healthcare institutions, as well as governmental and regulatory bodies, establish structures to monitor key issues, react in a responsible manner, and establish governance mechanisms to limit negative implications. This is one of the more powerful and consequential technologies to impact human societies, so it will require continuous attention and thoughtful policy for many years.

The future of artificial intelligence in healthcare

We believe that AI has an important role to play in the healthcare offerings of the future. In the form of machine learning, it is the primary capability behind the development of precision medicine, widely agreed to be a sorely needed advance in care. Although early efforts at providing diagnosis and treatment recommendations have proven challenging, we expect that AI will ultimately master that domain as well. Given the rapid advances in AI for imaging analysis, it seems likely that most radiology and pathology images will be examined at some point by a machine. Speech and text recognition are already employed for tasks like patient communication and capture of clinical notes, and their usage will increase.

The greatest challenge to AI in these healthcare domains is not whether the technologies will be capable enough to be useful, but rather to ensure their adoption in daily clinical practice. For widespread adoption to take place, AI systems must be approved by regulators, integrated with EHR systems, standardized to a sufficient degree that similar products work in a similar fashion, taught to clinicians, paid for by public or private payer organizations, and updated over time in the field. These challenges will ultimately be overcome, but they will take much longer to do so than it will take for the technologies themselves to mature. As a result, we expect to see limited use of AI in clinical practice within 5 years and more extensive use within 10.

It also seems increasingly clear that AI systems will not replace human clinicians on a large scale, but rather will augment their efforts to care for patients. Over time, human clinicians may move toward tasks and job designs that draw on uniquely human skills like empathy, persuasion, and big-picture integration. Perhaps the only healthcare providers who will lose their jobs over time maybe those who refuse to work alongside artificial intelligence.
