Research Strategy:

Our research began by checking statistical sites, research firms, and media sites for any reports on the U.S. TAM growth for AI and machine learning in healthcare in 2014. Thus, we explored research firms such as Research Gate, Docs Player, Technavio, Industry Daily Observer, Grand View Research, Business Wire, and Globe-News Wire for relevant information. We also checked statistical and consulting websites, including Statista, Deloitte, KPMG, and McKinsey. Also, we reviewed media websites like Reuters, Forbes, and The NYT.

On the website Pymnts, we discovered that North America is leading the global market of AI and machine learning in healthcare with the United States serving as one of the major contributors to the region’s AI-in-healthcare market. Additionally, while exploring Market Watch, we found that the U.S. market size for AI and machine learning in healthcare was valued at around $320 million in 2016, and the market was anticipated to grow at a compound annual growth rate (CAGR) of about 38% until 2024. We decided to utilize this data to calculate the 2014 TAM, assuming that the market had grown at the same CAGR between 2014 and 2016 (38%).

To calculate the 2014 market size, we used the following equation:
  • Market size for previous year = market size of next year - (market size of next year x CAGR)
  • 2015 market size = 320,000,000 - ($320,000,000 x 38%) = $198,400,000 or $198.4 million
  • 2014 market size = 198,400,000 - ($198,400,000 x 38%) = $123,008,000 or $123 million
Therefore, we estimate that the TAM for AI and machine learning in healthcare in the United States in 2014 was roughly $123 million.

AI/ML Use Cases

Artificial intelligence (AI) and machine learning (ML) technologies have seen rapid growth in various sectors of the global healthcare industry. AI and ML technologies are helping healthcare providers in several facets of the industry from cutting costs on health operations to improving the overall quality of patient care. AI technologies are currently making great headway in boosting efficiency, improving outcomes, influencing healthcare innovations, and impacting every aspect of healthcare. Some key healthcare AI/ML use cases include research and clinical decision support, medical imaging, clinical trial matching, and medical knowledge management.

Use Case #1: Clinical Decision Support

  • It is known that medical diagnosis is a highly collaborative and intricate process that is susceptible to inconsistencies and errors affecting everyone involved, from hospital staff to patients. To help reduce the number of diagnostic errors and improve the overall process of diagnosis, AI-powered tools, programs, and platforms are being used by clinicians and physicians. The primary aim of using AI in clinical decision support is to provide better care plans and deliver better treatments by reducing diagnostic errors.
  • According to the Director of Research Strategy and Operations at MG/BWH Center for Clinical Data Science, Dr. Katherine Andriole, AI can be a valuable asset in helping physicians make accurate decisions based on patterns identified from a large collection of digital data. AI systems can analyze vast amounts of data in seconds and organize them in a coherent manner to help physicians quickly connect the dots in the treatment of patients, especially in the ICU.
  • In AI-based clinical decision support systems, the platform (computer) behaves as a knowledge base that generates patient-specific recommendations and assessments which are then presented to researchers or clinicians for further consideration. The AI system can offer support and provide necessary recommendations in real-time at the location where the healthcare profession is making the clinical decision. This helps the clinician to provide the patient with the best treatment possible.
  • Cognitive computing systems that utilize machine learning, natural language processing, and other AI technologies, are innovative AI systems that synthesize data to provide a simple answer for a particular question. These systems are mainly used in the field of oncology where AI recommendations are always evaluated by a physician. One such cognitive computing system is IBM’s Watson Oncology.
  • Watson Oncology was designed and developed by IBM in collaboration with Memorial Sloan Kettering Cancer Center as a cognitive computing application. The product is trained with over 13 types of cancer.
  • During a pilot test, IBM Watson was provided with an algorithm that searched across note sections, clinical records, and various other data to learn the key predictors and markets for congestive heart failure. Watson was able to analyze 21 million patient records in a span of six weeks and developed a code that achieved a risk identification accuracy rate of over 85%.
  • Various companies operating in the healthcare industry use AI in clinical decision support such as IDx, Apple, and Aidoc.
    • IDx is a Coralville-based healthcare firm that has designed an AI diagnostic system enabling physicians to identify diabetic retinopathy by analyzing a batch of retina images. In a single minute, the AI tool identifies the eye condition and provides recommendations for the physician. The tool has been approved and used in the University of Iowa Hospitals and Clinics.
    • Apple has developed AI sensors that are connected to its flagship wearable to help identify atrial fibrillation in customers. This AI-based application is used by customers under the age of 55.
    • Aidoc, located in Israel, has designed an AI-powered brain solution that detects cases of internal bleeding. This clinical decision support system utilizes AI and deep learning to assist radiologists in cases of acute intracranial hemorrhage.

Use Case #2: Medical Imaging

  • Medical imaging is found to be one of the most complex sources of patient information. AI-powered tools that are integrated with medical imaging provide physicians with the required support to precisely diagnose specific conditions. According to Dr. Katherine Andriole, imaging analytics is a common field of AI application to help enhance physicians’ decision-making capabilities.
  • It is found that even the most experienced medical professionals have difficulties in manually analyzing high-resolution images in large numbers. AI-driven systems in medical imaging can compute a vast number of images and provide analysis from CAT scans, X-rays, MRIs, and various other testing modalities, thereby, aiding clinical professionals in improving their accuracy in identifying conditions and providing treatments.
  • Algorithms are written to accurately and quickly diagnose conditions by reviewing millions of images. For example, an algorithm for a medical imaging tool can be written to look through a vast number of chest films, with malignancies and without, in order to learn to spot malignancies. It is to be noted that these AI tools do not provide the end solution or make decisions but provide recommendations for the physician to make the final call.
  • Some specific uses of AI in medical imaging are to identify cardiovascular abnormalities, to detect fractures and other musculoskeletal injuries, and to aid in the diagnosis of neurological diseases.
    • Identifying cardiovascular abnormalities: AI medical imaging tools are used as an initial screening tool to detect abnormalities in imaging tests that are commonly ordered such as x-rays. In this case, algorithms are written to automatically develop reports, highlighting the different measurements that are considered abnormal, thereby, saving time for clinical professionals.
    • Detecting fractures and injuries: AI imaging tools use algorithms that review various images, particularly in trauma patients, to help identify and account for every single injury. This AI application helps reduce patient risk, false negative risks, and medical-legal risks for radiologists.
    • Aiding neurological disease diagnosis: In this case, AI tools use algorithms that streamline the entire diagnosis process by identifying images that show evidence of amyotrophic lateral sclerosis (ALS). These algorithms can be written to provide automatic reports to reduce the workflow burdens on healthcare providers.
  • According to a report published by Signify Research, the AI market in medical imaging is set to experience rapid growth and is expected to generate $2 billion in revenue by 2023. This particular market is driven by specialist software developers and start-ups that are using machine learning and AI technologies to further develop medical imaging. Some notable companies operating in the healthcare industry that use AI-powered medical imaging tools are Tencent (China), Alibaba (China), and IQRAA Hospital (India).

Use Case #3: Clinical Trial Matching

  • In the field of oncology, cancer clinical trial coordination is found to be extremely difficult and most often the numbers are not in favor of the patients or the medical staff. In the United States, less than 5% of those diagnosed with cancer participate in clinical trials and 20% of these trials are “stymied due to lack of patient recruitment”.
  • There is a considerable disconnect in the recruitment of patients in clinical trials due to the daunting process of data-matching. Identifying patients with the correct clinical attributes and who meet the right eligibility criteria is a lengthy and complex process. Manual recruitment process, imprecise criteria, and unstructured healthcare data are the main reasons for the “cumbersome clinical trial identification”.
  • To solve this problem, AI-powered screening processes are used to help increase the speed of identifying accurate clinical trial matches. In this case, AI-powered matching solutions are able to compute vast amounts of structured and unstructured data pertaining to patient EHR information, trial data, medical literature, and eligibility criteria. These AI tools are developed using natural language processing which allows the AI system to examine all the gathered information in a short period of time.
  • Clinical trial matching AI systems can take structured or unstructured, lengthy, and inexact criteria information and learn to interpret the requirements of the clinical trial, specific to each patient. Therefore, an AI-based system will be able to quickly understand the exclusion or inclusion criteria of the clinical trials and the medical record’s clinical data. In a particular study conducted by IBM Watson Health, AI-powered identification reduced the screening of patients for the eligibility of a clinical trial by 78%.
  • With the use of AI matching/identification systems, clinicians will be able to identify trials that can be considered as treatment options and can continuously analyze available patients for clinical trial eligibility. In the United States, the adoption of AI-based tools in clinical trial recruitment is found in research and academic medical centers.
  • According to Forbes, The Opportunity Project (TOP) team created an AI-based system that matches patients to clinical trials, this year (2019). This initiative is a collaborative effort of a number of nonprofits and technology providers and was headed by the Presidential Innovation Fellows and the United States Health and Human Services Office of the Chief Technology Officer.
    • The first stage of this process includes a chatbot that answers questions asked by patients about their cancer treatment. The chatbot provides necessary background information on the subject through a voice interface of conversational text.
    • In the second stage of this process, the patient agrees, through the chatbot, to email his/her doctor for further medical information that is needed for a clinical trial. A clinician enters the provided information into the TOP app by following a guided process. The app is designed to find clinical trials that the patient is eligible for.
    • In the final stage of this process, the patient obtains the information in the form of an interactive map that shows where the clinical trial is located and allows the patient to read more about the clinical trial by clicking on the map.
  • London-based company, Antidote, and California-based firm, Deep 6 AI, are two companies that have developed AI-based patient recruitment systems.

Use Case #4: Medical Knowledge Management

  • Numerous companies, healthcare firms, hospitals, clinics, and medical universities are leveraging AI technologies to develop better healthcare data management and medical knowledge management systems. A popular form of medical knowledge management powered by AI is virtual reality and augmented reality platforms that are designed to educate doctors, nurses, surgeons, and medical students in conducting surgical procedures.
  • In Japan, there are 12 hospitals that use VR modules from technology provider, HoloEyes, to view three-dimensional models of organs like kidneys and livers. The VR modules allow medical professionals to accurately plan the finer details of critical surgical procedures. Another Japanese company, Intuitive Surgical, has developed a VR simulation training module for medical professionals to help train on certain procedures.
  • Johnson & Johnson Institute, an Ohio-based establishment, has developed a VR platform that helps train surgeons, doctors, nurses, and students in a large selection of surgical procedures. This platform utilizes deep learning technology that allows medical professionals to experience and learn real-world scenarios without actually being present in a physical training room.
