Artificial Intelligence becomes an essential part of future healthcare
In many developed countries, healthcare has become an unsustainable business in recent years, partly due to the aging population and prevalence of chronic diseases. In the US, healthcare spending grew 4.6 percent in 2019 alone, amounting to US$3.8 trillion, or 18 percent of the nation’s Gross Domestic Product (GDP). However, this increase in spending did not translate into better patient care, nor has it reduced resource scarcity and imbalance in the healthcare industry. How can we transform the healthcare sector to make it more efficient and sustainable? Artificial intelligence (AI) will play a critical role in the future of healthcare.

From fee-for-service to fee-for-value
In the current healthcare system, doctors and other healthcare providers are paid for the number of patients seen or procedures performed. This fee-for-service model means that healthcare providers are rewarded for volume rather than for value.
What is the biggest barrier to practicing medicine today?
“‘Production pressure’ – the requirement to see more patients in less time because of the misconception that the value of a physician is determined by the number of patients he/she sees”– Lucian Leape, physician and professor at Harvard School of Public Health, leader of patient safety movement.1
Value-based healthcare rewards healthcare providers based on the quality of care they provided. The implementation of AI can greatly improve the value of healthcare providers by making sense of medical data, automating routine procedures, and improving efficiency and effectiveness.
AI will reshape radiology
Machine learning is great at recognizing patterns, which has translated into fast progress in analyzing medical images.
While AI played no role at all in radiology as recently as 2015, 30 percent of radiologists had adopted the technology by 2020, according to a study by the American College of Radiology.2
One of the diseases where machine learning has proven its value in early diagnosis and prognosis is dementia, the leading cause of disability and dependency among the elderly. Diagnosing dementia in an early phase is a challenge due to the lack of symptoms and visible changes in brain images at the preclinical stage. By studying patterns in thousands of brain scans from dementia patients, scientists in the UK have developed an algorithm that can detect early signs of dementia in brain scans that are not visible even to radiologists. The algorithm has reduced the diagnosis procedure from several scans and tests across several weeks to just one single scan.
Data experts believe that AI, rather than replacing radiologists Altogether, will automate redundancies, prevent mistakes, and optimize how radiologists practice, which will ultimately lead to better patient outcomes.3
AI and big data are advancing precision medicine
All humans are different from one another due to genetic, environmental, and lifestyle factors. But in conventional medicine, patients with the same disease are typically given the same standard treatment. This is often the reason for unreliable outcomes. In precision medicine, medical decisions are tailored to a subgroup of patients. Multidimensional datasets are used to train algorithms to identify subgroup patients with similar biological and other characteristics. Precision medicine offers clinicians the opportunity to prepare tailor-made preventative or therapeutic interventions. It has already led to promising results in AI-powered prognosis for cancer and cardiovascular disease.4
In 2018, Chiba University set up the first AI center in a medical school in Japan. The center uses AI to analyze genomic and clinic data such as gene expression, metabolism, gut microbiome, environmental exposures, and lifestyle factors. By doing so, researchers are able to predict the efficacy of treatments and future outcomes. In one of their studies, researchers used machine learning to identify a group of early-stage ovarian cancer patients who would respond poorly to a particular treatment beforehand. This finding gave the clinicians the opportunity to design a new treatment approach for the subgroup of patients.
“Predictive algorithms can help identify disease groups that haven’t been recognized by clinicians, as well as guide the selection of personalized treatment options for these patients.” – Eiryo Kawakami, professor of artificial intelligence medicine at Chiba University.5
Translate AI from labs to real-life patient care
To laypeople, the notion of an AI healthcare solution may sound like a complex one. But Professor Sebastien Ourselin, Head of the School of Biomedical Engineering & Imaging Sciences at King’s College London, says the new approach will make his work easier. Ourselin and a team of data scientists and clinicians at AI Centre for Value-Based Healthcare are working together with The National Health Service (NHS) and other partners to deploy AI solutions into real hospitals in the UK.
“AI is just a way to make sense of all of those data by training models which will hopefully be able to save us time in making the diagnosis, prognosis and be able as well to increase the effectiveness of the treatment.” – Professor Sebastien Ourselin, Head of School of Biomedical Engineering & Imaging Sciences at King’s College London6
The transformation of AI solutions from labs to real patient care is not an easy task. Medical data in the real world is often unstructured, comprehensive, and filled with various terms, abbreviations, and misspellings. The strategy of the AI Centre for Value Based Healthcare is to first convert static snapshots of clinical data into real-time, actionable analytics, then build an infrastructure to link data together and train the algorithm. Eventually, with the help of AI, actionable models are formulated that can be deployed in real hospitals. The NHS plans to deploy the first prototype in ten hospitals later this year. The full deployment of AI solutions will be carried out in the next two years.
