This year WHO issued its first on Artificial Intelligence (AI) in health. The report is the result of 2 years of consultations held by a panel of experts. In 2020, Microsoft announced a five-year to combat healthcare challenges. But does it mean that AI is globally recognized as a viable disruptive force for healthcare? It does and it doesn’t. But more on that later. report $40 million program It is projected that by 2025, the AI healthcare market will increase to over U.S. dollars. That is a positive dynamic, considering the market of 1,4 billion in 2017. But how exactly can medical services benefit from intelligent systems? And what are the main limitations of AI in healthcare? 28 billion Let’s find out. No Longer A Science-Fiction From a historical perspective, AI has been around for quite a while. It was first described in 1950. Yet, it wasn’t until the early 2000s when limitations were overcome by the advent of deep learning and AI was widely accepted. By 2017, AI in medicine had transformed into the main industrial application of AI in terms of aggregate . equity funding And finally, the global artificial intelligence in healthcare market size was estimated at in 2020. But what caused the sudden spike in AI investments? $6.7 billion Here’s what has fast-forwarded the growth of the AI market in medicine: The pandemic-induced crisis distilled the need for digital and more accessible health services [1]; The influx of patient health-related ; digital data Growing healthcare ; spending Rising for personalized medicine; demand The increase in the prevalence of in an aging population. chronic diseases Hence, we can assume that intelligent systems were recognized as a new boundary for medical services. The current state of the AI market in healthcare demonstrates encouraging numbers: Over of practitioners feel that ML-powered processes could help the healthcare business resurface hidden or unattainable value. 93 percent For the healthcare industry, AI may , improve service delivery, and produce operational gains. improve patient outcomes AI technology has been in the ongoing COVID-19 pandemic and assisted in diagnosing virus strains. helpful Not a pipe dream anymore, I guess. Top Impacts of Artificial Intelligence In Healthcare From preventative care through enhanced medical decision-making to better patient outcomes, AI is becoming a part of our healthcare ecosystem. Let’s have a look at the most prominent use cases of artificial intelligence in medicine. Patient Prescreening Prescreening AI tools can add value even before patients visit medical facilities. Thus, intelligent algorithms can assist patients in self-monitoring and patients-at-home isolation, so that there is no rush and panic at clinics and hospitals. Today, prescreening boils down to standard questionnaires or online symptom checkers like WebMD. According to BMJ, these traditional pre-screening methods have a , while also inducing bias. wide range of accuracy On the contrary, extended AI-based functionality like voice recognition can ensure a more user-friendly experience than typical pre-screening questionnaires. Through machine learning, AI may also discover new patterns and detect patients' symptoms more correctly. A potential patient could describe symptoms through speech or text, just as they would to a doctor, thanks to natural language processing (where computers recognize text patterns). The patient and AI bot will exchange questions, replicating a real-life discussion between a doctor and a patient. Also, predictive analytics in healthcare helps to reduce patient admissions. In particular, it reduces preventable readmissions and predicts the possibility of developing a heart failure.[2] AI in Medical Imaging And Diagnostics According to the European Radiology Experimental’s poll, of global healthcare leaders project the impact of AI in monitoring and diagnosis to increase significantly. And there’s some good rationale behind it. more than half Over the last few years, artificial intelligence has gained momentum within the continuum of medical imaging and diagnostics, thus promoting higher accuracy for medical researchers and doctors. AI-enabled diagnostics r as well as shortens lab time and medical costs. eliminates human erro In particular, image recognition has the power to innovate medical diagnostics. Thus, medical imaging is the field that benefits the most from the adoption of smart systems. As such, medical imaging includes numerous radiological techniques. These may include: PET or positron emission tomography; CT or computed tomography; MRI or magnetic resonance imaging; Radiography, and others. AI can be used to discern advanced patterns in imaging data and yield quantitative analysis of radiographic characteristics. Thus, an AI-based technology developed by Lunit was employed in a undertaken by Korean academic hospitals to assist radiologists in mammography screenings. When radiologists applied AI, their accuracy jumped from 75.3 percent to 84.8 percent, according to the study. study Tumor delineation and treatment assessment are other widespread AI applications in radiation oncology. Drug Discovery Traditional drug discovery is a resource-consuming process that can go on for years. Thus, taking a drug from discovery to market can take up around and incur costs of over €2B. 10 to 12 years Luckily, artificial intelligence has gained traction in the drug research industry to ease the strain on the healthcare industry. According to MarketsandMarkets, AI in drug discovery accounts for a global market value of by 2024, up from $259 million in 2019. $1.434 billion Some of the flashy demonstrations of AI in biomedical research include the by Google’s AI subsidiary, DeepMind. It is said to yield computational predictions of protein structure that approach the quality of those provided by gold-standard experimental techniques such as X-ray crystallography. AlphaFold program In complex drug discovery, intelligent algorithms hold great potential to processes and make them more cost-effective, while also reducing the time a new drug requires to reach the patient. This superpower of artificial intelligence is attributed to its ability to comb through large datasets. The latter can include everything from clinical studies and scientific literature. accelerate research The algorithm then uncovers hidden patterns and relationships in data sets within mere seconds. Can manual efforts be on par with this speed? Sadly, no. Robot-assisted Surgery Once the protagonists of science fiction, robots have become a reality thanks to advanced AI capabilities. Today, robotic surgeries assist doctors in performing complex procedures with more precision and flexibility. For example, some robots guide surgeons when placing screws during spinal surgery.[3] Others simulate training and shadow surgeons during procedures that allow professionals to hone up their skills. However, the latter use case sparks up debates as robotics is cited as the . Wild West of surgical training Nevertheless, robotic surgery is an unseen generation of medical manipulation that aims to combine the strengths of technology and the human mind. Imagine a robot whose movements are controlled by a human. Isn’t it the dream of all sci-fi writers of the past? The proliferation of 5G networks is also carving out new possibilities for treatments using surgical robots. Thus, 5G facilitates remote surgery by instantly transmitting ultrahigh-resolution medical images of massive data size without delaying control signals. [4] This year, Kobe University, , and the Japanese telecommunications company NTT Docomo successfully performed a remote-surgery simulation using Docomo’s 5G network. Medicaroid Automated genome editing In 2020, Microsoft co-founder Bill Gates that advances in artificial intelligence and gene editing could accelerate the improvements of gene-based editing technologies. While we haven’t reached the equilibrium point in genome editing yet, the use of AI in this field bode well for identifying harmful genes and treating disease. stated Artificial neural networks are capable of identifying and revealing patterns in massive amounts of genetic data, thus detecting groups and sequences of genes associated with particular diseases. Also, machines can compute models to an individual’s odds of developing a condition, or where DNA might be changed to eradicate the disease. AI can also assess the impact of a gene mutation or evaluate possible treatments. predict Moreover, machine learning algorithms are also helpful in pinpointing where the alteration must be made and how to ensure the of the DNA strand afterward. proper repair Currently, artificial intelligence is used to boost the accuracy of a gene-editing technique called CRISPR-Cas. In particular, machine learning to predict the mutations that the tool is to introduce into the cells. helps Why Does It Take So Long Then? Although delivering clinical impact with AI is certainly promising, there are some clouds in the silver lining. Insufficient medical data is one of the challenges that await healthcare providers on the way to automation. Fragmented and unorganized health data haunts medicine and hampers effective training of AI algorithms. Healthcare data is often siloed in a wide range of medical imaging archival systems, , insurance databases, and others. Hence, this patchwork of information is hard to tie together. EHRs However, unified data formats like can augur better aggregation of data and enable automatic data retrieval from EHR. Fast Healthcare Interoperability Resources Moreover, a complex web of ingrained economic factors and ethical pitfalls also slow down the widespread adoption of healthcare automation. And let’s not forget legal barriers like the absence of AI standards in healthcare and the inability to be used in resource-poor settings. The Final Word The possibilities of artificial intelligence stretch across industries. Healthcare is among those fields that are benefiting the most from increased automation and hands-free processes. Artificial intelligence has the potential to fundamentally change the entire world of medicine. It can transform the diagnostic system, facilitate the development of new drugs, improve the quality of medical services, and reduce costs. However, since we haven’t overcome a multitude of AI limitations yet, the greatest disruption is still ahead (but we’re certainly moving in the right direction).
