Malnutrition, delirium, cancer – with all of these diagnoses, doctors in a New York hospital receive support from artificial intelligence. This is intended to provide better patient care and reduce the burden on doctors.
“The patient has a red flag” – DietitianCiana Scalia stands with her boss, Sara Wilson, in front of a flashing monitor in New York’s Mount Sinai. A red flag on the screen indicates a case of malnutrition. The computer is usually right. He spits out his diagnosis without the two having to type anything specific.”The program assembles the suspicion from all the indicators it can find in the patient’s medical records and history,” explains Scalia. Artificial intelligence automatically monitors the nutrition of all patients admitted to this Renowned hospital in East Harlem.Artificial intelligence in healthcare
Faster and more preciseartificial intelligence in healthcare
For five years, AI has been helping medical staff identify nutritional deficiencies in patients, develop a nutritional plan for them, and potentially speed up their recovery. The nutrition department director, Wilson, explains a procedure that would be much more time-consuming and bureaucratic if done conventionally. “We used to have to study the weight curves ourselves, the nutritional habits, laboratory results and much more – to develop a nutritional plan so patients can recover quickly.”
The AI would now do that – quickly. And much more precise than was previously possible, explains Scalia. “The algorithm can find things that we as human staff don’t even know we should be looking for, “she says. ” Because we don’t have that much time.”
Machines learn,artificial intelligence in healthcare.
Five years after the pilot began, her team is already filtering out three per cent more patients with malnutrition than before. The system is constantly improving, says Wilson. “At the moment, the accuracy is up to 70 per cent. But the machines are still learning.” They have to be constantly fed with data and with human intelligence.
Artificial intelligence always works with specialists from the clinic. They checked the computer information and at the same time fed the machine with their knowledge. However, the transparent patient needs to learn what the program is doing with his data. He sees no red flag. He only notices when nutritionist Scalia contacts him in the hospital room. Artificial intelligence in healthcare
However, clinic director David Reich sees this as acceptable: “It’s okay to check this without the patients’ knowledge. Because you’re just giving patients the right help at the right time.”That is the goal of the around 20 programs, with the oldest teaching hospital in the USA making itself the AI leader in New York and large parts of the USA, says Reich. “We started with the program formal nutrition, which often goes undetected in clinics. Then, one for the early detection of delirium. Another program calculates the risk of falls in patients.”
Time savings for doctors and nurses
The number of programs in use and now high-profile is constantly growing – with no reduction in human staff, emphasises Reich. Eight years ago, a team was founded at the clinic, which is larger than the Berlin Charité, with a name that the director jokes about: “The Little Big Data Group.”
Your task is to develop a system of algorithms that does not replace human staff but supports them and saves them a lot of time. Potentially life-saving time emphasizes neuroscientist Joseph Friedman. Ten years ago, he developed an AI program at the clinic that sounds the alarm before a patient falls into delirium and thus becomes an acute emergency – for example, after an operation. The colloquially known “fever madness” syndrome is very complex to diagnose. It is often difficult to recognize when the patient is losing the ability to think, can no longer stay awake, or behave differently significantly than usual. Intelligence in healthcare
The problem in almost all hospitals is that this syndrome needs to be treated promptly. Because it is difficult to predict the traditional way. The mortality rate is correspondingly high. With the help of the AI program, it is possible to quickly get the program and suggest a treatment plan.
Focus on high-risk cases.
Friedman remembers how different it was before the program existed. ” We were seeing maybe 100 patients a day just to find four to five people diagnosed with delirium.” To do this, huge amounts of data had to be studied, and each patient had to be personally examined.Valuable time for acute emergencies may have been lost.
Thanks to artificial intelligence, focusing directly on the patients at the highest risk is now possible. Friedman emphasizes that it’s not about saving doctors time but rather about allowing them to reach where they are most needed more quickly.
Regulation and review
Clinic director Reich is convinced that he is on the right path. “If you create a safer hospital environment, where malnutrition is treated at the same time and, therefore, a wound heals more quickly, where impending delirium is recognized, or the risk that a patient could fall—all of that only makes it better for the patient.”
He believes that artificial intelligence is not only changing doctors’ work but also requiring a rethink in their training. However, Reich also admits that the more artificial intelligence matures, the more important it is to regulate it. For example, there is the problem of structural racism in the USA. This should not be taken over by AI in healthcare.
“Poorer Americans – the majority of whom are Black, Hispanic or Indigenous – all have less access to medical care. So if you feed your algorithms with existing patient data, you risk them inheriting the biases of our medical system.”, explains Reich.
So, if the malnutrition prediction program doesn’t work well for African and Latin Americans, then work needs to be done on it. At Mount Sinai Hospital, they have set up an ethics committee to deal with such questions. All AI programs there are regularly checked for diseases.
Cancer Diagnosis Program
The control authorities in the USA have already approved around 400 AI systems in the clinical sector, explains Thomas Fuchs, director of the Hasso Plattner Institute for Digital Medicine – a branch of the Potsdam Institute at Mount Sinai Hospital. The Graz native is the master of the AIlaboratory, which receives a lot of data: In the entire system of the clinic and affiliated practices with almost 4,000 beds and around 7,400 medical employees, there are around 135,000 admissions per year – the emergency room and over 3.8 Millions of outpatients are not included.
The “Lab” is a sea of rushing computers in an unspectacular, bright room. This is where the heart of artificial intelligence beats in this hospital. Former NASA researcher Fuchs and his team are developing a cancer detection program. He proudly stands in front of the dull, hissing system. He beams: “We built our own supercomputer – the largest in the world for pathology -digitised millions of slices and then trained artificial intelligence over many months, which is good enough for it to be helpful for every patient.”
It can do this, for example, by recognizing and defining types of cancer and recording treatment paths. The program often sees better than a doctor alone can. “It can, for example, predict genetic mutations of the tumour based on the appearance of the tumour, says Fuchs. “And that then helps patients worldwide – not just in these ivory institutes -have access to the best diagnosis. ”
Artificial intelligence in healthcare, Criticism of regulation in Europe
In the end, it is always people who do it. The AI supports him in this. Fox warns against panic. Data protection is an important question, but the patient in need of help must also be protected. Restricting research leads to poorer treatment, less technology, and the falling behind of European research institutions in this area.
On the one hand, science funding leaves much to be desired in many European countries. “Austria spends about as much on AI research as Uganda,” says Fuchs. When it comes to regulation, however, European countries went overboard. “Of course, AI in healthcare needs regulation, but on the other hand, you can’t hinder research too much by making it very difficult to conduct research based on patient data.”
It is no coincidence that the Potsdam Institute conducts research using American data instead of from Berlin or Brandenburg. On the other hand, that simply means that the German systems cannot be optimized because they are outside this study. It’s a question of ethics that science does what it can, says Fuchs: “One thing is obvious these days when you talk about fears of AI: In medicine, patients die because there is no AI, not because there is AI exists.” artificial intelligence in healthcare
Artificial Intelligence (AI) is currently utilized to enhance efficiency and precision in various healthcare areas, and healthcare service providers are actively investigating numerous other uses for the technology. Insurers must be kept informed from the outset of the development of new tools to ensure that the healthcare provider will be safeguarded against the risk of a negative outcome leading to a claim.
AI applications
AI is applied to a broad range of tasks to enhance patient care, streamline operations, and advance medical research. In the field of diagnostics and imaging, AI can aid in the interpretation of medical images such as X-rays, magnetic resonance imaging (MRI ), and computed tomography (CT) scans to identify abnormalities and enable radiologists to make more precise diagnoses.
The technology can also facilitate the analysis of patient data, enabling researchers and healthcare providers to forecast disease outbreaks and patient readmissions. As illustrated in a presentation at the recent CFC Summit, ‘Incisions, instruments…internet(opens a new window)?’, some practitioners are also utilizing AI to monitor patient data in real time to identify signs of deterioration and to send alerts to early intervene.
Every area of healthcare presents unique challenges, and the speed at which AI applications can be developed will naturally differ. However, in the short-to-medium term, AI will be more widely deployed, especially in electronic health records management and to enhance administrative /operational efficiency.
Natural language processing tools can extract and organize information from unstructured clinical notes, making it simpler for healthcare providers to access pertinent patient data. Billing and claims processing can also be automated using AI, resulting in a decrease in errors. Both are already demonstrating positive indications of freeing up healthcare providers so that they are not bogged down by paperwork.
AI-powered opportunities in healthcare
- Early and more precise identification of diseases
- Cognitive technology can aid in unlocking large amounts of health data and facilitating diagnosis
- Predictive analytics can support clinical decision-making and actions
- Clinicians can take a broader approach to disease management
- Robots have the potential to transform end of life care
- Streamline the drug discovery and drug repurposing processes
- Naturalistic simulations for training purposes
- Technology applications and apps can promote healthier patient behavior, enable proactive lifestyle management, and capture data to improve understanding of patients’ needs
Risk considerations
But where there are opportunities there are also risks. AI is known to be prone to bias. The algorithms that underlie AI-based technologies have a tendency to mirror human biases in the data on which they are trained. As such, AI technologies have been known to produce consistently inaccurate results, which could painfully impact patients from specific groups.
AI-driven tools may also expose businesses to privacy and cyber security risks. In addition, a lack of human-like creativity and empathy may negatively impact the deployment of AI in a sensitive field like healthcare.
From an underwriter’s perspective, concerns about AI can vary depending on the specific use case, the size of the client concerned, and the regulatory environment.
Areas of lesser concern will likely include administrative enhancements, implementation of AI for clinical validation studies, data quality and governance, staff training and collaboration with healthcare professionals, as well as compliance with regulations. offline, direct-to-consumer chatbots diagnosing conditions, and secondary AI/machine learning tools to detect cancer will probably necessitate more detailed information.
If AI is utilized in a clinical setting, it is vital to ascertain if the tool’s algorithms have been clinically validated for efficacy and accuracy, to prevent misdiagnoses or incorrect treatment recommendations. Healthcare providers also need to be capable of explaining the ethical considerations and mitigation measures taken, particularly in relation to bias and fairness.
Patients, on the other hand, usually need to be informed before AI is used in their care and will need to provide consent.
Determining liability in cases of AI-related errors or adverse events poses a particular challenge to the healthcare sector. Healthcare providers, insurance brokers, and insurers need to work closely together to ensure that coverage is designed in a way that meets the healthcare provider’s needs and contractual obligations.
Although the liability landscape for healthcare providers utilizing AI is relatively untested, there are anonymized claims analytics and understand trends reports that can help to better the risks.
AI is playing an increasingly important role in the healthcare industry, aiding in diagnosis, improving processes, enhancing patient care, and saving lives. As technology advances, the opportunities are vast, from analyzing lab results and providing diagnosis to assisting with patient surgeries and correcting errors in drug administration.
Healthcare services face pressure due to record inflation and ongoing labor shortages, leading to long waiting lists in the UK’s National Health Service (NHS) and other public sector healthcare services globally. Utilizing AI could potentially reduce costs and redefine healthcare provision.
However, using advanced technology brings risks. It’s crucial to understand the potential applications of AI in healthcare and thoroughly test insurance programs to ensure adequate protection.
Mentions of AI have become common in the healthcare industry. Deep learning algorithms can read CT scans faster than humans, and natural language processing can analyze unstructured data in electronic health records (EHRs).
Despite the potential benefits of AI, there are also concerns about privacy, ethics, and medical errors.
Achieving a balance between the risks and rewards of AI in healthcare will require collaboration among technology developers, regulators, end-users, and consumers. Addressing the contentious discussion points is the first step in considering the adoption of complex healthcare technologies.
AI will challenge the status quo in healthcare, changing patient-provider relationships and affecting the role of human workers.
While some fear that AI will eliminate more healthcare jobs than it creates, recent data suggests healthcare jobs are projected to remain stable or even grow.
Nevertheless, concerns remain as AI tools continue to show superior performance, particularly in imaging analytics and diagnostics. Radiologists and pathologists may be particularly vulnerable to automation by AI.
In a report from 2021, researchers at Stanford University evaluated the progress of AI in the past five years to observe changes in perceptions and technologies. The researchers discovered that AI is being increasingly used in robotics, gaming, and finance.
The technologies that underpin these significant advancements are also being applied in the field of healthcare. This has led some physicians to worry that AI might eventually replace them in medical practices and clinics. However, healthcare providers have varied opinions about the potential of AI, with some cautiously optimistic about its impact.
According to the report, in recent years, AI-based imaging technologies have transitioned from being solely academic pursuits to commercial projects. There are now tools available for identifying various eye and skin disorders, detecting cancers, and facilitating the measurements required for becoming clinical diagnosis .
The report stated that some of these systems can match the diagnostic capabilities of expert pathologists and radiologists. They can also assist in alleviating arduous tasks, such as counting the number of cells dividing in cancerous tissue. Nevertheless, the use of automated systems in other areas raises significant ethical concerns.
Simultaneously, one could argue that there is an inadequate number of radiologists, pathologists, surgeons, primary care providers, and intensivists to meet the existing demand. The United States is grappling with a critical shortage of physicians, particularly in rural areas, and this shortage is even more severe in developing countries worldwide.
AI might also aid in reducing the burdens that contribute to burnout among healthcare workers. Burnout affects a majority of physicians, as well as nurses and other care providers, leading them to reduce their working hours or opt for early retirement rather than persisting through unfulfilling administrative tasks.
Automating certain routine tasks that consume a physician’s time – such as electronic health record (EHR) documentation, administrative reporting, or even the triage of CT scans – can enable humans to focus on the complex challenges posed by patients with rare or serious conditions.
The majority of AI experts anticipate that a combination of human expertise and digital augmentation will be the natural equilibrium for AI in healthcare. Each form of intelligence will contribute something valuable, and both will collaborate to enhance the delivery of care.
Some have raised concerns that healthcare professionals may become overly reliant on these technologies as they become more prevalent in healthcare settings. However, experts emphasize that this outcome is unlikely, as the issue of automation bias is not new in healthcare, and there are existing strategies to mitigate it.
Patients also appear to hold the belief that AI will ultimately improve healthcare, despite some reservations about its utilization.
A research letter published in JAMA Network Open last year, which surveyed just under 1,000 respondents, found that over half of them believed that AI would either somewhat or significantly improve healthcare. Nevertheless, two-thirds of the respondents indicated that being informed if AI played a major role in their diagnosis or treatment was very important to them.
Concerns about the use of AI in healthcare seem to vary somewhat by age. However, research conducted by SurveyMonkey and Outbreaks Near Me – a collaboration involving epidemiologists from Boston Children’s Hospital and Harvard Medical School – indicates that, generally, patients prefer important healthcare tasks, such as prescribing pain medication or diagnosing a rash, to be carried out by a medical professional rather than an AI tool.
Regardless of whether patients and providers are comfortable with the technology, AI is making strides in healthcare. Many healthcare systems are already implementing these tools across a wide range of applications.
Michigan Medicine utilized ambient computing, a type of AI designed to create a responsive environment to human behaviors, to enhance its clinical documentation improvement efforts during the COVID-19 pandemic.
Researchers at Mayo Clinic are pursuing a different AI approach: they intend to leverage the technology to enhance organ transplant outcomes. Currently, these efforts are concentrated on developing AI tools to avoid the need for a transplant, enhance donor matching, increase the number of viable organs, prevent organ rejection, and improve post-transplant care.
AI and other data analytics tools can also play a critical role in population health management. Effectively managing population health necessitates that healthcare systems utilize a combination of data integration, risk stratification, and predictive analytics tools. Care teams at Parkland Center for Clinical Innovation (PCCI ) and Parkland Hospital in Dallas, Texas are utilizing some of these tools as part of their program to address disparities in preterm birth.
Even though AI has great potential in healthcare, incorporating this technology while safeguarding privacy and security is quite challenging.
CHALLENGES WITH AI PRIVACY AND SECURITY
The use of AI in healthcare brings about a whole new set of difficulties regarding data privacy and security. These challenges are further complicated by the fact that most algorithms require access to extensive datasets for training and validation purposes.
Transferring huge volumes of data between different systems is unfamiliar territory for most healthcare organizations. Stakeholders are now fully aware of the financial and reputational risks associated with a high-profile data breach.
Most organizations are advised to keep their data assets tightly secured in highly protected, HIPAA-compliant systems. With the surge in ransomware and other cyberattacks, chief information security officers are understandably hesitant to allow data to move freely in and out of their organizations.
Storing large datasets in a single location makes that repository a prime target for hackers. Apart from AI being a tempting target for threat actors, there is an urgent need for regulations pertaining to AI and the protection of patient data using these technologies.
Experts warn that safeguarding healthcare data privacy will require updating existing data privacy laws and regulations to encompass information used in AI and ML systems, as these technologies can potentially re-identify patients if data is not adequately de-identified.
However, AI falls into a regulatory gray area, making it challenging to ensure that every user is obligated to protect patient privacy and will face repercussions for failing to do so.
In addition to more traditional cyberattacks and patient privacy concerns, a study by University of Pittsburgh researchers in 2021 revealed that cyberattacks using manipulated medical images could deceive AI models.
The study shed light on the concept of “adversarial attacks,” where malicious actors seek to alter images or other data points to cause AI models to reach incorrect conclusions. The researchers trained a deep learning algorithm to accurately identify cancerous and benign cases over 80 percent of the time.
Subsequently, they developed a “generative adversarial network” (GAN), a computer program that creates false images by displacing cancerous regions from negative or positive images to confuse the model.
The AI model was fooled by 69.1 percent of the falsified images. Out of 44 positive images made to look negative, the model identified 42 as negative. Moreover, out of 319 negative images doctored to appear positive, the AI model classified 209 as positive.
These findings demonstrate the possibility of such adversarial attacks and how they can lead AI models to make an incorrect diagnosis, posing potential significant patient safety issues.
The researchers emphasized that understanding how healthcare AI behaves under an adversarial attack can help health systems better understand how to make models more secure and resilient.
Patient privacy may also be at risk in health systems employing electronic phenotyping through algorithms integrated into EHRs. This process aims to flag patients with specific clinical characteristics to gain better insights into their health and provide clinical decision support. However, electronic phenotyping can lead to a range of ethical concerns regarding patient privacy, including inadvertently revealing undisclosed information about a patient.
Nevertheless, there are methods to safeguard patient privacy and provide an additional layer of protection to clinical data, such as privacy-enhancing technologies (PETs). Algorithmic, architectural, and augmentation PETs can all be utilized to secure healthcare data.
While security and privacy will always be critical, the fundamental shift in perspective as stakeholders become more accustomed to the challenges and opportunities of data sharing is crucial for fostering the growth of AI in a health IT ecosystem where data is segregated and access to quality information is one of the industry’s most significant hurdles.
ETHICS, RESPONSIBILITY, AND OVERSIGHT
The most challenging issues in the AI debate are the philosophical ones. Apart from the theoretical questions about who bears the ultimate responsibility for a life-threatening error, there are concrete legal and financial ramifications when the term “malpractice” enters the picture.
Artificial intelligence algorithms are inherently intricate. As the technology advances, it will become increasingly difficult for the average individual to comprehend the decision-making processes of these tools.
Organizations are currently grappling with trust issues when it comes to following recommendations displayed on a computer screen, and providers find themselves in the predicament of having access to vast amounts of data but lacking confidence in the available tools to help them navigate through it.
Although some may believe that AI is entirely free of human prejudices, these algorithms will learn patterns and produce results based on the data they were trained on. If this data is biased, the model will also be biased.
There are currently limited reliable methods to identify such biases. The problem is further complicated by “black box” AI tools that provide little explanation for their decisions, making it challenging to attribute responsibility when things go wrong.
When providers are legally accountable for any negative consequences that could have been foreseen from the data in their possession, it is crucial for them to ensure that the algorithms they use present all relevant information in a way that facilitates optimal decision-making.
However, stakeholders are working on establishing principles to address algorithmic bias.
In a report from 2021, the Cloud Security Alliance (CSA) recommended assuming that AI algorithms contain bias and working to recognize and mitigate these biases.
The report stated, “The increased use of modeling and predictive techniques based on data-driven approaches has revealed various societal biases inherent in real-world systems, and there is growing evidence of public concerns about the societal risks of AI.”
“Identifying and addressing biases in the early stages of problem formulation is a crucial step in enhancing the process.”
The White House Blueprint for an AI Bill of Rights and the Coalition for Health AI (CHAI)’s ‘Blueprint for Trustworthy AI Implementation Guidance and Assurance for Healthcare’ have also recently provided some guidance for the development and deployment of trustworthy AI, but these efforts have limitations.
Developers may unintentionally introduce biases into AI algorithms or train the algorithms using incomplete datasets. Nevertheless, users must be mindful of potential biases and take steps to manage them.
In 2021, the World Health Organization (WHO) published the first global report on the ethics and governance of AI in healthcare. WHO underscored the potential health disparities that could arise due to AI, especially because many AI systems are trained on data gathered from patients in affluent healthcare settings.
WHO recommends that ethical considerations should be integrated into the design, development, and deployment of AI technology.
Specifically, WHO suggested that individuals working with AI adhere to the following ethical principles:
- Protecting human autonomy
- Promoting human well-being and safety, as well as the public interest
- Ensuring transparency, explainability, and intelligibility
- Fostering responsibility and accountability
- Ensuring inclusiveness and equity
- Promoting AI that is responsive and sustainable
- Bias in AI is a significant issue, but one that developers, healthcare professionals, and regulators are actively endeavoring to address.
It will be the responsibility of all stakeholders – providers, patients, payers, developers, and everyone in between – to ensure that AI is developed ethically, safely, and meaningfully in healthcare.
There are more questions to tackle than anyone could possibly imagine. However, unanswered questions are a reason to keep exploring, not to hold back.
The healthcare ecosystem has to start somewhere, and “from scratch” is as good a place as any.
Defining the industry’s approaches to AI is a significant responsibility and a great opportunity to avoid some of the mistakes of the past and pave the way for a better future.
It’s an exhilarating, bewildering, exasperating, hopeful time to be in healthcare, and the ongoing advancement of artificial intelligence will only add to the mix of emotions in these ongoing discussions. There may not be clear answers to these fundamental challenges at this moment, but humans still have the chance to take charge, make tough decisions, and shape the future of patient care.
Artificial Intelligence (AI) has increasingly become significant in the world over the last few decades. Many may not realize that AI exists in various forms that influence everyday life. A key area where AI is expanding is in healthcare, particularly in diagnostics and treatment management. While there are concerns about AI potentially overtaking human roles and capabilities, extensive research indicates how AI can assist in clinical decision-making, enhance human judgment, and improve treatment efficiency.
Growing Presence of AI in Healthcare
AI has various levels of involvement in healthcare. Often, AI leverages an online database, enabling healthcare providers to access numerous diagnostic tools. Given that doctors are highly trained in their specialties and current with recent findings, AI significantly accelerates outcomes that complement their clinical expertise.
On the other hand, there are anxieties regarding AI eventually replacing or diminishing the need for human doctors, especially in clinical environments. However, recent research and data suggest that this technology is more likely to enhance and complement clinical diagnostics and decision-making than to decrease the necessity for clinicians.
Patients frequently exhibit multiple symptoms that may relate to several conditions based on genetic and physical traits, which can delay diagnoses. Consequently, AI aids healthcare professionals by increasing efficiency and providing quantitative and qualitative data based on feedback, resulting in improved accuracy in early detection, diagnosis, treatment planning, and outcome forecasting.
AI’s capacity to “learn” from data allows for better accuracy based on feedback received. This feedback consists of various backend database sources and contributions from healthcare providers, physicians, and research institutions. AI systems in healthcare operate in real-time, which means the data is continuously updated, enhancing accuracy and relevance.
The assembled data encompasses a variety of medical notes, recordings from medical devices, laboratory images, physical exams, and diverse demographic information. With this vast and constantly updated information pool, healthcare professionals have nearly limitless resources to enhance their treatment capabilities.
Consequences of AI for the Healthcare Workforce
AI is projected to significantly influence the healthcare workforce. As AI-driven applications evolve in complexity, they will play an increasingly vital role in patient care. This will lead to a transformation in healthcare delivery, with a greater focus on preventive care and early intervention. This change will necessitate a different skill set among healthcare professionals who will need to have a better grasp of data and analytics. Additionally, they will need to feel at ease working with AI-supported applications.
The effects of AI on the healthcare workforce will be extensive. It is important to begin preparing now for the forthcoming changes. Organizations in healthcare should consider how AI can enhance patient care and improve the efficiency of the healthcare system. They should also contemplate how to retrain their workforce to adapt to future needs.
The Prospects of AI in Healthcare
The potential future of AI in healthcare is promising. As AI-driven applications advance, they will bring about several changes in how healthcare is administered. A transition will occur from reactive to proactive care, focusing more on prevention and early intervention.
AI will also revolutionize how healthcare professionals engage with patients. Rather than providing a one-size-fits-all approach to care, AI will enable them to offer personalized treatment tailored to individual patients. This will lead to improved health outcomes and a more efficient healthcare system.
Healthcare providers are only beginning to explore the possibilities AI offers. As more advanced AI-driven applications emerge, even more transformative changes in healthcare will become apparent. The potential of AI is boundless.
AI Offers More Accurate Diagnostics
Given the extensive healthcare data available, AI must effectively navigate this data to “learn” and create connections. In the realm of healthcare, there are two categories of data that can be processed: unstructured and structured. Structured learning employs three techniques: Machine Learning (ML), a Neural Network System, and Modern Deep Learning. In contrast, non-structured data utilizes Natural Language Processing (NLP).
Machine Learning Techniques (ML)
Machine Learning techniques employ analytical algorithms to extract specific patient characteristics, including all the information gathered during a patient visit with a healthcare provider. These characteristics, such as results from physical examinations, medications, symptoms, basic metrics, disease-specific data, diagnostic imaging, genetic information, and various lab tests all contribute to the collected structured data.
By employing machine learning, outcomes for patients can be assessed. A particular study applied Neural Networking in the process of diagnosing breast cancer, analyzing data from 6,567 genes along with texture information derived from the subjects’ mammograms. This integration of recorded genetic and physical traits enabled a more accurate identification of tumor indicators.
Neural Networks & Contemporary Deep Learning
In clinical environments, supervised learning is the most prevalent form of Machine Learning. This method utilizes a patient’s physical characteristics, supported by a database of information (in this instance, breast cancer-related genes), to deliver more targeted results. Another approach that is employed is Modern Deep Learning, which is regarded as an advancement over traditional Machine Learning.
Deep Learning utilizes the same input as Machine Learning but processes it through a computerized neural network, generating a hidden layer that simplifies the data into a more straightforward output. This assists healthcare professionals in narrowing down multiple potential diagnoses to one or two, allowing them to reach a more conclusive and definite determination.
Natural Language Processing (NLP)
Natural Language Processing operates similarly to structured data techniques but focuses on all unstructured data within a clinical context. Such data can originate from clinical notes and speech-to-text documentation recorded during patient encounters. This includes narratives derived from physical examinations, laboratory assessments, and examination summaries.
Natural Language Processing leverages historical databases filled with disease-related keywords to facilitate the decision-making process for diagnoses. Employing these techniques can lead to more precise and efficient patient evaluations, ultimately saving practitioners time and accelerating treatment. The more rapid and specific a diagnosis is, the sooner a patient can begin their recovery journey.
AI can be integrated across significant disease domains
Given that cardiovascular diseases, neurological disorders, and cancer remain the leading causes of mortality, it is crucial to maximize the resources available to support early detection, diagnosis, and treatment. The introduction of AI enhances early detection by identifying potential risk indicators for patients.
Let’s explore some instances of AI applications in key disease fields:
Early stroke detection
In one study, AI algorithms were used with patients at risk of stroke, taking into account their symptoms and genetic backgrounds, which allowed for early identification. This process focused on documenting any abnormal physical movements, triggering alerts for healthcare providers. Such alerts enabled faster access to MRI/CT scans for disease evaluation.
The early detection alerts from the study achieved a diagnostic and prognostic accuracy of 87.6%. Consequently, this allowed healthcare providers to initiate treatment sooner and forecast patients’ likelihood of future strokes. Moreover, machine learning was utilized for patients 48 hours post-stroke, yielding a prediction accuracy of 70% regarding the risk of another stroke.
Forecasting kidney disease
The Department of Veterans Affairs and DeepMind Health accomplished a significant milestone in 2019 by developing an AI tool capable of predicting acute kidney injury up to 48 hours earlier than conventional methods.
Acute kidney disease can rapidly lead to critical health crises and is notoriously difficult for clinicians to detect. This innovative approach to predicting and detecting acute kidney issues empowers healthcare practitioners to recognize potential renal disease risks long before they manifest.
Cancer research and treatment
AI has also made substantial contributions to cancer research and treatment, especially in the field of radiation therapy. Historically, the absence of a digital database in radiation therapy has posed challenges in cancer research and treatment efforts.
In response, Oncora Medical created a platform designed to support clinicians in making well-informed choices regarding radiation therapy for cancer patients. This platform aggregates patient medical data, assesses care quality, optimizes treatment strategies, and supplies insights on treatment outcomes, data, and imaging.
Predictive analytics
CloudMedX, a healthcare technology firm, launched an AI solution transforming electronic health records into a smart predictive instrument, aiding clinicians in making more precise decisions. This tool assists healthcare providers in detecting and managing medical conditions before they escalate into life-threatening situations by analyzing a patient’s medical history and correlating symptoms with chronic diseases or familial conditions.
AI is increasingly being utilized in applications focused on patient engagement and adherence. It is widely recognized that enhanced patient participation in their health leads to improved outcomes, making engagement a critical challenge in healthcare. AI-enabled applications can aid patients in adhering to their treatment plans by offering personalized advice and reminders, thereby enhancing health results.
Moreover, AI can aid in the early identification of possible adherence issues. Through the analysis of patient behavior, AI-powered applications can deliver insights that enable healthcare teams to act before non-adherence escalates into a larger issue. By utilizing AI to boost patient engagement and compliance, healthcare providers can enhance health outcomes and streamline the efficiency of the healthcare system.
Obstacles to Adoption
Even with the clear benefits of AI in healthcare, its implementation has been slow. According to a study by the Brookings Institute, four main obstacles impede AI adoption in healthcare: limitations in data access, algorithmic challenges, misaligned incentives, and regulatory hurdles.
Data access limitations
A primary obstacle to AI integration in healthcare is the scarcity of data. For AI-driven applications to perform effectively, they must have access to extensive data sets. Unfortunately, many healthcare organizations lack the required data resources. To address this challenge, these organizations need to invest in data gathering and management.
Algorithmic limitations
Algorithms are dependent on the quality of the data used for training. Some intricate algorithms can complicate healthcare professionals’ understanding of how AI arrives at specific recommendations.
This lack of transparency can have serious consequences in healthcare, where AI assists in making patient care choices. Trust in this technology is crucial, especially since healthcare providers are held responsible for decisions influenced by the AI tools they employ.
Misalignment of incentives
The extent of AI adoption varies among health systems, influenced by the attitudes of hospital leadership and individual decision-makers. Some hospitals led by physicians may hesitate to embrace AI due to concerns it might replace them, while those managed by administrators tend to be more receptive to its application in non-clinical functions.
Regulatory barriers
The healthcare sector is highly regulated, yet there are no definitive guidelines governing the use of AI, resulting in considerable uncertainty. Many healthcare organizations also hesitate to share data with AI applications for fear of violating patient confidentiality. While this concern is legitimate, it should not serve as a pretext for hindering the application of AI in healthcare.
These challenges can be resolved with a joint effort from all involved parties. Regulators in healthcare need to formulate clear directives on AI usage, while healthcare organizations must confront their data privacy and security worries.
Enhanced Diagnostics and Treatment Planning
A significant function of AI in healthcare is its capability to process extensive data and spot patterns and trends. This ability allows healthcare providers to deliver precise diagnoses and create tailored treatment strategies. AI-powered technologies can assess medical images, like X-rays and MRIs, with great precision, promoting early disease detection and swift action. Additionally, AI algorithms can help interpret lab results, identifying irregularities and suggesting areas for further examination. By leveraging AI for diagnostics, healthcare professionals can enhance the accuracy and timeliness of diagnoses, ultimately resulting in improved patient outcomes.
Automated Administrative Tasks
AI has also transformed administrative functions within healthcare. Utilizing AI-powered systems enables healthcare professionals to automate tedious tasks, such as scheduling appointments and managing medical records. This automation allows healthcare providers to dedicate more time to patient care and reduces the likelihood of human error.
