Top Smart Algorithms In Healthcare

We made a list of the best AI algorithms to help us keep track of their progress in improving diagnostics, patient care, and disease prediction.

Does AI beat doctors?

You would have to have been living under a stone for the past couple of years not to have heard of artificial intelligence in healthcare. The hype surrounding AI and smart algorithms has increased tremendously. Newsreaders will see headlines that say “AI beat doctors in field X“.

Elon Musk, Stephen Hawking and others have warned that this is the case. Or artificial intelligence can be portrayed as either the greatest evil that will destroy mankind or as the source of future prosperity for humanity.

Think of the recent open letter controversy and the way that fears were fueled by the public despite the opposition of the greatest minds who called for a nuanced approach.

We also want to include what we think is already helpful for medical professionals.

Life Is No Training Data Set

Before we list them, let’s go through each one. The term AI is already misleading, as it implies that the technology is far more advanced than what is currently available. Current science, which includes large language models and machine learning, can only reach artificial narrow intelligence in multiple fields. This is the first level intelligence created by humans.

We are still far from reaching artificial general intelligence (AGI), the second level in intelligence, when a machine can abstract concepts from limited experiences and transfer knowledge across domains. Superintelligence, the third and most feared domain, where AI evolves to a self-contained consciousness, is still a long way off.

ANI, its two main streams of computer vision and natural language processing are growing at an astonishing rate. Pattern recognition is the basis of this technology, which is vital for healthcare diagnostics. Numerous algorithms are being trained to recognize patterns in medical images, which can help diagnose diseases.

At least three limitations are evident in such studies. The first is that the medical evidence used tends to come from highly developed areas, containing their own specificity. Or the framework of conceptualizing the algorithm incorporates the subjective assumptions made by the team. Second, smart algorithms’ forecasting and prediction abilities are based on previous cases. However, they may be useless for new cases of side effects of drugs or resistance to treatment.

After the algorithm analyzes the images, doctors receive the same dataset, usually without reproducing clinical conditions.

This does not diminish the theoretical value, but rather its practical application. The real world is not a training data set. Patients with similar symptoms or conditions can describe them very differently. The results of AI research conducted on training data may not reflect what will happen in actual situations. These limitations are often not included in common interpretations, which focus on portraying these studies as the ultimate truth.

Here are the top AI algorithms we found recently in healthcare, keeping all of these constraints in view.

The algorithm for detecting DNA mutations in cancer

It’s difficult to treat cancer because malignant tumors are prone to grow, change, and evolve. Scientists discovered in recent years that cancer’s DNA also undergoes transformation. The genetic analysis of tumors has become possible as sequencing costs have significantly decreased. Recently, experts using computational tools began to analyze data to determine what types of genetic changes or mutations occur.

[TAG1]

Personal Genome Diagnostics, based in Baltimore, developed a method that uses machine learning to automate the tumor DNA diagnosis process. This improves the accuracy in identifying mutations within cancerous tissue. The doctor can then choose the best treatment for each patient based on the results.

2) Can AI classify heart images better than humans?

The echocardiogram uses sound waves to create a picture of the heart. This allows cardiologists to determine if the patient is suffering from heart disease. This is a standard test that checks for heart problems, such as valve or chamber issues or congenital defects. It can also be used to determine if chest pain or shortness of breathe are related to the heart.

Researchers at Cedars Sinai’s Smidt Heart Institute, Division of Artificial Intelligence in Medicine have made a fascinating discovery in this area. The researchers reported that AI was more effective in diagnosing and assessing cardiac function than echocardiogram assessments performed by sonographers. This first blinded, randomized trial compared the initial assessment of 3,495 transthoracic ultrasound studies by sonographers and artificial intelligence. The major finding was that the cardiologists agreed more often with the AI’s initial assessment. They corrected only 16.8% and 27.2% respectively of the AI’s initial assessments.

This was not the only initiative to use AI for cardiology. Rima Arnaut is an assistant professor at UC San Francisco, and a practicing cardiologist. She and her colleagues trained an AI system to classify echocardiograms based on the type of view. The algorithm was able to achieve a 92 percent accuracy when both AI and cardiologists were asked sort the images. Humans only got 79 percent of the images right.

3) Heart attack prediction algorithms

Smart algorithms are superior to doctors in terms of classifying and predicting outcomes. Researchers from the University of Nottingham, UK, created a system to scan patients’ medical records and predict which of them will have a stroke or heart attack within the next 10 years. The AI system accurately predicted 355 more patients than the standard method based on established risk factors like high blood pressure and cholesterol.

Many promising initiatives are being undertaken in this area. Some aim to predict heart attacks many years in advance. Another distinguishes between treatable or untreatable cardiac arrests. This algorithm is designed to detect heart attacks more accurately in women who often go undetected in standard circumstances.

AI allows for more precise diagnosis of skin cancer

The WHO reports that around 325,000 melanoma and 1.5 million non-melanoma cases of skin cancer occur every year in the world. AI and digital health technologies such as SkinVision, telemedical service, and smartphone apps are the most effective in combating the disease.

[TAG2][TAG7]

Stanford University’s smart algorithm for skin cancer diagnosis is the most advanced system to date. The system was fine-tuned using a collection of 130,000 skin lesions scanned from over 2000 diseases. It was trained with more than 1,28 million images. This is the largest dataset for skin cancer classification.

5) Artificial Intelligence Systems for the ICU

The intensive care units are battlefields where human lives are at stake. Patients are constantly monitored by an army of devices, as every second counts. Bedside monitors constantly beep to show vital signs such as blood pressure and heart rate. Another machine is responsible for monitoring the heart. These instruments are not usually connected. They are separate units that are used in concert to provide ICU care.

AI for breast cancer detection

Breast cancer is second in terms of cancers that affect women, and third overall. Despite global efforts to raise awareness and prevent new cases, there were more than 2 million in 2020. Statistics show that in 2020, almost 700 000 women will die from breast cancer.

[TAG3]

Early detection is crucial for many cancer types. Women with dense breasts are more likely to have mammograms miss breast cancer signs. Researchers from the University of California San Francisco discovered that commercial software used to automatically classify breast density, and detect breast cancer, is as accurate as radiologists. The algorithm will soon be able to help doctors in cases where breast density does not allow for a clear diagnosis.

Not only radiologists, but also pathologists could benefit from algorithms in the fight against breast cancer. The International Symposium on Biomedical Imaging held a challenge to evaluate the computational systems used for automated detection of metastatic cancer. The winning study revealed that by combining the efforts and predictions of the deep learning system with the human pathologist, the human error rate for identifying metastatic cancer decreased by 85 per cent.

This is an impressive result. It’s especially impressive when you consider that early diagnosis can save lives in the case of lethal diseases. It is also worth noting that AI and doctors working together showed a significant improvement, even though their individual results were not close.

AI has been used in Hungary since 2021. Five hospitals and clinics perform over 35,000 screenings per year. AI systems now check for cancer signs that radiologists may have missed.

7) A smart algorithm for predicting suicide risks

You might be sent to the hospital for a broken arm, and then leave with a cast. The note will also state that a mandatory psychiatry appointment is required due to a flagged suicide threat. Scientists are aiming to achieve this with an AI system designed to detect depressive behavior early and reduce the emergence or severe mental illness.

The algorithm, developed at Vanderbilt University Medical Center, Nashville, is based on data from hospital admissions, such as age, gender and zip code. It also includes information about medication and diagnostic history. The algorithm, which was tested on data from over 5,000 patients admitted to hospital for self-harm and suicide attempts or who were also admitted due to self-harm, predicted suicide attempts 84% of the time. It was also 80% accurate in predicting suicide attempts within two years.

8) AI predicting death risk among inpatients

Stanford University researchers trained an AI system that can predict when patients nearing death are very seriously ill.

The algorithm was taught to analyze demographics, prescriptions and other factors in electronic health records within the 3-12 month period prior to a patient’s death. The algorithm, once trained, was able flag still-living hospital patients who might be suitable candidates for palliative treatment. Stanford Hospital’s Palliative Care team evaluated 50 randomly selected patients who were flagged by the algorithm as having a very high level of risk. The team concluded that they all should be referred. The program was able to predict accurately, but it also left the decision-making entirely in the hands the doctors. This could be the future of algorithms and doctors working together.

MedPaLM is the large medical language model

The large language models have undoubtedly changed the field for ever. They are capable of providing such high-quality support that has never been seen before. Google/DeepMind released MedPaLM a few weeks after ChatGPT. It is a large-language model designed specifically to answer healthcare questions.

[TAG5]

The model was trained using six existing datasets of medical Q&A questions (NedQA MedMCQA PubMedQA LiveQA MedicationQA and MMLU) and also the HealthSearchQA created by the developer teams, which included questions on medical conditions and their symptoms. MedPaLM is not available for public testing at this time, but the researchers’ paper can be read here.

Google has also recently launched the latest version and provided access to select users. However, we haven’t yet seen any studies relating to the 2.0.

10) Sepsis-watching algorithm

Researchers at Duke University developed a Sepsis Watch algorithm, which uses deep learning to assess the risk of sepsis in a patient. The algorithm alerts the rapid response team of the hospital in the case of high-risk patients and guides them during the first three hours of care. It is crucial to preventing complications. This algorithm has been developed by the university for many years. The model was implemented in clinical work during 2018. Mark Sendak is a Duke physician and clinical data scientists who led the project. Duke is currently conducting a final evaluation, but Mark noted that mortality appears to be on the decline.

The hospital chain HCA Healthcare has also developed an algorithm for predicting sepsis and optimising therapy. The algorithm continuously monitors data from patients to identify potential sepsis. The algorithm can detect sepsis up to six hours earlier than clinicians. This allows the health care system in 160 hospitals to reduce sepsis deaths by almost 30%.

[TAG6]

AI is our new friend.

Many more examples of smart algorithms will be available in the future. The last example, however, encapsulated the essence of digital healthcare: the best results come from the collaboration between artificial intelligence and doctors.

Artificial intelligence (AI), which is poised to revolutionize medical practice, requires that medical students, young doctors and practicing doctors be prepared for this new landscape. Rapid advancements in AI has led to a paradigm shift.

I’ve said it before and will say it again: AI won’t replace doctors. But doctors who use AI will replace those doctors who don’t keep up with the revolution. The integration of AI into medical practice is not only beneficial to patients, but will also boost the career of doctors who are prepared for this new age of medicine.

Frequently Asked Questions

Is holistic medicine legitimate?

Both yes and no. Yes. There are many medications that have been proven to be effective against various conditions. They don’t cure all ailments. It all depends what you mean “holistic.” It all depends on what you mean by “holistic.”

Some claim holistic medicine was around since ancient times. But this is simply untrue. Although there were some natural remedies used by healers in ancient Egypt or Rome, these practitioners did not have scientific knowledge.

It wasn’t until after the Middle Ages that medical doctors began to study anatomy. Most Western countries had established public hospitals in which trained doctors could offer medical care by the turn of the 19th century.

Conventional medicine has become the dominant form for healthcare. However, many still prefer to use alternative and complementary medicine. Many find that it works better for them than pharmaceutical drugs.

Some people find that they feel more relaxed when receiving massage therapy than tranquilizers. Many people prefer eating healthy foods to taking prescription drugs. Others still believe that regular exercise improves their bodies’ performance.

What is Alternative Medicine?

This is a holistic approach to healing that emphasizes prevention over treatment. It encourages people be educated consumers, actively participating in their own health and well being.

Alternative medicine refers to any system of diagnosis and treatment that does not employ allopathic (conventional) medical practices.

What is a holistic medicine doctor?

A holistic medicine doctor is someone who treats patients holistically. They might combine western medicine and traditional methods, such as acupuncture and herbs.

They are not interested in treating symptoms but rather a disease. After treatment, the patient should feel better.

The doctor should not only treat the disease, but also prevent it from happening again.

“Holistic” is a term that refers all aspects of a person’s life.

Complementary and Alternative Healthcare – Is it Evidence-based

The evidence base supporting complementary and alternate medicine is still developing, but there are many factors that people choose to use these therapies. They might have tried other treatments, but they were ineffective. Or they may prefer to try alternative therapies because they offer more benefits than traditional care. Alternative and complementary medicine may be an option. This is part of a holistic approach. It is important for patients to verify that any alternative or complementary medicines they are using have been supported by scientific research. If you’re unsure whether a particular treatment is effective, ask your doctor or pharmacist. It will save you time and money over the long-term.

Statistics

The use of alternative medicine in the US has increased, with a 50 percent increase in expenditures and a 25 percent increase in the use of alternative therapies between 1990 and 1997 in America. (en.wikipedia.org)
An assessment of conventional treatments found that 41.3% concluded positive or possibly positive effects, 20% concluded no effect, 8.1% concluded net harmful effects, and 21.3% concluded insufficient evidence. (en.wikipedia.org)
According to a 2005 book by a US [116]Institute of Medicine panel, the number of RCTs focused on CAM has risen dramatically. (en.wikipedia.org)
According to the World Health Organization, 80% of people use herbal medicine worldwide. (webmd.com)
In the 17% in which they disagreed, a third reader agreed with one of the initial readers to set a rating. (en.wikipedia.org)

How To

What are the 4 types of complementary or alternative medicine?

The main four categories of CAM include mind-body medicines, natural products and manipulative therapy. Mind-body Medicine includes Tai Chi, Reiki (tai chi), yoga, massage therapy, homeopathy and aromatherapy. Natural products can include herbs, vitamins and minerals, dietary supplement, and botanicals. Manipulative therapies can include physical manipulations such as acupuncture, chiropractic care, and osteopathic/chiropractic care. You can also use prayer and visualization to help you heal your energy.

CAM refers to a variety of health practices that are not in line with Western medical models. The scientific evidence supporting these practices is varied, as are the types of drugs they use and what conditions they treat. Some CAM doctors also provide diagnostic testing (e.g. Blood tests) and can prescribe medication. Others may do neither.

In addition to these four primary categories, there are many subcategories within each category. Mind-body medicine is comprised of relaxation techniques, mindfulness, guided imagery and self-hypnosis. There are also deep breathing exercises, meditations, progressive muscle relaxation, stress management, biofeedback and visualization. Natural products include nutritional supplements, botanical remedies, homeopathic remedies and essential oils. Manual, movement or traction can be used to manipulate the body. There are spiritual healing modalities such as prayer and faith healing within energy healing.

Many CAM therapies treat symptoms, but not the cause. Some chronic diseases can be helped by CAM. If used in the right way, CAM can supplement conventional treatment options.

There are many reasons that people use CAM.

To improve their overall well being.
To manage a special condition.
To decrease pain or discomfort.
To prevent illness.
To promote wellness.
To address a personal belief.

Because it gives them more control than traditional medicine, some people choose CAM. Some people believe that CAM has less side effects. Some choose CAM because they don’t have to take prescription medication. Some prefer not taking prescription medications if at all possible. Others seek out CAM after having bad experiences with traditional medicine.

Some people who use CAM say they want to be sure about what they are doing before trying something new. Many CAM users have questions about safety and effectiveness. Others rely upon word-of-mouth referrals from family and friends.

Although CAM may be seen as a negative thing in society, most people who use it report positive feelings. People who use CAM are more happy and healthier than those who do not. This is true regardless age, gender and race.

Nearly all Americans use some kind of complementary and/or alternative medicine. 95% of adults have used CAM at some point in their lives. According to the National Center for Complementary and Integrative Health (NCCIH), approximately 40 million visits were made to CAM providers in 2010 alone.

The NCCIH estimates 10 percent of the U.S. populace uses chiropractors.

The American Medical Association reiterated its support for integrative medical care in 2013. It acknowledged that integrative medicine should be integrated into the clinical practice of physicians to best meet the needs and expectations of patients.

The Institute of Medicine published a landmark 2007 report called “Relating Constraints” that concluded that there was no evidence to support the claim that any particular CAM intervention can prevent, treat, cure, or cure cancer.

Despite this conclusion, CAM continues to grow in popularity. The 2008 number of CAM practitioners increased 8 percent compared with 2007.

A recent study found that almost half of the respondents reported using CAM as part of their primary healthcare regimen.

CAM therapies may include natural products and mind-body practices as well as manipulative techniques, energy healing, modalities, exercise, and dietary supplements.

Many CAM therapies are used primarily as pain relief. But, many offer additional benefits such relaxation, improved moods, better sleep, decreased stress and enhanced immunity.

Acupuncture is a treatment that can reduce chronic back pain, anxiety, depression and improve the immune system, promote weightloss, and improve menstrual symptoms.

Many CAM treatments are rooted in traditional Chinese and Ayurvedic medicine. Their roots date back thousands of years.

Traditional Chinese Medicine (TCM), for instance, originated over 5,000 years ago. This practice has been in China since antiquity.

TCM is an important component of modern health care.

TCM is used to treat a majority of Americans.

Yoga is another popular CAM treatment. Around 5000 B.C., yoga was born in India. It is now accepted all over the world.

Yoga is gaining popularity because of its many benefits, including spiritual, mental and physical.

Yoga can help ease stress, enhance flexibility and increase strength while improving cardiovascular fitness and reducing blood pressure and cholesterol levels.

Yoga has been shown to improve sleep33, even though there is not much scientific evidence. It may also be beneficial for insomnia sufferers.

Other CAM therapies like aromatherapy, homeopathy, meditation, and/or homeopathy are also becoming accepted in mainstream medicine.

One of the most used types of CAM is herbal medicine.

Herbal medicines are made up of herbs, spices flowers, seeds fruits, nuts, bark, leaves and roots.

They are often considered safer options to pharmaceutical drugs, and they are widely used by customers.

The U.S. National Center for Complementary and Integrative Health estimates that about 90 million Americans use some form of complementary/alternative medicine.

The American Cancer Society reports that 45% (or more) of those diagnosed with cancer have used alternative medicines during their illness.

According to the National Institutes of Health, 60% of cancer patients use CAM. The Centers for Disease Control and Prevention estimates that approximately 50% of cancer survivors have used CAM.

A recent study found that 51% of patients with cancer used at least one type or another of CAM.

However, only 8% of these individuals discussed this use with their physicians.

This lack of communication between conventional medical providers and CAM users represents a significant gap in healthcare delivery.
