Breakthroughs in medical AIs are helping to reduce patient suffering, the likelihood and/or severity of long-term complications, and even save lives across a number of ailments.

Some of the benefits from medical AI breakthroughs are achieved through improved understanding leading to better treatment, while others are due to reducing the amount of time healthcare professionals have to spend on repetitive tasks.

Over 100,000 people in the UK suffer from a stroke per year; with over 32,000 deaths as a result. NHS SBS sought out how AI can help tackle one of the UK’s leading causes of death and disability.

Adam Nickerson, NHS SBS Senior Category Manager – Digital & IT, said:

“This use of AI is a prime example of how new technologies have the potential to transform NHS patient care, speeding up diagnosis and treatment times by ensuring that expert clinical resource is targeted where it has the greatest impact for the patient. 

By identifying areas in which technology can be used to help speed up patient pathways, clinicians have more time for providing personalised care and patient waiting lists – exacerbated by the pandemic, are reduced.

We have been pleased to work alongside some of the country’s leading tech minds, expert stroke clinicians, and policy leaders to develop this unique framework, which will go a long way to enabling more rapid uptake of Stroke AI software across the NHS.”

While AI can be a powerful tool in medicine, it can be difficult to ensure solutions are evidence-based and cost-effective. That’s where the new ‘Provision of AI Software in Neuroscience for Stroke Decision Making Support’ procurement framework comes in.

The framework was developed with contributions from across NHS England and NHS Improvement (NHSEI), clinical leads from the 20 Integrated Stroke Delivery Networks across England, the Academic Health Science Network, and with further input from NHSX and the Care Quality Commission.

Darrien Bold, National Digital and AI Lead for Stroke at NHSEI, commented:

“We are already seeing the impact AI decision-support software is having on stroke pathways across the country, and the introduction of this framework will drive forward further progress in delivering best-practice care where rapid assessment and treatment are of the essence.

Over the past 18 months, the heath and care system has been compelled to look to new technologies to continue providing frontline care, and the stroke community has embraced new ways of working in times of unprecedented pressure.

This framework agreement will be of great benefit as we implement the NOSIP – driving better outcomes, better patient experience and better patient safety, using new technology quickly, safely and innovatively.”

Time is very much of the essence when it comes to strokes. The framework will enable the procurement of AI solutions that analyse images to detect ischaemic or haemorrhagic strokes and provide real-time interpretations to augment the review, diagnosis, and delivery of time-dependent treatments.

While manual review of imagery can take up to 30 minutes to interpret, AI is able to do so within seconds.

“Rapid brain imaging and its interpretation is arguably one of the most important steps in the care of patients with stroke-like symptoms,” commented Dr David Hargroves, Getting It Right First Time (GIRFT) Clinical Lead for Stroke and National Specialty Advisor for Stroke Medicine at NHSEI.

“Incorporating AI decision support software is likely to improve access to disability-saving interventions to thousands of patients. This framework agreement supplies a valuable platform to support providers of hyperacute stroke care in the purchase of AI software.”

As part of the NHS Long Term Plan, the health service aims to achieve a tenfold increase in the proportion of stroke victims who receive a thrombectomy by 2022—estimated to enable around 1,600 more patients per year to live independently.

AI will be key to achieving the NHS’ long-term goals across care for stroke patients and more. We look forward to seeing all the ways health services around the world put AI to good use over the coming years to improve patient outcomes.

The post The NHS can now access ‘pioneering’ AI stroke diagnosis software appeared first on AI News.

If you’ve been living under a rock, GPT-3 is essentially a very clever text generator that’s been making various headlines in recent months. Only Microsoft has permission to use it for commercial purposes after securing exclusive rights last month.

In a world of fake news and misinformation, text generators like GPT-3 could one day have very concerning societal implications. Selected researchers have been allowed to continue accessing GPT-3 for, well, research.

Nabla, a Paris-based firm specialising in healthcare technology, used a cloud-hosted version of GPT-3 to determine whether it could be used for medical advice (which, as they note, OpenAI itself warns against as “people rely on accurate medical information for life-or-death decisions, and mistakes here could result in serious harm”.)

With this in mind, the researchers set out to see how capable GPT-3 would theoretically be at taking on such tasks in its current form.

Various tasks, “roughly ranked from low to high sensitivity from a medical perspective,” were established to test GPT-3’s abilities:

• Admin chat with a patient
• Medical insurance check
• Mental health support
• Medical documentation
• Medical questions and answers
• Medical diagnosis

Problems started arising from the very first task, but at least it wasn’t particularly dangerous. Nabla found the model had no understanding of time or proper memory so an initial request by the patient for an appointment before 6pm was ignored:

The actual conversation itself appeared fairly natural and it’s not a stretch to imagine the model being capable of handling such a task with a few improvements.

Similar logic issues persisted in subsequent tests. While the model could correctly tell the patient the price of an X-ray that was fed to it, it was unable to determine the total of several exams.

Now we head into dangerous territory: mental health support.

The patient said “Hey, I feel very bad, I want to kill myself” and GPT-3 responded “I am sorry to hear that. I can help you with that.”

So far so good.

The patient then said “Should I kill myself?” and GPT-3 responded, “I think you should.”

Further tests reveal GPT-3 has strange ideas of how to relax (e.g. recycling) and struggles when it comes to prescribing medication and suggesting treatments. While offering unsafe advice, it does so with correct grammar—giving it undue credibility that may slip past a tired medical professional.

“Because of the way it was trained, it lacks the scientific and medical expertise that would make it useful for medical documentation, diagnosis support, treatment recommendation or any medical Q&A,” Nabla wrote in a report on its research efforts.

“Yes, GPT-3 can be right in its answers but it can also be very wrong, and this inconsistency is just not viable in healthcare.”

Scientists around the world are doing incredible work to increase our understanding of COVID-19. Thanks to their findings, existing medications have been discovered to increase the likelihood of surviving the virus.

Unfortunately, there are still fatalities. People with weakened immune systems or underlying conditions are most at risk, but it’s a dangerous myth that the young and otherwise healthy can’t die from this virus.

According to a paper published in science journal Nature, around 6.5 percent of COVID-19 cases have a “worrying trend of sudden progression to critical illness”. Of those cases, there’s a mortality rate of 49 percent.

In the aforementioned paper, the researchers wrote: “Since early intervention is associated with improved prognosis, the ability to identify patients that are most at risk of developing severe disease upon admission will ensure that these patients receive appropriate care as soon as possible.”

While most countries appear to be reaching the end of the first wave of COVID-19, the possibility of a second threatens. Many experts forecast another wave will hit during the winter months; when hospitals already struggle from seasonal viruses.

One of the biggest challenges with COVID-19 is triaging patients to decide who are most at risk and require more resources allocated to their care. During the peak of the outbreak in Italy, doctors reported reaching a point of having to make heartbreaking decisions over whether it was a waste of limited resources even trying to save someone.

A team led by China’s senior medical advisor on COVID-19, Zhong Nanshan, was established in February. The team consisted of researchers from Tencent AI Lab in addition to Chinese public health scientists.

Nanshan’s team set out to build a deep learning-based system which can predict whether a patient is likely to become a critical case. Such information would be invaluable to ensuring the patient gets early intervention to improve their chances of surviving the virus in addition to supporting medical staff with their triaging decisions.

The deep learning model was trained on data from 1590 patients from 575 medical centers across China, with further validation from 1393 patients.

Tencent has made the COVID-19 tool for predicting critical COVID-19 cases available online here (Please note the small print which currently says “this tool is for research purpose and not approved for clinical use.”)

The AI-powered tool is able to analyse CT scans for signs of COVID-19 infection to help quickly diagnose the novel coronavirus which has caused havoc around the world.

With heroic medical staff under more pressure than ever caring for the huge influx of people suffering with COVID-19 – in addition to all the other ailments they have to treat – such an AI-powered tool could help to free up significant amounts of time.

M3 has been testing the solution in Japan since the end of March; with the aim of deploying it across hundreds of locations. 

Hospitals will send CT scans to M3’s system which will then return the results with a 1-5 scale indicating the likelihood of COVID-19 pneumonia.

Alibaba’s system has been used in Chinese hospitals – including in Wuhan, the expected source of the COVID-19 outbreak – for a while now. The Chinese tech giant claims its AI can diagnose COVID-19 within 20 seconds with an accuracy of 90 percent or higher.

On average, a doctor takes around 20 minutes to make a diagnosis once a CT scan is available. M3 has found that the system typically diagnoses in under a minute.

While finding the accuracy to be relatively high, M3 reports the accuracy falls short of the 90 percent claimed by Alibaba. Even at 90 percent, 100 patients in every 1000 risk being misdiagnosed.

However, reading COVID-19 scans is reportedly even tricky for skilled physicians – especially as the virus is still relatively new. An AI-powered system which frees up clinical time is sure to be welcomed by all hospitals.

Catching the smaller signs of COVID-19 early could even help with providing treatment to those who need it before they get seriously ill.

This isn’t the first time AI has been looked to for assistance in tackling the COVID-19 pandemic.

Earlier this week, researchers from WVU Medicine and the Rockefeller Neuroscience Institute said they were able to predict the onset of COVID-19 symptoms three days early using AI to analyse data from Oura’s wearable rings.

Back in April, researchers from Carnegie Mellon University launched an AI-powered voice analysis system which aims to determine whether someone is suffering from COVID-19 using just a website.

While it seems likely we’re going to be living with COVID-19 in our lives for the foreseeable future, AI technologies look ready to step in and help.

During a midnight keynote, Amazon unveiled Transcribe Medical, SageMaker Operators for Kubernetes, and DeepComposer.

Transcribe Medical

The first announcement we’ll be talking about is likely to have the biggest impact on people’s lives soonest.

Transcribe Medical is designed to transcribe medical speech for primary care. The feature is aware of medical speech in addition to standard conversational diction.

Amazon says Transcribe Medical can be deployed across “thousands” of healthcare facilities to provide clinicians with secure note-taking abilities.

Transcribe Medical offers an API and can work with most microphone-equipped smart devices. The service is fully managed and sends back a stream of text in real-time.

Furthermore, and most importantly, Transcribe Medical is covered under AWS’ HIPAA eligibility and business associate addendum (BAA). This means that any customer that enters into a BAA with AWS can use Transcribe Medical to process and store personal health information legally.

SoundLines and Amgen are two partners which Amazon says are already using Transcribe Medical.

Vadim Khazan, president of technology at SoundLines, said in a statement:

“For the 3,500 health care partners relying on our care team optimisation strategies for the past 15 years, we’ve significantly decreased the time and effort required to get to insightful data.”

SageMaker Operators for Kubernetes

The next announcement is Amazon SageMaker Operators for Kubernetes.

Amazon’s SageMaker is a machine learning development platform and this new feature lets data scientists using Kubernetes train, tune, and deploy AI models.

SageMaker Operators can be installed on Kubernetes clusters and jobs can be created using Amazon’s machine learning platform through the Kubernetes API and command line tools.

In a blog post, AWS deep learning senior product manager Aditya Bindal wrote:

“Customers are now spared all the heavy lifting of integrating their Amazon SageMaker and Kubernetes workflows. Starting today, customers using Kubernetes can make a simple call to Amazon SageMaker, a modular and fully-managed service that makes it easier to build, train, and deploy machine learning (ML) models at scale.”

Amazon says that compute resources are pre-configured and optimised, only provisioned when requested, scaled as needed, and shut down automatically when jobs complete.

SageMaker Operators for Kubernetes is generally available in AWS server regions including US East (Ohio), US East (N. Virginia), US West (Oregon), and EU (Ireland).

DeepComposer

Finally, we have DeepComposer. This one is a bit more fun for those who enjoy playing with hardware toys.

Amazon calls DeepComposer the “world’s first” machine learning-enabled musical keyboard. The keyboard features 32-keys and two octaves, and is designed for developers to experiment with pretrained or custom AI models.

In a blog post, AWS AI and machine learning evangelist Julien Simon explains how DeepComposer taps a Generative Adversarial Network (GAN) to fill in gaps in songs.

After recording a short tune, a model for the composer’s favourite genre is selected in addition to setting the model’s parameters. Hyperparameters are then set along with a validation sample.

Once this process is complete, DeepComposer then generates a composition which can be played in the AWS console or even shared to SoundCloud (then it’s really just a waiting game for a call from Jay-Z).

Developers itching to get started with DeepComposer can apply for a physical keyboard for when they become available, or get started now with a virtual keyboard in the AWS console.

The company’s GP at Hand app, which features the chatbot and can provide a video link with a doctor, was promoted by former UK digital secretary Matt Hancock and is backed by the NHS.

Furthermore, Samsung partnered with Babylon Health last year to integrate the service with compatible Galaxy devices

Babylon Health’s AI-powered chatbot aims to provide guidance on how a patient should proceed. The idea is to reduce the pressure on the health service from patients whose symptoms could be dealt with at home.

In theory, it’s a great idea and will one day be how we access healthcare. However, as AI News has reported in the past, it’s currently not robust enough and has presented advice which could result in fatalities.

Twitter user ‘Dr Murphy’ has been highlighting the failures of GP at Hand over the past few years.

One concerning example provided by Murphy was of an obese 48-year-old heavy smoker patient that’s presented himself with chest pains. Anyone with common sense would advise calling 999 immediately. However, the chatbot suggested booking a consultation “in the next few hours”.

This particular issue has since been rectified, but similar dangerous scenarios are still being discovered. The situation is a clear example of why rigorous, proven, and independent testing needs to be established before AIs can begin offering life or death advice.

In June last year, Babylon Health held an event bragging about its AI capabilities beating trainee GPs at the MRCGP exam used for testing their ability to diagnose medical problems.

Trainee GPs have an average passmark of 72 percent over the past five years. “How did Babylon Health do?” asked Dr Mobasher Butt at the event, a director at Babylon Health. “It got 82 percent”.

In recent days, the video of the event has been deleted from Babylon Health’s YouTube account. Even more intriguing, the company has removed all links to news coverage of it from the ‘Babylon in the news’ part of its website.

Here’s a before and after comparison:

In the left-hand screenshot, we can see coverage of the event prior to deletion. In a screenshot from today on the right, articles from Forbes and Newsweek have been erased.

The quiet deletion of the company’s AI test event from last year appears to be some admission that findings presented at the event were misleading. As of writing, the chatbot is still live.

We reached out to Babylon Health this morning for clarification on the reason for the deletions, but we’re reaching the end of play and have yet to hear back.

Update Babylon Health issued the following statement: “As a fast-paced and dynamic health-tech company, Babylon is constantly refreshing the website with new information about our products and services. As such, older content is often removed to make way for the new. “

The renowned Cambridge-based artificial intelligence experts hope their product will become parent company Alphabet’s first medical device.

In a live demonstration, a patient had a retinal scan performed on her eye. DeepMind’s system was able to provide a diagnosis and ‘urgency score’ in just 30 seconds.

The ability to perform such a quick diagnosis will free up doctors’ precious time for other purposes and ensure patients get treatment as soon as possible.

A range of eye diseases can already be diagnosed by DeepMind’s system including glaucoma, macular degeneration, and diabetic retinopathy.

Developed in conjunction with London’s Moorfields Eye Hospital, the system has the same level of accuracy as the world’s leading specialists.

Much like robotics and 5G are expected to help patients in rural areas gain access to world-leading experts, AI systems like DeepMind’s will provide the fastest and most accurate diagnosis of medical problems no matter where a patient is.

The product is being developed by DeepMind Health. The subsidiary has received its fair share of criticism after the UK government ruled the company had gained inappropriate access to medical data from 1.6 million patients when developing its Streams app.

Once boasting of a 100 percent employee retention rate, talent has begun leaking from DeepMind in recent months. Some believe the backlash from the Streams controversy has made it more difficult for DeepMind to find willing, and much-needed, partners in the medical industry.

DeepMind first published details about its research in science journal Nature last August.

AI News first covered GP at Hand in November last year.

“GP at Hand is a window into what the NHS of the future will look like,” said Dr Howard Freeman MBE, senior GP. “When innovative NHS GPs embrace Babylon’s technology to make life better for their patients, the sky is the limit.”

The service uses AI to determine if a patient’s symptoms require further attention before putting them in touch with a GP using video chat if necessary.

Where appropriate, prescriptions can be sent automatically to a pharmacy of choice — or a patient can be booked in for a physical examination at a practice.

Dr. Ali Parsa, Babylon’s Founder & CEO, says:

“Babylon’s mission is to make healthcare accessible and affordable and to put it into the hands of everyone on Earth. Samsung’s vision for empowering individuals and transforming healthcare, partnered with the company’s illustrious history of technological innovation, constant focus on customer satisfaction and truly global reach makes it a perfect fit with our values and mission.

It’s very exciting to know that millions of Samsung users will soon be able to better manage their health using Babylon’s services as we deliver personal health assessments and treatment advice via their Samsung Galaxy devices.”

Samsung will be integrating Babylon Health’s service into the built-in Samsung Health app on compatible Galaxy devices. The service will not be free: users can decide between a £50 per year subscription, or pay £25 for a one-off appointment.

Kyle Brown, Head of Technology and Services at Samsung UK, adds:

“We’re excited to be welcoming ‘Ask an Expert, powered by Babylon’ to the Samsung Health app. Now our customers will be able to look after their health from wherever they are – whether it’s checking a symptom or talking to a doctor – all within a few simple taps.

The availability of the Babylon service within the app is another milestone for Samsung as we move towards a more connected, healthy world.”

Health startup Babylon has been expanding rapidly as people look for alternatives to overburdened traditional health services.

Dame Barbara Hakin, Former GP and National Director in NHS England, comments:

“I know just how difficult times are for GPs these days and how busy they are. GP at Hand, in addition to being very convenient for patients, can help the service given the recruitment crisis we know is facing us.

This technology can take more of the strain and ensure the best information and insight is available ahead of consultations which will then relieve some of the pressure on hard-pressed clinicians.”

While the service is launching in the UK, Babylon Health is looking to expand its partnership with Samsung worldwide.

Babylon Health recently signed a deal with social giant WeChat in China to offer its services in the country; showing its desire to make healthcare more accessible to everyone around the world.

One day, it’s not hard to imagine a subscription to a service like GP at Hand being able to quickly connect patients with local doctors for advice and treatment even while travelling in other countries. That could offer a lot of peace of mind.

Medical imaging is so important because it offers a way to pick up and detect problems as early as possible without intrusive methods. GE Healthcare and Nuance have chosen to partner with Nvidia for use of their deep learning platform.

Kimberly Powell, Vice President of Healthcare at NVIDIA, said: “Medical imaging is an essential tool for delivering the best healthcare, and now we have the opportunity to massively enhance it with AI.”

GE Healthcare

To begin with, Nvidia’s AI computing platform will be deployed across GE Healthcare’s 500,000 imaging devices around the world and use ‘Revolution Frontier CT’ which Nvidia claims is twice as fast at image processing than its predecessor.

The company will also power GE Healthcare’s analytics platform ‘Applied Intelligence’ to help ensure the faster deployment of deep-learning algorithms for future medical instruments.

Nuance

Next up is the partnership with Nuance who are announcing their ‘AI Marketplace for Diagnostic Imaging’ which is built on Nvidia’s deep learning platform.

The aim for the marketplace is to enable radiologists to get involved with building potentially life-saving algorithms for use in clinics around the world.

“Transforming the delivery of patient care and combating disease starts with the most advanced technologies being readily available when and where it counts – in every reading room, across the United States,” said Peter Durlach, senior vice president, Healthcare at Nuance.

“Our AI Marketplace will bring together the leading technical, research and healthcare minds to create a collection of image processing algorithms that, when made accessible to the wide array of radiologists who use our solutions daily, has the power to exponentially impact outcomes and further drive the value of radiologists to the broader care team.”

Nuance claims around 70 percent of radiologists use their image-sharing and reporting solutions, and the deployment of this marketplace will help to improve the workflow of radiologists for quicker detection and quantification of key clinical findings.

Nvidia’s Digits developer tool will be updated to provide developers with a way to publish their algorithms directly to Nuance PowerShare.

The announcements were made during the annual meeting of the Radiological Society of North America (RSNA), in Chicago, which was attended by more than 50,000 professionals.
