AI to improve stroke care at Barking, Havering and Redbridge

#artificialintelligence

Barking, Havering and Redbridge University Hospitals NHS Trust is improving its response to stroke care with the launch of new software which uses artificial intelligence. The Brainomix software acts as a second opinion by analysing CT images of the brain and blood vessels, and automatically highlighting blocked blood vessels to indicate possible areas of damage. It also means stroke teams will be able to easily share scanned images to aid rapid diagnosis and support clinical decisions and treatments. Amanda Martin, stroke co-clinical lead at the trust, said: "At a local level, this decision support tool will help us to speed up diagnosis and therefore patient care in a simple and safe way… we are hoping that the implementation of Brainomix will support the highly specialised thrombectomy pathway, facilitating the timely transfer of those eligible for treatment to the trust." The AI technology can be used as a mobile app, meaning clinical decisions can be made swiftly and from anywhere. It will also connect the trust's stroke team with colleagues at University College London Hospitals NHS Foundation Trust and Barts Health NHS Trust and provide a 24/7 service.


Artificial intelligence predicts brain age from EEG signals recorded during sleep studies

#artificialintelligence

A study shows that a deep neural network model can accurately predict the brain age of healthy patients based on electroencephalogram data recorded during an overnight sleep study, and EEG-predicted brain age indices display unique characteristics within populations with different diseases. The study found that the model predicted age with a mean absolute error of only 4.6 years. There was a statistically significant relationship between the Absolute Brain Age Index and epilepsy and seizure disorders, stroke, elevated markers of sleep-disordered breathing (i.e., apnea-hypopnea index and arousal index), and low sleep efficiency. The study also found that patients with diabetes, depression, severe excessive daytime sleepiness, hypertension, and/or memory and concentration problems showed, on average, an elevated Brain Age Index compared with the healthy population sample. According to the authors, the results demonstrate that these health conditions are associated with deviations of one's predicted age from one's chronological age.

Deep learning with SPECT accurately predicts major adverse cardiac events

#artificialintelligence

An advanced artificial intelligence technique known as deep learning can predict major adverse cardiac events more accurately than current standard imaging protocols, according to research presented at the Society of Nuclear Medicine and Molecular Imaging 2021 Annual Meeting. Utilizing data from a registry of more than 20,000 patients, researchers developed a novel deep learning network that has the potential to provide patients with an individualized prediction of their annualized risk for adverse events such as heart attack or death. Deep learning is a subset of artificial intelligence that mimics the workings of the human brain to process data. Deep learning algorithms use multiple layers of "neurons," or non-linear processing units, to learn representations and identify latent features relevant to a specific task, making sense of multiple types of data. It can be used for tasks such as predicting cardiovascular disease and segmenting lungs, among others.

How AI Vendors Can Navigate the Health Care Industry

#artificialintelligence

The adoption of AI in health care is being driven by an exponential growth of health data, the broad availability of computational power, and foundational advances in machine learning techniques. AI has already demonstrated the potential to create value by reducing costs, expanding access, and improving quality. But in order for AI to realize its transformative potential at scale, its proponents need business models optimized to best capture that value. AI changes the rules of business and, as ever, there are some unique considerations in health care. In order to understand these, we studied AI across 15 sets of use cases. These span five domains of health care (patient engagement, care delivery, population health, R&D, and administration) and cover three types of functions (measure, decide, and execute).


New artificial intelligence prediction model may reduce hospital readmission rates

#artificialintelligence

Artificial intelligence may be a useful tool for providers to better predict patient outcomes. It was beneficial for Amod Amritphale, M.D., the director of cardiovascular research and an interventional cardiologist at USA Health, who used computer algorithms to learn more about patients who suffered a stroke. Public data showed that some of those patients were readmitted to the hospital within 30 days, even after undergoing a surgical procedure to open a narrowed carotid artery. Carotid arteries are blood vessels located on both sides of the neck that deliver blood to the head and brain. The procedure, known as carotid artery stenting (CAS), is usually performed as a preventative method or after a stroke.
