The telltale indicators of an infection appeared quickly after the affected person arrived within the emergency room. So medical doctors at China Medical University Hospital (CMUH) ordered a lab take a look at to establish the wrongdoer.
Three days later, they acquired their reply: a drug-resistant micro organism. This explicit bug had developed to outfox most antibiotics, even ones used as a final resort. It’s a infamous and doubtlessly deadly menace that haunts hospitals worldwide.
However by then the affected person was about to be discharged. That’s as a result of an AI mannequin developed by CMUH had already recognized the micro organism – in a single hour, in contrast with the 72 hours the usual lab take a look at took. Medical doctors had prescribed new medicine in consequence, and the affected person recovered.
That AI mannequin is a key pillar of CMUH’s “clever antimicrobial system,” which was deployed into scientific follow final 12 months. Since then, CMUH has seen affected person mortality fall by 25%, antibiotic prices by 30% and antibiotic use by 50%. It has helped medical doctors deal with 1000’s of sufferers very like the one who left the ER in March.

And it is only one instance of how CMUH is utilizing AI to create a brand new period of healthcare, mentioned Dr. Kai-Cheng Hsu, director of CMUH’s Synthetic Intelligence Middle for Medical Prognosis.
CMUH has developed and deployed lots of of AI algorithms, hosted on Microsoft’s Azure cloud platform, which can be used on daily basis throughout the system’s 12 hospitals. The workforce’s custom-built AI fashions are serving to medical doctors diagnose illnesses like most cancers and Parkinson’s. They’re serving to ER employees deal with stroke and coronary heart assault sufferers faster. And so they’re serving to ease the paperwork load on medical doctors and nurses.
“The most important targets of each AI software we develop are to save lots of sufferers’ lives and save medical doctors’ time,” Hsu mentioned. “Our imaginative and prescient is to be a world-class platform supplier for the AI hospital of the long run.”
Saving time, saving lives
CMUH has been laying the foundations for that AI hospital for years. In 2015, the system established a middle for large knowledge, which might guarantee affected person knowledge privateness whereas supplying coaching gasoline for AI algorithms. The AI Middle for Medical Prognosis launched two years later.

Immediately, 10 completely different AI clinics function at CMUH. A cross-disciplinary workforce of medical doctors and AI researchers meet month-to-month to debate potential new tasks and evaluation progress on current analysis. Fashions which can be efficiently validated and examined are built-in into scientific follow. Up to now, eight of its AI fashions have obtained regulatory approval from Taiwan’s Meals and Drug Administration, and eight extra have been submitted for evaluation.
All have been developed and deployed utilizing the Azure Machine Learning platform.
“Azure is on the core of our digital healthcare transformation,” mentioned Dr. Jiaxin Yu, director of CMUH’s AI Innovation Middle. “The platform lets us shortly develop new AI instruments, deploy them into the clinic and enhance the day by day follow of our physicians.”
The AI fashions are sometimes integrated into acquainted software program medical doctors use on daily basis. Some are deployed with a literal push of a button. For instance, medical doctors who order an MRI on a knee harm can click on a button marked “AI” that predicts the probability of a meniscus tear. That prompt end result can keep away from delays for a follow-up appointment and get a affected person handled faster.
Saving time usually means saving lives. That’s more and more true on the subject of the speedy identification of lethal, drug-resistant micro organism. The World Well being Group predicts that by 2050, antibiotic resistance will trigger extra deaths than most cancers.
However because the affected person with drug-resistant micro organism discovered, the usual lab methodology can take as much as three days. So CMUH developed a brand new mannequin. It mixed machine studying with a typical and far easier lab approach that identifies molecular fingerprints of various bacterial strains. Information on 1000’s of scientific samples have been used to coach the algorithm, which might precisely establish six various kinds of multi-drug resistant micro organism in a single hour, Yu mentioned.
With potential coronary heart assault sufferers, essential care may be delayed whereas ready for a specialist to evaluation an electrocardiogram (ECG), Hsu mentioned. CMUH developed an algorithm that may analyze ECGs, detect the probability of a coronary heart assault and ship a message to an on-duty specialist for affirmation.
CMUH emergency room employees have used the AI mannequin for 2 years. It has minimize in half the time between when a affected person arrives and when they’re handled, Hsu mentioned. The algorithm was so profitable they determined to companion with a medical machine producer to convey it into ambulances as an early warning system.

Hearth departments within the cities of Taichung and Nantou have used the system for almost a 12 months, Hsu mentioned. An ECG may be taken in an ambulance after which uploaded to the cloud, the place the AI mannequin might help with a prognosis and alert medical groups on the hospital to arrange for a coronary heart assault affected person. This will minimize the time between symptom onset and the beginning of therapy from two hours all the way down to 10 minutes, he mentioned.
Not all AI fashions have been as profitable, Hsu and Yu mentioned.
CMUH developed an algorithm to foretell sepsis, a severe sickness triggered by an infection. Many sufferers with sepsis present indicators of organ failure. When the AI mannequin was educated, it realized to correlate these signs with the sickness. However not all sufferers with organ failure have sepsis. Consequently, the mannequin incorrectly flagged some sufferers with organ failure as having sepsis. To resolve the issue, Yu mentioned, the workforce might prepare future fashions with extra labels to assist it distinguish circumstances the place organ failure will not be brought on by an infection.
Hsu and Yu famous that medical doctors have all the time needed to make advanced choices utilizing the information that they had. AI is there to assist help these choices by offering deeper insights into knowledge, to not make choices finest left to medical consultants.
Primarily based on CMUH’s journey, AI might help enhance the care medical doctors ship, they mentioned. That’s the reason CMUH hopes to share its AI instruments broadly utilizing the Azure platform.
“We wish to deploy our AI fashions to hospitals and clinics world wide, and it’s rather more environment friendly and cost-effective to make use of a cloud platform,” Yu mentioned. “Affected person privateness is all the time a prime concern, and a essential purpose we selected Azure is as a result of it may well guarantee the protection of delicate well being knowledge. Azure actually reduces the limitations to bringing AI into the hospital.”
