AI will be critical for the future of rural health care in Canada, experts say

There won't be androids rushing through hospitals or drones hovering to triage patients just yet, but artificial intelligence is starting to makethe rounds when it comes in health care in Canada.

As the technology evolves and becomes more mainstream, while staying firmly behind the computer monitor, experts say rural Canadians may have the most to gain.

Dr. Alex Wong is the Canada Research Chair for Artificial Intelligence.

While he says the country at large will benefit from AI makinghealth care work more efficient, rural Canadians will see "an even greater impact" as the science helps doctors, nurses and specialists in regions with fewer staff.

"Resources are even more limited that's where AI can really come in place," Wong said.

When you see a doctor on a computer, they're looking at images, records and data. Now you have this additional AI that provides additional insights and information. Dr. Alex Wong

"With their expertise having seen this big worldview of thousands, to hundreds of thousands, to millions of different patients, it's able to [take] that knowledge and bring it to rural areas to help improve diagnosis and improve treatment."

Wong and others say artificial intelligence will help health-care providers with things like:

• Organizingthe mountain of paperwork that human staff have to handle currently.
• Takingstress off the system by making patient records and histories much easier to access.
• Assisting with staff scheduling, with a focus on anticipating whenshortages will crop up.
• ExaminingX-rays, MRI scans, CT scans and otherdigital images that doctors and specialists now study, andproviding extremely accurate diagnoses.

Some of those tasks are already being carried out by AI health systems inToronto and Montreal. On a panel for The National, Dr. Muhammad Mamdani, vice-president of data science and advanced analytics at Unity Health Toronto, said some tasks that "normally take two to four hours every day by a few people, it's reduced to under 15 minutes."

Wong said doctors of the near future will use AI as a "clinical vision support system" that will give staff more insight into illnesswhen they interact with patients.

"When you see a doctor on a computer, they're looking at images, records and data. Now you have this additional AI that provides additional insights and information," Wong said."Essentially you treat it as a second recommendation."

AI emerging as vital tool inrural Australia

Similar experiments arebeing done in Australia.

Like Canada, it's a country that hasa large landmass with many rural and remote areas, and fewer staff and specialists in those areas.

The countryhas its own unique challenges. Care units like theRoyal Flying Doctors Serviceare regularly deployed to provide care to the most remote communities, but what AI can do in rural areas is starting to becomemore widely understood.

Dr. Stefan Harreris chief innovation officer for theDigital Health Cooperative Research Centre. He said AI will cut down significantly on the paperwork that preoccupieshealth care workers countrywide.

"The degree of documentation and reporting that clinicians have to undergo everyday is overwhelming, right, so they spend way more than half their time on writing summaries, producing discharge reportscreating medical reports," he said in an interview from Melbourne.

We're in a very, very exciting time right now, where the appetite to use AI is unprecedented. Dr. Stefan Harrer

"That is a massive inefficiency, and eats up a lot of the potential and energy that clinicians could bring to other parts of their roles, interacting with patients, actually treating patients."

The federal Department of Science says it is "committed to ensuring all Australians share the benefits of artificial intelligence," calling it acritical technology of national interestthat could help solve health challenges.

On the ground, a company named DrumBeat AI usesimages of patients' inner earstoidentify ear disease in Indigenous children inremote parts of Australia. It has made local and national news for how it's helping people.

"To help healthcare workers with limited experience to instantly triage ear disease and detect hearing loss, our team has developed and published the first artificial intelligence (AI) algorithm for Indigenous children," saidDr. Al-Rahim Habib, project lead with DrumBeatin an email.

"The overarching purpose of DrumBeat.ai is to enhance the capacity of frontline healthcare workers in rural and remote areas to quickly identify ear disease, inform judgment, and improve clinical decision-making."

Harrer said what DrumBeat and others in the field are doing is life changing for patients, and crucial to the future of health care in rural areas.

"There aren't always experts on the ground in these rural communities to perform these checks, do this monitoring and get the diagnosis right," Harrer said.

"That's an application where an AI-driven, cloud-based you could call it a tele-health solution brings immediate value and impact to improving the health of rural communities and Indigenous communities."

'AI does not, ever, replace humans'

The technology isn't without controversy, however. In Australia, as in Canada, there are concerns about cybersecurity, safety, regulation and how the use of AI could affect jobs.

Both Harrer and Wong say AI systems will need to have regulation and oversight.

"They all help the human, right? They all assist humans in empowering them to do it better, do it faster and have more impact with what they do," Harrer said.

"AI does not, ever, replace humans. That is not where this is going ... if AI in health care has to be described in one word, it's 'assistance.' That's what it's there for. Not replacement."

Wong said the goalis to help clinicians literally see and do more,and have more datain their hands quickly.

"Doctors are indispensable, nurses are indispensable, health-care workers are indispensable," Wong said. "If we can help them better, than they can see more patients, they can have greater consistency in their diagnoses and patient treatment."

Internet a possible stumbling block

Part of the issue Canada faces in using AI is that many rural communities still don't have stable access to high-speed internet. Infrastructureas a wholeis still experiencing a "persistent digital divide,"Auditor General Karen Hogan said earlier this year regarding rural connections.

Ottawa has set a goalof connecting 98 per cent of Canadians to high-speed internet by 2026, with universal access by 2030.

Health Minister Mark Holland said last week ashealth ministers met in Charlottetown that digital record sharing in health-care will be a huge priority for federal, provincial and territorial governments going forward.

That would make it easier to roll out AI health care technology at a time when countries similar to Canadaare thinking about the very same thing.

"Bringing health care to these communities is a key imperative of the Australian health-care system," Harrer said.

"We're in a very, very exciting time right now, where the appetite to use AI is unprecedented. There is absolutely a reason to be excited, and positiveand inspired by where this leads Health care and medicine is where the stakes are highest."
