New York hospital leader: Multimodal LLM assistants will create a “paradigm shift” in patient care

Using multimodal Large Language Models (LLMs), hospital systems can create powerful virtual physician assistants to proactively track and diagnose every thing for patients, said a medical director at one in every of New York's leading hospital systems. New York Presbyterian (NYP).

Dr. Ashley Beecy, medical director of AI operations at NYP, spoke at VentureBeat's AI Impact Tour event in New York last Friday. She said her hospital system is already experimenting with generative AI in several discrete areas that provide value but pose minimal risks, corresponding to summarizing conversations from patient visits. However, she hopes that the passion for generative AI will result in a change in workflows in order that hospitals can develop powerful and all-encompassing assistants that can “change the paradigm for which I practice.”

Multimodal LLM technology can provide comprehensive, proactive care

Beecy, who also practices cardiology on the hospital, didn’t give a timeframe for when this may be possible, but mentioned that she would love to see progress over the following 12 months. She said patients are referred to her after they experience chest pain. But she said she would moderately know if her patient was going to have a heart attack before it happened. “And so we are able to use this technology and all the information that we collect concerning the patient to realize insights from a multimodal perspective – insights from things like imaging, echocardiograms and electrocardiograms that I may not have the ability to see as a human.” however the AI ​​can and does allow me to reply… before events occur.”

She said much of the technical ability to do that exists, but it surely's a matter of adjusting internal workflows and processes to make it possible, or what she called “change management.” She acknowledged that this can require a number of work and testing, and may also require the sharing of ideas across national health organizations, as major structural changes will likely be required beyond her own hospital. She sees a path where the hospital system first tackles low-risk administrative use cases for generative AI, corresponding to summarizing oral conversations from patient visits. The system will then use generative AI to approach clinical diagnostics so as, for instance, to higher detect heart diseases in individual cases. Only then can it bring all of those elements together within the more ambitious move she envisions.

“What I would love to see is a colleague – a model that may encompass all of this directly, and I can say when my next patient will likely be here and the way long that patient needs to be scheduled based on the time available.” have made up to now to see them and what’s the summary of all of the visits they’ve had since I last saw them so I can interpret that? Do you would like refills? And are you able to mechanically enter that into the electronics? “Record it for me so I can order it – all of those tasks are consolidated in order that they turn into ubiquitous in our workflow.” (See her full comments within the video below).

Beecy said that up to now NYP employees generally looked as if it would embrace generative AI and were willing to become involved in its use. NYP, which is affiliated with two medical schools at Cornell University and Columbia University, employs roughly 49,000 employees and contracted physicians.

Procedures and processes still have to be developed

Beecy said in a conversation moderated by senior AI author Sharon Goldman that the hospital is targeting AI's capabilities — things like pattern recognition, summarization, data extraction and content generation — toward crucial, highest-value applications that also pose low risk . One of her personal favorites is reducing the executive burden on physicians by recording patient visits in order that the visit conversation will be written down in a note throughout the visit, she said. Doctors have turn into what she calls “ambient scribes,” working behind a pc and only occasionally taking a look at you. They can then spend hours within the evening manually transcribing notes. “We need to change that,” she said. She said the hospital needs patients' consent to record visits as transparency is crucial. However, the outcomes can be significant because it eliminates the necessity to create content and as an alternative allows the doctor to validate and edit the content.

She said using AI for clinical diagnostic applications is tougher when put next to administrative applications corresponding to these. But one use case NYP is exploring is using electrocardiograms to find out whether you could have structural heart disease. This is when you could have problems together with your heart valves or muscles and this will likely be diagnosed through an ultrasound scan of the guts. Not everyone gets such an ultrasound, but many individuals get an electrocardiogram, a snapshot of your heart's electrical activity that also can use AI to detect heart disease. “You can screen people sooner and get them the care they need,” she said.

There are many risks, but there may be great enthusiasm for AI

Asked whether she had concerns concerning the risk of generative AI making errors in these applications, she said there was “lots to make clear” concerning the risk, but so long as the doctor reviews the summaries of visits and diagnoses, Most risks will be avoided. She said the technology is “not at 50 percent because we wouldn't use it.” It's not at 100% because it might replace all of our jobs. It’s probably 90 percent, which is why I say the provider would check it at the top.”

Another risk is relying an excessive amount of on technology, she said. LLM technology has improved a lot – Beecy pointed to ChatGPT's progress in moving from GPT 3.5 to GPT 4 – that individuals may turn into too complacent and keeping a human within the loop may lose its value, said she.

NYP is taking a conservative, measured approach to the technology, Beecy said, ensuring that two key players are aligned – those that need to adopt generative AI tools and people who will use them. Employees are concerned about how it’s going to be integrated into workflows and what it means for them, she said, but added: “I might say there may be a number of excitement… in the meanwhile we have now people who find themselves keen to try it.”

Generative AI is proving to be a democratizing force

In the past, Beecy said, technology tended to be handed right down to employees from above. But that is the primary time the technology will likely be truly democratized by giving doctors and other providers in NYP access to ChatGPT, she said. “They can use AI, communicate with it, and really develop use cases that they find worthwhile.” Having use cases come from the top users themselves, moderately than from the highest, helps with engagement and alter management, she said.

She said the hospital is attempting to survey patient groups to grasp how transparent NYP must be with the technology. Questions include whether a patient desires to know each time the technology is used. Beecy said these are complicated questions and require a multidisciplinary team, maybe even including sociologists and bioethicists.

Sarah Bird, global head of responsible AI engineering at Microsoft, spoke in a session following Beecys, in a conversation moderated by Sharon Goldman and me. We asked her whether Beecy's vision of an ambitious, all-encompassing physician assistant can be achievable within the foreseeable future, given the state of Microsoft's AI technology. (Microsoft works closely with OpenAI to bring generative AI to enterprises.)

Bird suggested that technology can provide the constructing blocks vital for such an assistant, corresponding to breaking down a process into specific tasks and grounding the technology with access to reliable information. However, she said one problem with generative AI summaries is that the technology can add information that might not be accurate or miss information. Omitting a symptom from a health care provider's visit summary can completely change the meaning of the diagnosis, she said. “We have been experimenting with techniques to offer the model a deeper understanding of medical information in order that it might probably actually summarize effectively.”
