Commercial natural language processing [NLP] products can be used to ease the “incredible burden” of paperwork faced by clinicians, Microsoft’s corporate vice president of healthcare has said.
Speaking at the Intelligent Health conference in Basel, Switzerland, Dr Peter Lee discussed how the same machine learning models used for consumer-facing translation products could be turned into ‘intelligent scribes’ capable of automatically recording medical notes.
He labelled this a “beautiful concept” that had been enabled by the “very rapidly improving fidelity” of machine learning models.
Speaking on 11 September, Dr Lee said: “There have been startling advances in natural language processing…We have been tuning these models that are commercial natural language processing and machine learning translation products for biomedical and healthcare applications.
“Much of the burnout from physicians is based on the incredible burden of clinical documentation they face.
“The kind of artificial intelligence technology that we see being used for natural language processing also hold promise of being able to reduce this burden.”
Clinical transcription tools aren’t new within healthcare – Nuance’s Dragon Dictate and UK-based Dictate IT Live are but two examples of products that are already on the market.
Yet the technology has proved somewhat of a slow burner, and major tech companies have yet to step into this space.
Dr Lee indicated that this could be about to change, saying “product commitments are now being made and in 12-18 months we’ll see a real product on the market that can listen and observe a doctors work, and use it to reduce the burden of clinical documentation”.
“In pilots, we are getting very good results and we believe we are not alone in the industry in this regard,” he added.
Dr Lee proposed that natural language processing platforms would eventually be capable of capturing additional information that could help a inform a doctor’s decision-making.
“Imagine the application of [an NLP platform] in automatically highlighting social determinates of health and capturing these transcript elements in a hands-free environment.”
Yet he acknowledged that a “fully intelligent scribe” was “still a little bit over the horizon,” but added “each application adds another brick in a wall to hold back this incredible destructive burden of documentation.”
While machine learning systems were increasing in their fidelity and availability, Dr Lee said access to data remained an obstacle to training algorithms.
He referred to what he labelled the ‘health data funnel’, in which data sharing agreements gradually drop off over time.
“We get into agreements, time passes, there are lots of legal complexities,” he said.
“Around a quarter of these turn into and actual agreement. One-tenth of these use data that can be exposed to machine learning tools. Of these, a fifth turn out to be situations where data can be exposed to data scientists.
“By the time you get there, what you started off with hundreds of thousands of opportunities ends up being just a handful.”
FHIR as ‘first-class’ datatype
Data standards pose another issue – which Dr Lee labelled “the least sexy thing in healthcare today.”
Alluding to Microsoft’s commitment to supporting open standards, he said: “All Microsoft platforms and services to speak the language of healthcare data – one standard we think very important is FHIR.
“We’ve taken the commitment of integrated FHIR into the core of our cloud platform. This is the first-class datatype in Azure.
“We’ve taken that approach because we believe our customers and partners will benefit from natively speaking the language of health data.
“We also believe health data will be the biggest data workload in the cloud – so it stands to reason FHIR should be a first-class data type.”
