Searching for Medical Information Through Speech Recognition

This is for mobile busy doctors. May I intervene into your busy day by announcing that Nuance Healthcare, Inc, a software company that develops Dragon Naturally Speaking solutions for doctors in small practices and for small hospitals, has a new product.

It goes by the name of Dragon Medical Mobile Search. It allows you to search the Web using your own voice. You can search for drug interactions, new medications,ICD-9 codes, and news about a particular condition.

I wrote about speech recognition as a supplement to EHRs in a previous blog, which I reproduce here,

For Fans of Electronic Health Records

Nuance, a very slight difference in meaning, feeling, or tone.

Dictionary definition of Nuance

I have never been a big fan of electronic health records. EHRs lack nuance. With EHRs physicians can’t express themselves in plain English, just in data bytes. EHRs too often generate unreadable numeric gibberish. They fail to pass the test of useful narrative information.

So much for my electronic angst.

As always, I may be wrong. Now, there may be a technological breakthrough. In the March 14 NEJM, Drs. Gorden Schiff and David Bates of Harvard write “Can Electronic Clinical Documents Help Prevent Diagnostic Errors?”

Their answer is "Yes". Improved speech recognition technology now makes it possible for physicians to clearly describe and communicate the patient’s story without typing or handwriting, while a the same time, as a bonus, decreasing diagnostic errors.

The two authors then list other benefits of EHRs speech recognition technology.

• Gain access to information in narrative context

• Record and share clinical assessments in plain language

• Maintain a dynamic and current patient history

• Maintain problem lists

• Track medications

• Track tests

• Coordinate and control care

• Enable follow-up

• Provide follow-up to clinicians upstream

• Offer second opinions

• Increase efficiencies

The biggest benefit of computerized speech, from my perspective, is that speech recognition allows physicians to tell the patient’s story, past and current, without scanning reams of data. Perhaps I am impressed with Nuance Healthcare software because I believe in old-fashioned story telling and the power of narrative.

In any event, here’s how Nuance Healthcare, speech recognition software developers, and a disruptive player in the HIT space, interpret the work of Drs. Schiff and Bates.

“Dr. Schiff and Dr. Bates struck a particularly relevant chord with their paper on the impact that electronic clinical documentation can have on preventing diagnostic errors,” said John Shagoury, executive vice president and general manager, Nuance Healthcare. “More than 150,000 physicians use our speech recognition technology to document patient encounters without having to type or handwrite. The majority of these doctors will tell you that speaking their medical notes, is not only faster, but it allows doctors to include more information on their patients. It’s wonderful to see the free-text narrative, along side EHR point-and-click templates, being recognized as highly important and valuable to improve patient care, as well as to improve physician and patient interactions. One customer of ours, The Fallon Clinic, saw the quality of medical notes improve by 26 percent when they were created with speech recognition.”

I close with this verse, which tells the story more succinctly than prose

With EHRs, there really nothing like human speech,
To capture nuances beyond ordinary data’s reach.
There’s more to telling a patient’s story beyond data,
Which unwittinglymay produce unexpected errata.
So now of EHRs I can speak and preach.
