May I Speak to the Doctor's Computer?

By Kim Bellard, June 25, 2014

There's a new provocative study in Computers in Human Behavior that suggests we may be more likely to tell the truth about personal matters, such as health problems or medical history, when talking to a virtual human instead of to an actual human.  I'm not sure if these findings threaten to set back the patient-physician relationship 10,000 years, or promise to advance it fifty years.

The article -- It's Only a Computer, by Lucas, Gratch, King, and Morency -- tested participants' willingness to disclose information to a "virtual human" on a computer screen.  When the participants believed the virtual human was fully automated instead of being controlled by a human, they reported lower fear of self-disclosure, were less likely to shade the truth in order to create a good impression ("impression management"), and were rated as being more willing to disclose information.  The key to the behavior was their belief that no human was involved, whether or not a human was actually acting behind the scenes.

The virtual human idea is not pie-in-the-sky, good only for research studies.  Versions of it are already being tested, such as by Sense.ly, whose digital health avatar was profiled by MIT Technology Review a year ago.  It captures patient information via an avatar, which can respond to patient statements or data and can even answer questions.  

Clearly, we're entering a new world.

The kind of artificial intelligence that might power these avatars/virtual humans can also be used to assist physicians instead of competing with them.  IBM, of course, has been touting Watson in health care for several years now.  As Wired recently reported, there are a number of AI efforts out there to assist physicians. 

Wired also notes that companies are trying to keep their products viewed as offering recommendations instead of making decisions, which would push them over into FDA approval and regulation.  We probably will get there, but that step will be a big gulp.

Some experts believe people will improve their health behaviors -- e.g., get more exercise or lose more weight -- if they know they are being monitored.  Others fear people will end up forgetting about their trackers and will slide back to their previous behaviors. 

The plethora of tracking devices poses issues not only with the sheer volume of data generated, but also with integrating the disparate data from multiple operating systems into a unified record. 

The idea that health information is only collected at a medical office or lab, and that patients should wait to act on it until a human can talk to them, is simply no longer viable.  The data are increasingly going to be available 24/7, and when it means something important there have to be mechanisms to act upon it in real-time.   Maybe that is through alerts to physicians, who then initiate contact with patients, or maybe the wearable ecosystem can trigger its own alerts and advise the user what is going on using avatars and other automated mechanisms.

A recent op-ed by Dominic Basulto in The Washington Post stated that "Google and Apple want to be your doctor, and that's a good thing."  Mr. Basulto concluded:

Companies like Apple and Google can help to break down the notion that health has to be something offered by a monolithic company with a confusing set of rules and terms. It might just be the case that mobile health care facilitated by wearable tech will turn out to be better than traditional doctors.

I think it is a stretch to say that mobile health will be "better" than traditional doctors, but I think these and other technological options can certainly radically change when, why and where people need to see physicians or other health care professionals.  And that's good.
