Doctors, like all other humans, are limited by a myriad of factors. They’re proud, can’t recall every single disease discovered, and most frighteningly, often misdiagnose some of the more complicated and uncommon diseases.
IBM Watson looks to bridge this gap between diagnosis and disaster. While “enrolled” at Columbia’s Medical School in 2011, IBM scientists began uploading millions of peer-reviewed medical journals to its database.
This uploading process has been active for over five years now. No human doctor could ever hope to accumulate this much medical knowledge in one lifetime.
At the end of the day, we are only human, and some knowledge and pattern recognition falls through the cracks. Watson has the unique advantage of being able to sort through and analyze an ever-growing database of medical information.
Watson is a VERY Fast Reader
In cases where the correct diagnosis is crucial to treatment (and survival), time is of the essence. Instead of “guessing and checking,” Watson runs millions of calculations and searches its immense databases to vastly reduce the risk of misdiagnosis.
20 million papers in 10 minutes. Clearly, Watson is a great skim-reader.
While doctors have to rely on a mixture of their prior experiences, training, and gut intuition, Watson takes out these “human” factors, looking strictly at the facts. In doing so, Watson is able to consistently give the correct diagnosis that many doctors may overlook.
Also, Watson scanning its database is far less invasive than the myriad of tests doctors often run on their patients.
How Wrong Can Doctors Be?
A lot. An unnerving amount, actually.
According to one report by CBS News, an astounding 12 million Americans are misdiagnosed each year. That’s 1 in 20 adult patients, with about half of those misdiagnoses resulting in serious harm.
In case you’re struggling with the math, that’s six million Americans each year seriously harmed by misdiagnoses.
That means six million people are being treated for the wrong disease. Six million people aren’t getting the correct treatment they need; in fact, they’re being treated for something totally different.
Humans Have Emotions
The above figures are not meant to say that doctors are careless. But–and here’s where Watson can make a huge difference–humans have emotions. Computers don’t.
Once a doctor diagnoses a patient, he/she is emotionally invested in two ways.
The doctor wants to treat and save the patient, another human.
No doctor wants to be associated with the wrong diagnosis after years of training and medical school.
What doctor wants to swallow the inconvenient truth that they’ve just killed a treatable patient through misdiagnosis. And where do we go from here…
Do we riot and fire all doctors, instead installing computers in every hospital room?
Where Do We Go From Here?
There are things that doctors do much better than a computer can, such as bedside manner. Right now, IBM Watson is nothing more than a tool for doctors to use.
By spending less time on diagnosis, doctors can focus and prioritize other things, such as seeing more patients or following up more frequently.
Going forward, Watson will not only act as a bridge between doctor and diagnoses, but between patients and the medical community.
Watson’s computing capabilities make it a great diagnostic tool that can routinely be updated with new information. With its deep learning abilities, Watson’s going to be able to pick out the nuances of future diseases with more regularity and precision.
While Watson is an amazing resource, that’s all it is. A resource. A tool for doctors and physicians.
While the future is promising, IBM still has a long way to go before your primary physician is an AI supercomputer.
