Anyone who would routinely choose against two-to-one odds would have to be considered crazy, right? Well, at least a third of Americans regularly take their chances when it comes to diagnosing symptoms. In a recent study reported in JAMA that compared diagnosis accuracy, it was discovered that physicians correctly diagnosed a patient 72% of the time, whereas computer apps did so 34% of the time. One major factor in the difference was the ability for doctors to reference patients’ medical histories. So, what could computers do if armed with more electronic health records? Well, IBM’s supercomputer “Watson” solved a months-old, doctor-stumping leukemia mystery in 10 minutes. Look for more calls from private app developers to tie into EMR data. That shouldn’t make us nervous, right?
