ABSTRACT
Before Electronic Health Records (EHRs) were available on
touch-panel tablets, doctors were confined to accessing the
records on their hospital’s computer stations, in their offices or at
nurse stations. We deployed Dr. Pad, a mobile EHR application
on the iPad, to resident doctors at the Taipei Veterans General
Hospital in Taipei, Taiwan. We are able to extract direct usage
and motion data from a large-scale in-the-wild use of a mobile
EHR by 179 resident doctors over 4 weeks. Using machinelearning
techniques, we can predict the doctors’ mobile behaviors
while using Dr. Pad, which were previously unobserved and
mainly self-reported. Our data revealed trends in the doctors’ use
of the mobile EHR, which supported claims by doctors on their
usage habits, our observations of their work routines, and even
showed that the doctors used Dr. Pad more frequently than we had
expected.
