The electronic health record (EHR) systems now used in the vast majority of U.S. hospitals and physician offices get an average grade of “F” on the usability scale in the results of a newly published survey of nearly 900 doctors. Given that EHR work gobbles up as much as two hours of physicians’ time for every one hour they spend delivering patient care, that result is grimly unsurprising.

After researchers adjusted for physician respondents’ age, gender, medical specialty, practice setting, and hours worked, they found that how well doctors rated their EHRs’ usability was “independently associated with the odds of burnout,” according to a study published today in Mayo Clinic Proceedings.

My lede. The whole shebang.
