What was already known on the topic:

  • Poor usability remains a challenge for existing EHRs

  • Numerous usability methods exist that can help to detect problems in EHRs

What this study added to our knowledge:

  • User testing is more effective in detecting usability problems in an EHR compared with interviews and open ended surveys

  • Supplementing user testing with interviews and open ended surveys allows the detection of additional usability problems
