Abstract

Objective: To determine learnability gaps between expert and novice primary care physicians when using a computerized physician order entry (CPOE). Method: Two rounds of lab-based usability tests using video analyses with triangular method approach were conducted to analyze learnability gaps between ten novice and six expert physicians. Results: There was a 14 percent point increase in novice physicians’ task success rate (p = 0.29) and an 11 percent point increase in expert physicians’ task success rate between round one and round two (p = 0. 64). There was an 8% decrease in novice physicians’ time on task between round one and round two (p = 0. 83) and a 12% decrease in expert physicians’ time on task between round one and round two (p = 0. 47). There was a 17% decrease in novice physicians’ mouse clicks between round one and round two (p = 0. 97) and a 20% decrease in expert physicians’ mouse clicks between round one and round two (p = 0. 80). There was a 5% increase in novice physicians’ mouse movements between round one and round two (p = 0. 67) and an 8% decrease in expert physicians’ mouse movements between round one and round two (p = 0. 99). Conclusion: Future directions include identifying usability issues faced by physicians when using the EHR through subtask analysis.
