Use of Harvey® the Cardiopulmonary Patient Simulator in Physician Assistant Training
Insights
Physician assistant students gained confidence in detecting heart murmurs after using the Harvey simulator. However, those who first attended a classroom activity performed better on a murmur identification quiz.
Area of Science:
- Medical Education
- Cardiopulmonary Simulation
- Diagnostic Skills Training
Background:
- Effective training in heart murmur detection is crucial for physician assistant (PA) students.
- Traditional classroom methods may have limitations in simulating real-world cardiac auscultation.
- The Harvey(R) Cardiopulmonary Patient Simulator offers a realistic training environment.
Purpose of the Study:
- To compare the effectiveness of the Harvey(R) simulator versus a classroom activity in improving PA students' confidence in detecting heart murmurs.
- To assess the impact of the learning sequence on diagnostic performance.
Main Methods:
- Two cohorts of PA students (n=67) participated in either a classroom heart sounds activity or the Harvey simulator first, followed by the other activity.
- Pre- and post-intervention surveys measured confidence in detecting abnormal heart sounds.
- A multiple-choice quiz assessed knowledge after the initial learning activity.
Main Results:
- Confidence in detecting abnormal heart sounds increased significantly after both activities compared to baseline.
- Following the initial activity, 85% of students in the classroom group reported confidence versus 53% in the simulator group.
- The classroom-first group achieved a higher mean quiz score (62%) than the simulator-first group (24%).
Conclusions:
- Both the Harvey simulator and classroom activity enhance student confidence in identifying abnormal heart sounds.
- A learning sequence involving the classroom activity prior to Harvey simulation leads to superior performance on a knowledge-based assessment.
- Continued integration of both teaching modalities is recommended for PA programs.
Purpose:
The purpose of this study was to evaluate physician assistant students' confidence levels in detection of heart murmurs following instruction with Harvey(R) the Cardiopulmonary Patient Simulator compared with a classroom heart sounds activity.
Methods:
Cohort 1 (n = 33) participated in the classroom heart sounds activity and then participated in the Harvey simulation exercise. Cohort 2 (n = 34) first participated in the Harvey simulation activity and then in the classroom heart sounds activity. All students completed preintervention and postintervention surveys to assess confidence in detecting heart sounds. A multiple-choice quiz was distributed to each group after participation in the first heart sounds activity.
Results:
Sixty-seven students completed all surveys. Before either activity, 6% of students in Cohort 1 and 3% in Cohort 2 reported confidence in detecting abnormal heart sounds. After completing the first activity, 85% of the classroom heart sounds activity group (Cohort 1) and 53% of the Harvey simulation group (Cohort 2) reported confidence in detecting abnormal heart sounds. The mean score on the multiple-choice quiz was 62% in Cohort 1 and 24% in Cohort 2.
Conclusion:
Both cohorts reported confidence in learning abnormal heart sounds after participation in the Harvey simulation compared with baseline confidence. Students who participated in the classroom heart sounds activity before the Harvey simulation activity performed higher on the murmur identification multiple-choice quiz. The University of Texas Medical Branch PA faculty should consider continued use of both the classroom heart sounds activity and Harvey simulation.
