ABSTRACT
PURPOSE:
To investigate how the extent of an ultrasound instructor's clinical expertise influences the level of hands-on ultrasound competency achieved by clinicians after three-day ultrasound courses in abdominal and emergency ultrasound. The second goal was to determine how physicians in residency rate the sonographic and didactic skills of student instructors compared to medical staff instructors.METHOD:
A total of Nâ=â100 residents participating in a 3-day ultrasound workshop were randomly trained either by 15 student instructors or by clinical staff physicians, both with >â2 years of teaching experience. Both instructor groups had previously completed 120 hours of didactic instructor training. Ultrasound competencies were assessed by a standardized objective structured clinical examination (OSCE) of healthy individuals. The sonographic and didactic skills of both instructor groups were rated by questionnaires with six-step Likert items (1â=âexcellent, 6â=âpoor).RESULTS:
The cohort, trained by student instructors, achieved the same scoring level as the second cohort, trained by physician instructors (mean score 76.4, versus 73.7 of max. 100 points, pâ=â0.28) in the final OSCE. The sonographic qualification was rated for student educators as 1.44 (mean) [1.1-1.62], versus residents 1.46 [1.26-1.61], versus attendings 1.29 [1.05-1.61]. Didactic skill levels were rated without significant differences with means of 1.53, 1.57 and 1.53, respectively. DISCUSSION &CONCLUSION:
The didactic competence of student instructors does not differ statistically from the competency levels of experienced physicians. In terms of the acquired ultrasound skills of trainees, our data indicate that student instructors can be as efficient as staff instructors. Therefore, student instructors can be employed as resource-saving ultrasound educators without decreasing the skills level achieved by course participants, provided that they previously underwent a comprehensive didactic and sonographic training program.
