Ultrasound Simulation to Improve Knowledge on the OBGYN Clerkship

Purpose: To investigate whether ultrasound (US) simulation in the OBGYN clerkship is associated with improved knowledge and satisfaction.


Background: There is rising interest in the incorporation of US into medical student education. US simulation is a powerful tool, but implementation and knowledge improvement are understudied.  


Methods: A pre-post intervention, multiple method study design was performed after IRB approval. Ten high-yield summaries were created to accompany OBGYN US simulation. Students between June 2020 and March 2021 were included with simulation introduced in November 2020. All had access to the summaries.


APGO quiz and OBGYN NBME scores were compared before and after the introduction of US simulation. An anonymous survey to assess satisfaction was administered to the simulation group. Sample size of 16 per group was needed based on APGO quiz of 80% and improvement of 5%. Descriptive statistics and t-test were used when appropriate.


Results: Ninety-nine students (70 pre and 29 simulation) were included. There was no difference in mean APGO (83.4% vs. 86.6%, p 0.88) and NBME scores (78.2% vs. 79.7%, p 0.4). Ninety-five percent felt more confident in their US skills and 61% felt that the simulation was an adequate substitute for clinical exposure. All agreed that the summary sheets were beneficial to their learning.


Discussions: Our study demonstrated that the integration of US simulation was highly rated though no improvement in APGO quiz and NBME scores was noted. US simulation did not lead to an increase in test performance, but it did show promise in replicating clinical exposure that was highly rated.
