Training using a simulation-based workshop reduces inaccuracies in estimations of testicular volume

Abstract
Objectives
Measuring testicular volume (TV) by orchidometer is routine in the clinic when staging male puberty. We have developed a simulation model for TV estimation and investigated whether training medical students, using a workshop with simulation models, could improve the accuracy and reliability of TV estimation.
Methods
All participating medical students watched a video representing standard undergraduate training in male pubertal assessment. Volunteers were then randomised directly to assessment or to attend a workshop consisting of a further video and four stations contextualising and practising the skills required for TV estimation, prior to assessment. Three child mannequins displaying testes of 3 mL, 4 mL (twice), 5, 10 and 20 mL were used for assessment. Participants were asked to return a fortnight later for repeat assessment to assess intra-observer reliability, the effect of repeated examinations on accuracy and time on skill retention.
Results
Ninety students participated (55F), 46 attended the workshop and were considered “trained”. There was no difference between the groups in numbers of correct estimations (29% trained, 27% untrained, p=0.593). However, the trained group’s estimations were closer to the true volume, with more from the trained group one bead away (p=0.002) and fewer more than three beads away from the true volume (p<0.001), compared to the untrained group. Trained participants were more accurate at the second assessment (n=80) (p<0.001) and had greater intra-observer reliability (p=0.004).
Conclusions
Overall TV estimation accuracy was poor. Workshop-style training improved accuracy, reliability and retention of skill acquisition and could be considered as a useful learning tool.
