TY  - JOUR
AB  - ObjectiveTo investigate and compare the effect of simulator training on quantitative scores for ultrasoundrelated skills for trainees with novice level ultrasound experience and expert ultrasound operators.MethodsThree novice (comprising of 11, 32, 23 participants) and one expert (10 participants) subgroups undertook an ultrasound simulation training session. Pre and posttraining test scores were collected for each subgroup. Outcome measures were as follows: mean accuracy score for obtaining the correct anatomical plane, percentage of correctly acquired target planes, mean number of movements, time to achieve image, distance travelled by probe and accumulated angling of the probe.ResultsThe novices showed improvement in image acquisition after completion of the simulation training session with an improvement in the rate of correctly acquired target planes from 28–57% to 39–83%. This was not replicated in the experts. The novice’s individual ratios based on pre vs. posttraining metrics improved between 1.7 and 4.3fold for number of movements, 1.9 and 6.7fold for distance, 2.0 and 5.2fold for time taken and 1.8 and 7.3fold for accumulated angling. Among the experts, there was no relationship between pretraining simulator metrics and years of ultrasound experience.ConclusionsThe individual simulation metrics suggest the sessions were delivered at an appropriate level for basic training as novice trainees were able to show demonstrable improvements in both efficiency and accuracy on the simulator. Experts did not improve after the simulation modules, and the novice scores posttraining were similar to those of experts, suggesting the exercises were valid in testing ultrasound skills at novice but not expert level.
