- Abstract
Purpose: To study the utility of a training session offered to junior embryologists, comparing the results obtained with those reported by a group of senior embryologists. Methods: The 62 junior embryologists participanting were asked to decide on the quality of the embryos and theg clinical decision to be taken. Results: The junior embryologists' success rate following the training course was significantly higher than before for embryo classification (48.4% ± 20.4 vs. 59.7% ±16.7) ( p < 0.05) and for clinical decision (54.7% ± 19.6 vs. 68.7% ± 17.6) ( p < 0.005). Comparison of the degree of agreement between the categories assigned by the junior embryologists and those assigned by consensus among the group of senior embryologists revealed kappa values of k = 0.32 before the course and of k = 0.54 after it. The comparison between pre- and post-training junior and senior embryologists also reflected an improvement in the kappa index for clinical decision, from k = 0.54 to k = 0.68. Conclusions: Training courses are shown to be an effective tool for increasing the degree of agreement between junior and senior embryologists.
