While initial results suggest that simulation does promote learning, there is a dearth of studies that define the extent to which skills learned through simulation are retained.
Residents skills were measured upon completion of an initial simulation training (baseline scores) and then every month for 6 months. Analysis was also performed to identify the number of iterations of practice required to regain baseline scores.
While skill scores did not deteriorate from baseline after the first 3 months (p = 0.61, p = 0.44, p = 0.2, respectively), all scores (except time elapsed) reflected significant deterioration from the fourth month onward (p < 0.05, p < 0.032, p < 0.02). However the number of practice sessions required to regain baseline scores was significantly less than that required to achieve the baseline skill set (p < 0.0003).
Skills learned through simulation show significant deterioration over long periods of time, suggesting that periodic retraining of skills may be necessary to maintain surgical proficiency.
尽管初步结果表明模拟确实可以促进学习，但缺乏研究来定义通过模拟学习的技能在多大程度上得到保留。
在完成初始模拟培训后（基线分数），居民的技能每 1 个月测量一次，共测量 6 个月。还进行了分析以确定需要多少次练习才能恢复基线分数。
虽然在前 3 个月后技能分数没有从基线下降（分别为 p = 0.61、p = 0.44、p = 0.2），但从第四个月开始，所有分数（除时间外）都显著下降（p < 0.05、p < 0.032、p < 0.02）。然而，恢复基线分数所需的练习次数明显少于达到基线技能所需的次数（p < 0.0003）。
通过模拟学习获得的技能在很长一段时间内会显著恶化，这表明可能需要定期进行技能再培训以保持手术熟练度。
