“…These results may be attributable to the differences in the development and duration of implementation, operating system, organizational culture, targeted departments and various environmental factors, considering that tertiary university hospitals developed a system over 5 years or more, preliminarily ran the programme for a year and then applied it for more than 5 years (Chae et al, 2015;Filani et al, 2019;Meucci et al, 2019;Moore et al, 2019). The scores for the sub-categories of the Korean Perception of Career Ladder System Scale differed across studies, where the score for the perception of expected outcome category was the highest in the study by Park and Lee (2010), while that for the general understanding of the clinical ladder system categories was the highest in the studies by Chae et al (2015) and Kim et al (2018), similar to this study.…”
