BackgroundTeaching complex motor skills at a high level remains a challenge in medical education. Established methods often involve large amounts of teaching time and material. The implementation of standardized videos in those methods might help save resources. In this study, video-based versions of Peyton's '4-step Approach' and Halsted's 'See One, Do One' are compared. We hypothesized that the video-based '4-step Approach' would be more effective in learning procedural skills than the 'See One, Do One Approach'.MethodsOne-hundred-two naïve students were trained to perform a structured facial examination and a Bellocq's tamponade with either Halsted's (n = 57) or Peyton's (n = 45) method within a curricular course. Steps 1 (Halsted) and 1-3 (Peyton) were replaced by standardized teaching videos. The performance was measured directly (T1) and 8 weeks (T2) after the intervention by blinded examiners using structured checklists. An item-analysis was also carried out.ResultsAt T1, performance scores significantly differed in favor of the video-based '4-step Approach' (p < 0.01) for both skills. No differences were found at T2 (p < 0.362). The item-analysis revealed that Peyton's method was significantly more effective in the complex subparts of both skills.ConclusionsThe modified video-based version of Peyton's '4-step Approach' is the preferred method for teaching especially complex motor skills in a large curricular scale. Furthermore, an effective way to utilize Peyton's method in a group setting could be demonstrated. Further studies have to investigate the long-term learning retention of this method in a formative setting.
