Novel modified Peyton's approach for knowledge retention on newborn life support training in medical students

Abstract

Aim: We sought to improve retention of neonatal resuscitation skills by modifying step 3 through additional functional verbalisation in Peyton's four-step approach (P4S).

Methods: Newborn life support (NLS) training was performed in a simulation-based setting. In contrast to the traditional approach, students taught with the modified approach were requested to explain every step of their performance in Peyton's step 3. A total of 123 students were allocated into both experimental groups. Students were then assessed by megacode on day four (initial assessment) and 6 months (follow-up assessment).

Results: Both groups showed similar scorings in the initial, follow-up assessment and in mean change. On initial megacode, time to start with initial inflation and post-resuscitation care was significantly faster in the control group. All showed a significant loss of performance irrespective of modification in step 3 in the follow-up assessment. Only time until start with post-resuscitation care shows a significant group difference in mean change between initial and follow-up with increasing time in the control and decreasing time span in intervention group.

Conclusion: Both methods showed equal levels of knowledge acquisition and long-term decline in NLS performances. Verbalisation in step 3 influenced speed of applied NLS performance.
