Time perception in shoulder dystocia management; a secondary analysis of the prospective cohort simulation SAFE study

Objective

The aim of this study was to explore and quantify the potential improvement and retention of time perception in a simulated childbirth complicated by shoulder dystocia with use of high-fidelity simulation.

Methods

This was a secondary analysis of the previously conducted prospective cohort SAFE study. Registered midwives and final year Midwifery students were invited to attend a one-day workshop in 6-monthly intervals at the University of Western Macedonia in Greece between October 2021-November 2022. There was a 30-minute initial assessment, a 30-minute theoretical and hands-on training, and a 30-minute post-training assessment on shoulder dystocia management. We identified the actual-time and the self-reported perceived-time of delivery at the start and end of each workshop and measured the difference between them to determine if there was any improvement and retention of time perception through consecutive workshops.

Results

The baseline workshop recruited 101 participants with mean age of 26.7 ± 9.8 years (range:20–59), of which 53 participated at the 6 month and 33 at the 12 month workshop. There was a significant improvement in time perception by approximately 34.8 % at the end of the baseline workshop, which was retained after 6 and 12 months. 80.2 % of participants experienced a ‘time-distortion effect’ towards the same direction and felt that the simulated delivery lasted longer than the actual time recorded by the birthing simulator. Those who were more competent at the start of the baseline workshop demonstrated a better time perception.

Conclusions

The skill of time perception in shoulder dystocia can be improved and retained through simulation training.
