Sustained decrease in latent safety threats through regular interprofessional in situ simulation training of neonatal emergencies.

Simulation training at trainees' actual workplace offers benefits over traditional simulation-based team training. We prospectively investigated whether regular in situ simulation training of neonatal emergencies in an interprofessional and interdisciplinary team could be used to identify and rectify latent safety threats (LSTs).For this purpose, we conducted 1-day in situ simulation trainings at the Department of Gynaecology and Obstetrics, Feldbach, Austria, targeting anaesthesiologists, obstetricians, midwives, nurses and consultant paediatricians. Using published criteria for categorising LSTs, we collected LSTs, either recognised by trainers or training participants, categorised them qualitatively (, , ) and based on their potential for harm, discussed them with training participants, and reported them to hospital leadership.We conducted 13 trainings between June 2015 and April 2023, identifying 67 LSTs, most in the category of (42/67, 62.7%), followed by (14/67, 20.9%) and (11/67, 16.4%). Sixty-one (91.0%) of the LSTs could be rectified by the next training. We observed a significant negative correlation between the number of delivered trainings and the frequency of identified LSTs (Pearson correlation coefficient r= -0,684, p=0.01).While we identified a higher number of LSTs in comparison to previously published studies, regular in situ simulation training of neonatal emergencies over a period of almost 8 years positively impacted patient safety, as the majority of LSTs was rectified by the next training. Even more important, the decrease in LSTs with the increasing number of delivered in situ simulation trainings underlines the sustained effect of this educational intervention.
