BackgroundUmbilical cord prolapse is a rare obstetric emergency requiring rapid coordination of a multidisciplinary team to effect urgent delivery. The decision to delivery interval (DDI) is a marker of quality of teamwork. Multidisciplinary team simulation-based training can be used to improve clinical and teamwork performance.AimTo assess the DDI for cord prolapse before and after the introduction of simulation-based training at a quaternary maternity unit in Australia.MethodA retrospective, observational cohort study comparing the DDI before and after the introduction of simulation-based training activities. The general linear model was used to estimate the association between DDI and simulation training while adjusting for potential confounders including model of care (public or private) and time of birth (regular or after hours).ResultsAfter the introduction of simulation training, mean DDI decreased by 4.1 min (difference −4.1, 95% CI −6.2 to −1.9), after adjustment for confounding factors. Despite this, there was no difference in selected neonatal outcomes including Apgar score at 5 min and arterial cord pH.ConclusionsThe introduction of simulation-based training was associated with a decrease in the DDI in the setting of cord prolapse.
