Latent Safety Threats and Countermeasures in the Operating Theater: A National In Situ Simulation-Based Observational Study.

The pervasiveness of LSTs suggests that our results have widespread relevance to surgical departments throughout New Zealand and elsewhere and that collective solutions would be valuable. In situ simulation is an effective mechanism both for identifying threats to patient safety and to prompt initiatives for improvement, supporting the use of in situ simulation in the quality improvement cycle in healthcare.
