In-situ simulations to detect patient safety threats during in-hospital cardiac arrest.
In situ simulation is a valuable tool to identify latent safety threats. In this study, 36 unannounced in situ in-hospital cardiac arrest (IHCA) simulations were conducted across 4 hospitals and identified 30 system errors. Errors were categorized as involving human, organization, hardware, or software errors. These system errors contributed to treatment delays and care omissions.
