This document discusses establishing a culture of safety in emergency medical services. It notes that most medical errors are due to systemic issues, not individual mistakes. A "just culture" is proposed that is not focused on blame but rather shared accountability. Under a just culture, the organization is responsible for safe systems and processes, while employees are responsible for safe behaviors. Errors are categorized as human errors from flawed systems, at-risk behaviors where risks were unrecognized, or reckless behaviors with conscious disregard for risk. Different approaches are recommended for managing each type of issue, focused on system improvements, coaching, or discipline depending on the situation. An overall goal is to establish trust so that employees feel safe providing feedback to further improve safety.
