Sedation for invasive procedures is given for various clinical purposes to patients of all ages worldwide. However, sedation is a continuum to general anesthesia and contains severe inherent risks leading to mortality. Providing a simulation-based sedation training course (SEDTC) to various medical staff could be an effective strategy to improve patient and medical safety associated with sedation. The SEDTC generally includes basic airway management such as upper airway obstruction release or rapid response action toward excessive sedation, utilizing problem-based learning or simulators. However, participation alone in the SEDTC can only achieve Level 1 (reaction) or 2 (learning) in the Kirkpatrick model. A patient safety improvement of Level 3 (transfer) or 4 (result) of the Kirkpatrick model can be achieved when all members related to sedation undergo experiential learning and reach a consensus. Accordingly, in-hospital interprofessional SEDTC focusing on a resilience approach is essential to achieve effective sedation patient safety in Level 3 or 4 of the Kirkpatrick model.
