['The goal of this study was to determine if clinical simulation improved resident confidence in performing critical care skills, neonatal resuscitation, and colonoscopy.', 'Residents participated in clinical simulations utilizing high-fidelity medical simulators in a realistic environment. We compared resident responses on pre- and post-experience surveys.', 'Residents reported satisfaction with quality of demonstrations and opportunity for hands-on learning and practice. Residents felt more confident in their ability to apply these skills independently and in the applied context.'] Does simulation enhance resident confidence in critical care and procedural skills?
