Objective: A preoperative checklists guide was issued in 2008 by the American Society of Anesthesiologists (ASA) to improve patient safety.We aimed to determine the applicability and effectiveness of video-based feedback for the transfer of knowledge into clinical practice by using this guide.Methods: Ten anesthesia residents were divided into two groups according to their seniority, under two years and over two years.Once the preparation, anesthesia induction and airway management steps were completed, video-based feedback was given according to the ASA checklist.The knowledge level and skills of the residents were evaluated.Two months after the video-based feedback, all steps were repeated in another patient.The results were compared with a checklist score.Each guideline item was analyzed. Results:The ages of participants varied between 27-34 years (28.9±2.28 years), five were female, and five were male.Results of the pre and post video-based feedback evaluations of the residents were statistically similar in the senior and junior groups.The post-feedback achievement score in both groups was significantly higher than the pre-feedback achievement score (p<0.05). Conclusion:It has been shown that the ASA Checklist Procedure before airway management during general anesthesia induction can be successfully put into clinical practice with video-based feedback.We concluded that patient safety could be increased by the integration of this method into the routine anesthesia resident training program.
