 note = {Intraosseous (IO) access can be used for the resuscitation of patients with severe traumatic injuries. However, opportunities to learn how to insert IO devices are limited for residents. The aim of this study was to perform simulated IO device placement by residents and evaluate the effectiveness of training. Residents placed IO needles into a porcine sternum under general anesthesia with guidance from an instructor. Comprehension tests and questionnaires about satisfaction and self-efficacy were conducted before and after the study. The objective evaluation was based on IO access success rate and comprehension test scores, and a subjective evaluation was obtained from questionnaire scores. Participants included 36 residents. One resident had successful clinical experience with IO access. The success rate for establishing IO access in the simulation was 100%. The rate of test completion was 100%, and that the questionnaire response rate was 61%. Mean (±standard deviation) comprehension test results improved from 9.2±0.94 to 9.6±0.79 (maximum 10; P=0.017). The questionnaire score for subjective understanding increased from 7.4±2.9 to 14±1.3 (maximum 15; P<0.0001). The score for questions specifically concerning self-efficacy increased from 1.8±0.91 to 4.1±0.64 (out of 5; P<0.0001). This simulation training improved the knowledge, subjective understanding, and self-efficacy of residents performing IO access. The success rate for confirmed IO access in this study was 100%. Simulation training may positively affect clinical performance in trauma care and requires further study.},
