This study aimed to investigate factors affecting behavioral intentions to use defibrillators among clinical nurses in South Korea, using a modified predictive technology acceptance model 2 (TAM 2) that facilitates understanding of what prompts apparent spontaneous actions. This descriptive, cross-sectional study included 467 clinical nurses with more than 6 months of clinical experience. The path analysis results showed that the variables directly affecting the intention to use a defibrillator among clinical nurses were the image, organizational support, perceived ease of use, and perceived usefulness. Moreover, job autonomy and total career indirectly affected the intention to use a defibrillator. Clinical nurses need to know how to use defibrillators and be able to act promptly on patients with in-hospital cardiac arrest (IHCA). Organizational managers need to improve the work environments of clinical nurses accordingly. Additionally, it is necessary to establish a policy foundation to ensure the development of competence and job autonomy that can lead to the use of defibrillators by improving various factors, including anxiety or reluctance of nurses to use defibrillators in acute cardiac arrest.
