With the full implementation of physician workstyle reform in 2024, task sharing in cardiovascular surgery has become increasingly important. This study conducted a nationwide questionnaire survey targeting young cardiovascular surgeons and nurses certified for specified medical acts to investigate the current status and challenges of task sharing in this field. Results revealed that while nurses were actively involved in postoperative care and certain bedside procedures, their participation in intraoperative and emergency tasks remained limited. From the nurses' perspective, concerns were raised regarding career development, compensation, and the lack of structured educational support. These findings suggest that, to ensure sustainable and effective task sharing in cardiovascular surgery, it is essential to establish clear role definitions and implement systemic organizational support for certified nurses.
