Purpose This study compares burnout, accountability, nursing competency, and quality of nursing services among nurses through the nursing care models and work experience. Methods: A cross-sectional study was conducted on 129 nurses working for more than six consecutive months in a tertiary hospital in South Korea. Data were collected in August 2023 using the Shirom-Melamed Burnout Questionnaire, Specht and Ramler Accountability Index, Nurse Competence Scale, and Good Nurse Care Scale. Differences between nursing care models were analyzed using an independent t-test. Results: Nurses in the team nursing method demonstrated lower levels of burnout and higher levels of accountability, nursing competency, and quality of nursing services than those in the functional nursing method. All differences were statistically significant, except for accountability. Novice and advanced beginner nurses showed statistically significant differences in burnout; competent and proficient nurses showed statistically significant differences in accountability, nursing competency, and quality of nursing services, excluding burnout; and expert nurses showed no statistically significant differences in nursing performance by nursing care model. Conclusion: The team nursing method showed better results in addressing nurses’ burnout, accountability, nursing competency, and quality of nursing services. The team nursing methods meet the needs of nurses seeking the total care of patients.
