Abstract
Background/Objectives: Enhancing delirium nursing performance in trauma intensive care units (TICUs), where the prevalence of delirium is high, causes early detection of delirium and improves the quality of nursing care. TICU nurses experience various stress levels while caring for patients with delirium, which negatively affects their performance. Self-efficacy improves delirium nursing performance based on their capacity. Person-centred care identifies the holistic needs of patients in TICUs, which stimulates their recovery. This study aimed to examine the relationship of delirium-related stress, self-efficacy, and person-centred care with delirium nursing performance and identify factors influencing delirium nursing performance among nurses in TICUs. Methods: This cross-sectional descriptive survey study was conducted on 170 TICU nurses from eight hospitals in Korea from 22 July to 30 September 2024. Data was collected using self-reported questionnaires after informed consent was provided. Data were analysed using multiple regression analysis. Results: Delirium nursing performance showed significant positive correlations with person-centred care (r = 0.51, p < 0.001) and self-efficacy (r = 0.41, p < 0.001). Regression analysis revealed person-centred care (β = 0.46, p < 0.001) and self-efficacy (β = 0.24, p = 0.004) as significant predictors of delirium nursing performance in TICUs, accounting for 28.6% of the variance. Conclusions: Interventions focused on person-centred care may help improve delirium nursing performance and practice holistic care.
