Despite growing interest in rehabilitation as a nonpharmacological intervention for delirium, the effective factors for improving delirium remain unexplored. Therefore, we aimed to investigate from various perspectives the rehabilitation factors contributing to the improvement of delirium and clarify early rehabilitation-related issues. This single-center retrospective observational study encompassed 382 patients who visited a critical care center and underwent rehabilitation from January 2018 to December 2019. Patients were included if they had delirium at the start of rehabilitation. The exclusion criteria were a ＜72-hstay, death, concomitant dementia, cerebrovascular disease, or psychiatric illness. Rehabilitation-related items were compared between patients who had delirium at discharge （n＝16） and those who did not （n＝44）. The impact of early rehabilitation was investigated using multiple logistic regression analysis. Sixty patients were included in the analyses. Multidisciplinary rehabilitation, number of days to start rehabilitation, delirium duration, and Intensive Care Unit Activity Scale as rehabilitation factors influencing delirium improvement showed significant differences. Logistic regression analysis revealed a significant association with multidisciplinary rehabilitation （odds ratio＝7.32, 95％ confidence interval＝1.59-33.72）. Although a multidisciplinary rehabilitation team is essential for rehabilitation factors to improve delirium in the intensive care unit, the lack of participation of occupational therapists and speech–language pathologists was a challenge.
