Purpose This study aimed to investigate the incidence rate, types and risk factors for delirium in patients admitted to the surgical Step-Down Unit (SDU).
Methods This study was a retrospective study of the electronic medical records of patients admitted to a surgical SDU from February 2020 to July 2020. The delirium assessment was conducted using the short Confusion Assessment Method (a tool that allows quick and easy screening of delirium) and the incidence and risk factors for delirium were determined.
Results Among a total of 227 patients in the study, the incidence rate of delirium was 35 cases (16.7%). It predominantly occurred on the first day (n = 16, 45.7%) and the second day of admission (n = 15, 42.8%). The peak occurrence of delirium was between 14:00 and 22:00 (n = 30, 85.7%). The most common type of delirium was hypoactive (n = 19, 54.3%). The results of multiple logistic regression analysis indicated that the factors influencing the occurrence of delirium in the surgical step down unit (SDU) were age, hypertension, stroke, white blood cell count, and the use of restraints.
Conclusion Considering the characteristics of high-risk groups for delirium in the surgical SDU, it is necessary to establish nursing practice guidelines to minimize delirium.

The elderly population experiences a normal, age-related decline of physiological function in all major organ systems. The age-related changes in lung structure include decreases in chest wall compliance, respiratory muscle strength and elastic recoil, contributing to decreased lung function which increases susceptibility to infection. The age-related changes in cardiovascular structure and function increases the risk of cardiovascular disease. The aging process in the kidney leads to several clinical conditions in the elderly such as impaired drug metabolism and kinetics, loss of homeostasis, and electrolyte abnormalities. With aging, the decrease in gastrointestinal (GI) function in the mouth, esophagus, stomach, small and large intestine, and liver may affect appetite, motility, enzyme and hormone secretion, nutrient digestion and absorption, and gastrointestinal immunity. These changes in GI function may play a significant role in malnutrition and an increased risk of cachexia. Aging leads to inevitable deterioration in cellular and physiological function, which result in impaired homeostasis, decreased ability to adapt to stress, increased vulnerability to disease, and increased age-related mortality. Optimal health care management requires a deep understanding of the normal physiological changes associated with aging, and is necessary to provide insight into the mechanisms of multiple organ impairment and disease in the elderly.
