Abstract
The purpose of this research is to make the 2008 version of assessment sheet which can predict the delirium after the operation, and find out the validity. The research method starts to investigate actual conditions of the appearance of delirium after the operation, make a delirium assessment sheet after the operation, and finally show the validity. A multiple regression analysis was done to find out the correlation of presence and the assessment sheet item on the appearance of delirium. The disease probability was calculated by using the sigmoid function from the change in the delirium appearance and the score of the assessment sheet as a delirium risk after the operation. As a result, the following two points became clear. (1) As delirium appearance of disease factor, the order was "Understanding", "ICU entering ", "Art type", and "Age" as the partial regression coefficient. (2) The disease rate in "High risk" group goes high, and the sensitivity to judge the disease goes high. Therefore, it is suggested that the 2008 version assessment sheet is more useful to predict the appearance of delirium after the operation.
