Older patients commonly have delirium-like symptoms after endoscopy with sedation. We investigated influencing factors for the onset of these symptoms by retrospective review of 230 nursing records of patients aged 65 and over.
Records were sorted by the presence or absence of delirium-like symptoms, and extracted factors were compared between the groups by a Chi-square test. Additionally, logistic regression analysis was performed using the factors as explanatory variables and presence/absence of delirium-like symptoms as objective variables.
Chi-square test results showed that those using medications which are at high risk of causing delirium tended to have delirium ? like episodes（p=0.052）．Logistic regression analysis extracted three variables as influencing factors of delirium：age（OR=1.27）sex（male）（OR=2.88），and high risk medicine（OR=3.44）．
The results suggest that older males taking high risk medicines are more likely to develop delirium-like symptom after endoscopy with sedation.
