Retrospective cohort study finds 6.8% incidence of delirium in older adults, suggesting CGA usage for risk stratification.

Post-operative delirium occurred in 6.8% of older adults, and age and cognitive status were significant predictors.
The prediction model demonstrated good calibration (p > 0.05) and an area under the curve of 0.750 (p < 0.001).
Using secondary data from 370 medical records, the analysis leveraged SPSS 20.0 and STATA 10 for data processing.
Age, cognitive and nutritional status emerged as robust predictors of post-operative delirium, highlighting the need for risk stratification.

Dinakrisma et al. (2025) studied this question.
