Development of Perioperative Delirium Prediction Model

The development group comprises 385 individuals. Following the data collection phase of the development group, the independent risk factors for the onset of delirium will be identified through statistical analysis. A delirium prediction model will then be constructed using the identified risk factors.

The validation group comprises 385 individuals. The delirium prediction model created using the data from the development group will be validated by testing the data from the validation group. This will enable the evaluation of the model's fit and calibration in predicting delirium.
