Web Calculator of Delirium Risk Index

This web calculator helps calculate Delirium Risk Index (DRI), a comorbidity-based predictive index to predict the risk of post-operative delirium, The DRI was originally derived based on the data of 506,438 hip-fracture surgeries from the Premier Healthcare Database, and then validated using data of 1,130,569 knee arthroplasty surgeries. Details of derivation and validation see Zhong et al. (2020) as follow:
