Official title
Research on the Development and Validation of an Early Prediction Model for Delirium Based on Machine Vision Analysis
Overview
Delirium has a high incidence rate and significantly affects patient prognosis. Diagnosis often relies on manual assessment, which is subject to strong subjectivity, high rates of missed diagnosis, and poor stability. This study employs non-contact identification technology based on machine vision analysis to quantitatively analyze characteristic biological feature data such as micro-expressions. It then investigates the correlation between these features and delirium subtypes. By integrating clinical phenotypic data and using machine learning algorithms, a multi-modal early prediction model for delirium is constructed to meet the clinical need for early warning of delirium subtypes and enhance the efficacy of delirium identification.
Primary outcome measures
- Number of participants with delirium as assessed by DSM-5 [Time frame: 7th day after ICU admission]
Secondary outcome measures (4)
- Accuracy [Time frame: 7th day after ICU admission]
- Precision [Time frame: 7th day after ICU admission]
- Recall [Time frame: 7th day after ICU admission]
- F1-score [Time frame: 7th day after ICU admission]
Eligibility criteria
