AI-based Frailty Assessment Tool for Patients Undergoing Cardiac Surgery

Frailty Assessment Tool for Patients Undergoing Cardiac Surgery Based on Artificial Intelligence Multimodal Non-contact Monitoring.

The main purpose of this study is to establish a frailty automatic evaluation index "AI frailty index" based on artificial intelligence multi-modal non-contact monitoring information analysis. At the same time, the study will explore the correlation between ' AI weakness index ' and perioperative and long-term prognosis and quality of life.

Study Overview

• Status: Completed
• Conditions: Frailty
• Intervention / Treatment: Other: No intervention

Detailed Description

This is a prospective cohort study. Patients who undergoes elective cardiac surgery will be enrolled. We collect frailty scales, clinical information and multi-modal, non-contact monitoring information during hospitalization. One-year follow-up will be done. The non-contact monitoring information are used to predict the frailty scales to establish and validate an AI-based frailty assessment model "AI frailty index". The AI frailty index will be further used to predict perioperative and long-term outcomes.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
One-dimensional matrix vector composed of five frailty scale results	Consisting of five frailty scales: Edmonton frailty scale, FRAIL frailty scale, Fried frailty scale, Clinical frailty scale, and SPPB	Before and after surgery, up to 2 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
30-day adverse events	Including death, readmission, stroke, myocardial infarction, renal insufficiency or renal failure, dialysis, atrial fibrillation, peripheral vascular embolism, bleeding events, heart failure	30 days post operative
1-year adverse events	Including death, readmission, stroke, myocardial infarction, renal insufficiency or renal failure, dialysis, atrial fibrillation, peripheral vascular embolism, bleeding events, heart failure	1 year post operative
EQ-5D score	The score of EQ-5D questionnaire	1 year post operative
QOR-15 score	The score of QOR-15 questionnaire	1 year post operative
Perioperative adverse events	Including all cause death, stroke, renal insufficiency, deep sternal wound infection, and reoperation	From surgery to discharge, up to 7 days
Area under receiver operating curve (AUC)	Area under receiver operating curve of algorithm in predicting frailty scales and outcomes	At the end of follow-up (1 mouth)
Edmonton frailty scale score	The Edmonton frailty scale consists of 11 items for a composite score of 0 to 17, and higher scores mean a worse outcome.	1 year post operative
FRAIL frailty scale score	The FRAIL frailty scale consists of 5 items, with 3 of 5 required to diagnose frailty.	1 year post operative
Fried frailty scale score	The Fried frailty scale consists of 5 items, with 3 of 5 required to diagnose frailty.	1 year post operative
Clinical frailty scale score	The Clinical frailty scale is scored 1 to 9 based on a semiquantitative evaluation of the patient's symptoms, mobility, inactivity, exhaustion, and disability for basic activities of daily living and instrumental activities of daily living, and higher scores mean a worse outcome.	1 year post operative
Short Physical Performance Battery scale score	The Short Physical Performance Battery scale consists of 3 physical tests, with each scored 0 to 4 for a composite score of 0 to 12, and higher scores mean a better outcome.	1 year post operative
