Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Reliability
Time Frame: Baseline Test:1 day before operation, Second Test: Day 7 after operation
|
Cronbach's alpha is used to assess the reliability and the internal consistency of this Cognitive test. Cronbach's alpha value >0.7 indicating the reliability of the test is acceptable. |
Baseline Test:1 day before operation, Second Test: Day 7 after operation
|
Validity
Time Frame: Baseline Test:1 day before operation, Second Test: Day 7 after operation
|
Content validity, Construct validity and Responsiveness analysis are used to evaluate the validity of the cognitive test. The item-content validity index (I-cvi) is used evaluate the Content validity. I-cvi≥ 0.78 means the content validity is satisfactory. The Exploratory Factor Analysis (EFA) is used evaluate the Construct validity. The Kaiser-Mayer-Olkin (KMO) index (>0.6) is used to evaluate adaptability for factor analysis. Factor loading should >0.4. The Responsiveness analysis is used to evaluate the ability of this cognitive test that can reflect the change of cognitive function of the Interviewer during operation. Paired t-test can be used to compare whether the difference in score before and after is statistically significant. P value should < 0.05. |
Baseline Test:1 day before operation, Second Test: Day 7 after operation

Time Frame |
---|---|---|
PND (Perioperative neurocognitive disorders)
Time Frame: Baseline Test:1 day before operation, Second Test: Day 7 after operation
|
PND is diagnosed by calculating the Z-score. The investigators get the score or accuracy and completion time of each test through the cognitive test network platform. Then Calculate Z-score: For each test, the mean practice effect is subtracted from the difference between preoperative and postoperative test scores; the result is then divided by the control group standard deviation to obtain a z-score. The z-scores of all tests in an individual patient are summarized and divided by the standard deviations for this sum of z-scores in the control subjects, creating a composite z-score. Cognitive decline is defined when two z-scores in individual tests or the composite z-score ≤-1.96. Perioperative neurocognitive disorders (PND) mainly refer to neurocognitive decline detected after surgery and anesthesia. |
Baseline Test:1 day before operation, Second Test: Day 7 after operation
