测量指标:

Outcomes:

指标中文名:

一致性分析

指标类型:

主要指标

Outcome:

Agreement Analysis

Type:

Primary indicator

测量时间点:

麻醉诱导期维持期及苏醒期

测量方法:

指应用两种方法获得数据的差值(d)反映两种方法的一致性,若d服从正态分布,则95%的差值应该位于d±1.96SD区间,这个区间即为一致性界限,如果一致性界限在临床上是可以接受的,则可以认为这两种方法具有较好的一致性,可以互换使用。评估BIS与ESI数值差异的系统性偏差和随机误差。即通过偏差和精度统计比较两种麻醉深度模块的一致性。其中偏差采用均值差(Mean Difference)分析,精度统计采用一致性界限(Limits of Agreement)分析。均值差(Mean Difference)反应系统性偏差。将一致性界限不超过BIS均值的±2定义为临床可接受标准。纳入协变量指标,矫正混杂因素。按照年龄(<65岁和≥65岁)、ASA分级、BMI等进行混合效应模型矫正,通过单因素分析筛选潜在协变量。

Measure time point of outcome:

The induction, maintenance, and emergence phases of anesthesia

Measure method:

The Bland-Altman analysis was employed to assess the agreement between BIS and ESI values. This method evaluates the agreement by analyzing the differences (d) between paired measurements. If the differences are normally distributed, 95% of these differences are expected to lie within the interval of d ± 1.96SD (Standard Deviation). This interval is defined as the Limits of Agreement (LOA). If these limits of agreement are deemed clinically acceptable, the two monitoring methods can be considere
