Study design:

Cohort study 

研究目的:

在11家研究中心前瞻性连续纳入成人ICU患者,基于入ICU后24小时内的常规临床数据生成MDRGNB感染风险预测值,在不影响临床诊疗的前提下,在规定的阈值下(0.318),评估既往开发的MDRGNB感染风险预测模型在真实世界中的区分度、校准度与临床净获益等指标。  

Objectives of Study:

Adult ICU patients were prospectively and consecutively enrolled across 11 research centers. MDRGNB infection risk predictions were generated within 24 hours of ICU admission using routinely available clinical data. Without interfering with clinical decision-making, the study evaluated the discrimination, calibration, and clinical net benefit of a previously developed MDRGNB infection risk prediction model in real-world practice, applying the predefined threshold of 0.318.

MDRGNB infection

Type:

Primary indicator

测量时间点:

入ICU 48h时

测量方法:

本研究目的是观察入组患者是否发生早期MDRGNB感染,验证模型的性能。MDRGNB感染的发生将结合临床症状、所采集的培养结果进行综合判定。 基线与模型变量:入ICU至48h内采集。 主要结局:以首次送检标本结果判定。

Measure time point of outcome:

48 hours after ICU admission.

Measure method:

The objective of this study was to observe whether enrolled patients developed early MDRGNB infection and to validate the model's performance. The occurrence of MDRGNB infection was adjudicated by integrating clinical manifestations with culture results from collected specimens.Baseline and model variables: Collected within 48 hours of ICU admission.Primary outcome: Determined based on the results of the first submitted specimen.
