Brief Summary

This prospective multicenter validation study aimed to evaluate the predictive performance of a previously developed model for MDRGNB infection in ICU patients.

Conditions

Infection

Keywords

Prediction model; MDRGNB; ICU; Infection

Outcome Measures

Primary Outcomes (1)

• MDRGNB infection

  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.

  48 hours after ICU admission

Secondary Outcomes (3)

• 28-day mortality

  28 day after ICU admission

• Sequential Organ Failure Assessment (SOFA) score at 48 hours

  48 hours after ICU admission

• Adverse events related to antibiotic within 28 days

  28 day after admission

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Adult ICU patients

You may qualify if:

• Age ≥18 years;
• ICU stay ≥48 hours;
• At least one clinical microbiological specimen collected and submitted for testing within 48 hours of ICU admission, with the first submission time designated as the index time;
• Core predictive variables of the model extractable from electronic medical records or laboratory information systems.

You may not qualify if:

• For patients with multiple ICU admissions, only the first ICU stay was retained;
• Missing or indeterminate primary outcome;
• Missing key predictive variables that could not be handled according to prespecified rules.
