Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to compare 28-day mortality among patients with carbapenem resistant A. baumannii infections in two hypothetical target trials where patients receive 7 days of a cefiderocol-based treatment strategy or 7 days of a best available therapy treatment strategy.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Reciept of cefiderocol

Inpatients with carbapenem-resistant Acinetobacter baumannii infection that receive empiric and/or targeted therapy including cefiderocol.

No interventions assigned to this group

Reciept of best available therapy (BAT)

Inpatients with carbapenem-resistant Acinetobacter baumannii infection that receive empiric and/or targeted therapy with activity against the infection but does not include cefiderocol

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Hospitalized adults (≥ 18 years of age)
* Carbapenem resistant A. baumannii-calcoaceticus complex clinical culture
* Antimicrobial agent with possible in vitro activity against carbapenem resistant A. baumannii-calcoaceticus complex initiated in the time frame of 2 days before culture collection until 2 days following first available antibiotic susceptibility test result being made available

Exclusion Criteria

* Patients with no antibiotic susceptibility testing
* Patients with only A. baumannii infection diagnosed by rapid diagnostic tests (i.e., multiplex polymerase chain reaction)
* Initiation of antimicrobial agent outside of selected time frame (i.e., 2 days before culture collection until 2 days after first available antibiotic susceptibility test result was made available)
