Brief summary

The purpose of this European, multicentric, prospective, non-interventional study is to document and evaluate the efficacy and safety of the treatment of severely infected patients with intravenously administered fosfomycin, including patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infections, each as far as covered by the respective nationally relevant SmPC.

Inclusion criteria

* Male or female patients aged ≥ 18 years * Treatment with fosfomycin according to the (national) Summary of Product Characteristics (SmPC) of fosfomycin i.v. * Patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infection, each as far as covered by the respective nationally relevant SmPC * Written informed consent of the participant (or person in charge in case of patients incapable of giving consent)

Exclusion criteria

Design outcomes

Primary

MeasureTime frameDescription
Percentage of patients with clinical success as defined as clinical cure or clinical improvementAnalysed at EOT (End of fosfomycin treatment, up to 6 months after start of fosfomycin treatment)Definition of clinical cure (both criteria must be fulfilled): * Resolution of signs and symptoms and * microbiological cure or no additional antibiotic therapy for the targeted infection necessary. Definition of clinical improvement (both criteria must be fulfilled): * Partial resolution of signs and symptoms and * microbiological cure or no additional antibiotic therapy for the targeted infection necessary. Definition of microbiological cure: * Elimination of the relevant pathogen(s) at the relevant site(s) of infection (at least one negative culture) or * in case no sample available/indicated due to sufficient clinical response, pathogen elimination is considered. Time Frame: Time point End of fosfomycin treatment (EOT) is reached at the day of the last fosfomycin application in the course of the treatment schedule for the targeted infection (i.e., in case of a multiple stage treatment schedule, the end of the last fosfomycin treatment phase).

Secondary

MeasureTime frameDescription
Clinical success as defined as clinical cure or clinical improvementAnalysed at initial response (not later than 7 days after start of fosfomycin treatment)Definition of clinical cure (both criteria must be fulfilled): * Resolution of signs and symptoms and * microbiological cure or no additional antibiotic therapy for the targeted infection necessary. Definition of clinical improvement (both criteria must be fulfilled): * Partial resolution of signs and symptoms and * microbiological cure or no additional antibiotic therapy for the targeted infection necessary. Definition of microbiological cure: * Elimination of the relevant pathogen(s) at the relevant site(s) of infection (at least one negative culture) or * in case no sample available/indicated due to sufficient clinical response, pathogen elimination is considered. Time Frame: Time point initial response is defined to be after start of fosfomycin treatment and not later than 7 days after start of fosfomycin treatment.
