Updated on 4 February 2022


This is a non-interventional medical chart review study aiming to examine the treatment patterns, effectiveness, and safety of ceftazidime-avibactam in approximately 12 countries (including but not limited to Austria, France, Germany, Greece, Italy, Spain, United Kingdom, Russia, Argentina, Colombia, Brazil, and Mexico), with possible expansion to other countries as ceftazidime-avibactam is launched. Eligible patients are adults who have been treated with ceftazidime-avibactam in routine practice at participating sites since 01 January, 2018 onwards or since the date of launch in the country if it is posterior to 01 January, 2018. As this is an observational study, patients will be treated based on the standard of care at the discretion of their physician. No drugs will be supplied for this study and patients will receive treatment through standard local practice.


This observational study will include approximately 700 hospitalized patients with a gram-negative infection, who have received at least one dose of ceftazidime-avibactam.

Patients will be recruited in approximately 62 sites across 12 countries in Europe (including Russia) and Latin America. Patients will be followed from ceftazidime-avibactam initiation until 60 days post hospital discharge, mortality, withdrawal from the study, or loss-to-follow-up, whichever occurs first.

Data will be abstracted from medical records using an electronic case report form (eCRF). Baseline data include patient socio-demographics, medical history, and clinical and microbiological characteristics of the infection treated.

Follow-up data will include details of treatment over time and clinical, microbiological, and healthcare resource utilization outcomes.

Evaluation of clinical success will be performed in patients with at least 72 hours of exposure to ceftazidime-avibactam.

Safety will be evaluated in all patients exposed to at least one dose of the product.
