About

This study will describe clinical outcomes in patients who received ceftolozane-tazobactam for a Pseudomonas aeruginosa infection. Primary outcomes include 30-day and in-hospital mortality.

Full description

Very little data is available to evaluate the use of ceftolozane-tazobactam in MDR Pseudomonas aeruginosa infections. Additionally, there is currently no standard recommendation for the treatment of MDR Pseudomonas aeruginosa infections, and multiple agents are often used in combination which increases the probability of adverse effects in addition to leading to possibly more resistance and higher costs of care. This is particularly relevant since the primary alternative drugs for MDR Pseusomonas aeruginosa infections are aminoglycosides and polymyxins, two categories of agents with significant adverse effects and suboptimal pharmacokinetics that limit efficacy. This is a multicenter study designed to collect retrospective data on clinical outcomes of patients treated with ceftolozane-tazobactam in the hospital. The primary outcomes include 30-day and in-hospital mortality. Microbiological and clinical cure will be assessed as secondary outcomes. Microbiological outcomes will be defined as: cure- a repeat culture was negative; failure- repeat cultures were not negative or the patient died before repeat cultures could be obtained; presumed cure- repeat cultures were not taken but clinical cure occurred. Clinical outcomes will be defined as: clinical success- signs and symptoms o the index infection resolved at the end of therapy; clinical failure- signed and symptoms remained at the end of therapy or the patient died; indeterminate- it was not possible to determine the clinical outcome at the end of therapy. Patient information will be collected from Temple University Hospital as well as 20 other hospital sites. The source population will be all adult patients who received ceftolozane-tazobactam for greater than 24 hours in each of the hospital sites between December 19, 2014 and December 31, 2016. Participating hospital sites will review clinical charts to identify and enroll a target of 5-15 subjects per site. We have a targeted enrollment of 200 subjects. All involved parties will use the Research Electronic Data Capture (RedCap) database based at Temple University for data collection and storage. We will be utilizing existing electronic data and will have no direct contact with or recruit research subjects. Because this is a study with retrospective data collection, enrolled patients will have received treatment as determined by the treating physicians in accordance with standard of care. To limit bias in the selection of subjects, investigators will be asked to identify and consecutively enroll all eligible patients treated with ceftolozane-tazobactam within the study period.
