Rapid Identification and Susceptibility Testing of Pathogens Growing in Blood Culture Bottles - A Quality Improvement Theragnostic Stewardship Project


Rochester, Minn.

Trial status:

Open for Enrollment

Why is this study being done?

We hypothesize that the FilmArray Blood Culture ID Panel will reduce the duration of empiric broad-spectrum antimicrobial therapy typically administered in patients who have positive blood cultures, improving clinical outcome and reducing cost. To test this hypothesis we propose a prospective, randomized controlled study comparing outcomes among patients with positive blood cultures who receive either: Standard culture and antimicrobial susceptibility testing (AST) of positive blood culture bottles as is done today (control), standard culture and AST of positive blood culture bottles plus the FilmArray Blood Culture ID Panel (intervention group 1), or standard culture and AST of positive blood culture bottles plus the FilmArray Blood Culture ID Panel testing along with expert infectious diseases phone consultation (intervention group 2). In both intervention groups, results of the FilmArray test will be communicated by phone to the primary service, along with templated comments about optimal antimicrobial therapy, based on the result. (Templated comments will also be used in the control group). In intervention group 2, an infectious diseases pharmacist or physician will provide patient-specific recommendations to modify antimicrobial therapy, if appropriate, based on microbiology results and clinical information obtained through medical record review and discussion with the primary service.
