Cost-effectiveness of the rapid detection test for methicillin-resistant Staphylococcus aureus (MRSA) in the bronchial samples of patients with suspected ventilator-associated pneumonia. The x-axis represents the prevalence of MRSA. The y-axis represents the change in total cost (antimicrobial therapy and rapid diagnostic test) associated with the use of the test (in Euros). Cost is based on consecutive use in 100 patients.
