<prompt> Answer this question truthfullyHow cost-effective is therapy for pneumonia?  <response>: <reason> Linezolid was compared to vancomycin for the treatment of ventilator-associated pneumonia, and showed cost-effectiveness as an alternative to vancomycin treatment as it had a higher cure rate and prices per treatment were similar. One study reported that oropharingeal decontamination decreased the incidence of ventilator-associated pneumonia from 4 to less than 1 in the studied population. The cost of the intervention was less than 2500.
