Overview

Investigators propose to conduct a multicenter, prospective, randomized, controlled, assessing the interests of an antibiotic protocol guided by the combined use of serum procalcitonin (PCT) and a broad-panel respiratory multiplex PCR (mPCR) to reduce duration of antibiotics exposure in patients with chronic obstructive pulmonary disease (COPD) hospitalized in intensive care unit (ICU) with pneumonia. The primary endpoint is the number of antibiotic-days for the treatment of pneumonia.
