A definitive diagnosis of pneumonia comprises four aspects: (i) symptoms and signs of a respiratory tract infection, (ii) radiological changes, (iii) identification of a putative pathogen and (iv) a treatment response, or clinical course, consistent with pneumonia. A meta-analysis of individual participant data from 26 RCTs found that PCT-directed treatment in the management of acute respiratory tract infections (of varying types and severity, including CAP and HAP) was associated with a reduction in antibiotic exposure (5.0 vs. The respiratory pathogens commonly implicated in patients with CAP remain important aetiological agents in all other types of pneumonia, including HAP and pneumonia in the immunocompromised host (Table 8 ).	./cache/cord-260679-tm1s6wvj.txt	./txt/cord-260679-tm1s6wvj.txt
