Typical CAP pathogens include: S pneumoniae, H influenzae, L pneumophila, M pneumoniae, C burnetii, C pneumoniae. GNB include: P aeruginosa, E coli, K pneumoniae, P stuartii. Neurological disorders include: degenerative diseases, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson disease, Down syndrome, vascular cerebral accidents, postanoxia brain injury and dementia.
CAP, community-acquired pneumonia; GNB, Gram-negative bacilli; MRSA, methicillin-resistant Staphylococcus aureus; PSI, pneumonia severity index; ‘+1 point’ indicates a PSI increase of one point.
