Pseudomonas aeruginosa can cause pneumonia, which may be classified as community-acquired (CAP), ventilator-associated (VAP) or healthcare-associated infection (HAI). A number of risk factors may predispose a patient to infection.
Recognized risk factors for Pseudomonas aeruginosa causing community-acquired pneumonia:
(1) COPD and/or smoking
(2) bronchiectasis (including cystic fibrosis)
(3) corticosteroid therapy
(4) intubation
(5) immunosuppression, including HIV
(6) recent antibiotic therapy
(7) enteral tube feeding
Additional factors that may be associated with Pseudomonas aeruginosa:
(1) cerebrovascular disease, including dementia
(2) outpatient bronchoscopy with a contaminated bronchoscope
(3) contaminated water supplies in proximity to patient (biofilm, etc)
