Most patients had serious underlying disease or other predisposing factors, 70% of the patients had cerebral vascular diseases or degenerative diseases. About three fourth of the all patients had bacterial pneumonias and the rest had acute aggravation of chronic respiratory tract infections. Causative organisms were unknown in 44.4% of the patients with pneumonia, gram-positive cocci were isolated in 11.5% of them, gram-negative rods in 26.4%. S. aureus (8.1%) and P. aeruginosa (10.2%) were the most frequent organisms causing nosocomial pneumonia. In chronic respiratory tract infections, gram-positive pathogens were dominant in causative organisms (55.3%), gram-negative cocci in 12.9%, unknown in 12.9%. Major four organisms were H. infiuenzae (20.0%), P. aeruginosa (17.6%), B. catarrhalis (9.4%) and S. pneumoniae (8.2%). Their overall mortality was 30.3%, and it was particularly high in the patients with S. aureus or glucose-non-fermentative gram-negative rods infections. The pneumonias that developed as superiufections carried a higher mortality, such as S. aureus infections (90.0%), and P. aeruginosa infections (63.0%).}, pages = {722--729}, title = {3) 当院における過去10年間の院内発症呼吸器感染症の検討(シンポジウム 院内感染と対策, 第442回新潟医学会)}, volume = {103}, year = {1989} }
