Objective To understand the incidence and risk factors of nosocomial lower respiratory tract infection and provide reference for effective prevention and control of nosocomial lower respiratory tract infection. Methods The data of 294 cases of nosocomial lower respiratory tract infection from January 2007 to December 2009 were retrospectively reviewed. Results The incidence of nosocomial lower respiratory tract infection was the highest in elderly patients (52.72%), the highest in patients with primary cerebral vascular disease (24.15%), and the most important risk factor for admission to ICU (19.73%), leading to the lower respiratory tract infection The pathogen is Gram-negative bacteria (72.73%).
