Highlights
Pneumonia is one of the types of lower respiratory tract infections (LRTI) causing mild to severe illness in people of all ages
KFUH consists of 440 beds, 42 beds are located within surgical intensive care unit (SICU) and medical intensive care unit (MICU) which are the two adults intensive care units (ICUs) in the hospital
Since there are locally limited studies on this topic in the Eastern Province of Saudi Arabia, this study aims to provide information regarding the risk factors which predispose the patients to this infection and attempt to investigate the most used antibiotic regimen in relationship to survival rate
Summary
Pneumonia is one of the types of lower respiratory tract infections (LRTI) causing mild to severe illness in people of all ages. Pneumonia is classified into different types including community acquired pneumonia (CAP), hospital acquired pneumonia (HAP), and ventilator associated pneumonia (VAP). Several types of pathogens cause nosocomial infections, Acinetobacter baumannii is one of the most significant nosocomial bacterial pathogens in hospital-acquired infections and especially in the setting of intensive care units (ICUs). This pathogen can cause many types of infections such as meningitis, bacteremia, skin infection, urinary tract infection and most commonly hospital acquired pneumonia [1, 2, 3, 4]. A national prospective surveillance study found similar results suggesting that A.baumannii is one of the main causative agents of VAP among critically ill patients [7]
