definition healthcare associated pneumonia
Healthcare-associated pneumonia (nosocomial pneumonia) is pneumonia that you get when you are in a hospital or nursing home. Experts generally consider it a more serious illness than pneumonia that people get in daily life (community-associated pneumonia). This is because the person with healthcare-associated pneumonia may already have a serious illness. Healthcare-associated pneumonia is also often caused by bacteria other than Streptococcus pneumoniae, which causes most cases of pneumonia.
