Hospital-Acquired Pneumonia - Ventilator-Associated Pneumonia
Patients with hospital-acquired pneumonia (HAP) are those who develop pneumonia 48 hours or more after hospital admission. Ventilator-associated pneumonia (VAP) is defined as the development of pneumonia after 48 hours of mechanical ventilation. Both conditions are associated with significant morbidity and mortality and create a substantial economic burden.
Healthcare-associated pneumonia (HCAP) is no longer categorized with HAP/VAP, based on the Infectious Diseases Society of America and the American Thoracic Society (IDSA/ATS) guidelines and the closer association between HAP/VAP and multidrug resistant (MDR) pathogens.
