Hospital acquired pneumonia is the second most common nosocomial infection (after urinary tract infections) and accounts for 15–20% of the total. [1] [2] [3] It is the most common cause of death among nosocomial infections and is the primary cause of death in intensive care units.
Pneumonia is the most common hospital-acquired infection that causes death. [29] Before the advent of antibiotics, mortality was typically 30% in those that were hospitalized. [22] However, for those whose lung condition deteriorates within 72 hours, the problem is usually due to sepsis. [41]

[13] [14] The most common treatment is antibiotics and these vary in their adverse effects and their effectiveness.
Like other types of pneumonia, lobar pneumonia can present as community-acquired, in immune-suppressed patients, or as a nosocomial infection. However, most causative organisms are of the community-acquired type. Pathological specimens to be obtained for investigations include: Sputum for culture, AAFBS, and gram stain
