What is hospital-acquired pneumonia?

Hospital-acquired pneumonia, also called nosocomial pneumonia, is an infection that patients get while they’re in the hospital. This means the infection is not present at the time a patient is admitted to the hospital. It is considered a separate

clinical entity from CAP because the causes, microbiology, treatment and prognosis are different. Hospitalized patients have a variety of risk factors for pneumonia, including mechanical ventilation, prolonged malnutrition, underlying cardiac and pulmonary diseases, achlorhydria and immune disorders. Additionally, pathogens thrive in hospitals that could not survive in other environments. These pathogens include resistent aerobic gram-negative rods, such as Pseudomonas, Enterobacter and Serratia, resistent gram positive cocci, such as ORSA. Because of risk factors, underlying morbidity and resistent bacteria, hospital-acquired pneumonia tends to be more deadly than its community counterpart. Antibiotics used for hospital-acquired pneumonia include aminoglycosides, fluoroquinolones, carbapenems, and vancomycin. Multiple antibiotics are administered in combination in order to cover all the possible organisms effectively and rapidly, before the infectious agent can be known. Antibiotic choice varies from hospital to hospital as the likely pathogens and resistence patterns vary similarly. Symptoms of hospital acquired pneumonia may include fever, shortness of breath, and a cough that produces yellow, green, or gray sputum from the respiratory tract. Because nosocomial pneumonia is such a serious infection, patients may need to receive more than one type of antibiotic to treat it. Getting pneumonia while in the hospital may prolong the hospital stay, and intravenous (I.V.) antibiotic treatment usually lasts for up to 2 weeks. If patients begin to feel better, they may be switched from I.V. treatment to oral (tablet) treatment. Hospital acquired pneumonia occurs mostly in patients who are severely debilitated or who are immune suppressed.

More information on pneumonia

What is pneumonia? - Pneumonia is an infection of the lungs. Pneumonia is an inflammation of the lung caused by infection with bacteria, viruses, or other organisms.
What types of pneumonia are there? - Types of pneumonia are bacterial pneumonia, viral pneumonia, mycoplasma pneumonia, pneumocystis carinii pneumonia, aspiration (or inhalation) pneumonia.
What is walking pneumonia? - Walking pneumonia is pneumonia that is usually mild enough that the child does not have to stay in bed.
What is aspiration pneumonia? - Aspiration pneumonia is an inflammation of the lungs and bronchial tubes caused by inhaling foreign material.
What is bacterial pneumonia? - Bacterial pneumonia is pneumonia caused by bacteria. Streptococcus pneumoniae is the most common cause of bacterial pneumonia.
What is viral pneumonia? - Viral pneumonia is caused by various viruses. Viral pneumonia is usually milder than bacterial pneumonia.
What is bronchial pneumonia? - Bronchial pneumonia is when the pneumonia spreads to several patches in one or both lungs.
What is community-acquired pneumonia? - Community-acquired pneumonia occurs most commonly in very young and very old people.
What is hospital-acquired pneumonia? - Hospital-acquired pneumonia, also called nosocomial pneumonia, is an infection that patients get while they're in the hospital.
What is atypical pneumonia? - Atypical pneumonia is a pneumonia that does not respond to the usual antibiotic treatment.
What causes pneumonia? - Pneumonia is caused by viruses, bacteria, or parasites or other organisms such as Streptococcus pneumoniae.
What're the risk factors for pneumonia? - Alcohol or drug abuse is strongly associated with pneumonia. The elderly and infants and young children are at greater risk of pneumonia.
What're the complications of pneumonia? - Complications of pneumonia that may occur include buildup of fluid in the space between the lung and chest wall.
What are the symptoms of pneumonia? - Symptoms of pneumonia are shortness of breath, chest pain, coughing, shallow, and fever and chills.
How is pneumonia diagnosed? - The diagnosis of pneumonia is usually made from a medical history, a physical examination, and a chest X-ray.
What's the treatment for pneumonia? - Treatment of pneumonia consists of respiratory support, including O2 if indicated, and antibiotics.
How to prevent pneumonia? - Vaccines are available to protect against pneumococcal pneumonia, pneumonia caused by the bacterium.
