In contrast, hospital-acquired pneumonia (HAP) is seen in patients who have recently visited a hospital or who live in long-term care facilities. CAP is common, affecting people of all ages, and its symptoms occur as a result of oxygen-absorbing areas of the lung filling with fluid.
Pneumonia is most commonly classified by where or how it was acquired: community-acquired, aspiration, healthcare-associated, hospital-acquired, and ventilator-associated pneumonia. [42] It may also be classified by the area of the lung affected: lobar, bronchial pneumonia and acute interstitial pneumonia; [42] or by the causative organism. [82]
It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases. [2]
Cases of walking pneumonia are on the rise in children. Physicians and experts weigh in on what this means. It’s […]
Hospital-acquired pneumonia, also called nosocomial pneumonia, is pneumonia acquired during or after hospitalization for another illness or procedure with onset at least 72 hrs after admission. The causes, microbiology, treatment and prognosis are different from those of community-acquired pneumonia.
Hospital-acquired pneumonia (HAP) or nosocomial pneumonia refers to any pneumonia contracted by a patient in a hospital at least 48–72 hours after being admitted. It is thus distinguished from community-acquired pneumonia. It is usually caused by a bacterial infection, rather than a virus. [1] [2]
Streptococcus pneumoniae is the main cause of community acquired pneumonia and meningitis in children and the elderly, [5] and of sepsis in those infected with HIV. The organism also causes many types of pneumococcal infections other than pneumonia.
The pneumonia severity index (PSI) or PORT Score is a clinical prediction rule that medical practitioners can use to calculate the probability of morbidity and mortality among patients with community acquired pneumonia. [1] The PSI/PORT score is often used to predict the need for hospitalization in people with pneumonia. [2]
