Community-acquired pneumonia (CAP) refers to pneumonia (any of several lung diseases) contracted by a person outside of the healthcare system. In contrast, hospital-acquired pneumonia (HAP) is seen in patients who have recently visited a hospital or who live in long-term care facilities.
Generally, diseases outlined within the ICD-10 codes J12-J18 within Chapter X: Diseases of the respiratory system should be included in this category. Wikimedia Commons has media related to Pneumonia .
Community-acquired pneumonia (CAP) is infectious pneumonia in a person who has not recently been hospitalized. CAP is the most common type of pneumonia. The most common causes of CAP vary depending on a person's age, but they include Streptococcus pneumoniae, viruses, the atypical bacteria, and Haemophilus influenzae.
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 ...
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]
CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia [1] and infection of any site. [2] The CURB-65 is based on the earlier CURB score [3] and is recommended by the British Thoracic Society for the assessment of severity of pneumonia. [4]
Other organisms that cause lobar pneumonia are Legionella pneumophila and Klebsiella pneumoniae. [2] 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.
Chlamydia pneumoniae is a common cause of pneumonia around the world; it is typically acquired by otherwise-healthy people and is a form of community-acquired pneumonia. Its treatment and diagnosis are different from historically recognized causes, such as Streptococcus pneumoniae. [10]
