Epidemiology
Percentage of adults aged 65 and over who had ever received a pneumococcal vaccination: United States, 1997–2012 Graph obtained from CDC [1]
As many as 400,000 hospitalizations from pneumococcal pneumonia are estimated to occur annually in the United States. Pneumococci accounts for about 30% of adult community-acquired pneumonia. [2]
In 2012, 59.9% of adults 65 years and older received a pneumococcal vaccination.[3]
In 2010, the number of discharges for patient admitted with pneumonia in hospitals in the US was 1.1 million patients. The average length of stay for pneumonia patients admitted to hospitals was 5.2 days.[3]
An increasing rate of CAP is seen with age. Approximately 5 to 6 cases of pneumonia per 1000 persons are observed among adults. A pronounced seasonal effect on the number of patients presenting to the emergency department is also noted. During the winter months, there is an approximately 50% rise in the number of cases compared to the summer months.[4]
About 3.5 million deaths yearly have been attributed to lower respiratory tract infections (LRTI). LTRIs are the third most common cause of overall death and the leading cause of death from infectious diseases worldwide.[6]
Pneumonia is the ninth leading cause of death in the United States.
The number of deaths in the US in 2011 attributed to pneumonia was 52,294. [3]
Pneumonia mortality rate was 16.8 deaths per 100,000 in the US in 2011. [3]
A higher mortality rate is seen in invasive diseases, nursing home patients and severe bacteremia.
More than 40 % mortality rate is seen in ICU admitted patients.
The percentage of hospital inpatient deaths from pneumonia in the US 2006 was 3.4%. [7]
Age
Individuals older than 85 years of age are at a particularly high risk of developing CAP that can reach an annual rate of 5-10%.[8]
Individuals younger than 3 years and older than 65 years of age are more likely to be hospitalized with severe symptoms and complications.
Gender
The risk of CAP is similar in males and females.
