Overview
Epidemiology
USA
- In the United States, sepsis is the leading cause of death in non-coronary ICU patients
Worldwide
- It is a major cause of death in intensive care units worldwide, with mortality rates that range from 20% for sepsis to 40% for severe sepsis to > 60% for septic shock.
Race
Commoner in African Americans compared to other races in United States.
Season
Common in winter compared to other seasons.
Risk groups
- Sepsis is common and also more dangerous in elderly, immunocompromised, and critically ill patients.
- It occurs in 1%-2% of all hospitalizations and accounts for as much as 25% of intensive care unit (ICU) bed utilization
Morbidity & Mortality
- It is the tenth most common cause of death overall according to data from the Centers for Disease Control and Prevention.[1]
- The hospitalization rate of those with a principal diagnosis of septicemia or sepsis more than doubled from 2000 through 2008, increasing from 11.6 to 24.0 per 10,000 population.
- During the same period, the hospitalization rate for those with septicemia or sepsis as a principal or as a secondary diagnosis increased by 70% from 22.1 to 37.7 per 10,000 population
- Reasons for these increases may include an aging population with more chronic illnesses; greater use of invasive procedures, immunosuppressive drugs, chemotherapy, and transplantation; and increasing microbial resistance to antibiotics (3,6). Increased coding of these conditions due to greater clinical awareness of septicemia or sepsis (12) may also have occurred during the period studied.
Cost analysis
- Total nationwide inpatient annual costs of treating those hospitalized for septicemia have been rising and were estimated to be $14.6 billion in 2008.
- Even with this expenditure, the death rate was high.
- Patients who do survive severe cases are more likely to have negative long-term effects on health and on cognitive and physical functioning.
