Study Notes
Introduction to Sepsis
- Life-threatening condition caused by the body's harmful response to infection.
- Can lead to shock, multiple organ failure, and death if not recognized and treated promptly.
Definition of Sepsis
- Characterized as life-threatening organ dysfunction due to dysregulated host response to infection.
- Suspected sepsis is a syndrome, not a specific illness.
Common Sources of Infection Leading to Sepsis
- Meningitis and encephalitis.
- Pneumonia, often with chest involvement.
- Urinary tract infections, abdominal pain, or distension.
- Cellulitis, septic arthritis, and infected wounds.
- Device-related infections (e.g., urinary catheters, IV devices).
- Infection may be suspected when the source is not obvious.
Scale of the Problem
- Approximately 150,000 cases of sepsis occur annually in the UK.
- Suspected to claim 44,000 lives each year in the UK.
- Long-term complications from delayed diagnosis may cost the UK economy up to £15.6 billion annually.
Mortality Rates
- High mortality rates, with severe sepsis having a 36% death rate and septic shock up to 50%.
- Six times more likely to die from sepsis than from acute coronary syndrome (ACS) or stroke.
At-Risk Groups
- Individuals over 75 years old.
- Frail individuals and those with diabetes.
- People with weak immune systems.
- Recent surgery patients and those with serious recent illnesses.
- Individuals with breaches in skin integrity.
- Drug misusers and those with indwelling lines/catheters.
