Infection is an increasingly common problem in hospitalised patients in the UK. There are a variety of reasons for this problem, including the admission and treatment of ever older and sicker patients with multiple comorbidities and significant immunocomprise.
Recent figures from high-income countries calculate the incidence for sepsis to be 437 cases per 100 000 person-years. For severe sepsis the incidence is 270 cases per 100 000 person-years. Hospital mortality is around 17% for sepsis and 26% for severe sepsis [1](read details regarding the reference).
