Abstract

Assessing available information on the burden of sepsis: global estimates of incidence, prevalence and mortalityObjective Sepsis is a complex and hard-to-define condition with many different interactions with other disorders.Presently, there are no estimates of the burden of sepsis and septicaemia at the global level and it was not included in the initial Global Burden of Disease study.Non-maternal sepsis has only recently received attention as a substantial global public health problem.The aim of this study was to assess available data on the burden of non-maternal sepsis, severe sepsis and septic shock in the community and to identify key gaps in information needed to estimate the global burden of sepsis.Methods Literature review of English language-based studies reporting on the incidence, prevalence, mortality or case-fatality of sepsis, severe sepsis and septic shock.The available literature was searched using the MEDLINE database of citations and abstracts of biomedical research articles published between 1980 and 2008.Findings 8 studies reported incidence of sepsis, severe sepsis or septic shock at the national level (4 from the USA and 1 from Brazil, the UK, Norway and Australia).No studies on the incidence, prevalence, mortality or case-fatality from sepsis in developing countries were found.The population sepsis incidence ranged from 22 to 240/100 000 (most plausible estimates ranged from 149 to 240/100 000); of severe sepsis from 13 to 300/100 000 (most of the estimates were between 56 and 91/100 000); and of septic shock 11/100 000.Case-fatality rate depends on the setting and severity of disease.It can reach up to 30% for sepsis, 50% for severe sepsis and 80% for septic shock.While the data were compiled using strict inclusion and exclusion criteria, a degree of uncertainty still exists regarding the reported estimates. ConclusionThe few national-level reports available allow only a very crude estimation of the incidence of sepsis in developed countries while there is apparent lack of data from developing countries.A clear and universal definition of sepsis as well as the development of a sound epidemiological framework to begin addressing the magnitude of this problem is urgently needed through research in developing countries.

Figures

Figure 1 Natural history of sepsis diagram. Key to the diagram: 1) Potentially modifiable risk factors that increase the probability of infection, SIRS and sepsis in a non-diseased population or severe sepsis and septic shock in septic patients; 2) Incidence of sepsis: the rate at which susceptible or exposed individuals become newly affected by sepsis; 3) Remission: the rate at which individuals with sepsis stop being a sepsis case; 4) Sepsis-complication: the rate at which patients experience a complication of sepsis or start to suffer from sequelae of sepsis; 5) Case-fatality (or population mortality rate or relative risk of dying): the rate at which patients die from sepsis; 6) Complication-fatality: the rate at which patients die as a result of a complication of sepsis; 7) Individuals with sequelae who are exposed to the risk factor(s) and are susceptible to acquire infection, SIRS, sepsis, severe sepsis or septic shock again; 8) General mortality: the rate at which the population dies from any condition other than sepsis. Infection has been defined as a pathological process caused by invasion of normally sterile tissue/fluid/body cavity by pathogenic microorganisms; Systemic inflammatory response (SIRS) is a systemic inflammatory state characterized by changes in body temperature, heart rate, respiratory rate and leukocyte blood count; Sepsis is defined as confirmed or suspected infection and SIRS; Severe sepsis is defined as sepsis complicated by organ dysfunction; Septic shock in adults is defined as state of acute circulatory failure characterized by persistent arterial hypotension unexplained by other causes. Paediatric septic shock is defined as tachycardia with signs of decreased perfusion including decreased peripheral pulses, altered alertness, and cool extremities or reduced urinary output. Hypotension occurs later than in adults and is a sign of late and decompensated shock in children [3,4].

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
