Abstract

Introduction Sepsis is one of the leading causes of death worldwide. There is a paucity of data describing the epidemiology of sepsis in emergency centres in developing countries. This study aims to describe the clinical profile and management of patients presenting with sepsis in this setting. Methods A retrospective chart review was conducted in an Emergency Centre (EC) of a district hospital in Durban from December 2015 to February 2016. All patients with a diagnosis of an infection that met the Surviving Sepsis Campaign criteria for sepsis syndrome were included in the study. Results A total of 1195 patients who were diagnosed with an infection were screened. Of these, 52 of them met the inclusion criteria for the study. The criteria for severe sepsis was met in 40.3% (n 23) and 1.9% (n 1) met the criteria for septic shock. More than half of the patients were HIV positive and 30.7% did not know their HIV status. The most common sites of infection were respiratory tract, gastrointestinal and central nervous system respectively. Most patients were admitted to the general medical ward. The inpatient mortality rate was 15% for general medical ward admissions. Conclusion A better understanding of the demographic and clinical profile of sepsis syndrome in South African ECs is required to guide clinical and operational policy development.

The effect of age on the development and outcome of adult sepsis.

Marc Moss, D. Mannino, Corinne S. Martin (2005)

Sepsis is an increasingly common and lethal medical condition that occurs in people of all ages. The influence of age on sepsis risk and outcome is incompletely understood. We sought to determine the independent effect of age on the incidence, severity, and outcome of adult sepsis. Longitudinal observational study using national hospital discharge data. Approximately 500 geographically separated nonfederal acute care hospitals in the United States. Patients were 10,422,301 adult sepsis patients hospitalized over 24 yrs, from 1979 to 2002. None. Incident sepsis cases were age adjusted and characterized by demographics, sources and types of infection, comorbid medical conditions, and hospital discharge status. Elderly patients (> or = 65 yrs of age) accounted for 12% of the U.S. population and 64.9% of sepsis cases, yielding a relative risk of 13.1 compared with younger patients (95% confidence interval, 12.6-13.6). Elderly patients were more likely to have Gram-negative infections, particularly in association with pneumonia (relative risk, 1.66; 95% confidence interval, 1.63-1.69) and to have comorbid medical conditions (relative risk, 1.99; 95% confidence interval, 1.92-2.06). Case-fatality rates increased linearly by age; age was an independent predictor of mortality in an adjusted multivariable regression (odds ratio, 2.26; 95% confidence interval, 2.17-2.36). Elderly sepsis patients died earlier during hospitalization, and elderly survivors were more likely to be discharged to a nonacute health care facility. The incidence of sepsis is disproportionately increased in elderly adults, and age is an independent predictor of mortality. Compared with younger sepsis patients, elderly nonsurvivors of sepsis die earlier during hospitalization and elderly survivors more frequently require skilled nursing or rehabilitative care after hospitalization. These findings have implications for patient care and health care resource prioritization and provide insights for expanded scientific investigations and potential patient interventions.

Epidemiology of severe sepsis around the world.

Derek C Angus, Claudia C. de A. Pereira, Eliézer Silva (2006)

Severe sepsis is an ongoing challenge for clinicians and health-care administrators mainly because is associated with a high incidence, mortality rate and costs. In recent years, several epidemiological studies about the incidence of sepsis have come out in different and prestigious journals. However, it is not advisable to draw direct conclusions from those studies considering methodological flaws or even different approaches. Hence, we have to be familiar with those obstacles and know how to overcome them. This review paper highlights the methods which have been used in these studies and depicts the results of occurrence rate or incidence of sepsis in countries and in intensive care units.

Epidemiology of Severe Sepsis in the Emergency Department and Difficulties in the Initial Assistance

Ederlon Rezende, João Manoel Silva Junior, Alexandre Isola … (2008)

BACKGROUND The aim of this study was to determine the occurrence rate, demographics, clinical characteristics, and outcomes of patients with severe sepsis admitted to the emergency department. METHODS A prospective study evaluating all patients admitted to the emergency department unit in a public hospital of tertiary complexity in a six-month period was conducted. During this period, the emergency team was trained to diagnose sepsis. Patients who met the diagnostic criteria for severe sepsis were followed until their discharge from the hospital. RESULTS A total of 5,332 patients were admitted to the emergency department, and 342 met the criteria for severe sepsis/septic shock. The median (interquartile range) age of patients was 74 (65–84) years, and 52.1% were male. The median APACHE II and SOFA scores at diagnosis were 19 (15–25) and 5 (3–7), respectively. The median number of dysfunctional organ systems per patient was 2 (1–3). The median hospital length of stay was 10 (4.7–17) days, and the hospital mortality rate was 64%. Only 31% of the patients were diagnosed by the emergency department team as septic. About 33.5% of the 342 severe sepsis patients admitted to the emergency department were referred to an ICU, with a median time delay of 24 (12–48) hours. Training improved diagnosis and decreased the time delay for septic patients in arriving at the ICU. CONCLUSIONS The occurrence rate of severe sepsis in the emergency department was 6.4%, and the rate of sepsis diagnosed by the emergency department team as well as the number of patients transferred to the ICU was very low. Educational campaigns are important to improve diagnosis and, hence, treatment of severe sepsis.
