title: Clinical profile and outcome of patients with severe sepsis treated in an intensive care unit in India
abstract: Sepsis is the leading cause of intensive care unit (ICU) admissions and is associated with high mortality.
  
  
  
  To identify the incidence, risk factors and outcome of patients with severe sepsis and septic shock.
  
  
  
  A prospective observational study was done in a multidisciplinary ICU over a period of 18 months. We included all adult patients admitted to ICU with features of severe sepsis and septic shock as per SCCM/ACCP guidelines. Data related to demography, co-existing illnesses, parameters to assess Acute Physiology and Chronic Health Evaluation (APACHE) II and Sequential Organ Failure Assessment (SOFA) scores, other relevant laboratory data, source of infection, organ failures and supportive measures given were recorded. Primary outcome data on mortality was collected and secondary outcome data on ventilator days, ICU length of stay (ALOS) and ventilator free days were recorded.
  
  
  
  A total of 1162 patients were screened and 356 patients had severe sepsis. Incidence of severe sepsis was 30.6% and mortality rate was 51.6%. APACHEII (23.37 ± 9.47) and SOFA (7.58 ± 4.05) scores at admission were high. Most common source of infection was from the respiratory tract (37.2%) followed by urinary tract (10.3%) and intra-abdominal (9.5%) infections. About 63% of patients required ventilator support, 25.5% of patients required vasopressor support despite adequate fluid resuscitation and one third of patients required renal replacement therapy (35.7%). Haematocrit, total leucocyte count, serum bilirubin and SOFA scores were significantly higher among non-survivors.
  
  
  
  Incidence of severe sepsis was high and was associated with a poor patient outcome in an ICU in India.
