Description

This measure is used to assess the percent of patients with a severe sepsis/septic shock who had 2 sets of blood cultures collected within 24 hours following severe sepsis/septic shock identification.

Rationale

Studies show that annually there are between 500,000 to one million cases of sepsis and severe sepsis in American hospitals. The annual mortality rate for these cases is between 15 and 30 percent or as many as 200,000 deaths. Many more patients suffer from permanent organ damage. The cost to society in dollars spent and lives lost prematurely is enormous. While there are many useful clinical interventions, research shows that they are applied inconsistently, if at all.

Patients admitted to the Intensive Care Unit (ICU) with severe sepsis should have two sets of peripheral blood cultures collected immediately. Because we cannot differentiate between bacteremia and a contaminated central line, blood cultures drawn through a central line are of little value and should be avoided. All potential sites of infection should also be cultured. Source control is essential when there is a focal origin of infection.

Primary Health Components

Severe sepsis; septic shock; blood cultures

Denominator Description

Total number of patients, 16 years of age and older, with a diagnosis of severe sepsis/septic shock (see the related "Denominator Inclusions/Exclusions" field)

Numerator Description

Number of patients who had 2 sets of blood cultures collected within 24 hours prior to and 24 hours following severe sepsis/septic shock identification (see the related "Numerator Inclusions/Exclusions" field)

Type of Evidence Supporting the Criterion of Quality for the Measure

  • A clinical practice guideline or other peer-reviewed synthesis of the clinical research evidence
  • One or more research studies published in a National Library of Medicine (NLM) indexed, peer-reviewed journal

Additional Information Supporting Need for the Measure

A study confirmed that patients with severe sepsis consume significant resources. The average hospital length of stay was 20 days at an average cost of $22,100. National cost estimates for the care of severe sepsis based on this study is $16.7 billion dollars, with the care of patients older than 65 costing $8.7 billion (52.3 percent), and care of those older than 75 costs $5.1 billion dollars (30.8 percent). The costs for caring for patients with sepsis are projected to rise approximately 1.5 percent per year due to the aging U.S. population.

Inclusions
Total number of patients, 16 years of age and older, with a diagnosis of severe sepsis/septic shock*

*Refer to the original measure documentation for definitions and additional details.

Exclusions
Any one of the following:

  • Patients less than 16 years of age
  • Not Applicable because: care was withdrawn or patient expired within 24 hours following severe sepsis/septic shock identification
  • Date or Time of severe sepsis/septic shock identification unknown
  • Cases with a time elapsed EARLIER THAN -24 hours or GREATER THAN +72 hours. Time elapsed is the difference between severe sepsis/septic shock identification and the collection of two blood cultures.
