HelixTalk Episode #58 - Third time’s a charm -- redefining sepsis (again) using Sepsis-3
Date posted: March 21, 2017, 6:00 am
In this episode, we discuss the newest definition of sepsis and septic shock according to the Sepsis-3 criteria and the 2016 Surviving Sepsis guidelines. We also review the scoring systems of “qSOFA” and “SOFA” and use a patient case to help demonstrate the new definitions.
- The definitions regarding to sepsis have changed three times since 1991. The current definition (called Sepsis-3) describes “sepsis” and “septic shock”.
- “qSOFA” is a quick screening tool to quickly identify patients who MAY have sepsis. If a patient has 2 or 3 qSOFA criteria, a confirmatory “SOFA” score is required to meet the definition of sepsis.
- “SOFA” is a scoring tool that requires several lab values and vital signs that is now used to objectively define sepsis. Patients are defined as having sepsis if they have a suspected infection and an acute change of the SOFA score of 2 or more points from baseline.
- Septic shock is defined as meeting the sepsis definition (suspected infection plus a SOFA change of 2 or more from baseline) AND have hypotension requiring vasopressors to maintain a MAP >= 65 mmHg AND have an elevated lactate level (>2 mmol/L) despite having adequate fluid resuscitation.
