Variables within the National Early Warning Score, quick Sepsis-related Organ Failure Assessment and Systemic Inflammatory Response Syndrome criteria. Each variable is measured and summed up.
aNEWS ranges from 0 to 20, wherein 1 to 3 points are given for aberrant values in the following variables: body temperature, heart rate, systolic blood pressure, respiratory rate, oxygen saturation, supplemental oxygen and AVPU score.
bqSOFA ranges from 0 to 3, in which 1 point is assigned to abnormal values in the following variables: systolic blood pressure, respiratory rate and AVPU score.
cSIRS ranges from 0 to 4 points, wherein 1 point is allocated to aberrant values in the following variables: body temperature, heart rate, respiratory rate and WBC. The total score within NEWS, qSOFA, and SIRS corresponds with a risk for mortality. Abbreviations: NEWS, national early warning score; qSOFA, quick sepsis-related organ failure assessment; SIRS, systemic inflammatory response syndrome;°C, degrees centigrade; bpm, beats per minute; mmHg; millimetre of mercury; AVPU, alert, verbal, pain, unresponsive; WBC, white blood cell count.
