  • qSOFA Quick Sepsis Assessment Explanation and Clinical Context
    qSOFA is a rapid bedside tool designed to identify patients with suspected infection who are at increased risk for adverse outcomes such as prolonged intensive care stay and mortality. The score uses three simple clinical variables which are respiratory rate of 22 breaths per minute or higher Glasgow Coma Scale less than 15 and systolic blood pressure of 100 mmHg or lower. Each variable contributes one point and the total score ranges from zero to three points. A score of two or higher suggests a significantly higher risk of poor clinical outcomes and signals the need for urgent evaluation further diagnostic testing and early sepsis management. qSOFA is not intended to replace full Sequential Organ Failure Assessment but to provide a rapid bedside screening that requires no laboratory testing.
