Sepsis

A simple 5-point score (0 to 5) for early risk stratification in acute pancreatitis, predicting in-hospital mortality within the first 24 hours. Each criterion scores 1 point. A score of 3 or more identifies substantially higher mortality and organ-failure risk.

Mean arterial pressure estimates the average pressure driving blood to the organs across the cardiac cycle. Because diastole lasts longer than systole, it is weighted toward the diastolic pressure. A MAP of around 65 mmHg is a commonly cited floor for adequate organ perfusion in resuscitation.

NEWS2 aggregates seven routine observations into a single score that standardises how acute deterioration is detected and escalated in adults. Each parameter scores 0 to 3; the total, together with any single parameter scoring 3, determines a low, medium, or high clinical response.

Three rapidly-assessed criteria identify patients with suspected infection who are at higher risk of in-hospital death or prolonged ICU stay. A score of 2 or more should prompt escalation, lactate measurement, and a full sepsis assessment. qSOFA is a prompt, not a diagnosis of sepsis and not a screening replacement.
