Body surface area sounds like a geometry problem, but in practice it is a dosing number.

A preop risk calculator turns a handful of facts about a patient and a planned operation into a single risk estimate: a point score, a low/moderate/high tier, and the breakdown behind it.

Alcohol withdrawal can escalate from a tremor to seizures or delirium in hours, and managing it well depends on measuring severity the same way every time.
