A severity score that cannot be audited is a number, not an instrument. In intensive care, numbers move decisions: who gets reviewed first, who gets escalated, what the unit tells the family. That weight demands that every score show its work.
The problem with black box scoring
Most tools give you a total. APACHE II 22. SOFA 9. The clinician is left to trust that the banding behind it was implemented correctly, that the creatinine was doubled for acute renal failure, that the oxygenation branch used the right variable for the FiO2. Errors in these details are common, silent and consequential.
The published rubrics are public. Knaus and colleagues published APACHE II in 1985. Vincent and colleagues published SOFA in 1996. The Royal College of Physicians published NEWS2 in 2017. There is no excuse for hiding the arithmetic.
What showing the work looks like
UltraCare renders every score as a breakdown: variable, the charted value, and the points it contributed. When a value changes, the row that moved is highlighted. The clinician can disagree with an input in seconds, because the input is visible.
- Every variable is listed with its charted value and its points.
- Every band comes from the primary source, cited on the card.
- Every recomputation happens on charted values, deterministically. Same inputs, same score, every time.
Decision support earns trust the same way a colleague does: by showing its reasoning.
Try it yourself
Our free calculators implement the exact published rubrics with the full breakdown visible, and our evidence page lists every primary citation. Inside the UltraCare workspace the same engine recomputes on every charted value, admission to discharge. The clinician stays in control.
