A Smartmed interactive tool
PIM3 Checker.
Every step, explained.
Explore the PICANet-team 2013 equation or the supplied 2024 comparison. See every contribution to the calculation.
Explore an admission
Use the first eligible observations, from first specialist contact to one hour after PICU arrival.
Original PIM3 equation with explicit missing-value defaults.
Use a contemporaneous arterial pair on eligible oxygen delivery, following the PIM3 coding rules. SpO₂ is not a substitute for PaO₂.
Admission and diagnostic context
Choose the highest qualifying diagnostic category for the selected model, using its coding rules. Fixed pupils exclude findings due to drugs, toxins or local eye injury. Refer to the linked coding rules for full definitions.

Research / educational showcase. PIM3 is intended for group-level risk adjustment; use trained coding and independently validated software for clinical or audit submissions.
Original PIM3 equation, plus a separately labelled 2024 recalibration comparison. Educational model exploration; not an individual prognosis.
What this PIM3 calculator shows
The checker separates the 2013 reference equation from the supplied 2024 comparison. It shows the linear predictor, model estimate and contribution from each input. Choose a sample scenario or change an input to see how the breakdown changes.
Check the version and input units
The interface labels blood pressure, base excess, oxygen inputs, admission context and diagnostic categories. Missing-value defaults depend on the selected version. Read the equation breakdown and the linked PICANet guidance when exploring a result.
Scope of the result
This is an educational software showcase for group-level case-mix and audit exploration, not an individual prognosis. It runs in your browser without patient identifiers, saving or submissions. Clinical or audit submissions require trained coding and independently validated software.
