For educational and professional reference only. This MODS Score Calculator is intended to assist qualified intensive care and critical care professionals. It is not a substitute for clinical judgment, bedside assessment, or institutional protocols.
The mortality estimates displayed are derived from the original Marshall et al. (1995) cohort and subsequent validation studies. They represent population-level probability estimates and must not be used to make individual patient prognosis or treatment withdrawal decisions in isolation.
The MODS score uses SI units: bilirubin and creatinine are entered in µmol/L, not mg/dL. Entering values in the wrong unit will produce invalid scores. The pressure-adjusted heart rate (PAR = HR × CVP / MAP) is a unique cardiovascular descriptor not found in SOFA or APACHE — it integrates preload, perfusion pressure, and rate simultaneously.
The MODS score was developed before the Sepsis-3 era (2016). While it remains a validated and widely cited tool in critical care research and quality benchmarking, clinicians should consider it alongside contemporaneous instruments such as SOFA, APACHE, and qSOFA for clinical decision support.
Serial MODS scoring over the ICU course provides greater prognostic value than a single admission score. Increasing scores during the first 48–72 hours correlate strongly with adverse outcome.
This tool does not store, transmit, or process any patient-identifiable information. All calculations occur locally in the user's browser. The authors assume no liability for clinical decisions made using this tool.
