modified_sofa_score: Modified Sequential Organ Failure Assessment (mSOFA) Score

Description

Calculates the Modified SOFA (mSOFA) score, which replaces the PaO2/FiO2 ratio used in the standard SOFA score with the SpO2/FiO2 ratio. This allows for organ failure assessment without requiring arterial blood gas analysis.

Usage

modified_sofa_score(spo2_percent, fio2_percent, platelet_count, bilirubin_mg_dl,
                    hypotension_level, gcs_score, creatinine_mg_dl)

Value

A list containing:

mSOFA_Score

The calculated total score (Range 0-24).

Mortality_Estimate

Approximate mortality risk associated with the score range.

Subscores

Individual scores for each organ system.

Arguments

spo2_percent

Numeric. Oxygen saturation percentage (0-100).

fio2_percent

Numeric. Fraction of inspired oxygen (e.g., 21 for Room Air, 100 for 100%). Can be entered as percent (21-100) or fraction (0.21-1.0).

platelet_count

Numeric. Platelet count in x10^3/uL.

bilirubin_mg_dl

Numeric. Total Bilirubin in mg/dL.

hypotension_level

Numeric (0-4). Cardiovascular score based on MAP and vasopressor support: 0: MAP >= 70 mmHg. 1: MAP < 70 mmHg. 2: Dopamine <= 5 mcg/kg/min or Dobutamine (any dose). 3: Dopamine > 5 or Epinephrine <= 0.1 or Norepinephrine <= 0.1. 4: Dopamine > 15 or Epinephrine > 0.1 or Norepinephrine > 0.1.

gcs_score

Numeric. Glasgow Coma Scale score (3-15).

creatinine_mg_dl

Numeric. Serum Creatinine in mg/dL.

# Example 1: Moderate Severity
# SpO2 92% on 50% FiO2 (S/F=184 -> 3pts), Plt 120 (1pt), Bili 1.0 (0pt),
# MAP<70 (1pt), GCS 14 (1pt), Cr 1.3 (1pt)

# Example 2: Severe
# SpO2 88% on 100% (S/F=88 -> 4pts), Plt 40 (3pts), Bili 3.0 (2pts),
# Norepi >0.1 (4pts), GCS 9 (3pts), Cr 4.0 (3pts)
