In cliot: Clinical Indices and Outcomes Tools

quick SOFA (qSOFA) Score for Sepsis

Description

Calculates the quick Sequential Organ Failure Assessment (qSOFA) score. This bedside tool identifies patients with suspected infection who are at greater risk for a poor outcome (prolonged ICU stay or in-hospital mortality) outside the intensive care unit. It uses three clinical criteria: respiratory rate, altered mental status, and systolic blood pressure.

Usage

qsofa_sepsis_score(respiratory_rate, systolic_bp, gcs_score)

Arguments

respiratory_rate	Numeric. Respiratory rate in breaths per minute. (>= 22 adds 1 point).
systolic_bp	Numeric. Systolic blood pressure in mmHg. (<= 100 adds 1 point).
gcs_score	Numeric. Glasgow Coma Scale score (3-15). (Any score < 15 indicates altered mental status and adds 1 point).

Value

A list containing:

qSOFA_Score	The calculated score (Range 0-3).
Risk_Category	"High Risk" if Score >= 2, otherwise "Low Risk".
Interpretation	Clinical guidance based on the risk level.

Examples

# Example 1: High Risk Sepsis
# RR 24 (+1), SBP 95 (+1), GCS 14 (+1)
# Score = 3

# Example 2: Low Risk
# RR 18, SBP 120, GCS 15
# Score = 0
