                   illness_severity_moderate_severe)

Value

A list containing:

AWOL_Score

The total calculated score (Range 0-4).

Risk_Category

General classification (Low Risk < 2, High Risk >= 2).

Est_Delirium_Risk

Estimated percentage probability of developing delirium.

Arguments

age

Numeric. Patient age in years. (>= 80 years adds +1 point).

Examples

# Example 1: High Risk
# 82yo (+1), Failed spelling (+1), Oriented (0), Moderate Severity (+1)
# Score = 3 (~37% risk)

# Example 2: Low Risk
# 65yo (0), Spelled correctly (0), Oriented (0), Mild Severity (0)
# Score = 0 (~2% risk)
