cirs_geriatric_score: Cumulative Illness Rating Scale for Geriatrics (CIRS-G)

Description

Calculates the CIRS-G score, a comprehensive method for quantifying the burden of chronic illness in geriatric patients. The scale evaluates 14 body systems, each rated from 0 (None) to 4 (Extremely Severe), providing a total score and severity index.

Usage

cirs_geriatric_score(heart, vascular, hematopoietic, respiratory, eent,
                     upper_gi, lower_gi, liver, renal, gu, msk, neuro,
                     endocrine, psych)

Value

A list containing:

CIRS_G_Total_Score

Sum of all items (Range 0-56).

Severity_Index

Total score divided by the number of categories (14).

Number_of_Categories_Endorsed

Count of systems with a score > 0.

Details

General Scoring Guidelines: 0: None. 1: Mild (Impairment does not interfere with normal activity). 2: Moderate (Impairment interferes with normal activity; meds may be needed). 3: Severe (Significant disability; chronic problems are uncontrollably). 4: Extremely Severe (Life-threatening; emergency treatment required).
