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)

Arguments

heart	Numeric (0-4). Heart disease severity.
vascular	Numeric (0-4). Vascular disease severity.
hematopoietic	Numeric (0-4). Hematopoietic system severity.
respiratory	Numeric (0-4). Respiratory system severity.
eent	Numeric (0-4). Eyes, Ears, Nose, Throat, Larynx severity.
upper_gi	Numeric (0-4). Upper GI severity.
lower_gi	Numeric (0-4). Lower GI severity.
liver	Numeric (0-4). Liver severity.
renal	Numeric (0-4). Renal severity.
gu	Numeric (0-4). Genitourinary severity.
msk	Numeric (0-4). Musculoskeletal/Integumentary severity.
neuro	Numeric (0-4). Neurological severity.
endocrine	Numeric (0-4). Endocrine/Metabolic severity.
psych	Numeric (0-4). Psychiatric/Behavioral severity.

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).

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.
