What it calculates

The “Charlson Comorbidity” calculator computes Charlson Comorbidity Index from 17 parameters: age (years), history of myocardial infarction (1 = yes), congestive heart failure (1 = yes), peripheral artery disease (1 = yes), stroke or tia (1 = yes), dementia (1 = yes), chronic pulmonary disease (1 = yes), connective tissue disease (1 = yes), peptic ulcer disease (1 = yes), liver disease (0 none, 1 mild, 2 moderate/severe), diabetes (0 none, 1 uncomplicated, 2 end-organ damage), hemiplegia (1 = yes), moderate/severe ckd (1 = yes), solid tumor (0 none, 1 localized, 2 metastatic), leukemia (1 = yes), lymphoma (1 = yes), aids (1 = yes).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Age = 60 years, History of myocardial infarction (1 = yes) = 0, Congestive heart failure (1 = yes) = 0, Peripheral artery disease (1 = yes) = 0, Stroke or TIA (1 = yes) = 0, Dementia (1 = yes) = 0, Chronic pulmonary disease (1 = yes) = 0, Connective tissue disease (1 = yes) = 0, Peptic ulcer disease (1 = yes) = 0, Liver disease (0 none, 1 mild, 2 moderate/severe) = 0, Diabetes (0 none, 1 uncomplicated, 2 end-organ damage) = 0, Hemiplegia (1 = yes) = 0, Moderate/severe CKD (1 = yes) = 0, Solid tumor (0 none, 1 localized, 2 metastatic) = 0, Leukemia (1 = yes) = 0, Lymphoma (1 = yes) = 0, AIDS (1 = yes) = 0 the result is 2.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
