Medical Calculators & Clinical Decision Rules
Deterministic clinical prediction rules, thromboembolic risk scores, and organ clearance equations. Every formula is backed by peer-reviewed validation studies and runs 100% in-browser with zero health data logging.
BMI & BSA Calculator
Body Mass Index & Body Surface Area Calculator
Clinical calculator for Body Mass Index (WHO/CDC) and Mosteller Body Surface Area.
CHA₂DS₂-VASc
CHA₂DS₂-VASc Score for Atrial Fibrillation Stroke Risk
Validated clinical risk score predicting annual thromboembolic stroke risk in non-valvular atrial fibrillation.
Wells Criteria for DVT
Wells Clinical Prediction Rule for Deep Vein Thrombosis
Validated diagnostic decision rule stratifying the pre-test probability of lower-extremity deep vein thrombosis.
CURB-65
CURB-65 Severity Score for Community-Acquired Pneumonia
Validated clinical prediction rule determining 30-day mortality and triage for community-acquired pneumonia.
eGFR (2021 CKD-EPI)
Estimated Glomerular Filtration Rate (2021 CKD-EPI Creatinine Equation)
Race-free equation recommended by NKF and ASN to estimate renal glomerular filtration rate from serum creatinine.
How Clinmetric Implements Clinical Decision Rules
Pre-Test Probability & Bayesian Principles
Tools such as the Wells Criteria for DVT calculate pre-test clinical probability before ordering diagnostic testing. When pre-test risk is unlikely, high-sensitivity D-dimer testing safely excludes thromboembolism without unnecessary compression ultrasound.
Auditable & Race-Free Equations
Our renal clearance calculator implements the 2021 race-free CKD-EPI equation recommended by the National Kidney Foundation and American Society of Nephrology, avoiding racial bias in estimating glomerular filtration rate.
