Calculators

10-Year ASCVD Risk Calculator

Estimates 10-years & lifetime risk of MI or stroke using pooled cohort equations. Helps guide primary prevention (e.g., statin initiation, tighter BP control, selective ASA use) and supports shared decision-making in at-risk adults.

eGFR Calculator

Estimates kidney function using the 2021 CKD-EPI equation (the ACC/AHA and KDIGO-recommended standard). More accurate across diverse populations than older MDRD/2009 formulas. Guides CKD staging, medication dosing, and referral decisions.

Wells Criteria for DVT

validated clinical tool for estimating pretest probability of DVT. Proven to improve diagnostic accuracy and reduce unnecessary imaging. Considered the standard approach to structured DVT assessment in primary care and emergency settings.

HEART Pathway for Early Discharge in Acute Chest Pain

Identifies emergency department patients with acute chest pain for early discharge.

Fracture Risk Assessment Tool (FRAX®)

The FRAX tool estimates a patient’s 10-year probability of major osteoporotic and hip fractures. It combines clinical risk factors with or without bone mineral density (BMD) to guide osteoporosis treatment decisions.

STOP-BANG Score for OSA

The STOP-BANG questionnaire is a simple screening tool for obstructive sleep apnea (OSA). It uses 8 yes/no questions: Snoring, Tiredness, Observed apneas, high blood Pressure, BMI >35, Age >50, Neck circumference >40 cm, and male Gender. The more “yes” answers, the higher the risk of OSA.

The Fibrosis-4 (FIB-4) Index

The Fibrosis-4 (FIB-4) Index is a non-invasive tool that uses routine blood tests to estimate the degree of liver fibrosis. It is especially useful in patients with chronic liver disease such as fatty liver (NAFLD/NASH), helping to identify those at risk of advanced fibrosis without the need for invasive procedures like liver biopsy.
