MDCalc

MDCalc is entering its 20th year. What began as a project born of necessity–to ease cognitive overload in real-time medicine–has become one of the most widely used and trusted Clinical Decision Support platforms in the world.

Today, more than 80% of U.S. clinicians, and millions globally, use MDCalc to guide better care decisions at the bedside.

With nearly 900 rigorously vetted evidence-based guidelines, scoring systems, medical calculators, and risk assessments across 50+ specialty areas, MDCalc is built to meet the demands of real-world care, elevating and reinforcing clinical judgment.

As we enter our third decade, our goal remains simple: to bring clarity to clinical complexity. Every tool is designed to reinforce–not replace–clinical judgment. Every update reflects our core values: safety, simplicity, and trust.
