MDCalc is a clinical decision support platform founded in 2005 by practising emergency-medicine physicians. The company provides over 900 evidence-based calculators, risk scores and clinical tools covering more than 50 medical specialties and upwards of 200 patient conditions. It is used by millions of clinicians worldwide and reaches users in over 200 countries and territories; within the United States, more than 80% of clinicians have adopted the platform.
The company operates at the intersection of healthcare and medical education, partnering with research teams, medical societies and clinical-tool creators to curate resources that prioritise evidence quality, clinical utility and patient-centred practice. Its catalogue spans specialties from cardiology to emergency medicine, offering point-of-care guidance grounded in peer-reviewed literature.
MDCalc's origins as a physician-built tool inform its approach to product development: content is evaluated for its ability to influence clinical decisions and improve patient outcomes. The platform serves as a reference point for clinicians seeking to integrate evidence-based medicine into everyday practice.
