Contributors to MDCalc
MDCalc’s Contributors author the content accompanying calcs, which provides guidance on When to Use, Pearls/Pitfalls, Why Use, Next Steps, and an Evidence Appraisal. Our Contributors tend to be academic physicians practicing clinically, typically earlier in their careers, who are passionate about EBM and interested in translating evidence into usable bedside tools.
Contributors who write content for three or more calcs or other reviews have the opportunity to be listed on this page, with an expected contribution of one calc per year thereafter to be considered an active contributor (see past contributors here).
We also consider fellows and senior residents going into academic medicine. Applications for Contributors are reviewed on a rolling basis. Contributors may also be invited to peer review other calculators in their specialty.
