    New Calculated Decisions!

    As any physician knows, making decisions around patient care are not always black and white, and every decision has potential risks and benefits, whether it's ordering a screening test, initiating medical treatment, or recommending an elective operation.

    MDCalc's tools help you make these calculated decisions based on the best evidence, sometimes quite literally by calculating your patient's risk of heart disease, or likelihood of PE diagnosis, or survival. We've teamed up with EB Medicine to create expanded versions of our calculator reviews to help doctors make these decisions. Each section corresponds to the one of the MDCalc content tabs you're already familiar with, expanded into a long-form, readable format.

    EB Medicine provides practical and reliable answers, in a concise and easy-to-use format, to inform and improve your clinical decision making when it matters most. Screening calculators paired with peer-reviewed research on clinical topics, Calculated Decisions provides you with the information you need.

    Check out our list of current and upcoming Calculated Decisions, available free of charge for registered MDCalc users:
