Abstract:

We define Clinician Numeracy (CN) as "the ability to use numbers and numeric concepts in the context of taking care of patients." CN includes 3 domains: primary numeric skills, applied numeracy, and interpretive numeracy. Some key interpretive skills - understanding the difference between relative and absolute risk and understanding how prevalence of a disease influences the value of a test - have been shown to be important for clinical judgment. A modern theory of medical decision making with a growing body of support (fuzzy trace theory) asserts that medical decisions are most often based on gist-based intuition or "simple, bottom-line representations of the meaning of information or experience." We present a conceptual model that utilizes this theory to show how CN might be related to clinician decision making and health outcomes via the 'risk gist.'
