Clinical Decision Rules (CDRs)

Clinical Decision Rules (CDRs) are evidence-based tools used by healthcare providers to guide diagnosis and treatment decisions. They combine specific patient information—like symptoms, test results, or medical history—to help determine the likelihood of a particular condition. By standardizing assessments, CDRs improve accuracy, reduce unnecessary tests or treatments, and support consistent care. They are developed through research and are meant to assist, not replace, clinical judgment, ensuring patients receive appropriate and efficient care based on the best available evidence.
