Do you know your Clinical Prediction Rules

Clinical prediction rules (CPR) are a mathematical, statistical guideline which incorporates multiple predictors such as; medical signs, symptoms, and other findings, into a combination that will assist in predicting a diagnosis or treatment outcome. It is an evidence-based tool which can help diagnose certain conditions as well as help to select the most appropriate method of treatment for that diagnosis. It assists the Therapist in making the wisest decision on the appropriate treatment.
