History and Physical Test Calculators

Calculators of the value of various history or physical findings

Purpose: To support the clinical decision making of a clinician by offering information regarding the likelihood of patients having a disease based on information gathered during a history and physical evaluation

Example: What is the likelihood of strep throat in a patient with tonsillar exudates? In a patient with low back pain, what symptoms are indicators of ankylosing spondylitis?

Detailed Description: The calculator gives users the probability of the disease based upon the results of clinical evaluation before doing additional testing. Users can choose one of several elements of the history and physical. They can also change the probability of disease based upon a clinical decision rule or gestalt. This allows users to tailor interpretation of the clinical circumstances to decide if additional testing is worthwhile.
