This does not imply that most decisions are wrong. Clinical prediction tools allow clinicians to make more precise estimates of the probability of disease presence, absence, or of a specific event occurring. This is similar to posing a question for a diagnostic test search, except the test we are evaluating is a clinical prediction tool. As usual, the best yield is through one of the NLM databases. Again, the TRIP database is a good place to start if you are short on time.
Several sites provide online, interactive, clinical prediction tools.
However, to critically evaluate these tools you must review the original report on the tool. If you have not already done so, this is a good point to stop and read more about literature searching. The outcome which the decision model predicts should be clinically relevant, and be clearly defined. Persons determining the outcome should be blinded to other clinical information and predictor values. Methods and reporting.
