Evidence-based medicine in otolaryngology, Part 3: everyday probabilities: diagnostic tests with binary results.

Journal Article (Journal Article)

Recent studies have demonstrated that the majority of physicians cannot accurately determine the predictive values of diagnostic tests. Physicians must understand the predictive probabilities associated with diagnostic testing in order to convey accurate information to patients, a key aspect of evidence-based practice. While sensitivity and specificity are widely understood, predictive values require a further understanding of conditional probabilities, pretest probabilities, and the prevalence of disease. Therefore, this third installment of the series "Evidence-Based Medicine in Otolaryngology" focuses on understanding the probabilities needed to accurately convey the results of dichotomous diagnostic tests in everyday practice.
