Pretest Probability Estimates: A Pitfall to the Clinical Utility of Evidence-based Medicine?
Academic Emergency Medicine, 2004Abstract Objectives: The Bayesian application of likelihood ratios has become incorporated into evidence‐based medicine (EBM). This approach uses clinicians' pretest estimates of disease along with the results of diagnostic tests to generate individualized posttest disease probabilities for a given patient.

Evaluation of the pretest probability of severe OSA in a bariatric population
Sleep and control of breathing, 2018Introduction: Preoperative screening of obstructive sleep apnea (OSA) is currently recommended in patients undergoing bariatric surgery (BS). Aims: To evaluate the prevalence of severe OSA among patients undergoing BS, and the diagnostic performance and the discriminative value of clinical parameters.

Value of assessment of pretest probability of deep-vein thrombosis in clinical management
The Lancet, 1997When ultrasonography is used to investigate deep-vein thrombosis, serial testing is recommended for those who test negative initially. Serial testing is inconvenient for patients and costly. We aimed to assess whether the calculation of pretest probability of deep-vein thrombosis, with a simple clinical model, could be used to improve the management of

A Bayesian network can estimate a numeric pretest probability of venous thromboembolism on the basis of values of clinical variables. We determine the accuracy with which a Bayesian network can identify patients with a low pretest probability of venous thromboembolism, defined as less than or equal to 2%.Using commercial software, we derived a ...

Pretest probability estimation in the evaluation of patients with possible deep vein thrombosis
The American Journal of Emergency Medicine, 2011An estimation of pretest probability is integral to the proper interpretation of a negative compression ultrasound in the diagnostic assessment of lower-extremity deep vein thrombosis. We sought to determine the rate, method, and predictors of pretest probability estimation in such patients.This cross-sectional study of outpatients was conducted in a ...

The objective of this current trial was to evaluate the rate of deep-vein thrombosis (DVT) in patients after low clinical risk stratification and to evaluate the value of D-dimer and different imaging techniques in the diagnostic algorithm. A total of 99 consecutive patients were included in this prospective trial.

Journal of the American Society of Echocardiography, 2016
Recommendations for testing in patients with low pretest probability of coronary artery disease differ in guidelines from no testing at all to different tests. The aim of this study was to assess the value of exercise echocardiography (ExE) to define outcome in this population.A retrospective analysis was conducted of 1,436 patients with low pretest ...

Prior probability (the pretest best guess) affects predictive values of diagnostic tests
Veterinary Clinical Pathology, 2011Abstract: Authors who publish evaluations of dichotomous (yes/no) diagnostic tests often include the predictive values of their test at a single prior probability (eg, the prevalence of the target disease within the evaluation data set). The objectives of this technical note are to demonstrate why single‐probability predictive values are misleading ...
