415 Discrepancy Between Gestalt and Subjective Wells in Workup of Pulmonary Embolism

Clinicians frequently use either their experience (or gestalt) to determine the pretest probability of pulmonary embolism (PE), or use a scoring system such as the Wells score. Research suggests that gestalt approach is equally safe as the Wells score algorithm in diagnosing PE. It also shows that that the subjective component of the Wells score drives most of its predictive accuracy. How well the subjective component of the Wells score corresponds to the provider's pretest gestalt for PE is not clear.
