Implication
Empirical and Wells' assessments stratify DVT risk with similar accuracy despite poor agreement; leaves open preference pending prospective validation.
Structured PICO
Does empirical assessment compared to Wells' score provide similar accuracy and agreement in outpatients with suspected deep vein thrombosis?
P
Population
270 outpatients with suspected deep vein thrombosis (DVT) and a DVT prevalence of 21.1%, excluding those with a history of DVT or insufficient clinical information.
I
Intervention
Empirical assessment based on a predefined list of items that can be weighted individually.
C
Comparator
Wells' score (a formal score based on a number of items of fixed value).
O
Outcome
Accuracy and agreement of the two methods of clinical evaluation for suspected DVT.surrogate
Clinical probability assessment for suspected DVT can be performed with similar accuracy using either an empirical assessment or the Wells' score.
