Key result
Following diagnostic algorithms correctly for suspected venous thromboembolism results in an extremely low risk (< 1%) of adverse events when VTE is ruled out.
Why the study?
Does a structured diagnostic strategy reduce adverse events in patients with suspected VTE?
Does a structured diagnostic strategy reduce adverse events in patients with suspected VTE?
A structured diagnostic strategy combining clinical probability scoring, D-dimer testing, and imaging is critical for safely ruling out VTE and minimizing the risk of recurrent VTE or death.

Supports structured VTE diagnostic algorithms in practice; leaves open randomized trials to confirm outcomes.
Hogg et al. (2012) conducted a review in Venous thromboembolism (suspected deep vein thrombosis or pulmonary embolism). Diagnostic strategy (clinical pretest probability assessment, D-dimer test, and imaging) vs. Incomplete diagnostic strategies was evaluated on Adverse events in patients in whom VTE has been ruled out. Following diagnostic algorithms correctly for suspected venous thromboembolism results in an extremely low risk (< 1%) of adverse events when VTE is ruled out.
