Key result
Medical service claims diagnostic codes demonstrated a sensitivity of 87% (95% CI 83-90) for DVT and 78% (95% CI 64-88) for PE within a 60-day window of the reference diagnosis.
Why the study?
Are medical claims database diagnostic codes sensitive for identifying deep vein thrombosis and pulmonary embolism?
Observational (n=355)
Are medical claims database diagnostic codes sensitive for identifying deep vein thrombosis and pulmonary embolism?
Effect estimate: Sensitivity 87% (95% CI 83-90)
Medical claims diagnostic codes demonstrate acceptable sensitivity for identifying DVT and PE when a 60-day window is applied, supporting their utility in epidemiological research.

Claims data codes may aid VTE research in RAMQ; leaves open validation needs before broader use.
Tagalakis et al. (2010) conducted an observational in Deep vein thrombosis (DVT) and pulmonary embolism (PE) (n=355). Medical service claims diagnostic codes vs. Objective clinical diagnosis (VETO study reference standard) was evaluated on Sensitivity of diagnostic codes for DVT and PE (Sensitivity 87%, 95% CI 83-90). Medical service claims diagnostic codes demonstrated a sensitivity of 87% (95% CI 83-90) for DVT and 78% (95% CI 64-88) for PE within a 60-day window of the reference diagnosis.
