Diagnostic accuracy of the Wells score versus duplex ultrasound for deep vein thrombosis in a Ghanaian cohort

Key Points

• This research aims to evaluate the diagnostic accuracy of the Wells score compared to duplex ultrasound for detecting deep vein thrombosis (DVT).
• Analyzed a cohort of suspected DVT patients in Ghana.
• Used the Wells score and duplex ultrasound for diagnosis.
• Examined the prevalence of DVT and associated clinical features.
• DVT prevalence in the cohort was 38.8%.
• Common symptoms included localized tenderness, calf swelling, and history of previous DVT.
• Reducing the Wells score cut-point to 1 improved sensitivity and accuracy.
