Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

470
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Venous Thrombosis III: Interprofessional Care

482
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

760
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Area of Science:

  • Medical Diagnostics
  • Clinical Pathology
  • Cardiovascular Medicine

Background:

  • Pulmonary embolism (PE) diagnosis relies on accurate D-dimer testing and imaging.
  • Guideline adherence in diagnostic test ordering is crucial for clinical utility.
  • Dubbo Health Service sought to evaluate D-dimer assay utilization for PE diagnosis.

Purpose of the Study:

  • To investigate D-dimer assay ordering patterns for pulmonary embolism (PE) diagnosis.
  • To assess the clinical usefulness of D-dimer testing at Dubbo Health Service.
  • To compare ordering patterns with established diagnostic guidelines.

Main Methods:

  • Retrospective audit of 245 patients undergoing D-dimer testing at Dubbo Health Service (Jan-Dec 2024).
  • Categorization of D-dimer and CTPA ordering sequences against guideline recommendations.
  • Analysis of test utilization within the clinical context.

Main Results:

  • 79.2% of investigations followed guideline-recommended D-dimer and CTPA sequences.
  • The diagnostic yield of CTPA after D-dimer testing was 4.9%.
  • Discordant pathways included positive D-dimer without CTPA, or CTPA despite negative D-dimer.

Conclusions:

  • D-dimer ordering patterns showed variable alignment with guideline pathways, potentially limiting clinical usefulness.
  • Increasing utilization of D-dimer testing and CTPA aligns with broader trends.
  • Enhanced documentation of pre-test probability and targeted education can improve diagnostic workflow integration.
