Conditions
Brief summary
Vascular ultrasounds are a limited resource and not always available in Emergency Departments. Similarly, current clinical decision rules are either too subjective or burdensome to result in high compliance in the Emergency Department. This study aims to derive a simple clinical decision rule to safely exclude the diagnosis of DVT and reduce the amount of vascular ultrasounds performed in the ED.
Interventions
A retrospective cohort study (up to 4 years of Emergency Department (ED) presentations) reviewing historical risk factors, examination findings and d dimer levels and the ability to combine these into a simple score to accurately exclude the diagnosis of deep vein thrombosis (DVT)
Data will be reviewed from electronic medical records for patients presenting to the Emergency Departments at Royal North Shore Hospital and Hornsby Kuringgai Hospital between 1 January 2021 and 31 December 2024. Reco
A retrospective cohort study (up to 4 years of Emergency Department (ED) presentations) reviewing historical risk factors, examination findings and d dimer levels and the ability to combine these into a simple score to accurately exclude the diagnosis of deep vein thrombosis (DVT) Data will be reviewed from electronic medical records for patients presenting to the Emergency Departments at Royal North Shore Hospital and Hornsby Kuringgai Hospital between 1 January 2021 and 31 December 2024. Records will be assessed during a single presentation and it will be noted if the patient has re-presented within the following 14 days. A review of medical records for history and examination findings as well as investigation results of D dimer blood results and Vascular US imaging reports will be collected. The novel algorithm will be developed using statistical analysis (both regression analysis and bootstrapping) to determine a combination of risk factors that are sufficiently sensitive to exclude DVT.
