Postoperative deep vein thrombosis: identifying high-risk patients
British Medical Journal
|August 2, 1980
Summary
This study validates a predictive index for deep vein thrombosis (DVT) risk. The index accurately identifies high-risk patients, enabling more rational use of prophylaxis.
Area of Science:
- Medical research
- Clinical diagnostics
- Thrombosis
Background:
- Deep vein thrombosis (DVT) is a significant postoperative complication.
- Accurate risk prediction is crucial for effective prophylaxis.
Purpose of the Study:
- To validate a predictive index for identifying patients at risk of developing deep vein thrombosis.
- To assess the index's accuracy in a prospective study.
Main Methods:
- Prospective study design.
- Utilized a predictive index based on five variables: euglobulin lysis time, serum fibrin-related antigen, age, overweight percentage, and varicose veins.
Main Results:
- The index correctly identified 90% of patients at risk.
- The index had a low false-positive rate, incorrectly identifying 7 out of 52 patients.
Conclusions:
- The validated predictive index can identify high-risk patients preoperatively.
- This allows for more rational and targeted use of DVT prophylaxis.
