Review: graduated compression stockings prevent deep venous thrombosis in patients who are in hospital
QUESTION: Are graduated compression stockings effective and safe for preventing deep venous thrombosis (DVT) in hospital patients?
Randomised controlled trials were identified by the Cochrane Review Group on Peripheral Vascular Diseases, who searched EMBASE/Excerpta Medica and Medline and handsearched relevant medical journals and Index Medicus. Manufacturers were also contacted.
Trials were selected if stockings for the prevention of DVT were studied in any hospital patients, stockings were compared with no prophylaxis or another method of prophylaxis, and outcomes of DVT, pulmonary embolism (PE), or complications of stocking use were measured. DVT had to be identified by ultrasound, venogram, or isotope studies, and PE had to be identified by ventilation perfusion lung scan, pulmonary angiogram, or postmortem examination.
Data were extracted on study quality; patient age, sex, and risk category for DVT; type and …
