Objective To investigate the implementation of physical preventive measures for deep vein thrombosis （DVT） by orthopedic nurses, and to provide theoretical basis for better implementation of DVT physical preventive measures.Methods An electronic questionnaire was used to investigate the implementation of DVT physical preventive measures among 286 orthopedic nurses from 60 hospitals at secondary and above levels in 20 provinces and cities nationwide.Results The total score of nurses implementing DVT physical preventive measures was 13.5 （11,15）points, and the scoring rate was 65.84%.The levels of the hospitals, whether the ward had DVT prevention norms, whether to establish a DVT prevention group, whether the nurses had received DVT knowledge training, the places where DVT knowledge training was conducted, and the technical titles of orthopedic nurses , were associated with varied DVT physical preventive measures scores by the nurses（P＜0.05，P＜0.01）.About 90% of the hospitals were equipped with one or more physical prevention devices.Physical precautions before and after surgery were still dominated by patient activities, while the use of physical prevention devices was relatively rare.The use of physical prevention devices was mainly twice a day, 30 minutes each time. Conclusion DVT physical prevention devices are commonly available in orthopedic department, but their clinical implementation needs to be strengthened and standardized.Nursing managers should strengthen the training of DVT prevention knowledge for nurses, in an effort to improve their prevention skills and promote the implementation of the preventive measures.
