[Current prophylaxis and treatment of venous thromboembolism in intensive care units of 41 tertiary hospitals of Zhejiang Province].

To investigate the prophylaxis and treatment of venous thromboembolism (VTE) in intensive care units (ICU) in Zhejiang Province. A cross-sectional questionnaire survey for ICUs doctors was conducted online at 41 tertiary hospitals in Zhejiang Province, which included basic information of ICUs, VTE-related installations, knowledge and monitoring system. The data collected from the questionnaire were summarized and analyzed. Most ICUs were comprehensive. The ratio of physicians to beds, ratio of nurses to beds, and the ratio of rehabilitation physicians to beds were 0.52∶1, 2.12∶1, and 0.03∶1 respectively. Thirty-five over 41 (85.4%) ICUs completed VTE risk assessment within 24 hours. Twenty-five over 35 ICUs (71.4%) chose the Caprini model to assess VTE risk. Ultrasound was preferred in 92.7% (38/41) of ICUs equipped ultrasound. Almost all (40/41, 97.6%) of hospitals possessed intermittent pneumatic compression (IPC) as mechanical prophylaxis. The ratio of IPC to bed was 0.22∶1. Low-molecular-weight heparin (92.7%, 38/41) was the initial treatment in ICUs. VTE prophylaxis system has been established in 92.7% (38/41)hospitals and 87.8% (36/41) ICUs,related personnel groups were set up in 75.6% (31/41) hospitals and 58.5% (24/41) ICUs including 68.3% (28/41) hospitals with multidisciplinary team. VTE prophylaxis system in different hospitals was heterogeneous. VTE risk assessment models in different ICUs were not identical. There were unmet clinical needs of VTE mechanical prophylaxis equipment. In conclusion, VTE screening, evaluation and prophylaxis protocols in ICUs still need to be standardized and improved.
