Abstract
BACKGROUND The 2009 China Intensive Care Units (ICU) prevention guidelines lack venous thromboembolism (VTE) risk assessment. This survey was conducted to assess the risk of VTE, develop and establish a diagnosis, and provide prevention and treatment guidelines for ICU VTE. MATERIAL AND METHODS A cross-sectional questionnaire survey of ICU doctors ICUs was conducted online in the tertiary and secondary hospitals of Zhejiang province in China. The questionnaire included VTE-related hospital hardware information, VTE awareness, knowledge, and monitoring system. RESULTS The risk assessment rates at the time of admission and changed disease condition were 67.7% and 60.4%, respectively. D-dimer and ultrasound were commonly used for VTE screening. Heparin is preferred for short-term intravenous anticoagulant therapy, and warfarin is preferred for long-term therapy. We found that 23.53% of the ICUs have bedside ultrasound and staff for ultrasound examination, and 59.4% of the hospitals are equipped with VTE monitoring information systems. The VTE early identification specification is the key to whether the VTE assessment is performed after the patient enters the ICU. CONCLUSIONS The survey assessed the VTE risk and key VTE management elements. However, high heterogeneities were detected in the assessment. The ICU doctors have relatively limited awareness of VTE. Thus, there is an urgent need to update and standardize the ICU VTE guidelines for the prevention and treatment of VTE in China.
