RESUMO
Patients with critical illness are at the high risk of venous thromboembolism (VTE), and the older the patient, the higher the incidence of VTE. Despite its poor prognosis, VTE is preventable. At present, although there are many consensus or guidelines on the prevention of VTE at home and abroad, there is still a lack of consensus or guidelines for the prevention of VTE in elderly patients with critical illness. In order to standardize the prevention of VTE in elderly patients with critical illness in China, Expert consensus on the prevention of venous thromboembolism for elderly patients with critical illness in China (2023) was developed by Critical Care Medicine Division of Chinese Geriatric Society and Zhejiang Provincial Clinical Research Center for Critical Care Medicine. Members of the working group consulted relevant domestic and foreign guidelines, integrated evidence-based medical evidence and clinical experience, formed the draft consensus, submitted it to the expert group for discussion for many times, revised it for many times, and finally sent it to the expert group in the form of electronic questionnaire, and the expert gave a comprehensive score according to the theoretical basis, scientific nature and feasibility of the consensus items. The recommendation strength of each item was determined, and 21 recommendations were finally formed to provide reference for the prevention of VTE in elderly patients with critical illness.
