Objective To summarize the best evidence for prevention of deep vein thrombosis (DVT) in lower limbs of patients with spinal cord injury (SCI), and provide a basis for medical staff to develop evidence-based prevention and management measures for DVT in the lower limbs of patients with SCI. Methods UpToDate, BMJ Best Practice, Guidelines International Network, National Institute for Health and Clinical Excellence, Registered Nurses’ Association of Ontario, National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, New Zealand Guidelines Group, JBI evidence-based healthcare center database, Web of Science, Embase, Cochrane Library, CINAHL, Medlive, China guidelines network, SinoMed, China National Knowledge Infrastructure, and Wanfang were systematically searched. Evidence related to the prevention of DVT in lower limbs of patients with SCI has been collected. The search period was from January 1, 2019 to June 30, 2024, and the literature was screened, quality evaluated, evidence extracted, and summarized. Results Finally, 22 articles were included, including 3 guidelines, 2 clinical decision-making articles, 4 best practices articles, 7 evidence summaries, 4 expert consensus articles, and 2 systematic reviews. A total of 32 pieces of evidence were ultimately formed in six aspects of risk assessment, diagnosis and screening, prevention principle, drug prevention, mechanical prevention, and health education. Conclusions There is a lot of evidence involved in the prevention of DVT in lower limbs of patients with SCI. In the clinical implementation process, medical staff can carefully choose prevention plans based on the patients’ clinical condition to reduce the incidence of DVT in patients with SCI during hospitalization.
