A Meta-Analysis: The Dvt Prevalence And Its Risk Factors Among Sci Patients

Deep vein thrombosis (DVT), as one of the most common secondary complications of spinal cord injury (SCI), is a potentially catastrophic condition for patients with SCI. We carried out the current meta-analysis to estimate the DVT prevalence and its relationship with the gender and American Spinal Injury Association (ASIA) grades of SCI patients. Relevant studies published before November 3, 2016, were retrieved from PubMed, EMBASE and Web of Science databases. The pooled DVT event rate and 95% confidence interval (CI) among SCI patients was generated, and the odds ratios (ORs) with corresponding 95% CIs of the gender and ASIA grades of SCI patients were also yielded. The overall DVT event rate was 14.8% among SCI patients, 25.9% among those in Asia, 12.1% among those in non-Asia, 19.7% among those from rehabilitation institutes and 9.9% among those from hospitals. With respect to the risk factors of DVT in SCI patients, no significant association between the DVT prevalence and the gender or the ASIA grades of SCI patients was observed. In conclusion, our meta-analysis reveals that the DVT prevalence rate among SCI patients in Asia or rehabilitation institutes is higher than that among those in non-Asia or hospitals, and neither the gender or the ASIA grades of SCI patients was risk factor for DVT prevalence.
