4.1 Main findings
In this hospital-based point prevalence survey conducted across 113 hospitals in China, we found significant hospital-related variations in the incidence of thromboembolism in pregnancy. Hospital-related factors, including the preventive system and strategy employed, diagnosis and treatment availability, and patient education significantly affected the prevalence of DVT, PE, and maternal death due to VTE. Therefore, further efforts must focus on strengthening the existing preventive strategies, improving diagnosis and treatment availability, and promoting the level of patient education in order to reduce the VTE-related maternal mortality and mobility.
