Abstract´╝Ü Objective:To investigate the prevention and treatment status of venous thromboembolism (VTE) of pregnant women in general hospitals and specialized hospitals in China.Methods:This study was a cross-sectional survey about VTE prevention and treatment in 112 hospitals across China from January 1st to December 31st, 2019, including general information, resource accessibility, hospital system and strategy. According to the characteristics, the hospitals were divided into general hospital group (70 hospitals) and specialized hospital group (42 hospitals). The basic information, VTE diagnosis and treatment resources, prevention systems and the preference of the VTE risk assessment form of the two groups were compared. Logistic regression was used to analyze the proportion of VTE incidence and related factors in the two groups of hospitals.Results:(1) The median annual delivery volume of the general hospital group was significantly lower than that of the specialized hospital group (3 428 vs 9 969 cases, P<0.01), the diagnostic accessibility of CT pulmonary angiography (CTPA) was significantly higher than that of the specialized hospital [92.9% (65/70) vs 59.5% (25/42), P<0.01], and the proportion of obstetric VTE risk assessment was significantly higher than that of the specialized hospital group [85.7% (60/70) vs 66.7% (28/42), P=0.017]. (2) Among the 88 hospitals using the VTE risk assessment sheet, the utilization rate of the evaluation sheet recommended by the obstetric VTE guideline in specialized hospitals (78.6%, 22/28) was higher than that of general hospitals (48.3%, 29/60), and the difference was statistically significant ( P=0.007). (3) The proportion of VTE incidence in general hospital group was 0.126% (360/286 517), and the proportion of VTE incidence in specialized hospital group was 0.032% (154/484 111). Logistic regression analysis showed that the OR value of the specialized hospital group was 0.253 (95% CI: 0.209-0.305) and the difference was statistically significant ( P<0.01) compared with the general hospital group. After adjusting the hospital level, B-ultrasonography and CTPA accessibility, whether to establish a risk assessment and obstetric VTE system, the proportion of VTE incidence in specialized hospitals was still lower than that in general hospitals ( OR=0.307, 95% CI: 0.251-0.376, P<0.01). Conclusions:General hospitals have higher access to resources for diagnosing VTE than specialized hospitals, and the VTE evaluation system is better implemented. The utilization rate of the obstetric VTE guidelines in specialized hospitals is higher than that of general hospitals.
