Objective  To explore the effect of PDSA circulation in the prevention and management of venous thromboembolism (VTE) in hospitalized patients.

  Methods  A total of 61 136 hospitalized patients from January to December 2019 were selected as control group, and 55 118 hospitalized patients from January to December 2020 were selected as observation group. The control group was treated with conventional management measures, while the observation group was treated with PDSA circulation management mode. Implementation rate of preventive measures for VTE, implementation rate of preventive measures for cases with moderate to high risk of VTE and the incidence rate of VTE were compared between the two groups.

  Results  After the implementation of PDSA circulation management mode, the implementation rate of preventive measures for VTE increased from 42.26% to 76.32%, the implementation rate of physical preventive measures for cases with moderate to high risk increased from 38.24% to 70.26%, and the incidence rate of VTE decreased significantly from 4.04‰ to 2.99‰ (P < 0.05).

  Conclusion  PDSA circulation management standardizes each process of prevention and control for VTE, increases the implementation rate of preventive measures, deepens the connotation of prevention and control qualities, reduces the incidence of VTE, and ensures the safety of patients.
