OBJECTIVES: To explore the preventive effect of the FOCUS-PDCA management model on deep vein thrombosis (DVT) in elderly orthopedic patients after surgery. METHODS: A total of 229 elderly patients who underwent orthopedic surgery in our hospital between January 2021 and December 2023 were divided into two groups: the control group (n=104) and the intervention group (n=125), based on their admission order. The control group received routine intervention, while the intervention group was treated with the FOCUS-PDCA model. Coagulation function, DVT risk symptoms, incidence of DVT, intervention quality, and patient satisfaction were compared between the two groups. RESULTS: After the intervention, the PT and APTT/s levels in the intervention group were significantly better than those in the control group, while the Fibrinogen (FIB) level was significantly lower (P <
0.05). The DVT risk symptoms and incidence of DVT were also lower in the intervention group (P <
0.05). Additionally, the intervention quality and patient satisfaction were higher in the intervention group compared to the control group (P <
0.05). CONCLUSIONS: The FOCUS-PDCA management model improves coagulation function and reduces the incidence of deep vein thrombosis in elderly orthopedic patients after surgery.
