The Impact of MTM Model on the Efficacy and Safety of Anticoagulant Therapy in Postoperative Colorectal Cancer Patients

Anticoagulants are classified as high-risk medications, with their main adverse drug events (ADEs) being recurrent venous thromboembolism (VTE) and bleeding events.Postoperative colorectal cancer (CRC) patients exhibit a high probability of recurrent VTE and bleeding during anticoagulation therapy. In clinical practice, a considerable proportion of patients have experienced inappropriate prescribing of anticoagulants. Following a bleeding event, the decision on whether and when to initiate anticoagulation therapy requires individualized assessment by physicians and pharmacists based on each patient's specific condition. Moreover, over a quarter of patients prematurely discontinue anticoagulation therapy, which substantially increases their risk of VTE recurrence.Effective management of the use of anticoagulants holds significant importance. Pharmacist-led anticoagulation management can significantly improve the appropriateness of anticoagulant therapy and reduce total bleeding risk. However, the efficacy of various intervention approaches, such as medication reconciliation and medication monitoring, as well as the timing of intervention, has not been conclusively established. This study integrates multifaceted pharmacist interventions within the Medication Therapy Management (MTM) model, intervening at patient admission, during hospitalization, and post-discharge, to evaluate the impact of the MTM model on the efficacy and safety of anticoagulation therapy.

• CRC patients with VTE treated with an anticoagulant for at least 3 moths.

Exclusion criteria
