Brief Summary

The novel oral anticoagulants such as rivaroxaban, apixaban and dabigatran, specifically target either thrombin or factor Xa/IIa. These new agents are included as an option for prevention of thromboembolic disease or recurrent stroke in patients with non-valvular atrial fibrillation in guidelines. Although the benefits and risks of anticoagulation and antiplatelet therapy have been fully assessed, and reasonable anticoagulation and antiplatelet therapies have been formulated, the therapeutic effect still largely depends on the quality control during the treatment. Many patients discontinue anticoagulant therapy after discharge or after a period of treatment, and the risk of thrombosis increases. Because non-vitamin K antagonist oral anticoagulants (NOACs) does not need routine monitoring, patients tend to ignore the regular medication, thus affecting drug compliance. Because of the short half-life of NOACs, if patients do not take it regularly, not only can not achieve the effectiveness of anticoagulation, but also reduce the safety of medication. More and more researchers have realized that medication adherence plays a key role in medical management. In order to improve the efficacy and safety of NOACs and the compliance of patients with NOACs, the guidelines emphasize that supplementary measures can be taken, such as pharmacists participating in the network pharmacy database, attaching importance to the medication education of patients and their families, formulating a strict follow-up plan and professional outpatient follow-up.

Outcome Measures

Primary Outcomes (2)

  • Pharmacodynamic indicators

    Blood samples are divided into peak concentration and valley concentration. Peak concentration (Cmax) refers to the highest serum concentration after administration for at least one week in the study. Valley concentration (Cmin), the lowest concentration during administration, is usually obtained from the lowest concentration between the initial time of administration and the next time the drug is administered at a steady state (continuous medication for more than 1 weeks.).

    at least 1 week after drug administration

  • Medication adherence

    A compliance questionnaire was conducted to collect the compliance of the drug during treatment. According to the scores of MGLS, compliance was divided into three groups: A score of 0 indicated high compliance; a score of 1 or 2 illustrated intermediate compliance; and a score of 3 or 4 indicated low compliance.

    at least 1 week after drug administration

Study Arms (2)

case group

According to the scores of MGLS, compliance was divided into three groups: A score of 0 indicated high compliance; a score of 1 or 2 illustrated intermediate compliance; and a score of 3 or 4 indicated low compliance.

control group

According to the scores of MGLS, compliance was divided into three groups: A score of 0 indicated high compliance; a score of 1 or 2 illustrated intermediate compliance; and a score of 3 or 4 indicated low compliance.
