Standardized direct oral anticoagulants prescription for treatment of acute venous thromboembolism in the emergency department: A quality improvement initiative

Introduction: Direct oral anticoagulants (DOACs) are commonly used for the treatment and prevention of venous thromboembolism (VTE). However, prescription errors with DOACs can lead to patient dissatisfaction and harm. This study aimed to evaluate the impact of a standardized prescription for DOACs for VTE on prescription appropriateness.

Materials and methods: The study included patients discharged from the Emergency Department (ED) with a DOAC prescription for an acute VTE. A standardized prescription tool was developed and implemented, and patients were divided into pre- and post-intervention groups. The appropriateness of prescriptions was assessed using the Medication Appropriateness Index (MAI).

Results: A total of 161 patients with VTE were included in the study. The post-intervention group showed a significant increase in prescriptions with an MAI rating of "appropriate" and a decrease in ratings of "inappropriate." Improvements were observed in loading dose duration, maintenance dose frequency and duration, and inclusion of necessary drug coverage codes.

Conclusion: The implementation of a standardized prescription for DOACs in the management of VTE in the ED significantly improved medication appropriateness and reduced inappropriate prescriptions. Standardized prescriptions have the potential to enhance patient safety and optimize care by providing clear and uniform guidance to healthcare providers. Further research is needed to explore the effectiveness of medication prescription software systems in real-world clinical settings to improve prescribing practices.
