Implementation and Evaluation of Clinical Decision Support for Apixaban Dosing in a Community Teaching Hospital.

Abstract

Objectives: This study aimed to describe and evaluate the transition from a specialty service-based prospective order approval system to a computerized clinical decision support (CCDS) tool for apixaban dosing at a community teaching hospital. The primary objective was to assess the impact of the transition on the appropriateness of apixaban prescribing.

Methods: A CCDS tool for apixaban dosing was developed and implemented using interprofessional collaboration. A retrospective chart review was conducted for apixaban orders placed before (preimplementation) and after (postimplementation) the CCDS transition. The primary outcome was the percent change in inappropriate apixaban orders, with secondary outcomes exploring percent change of apixaban orders with inappropriate dosing in different patient groups and indications per package insert.

Results: Fifty orders were assessed in both arms, with 8% of orders preimplementation and 10% postimplementation deemed inappropriate. After accounting for questionable orders, overall appropriateness of prescribing was 88% preimplementation and 84% postimplementation ( P = 0.7). Challenges with implementation of CCDS included working with available information technology resources and facilitating acceptance of a new ordering process.

Conclusions: The implementation of a CCDS tool for apixaban dosing at a community teaching hospital demonstrated comparable rates of appropriateness to the previous specialty service-based approval process. While the transition streamlined resources and improved efficiency, ongoing efforts are needed to address specific dosing challenges. Future research should explore the sustainability and generalizability of CCDS tools in diverse healthcare settings.
