A mixed methods evaluation of the implementation of pharmacy services within a team-based at-home care program

Abstract

Background: Sub-optimal medication use results in significant avoidable morbidity, mortality, and costs. Programs, such as comprehensive medication management (CMM), can help to optimize medication use, improve outcomes, and reduce costs. However, implementing programs like CMM can be challenging and differences in how CMM has been implemented may be responsible for observed heterogeneity in the outcomes associated with CMM.

Objective(s): Describe the implementation strategies utilized in implementing CMM telephonically within a team-based at-home care program and evaluate the implementation process.

Methods: The implementation of CMM was facilitated using various implementation strategies including: develop educational material and conduct training, change record system, audit and feedback, learning collaborative, quality monitoring, readiness assessment, and implementation team formation. The impact of these strategies as well as pharmacist and team member perspectives on the implementation of CMM were examined using mixed methods and guided by Proctor's conceptual model for implementation.

Results: The pharmacists felt that most of the implementation strategies used to facilitate consistent delivery of CMM were useful, but were unable to successfully implement all of them. Despite this, significant increases in fidelity to steps of the patient care process was achieved. The pharmacists felt that CMM was acceptable, appropriate for patient population, and feasible, but barriers (e.g., the telephonic and remote nature of the practice, the evolving nature of the program, and the difficulty in coordinating care between the patients primary care team and the care team affiliated with the program) affected the feasibility and organizational fit of CMM within this team-based, at-home care program. General pharmacy services, however, were seen as acceptable, appropriate, and feasible.

Conclusion: Deliberately designing and utilizing a variety of implementation strategies can facilitate the implementation of CMM and significantly increase fidelity to the patient care process. To improve feasibility and organizational fit of CMM, additional barriers and challenges need to be addressed.
