The Tennessee medication therapy management program: A hybrid type 2 effectiveness-implementation trial study protocol.

BACKGROUND

Pharmacist-led medication therapy management (MTM) programs are considered evidence-based and have clearly defined core components. Despite this, MTM programs are often implemented without fidelity due to notable implementation barriers, such as physician-pharmacist relationships and pharmacist access to patient medical records. To improve MTM implementation, the Tennessee Medicaid program developed a MTM intervention that incorporates implementation strategies to address some of the known barriers to implementation (e.g., formalizing pharmacist-physician relationships through collaborative practice agreements, ensuring pharmacists' access to medical records).

OBJECTIVES

The purpose of this hybrid type 2 effectiveness-implementation study is to (1) assess the effectiveness of the MTM pilot program in Tennessee (e.g., medication adherence, healthcare utilization, quality and cost of care) and (2) assess the implementation of the MTM pilot program (e.g., feasibility, appropriateness, acceptability, penetration).

METHODS

The Tennessee MTM pilot program is being assessed as a hybrid type 2 effectiveness-implementation study with a quasi-experimental design. A mixed methods approach (QUAN + QUAL) for the purpose of complementarity (e.g., answering related research questions). Data will include surveys, interviews, MTM platform encounter information, and medical and pharmacy claims. Initial analyses will include data between January 2018 and December 2019.

CONCLUSION

The study will further add to the evidence base of MTM interventions by testing an intervention that addresses known barriers to implementation and simultaneously collecting data on effectiveness and implementation to speed up MTM translation. The Tennessee MTM program is expected to serve as a guide to other states seeking to expand pharmacist-delivered clinical services to their Medicaid members, particularly those intending to incorporate MTM into programs seeking to improve primary care delivery. Further, by improving the implementation of MTM, the pilot program is expected to improve the reliability of MTM program benefits including healthcare quality and cost and patient outcomes.
