Abstract
Objectives: To determine whether patients who received Medication Therapy Management (MTM) from community pharmacists using a brief scale to measure Therapeutic Alliance (i.e., MTM + TA) would show better medication adherence than patients who received MTM without use of the TA scale (MTM only). Design: Quasi-experimental, using a direct intervention group (MTM + TA) and a comparison group of randomly selected claims records from patients who received only the MTM service (MTM only). We used a doubly robust propensity score approach to estimate the average effect of therapeutic alliance on medication adherence. The analysis was limited to the following broad medication categories: antihypertensives, antidiabetic agents, and antihyperlipidemics. Setting: The direct intervention group included patients receiving MTM services from pharmacists in a community pharmacy chain setting. Participants: After matching with claims data, the direct intervention group was n=117, with an average age of 76.4. The comparison group was n=146, with an average age of 76.2. Intervention: Administration of two brief scales designed to measure general health outcomes and TA within the context of MTM (with focus on TA scale administration). Main Outcome Measures Proportion of Days Covered (PDC) and PDC80. Results: Using the therapeutic alliance scales in the context of community pharmacist-provided MTM was associated with a 3.1 percentage point increase in patients' overall PDC (p
