OBJECTIVES : To adapt a pharmaceutical care satisfaction instrument and pilot test it to measure patient satisfaction with Medication Therapy Management (MTM) services. METHODS A questionnaire was mailed to Medicare Part D beneficiaries who received face-to-face MTM services in a retail pharmacy in a southern state. The questionnaire consisted 23 questions addressing patients' perceptions, experience, and satisfaction related to MTM services. Information regarding patients' satisfaction was gathered using an instrument developed by Gourley et al. (2001) with a few modifications to make it applicable to MTM service encounter. We assessed the content validity and pre-tested the questionnaire to determine the time needed to complete and to ensure item clarity. Factor analysis using the principal component method with varimax rotation and reliability analysis using Cronbach's alpha was conducted. RESULTS Of the 403 successfully mailed surveys; we received 122 useable surveys yielding a response rate of 30.27%. Sample comprised 55% females, 68% whites. Over 80% of the study participants took 5-16 unique medications daily. Factor analysis using a 0.55 cut-off for factor loading yielded four factors that accounted for 64.4% of the variance. Reliability assessment resulted in Cronbach's alpha value of 0.941 for the entire scale, 0.904 for factor 1 (Managing Medication Therapy), 0.917 for factor 2 (Patient Education), 0.910 for factor 3 (Overall Satisfaction), and 0.841 for factor 4 (Pharmacist-Patient Relationship). The overall mean score was found to be 4.5/5 indicating that the participants were satisfied with the MTM services they received. CONCLUSIONS The adapted questionnaire consisted of four subscales similar to subscales found in other pharmacy satisfaction surveys. The instrument appears to be useful in measuring patient satisfaction with MTM services received in a pharmacy. Low sample size, extrapolation of results to other states and settings, and recall bias are the notable limitations associated with this study.
