OBJECTIVES: To examine the effect of a community pharmacy based medication therapy management program (MTM) on patient outcomes over one year. METHODS: A one year, pre-post longitudinal study.  Patients served as their own controls.  Community pharmacists provided MTM services to the City of Toledo employees and their dependents with diabetes.  Employees were seen every 3 months at one of seven participating pharmacy sites.  Participants received a 3 month supply of medications at the cost of one co-pay as an incentive.  Data collected: quality of life scores (SF-36),  self-reported adherence (Modified Morisky scale of 1-5, 1 being always adherent and 5 being never adherent), number of sick days, and patient satisfaction with services (Likert scale of 1-5, 1 being highly unsatisfied and 5 being highly satisfied).  Data was analyzed using SPSS v 16.0 for one year using descriptive statistics and Friedman tests. RESULTS: One hundred one employees enrolled at baseline.  Patients had improved scores on physical functioning, role physical, bodily pain, and social functioning.  The physical component summary remained roughly the same.  Mental component scores decreased, but not significantly.  Self-reported adherence improved significantly from 3.83 to 2.68 (p<0.005) over 12 months.  There was a decrease in the use of sick days from 1.13 ± 5.32 at baseline to 0.09 ± 0.39(p=0.368) at the end of the study.  Patients who reported using sick days at baseline on average reported less use of sick days over one year.  Overall patient satisfaction significantly increased from 3.26 to 4.52 (p<0.001) over 12 months.  Experience with the pharmacist and experience with pharmacy services were the highest rated items. CONCLUSIONS: Improved quality of life and adherence can help increase productivity of employees and can help reduce costs for employers by reducing disease-related missed days of work.  Employers looking to save costs and improve productivity can utilize the services provided by pharmacists.
