RESUMO
OBJECTIVES: To (1) provide medication therapy management (MTM) services to patients, (2) measure the clinical effects associated with the provision of MTM services, (3) measure the percent of patients achieving Healthcare Effectiveness Data and Information Set (HEDIS) goals for hypertension and hyperlipidemia in the MTM services intervention group in relationship to a comparison group who did not receive MTM services, and (4) compare patients' total health expenditures for the year before and after receiving MTM services. DESIGN: Prospective study. SETTING: Six ambulatory clinics in Minnesota from August 1, 2001, to July 31, 2002. PATIENTS: 285 intervention group patients with at least 1 of 12 medical conditions using prestudy health claims; 126 comparison group patients with hypertension and 126 patients with hyperlipidemia were selected among 9 clinics without MTM services for HEDIS analysis. INTERVENTION: MTM services provided by pharmacists to BlueCross BlueShield health plan beneficiaries in collaboration with primary care providers. MAIN OUTCOME MEASURES: Drug therapy problems resolved; percentage of patients' goals of therapy achieved and meeting HEDIS measures for hypertension and hypercholesterolemia. Total health expenditures per person were measured for a 1-year period before and after enrolling patients in MTM services. RESULTS: 637 drug therapy problems were resolved among 285 intervention patients, and the percentage of patients' goals of therapy achieved increased from 76% to 90%. HEDIS measures improved in the intervention group compared with the comparison group for hypertension (71% versus 59%) and cholesterol management (52% versus 30%). Total health expenditures decreased from $11,965 to $8,197 per person (n = 186, P < 0.0001). The reduction in total annual health expenditures exceeded the cost of providing MTM services by more than 12 to 1. CONCLUSION: Patients receiving face-to-face MTM services provided by pharmacists in collaboration with prescribers experienced improved clinical outcomes and lower total health expenditures. Clinical outcomes of MTM services have chronic care improvement and value-based purchasing implications, and economic outcomes support inclusion of MTM services in health plan design.

BACKGROUND: Collaboration between physicians and pharmacists is one approach to address drug-related morbidity and achieve therapeutic goals. A collaborative practice of pharmaceutical care has been used in the Fairview Clinics System of Minneapolis-St Paul since 1999. METHODS: The quality of therapeutic determinations made by pharmacists within this collaborative practice of pharmaceutical care was studied by a 12-member panel of physicians and pharmacists who used randomly selected patient records. This was a quality improvement and care process validation component of a study evaluating the effects of drug therapy management in patients receiving prepaid medical assistance. An implicit review process was used to evaluate the clinical credibility of therapeutic determinations made by pharmaceutical care practitioners. RESULTS: A total of 5780 drug therapy problems were resolved for 2524 patients receiving pharmaceutical care. The rate of therapeutic goals achieved increased from 74% at the time of patients' initial pharmaceutical care encounters to 89% at patients' latest encounters. In this quality assessment analysis panel members performed a total of 4779 evaluations of clinical decisions. Panelists indicated agreement with the evaluations in 94.2% of cases, expressed a neutral opinion in 3.6% of cases, and disagreed in 2.2% of cases. Intraclass correlation coefficients ranged from 0.73 to 0.85. CONCLUSIONS: The decisions made by pharmaceutical care practitioners working in collaboration with physicians to provide drug therapy management services are clinically credible based on the evaluations and comments of a peer review panel. This study provides information on the quality of care provided by pharmacists when collaborating with physicians to provide drug therapy management services.
