Member satisfaction with health care delivered in managed care organizations (MCOs) can have profound effects on the health outcomes for patients. In the U.S., health employer data information sets (HEDIS) guidelines list satisfaction with pharmacy services as an indicator of quality of care. Pharmacy services are an important component of health care benefits, and are frequently listed as a patient dissatisfier. Dissatisfaction with pharmaceutical care can lead to noncompliance, nonpersistence, and delay necessary therapies. Increasingly, report card type measurements are included as a segment of MCO National Committee for Quality Assurance (NCQA) accreditation evaluations. OBJECTIVES: The study purpose was to assess satisfaction with pharmacy services in two populations of a large MCO as a NCQA quality improvement/preventive health activity project. METHODS: Patients using pharmaceutical services in varying practice sites were surveyed via a mailed questionnaire to determine satisfaction with MCO pharmacy services. Statistical analyses included use of analysis of variance (ANOVA) with Tukey HSD follow-up tests, and chi-square comparisons. RESULTS: A 68% percent response rate was reached with both surveys. In two U.S. metropolitan areas, satisfaction with pharmacy services exceeded 80% in a sample of 2,500 patients with no gender or age differences in levels of satisfaction. However, satisfaction with specific types of pharmacies (independent community, food market, chain community) was significantly different (p<0.01) as analyzed via ANOVA for specific and general components of pharmaceutical care delivery. Tukey HSD follow up tests indicated a significantly lower level of satisfaction in chain community pharmacies when compared with the two other pharmacy types. A Pearson’s correlation noted a directly positive relationship between self-assessed health status and satisfaction with pharmacy services (r=0.154, p<0.001). CONCLUSIONS: Satisfaction with pharmacy services can be high in general in MCOs, but it is important to further study levels of satisfaction based on pharmacy type and patient health status.
