The term "value-added" is widely used to describe business and professional services that complement a product or service or that differentiate it from competing products and services. The objective of this study was to determine compounding pharmacists' self-perceptions of the value-added services they provide. A web-based survey method was used. Respondents' perceptions of their most important value-added service frequently fell into one of two categories: (1) enhanced pharmacist contribution to developing and implementing patient therapeutic plans and (2) providing customized medications of high pharmaceutical quality. The results were consistent with a hybrid community clinical practice model for compounding pharmacists wherein personalization of the professional relationship is the value-added characteristic.
