Holism in health care, and specifically in pharmacy, are discussed, along with the views of patients and professionals concerning expanded pharmacists' roles, and the effects of those roles. In describing holism in health care, attention is directed to holism and several concepts: wellness versus the absence of disease; prevention; mind, body, and spirit; environments; balance versus imbalance; altered practitioner/patient roles; and therapy. Twenty-five types of tasks completed by pharmacists and the percentage of time spent on each are indicated. In addition, duties that could be handled by other personnel are identified. Studies demonstrate that the opportunities for expanded roles for pharmacists exist, and that both the consumer and professional populations are willing to allow their inclusion into traditional medical practices. The incorporation of these expanded roles may be seen as promoting holistic health care. Based on a literature review, a list of expanded pharmacists' roles that were proposed by pharmacy authorities is provided. The tasks are grouped under the following categories: clinical services; guidance/counseling functions; education functions; education, screening, and monitoring functions; pharmacist/doctor relationship; laboratory services; and socioeconomic functions.
