Responsibilities or practice requirements of pharmacy interns at three levels of expertise are outlined, and guidelines for using the designations in supervision and instruction are presented. Recent trends in pharmacy internship and the methodology that was used to identify performance dimensions, responsibilities, and tasks are examined, along with suggested minimum standards for preceptors and for pharmacies acting as training sites. The beginning level internship duties are largely technical in nature, while the intermediate level internship duties are professional and are based on prerequisite knowledge about drug products. Advanced internship activities occur concurrently with or follow completion of courses in pharmacology, therapeutics, and prescription dispensing. The following dimensions of pharmacy practice are outlined: selecting drug products and ingredients, compounding prescriptions, dispensing prescriptions, monitoring and evaluating therapy, communicating with patients about legend drugs, communicating with patients on selection of drugs and supplies, communicating with health care professionals, maintaining professional and ethical standards, providing emergency pharmacy services, fulfilling general public health and civic responsibilities, managing pharmacy operations, and managing pharmacy personnel. Approaches to intern evaluation, preceptor and site evaluation and program evaluation are examined, and the pharmacist's participation in association activities, continuing education pursuits, and maintenance of drug information are addressed. Information concerning the development of performance objectives and a list of pharmacy library references are appended. (SW)
