The University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences has been involved in the postgraduate training of pharmacy residents since 1990. Pharmacy postgraduate training is administered in conjunction with the University of Colorado Hospital (UCH) Department of Pharmacy, and UCH serves as the primary training site for all residents. Two types of residencies are offered by the School of Pharmacy, pharmacy practice residencies and specialized pharmacy practice residencies. All residencies are accredited by the American Society of Health-Systems Pharmacists (ASHP), the nation's primary accrediting body for pharmacy postgraduate training programs. The purpose of pharmacy practice residencies is to provide new pharmacy graduates with training and education in the fundamentals of exemplary contemporary pharmacy practice in organized health-care systems. This training is achieved by providing residents with opportunities to conceptualize, integrate, and transform accumulated experiences and knowledge into improved drug therapy which will lead to improved patient outcomes. The purpose of specialized residencies is to provide additional training to develop expert knowledge, skills, attitudes and abilities in a specialized area of pharmacy practice. Specialized residencies build upon the broad-based knowledge and skills, values, and clinical judgment achieved during pharmacy practice residencies, deepening the residents' ability to provide pharmaceutical care in the most complex of cases or in the support of care at the departmental level of management.
