A clinical nutrition support pharmacist training program, in collaboration with the Spanish Foundation of Hospital Pharmacy, Spanish Society of Clinical Nutrition, Abbott Nutrition International, University of Tennessee, College of Pharmacy and Regional One Health, is described. Nutrition support pharmacists from Spain were selected to participate in a one-month training program with an experienced board-certified nutrition support pharmacist faculty member within an interdisciplinary nutrition support team environment in the U.S. Participants were expected to actively engage in an advanced clinical practice role with supervision. Clinical activities included daily intensive patient monitoring, physical assessment, critical evaluation of the patient and development of an appropriate treatment plan for patients receiving either enteral or parenteral nutrition therapy. Upon successful completion of the training program, participants were anticipated to incorporate these techniques into their current practice in Spain and to train other pharmacists to function in an advanced clinical role independently or within an interdisciplinary nutrition support team environment.
