Attitudes of Healthcare Professionals toward Patient Counseling on Drug-Nutrient Interactions

OBJECTIVE: To evaluate the attitudes of healthcare providers on drug—nutrient interaction (DNI) counseling. DESIGN: A mail survey. SETTING: Random sample of healthcare providers with interest in nutrition, practicing in Iowa or Nebraska. METHODS: A 48-item questionnaire was constructed on the basis of a review of DNI literature. The survey was sent to 100 pharmacists, 50 registered dietitians, 25 registered nurses, and 25 physicians identified from culled mailing lists of the American Society of Parenteral and Enteral Nutrition and the Iowa Nebraska Society of Parenteral and Enteral Nutrition. Assessed variables included the amount of DNI counseling provided, who is in the best position to provide DNI counseling, and what information should be included in instructional materials on DNIs for patients. Data were entered into a relational database for evaluation and comparison. RESULTS: The usable response rate was 49.5 percent (n=99): 49 pharmacists, 29 dietitians, 18 nurses, and 3 physicians. Only 12 respondents provided DNI counseling in >50 percent of patient interactions. Seventy-one respondents (72 percent) felt pharmacists were in the best position to discuss DNIs with patients. More than half of the respondents felt a new DNI pamphlet should be developed to replace an existing Food and Drug Administrationsponsored pamphlet. Although 70 percent felt the new pamphlet should be organized according to specific drugs, many felt the format should also include specific populations and disease states. Eighty-six percent indicated that a chart on ONIs geared toward healthcare professionals would be useful. CONCLUSIONS: Patient-oriented resources should be developed to enhance DNI counseling. Pharmacists are in a uniquely advantageous position to provide DNI counseling.
