    Author: Olree K, Skipper A.
    Journal: J Am Diet Assoc; 1997 Nov; 97(11):1255-60, 1263; quiz 1261-2. PubMed ID: 9366863.
    Abstract:
    OBJECTIVES: To determine current and ideal frequencies with which nutrition support dietitians perform each item on a list of 15 tasks and evaluate dietitian preparation for the practice of nutrition support. DESIGN: Data were collected using two questionnaires, one completed by the chief clinical dietitian and the other completed by the nutrition support dietitian at each hospital surveyed. Both versions of the questionnaires contained a list of 15 tasks that had been validated as being related to advanced nutrition support by a panel of 20 nutrition support experts using a modified Delphi method. Follow-up telephone calls were made to increase the number of responses. SAMPLE: Questionnaires were mailed to the chief clinical dietitian at 300 randomly selected, general medical/surgical hospitals with 300 or more beds in the United States and Puerto Rico. A total of 134 chief clinical dietitians (45%) and 129 nutrition support dietitians (43%) responded to the surveys; 124 (41%) and 120 (40%) questionnaires, respectively, were usable for statistical analyses. STATISTICAL ANALYSES: The Wilcoxon matched-pairs signed-ranks test was used to determine differences between nutrition support dietitian actual and ideal frequencies and between chief clinical dietitian actual and ideal frequencies for each of the 15 tasks. The Mann-Whitney U-Wilcoxon rank sum W test was used to determine differences between nutrition support dietitian and chief clinical dietitian actual frequencies and between nutrition support dietitian and chief clinical dietitian ideal frequencies for each of the 15 tasks. Descriptive statistics were used to analyze the questions regarding educational preparation for nutrition support practice and demographic data. RESULTS: The ideal frequency for each of the 15 tasks was significantly greater (P < .0001) than the actual frequency reported by nutrition support dietitians and chief clinical dietitians. Whereas chief clinical dietitians and nutrition support dietitians agreed on the ideal frequency for most tasks, the nutrition support dietitian ideal frequency indicated for the tasks "determines macronutrient composition of parenteral nutrition" and "performs physical examinations related to nutritional status, fluid status, and gastrointestinal function" was significantly greater (P < .001, P < .05), respectively) than the ideal frequency indicated by chief clinical dietitians. Of the nutrition support dietitians, 79% agreed and 16% somewhat agreed that experiences beyond those required for becoming a registered dietitian are needed to provide nutrition support dietitians with specialized clinical skills. APPLICATIONS/CONCLUSIONS: Nutrition support dietitians desire increased responsibility for delivering nutrition support to their patients and this desire is largely supported by chief clinical dietitians. Nutrition support dietitians appear to have a strong interest in postregistration qualifying experiences that would provide a foundation for expanding their roles. According to the results of this study, programs designed to provide practical, clinical experience in nutrition support are needed.
