Nephrologists' and internal medicine physicians' expectations of renal dietitians and general clinical dietitians.

OBJECTIVE

To document and compare nephrologists' and internal medicine physicians' expectations of renal dietitians and general clinical dietitians.

DESIGN

Subjects completed a mailed survey. Respondents provided demographic information and used a 5-point Likert scale to note whether each of 14 job functions was appropriate for general clinical dietitians, renal dietitians, or both.

SUBJECTS

Five hundred forty-one physicians registered with the Ohio State Medical Board (OSMB) were surveyed. Within this group were 283 nephrologists (the population of nephrologists registered with the OSMB) and 258 internal medicine physicians (selected randomly by the OSMB). A total of 133 physicians (25%) returned the survey; 119 surveys were usable: 70 from nephrologists and 49 from internists.

STATISTICAL ANALYSES PERFORMED

A composite variable was created by coding and summing physicians' responses regarding dietitian job functions. This variable was averaged for both physician categories. A t test was conducted to compare composite variable results between the two physician groups.

RESULTS

At least 50% of nephrologists and internists agreed that both types of dietitians should conduct nutrition assessments, determine patients' energy needs, evaluate medication-nutrient interactions, recommend diet and tube-feeding orders, instruct patients about physician-ordered diets, and teach nutrition concepts to hospital interns. Few physicians agreed that either type of dietitian should order diets, tube feedings, or diet instructions.

APPLICATIONS/CONCLUSIONS: Clinical dietitians can educate physicians about dietitians roles informally in their institutions and formally by supporting programs like The American Dietetic Association Physician Nutrition Education Program. In addition, dietetics educators can hone their students' communication and problem-solving skills to promote positive physician-dietitian interaction.
