Background: An estimated 40 million Americans have serum cholesterol levels that warrant medically supervised dietary intervention. Although registered dietitians are expected to play an important role in treating these patients, current treatment practices in the community are largely unknown.
Methods: A questionnaire concerning treatment practices was mailed to all 377 registered dietitians listed in the directories of the American Dietetic Association for two large California districts. Number of patients seen and length and content of dietary counseling were ascertained for three types of patients: (a) hypercholesterolemic outpatients without heart disease, (b) hypercholesterolemic outpatients who have heart disease, and (c) inpatients with myocardial infarction.
Results: A return rate of 59% (n = 252) was obtained for the questionnaire. A total of 44% of the registered dietitians counseled hypercholesterolemic patients in any of the categories surveyed. About 30% of the respondents counseled hypercholesterolemic outpatients without heart disease. They saw an average of 4.9 such patients a week, spent an average of 53 min in an initial session, and usually did not see the patient again in follow-up. Fewer than 10% of patients had as many as four sessions. About 27% of the respondents saw hypercholesterolemic outpatients with heart disease, averaging 3.5 such contacts per week. The reported practices were similar to those provided to noncardiac outpatients. About 22% of registered dietitians worked with hospitalized myocardial infarction patients. They spent an average of a total of 41 min over 2.5 visits with each patient.
Conclusion: Currently, outpatient registered dietitian counseling for hypercholesterolemia appears to be limited in both the number of patients reached and the duration of the counseling. Further research into the impact of, barriers to, and efficacy of alternative delivery methods of dietary counseling is needed.

Introduction: Individuals with esophageal and gastroesophageal junction (GEJ) cancers are at especially high risk of malnutrition. However, most patients with malnutrition do not receive adequate nutritional support. We conducted a single-arm trial to test the implementation of Support Through Remote Observation and Nutrition Guidance (STRONG), a multilevel digital intervention to improve nutritional outcomes for patients with locally advanced esophageal and gastroesophageal junction cancer.

South Africa faces both under- and over-nutrition, highlighting the need for prioritizing nutrition services. Registered dietitians are crucial for delivering appropriate and quality nutrition services. Consequently, this case study employs the World Health Organization evidence-based Workload Indicators of Staffing Need to ascertain the requisite dietetic workforce needed at central and tertiary public hospitals in South Africa.
