Medical Nutrition Therapy in Adults with Chronic Kidney Disease: Integrating Evidence and Consensus into Practice for the Generalist Registered Dietitian Nutritionist

Chronic kidney disease is classified in stages 1 to 5 by the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative depending on the level of renal function by glomerular filtration rate and, more recently, using further categorization depending on the level of glomerular filtration rate and albuminuria by the Kidney Disease Improving Global Outcomes initiative. Registered dietitian nutritionists can be reimbursed for medical nutrition therapy in chronic kidney disease stages 3 to 4 for specific clients under Center for Medicare and Medicaid Services coverage. This predialysis medical nutrition therapy counseling has been shown to both potentially delay progression to stage 5 (renal replacement therapy) and decrease first-year mortality after initiation of hemodialysis. The Joint Standards Task Force of the American Dietetic Association (now the Academy of Nutrition and Dietetics), the Renal Nutrition Dietetic Practice Group, and the National Kidney Foundation Council on Renal Nutrition collaboratively published 2009 Standards of Practice and Standards of Professional Performance for generalist, specialty, and advanced practice registered dietitian nutritionists in nephrology care. The purpose of this article is to provide an update on current recommendations for screening, diagnosis, and treatment of adults with chronic kidney disease for application in clinical practice for the generalist registered dietitian nutritionist using the evidence-based library of the Academy of Nutrition and Dietetics, published clinical practice guidelines (ie, National Kidney Foundation Council on Renal Nutrition, Renal Nutrition Dietetic Practice Group, Kidney Disease Outcomes Quality Initiative, and Kidney Disease Improving Global Outcomes), the Nutrition Care Process model, and peer-reviewed literature.     

Position of the Academy of Nutrition and Dietetics: Individualized Nutrition Approaches for Older Adults: Long-Term Care,Post-Acute Care,and Other Settings

It is the position of the Academy of Nutrition and Dietetics that the quality of life and nutritional status of older adults in long-term care, post-acute care, and other settings can be enhanced by individualized nutrition approaches. The Academy advocates that as part of the interprofessional team, registered dietitian nutritionists assess, evaluate, and recommend appropriate nutrition interventions according to each individual’s medical condition, desires, and rights to make health care choices. Nutrition and dietetic technicians, registered assist registered dietitian nutritionists in the implementation of individualized nutrition care, including the use of least restrictive diets. Health care practitioners must assess risks vs benefits of therapeutic diets, especially for frail older adults. Food is an essential component of quality of life; an unpalatable or unacceptable diet can lead to poor food and fluid intake, resulting in malnutrition and related negative health effects. Including older individuals in decisions about food can increase the desire to eat and improve quality of life.     

Research at the Academy of Nutrition and Dietetics: What,How, and Why?

Research is essential to further advance our understanding of the role of nutrition and dietetics in maintenance and improvement of health. Research is also essential for nutrition and dietetics practitioners to create and provide evidence-based interventions, including medical nutrition therapy provided by registered dietitian nutritionists. Given this critical role of research, the Academy of Nutrition and Dietetics (Academy) has a variety of resources to assist its members in accessing, understanding, participating in, conducting, and disseminating nutrition research. These resources are comprehensive and include opportunities to participate in research (eg, Nutrition Research Network and Data Science Center), tools to aggregate practice data (Nutrition Care Process and Terminology and the Academy of Nutrition and Dietetics Informatics Infrastructure), funding opportunities to support primary research (eg, Academy Foundation), resources to understand the latest research informing evidence-based practice (eg, Evidence Analysis Center), and avenues for sharing research findings (eg, Food & Nutrition Conference & Expo?). The aim of this article is to encourage Academy members to get involved in research by describing Academy-based research resources and opportunities to contribute to nutrition and dietetics research, as well as describe specific examples of research conducted at the Academy. The information presented can serve as a framework to guide members in engaging in research through the Academy.     

Academy of Nutrition and Dietetics and National Kidney Foundation: Revised 2014 Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (Competent,Proficient, and Expert) in Nephrology Nutrition

Compelling evidence indicates that the incidence of chronic kidney disease (CKD) is increasing because of an aging population and a higher prevalence of cardiovascular disease, diabetes, and hypertension. Nutrition management of patients with CKD requires early disease recognition, appropriate interpretation of the markers and stages of CKD, and collaboration with other health care practitioners. Better management of CKD can slow its progression, prevent metabolic complications, and reduce cardiovascular related outcomes. Caring for patients with CKD necessitates specialized knowledge and skills to meet the challenges associated with this growing epidemic. The Academy of Nutrition and Dietetics Renal Dietitians Practice Group and the National Kidney Foundation Council on Renal Nutrition, with guidance from the Academy of Nutrition and Dietetics Quality Management Committee, have updated the 2009 Standards of Practice in Nutrition Care and Standards of Professional Performance as a tool for registered dietitian nutritionists working in nephrology nutrition to assess their current skill levels and to identify areas for additional professional development in this practice area. The Standards of Practice apply to the care of patients/clients with kidney disease. The Standards of Professional Performance consist of six domains of professionalism, including: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements that illustrate how nephrology nutrition principles can be applied to practice. The indicators describe three skill levels (ie, competent, proficient, and expert) for registered dietitian nutritionists working in nephrology nutrition.     

Practice Paper of the Academy of Nutrition and Dietetics Abstract: Oral Health and Nutrition

This paper supports the “Position of the Academy of Nutrition and Dietetics: Oral Health and Nutrition” published in the May 2013 Journal of the Academy of Nutrition and Dietetics. It is the position of the Academy of Nutrition and Dietetics that nutrition is an integral component of oral health. The Academy supports integration of oral health with nutrition services, education, and research. Collaboration between registered dietitian nutritionists (RDNs); dietetic technicians, registered (DTRs); and oral health care professionals is recommended for oral health promotion and disease prevention and intervention. There is a synergistic multidirectional association between diet, nutrition, and oral health. Given that the mouth is the portal of entry into the body, it is essential that RDNs and DTRs include the oral cavity in their assessment for nutritional risk factors and deficiencies. Nutrition assessment is vital to identifying dietary intake and nutritional factors impacting oral health. Conversely, decreased salivary flow, compromised oral integrity, tooth decay, or poor periodontal health can impact an individual's ability to consume an adequate diet. A poor diet can result in limited intake of nutrients crucial to systemic health and well-being. The provision of medical nutrition therapy that incorporates total health, including oral health, is a component of the Standards of Practice for RDNs and DTRs. Inclusion of didactic and clinical practice concepts that illustrate the role of nutrition in oral health is essential in education programs for both professional groups. The multifaceted interactions between diet, nutrition, and oral health in practice, education, and research in both dietetics and dentistry merit the need for collaborative efforts to ensure comprehensive patient care.     

Position of the Academy of Nutrition and Dietetics and the Society for Nutrition Education and Behavior: Food and Nutrition Programs for Community-Residing Older Adults

Given the increasing number and diversity of older adults and the transformation of health care services in the United States, it is the position of the Academy of Nutrition and Dietetics and the Society for Nutrition Education and Behavior that all older adults should have access to evidence-based food and nutrition programs that ensure the availability of safe and adequate food to promote optimal nutrition, health, functionality, and quality of life. Registered dietitian nutritionists and nutrition and dietetics technicians, registered, in partnership with other practitioners and nutrition educators, should be actively involved in programs that provide coordinated services between the community and health care systems that include regular monitoring and evaluation of programming outcomes. The rapidly growing older population, increased demand for integrated continuous support systems, and rising cost of health care underscore the need for these programs. Programs must include food assistance and meal programs, nutritional screening and assessment, nutrition education, medical nutrition therapy, monitoring, evaluation, and documentation of evidence-based outcomes. Coordination with long-term care services and support systems is necessary to allow older adults to remain in their homes; improve or maintain their health and manage chronic disease; better navigate transitions of care; and reduce avoidable hospital, acute, or long-term care facility admissions. Funding of these programs requires evidence of their effectiveness, especially regarding health, functionality, and health care–related outcomes of interest to individuals, caregivers, payers, and policy makers. Targeting of food and nutrition programs involves addressing unmet needs for services, particularly among those at high risk for poor nutrition. Registered dietitian nutritionists and nutrition and dietetics technicians, registered must increase programmatic efforts to measure outcomes to evaluate community-based food and nutrition services.Position StatementIt is the position of the Academy of Nutrition and Dietetics and the Society for Nutrition Education and Behavior that older adults should have access to evidence-based food and nutrition programs that ensure the availability of safe and adequate food to promote optimal nutrition, health, functionality, and quality of life.

Academy of Nutrition and Dietetics Nutrition Research Network: Validation of a Novel Nutrition Informatics Tool to Assess Agreement Between Documented Nutrition Care and Evidence-Based Recommendations

More evidence regarding registered dietitian nutritionist implementation of evidence-based nutrition practice guidelines (EBNPGs) is needed. We assessed the utility of an automated informatics tool to evaluate congruence of documented nutrition care with 13 individual recommendations in the diabetes mellitus (DM) EBNPG and with the guideline overall. A concurrent validation study was conducted using Nutrition Care Process Terminology documentation entered in the Academy of Nutrition and Dietetics Health Informatics Infrastructure by registered dietitian nutritionists caring for patients with DM. A 15% subset (n = 115) of the 790 patient encounters recorded were selected randomly, and the documented care was evaluated using the automated DM Expected Care Plan (ECP) Analyzer and expert audit. Recommendation-level congruence, as determined by each method, was compared using Cohen’s κ analysis, and the accuracy, sensitivity, and specificity of the DM ECP Analyzer for assessing overall guideline-level congruence was calculated with expert audits as the “gold standard.” For recommendation-level congruence, the DM ECP Analyzer identified more instances of recommendation implementation in the patient encounters, and classified more encounters as including partial or full recommendation implementation for 10 of the 13 recommendations, compared with the expert audit. There was slight to fair agreement between the DM ECP and the expert audit for most individual recommendations, with a mean ± standard deviation level of agreement of κ = .17 ± .19 across all eligible recommendations. At the guideline level, the DM Analyzer had high accuracy (98.3%) and sensitivity (99.1%) and low specificity (0%; no true negatives detected). The DM ECP Analyzer is acceptable for conducting automated audits of nutrition documentation to assess congruence of documented care with recommendations for evidence-based care. Future changes to the EBNPG, Nutrition Care Process Terminology, Academy of Nutrition and Dietetics Health Informatics Infrastructure, and the DM ECP Analyzer could potentially improve recommendation-level performance. The DM ECP Analyzer can be modified for other EBNPGs to facilitate automated assessment of guideline implementation.     

Position of the Academy of Nutrition and Dietetics: Nutrition Informatics

It is the position of the Academy of Nutrition and Dietetics that nutrition informatics is a rapidly evolving area of practice for registered dietitian nutritionists and nutrition and dietetic technicians, registered; and that the knowledge and skills inherent to nutrition informatics permeate all areas of the dietetics profession. Further, nutrition and dietetics practitioners must continually learn and update their informatics knowledge and skills to remain at the forefront of nutrition practice. Nutrition informatics is the intersection of information, nutrition, and technology. However, informatics is not just using technology to do work. The essence of nutrition informatics is to manage nutrition data in combination with standards, processes, and technology to improve knowledge and practice that ultimately lead to improved quality of health care and work efficiency. Registered dietitian nutritionists and nutrition and dietetic technicians, registered, are already experts in using evidence to practice in all areas of nutrition and dietetics. To remain at the forefront of technological innovation, the profession must actively participate in the development of standards, processes, and technologies for providing nutrition care.     

Academy of Nutrition and Dietetics: Revised 2014 Standards of Professional Performance for Registered Dietitian Nutritionists in Management of Food and Nutrition Systems

Management in food and nutrition systems is presented with an ever-challenging tension between effective utilization of manpower resources, mechanical equipment, financial management, material production, and time constraints to produce optimal products. Management drives opportunities for personal development for multiple levels of its employee workforce. Given an increasing need to deliver high-quality food and services to satisfied customers, the Management in Food and Nutrition Systems Dietetic Practice Group, with guidance from the Academy of Nutrition and Dietetics Quality Management Committee, has developed the Revised 2014 Standards of Professional Performance, which replace the 2009 Standards, as a tool for registered dietitian nutritionists working in food and nutrition systems management within health care and non−health care organizations. These Standards of Professional Performance consist of six domains of professionalism: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements that illustrate how strong communication skills, attention to customer satisfaction, use of various resources, and application of personnel management principles can be applied to practice. The indicators describe three skill levels (ie, competent, proficient, and expert) for registered dietitian nutritionists managing food and nutrition systems.     

Practice Paper of the Academy of Nutrition and Dietetics: Comprehensive Nutrition Programs and Services in Schools

It is the position of the Academy of Nutrition and Dietetics, School Nutrition Association (SNA), and Society for Nutrition Education and Behavior (SNEB) that comprehensive, integrated nutrition programs in preschool through high school are essential to improve the health, nutritional status, and academic performance of our nation’s children. To maximize impact, the Academy, SNA, and SNEB recommend specific strategies in the following key areas: food and nutrition services available throughout the school campus, nutrition initiatives such as Farm to School and school gardens, wellness policies, nutrition education and promotion, and consideration of roles and responsibilities. This paper supports the joint position paper of the Academy of Nutrition and Dietetics, SNA, and SNEB published in the May 2018 Journal of Academy of Nutrition and Dietetics. In alignment with the joint position paper, this practice paper provides registered dietitian nutritionists and nutrition and dietetics technicians, registered with an overview of current school nutrition services and opportunities for professional careers in school settings. The Academy of Nutrition and Dietetics has several position papers related to youth preschool through adolescence that cover specific nutrition needs in more detail at www.eatright.org.     

Practice Paper of the Academy of Nutrition and Dietetics Abstract: Ethical and Legal Issues of Feeding and Hydration

It is the position of the Academy of Nutrition and Dietetics that individuals have the right to request or refuse nutrition and hydration as medical treatment. Registered dietitians should work collaboratively as part of an interprofessional team to make recommendations on providing, withdrawing, or withholding nutrition and hydration in individual cases and serve as active members of institutional ethics committees. This practice paper provides a proactive, integrated, systematic process to implement the Academy's position. The position and practice papers should be used together to address the history and supporting information of ethical and legal issues of feeding and hydration identified by the Academy. Elements of collaborative ethical deliberation are provided for pediatrics and adults and in different conditions. The process of ethical deliberation is presented with the roles and responsibilities of the registered dietitian and the dietetic technician, registered. Understanding the importance and applying concepts dealing with cultural values and religious diversity is necessary to integrate clinical ethics into nutrition care. Incorporating screening for quality-of-life goals is essential before implementing the Nutrition Care Process and improving health literacy with individual interactions. Developing institution-specific policies and procedures is necessary to accelerate the practice change with artificial nutrition, clinical ethics, and quality improvement projects to determine best practice. This paper supports the “Position of the Academy of Nutrition and Dietetics: Ethical and Legal Issues of Feeding and Hydration” published in the June 2013 issue of the Journal of the Academy of Nutrition and Dietetics.     

Applying Contemporary Machine Learning Approaches to Nutrition Care Real-World Evidence: Findings From the National Quality Improvement Data Set

Using real-world data from the Academy of Nutrition and Dietetics Health Informatics Infrastructure, we use state-of-the-art clustering techniques to identify 2 phenotypes characterizing the episodes of nutrition care observed in the National Quality Improvement (NQI) registry data set. The 2 phenotypes identified from recorded Nutrition Care Process data in the NQI exhibit a strong correspondence with the clinical expertise of registered dietitian nutritionists. For one of these phenotypes, it was possible to implement state-of-the-art classification techniques to predict the nutrition problem-resolution status of an episode of care. Prediction results show that the assessment of nutrition history, number of recorded visits in the episode, and use of nutrition counseling interventions were significantly and positively correlated with problem resolution. Meanwhile, evaluations of nutrition history that were not within the desired ranges were significantly and negatively correlated with problem resolution. Finally, we assess the usefulness of the current NQI data set and data model for supporting the application of contemporary machine learning methods to the data set. We also suggest ways of enhancing the NQI since registered dietitian nutritionists are encouraged to continue to contribute patient cases in this and other registry nutrition studies.     

Academy of Nutrition and Dietetics: Revised 2022 Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (Competent,Proficient, and Expert) in Adult Weight Management

A person’s weight is an anthropometric measure factored into assessing health risk, not a measure of worth, ability, or overall health. Adult weight management is a spectrum of lifelong care services available for persons whose goals can be achieved through evidence-based, weight-related interventions and intersects most practice areas of nutrition. An adult weight management registered dietitian nutritionist (RDN) is responsible for providing a psychologically safe, accessible, and respectful setting and empowering care to those seeking nutrition services. This requires the RDN to act as an advocate by proactively seeking to identify personal and external weight biases, understanding the influence of those predispositions, and acknowledging how weight-related prejudices are intricately connected with systems that influence nutrition both inside and outside of health care. Increases in average weight influence potentially counterproductive discussions about judgment, an individual’s body, and relationship with health. RDNs are equipped to provide dynamic care and be on the forefront of implementing weight-inclusive built environments, policies, and person-centered communications to minimize harm and maximize benefit for the individual and society. The authors, Weight Management Dietetic Practice Group, and the Academy of Nutrition and Dietetics Quality Management Committee revised the Standards of Practice and Standards of Professional Performance for RDNs in Adult Weight Management to update established criteria of competent practice, further define core values, and set direction for future areas of opportunity. The Adult Weight Management Standards of Practice and Standards of Professional Performance are complementary tools intended for RDNs to benchmark and identify progressive routes and goals for professional advancement.     

Position of the Academy of Nutrition and Dietetics: Benchmarks for Nutrition in Child Care

It is the position of the Academy of Nutrition and Dietetics that early care and education (ECE) programs should achieve recommended benchmarks to meet children’s nutrition needs and promote children’s optimal growth in safe and healthy environments. Children’s dietary intake is influenced by a number of factors within ECE, including the nutritional quality of the foods and beverages served, the mealtime environments, and the interactions that take place between children and their care providers. Other important and related health behaviors that may influence the development of obesity include children’s physical activity, sleep, and stress within child care. Recent efforts to promote healthy eating and improve other health behaviors in ECE include national, state, and local policy changes. In addition, a number of interventions have been developed in recent years to encourage healthy eating and help prevent obesity in young children in ECE. Members of the dietetics profession, including registered dietitian nutritionists and nutrition and dietetics technicians, registered, can work in partnership with ECE providers and parents to help promote healthy eating, increase physical activity, and address other important health behaviors of children in care. Providers and parents can serve as role models to support these healthy behaviors. This Position Paper presents current evidence and recommendations for nutrition in ECE and provides guidance for registered dietitian nutritionists; nutrition and dietetics technicians, registered; and other food and nutrition practitioners working with parents and child-care providers. This Position Paper targets children ages 2 to 5 years attending ECE programs and highlights opportunities to improve and enhance children’s healthy eating while in care.     

Prevention of Pediatric Overweight and Obesity: Position of the Academy of Nutrition and Dietetics Based on an Umbrella Review of Systematic Reviews

This Academy of Nutrition and Dietetics Position Paper reports current evidence on pediatric overweight and obesity prevention interventions and discusses implications for registered dietitian nutritionists (RDNs). An overview of current systematic reviews provided evidence-based results from a range of nutrition interventions according to developmental age group (ages 2 to 5, 6 to 12, and 13 to 17 years). Twenty-one current systematic reviews of nutrition interventions demonstrated a beneficial effect of nutrition and physical activity interventions on body mass index measures and no adverse events were identified. RDNs impart nutrition expertise in a wide range of settings to provide comprehensive care for children and adolescents as their nutrition and developmental needs change over time. This Position Paper outlines the current roles of, and proposed directions for, RDNs engaged in pediatric overweight and obesity prevention. Prevention of pediatric overweight and obesity requires comprehensive strategies ranging from policy-level to individual-level interventions in settings that will have the most beneficial impact for children according to their developmental stage. This Position Paper advocates for increased availability of nutrition and food access programs and interventions to reduce risk of pediatric obesity and associated adverse health outcomes both now and for future generations.     

Telehealth During the COVID-19 Pandemic: A Cross-Sectional Survey of Registered Dietitian Nutritionists

During the current coronavirus disease 2019 (COVID-19) pandemic, health care practices have shifted to minimize virus transmission, with unprecedented expansion of telehealth. This study describes self-reported changes in registered dietitian nutritionist (RDN) practice related to delivery of nutrition care via telehealth shortly after the onset of the COVID-19 pandemic in the United States. This cross-sectional, anonymous online survey was administered from mid-April to mid-May 2020 to RDNs in the United States providing face-to-face nutrition care prior to the COVID-19 pandemic. This survey included 54 questions about practitioner demographics and experience and current practices providing nutrition care via telehealth, including billing procedures, and was completed by 2016 RDNs with a median (interquartile range) of 15 (6-27) years of experience in dietetics practice. Although 37% of respondents reported that they provided nutrition care via telehealth prior to the COVID-19 pandemic, this proportion was 78% at the time of the survey. Respondents reported spending a median (interquartile range) of 30 (20-45) minutes in direct contact with the individual/group per telehealth session. The most frequently reported barriers to delivering nutrition care via telehealth were lack of client interest (29%) and Internet access (26%) and inability to conduct or evaluate typical nutrition assessment or monitoring/evaluation activities (28%). Frequently reported benefits included promoting compliance with social distancing (66%) and scheduling flexibility (50%). About half of RDNs or their employers sometimes or always bill for telehealth services, and of those, 61% are sometimes or always reimbursed. Based on RDN needs, the Academy of Nutrition and Dietetics continues to advocate and provide resources for providing effective telehealth and receiving reimbursement via appropriate coding and billing. Moving forward, it will be important for RDNs to participate fully in health care delivered by telehealth and telehealth research both during and after the COVID-19 public health emergency.     

Academy of Nutrition and Dietetics: Revised 2017 Standards of Practice and Standards of Professional Performance for Registered Dietitian Nutritionists (Competent,Proficient, and Expert) in Oncology Nutrition

Oncology nutrition encompasses nutrition care for individuals along the cancer care continuum. Nutrition is a vital component of prevention, treatment, and healthy survivorship. The practice of an oncology registered dietitian nutritionist (RDN) reflects the setting and population served with diverse cancer diagnoses, including expanded roles and responsibilities reflecting the RDN’s interests and organization’s activities. Provision of nutrition services in oncology requires that RDNs have advanced knowledge in the focus area of oncology nutrition. Thus, the Oncology Nutrition Dietetic Practice Group, with guidance from the Academy of Nutrition and Dietetics Quality Management Committee, has developed Standards of Practice and Standards of Professional Performance as tools for RDNs currently in practice or interested in working in oncology nutrition, to address their current skill level and to identify areas for additional professional development in this practice area. The Standards of Practice address and apply the Nutrition Care Process and workflow elements, which are screening, assessment, diagnosis, intervention, evaluation/monitoring, and discharge planning and transitions of care. The Standards of Professional Performance consist of the following six domains of professionalism including: Quality in Practice, Competence and Accountability, Provision of Services, Application of Research, Communication and Application of Knowledge, and Utilization and Management of Resources. Within each standard, specific indicators provide measurable action statements and describe three skill levels (competent, proficient, and expert) for RDNs working in oncology nutrition.     

Position of the Academy of Nutrition and Dietetics: Food and Water Safety

It is the position of the Academy of Nutrition and Dietetics that all people should have access to a safe food and water supply. The Academy of Nutrition and Dietetics supports science-based food and water regulations and recommendations that are applied consistently across all foods and water regulated by all agencies and incorporate traceability and recall to limit food- and waterborne outbreaks. Registered dietitian nutritionists and dietetic technicians, registered, are encouraged to participate in policy decisions, program development, and implementation of a food safety culture. Food safety affects all segments of the population in a global society, and, although the United States food and water system has many protections in place, food safety continues to be a public health concern. The Centers for Disease Control and Prevention estimates that one in six Americans are sickened, 128,000 are hospitalized, and 3,000 die annually from foodborne disease. Using the Centers for Disease Control and Prevention estimates for foodborne illness, it is estimated that the basic cost-of-illness averages $1,068/episode with a total annual cost of $51 billion. The food safety system is challenged by changing demographics, consumer preferences for convenience and variety, and issues of concern in the commercial food chain and in regulatory systems. The 2011-enacted Food Safety Modernization Act is an extensive expansion of federal food regulatory authority that mandates a risk-based food safety system approach and focuses on comprehensive science-based preventive measures across the total food safety system. Registered dietitian nutritionists and dietetic technicians, registered, have unique roles in promoting and establishing food safety cultures in foodservice settings, clinical practices, community settings, and in public venues because their training integrates food; science; and health, both preventive and therapeutic.     

Trends in Registered Dietitian Nutritionists’ Knowledge and Patterns of Coding,Billing, and Payment

The US health care system has been undergoing substantial changes in reimbursement for medical and nutrition services. These changes have offered opportunities and challenges for registered dietitian nutritionists (RDNs) to bill for medical nutrition therapy and other nutrition-related services. During the past 10 years, the Academy of Nutrition and Dietetics has periodically surveyed RDNs providing medical nutrition therapy in ambulatory care settings to learn about their knowledge and patterns of coding, billing, and payment for their services. In 2018, the Academy of Nutrition and Dietetics conducted the latest iteration of this survey. This article compares the results of the 2008, 2013, and 2018 surveys to examine changes in RDNs’ knowledge of billing code use and reimbursement patterns over time; understand the potential influences on coding and billing practices in a changing health care environment; and understand the effects of newer practice settings and care delivery models on billing and reimbursement for medical nutrition therapy services. Results from these surveys demonstrate that during the past 10 years RDNs’ knowledge of billing and coding has been stable and very low for RDNs not in supervisory roles or private practice. RDNs reported an increase in providing medical nutrition therapy services to patients with multiple conditions. Since 2013, a dramatic increase was noted in the reported proportion of reimbursement from private/commercial health insurance plans. Results also indicate that most RDNs are not aware of changes in health care payment. Individual RDNs need to understand and be held accountable for the business side of practice and their value proposition in today’s health care environment.
