Reprint of: Position of the Academy of Nutrition and Dietetics: Malnutrition (Undernutrition) Screening Tools for All Adults.

It is the position of the Academy of Nutrition and Dietetics that, based upon current evidence, the Malnutrition Screening Tool should be used to screen adults for malnutrition (undernutrition) regardless of their age, medical history, or setting. Malnutrition (undernutrition) screening is a simple process intended to quickly recognize individuals who may have a malnutrition diagnosis. While numerous malnutrition screening tools are in use, their levels of validity, agreement, reliability, and generalizability vary. The Academy of Nutrition and Dietetics reviewed the body of evidence supporting malnutrition screening tools and determined a single tool for identifying adults in all settings who may have malnutrition, regardless of their age or medical history. The Nutrition Screening for Adults Workgroup conducted a systematic review of the most robust evidence to promote using the highest-quality malnutrition screening tool available.

Commentary on "Prevalence of Malnutrition and 1-Year All-Cause Mortality in Institutionalized Elderly Comparing Different Combinations of the GLIM Criteria".

The nutrition community has worked to develop an international understanding of diagnostic criteria for malnutrition. In this Commentary are thoughts on a clinical utility study of the latest standard malnutrition definition, the Global Leadership in Malnutrition (GLIM) criteria. In "Prevalence of malnutrition and 1-year all-cause mortality in institutionalized elderly comparing different combinations of the GLIM criteria," the authors created and then compare each of 12 different combinations of the GLIM components in a Spanish nursing home sample and find a higher mortality rate among participants with malnutrition and inflammation than participants with malnutrition alone. In working toward the advantages offered by a rigorously validated and internationally accepted malnutrition definition that is age, sex, location, race, and ethnicity neutral, there are several points to consider. There is a strong need to eliminate clinician-, disease-, or location-specific malnutrition criteria in favor of definitions that apply broadly, are specific to malnutrition rather than disease or location, and are validated against a malnutrition standard. With the GLIM criteria, it is likely that some existing malnutrition screening tools will overestimate malnutrition risk because they contain common criteria that do not change in response to malnutrition intervention. With consistent criteria, consistently applied, it is likely that the overall prevalence of malnutrition will change in some groups. malnutrition; nutrition assessment; adult malnutrition; geriatric malnutrition.

Adult Malnutrition (Undernutrition) Screening: An Evidence Analysis Center Systematic Review.

BACKGROUND: Malnutrition screening relies on quick and easy-to-use tools that require minimal training of users. Valid and reliable tools should avoid under-referral of adults with a malnutrition diagnosis or over-referral of those without a malnutrition diagnosis to dietitians. OBJECTIVE: Our aim was to conduct a systematic review of adult malnutrition screening tools for validity, agreement, and reliability, and to determine the costs of the malnutrition screening procedure. METHODS: Following a structured process, a comprehensive search using PubMed, MEDLINE, EMBASE, and CINAHL was conducted for relevant research published between 1997 and 2017 that examined the validity, agreement, reliability, and costs of nutrition screening tools. RESULTS: Sixty-nine studies met the inclusion criteria. The Malnutrition Screening Tool exhibited moderate validity, agreement, and reliability based on Grade I (Good/Strong) evidence. The evidence supporting the conclusions for the remaining tools was Fair (Grade II). The Malnutrition Universal Screening Tool exhibited high validity and moderate agreement and reliability. The Mini Nutritional Assessment-Short Form exhibited moderate validity and reliability and low agreement. The Short Nutritional Assessment Questionnaire and the Nutrition Risk Screening 2002 exhibited moderate validity and reliability and the Mini Nutritional Assessment-Short Form Body Mass Index exhibited high validity and moderate agreement. However, these last three tools were missing reliability or agreement data. Limited data were available to evaluate malnutrition screening costs. CONCLUSIONS: This review provides an analysis of validity, agreement, and reliability of tools to screen adults for malnutrition, regardless of their age, medical history, or location. No tools were found with high validity, reliability, and strong supportive evidence. Tools most often achieved moderate validity, agreement, and reliability, and had large variations in individual results. The minimum validity and reliability of tools to screen adults for malnutrition should be established to shape future research. Cost data for the screening process should be obtained and examined.

How Should Physicians Counsel Patients Who Live in Food Deserts?

In this case, a physician wonders what he should do to help make nutrient-dense foods available in underserved neighborhoods. I argue that improving diets of people who live in food deserts is a complex problem at the intersection of culture, education, and economics that will require community partnerships and clinician self-education to solve.

Framework for analyzing supply and demand for specialist and advanced practice registered dietitians.

The number of credentialed dietetics specialists--approximately 15% of the profession--is proportionately higher than those in other allied health and nursing professions. Credentialed specialists seem to receive greater compensation earlier in their career, but this advantage neutralizes as length of time in the profession increases. A larger proportion of younger registered dietitians (RDs) are specialists, which may mean an increase in supply of specialists in the future. There is considerable interest in creation of health promotion and foodservice management credentials. Consideration should be given to collaborating with other organizations to explore new models of recognition or credentialing for narrow areas of focus. Creating a methodology that can differentiate the tasks and approaches to practice that are unique to advanced practitioners compared with specialists has been a challenge. Prior research has not succeeded in identifying the differences in what advanced practitioners do. Future research to isolate advanced practice must take practice approach into account. A new, research-based, credential for advanced practitioners is possible, or a recognition program for advanced practice RDs could be considered. Precise supply and demand for specialty and advanced practice RDs cannot be measured. Thus, in this technical article, the authors share the available information regarding supply and demand with regard to dietetics specialists and advanced practitioners. It seems there are distinctions among the various levels of practice and recognition of their value to the profession and to the health of the public.

Refeeding syndrome or refeeding hypophosphatemia: a systematic review of cases.

Nutrition support clinicians refer to the abnormalities in laboratory data and changes in clinical signs and symptoms that follow refeeding of starved or malnourished patients as refeeding syndrome. Theoretical descriptions of refeeding syndrome include a complex and extensive list of changes, such as hypophosphatemia, hypomagnesemia, hypokalemia, hyponatremia, hypocalcemia, hyperglycemia, and vitamin deficiency--all of which are accompanied by clinical signs and symptoms. In practice, clinicians see asymptomatic refeeding hypophosphatemia more often than a full-blown syndrome with multiple laboratory and clinical abnormalities. Confusion results because there is no widely accepted or uniformly applied set of defining characteristics for diagnosing refeeding syndrome. To gain insight into the clinical characteristics of refeeding syndrome described in the literature, a systematic review of reported cases and case series was conducted. Since 2000, 20 authors described 27 cases that contained sufficient data for review. Hypophosphatemia occurred in 26 patients (96%). While 19 patients (71%) experienced at least 1 other laboratory abnormality, only 14 (51%) exhibited a consistent pattern of abnormally low phosphorus and magnesium levels. Seven patients had hypocalcemia (26%), and hyponatremia was reported in 3 patients (11%). There were no reports of hyperglycemia. Mean data reported in case series containing data from 63 patients showed that hypophosphatemia was a consistent finding but that other abnormalities were not consistently identified. Findings suggest that refeeding hypophosphatemia is not accompanied by a consistent pattern of biochemical or clinical abnormalities among case reports or case series of patients reported to have refeeding syndrome.

Nutrition screening tools: an analysis of the evidence.

In response to questions about tools for nutrition screening, an evidence analysis project was developed to identify the most valid and reliable nutrition screening tools for use in acute care and hospital-based ambulatory care settings. An oversight group defined nutrition screening and literature search criteria. A trained analyst conducted structured searches of the literature for studies of nutrition screening tools according to predetermined criteria. Eleven nutrition screening tools designed to detect undernutrition in patients in acute care and hospital-based ambulatory care were identified. Trained analysts evaluated articles for quality using criteria specified by the American Dietetic Association's Evidence Analysis Library. Members of the oversight group assigned quality grades to the tools based on the quality of the supporting evidence, including reliability and validity data. One tool, the NRS-2002, received a grade I, and 4 tools-the Simple Two-Part Tool, the Mini-Nutritional Assessment-Short Form (MNA-SF), the Malnutrition Screening Tool (MST), and Malnutrition Universal Screening Tool (MUST)-received a grade II. The MST was the only tool shown to be both valid and reliable for identifying undernutrition in the settings studied. Thus, validated nutrition screening tools that are simple and easy to use are available for application in acute care and hospital-based ambulatory care settings.

Clinical registered dietitians, employers, and educators are interested in advanced practice education and professional doctorate degrees in clinical nutrition.

A subset of registered dietitians (RDs) is known to practice at an advanced level, but a clear educational pathway supporting advanced medical nutrition therapy practice has not been identified. Thus, an electronic survey was designed to investigate interest of clinical RDs, employers, and educators in advanced practice competencies and professional doctorate degree programs in clinical nutrition. Usable responses were obtained from 440 of 978 (45%) RDs, 61 of 107 (57%) employers, and 76 of 114 (67%) educators. Mean interest (5 = very interested, 1 = very uninterested) in obtaining advanced practice education was highest among RDs (3.93+/-1.01) and was significantly different (P < 0.01) from employers (3.74 +/-1.28) and educators (2.76+/-1.33). Interest in completing a professional doctorate in clinical nutrition was significantly (P < 0.01) different among RDs (3.05+/-1.28), employers (3.18+/-1.30), and educators (2.3+/-1.34). Employers' mean interest score for hiring RDs with a professional doctorate in clinical nutrition was 4.02+/-0.93. A subset of clinical RDs appears to be interested in obtaining advanced practice competency and enrolling in professional doctorate degrees in clinical nutrition. Clinical nutrition managers in academic medical centers may be interested in hiring advanced practice clinical RDs with professional doctorate degrees. Opportunities exist for educators to develop advanced practice educational experiences and professional doctorate degree programs.

Using initiative to achieve autonomy: a model for advanced practice in medical nutrition therapy.

The purpose of this research was to generate a model of advanced medical nutrition therapy (MNT) practice based on descriptions of their clinical activities provided by advanced-level MNT practitioners. A qualitative approach using grounded theory methodology was employed. The model of advanced MNT practice was based on interviews with 21 credentialed advanced practice registered dietitians from across the United States and Canada. Verbatim transcripts of the interviews were coded for aggregation into themes and subthemes. The resulting model included a single overarching theme: using initiative to achieve autonomy. The five subthemes are aptitude, attitude, expertise, context, and approach. The model provides a richer picture of advanced MNT practice than was previously available and is presented for discussion and debate. Validation of the model is required before incorporation into education or practice.

Is there a role for nonprotein calories in developing and evaluating the nutrient prescription?

The concept of nonprotein calories has been used in a variety of ways by nutrition support clinicians. Nonprotein calories may refer to the combined energy from lipid and carbohydrate but are also used to describe the balance between energy and protein in the form of the nonprotein calorie-to-nitrogen ratio. Nonprotein calories have been used as the basis for calculating nutrient needs, but this practice is no longer recommended as it may result in overfeeding. The purpose of this paper is to examine the nonprotein calorie concept using a clinical scenario and review of the literature.

A look at the educational preparation of the health-diagnosing and treating professions: do dietitians measure up?

Basic educational requirements for dietitians were developed almost 80 years ago and remain largely unchanged. In the interim, other health professions have increased their academic standards. A review of the educational preparation of 16 health-diagnosing and treating professions was undertaken to better understand the standards for dietetics education within a larger context. Educational standards for each profession were obtained and reviewed for types of degrees; duration of post-secondary, college-level education; division of didactic and clinical education; and presence of accredited post-professional education. Findings reveal that at least 11 of the professions studied offer first professional degrees. Differences were noted in duration and sequencing of undergraduate education, didactic or classroom education, and especially supervised practice. Models to facilitate comparison between educational standards were developed. The current educational model in dietetics is designed to prepare entry-level practitioners and academics who comprise less than 20% of the profession. This review supports the need to investigate educational opportunities for beyond-entry-level dietitians, and to develop educational programs that amplify the existing models for educating dietitians.
