Protein and older adults

Body composition changes as people get older. One of the noteworthy alterations is the reduction in total body protein. A decrease in skeletal muscle is the most noticeable manifestation of this change but there is also a reduction in other physiologic proteins such as organ tissue, blood components, and immune bodies as well as declines in total body potassium and water. This contributes to impaired wound healing, loss of skin elasticity, and an inability to fight infection. The recommended dietary allowance (RDA) for adults for protein is 0.8 grams of protein per kilogram of body weight. Protein tissue accounts for 30% of whole-body protein turnover but that rate declines to 20% or less by age 70. The result of this phenomenon is that older adults require more protein/kilogram body weight than do younger adults. Recently, it has become clear that the requirement for exogenous protein is at least 1.0 gram/kilogram body weight. Adequate dietary intake of protein may be more difficult for older adults to obtain. Dietary animal protein is the primary source of high biological value protein, iron, vitamin B12, folic acid, biotin and other essential nutrients. In fact, egg protein is the standard against which all other proteins are compared. Compared to other high-quality protein sources like meat, poultry and seafood, eggs are the least expensive. The importance of dietary protein cannot be underestimated in the diets of older adults; inadequate protein intake contributes to a decrease in reserve capacity, increased skin fragility, decreased immune function, poorer healing, and longer recuperation from illness.

Patterns of care: an analysis of the quality of nutritional care routinely provided to elderly hospitalized veterans.

To assess the adequacy of the nutritional care provided, a prospective noninterventional study was carried out on 250 randomly selected patients aged 65 and over who were admitted to a Veterans Administration Hospital. Of this group, 97 patients (39%) were found to be at high risk of having clinically significant protein-energy malnutrition. In 43 cases (17%), an assessment of the patients nutritional status was not possible because the available data were inadequate. No patient had a diagnosis of malnutrition recorded on the problem list. Only 13 percent of the high-risk patients received some form of nutrition support therapy; 10 (10%) received oral supplements, and four (4%) were started on enteral feedings. Patients who received enteral feedings experienced a high rate of complications resulting from use of the feeding tubes. Over all, none of the high risk study patients received optimal nutrition support therapy. These findings indicate that elderly patients hospitalized in the Veterans Administration hospital in this study are usually not screened appropriately for protein-energy malnutrition, the diagnosis is frequently missed or ignored, and nutrition support therapy is underutilized and often ineffectually managed.

Tube Feeding Patients With Dementia

As the population ages, the incidence of dementia increases. All types of dementia, whether they are reversible or irreversible, lead to loss of intellectual function and judgment, memory impairment, and personality changes. The skills to feed oneself, use eating utensils, and consume items recognized as food, thereby maintaining nutrition status, may be lost as dementia progresses. Reports indicate that nutrition status may be maintained when patients are hand fed, but this is labor intensive and therefore expensive. Feeding via a percutaneous endoscopic gastrostomy tube is often chosen as an acceptable alternative. Research indicates that there is little benefit in this population when aggressive nutrition support is instituted. Providing tube feeding to patients with dementia does not necessarily extend life, increase weight, or reduce the incidence of pressure ulcers or aspiration. There are many legal and ethical issues involved in the decision to place a feeding tube in demented patients. The primary issue in patients with dementia may be autonomy and the right of an individual to decide whether or not a tube should be placed at all. Legally, there is clear precedent that the courts see the insertion of a feeding tube as extraordinary care that the patient has the right to refuse. However, much of case law is derived from cases of patients who were in a persistent vegetative state. Advance directives help to determine what the patient would want for himself. Considering all the options before the patient can no longer make decisions is the most desirable course.

An Overview of Tube Feeding: From Ancient Times to the Future

The history of enteral feeding goes back about 3,500 years to the ancient Greeks and Egyptians, who infused nutrient solutions into the rectum to treat various bowel disorders. Over the centuries, experimentation and research have contributed to a greater understanding of nutrient requirements; methods to more accurately access the gastrointestinal tract; development of new materials to use in equipment, tubes, and containers; and the digestion, absorption, and use of macro- and micronutrients. It is notable that while advances were made in one area, progress was being made in another. For example, while enteral access and feeding techniques were being developed, essential amino acids were identified. When new information came together, rapid changes opened up the applications for enteral feeding in new directions, sometimes in unexpected ways such as diets designed for the space program, leading to the use of elemental diets as a therapeutic modality.

NEEDS ASSESSMENT OF RURAL COMMUNITIES: A FOCUS ON OLDER ADULTS

High-quality community needs assessments can help focus limited resources on the needs of a rapidly expanding population—older Americans. Based on such assessments, organizations and communities can effectively plan and deliver cost-effective, appropriate health promotion/wellness programs and health/social services to targeted populations. This article, which describes the Arkansas Aging Initiative’s (AAI) use of a community needs assessment to identify its constituents’ top health needs, provides specific background information for communities with demographics similar to those in Arkansas and offers assessment strategies for communities throughout the US. The AAI used two complementary methodologies to obtain critical input from Arkansas providers and their communities: focus groups of healthcare providers and community members and surveys administered to older adults. The assessment confirmed that health problems in the communities were consistent with leading causes of morbidity and mortality at state and national levels. It indicated that respondents’ top three health needs related to affordability, including affordability of prescription medications, medical care, and health insurance, and that needs varied inversely with age. In other findings, married individuals rated their own health as better than their single counterparts; whites rated their health better than non-whites; and more than half of respondents reported leaving their counties to receive healthcare. This community needs assessment has enabled the AAI to address respondents’ needs by developing specific educational and interdisciplinary healthcare initiatives, such as increasing access to a prescription drug assistance program.

An evaluation of provider educational needs in geriatric care.

Providers of geriatric care in Arkansas were surveyed to determine the desire for more information on their specialty as well as opportunities for further training. Those in the nursing profession were most interested in further training, and the major area of interest for all providers was in cognitive decline and mental health information. Specifically, information was sought in the areas of dementia, depression, and memory loss. It is recommended that improvement in geriatric care in the future should focus on nursing education and on raising the level of knowledge and academic prestige in the treatment of elderly patients, especially in the mental health areas.

Department of Veterans Affairs Geriatric Research, Education and Clinical Centers: Translating Aging Research into Clinical Geriatrics

Department of Veterans Affairs (VA) Geriatric Research, Education and Clinical Centers (GRECCs) originated in 1975 in response to the rapidly aging veteran population. Since its inception, the GRECC program has made major contributions to the advancement of aging research, geriatric training, and clinical care within and outside the VA. GRECCs were created to conduct translational research to enhance the clinical care of future aging generations. GRECC training programs also provide leadership in educating healthcare providers about the special needs of older persons. GRECC programs are also instrumental in establishing robust clinical geriatric and aging research programs at their affiliated university schools of medicine. This report identifies how the GRECC program has successfully adapted to changes that have occurred in VA since 1994, when the programs influence on U.S. geriatrics was last reported, focusing on its effect on advancing clinical geriatrics in the last 10 years. This evidence supports the conclusion that, after more than 30 years, the GRECC program remains a vibrant “jewel in the crown of the VA” and is poised to make contributions to aging research and clinical geriatrics well into the future.

Beyond nutrition screening: A systems approach to nutrition intervention ☆: Challenges and opportunities for dietetics professionals

Abstract Malnutrition in older Americans involves many disparate and complex causes. Dietetics professionals need to broaden their scope of practice in dealing with nutrition screening and intervention themselves and in providing expert consultation to others. Health and social services generalists such as physicians, nurses, and social workers must become more aware of the presence and risk of nutrition-related problems in the elderly and must adopt a systematic, collaborative approach to their solution. Nutrition screening, intervention, appropriate referral, and consultation must be built into daily practice. The NSI is a challenge and a call to action for all dietetics professionals. Registered dietitians must become active participants on interdisciplinary teams. They must assume a leadership role in areas of nutrition screening, assessment, and intervention. Their knowledge, skills, and expertise must continue to keep pace not only with advances in the science and technology of nutrition but also with relevant areas of related fields. The tools provided by the NSI and partnerships between nutrition and other health and social services professionals provide opportunity for the widespread incorporation of a systematic approach to delivery of nutrition services. Attention to nutritional health is too important to be left solely to health specialists or to generalists; all must become active participants in maximizing the nutritional health of older Americans.

Education partnerships between GRECCs and other VA organizations, Non-VA governmental agencies, academic medical centers, and centers of excellence

Gerontology and geriatrics are interdisciplinary professions. The quality of the care and services provided by the members of these professions depends upon the strength and integrity of the partnerships between the professionals working together. This article summarizes the partnerships created by the Department of Veterans Affairs Geriatric Research, Education, and Clinical Centers. This myriad of partners has formed the basis of successful programming to improve clinical care, to expand research projects, and most specifically, to produce educational opportunities in geriatrics and gerontology that have the potential to improve the quality of life for older Veterans.

Issues in Geriatric Nutrition

Another nutritionally vulnerable group is the institutionalized elderly, who often have multiple medical problems, need assistance with feeding, have dementia, and need total care. It is not uncommon for these individuals to have inadequate dietary intakes and to experience weight loss and decreases in lean body mass. For those who are bedor chair-bound, loss of lean body mass may be a significant consequence.
