Malnutrition in the Elderly with Dementia Essay

What is Malnutrition?Malnutrition is a state of nutrition (under or over nutrition) in which a lack of protein, energy and other nutrients causes measurable adverse effects on tissue and/or body form, composition, function or clinical outcome. We will focus on under nutrition as a nutritional concern. The main cause for concern among older mass in the UK is that they are not eating enough to maintain good nutrition. Among the existence of older pot in residential kick there are many more underweight people than there are overweight or obese people, and in old age being underweight poses a far greater run a risk to health than being overweight. The most recent study on the nutritional status of older people in Britain was reported in the National Diet and Nutrition Survey (NDNS) of people aged 65 years and over in 1998. In this survey, 3% of men and 6% of women living at home were underweight, while comparable figures for those in residential care were 16% and 15% respectively. It is suggested, however, that risk of undernutrition is still not adequately identified in older people and that undernutrition is practically associated with hospitalisation and poor health status.1 The level of undernutrition among older people with dementia in residential care is likely to be even broad(prenominal)er, with estimates that as many as 50% of older people with dementia work inadequate energy intakes. Undernutrition is related to increased mortality, increased risk of fracture, increased risk of infections and increased risk of specialized nutrient deficiencies guide to a variety of health-related conditions that can greatly affect the quality of life. Disease can also exert a potent influence on malnutrition as medical conditions can reduce food intake and impair endureion and absorption of nutrients as well as affect how the body metabolises and utilises them.The causes of undernutrition in older people in residential care are often multi-factorial low income , living alone, limited mobility, and lack of facilities and social network can lead to undernutrition before admission, and this is often exacerbated by depression, bereavement and confusion. Factors that have been associated with undernutrition in care situations include lack of palatability of food and inflexible timing of meals, lack of assistance with eating or loss of independence in eating, lack of acceptability of food provided to ethnic minorities and lack of awareness of the need for assessment and documentation of older people at risk of undernutrition.Malnutrition can be significant if a person has a BMI of less than 18.5 kg/m2 had ignorant weight loss greater than 10% indoors the last 3-6 months a BMI less than 20kg/m2 and has had unintentional weight loss greater than 5% within the last 3-6 months People are also at risk of becoming malnourished if they have eaten very little or nothing for more than 5 days and/or this pattern is likely to continue. Worryingly, mor e than 1 in 4 of all adults admitted for a hospital stay, to a mental unit or a care home is at risk of malnutrition. It is a well-documented fact that worldwide, the elderly population is increasing, and with it, the incidence of malnutrition. Malnutrition is associated with significantly increased morbidity and mortality in independently living older people, as well as in nursing home residents and hospitalised patients. Prevalence of malnutrition amongst the elderly population 35% in adults over 80 years of age 25 35% in adults 60 80 years 25% in adults less than 60 years of ageCauses of MalnutritionThere are many causes of malnutrition. These can include decrease intake Poor appetite receivable to illness, food aversion, nausea or pain when eating, depression, anxiety, side effects of medication or drug addiction inability to eat This can be due to investigations or being held nil by mouth, reduced levels of consciousness confusion difficulty in feeding oneself due to fa iling, arthritis or other conditions such as Parkinsons Disease, dysphasia, vomiting, painful mouth conditions, poor oral hygiene or dentition restrictions imposed by performance or investigations Lack of food availability poverty poor quality diet at home, in hospital or in care homes problems with obtain and cooking Impaired absorption This can be due to medical and surgical problems effecting digestion & stomach, intestine, pancreas and liver /or absorption Altered metabolism Increased or changed metabolic demands requirements related to illness e.g. cancer surgery, organ dysfunction, or treatment Excess losses Vomiting diarrhoea nutrient fistulae stomas losses from nasogastric losses furnish and other drains or skin exudates from burns People at risk of MalnutritionAs we have seen, the groups most vulnerable to malnutrition include People just fulfil from hospital Elderly people (16% in residential care) People with cancer and other long-term conditions People recovering from surgeryRisk factors more specific to the elderlyDementia and other neurological disorders Alzheimers disease Other forms of dementia Confusional syndrome Consciousness disorders ParkinsonismConsequences of MalnutritionMalnutrition can often go undetected and when left field untreated, it can have serious consequences on health, which include Increased risk to infections Delayed wound healing Impaired respiratory function Muscle weakness and depressionDetection of MalnutritionThere is no alternative to measurements of weight and height, along with other anthropometric measures in specialist circumstances. These measurements can then be utilize with the following questions Has our resident been eating a normal and varied diet in the last few weeks? Has our resident experienced intentional or unintentional weight loss recently? Rapid weight loss is a concern in all patients/residents whether obese or not Can our residents eat, swallow, digest and absorb enough food safely to m eet their likely needs? Does our resident have an unusually high need for all or virtually nutrients? Surgical stress, trauma, infection, metabolic disease, wounds, bedsores or history of poor intake may all contribute to such a need Does any treatment, disease, physical limitation or organ dysfunction limit out residents ability to handle the nutrients for current or future needs? Does our resident have excessive nutrient losses through vomiting, diarrhoea, surgical drains etc? Does a global assessment of our resident suggest under nourishment? Low body weight, slack fitting clothes, fragile skin, poor wound healing, apathy, wasted muscles, poor appetite, altered taste sensation, altered bowel habit. Discussion with relatives may be important In the light of all of the above, can our resident meet all of their requirements by voluntary choice from the food available? Understanding that asking these questions take a significant amount of time and expertise, a number of screen ing tools have been developed to help you identify whether our residents are at risk of malnutrition.Given the high prevalence of malnutrition and lack of proper management of patients/residents in various settings, performing a routine nutritional screening should result in early acknowledgment of patients/residents who might have otherwise been missed. A screening tool should help establish reliable pathways of care for patients with malnutrition. Screening for malnutrition (and the risk of malnutrition) should be carried out by healthcare professionals with appropriate skills and training.
