Commonly asked questions when calculating percentage eaten using this method. 6 A. Our goals and responsibility to the residents of long term care facilities Our goal and responsibility as care givers is to ensure that residents achieve highest levels of functioning possible (Quality of Care) and maintain their sense of individuality (Quality of Life).1 This should include meeting the nutritional needs of residents, as well as, maintaining their health and dignity which represents their quality of life. 4, 1 From a nutrition perspective this would mean that caregivers must ensure that residents maintain optimal food and fluid intakes while at the same time maintaining and/or preserving their lean muscle mass. B. Why is weight monitored and percentage eaten determined? 1. A major indicator of nutritional status is a resident’s weight history and/or changes. 2. Percentage of food eaten must be accurately determined in order to answer questions K4c (Leave 25% or more of food uneaten at most meals) and K6a (Code the proportion of total calories the resident received through parenteral or tube feeding in the last 7 days) on the Minimum Data Set Version 2.0, which is required to be completed in long term care facilities by the Omnibus Budget Reconciliation Act of 1987 (OBRA '87) 1 Questions found to be inaccurate when audited may impact reimbursement rates. To evaluate the effectiveness of nutrition intervention of a resident’s nutritional status, dietitians use information taken from food intakes in long-term-care settings. The Omnibus Senate Reconciliation Act of 1987 (OBRA) mandates that these figures be used when completing the Minimum Data Set. OBRA guidelines require a physical and health reassessment of a resident if he or she eats 75% or less of most meals. These records are also included in the governmental monitoring process used by state inspectors. 5 3. Monitoring meal consumption provides the quickest indicator or trigger to alert staff of a potential problem which may result in decreased nutritional status and/or weight. A study of 72 non-severely diseased elderly concluded that food intake is a strong predictor of survival even in moderately diseased elderly patients, suggesting possible low cost interventions. 2 Although the nutrient requirements of this population are not yet well understood, nutrition care is recognized as an important factor in improving longevity and quality of life. 1 7 4. Weight loss corresponds to increased morbidity and mortality. The first National Health & Nutrition Examination Survey found that female subjects from 45 to 74 had increased mortality with weight loss even if severely overweight; however, weight loss of 5% - 15% decreased mortality in severely overweight men (BMI >29).3 Those in institutional care are at a higher nutritional risk than others. Involuntary weight loss is damaging to the health and welfare of older people, especially those living in a nursing facility. 11, 3 Frail older adults are at an increased risk of developing malnutrition and its consequences. Even less frail older adults living in the community are at risk for poor nutrition with studies indicating three percent of men and six percent of women are underweight. 5. Weight fluctuation of 3+ pounds would indicate that the resident’s hydration status be considered.1 Dehydration especially in the elderly is associated with significant morbidity and mortality.4 A common problem in nursing homes is dehydration. It is associated with significant morbidity and mortality including a higher prevalence of pressure sores, delayed wound healing, and increased rates of infection. 2 C. What causes weight loss in older persons? A number of common causes are included in the mnemonic MEALS-ON-WHEELS 7 M edication effects E motional problems, especially depression A norexia nervosa, Alcoholism L ate-life paranoia S wallowing disorders O ral factors (e.g., poorly fitting dentures, caries) N o money (poverty) W andering and other dementia-related behavior H yperthyroidism, hypothyroidism, hyperparathyroidism, hypoadrenalism E Enteric problems E ating problems (e.g., inability to feed self) L ow-salt, low cholesterol diet S tones, social problems (e.g., isolation, inability to obtain preferred foods) Since factors which cause weight loss are SOCIAL, PSYCHOLOGICAL, MEDICAL, & AGE RELATED, it is critical for the entire interdisciplinary team to work together to help prevent weight loss. 8 D. What happens to a person’s body composition with weight loss then weight gain? 1. The percentage of the weight loss that is muscle versus fat will vary with the type of diet whether the loss was planned or unplanned. (Record this on flip chart to reference.) “Obese clients who lose weight due to a stress response typically lose lean body mass and retain their fat reserves. It is imperative to recognize that the energy and protein needs of stressed older adults are higher than those of healthy individuals.” 11 Percent of Weight Loss Lean Body Mass Fat 68 % 32 % Ketogenic Diets < 1000 Kcal/day 65 % 35 % Mixed Food Diets < 1000 Kcal/day 40 % 60 % Mixed Food Diets > 1000 Kcal/day 32 % 68 % Mixed Food Diets + Mild Exercise > 1000 Kcal/day 21 % 79 % Starvation OR Fasting 2. Weight gained back after initial loss will be a greater percentage of fat to lean than what was initially lost unless the weight gain is done in conjunction with high-intensity resistance training.6 This is why it is so critical for the interdisciplinary care team to prevent weight loss before it happens. “Various studies have demonstrated a strong correlation between weight loss and morbidity and mortality. One study showed that nursing home patients had a significantly higher mortality rate in the six months after losing 10 percent of their body weight, irrespective of diagnoses or cause of death.” 7 3. It is encouraging that older individuals both healthy and frail including those up to 100 years of age, have been shown to respond to high-intensity resistance training with both muscle hypertrophy and marked increases in strength. 7 Exercise can help make up for some of the adverse changes in body composition that can occur with aging. Resistive, weight-bearing aerobic exercise has shown to stabilize or increase bone mass in pre-and postmenopausal women and older men. 6 9 E. What is the effect of protein-energy undernutrition (weight loss) in older persons? (Record this on flip chart to reference.) Some effects include: 9 Anemia decreased cognition edema falls hip fractures immune dysfunction infections muscle loss osteoporosis pressure sores In institutionalized older adults, weight loss may be a result of both emotional and physical conditions. Increased mortality has been associated with unintentional weight loss and protein-energy malnutrition. Pressure ulcers and a decreased resistance to infection can also be seen with unintentional weight loss. 1 F. Prevention - An ounce of prevention is worth a pound of cure. 1. The effects of protein-calorie undernutrition translate into decreased ability of the elderly to accomplish their Activities of Daily Living (ADLs) which in turn creates increased work loads for the caregivers. Weight loss is usually detrimental not only for the older individual who experiences it, but also for the caregiver (due to increased work load, complexity of care, and cost.) 2. Once an elderly individual becomes malnourished, it takes more aggressive nutrition therapies to bring the nutritional status of the individual up than it does in younger individuals.8 Studies with older adults have shown that they are less likely to “make up” for inadequate food and fluid intake at one meal by eating more at later meals. 1 3. The quickest indicator of proper nutritional intake is to monitor percentage of meal consumption. For the consumption records to be an effective audit tool, they must accurately reflect actual food intake. Therefore, an easy to use system which provides consistent accurate results must be used to be effective and insure proper reimbursement. A study has shown the tray diagram or pie chart used by some facilities produced unreliable figures.9 One needs to estimate resident food intake in order to identify residents who are not eating well. 2 10 Monitoring the amount of food left on one’s plate can be a valuable tool to determine the actual amount of food consumed. Measuring reduced plate waste can help indicate the acceptability of food items offered and show the actual amount of food consumed, leading to menu modifications if necessary. 8, 10 4. Observed intake of less than 75% consumed as recorded on Dietary Intake Records requires more in-depth monitoring or assessment and review by the interdisciplinary care plan team. Substitutes for items not eaten should be offered when less than 75% of a meal is consumed. 5. Federal and state regulations may require recording consumptions for specific periods of time. G. How to accurately calculate percentage eaten using this method endorsed by Arkansas CD-HCF. (Copyright 1994 Nancy Storms-Walsh) 1. Count the number of servings on the tray (do not count garnishes, coffee, tea, water, condiments, milkshakes or canned supplements if they are not part of the planned menu). 2. Estimate the total servings eaten by adding up the amount eaten of each serving counted. Example: 1/2 meat + 1/4 starchy veg + 0 veg + 3/4 milk + 3/4 fruit + 1/2 bread = 2 3/4 servings eaten. 3. Round total servings eaten down to the nearest 1/2 serving. Example: 2 3/4 servings rounded down = 2 1/2 servings eaten 4. To change the total number of servings eaten to percentage eaten, you will need to refer to the “How To Calculate Percentage Eaten” chart or pocket reference cards from Arkansas CD-HCF. Find the total number of servings eaten (step 3) along the top of the chart. Locate the total number of servings counted (step 1) along the side of the chart. The point at which the rows intersect will note the percentage consumed. Example: 2 1/2 servings eaten / 6 total servings counted = 42% eaten. 5. Record the percentage eaten for each resident on the appropriate meal record form. 6. If a milkshake or canned supplement has been included on the meal Tray, but is not part of the diet as specified on the menu, the percentage consumption must be charted separately from the rest of the meal consumed. Documentation of snacks and supplements must always be recorded independent of the meals. 11 H. Commonly asked questions concerning how to calculate percentage eaten using this method. 1. How does one calculate for double portions of items served? What if the person calculating the percentage eaten is not aware that they were served double portions? Answer: One can only calculate the percentage eaten to the best of their knowledge. It is not a big concern because the double servings if counted for example as 1/2 serving eaten of 1 item counted or 1 serving eaten of 2 items counted will cause the percentage to vary only a few percentage points. This is still more accurate than “guessing." 2. What constitutes a “serving” of something? Answer: A good “rule of thumb” would be to cup your hands together. If the serving size looks as if it would almost fill your cupped hands (approx. 1/2 cup), it is counted as a serving. Example: 1 orange slice vs. 1/2 cup orange sections. The pureed consistency diets would be an exception to this. Example: 1 cup fresh lettuce salad will puree down to less than 1/4 cup. 3. How do I know if the milkshake or supplement on a resident’s tray is on the menu? Answer: If a food item is part of the menu, you would see all residents on that same diet receiving that particular item unless they had a dislike for it. Most facilities do not include milkshakes or supplements as part of the menu. When in doubt, it is best to ask the Dietary Manager or Dietitian. II.
