Goals and Importance of Nutritional Assessment Nutritional assessment in clinical medicine has three primary goals: to identify the presence and type of malnutrition, to define health-threatening obesity, and to devise suitable diets as prophylaxis against disease later in life.
What are the factors that determine nutritional assessment?
Correct interpretation of the results of nutritional assessment usually requires consideration of other factors, such as socioeconomic status, cultural practices, health and vital statistics (ecological; factors).
Why is nutrition assessment important?
Availability of reliable and precise information in this area shapes development in many ways: it enhances understanding of national nutritional scenarios, provides necessary tools for crafting and monitoring development interventions, and guides decision-makers towards improved planning and policy-making in matters of public health. Selecting the right assessment method depends on the specific objectives, context, and population of each study. However, all research projects must follow minimal quality-control criteria and harmonize their data-collection, analysis and presentation methods with internationally recognized standards in order to ensure comparability with the studies and surveys of other countries. This will undoubtedly redound to an improvement in the implementation of specific and sensitive nutrition programs, as well as to opportune decision-making.
Why are nutrition surveys used?
For example, nutrition surveys are used to assess the nutritional status of selected population to identify the group at risk for chronic malnutrition or for evaluation of the existing nutritional problems in order to formulate nutrition policies. In nutritional surveillance studies data are collected, analyzed, and evaluated on standardized method during longer period for identification of the possible nutritive risk factors for malnutrition for policy formulation of the whole population or specific vulnerable group or for evaluation and monitoring of the nutrition intervention. Nutrition screening is used for the identification of malnourished individuals and nutrition interventions are used for the population subgroups at risk ( Gibson, 2005 ).

Nutritional status represents meeting of human body needs for nutritive and protective substances and the reflection of these in physical, physiological, and biochemical characteristics, functional capability, and health status.
What is nutrition surveillance?
Nutrition surveillance – continuous monitoring of the nutritional status of selected population groups (e.g., at-risk groups) for an extended period of time; conducted to identify possible causes of malnutrition
What is a complete nutritional assessment?
A complete nutritional assessment generally is reserved for seriously ill patients, those at high nutritional risk, or individuals with signs of malnutrition. Clinicians may also perform a dietary assessment, which is less involved than a nutritional assessment, but helps ensure adequate nutrition by providing guidance for improving diet.
Why is a dietary assessment important?
A dietary assessment is often conducted to determine the macronutrient (energy or caloric, protein, carbohydrate, and fat) content and the micronutrient (vitamin and mineral) content of the diet to assist in guiding dietary counseling. Validation of dietary assessment instruments is important in order to accurately evaluate the diet for certain risk factors associated with chronic diseases such as diabetes. A dietary assessment is often used as a tool to help the patient lose weight or to prevent or treat conditions or diseases that are influenced by food intake and nutritional status (e.g., cardiovascular disease, obesity, diabetes, hyperlipidemia).
What is nutritional status?
Nutritional status is a more comprehensive term, referring to health status as it is affected by nutrition. It is measured not only by assessing dietary status, but also by anthropometric, biochemical, and clinical measures. Because dietary methods are less invasive, somewhat easier to obtain than other physiological measures, and do not require medical training, they often are used initially for assessing nutritional inadequacy or excess. Physiological measurements are then used to confirm and corroborate dietary intake evaluation and to arrive at definitive assessments of nutritional status.
How to document dietary intake?
During a nutrition interview the practitioner may ask what the individual ate during the previous twenty-four hours, beginning with the last item eaten prior to the interview. Practitioners can train individuals on completing a food diary, and they can request that the record be kept for either three days or one week. Documentation should include portion sizes and how the food was prepared. Brand names or the restaurant where the food was eaten can assist in assessing the details of the intake. Estimating portion sizes is difficult, and requesting that every food be measured or weighed is time-consuming and can be impractical. Food models and photographs of foods are therefore used to assist in recalling the portion size of the food. In a metabolic study, where accuracy in the quantity of what was eaten is imperative, the researcher may ask the individual to prepare double portions of everything that is eaten — one portion to be eaten, one portion to be saved (under refrigeration, if needed) so the researcher can weigh or measure the quantity and document the method of preparation.
How to measure body fat?
To estimate body fat, skinfold measurements can be made using skin-fold calipers. Most frequently, tricep and subscapular (shoulder blade) skin-folds are measured. Measurements can then be compared to reference data — and to previous measurements of the individual, if available. Accurate measuring takes practice, and comparison measurements are most reliable if done by the same technician each time.
What is a dietitian?
Dietitian —A dietitian is a health professional who has a bachelor's degree, specializing in foods and nutrition, and undergoes a period of practical training in a hospital or community setting. Many dietitians further their knowledge by pursuing master's or doctoral degrees. The title "dietitian" is protected by law so that only qualified practitioners who have met education qualifications can use that title.
What is the role of a physician in nutrition?
Physicians are responsible for assessing, diagnosing, and treating conditions associated with or contributing to poor nutrition status, and working with registered dietitians to develop a nutrition care plan. Registered dietitians provide medical nutrition therapy to patients and tailor the therapy to individual patient needs. They also advise patients, family, and other caregivers on medical nutrition.

What is nutritional risk screening?
Nutritional risk screening tools are very helpful in the daily routine to detect potential or manifest malnutrition in a timely manner. Such tools should be easy to use, quick, economical, standardized, and validated. Screening tools should be both sensitive and specific, and if possible, predictors of the success of the nutritional therapy. Nutritional screening should be part of a defined clinical protocol that results in a plan of action if the screening result is positive.
Who should be the nutritional care plan for a patient with malnutrition?
When malnutrition is diagnosed, an individual nutritional care plan should be established by a nutrition specialist (e.g., dietitian, expert clinician) in consultation with a multidisciplinary team, and monitored regularly throughout the hospital stay.
How many people are malnourished in hospital?
For various reasons, ill people may struggle to meet their nutritional and hydration requirements, and as a consequence, 20–50% of patients are malnourished or at high risk of malnutrition upon hospital admission [1]. One in five patients does not consume enough food to cover their energy or protein needs [2].
What is the risk of malnutrition?
Malnutrition is an independent risk factor that negatively influences patients’ clinical outcomes, quality of life, body function, and autonomy. Early identification of patients at risk of malnutrition or who are malnourished is crucial in order to start a timely and adequate nutritional support.
Why is nutrition important?
Nutrition is a basic need of life and thus plays an important role in health promotion and disease prevention. Nutritional intake and its controlling mechanisms (e.g., appetite, satiety) are highly complex physiological processes. These processes have a strong influence on nutritional status, which in turn depends on nutritional intake, its balanced supply of macro and micronutrients, and fluid intake. For various reasons, ill people may struggle to meet their nutritional and hydration requirements, and as a consequence, 20–50% of patients are malnourished or at high risk of malnutrition upon hospital admission [1]. One in five patients does not consume enough food to cover their energy or protein needs [2]. The underlying disease may directly impair nutritional intake and may induce metabolic and/or psychological disorders, which increase the nutritional needs or decrease food intake [3,4,5]. Frequent problems such as chewing and swallowing issues, immobility, and side effects of drugs and polypharmacy should not be underestimated in this regard [6,7]. A protracted decline in nutritional status results in a catabolic metabolism and chronic low-grade inflammation, potentially leading to several harmful consequences, such as loss of fat-free mass, immune dysfunction, higher complications and mortality rates, reduced quality of life, and prolonged hospital stays [8,9]. Malnutrition also influences the efficacy or tolerance of several treatments, such as antibiotic therapy, chemotherapy, radiotherapy, and surgery. The increased metabolism due to the stress of eventual surgical procedures further aggravates the nutritional metabolic risk, and is characterized by activation of the sympathetic nervous system, endocrine responses, and immunological and hematological changes—all leading to a hypermetabolic state, which may further increase patients’ nutritional needs. In addition, the fasting periods before many examinations and interventions, as well as inappropriate meal services, inadequate quality and flexibility of hospital catering, and insufficient assistance provided by the health care staff to the most vulnerable patients, lead to further inadequate food intake and deterioration of patients’ nutritional status.
How long does an acute illness last with reduced food intake?
Acute illness with reduced food intake (estimated) for ≥5 days
When should nutritional screening be performed?
Screening should be performed within the first 24–48 h after hospital admission and at regular intervals thereafter (e.g., weekly), in order to rapidly and accurately identify individuals who should be referred to the nutrition specialist (e.g., dietitian, expert clinician) for further assessment. Nutritional screening should include dynamic parameters rather than static ones—for example, recent weight loss, current body mass index (BMI), recent food intake, and disease severity. According to the systematic review conducted by van Bokhorst-de van der Schueren et al., at least 33 different nutritional risk screening tools exist [19]. The present work will use three as examples. The present work will use three examples thereof, which the European Society for Clinical Nutrition and Metabolism (ESPEN) recommends: the Nutritional Risk Screening 2002 (NRS-2002) for the inpatient setting, the Malnutrition Universal Screening Tool (MUST) for the ambulatory setting and the Mini Nutritional Assessment (MNA) for institutionalized geriatric patients [20].
What is nutritional screening?
Nutritional screening is a first-line process of identifying patients who are already malnourished or at risk of becoming so; nutritional assessment is a detailed investigation to identify and quantify specific nutritional problems (Bond, 1997). Nutritional screening is usually undertaken by nurses and doctors; assessment by dietitians.
Why is nutrition important?
Good nutrition is fundamental for health, healing and recovery from illness and injury. Malnutrition is associated with muscle wasting, impaired respiratory and cardiac function, decreased mobility (Lennard-Jones, 1992); susceptibility to infection and delayed wound healing (Chandra, 1990; Windsor et al, 1988); depression and lethargy (Brozek, (1990). Hospital complications, mortality and unplanned readmission rates rise, inpatient treatment is prolonged (Robinson et al, 1987; Sullivan, 1992). Many factors including disease predispose to malnourishment and indicators of malnutrition are found in up to 40% of patients admitted to hospital and a significant proportion of community patients (McWhirter and Pennington, 1994; Edington et al 1996). Screening, by identifying patients and clients with problems or at risk of developing them, is the essential first step of management.
How to calculate BMI?
The most commonly used calculation is Quetelet’s Index (usually referred to as BMI) which is weight (kg) divided by height (m 2 ). For example, someone of height 1.7m (5ft 8in) weighing 73kg has a BMI of 73/ (1.7 2 = 2.89) = 25.3kg/m 2. Charts to look this up are available (Fig 1). There is limited consensus over cut-off values with below 20kg/m 2 often regarded as suggestive of nutritional risk and less than 18kg/m 2 indicative of nutritional compromise; in older people criteria may be higher (Beck and Ovesen, 1998) (e.g. less than 23kg/m 2 ).
Why are sequential weights recorded?
Sequential weights can be recorded to track progress/ response to nutrition support.
Is weight a nutritional index?
Weight has limitations as a nutritional index. Equipment may not be available to weigh immobile patients and for accuracy scales require regular servicing and calibration; many do not receive this (Chu et al, 1999). Shifting fluid balance with dehydration and oedema, differing scales, clothing and times of day for weighing may mean that changes do not reflect nutritional state. Weight measurement cannot differentiate muscle from fat and does not take account of overall bodily size.
Is nutritional screening important?
While nutritional screening is an essential first step, other factors may also need to be considered, for example, screening swallowing function in neurological diseases including stroke (Perry, 2001; Stroke Research Unit, www.ncl.ac.uk/stroke-research-unit/coda/cointro.htm .).
Is albumin a good nutritional indicator?
Albumin has a long half-life and is a particularly poor nutritional index, although it may indicate prognosis as it can reflect severity of illness.
