Association between Body Mass Index and Hospital Outcomes for COVID-19 Patients: A Nationwide Study. J Clin Med 2023; 12:jcm12041617. [PMID: 36836153 PMCID: PMC9967784 DOI: 10.3390/jcm12041617] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 02/15/2023] [Accepted: 02/15/2023] [Indexed: 02/22/2023] Open
Abstract
BACKGROUND Coronavirus disease 2019 (COVID-19) caused significant morbidity and mortality worldwide. There is limited information describing the hospital outcomes of COVID-19 patients in regard to specific body mass index (BMI) categories. METHODS We utilized the Healthcare Cost and Utilization Project Nationwide Inpatient Sample (NIS) 2020 database to collect information on patients hospitalized for COVID-19 in the United States. Using the International Classification of Diseases, 10th revision, Clinical Modification (ICD-10-CM) coding system, adult patients (≥18 years of age) with a primary hospitalization for COVID-19 were identified. Adjusted analyses were performed to assess for mortality, morbidity, and resource utilization, and compare the outcomes among patients categorized according to BMI. RESULTS A total of 305,284 patients were included in this study. Of them, 248,490 had underlying obesity, defined as BMI ≥ 30. The oldest patients were observed to have BMI < 19, while youngest patients were in the BMI > 50 category. BMI < 19 category had the highest crude in-hospital mortality rate. However, after adjusted regression, patients with BMI > 50 (adjusted odds ratio (aOR) 1.63, 95% CI 1.48-1.79, p-value < 0.001) had the highest increased odds, at 63%, of in-hospital mortality compared to all other patients in the study. Patients with BMI > 50 also had the highest increased odds of needing invasive mechanical ventilation (IMV) and mortality associated with IMV compared to all other patient, by 37% and 61%, respectively. Obese patients were noted to have shorter average hospital length of stay (LOS), by 1.07 days, compared to non-obese patients, but there was no significant difference in average hospitalization charges. CONCLUSION Among obese patients primarily hospitalized with COVID-19, those with BMI ≥ 40 had significantly increased rates of all-cause in-hospital mortality, need for IMV, mortality associated with IMV, and septic shock. Overall, obese patients had shorter average hospital LOS, however, did not have significantly higher hospitalization charges.

Abstract
BACKGROUND & AIMS CPGs propose several methods and criteria to perform nutritional assessment, a key process to determine the type and severity of malnutrition, which generates variability in clinical practice and outcomes. The aim of the study was to describe the criteria considered by clinical practice guidelines (CPGs) for nutritional assessment. METHODS We performed a scoping review systematically searching in PubMed, Trip Database, Google Scholar, and Google, until November 5, 2021. We included all CPGs mentioning tools or criteria for nutritional assessment in adults from the general population or with any specific pathology or condition. Two authors independently reviewed and decided on study selection and data extraction. RESULTS We included 18 CPGs (12 elaborated in Europe). The CPGs recommended heterogeneous criteria for nutritional assessment: 16/18 CPGs included at least one body composition parameter (e.g., loss of muscle mass, loss of subcutaneous fat), 15/18 included history related to dietary intake, 15/18 included clinical history (e.g., weight loss), 10/18 included anthropometric measurement (e.g., low body mass index [BMI]), 11/18 included biochemical criteria (e.g., albumin, C-reactive protein), 8/18 included physical examination (e.g., fluid retention, sarcopenia, loss of subcutaneous fat), 8/18 included functional test (e.g., decreased handgrip strength), and 1/18 included catabolic state. Also, 9/18 CPGs mentioned a tool for nutritional assessment, the Subjective Global Assessment (SGA) the most common (8/18). None of the CPGs justified the inclusion of any of the tools or criteria they mentioned. CONCLUSIONS The CPGs mentioned heterogeneous criteria for nutritional assessment. The most commonly mentioned criteria were decreased food intake, loss of muscle mass, weight loss, and low BMI. The most mentioned tool was the SGA. None of the CPGs provided a clear rationale for using certain criteria or tools for nutritional assessment.

Abstract
BACKGROUND UK NICE guidelines, state that patients attending an outpatient clinic for the first time, should be screened for malnutrition. AIMS To determine the prevalence of malnutrition in the medical and surgical gastroenterology outpatient department (OPD) using body mass index (BMI) and % weight loss (%WL) and to assess the physicians'/surgeons' response to malnutrition being detected. METHODS The BMI and the %WL were determined for every patient over a 2 week period before the clinician saw the patient. The BMI and %WL were scored as in the Malnutrition Universal Screening Tool (MUST). RESULTS 605 patients (316 females) of mean age 54 years were included. 150 (25%) were new patients. 519 (86%) had a normal BMI and %WL. 86 (14%) had a BMI <20 kg/m2 or had 5% WL. 61 (10%) were in MUST "medium risk" and 25 (4%) were in MUST "high risk" of malnutrition. 15 (60%) of the "high risk" patients were under the care of or had been referred to a dietitian compared to 19 (28%) of "medium risk" patients. The prevalence of malnutrition was independent of sex, age, history of previous surgery or underlying comorbidities. There was no difference in the prevalence of malnutrition between new and follow up patients. Malnutrition was more common in patients with IBD (38, 18%) vs non-IBD (48, 12%) and patients with cancer (11, 25%) vs non cancer (75, 13%) (p < 0.05). CONCLUSIONS The prevalence of malnutrition in medical and surgical gastrointestinal outpatients was 14%. IBD and cancer patients had the highest prevalence. Most patients with malnutrition (52, 61%) were not being seen by a dietitian.

Abstract
Screening and assessment imply different processes, with the former indicating risk factors for a deprived nutrition condition and the latter providing the nutrition diagnosis. Both should be routinely performed at hospital admission according to recommended guidelines; however, this is not the reality worldwide, and undernutrition remains highly prevalent in the hospital setting. Therefore, the objective of the current review is to delve into the principles leading to nutrition status deficiencies and how they should be addressed by screening and assessment. A critical appraisal for the reasons associated with the misunderstanding between screening and assessing is proposed without further discussing the many available screening tools while approaching some of the assessment instruments.

Abstract
BMI is commonly used indicator of malnutrition and 18.5-24.9 kg/m(2) is generally regarded optimal. However, there is an ongoing debate on ideal range for elderly. BMI cut-off values vary also between ethnic groups. We aimed to investigate relationships between BMI, functional status and malnutrition in elderly living in a nursing home in Turkey. BMIs of 254 residents were calculated. Chronic diseases and currently used drugs were noted. Functional status was evaluated with Katz-activities-of-daily-living (ADL) and Lawton-instrumental-activities-of-daily-living (IADL). Nutritional assessment was performed by Mini-Nutritional-Assessment (MNA) test. Mean age was 75.2 ± 8.2 years. Subjects were classified into 4 groups as BMI <18.5, 18.5-24.9, 25-29.9, and ≥ 30.0 kg/m(2). ADL scores and IADL scores were higher in higher BMI groups. There were no differences in terms of age-number of chronic diseases. Even in BMI ≥ 35 kg/m(2) residents, ADL was significantly higher than 25-34.9 kg/m(2) residents. BMI was significantly correlated with ADL and IADL scores. In Groups 3 and 4, there were 22.2% and 9.1% residents without normal nutrition, respectively. Better functional status was associated with higher BMI values even in BMIs ≥ 30 kg/m(2). In elderly, relative high rates of undernutrition may be present in BMIs regarded as overweight or obese.

Abstract
Undernutrition in hospitalized older adults is increasingly being recognized as a serious problem with implications for both patient care and outcomes and health service utilization and costs. This article presents an overview of research that has been conducted examining undernutrition in hospitalized older adults. First, findings from observational studies examining patterns and predictors of undernutrition in hospitalized older adults will be described, with a focus on methodological challenges. Second, clinical outcomes and costs associated with undernutrition in hospitalized older adults will be presented, both while in the hospital and subsequent to discharge. Third, a description of interventions that have already been implemented in hospitalized older adults will be described. Finally, future areas of inquiry and opportunities for evidence-based nutritional interventions targeted at older adults during and following hospitalization will be suggested. The emphasis of the discussion on interventions will focus on processes of care and the hospital environment.

Abstract
AIM Accurate assessment of nutritional status is a vital aspect of caring for individuals with anorexia nervosa (AN) and body mass index (BMI) is considered an appropriate and easy to use tool. Because of the intense fear of weight gain, some individuals may attempt to mislead the physician. Mid-upper arm circumference (MUAC) is a simple, objective method of assessing nutritional status. The setting is an eating disorders clinic in a tertiary paediatric hospital in Western Australia. The aim of this study is to evaluate how well MUAC correlates with BMI in adolescents with AN. METHODS Prospective observational study to evaluate nutritional status in adolescents with AN. RESULTS Fifty-five adolescents aged 12-17 years with AN were assessed between January 1, 2004 and January 1, 2006. MUAC was highly correlated with BMI (r = 0.79, P < 0.001) and individuals with MUAC >or=20 cm rarely required hospitalisation (negative predictive value 93%). CONCLUSIONS MUAC reflects nutritional status as defined by BMI in adolescents with AN. Lack of consistency between longitudinal measurements of BMI and MUAC should be viewed suspiciously and prompt a more detailed nutritional assessment.

Abstract
In recent years there has been a proliferation of nutrition screening tools but undernutrition remains prevalent amongst older subjects. Screening tools commonly include BMI as the widely-accepted ‘gold standard’ indicator of malnutrition. Whilst BMI may be an appropriate tool for population studies when it can be measured accurately in research conditions, the use of BMI in clinical practice may mask important weight changes and result in a failure to alert healthcare staff to a nutritional problem. The inclusion of BMI has been identified as a barrier to completing the screening process at ward level. Also, feedback from dietitians working with older subjects indicates that 72.5% of those using BMI express concerns that it is of limited use for practical reasons or that the reference range (20–25 kg/m2) is not appropriate to older subjects. Further evidence questions whether or not BMI is applicable for inclusion in methods used to identify an older subject at risk of undernutrition in a variety of care settings. In view of these findings it is advocated that weight change over a period of time together with clinical judgement is a far superior prognostic indicator of undernutrition. Despite screening, there is evidence that inpatients continue to lose weight before discharge. Further experiential evidence from both community and ward settings suggests that inadequacies in care planning, food provision and a lack of assistance with feeding are common. In order to improve the management of undernutrition in older subjects it is therefore recommended that the focus of attention should be on addressing these practical issues and on the effective monitoring of these processes.

Abstract
OBJECTIVES A hospital-based nutrition support team (NST) may need to demonstrate cost savings and quality benefits. The primary aim of this study was to determine whether an NST could show tangible cost savings (equipment, investigations, and medication costs) from managing patients considered for parenteral nutrition (PN). Secondary aims related to the quality issues of placement of PN catheters, catheter-related sepsis (CRS), duration of parenteral nutrition, and mortality. METHODS An NST was formed in 1999 and worked in all adult areas of a university hospital (Leicester Royal Infirmary). Comparative data about all patients given PN were collected for 2 consecutive years (a retrospective pre-NST year and a prospective NST year). RESULTS In the pre-NST year there were 82 PN episodes (54 patients), 665 PN days, and a CRS rate of 71% (seven infections/100 PN days). In the NST year, there were 133 referrals for PN but only 78 PN episodes (75 patients, 59% of referrals), 752 PN days, and a decreased overall CRS rate of 29% (three infections/100 PN days, P < 0.05) but a rate of 7% (0.6 infection/100 PN days) in the final 3 mo of the NST year. Tangible cost savings for the NST year were derived from 55 avoided PN episodes (42741 pounds sterlings) and 35 avoided CRS episodes (7974 pounds sterlings). Thirty-nine percent of PN catheters were inserted by the NST with no insertion-related complications. Competency-based training of ward nursing staff decreased the CRS rate. Mean duration of PN increased from 8 to 10 d (P not significant). In-hospital mortality for patients who had PN was 23 of 54 (43%) in the pre-NST year compared with 18 of 75 (24%) in the NST year (P < 0.05). CONCLUSIONS Although the number of PN days increased with an NST, tangible cost savings of 50715 pounds sterlings were demonstrated within the NST year by avoided PN episodes and a decreased incidence of CRS. These savings justify the salaries of a nutrition nurse specialist and a senior dietitian.

Abstract
BACKGROUND Dehospitalization is a trend in the health sector justified by humanitarian and socials aspects for the patient and relatives. From the financing institutions' perspective, whether government or third party, the positive results arise from an optimization of hospital bed use and favorable cost-benefit ratio. The "integrated home-hospital" model was created with the purpose of optimization of resources without detriment to the patients' nutritional care. The objective of this study was an economic evaluation regarding nutrition therapy of the integrated hospital-home model in comparison with an exclusively hospital model. METHODS A retrospective controlled study, paired (age, sex, disease, and surgical procedure), was performed on 56 digestive surgery patients divided into 2 groups: study (SG; n = 30) and control (CG; n = 26). The data collected included total expenses with hospitalization, nutritional benefits, minimization cost analysis, cost-effectiveness ratio analysis, cost-benefit ratio analysis, hospital length of stay, and hospital-bed optimization. RESULTS The patients from the SG achieved the same nutritional benefits as those in the CG, but with expenses 3 times lower (median Brazil Reals (R)$3237.18 vs R$8647.93; p < .05). The new model resulted in economic benefit to the institution, as shown by the cost-effectiveness ratio, mainly resulting from the savings of the days of hospitalization avoided. The cost-benefit ratio showed an important savings per patient for the institution (US $3100). CONCLUSIONS The home-hospital model also reduced length of hospital stay 2.7 times and optimized the hospital bed usage, as it promoted higher hospital-bed rotation (3 times greater).

Abstract
BACKGROUND & AIMS We have estimated the prevalence of severe malnutrition in groups of patients hospitalized for different medical causes and assessed the sensitivity of BMI in the diagnosis of severe malnutrition. DESIGN A prospective study enrolled 1052 patients: 396 patients with liver cirrhosis including 165 non-ascitic patients (NAP), 124 patients with mild ascites (MAP), 107 patients with tense ascites (TAP), 251 patients after cardiac surgery (SCP), 81 patients with cardiac diseases (MCP), 85 patients with stroke (SP), 36 patients with degenerative neurological diseases (DNP), 68 patients after surgery of a hip fracture (HFP), 91 patients with palliative care for cancer (CP) and 44 elderly patients with medical affections (EP). BMI, mid-arm muscular circumference (MAMC) and triceps skinfold thickness (TST) were measured within 48 h after admission. Patients with MAMC and TST below the 5th percentile of a reference population when aged < or = 74 or the 10th percentile when aged > or = 75 were defined as severely malnourished. Sensitivity of BMI < 20 to detect malnutrition was assessed. RESULTS The prevalence of severe malnutrition was the highest in TAP (39.1%) HFP (25.6%) and MAP (24.3%) and the lowest in SCP (4%), SP (4.8%), DNP (5.7%) and MCP (7.4%) (P < 10(-4)). In multivariate analysis, low TST was associated with female gender (P < 10(-4)) mild and tense ascites (P = 0.038, P = 0.0004), low MAMC with male gender (P < 10(-4)), low BMI with female gender (P = 0.0082), hip fracture (P = 0.0407) and cancer (P = 0.0059). The sensitivity of BMI to detect severe malnutrition was the highest in HFP, CP and EP (100%, 80% and 100% respectively) and the lowest in TAP, MCP and SP (40%, 33.3% and 50% respectively). After exclusion of TAP, sensitivity of BMI to detect malnutrition correlated significantly with the coefficient of correlation between MAMC and TST observed in each group (r = 0.821, P = 0.0066). CONCLUSION Ascitic cirrhotic patients and elderly patients after surgery of hip fracture had the highest prevalence of severe malnutrition. BMI had the highest sensitivity when both TST and MAMC were damaged to the same extent. BMI < 20 has a high sensitivity in the diagnosis of severe malnutrition in elderly and cancer patients but not in cirrhotic patients with tense ascites, cardiovascular and neurological patients.

Abstract
PURPOSE OF REVIEW This review will discuss the financial cost of the decisions taken regarding the nutritional therapy of hospitalized patients compared with those treated at home. To facilitate comprehension, the authors present a concise introduction to the general concepts of economic health studies, including a glossary of technical terms. RECENT FINDINGS From a revision of the literature, economic aspects are underscored involving the cost of malnutrition, the maintenance of work in a nutritional support team, the use of nutritional therapy in home-care programmes, and in the use of nutritional therapy as a prophylactic action against surgical complications. SUMMARY Hospital malnutrition burdens the system financially by provoking a higher rate of surgical complications, mortality and longer hospital stays. Investment in nutritional therapy provides economic returns. The cost of the creation and maintenance of the nutritional support team is easily offset by the resources generated by the team itself. Nutritional therapy in home-care is highly advantageous. In Brazilian trials, groups of surgical patients receiving nutritional therapy within the integrated hospital-home model demonstrated a cost 2.6 times less than the conventional group (exclusively intra-hospital treatment). The adoption of preoperative immunomodulatory nutritional therapy in patients undergoing elective surgery as a prophylactic against postoperative surgical complications presented a 2.24 times reduction in the total treatment cost. The search for the ideal model of nutritional therapy is based on the binomial of quality and cost. The prescription of nutritional therapy has a favourable impact on financial and resource-generating aspects of the institution, when practised by properly trained groups.

Abstract
PURPOSE OF REVIEW Malnutrition is highly prevalent in hospitalized patients. Despite this, it is not routinely assessed in most hospitals worldwide. One of the reasons that might explain this fact is that there is no gold-standard nutritional assessment tool, and much has been written advocating this or that technique. The main topic of this review is discussion of the advantages and disadvantages of each of the available tools. RECENT FINDINGS Several studies have recently reinforced the relationship between poor nutritional status and higher incidences of complications, mortality, length of hospital stay and costs. Therefore, it is of the utmost importance to be able to diagnose malnutrition early. SUMMARY The evaluation of nutritional status is a broad topic that encompasses several clinical variables. In order to be ideal, the method should be able to predict patient outcome, should be able to be performed by most care-givers, should be inexpensive, and should not be time-consuming. Unfortunately, most nutritional assessment instruments were published with insufficient details regarding their intended use and method of derivation, and with an inadequate assessment of their effectiveness. Therefore, health professionals should be critical when defining which instrument should be adopted by an institution, and several factors should be taken into consideration.

Abstract
SUMMARY The outcomes of feeding training are typically evaluated in terms of feeding skills and swallowing abilities rather than the ultimate goal of feeding, namely, adequate nutritional status. To increase occupational therapy practitioners' awareness of nutritional status as an outcome of feeding training, a systematic review of the research literature was conducted to examine the relationship between nutritional status and self-feeding skills in people with dementia. Studies were evaluated by the strength of their evidence and analyzed to determine the relationships among dementia, nutritional status, and the ability to feed one's self. Results revealed that although nutritional status in people with dementia is variable, there is a tendency for lower body weight, lower measures of body composition, and lower body mass indexes in persons with dementia compared to those with no cognitive impairment. Individuals who feed themselves tend to weigh more compared to those who need assistance for feeding. There is also evidence to support that as feeding status improves or declines, body weight similarly increases or decreases.

Abstract
There are two common types of adult patient with a short bowel, those with jejunum in continuity with a functioning colon and those with a jejunostomy. Both groups have potential problems of undernutrition, but this is a greater problem in those without a colon, as they do not derive energy from anaerobic bacterial fermentation of carbohydrate to short chain fatty acids in the colon. Patients with a jejunostomy have major problems of dehydration, sodium and magnesium depletion all due to a large volume of stomal output. Both types of patient have lost at least 60 cm of terminal ileum and so will become deficient of vitamin B12. Both groups have a high prevalence of gallstones (45%) resulting from periods of biliary stasis. Patients with a retained colon have a 25% chance of developing calcium oxalate renal stones and they may have problems with D (-) lactic acidosis. The survival of patients with a short bowel, even if they need long-term parenteral nutrition, is good.

Abstract
BACKGROUND The aim of this study was to validate a nutrition screening tool for use in South Manchester University Hospitals Trust. METHOD A sample of 100 patients was selected from medical, surgical and elderly care wards. To test the reliability of the screening tool, nurses and dietitians completed the screening tool on the same patient. These results were compared for interobserver error to determine whether the screening tool was reproducible with different observers. To ascertain if the screening tool identified malnutrition at ward level, four markers commonly used to assess nutritional status were collected. These included body mass index (BMI), mid upper arm circumference MUAC, percentage weight loss, and energy intake calculated from the patient's first full day in hospital and expressed as a percentage of their estimated average requirements (EAR). RESULTS There was a 95% level of agreement between nurses and dietitians within +/-3. The screening tool had a sensitivity level of 78% and a specificity of 52% when compared to all patients who had one or more markers indicating malnutrition. This association was found to be statistically significant (P < 0.005). CONCLUSION The screening tool is reliable when completed by different observers and is valid for wide scale nutritional assessment. The screening tool identifies an acceptable number of patients who are malnourished but overestimates patients at moderate risk.

Abstract
OBJECTIVE We assessed nutrition status and prevalence of malnutrition in hospital patients as determined by the Subjective Global Assessment Form, awareness of patients' nutrition status by health teams, and the use of nutrition therapy. METHODS We enrolled 4000 hospital patients at least 18 y old who were covered by the Brazilian public health care system in a cross-sectional, multicenter epidemiologic study. We used Student's t and chi-square tests for univariate and multiple logistic regression analyses. RESULTS Malnutrition was present in 48.1% of patients and severe malnutrition was present in 12.5% of patients. The prevalence of malnutrition was higher in the northern and northeastern regions of Brazil, where per-capita income is lower. Malnutrition correlated with primary diagnosis at admission, age (60 y), presence of cancer or infection, and longer hospital stay (P < 0.05). Fewer than 18.8% of patients' records contained information on nutrition-related issues. Nutrition therapy was used in 7.3% of patients (6.1% enteral nutrition and 1.2% parenteral nutrition). CONCLUSIONS The prevalence of malnutrition in hospitalized patients in Brazil is high, physician awareness of malnutrition is low, and nutrition therapy is underprescribed.

Abstract
Adequate nutrition is critical during long-term spaceflight, as is the ability to easily monitor dietary intake. A comprehensive nutritional status assessment profile was designed for use before, during and after flight. It included assessment of both dietary intake and biochemical markers of nutritional status. A spaceflight food-frequency questionnaire (FFQ) was developed to evaluate intake of key nutrients during spaceflight. The nutritional status assessment protocol was evaluated during two ground-based closed-chamber studies (60 and 91 d; n = 4/study), and was implemented for two astronauts during 4-mo stays on the Mir space station. Ground-based studies indicated that the FFQ, administered daily or weekly, adequately estimated intake of key nutrients. Chamber subjects maintained prechamber energy intake and body weight. Astronauts tended to eat 40--50% of WHO-predicted energy requirements, and lost >10% of preflight body mass. Serum ferritin levels were lower after the chamber stays, despite adequate iron intake. Red blood cell folate concentrations were increased after the chamber studies. Vitamin D stores were decreased by > 40% on chamber egress and after spaceflight. Mir crew members had decreased levels of most nutritional indices, but these are difficult to interpret given the insufficient energy intake and loss of body mass. Spaceflight food systems can provide adequate intake of macronutrients, although, as expected, micronutrient intake is a concern for any closed or semiclosed food system. These data demonstrate the utility and importance of nutritional status assessment during spaceflight and of the FFQ during extended-duration spaceflight.

Abstract
BACKGROUND It is well documented that malnourished and/or obese surgical patients have increased morbidity and mortality post-operatively. Only a few studies investigating the effect of nutritional status on mortality are available pertaining to the transplant population. Since limited data are available on the nutritional status and its effects on mortality in the lung transplant population, we sought to ascertain whether there is an association between mortality and preoperative nutritional status. METHODS We examined mortality during the first 3 months after transplantation. Patients were grouped by body mass index (BMI) categories as < 17 kg/m(2), 17 to < 20 kg/m(2), 20 to 25 kg/m(2) (reference group), > 25 to 27 kg/m(2), and > 27 kg/m(2). Additional risk factors retrieved from the pre-transplant records included age, gender, diagnosis, energy requirements, protein requirements, protein and caloric intake, and weight history. Logistic regression for univariate and multivariate analysis for mortality used recipient age, gender, disease category, pre-transplant cytomegalovirus (CMV) serology, transplant type (single or bilateral), and donor age, gender, and CMV serology. RESULTS The likelihood estimates or odds ratios (ORs) of the risk of death within 90 days of lung transplantation for the BMI categories compared to the reference group were 3.7 for BMI < 17 kg/m(2) (p = 0.085), 1.6 for BMI < 17 to 20 kg/m(2) (p = 0.455), 3.5 for BMI > 25 to 27 kg/m(2) (p = 0.069), and 5.0 for BMI > 27 kg/m(2) (p = 0.003). CONCLUSIONS In patients with a pre-transplant BMI < 17 kg/m(2) or > 25 kg/m(2) the risk of dying within 90 days post-transplant was increased. In patients with a pre-transplant BMI of > 27 kg/m(2) the risk was significantly higher in than the reference group.

Abstract
Nutritional risk and its predictors were assessed by evaluating longitudinal changes in body weight using data collected from elderly community-dwelling and institutionalized Canadians who participated in both phases of the Canadian Study of Health and Aging, CSHA (n = 10,263). Change in body weight (% initial weight) was examined over a 5-year interval in 584 community and 237 institutionalized participants, and its predictors tested in multiple and logistic regression analyses. Average weight at CSHA-2 was 97% of initial weight at CSHA-1. Values were lower in those over 90 years and the demented. Increasing frailty in a 7-point scale (beta = -1.23, p = 0.04) predicted weight loss in institutional participants, as did difficulty in eating unaided (beta = 4.24, p < 0.001) and reported loss of interest in life (beta = 2.22, p < 0.001) among community subjects. Some 16% in institutions and 9% in the community were at moderate/severe nutritional risk, disproportionately represented by the oldest subjects and the demented. These analyses support the importance of assessing dietary intakes, anthropometrics, well-being and environmental predictors of aging in the elderly.

Abstract
Impaired nutritional status has been frequently reported in surveys estimating its prevalence amongst patients in hospital. While there is no doubt that protein-energy undernutrition has serious implications for health, recovery from illness or surgery and hospital costs, lack of nationally or internationally accepted cut-off points and guidelines for most nutrition-related variables make nutritional assessment difficult and proper comparisons between studies impossible. In reviewing published work in which the prevalence of undernutrition has been assessed, it can be seen that each study defined undernutrition, or nutritional risk, using different methodology. This present review aims to highlight the problems which arise when deciphering these studies, and the resulting difficulty in determining the true prevalence of undernutrition and nutritional risk, amongst both general and specific groups of hospital in-patients. It is widely agreed that routine hospital practices can further adversely affect the nutritional status of sick patients in hospital. How this occurs, and the potential effects of impaired nutritional status on clinical outcome are examined. The methods currently available to assess nutritional status are evaluated in the knowledge that such assessments are difficult in clinical practice. The review concludes by proposing that if we want the medical and nursing professions to consider the nutritional status of hospital patients seriously, definitions of undernutrition and nutritional risk, and cut-off values for the nutritional variables measured must be agreed to allow evidence-based practice. Outcome measures which allow clear comparisons between groups and treatments must be used in studies assessing the effects of nutritional interventions.

Abstract
BACKGROUND & AIMS The detection, prevention and treatment of undernutrition in hospitals is often poor. This study assesses the knowledge about undernutrition of staff in a UK teaching hospital. METHODS Twenty nine doctors, 65 final year medical students, 45 nurses, 11 dietitians, and 11 pharmacists anonymously completed a questionnaire of 20 multiple choice questions. One of five possible answers was considered correct. Twelve questions were about adult nutritional assessment and requirements, five about oral/enteral nutrition and three about parenteral nutrition. RESULTS Dietitians scored significantly more (median 16) than the other groups (doctors: seven, medical students: eight, nurses: seven and pharmacists: nine) (P < 0.0001). Medical students scored more than doctors (P < 0.001). Examples of areas in which knowledge could be improved are: 67% respondents thought the prevalence of hospital undernutrition to be less than 30%. While 91% of respondents correctly chose a well 70 kg man to need about 2000 kcal/day, only 23% knew that approximately the same amount was needed for a febrile post-operative patient. Sixteen percent knew antibiotic treatment to be the most common reason for enteral feeding-related diarrhoea. CONCLUSIONS Knowledge about the assessment and management of undernutrition among doctors, medical students, nurses and pharmacists was poor. This questionnaire provides a framework for teaching and auditing the effectiveness of an educational program.

Abstract
This study aimed to evaluate whether food fortification and snacks could increase the energy and protein intakes of hospital patients. The control group of 82 consecutive admissions on medical, elderly care and orthopaedic wards ate freely from the hospital menu. Subsequently, an intervention group of 62 patients were offered fortified food and snacks, providing an extra 22.2|g protein/day and 966 kcal/day in addition to the standard menu. Fortification significantly increased energy intake in the intervention group (P = 0.007, independent samples t-test), having the greatest effect on groups with the lowest energy intake, that is male and female orthopaedic, female medical and female elderly patients (84 cent of total). The increases in energy intake were 21.3 cent, 21.4 cent, 23 cent and 19.6 cent respectively. Although the increased energy and protein intake represented 25.6 cent and 22.5 cent respectively, of the supplements given, and suggested that wastage was high, it was nevertheless sufficient to remove energy deficit. We therefore propose that provision of fortified food and snacks is a convenient method of improving the nutritional intakes of hospital patients.

Abstract
OBJECTIVE To document the prevalence of undernutrition/overnutrition in patients on peritoneal dialysis (PD) and to examine whether nutritional status (NS) changes with time on this form of dialysis. DESIGN Retrospective observational study. Patients had been on PD >2 years. Data included age, gender, diagnosis, peritonitis rate, anthropometry and biochemistry. A classification system for NS was devised using BMI, TSF, MAMC and serum albumin. SETTING Regional Peritoneal Dialysis Programme, University Teaching Hospital. PATIENTS 82 patients were on PD on March 1994. A cohort of 28 patients remained on PD after 2 years and complete nutritional data was available for 23 of these patients (9 male, 14 female: mean age 58yrs). RESULTS 65% of patients were classified as having an acceptable NS at the start of PD and 56% were classified as acceptable at the latest assessment. The prevalence of mild/moderate undernutrition both at the start of PD and at the latest assessment was 26% (different patients at each assessment). No patients were classified as severely undernourished. The prevalence of overnutrition at the start of PD was 9% and at the latest assessment was 17%. There was no statistically significant difference in NS between diabetics and non-diabetics nor between male and female patients although undernutrition was more frequently observed in males. Overnutrition increased with time in both genders but this did not reach statistical significance. There was no difference in initial NS between those who remained on PD and those who died. Change in NS was not related to peritonitis rate. CONCLUSION Whereas this study has insufficient statistical power to avoid a Type II error it supports our clinical observation that NS does not substantially change with time in this population. There are, however, a small number of individuals who exhibit changes in NS. Given the difficulty in predicting change in NS with time, regular nutritional assessment is important to identify those who require more intensive dietetic intervention.

Abstract
This prospective randomised trial compared the performance of three dressing protocols in the management of 36 dehisced surgical abdominal wounds: a standard alginate; a gauze moistened with sodium hypochlorite (0.05%); and a combine dressing pad. Outcomes assessed were: healing time (cm2 per day and cm3 per day), patient comfort (pain and satisfaction) and cost. There were no statistically significant differences in healing rates between the three groups but there was a trend for the combine dressing pad protocol to produce a greater reduction in wound area. The combine dressing pad protocol performed well when compared with the calcium alginate in terms of healing time, patient comfort and cost. Maximum pain was significantly greater (p = 0.011) and satisfaction significantly lower among patients who received the sodium hypochlorite protocol. Costs during the in-patient phase were also substantially higher for the sodium hypochlorite protocol. Trial results support the view that sodium hypochlorite dressing protocols for surgical wounds should be abandoned.
