Hospital malnutrition: the Brazilian national survey (IBRANUTRI): a study of 4000 patients.

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.

Risk factors for malnutrition in patients undergoing gastroenterological and hernia surgery: an analysis of 374 patients.

OBJECTIVE: The aim of this study was to assess the nutritional status of 374 surgical patients with gastrointestinal disease and hernias of the abdominal wall; to identify risk factors associated with a poorer nutritional status in this group of patients and to assess awareness of the patient's nutritional status by medical teams. SUMMARY BACKGROUND DATA: Malnutrition is prevalent among surgical patients and is associated with higher surgical complication rates and mortality. The major causes of poor nutritional status are related to the underlying disease, socio-economic factors, age, and length of hospitalization. Despite its high prevalence, medical teams often overlook malnutrition, and screening of these patients is not routine. It is of utmost importance to identify patients at risk for malnutrition in order to prevent related complications. METHODS: The 374 patients evaluated in this study were a subgroup of a larger multicenter, cross-sectional, randomized study that was carried out in 1996. Nutritional status was assessed by using Subjective Global Assessment. RESULTS: Malnutrition was present in 55% of the patients, with 19% of the patients severely malnourished. The presence of cancer, infection, age over 60 years, upper gastrointestinal disease, and longer length of hospital stay all negatively influenced nutritional status. Despite the high prevalence of malnutrition, the medical teams only assessed the nutritional status of a few patients. CONCLUSION: Malnutrition was highly prevalent in this setting of patients. Therefore, patients with the risk factors above presented should routinely undergo nutritional screening and/or assessment in order to be able to early diagnose or prevent malnutrition and its correlated morbidity and mortality.

Peripheral parenteral nutrition: an option for patients with an indication for short-term parenteral nutrition.

OBJECTIVE: The aim of this study was to examine and describe our experience with the use of peripheral parenteral nutrition (PPN). METHODS: Patients with an indication for parenteral nutrition for less than 15 days received it via a peripheral vein via a short, 20 or 22 gauge French polyurethane catheter. Parenteral nutrition had a final osmolality of 993 mOsm/l and was administered by infusion pump. The nutritional status of patients was assessed by the Subjective Global Assessment (SGA) technique. Patients were followed by a trained nutritional team and the access site was changed if problems developed. RESULTS: Fifty-three patients were followed with a mean age of 59.5 +/- 17.5 years. There were 36 males (69.2%). Nutritional requirements were reached in 67.6% of the patients within 2.9 +/- 0.7 days. The mean time on parenteral nutrition was 7.2 +/- 6.6 days. In 74.3% of the cases parenteral nutrition was offered until the end of the planned treatment. Pain at the venipuncture site occurred in 17.1% of the cases, pain and fever in 20% and pain, hyperthermia and edema in 2.8%. No patient developed an abscess. CONCLUSIONS: PPN can benefit a great number of patients without the risks linked to a venous central catheter. Complications associated with PPN are low especially when the care and follow-up are provided by a nutritional support team.

Total nutritional therapy: a nutrition education program for physicians.

OBJECTIVE: Almost half of all hospitalized patients are malnourished with low physician awareness or implementation of nutrition support. To address this problem, a 2-day immersion course in clinical nutrition for physicians was developed by the Latin American Federation of Parenteral and Enteral Nutrition (FELANPE) with support from Abbott Laboratories. The goal of Total Nutritional Therapy (TNT) is to help physicians utilize this nutrition knowledge to increase their awareness of malnutrition and implementation of nutritional therapy. Since 1997, over 8,000 physicians have completed the TNT course in 16 Latin American countries. RESEARCH METHODS & PROCEDURES: During 1999 and 2000, 675 participants responded to a survey 6 months after having completed the TNT course to determine what impact the course had on the use of nutrition assessment, nutrition support teams, or nutrition consultations in their clinical practice, and if they had participated in any nutrition association or conferences. RESULTS: The majority of physicians who completed the survey increased their use of nutrition assessment and time dedicated to nutrition therapy, and increased the number of their patients placed on nutrition therapy. CONCLUSIONS: The TNT course has been shown to be an efficient model of clinical nutrition education for general physicians. The course should be considered as part of the training of medical residents.
