RESUMO
More information is needed about the impact of outpatient nutrition care from a registered dietitian nutritionist (RDN) on patient outcomes. This study aimed to assess the feasibility of a cohort study design to evaluate impact of RDN nutrition care on patient outcomes, describe clinic malnutrition screening practices, and estimate statistical parameters for a larger study. Seventy-seven patients with lung, esophageal, colon, rectal, or pancreatic cancer from six facilities were included (41 received RDN care and 36 did not). RDN nutrition care was prospectively documented for six months and documented emergency room visits, unplanned hospitalizations and treatment changes were retrospectively abstracted from medical records. Most facilities used the Malnutrition Screening Tool (MST) to determine malnutrition risk. Patients receiving RDN care had, on average, five, half hour visits and had more severe disease and higher initial malnutrition risk, although this varied across sites. Documented medical and treatment outcomes were relatively rare and similar between groups. Estimated sample size requirements varied from 113 to 5856, depending on tumor type and outcome, and intracluster correlation coefficients (ICCs) ranged from 0 to 0.47. Overall, the methods used in this study are feasible but an interventional or implementation design might be advantageous for a larger study.

OBJECTIVE: A randomized, multicenter, controlled double-blind trial was performed in women with cyclic breast pain (mastalgia) associated with fibrocystic breast changes (FBCs) to determine whether a nutritional formula reduced breast pain and/or nodularity. STUDY DESIGN: Women were randomized to receive a specifically designed liquid formulation (n = 93) (1 g gamma-linolenic acid [GLA], 750 µg iodine, and 70 µg selenium) or control formula (n = 95) (without GLA, iodine, and selenium) daily for three cycles. Women recorded breast pain, medications, and menstrual signs daily using interactive voice-response system. Nodularity was determined by physical breast examination. RESULTS: Breast pain scores decreased similarly in the experimental (-32.2%) and control (-33.1%) groups (p = 0.64). Nodularity was reduced in the experimental, but not the control group (p = 0.03). Among women who continued pain medication, the amount was reduced in the experimental group relative to controls (p = 0.02). CONCLUSION: Women with FBC using the formula containing GLA, iodine, and selenium experienced reduced nodularity and in those women who took over-the-counter breast pain medication, a decrease in the quantity of pain medication was observed.

OBJECTIVES: This study evaluated the glycemic, insulinemic, and glucagon-like peptide-1 (GLP-1) responses of subjects with type 2 diabetes mellitus to consumption of two diabetes-specific tube-feeding formulas (slowly digested carbohydrate formula [SDC] and diabetes-specific formula [DSF]) and one formula intended for individuals without diabetes (standard formula [STND]). METHODS: Forty-eight subjects controlled with diet and/or oral antihyperglycemic medications received the SDC, DSF, and STND. Postprandial glucose, insulin, and GLP-1 were measured on three occasions after an overnight fast in a double-blinded, randomized, three-treatment, crossover design. RESULTS: The positive area under the curve for glucose and insulin with the STND was higher (P < 0.001) compared with the SDC and DSF. The adjusted GLP-1 concentration at 60 min was higher for the SDC compared with the DSF and STND (P < 0.05). CONCLUSION: Both lower-carbohydrate diabetes-specific formulas resulted in a lower postprandial blood glucose response compared with the STND. The formula also rich in slowly digested carbohydrate and monounsaturated and omega-3 fatty acids (SDC) produced significantly lower blood glucose and insulin responses and higher levels of GLP-1 in the presence of significantly lower insulin concentrations. These results support the view that the quantity and quality of carbohydrate and fat may play important roles in the management of patients with type 2 diabetes mellitus and could result in improved beta-cell function over the long term.

OBJECTIVES: To identify resident, wound, and treatment characteristics associated with pressure ulcer (PrU) healing in long-term care residents. DESIGN: Retrospective cohort study with convenience sampling. SETTING: Ninety-five long-term care facilities participating in the National Pressure Ulcer Long-Term Care Study throughout the United States. PARTICIPANTS: Eight hundred eighty-two residents, aged 18 and older, with length of stay of 14 days or longer, who had at least one Stage II to IV PrU. MEASUREMENTS: Data collected for each resident over a 12-week period included resident characteristics, treatment characteristics, and change in PrU area. Data were obtained from medical records, Minimum Data Set, and other records. RESULTS: Two multiple regression models, one for each stage grouping (Stage II, Stage III and IV), were completed. The area of Stage II PrU was reduced more with moist (F=21.91, P<.001) than with dry (F=13.41, P<.001) dressings. PrUs cleaned with saline or soap showed less decrease in area (F=12.34, P<.001) than PrUs cleaned with other cleansers such as antiseptic, antibiotic, or commercial cleansers. Change in area of Stage III and IV PrUs was related to sufficient enteral feeding (F=5.23, P=.02), enteral feeding without higher acuity levels (F=3.94, P=.048), size of PrU (very large (F=120.89, P=.001) and large (F=27.82, P=.001)), and type of dressing (moist (F=14.70, P<.001) and dry (F=5.88, P=.02)). Stage III and IV PrUs increased in area when debrided (F=5.97, P=.02). The overall models were significant (Stage III and IV, F=20.30, coefficient of determination (R2)=0.06, P<.001; Stage II, F=40.28, R2=0.13, P<.001) but explained little of the variation in change in PrU area. CONCLUSION: In this sample of nursing facility residents, use of moist dressings (Stage II, Stage III and IV) and adequate nutritional support (Stage III and IV) are strong predictors of PrU healing.

More than 20% of residents who have been in long-term care (LTC) facilities for 2 or more years will develop at least one pressure ulcer (PU). Residents suffer pain, disfigurement, and decreased quality of life, and their risk of illness and death increases. LTC facilities face censure from residents, their families, and surveyors and the threat of expensive lawsuits. Lawsuits are typically based on contentions of residents with a PU--or their advocates--that the LTC facility was negligent and failed to provide the care that, by industry standards, it must provide to prevent or manage such wounds (managing pressure, incontinence, and nutrition). In this article, data from 1999 and 2002 are presented, showing that lawsuits related to PUs are increasingly common and costly for LTC owners and care providers. Residents realized some type of recovery against the facility in 87% of the cases (verdicts for the resident plus settlements) and were awarded amounts as high as $312 million in damages. Even LTC administrators who believe that care in their facility equals or exceeds industry standards often settle lawsuits out of court to avoid jury verdicts. The data also show that jury awards were highest for PUs caused by multiple factors and that the highest awards for PUs caused by a single factor were seen when that factor was inadequate nutrition. LTC providers can help improve the health and quality of life of their residents, improve survey results, and minimize their risk of expensive lawsuits by developing, implementing, and documenting a plan of basic measures to prevent PUs.

OBJECTIVES: To identify resident, treatment, and facility characteristics associated with pressure ulcer (PU) development in long-term care residents. DESIGN: Retrospective cohort study with convenience sampling. SETTING: Ninety-five long-term care facilities participating in the National Pressure Ulcer Long-Term Care Study throughout the United States. PARTICIPANTS: A total of 1,524 residents aged 18 and older, with length of stay of 14 days or longer, who did not have an existing PU but were at risk of developing a PU, as defined by a Braden Scale for Predicting Pressure Sore Risk score of 17 or less, on study entry. MEASUREMENTS: Data collected for each resident over a 12-week period included resident characteristics (e.g., demographics, medical history, severity of illness using the Comprehensive Severity Index, Braden Scale scores, nutritional factors), treatment characteristics (nutritional interventions, pressure management strategies, incontinence treatments, medications), staffing ratios and other facility characteristics, and outcome (PU development during study period). Data were obtained from medical records, Minimum Data Set, and other written records (e.g., physician orders, medication logs). RESULTS: Seventy-one percent of subjects (n=1,081) did not develop a PU during the 12-week study period; the remaining 29% of residents (n=443) developed a new PU. Resident, treatment, and facility characteristics associated with greater likelihood of developing a Stage I to IV PU included higher initial severity of illness, history of recent PU, significant weight loss, oral eating problems, use of catheters, and use of positioning devices. Characteristics associated with decreased likelihood of developing a Stage I to IV PU included new resident, nutritional intervention (e.g., use of oral medical nutritional supplements and tube feeding for >21 days), antidepressant use, use of disposable briefs for more than 14 days, registered nurse hours of 0.25 hours per resident per day or more, nurses' aide hours of 2 hours per resident per day or more, and licensed practical nurse turnover rate of less than 25%. When Stage I PUs were excluded from the analyses, the same variables were significant, with the addition of fluid orders associated with decreased likelihood of developing a PU. CONCLUSION: A broad range of factors, including nutritional interventions, fluid orders, medications, and staffing patterns, are associated with prevention of PUs in long-term care residents. Research-based PU prevention protocols need to be developed that include these factors and target interventions for reducing risk factors.
