Effect of supplements/intensive nutrition on pressure ulcer healing: a multicentre, randomised controlled study.

OBJECTIVE: To investigate the effectiveness of an intensive nutrition intervention or use of wound healing supplements compared with standard nutritional care in pressure ulcer (PU) healing in hospitalised patients. METHOD: Adult patients with a Stage II or greater PU and predicted length of stay (LOS) of at least seven days were eligible for inclusion in this pragmatic, multicentre, randomised controlled trial (RCT). Patients with a PU were randomised to receive either: standard nutritional care (n=46); intensive nutritional care delivered by a dietitian (n=42); or standard care plus provision of a wound healing nutritional formula (n=43). Relevant nutritional and PU parameters were collected at baseline and then weekly or until discharge. RESULTS: Of the 546 patients screened, 131 were included in the study. Participant mean age was 66.1±16.9 years, 75 (57.2%) were male and 50 (38.5%) were malnourished at recruitment. Median length of stay was 14 (IQR: 7-25) days and 62 (46.7%) had ≥2 PUs at the time of recruitment. Median change from baseline to day 14 in PU area was -0.75cm2 (IQR: -2.9_-0.03) and mean overall change in Pressure Ulcer Scale for Healing (PUSH) score was -2.9 (SD 3.2). Being in the nutrition intervention group was not a predictor of change in PUSH score, when adjusted for PU stage or location on recruitment (p=0.28); it was not a predictor of PU area at day 14, when adjusted for PU stage or area on recruitment (p=0.89) or PU stage and PUSH score on recruitment (p=0.91), nor a predictor of time to heal. CONCLUSION: This study failed to confirm a significant positive impact on PU healing of use of an intensive nutrition intervention or wound healing supplements in hospitalised patients. Further research that focuses on practical mechanisms to meet protein and energy requirements is needed to guide practice.

Effectiveness of dietary counseling with or without nutrition supplementation in hospitalized patients who are malnourished or at risk of malnutrition: A systematic review and meta-analysis.

BACKGROUND: Nutrition support is associated with improved survival and nonelective hospital readmission rates among malnourished medical inpatients; however, limited evidence supporting dietary counseling is available. We intend to determine the effect of dietary counseling with or without oral nutrition supplementation (ONS), compared with standard care, on hospitalized adults who are malnourished or at risk of malnutrition. METHODS: We searched MEDLINE/PubMed, CINAHL, Embase, Scopus, The Cochrane Library, and Google Scholar for studies listed from January 1, 2011, to August 31, 2021. Meta-analysis was performed to obtain pooled risk ratios (RRs) and 95% CIs to estimate the effect. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the certainty of the evidence. RESULTS: Sixteen studies were identified. Compared with standard care, dietary counseling with or without ONS probably does not reduce inpatient rates of 30-day mortality (RR = 1.24; 0.60-2.55; I2 = 45%; P = 0.56; moderate certainty), slightly reduces 6-month mortality (RR = 0.83; 0.69-1.00; I2 = 16%; P = 0.06; high certainty), reduces complications (RR = 0.85; 0.73-0.98; I2 = 0%; P = 0.03; high certainty), and may slightly reduce readmission (RR = 0.83; 0.66-1.03; I2 = 55%; P = 0.10; low certainty) but may not reduce length of stay (mean difference: -0.75 days; -1.66-0.17; I2 = 70%; P = 0.11; low certainty). Intervention may result in slight improvements in nutrition status/intake and weight/body mass index (low certainty). CONCLUSIONS: There is an increase in the certainty of evidence regarding the positive impact of dietary counseling on outcomes. Future studies should standardize and provide details/frequencies of counseling methods and ONS adherence to determine dietary counseling effectiveness.

Economic Evaluation of Nutrition Support in the Prevention and Treatment of Pressure Ulcers in Acute and Chronic Care Settings: A Systematic Review.

BACKGROUND: Recent developments in nutrition intervention indicated clinical effectiveness for pressure ulcer (PU) prevention and treatment, but it is important to assess whether they are cost-effective. The aims of this systematic review are to determine the cost-effectiveness and clinical outcomes of nutrition support in PU prevention and treatment. METHODS: A systematic search of randomized controlled trials, observational studies, and statistical models that investigated cost-effectiveness and economic outcomes for prevention and/or treatment of PUs were performed using standard literature and electronic databases. RESULTS: Fourteen studies met the inclusion criteria, which included 3 randomized controlled trials with their companion economic evaluations, 4 model-based, 2 cohort, 1 pre and post, and 1 prospective controlled trial. Risk of bias assessment for all of the uncontrolled or observational trials revealed high or serious risk of bias. Interventions that incorporated specialized nursing care appeared to be more effective in prevention and treatment of PUs, compared with single intervention studies. There is a trend of improved PU healing when additional energy/protein are provided. PU prevention ($250-$9,800) was less expensive than treatment ($2,500-$16,000). Nutrition intervention for PU prevention was cost-effective in 87.0%-99.99% of the simulation models. CONCLUSIONS: There is potential cost-saving and/or cost-effectiveness of nutrition support in the long term, as predicted by the model-based PU prevention studies in the review. Prevention of PU also appears to be more cost-effective than treatment. A multidisciplinary approach to managing PU is more likely to be cost-effective.

Improving nutrition care and intake for older hospital patients through system-level dietary and mealtime interventions.

BACKGROUND & AIMS: Interventions such as oral nutritional supplements (ONS), fortified meals and mid-meals, feeding assistants and Protected Mealtimes have shown some impact on nutritional intake in research studies, but embedding them in practise remains challenging. This study monitored nutritional intake of older medical inpatients as dietary and mealtime interventions were progressively implemented into routine practise. METHODS: Series of three prospectively evaluated patient cohorts allowed comparison of nutritional intake of 320 consented medical inpatients aged 65 + years: cohort 1 (2007-8), cohort 2 (2009) and cohort 3 (2013-14) as nutrition care interventions were progressively introduced and embedded. Interventions focused on 'assisted mealtimes', fortified meals and mid-meals, and ONS. Energy and protein intake were calculated from visual plate waste of individual meal and mid-meal components on day 5 of admission. Nutrition care processes were evaluated by mealtime audits of diet type, assistance and interruptions on the same day. One-way ANOVA and chi square tests were used for comparison between cohorts. RESULTS: Significant, progressive improvements in energy and protein intake were seen between cohorts (energy: cohort 1: 5073 kJ/d; cohort 2: 5403 kJ/d; cohort 3: 5989 kJ/d, p = 0.04; protein: cohort 1: 48 g/d, cohort 2: 50 g/d, cohort 3: 57 g/d, p = 0.02). Greater use of fortified meals and mid-meals and sustained improvements in mealtime assistance likely contributed to these improvements. CONCLUSIONS: Multi-faceted system-level approach to nutrition care, including changes to dietary and mealtime care processes, was associated with measureable and sustained improvements in nutritional intake of older inpatients over a seven year period.

Investigation of p16 status, chemotherapy regimen, and other nutrition markers for predicting gastrostomy in patients with head and neck cancer.

BACKGROUND: The purpose of this study was to determine if p16 status, chemotherapy regimen, or other nutrition markers could improve protocol accuracy in predicting proactive gastrostomy in patients with head and neck cancer. METHODS: Patients who received curative treatment from July 2010 to June 2011 were included (n = 269). Associations among dependent variables (age, sex, tumor site, staging, treatment, p16 status, albumin, and Malnutrition Screening Tool [MST] score), the protocol risk rating, and requirement for proactive gastrostomy were examined. RESULTS: Current protocol correctly identified 81 of 88 high-risk patients (92%) for gastrostomy, but incorrectly classified 32 of 181 low-risk patients (18%). Analysis of low-risk patients with oral or oropharyngeal cancers, found p16-positive disease had 4.4 times greater odds (p = .049), and those at risk of malnutrition had 4.5 times greater odds (p = .019) of requiring gastrostomy. CONCLUSION: Malnutrition risk and p16 status could be used to identify further patients who may benefit from proactive gastrostomy. © 2017 Wiley Periodicals, Inc. Head Neck 39: 868-875, 2017.

Nutritional therapy in patients with acute pancreatitis requiring critical care unit management: a prospective observational study in Australia and New Zealand.

OBJECTIVE: To determine nutritional therapy practices of patients with severe acute pancreatitis (defined as those receiving critical care management in an intensive care unit or high-dependency unit) in Australia and New Zealand with focus on the choice of enteral nutrition or parenteral nutrition. DESIGN: Prospective observational multicentered study performed at 40 sites in Australia and New Zealand over 6 months. SETTING: Intensive care units or high-dependency units within Australia and New Zealand. PATIENTS: Those with severe acute pancreatitis diagnosed by elevated lipase and/or amylase. Patients with chronic pancreatitis were excluded. MEASUREMENTS: The primary outcome was the proportion of patients who received enteral nutrition, parenteral nutrition, or concurrent enteral nutrition/parenteral nutrition. Secondary outcomes included other aspects of nutritional therapy and the severity and clinical outcomes of acute pancreatitis. MEASUREMENTS AND MAIN RESULTS: We enrolled 121 patients and 117 were analyzed. The mean age was 61 (sd 17) years and 53% were men. Enteral nutrition was delivered to 58 (50%; 95% confidence interval [CI], 41-59%) and parenteral nutrition to 49 (42%; 95% CI, 33-51%) patients. Parenteral nutrition was more frequently used as the initial therapy (58%; 95% CI, 49-67%) than enteral nutrition (42%; 95% CI, 33-51%). The most common reason for parenteral nutrition prescription was the treating doctor's preference (60%). Enteral nutrition (74%) was more often used than parenteral nutrition (40%) on any individual study day. Concurrent enteral nutrition and parenteral nutrition occurred in 28 (24%) patients on 14% of days. Complications of acute pancreatitis requiring critical care unit management were observed in 45 (39%) patients. The median (interquartile range) duration of intensive care unit and hospital stay were 5 (2-10) and 19 (9-31) days, respectively. The hospital mortality rate was 15% (95% CI, 8-21%), and there was a tendency toward higher mortality for patients who only received parenteral nutrition than for those who only received enteral nutrition (28% vs. 7%, p=.06). CONCLUSIONS: For patients with acute pancreatitis requiring critical care unit management in Australian and New Zealand intensive care units, enteral nutrition is used most commonly, but parenteral nutrition is more often used as the initial route of nutritional therapy. Given that clinical practice guidelines currently recommend enteral nutrition as the initial route of nutritional therapy in severe acute pancreatitis, improved education about and dissemination of these guidelines seems warranted.

Length of stay patterns for patients of an acute care hospital: implications for nutrition and food services.

OBJECTIVE: Shortened hospital average length of stay (ALOS) has been used to justify rationalisation of some services, but, by definition, some patients stay for longer than the average. The objective of this study was to explore lengths of stay and proportions of hospital occupied bed-days (OBDs) of those admitted for longer time periods to inform service planning. METHODS: The proportion and ALOS of overnight separations at an Australian tertiary hospital were assessed for admissions of up to 4 days and 4 days or more. This was repeated for 7, 14 and 28 days. The proportion of OBD's for each time period was determined. RESULTS: While the proportion of total hospital patients staying for 4, 7, 14 and 28 days or more is relatively small (21.9%, 13.5%, 6.2%, 2.6%, respectively), they represent a large proportion of OBD's (74.9%, 67.2%, 50.8%, 34.2%) with an ALOS of 14.0, 20.3, 33.7, and 54.4 days, respectively. The majority of long-stay patients were in acute care. CONCLUSION: Substantial proportions of OBD's are due to patients admitted for time periods far greater than reflected by ALOS. Hospitals need to rethink how to optimally accommodate the nutrition and food requirements of the large patient numbers admitted for longer time periods, many of whom are at increased risk of malnutrition.
