Prevalence, risk factors, and clinical outcomes of vitamin C deficiency in adult hospitalized patients in high-income countries: a scoping review.

BACKGROUND: Assessment for vitamin C deficiency (VCD) is rarely undertaken in an acute hospital setting in high-income countries. However, with growing interest in VCD in community settings, there is emerging evidence investigating the prevalence and impact of VCD during hospitalization. OBJECTIVES: In this scoping review, the prevalence of VCD in adult hospitalized patients is explored, patient characteristics are described, and risk factors and clinical outcomes associated with VCD are identified. METHODS: A systematic scoping review was conducted in accordance with the PRISMA-ScR framework. The Ovid MEDLINE, Ovid Embase, Scopus, CINAHL Plus, Allied and Complementary Medicine Database, and the Cochrane Library databases were searched for interventional, comparative, and case-series studies that met eligibility criteria, including adult hospital inpatients in high-income countries, as defined by the Organization for Economic Co-operation and Development, that reported VCD prevalence using World Health Organization reference standards. These standards define VCD deficiency as plasma or serum vitamin C level <11.4 µmol/L, wholeblood level <17 µmol/L, or leukocytes <57 nmol/108 cells. RESULTS: Twenty-three articles were included, representing 22 studies. The cumulative prevalence of VCD was 27.7% (n = 2494; 95% confidence interval [CI], 21.3-34.0). High prevalence of VCD was observed in patients with severe acute illness and poor nutritional status. Scurvy was present in 48% to 62% of patients with VCD assessed in 2 studies (n = 71). Being retired (P = 0.015) and using excessive amounts of alcohol and tobacco (P = 0.0003) were independent risk factors for VCD (n = 184). Age was not conclusively associated with VCD (n = 631). Two studies examined nutrition associations (n = 309); results were inconsistent. Clinical outcomes for VCD included increased risk of frailty (adjusted odds ratio, 4.3; 95%CI, 1.33-13.86; P = 0.015) and cognitive impairment (adjusted odds ratio, 2.93; 95%CI, 1.05-8.19, P = 0.031) (n = 160). CONCLUSIONS: VCD is a nutritional challenge facing the healthcare systems of high-income countries. Research focused on early identification and treatment of patients with VCD is warranted.

Nutrition outcomes and treatment toxicities in patients with head and neck cancer receiving helical intensity-modulated radiotherapy.

BACKGROUND: Helical intensity-modulated radiotherapy (H-IMRT) provides excellent limitation of dose to tissues not requiring treatment, although acute toxicity still occurs. The present study aimed to determine how treatment-related acute toxicities affect nutrition outcomes in patients with head and neck cancer. METHODS: A prospective observational study was conducted in 194 patients undergoing curative intent H-IMRT with or without other treatment modalities. Weight outcomes (kg) and acute toxicity and dysphagia data were collected during treatment using Common Toxicity Criteria for Adverse Effects (CTCAE), version 4.0. RESULTS: Significant weight loss (> 10%) was observed in 30% of high nutritional risk patients and 7% of low nutritional risk patients. Nausea, adjusted for baseline dysphagia, in high nutritional risk patients and nausea, dysphagia and pharyngeal mucositis in low nutritional risk patients were significant factors in explaining the percentage loss in baseline weight to treatment completion. CONCLUSIONS: Significant weight loss remains an issue during treatment, despite improvements in radiotherapy technology and high-level multidisciplinary care.

A qualitative comparison of the nutrition care experiences of carers supporting patients with head and neck cancer throughout surgery and radiation treatment and survivorship.

PURPOSE: To understand and compare the nutrition care experiences of carers supporting patients throughout surgery and radiation treatment for head and neck cancer (HNC) to inform changes to service delivery in the inpatient and outpatient setting to ensure carers needs in their supportive role throughout the treatment and survivorship period are met. METHODS: As part of a larger study, narrative interviews were completed with fourteen carers of patients diagnosed with HNC at 2 weeks, 3 months and 12 months post-treatment completion. Reflexive thematic analysis was used to interpret and understand differences in carer experiences of nutrition care between surgery and radiation treatment. RESULTS: Two main themes across each treatment modality were identified: (1) access to information and support from healthcare professionals and (2) adjustment to the physical and psychological impact of treatment. CONCLUSION: This study highlights the increasing need to ensure carers are included in the provision of nutrition information and support to patients throughout and beyond their treatment trajectory. Having structured support available to patients and carers throughout radiation treatment meant that carer needs were reduced. However, without the opportunity for structured support in the inpatient setting, many carers expressed high care needs in supporting patients in the post-surgical phase. IMPLICATIONS FOR CANCER SURVIVORS: Providing carers with access to structured support for nutrition care in the inpatient and outpatient setting can reduce their supportive care needs throughout the treatment and survivorship period.

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.

Exploring dyadic management of nutrition care throughout and beyond head and neck cancer treatment.

AIMS AND OBJECTIVES: To identify how patients and carers collaborate to manage nutrition care throughout and beyond head and neck cancer (HNC) treatment as a step towards identifying changes to service delivery that are inclusive of the needs of the patient-carer dyad. BACKGROUND: Research in the field of dyadic interventions in cancer care is emerging, and there has been little work exploring patient-carer dyad needs in the provision of nutrition care in HNC. DESIGN: A qualitative study design was used. METHODS: Narrative interviews were completed with 13 patients and 15 carers over a 12-month period (prior to treatment commencing, and 2 weeks, 3 months and 12 months post-treatment completion). Deductive analysis of interview transcripts was performed using directed content analysis guided by the Theory of Dyadic Illness Management (TDIM). COREQ guidelines were used. RESULTS: Seven themes across four TDIM constructs were identified: (1) understanding and adapting to physical challenges impacting nutrition intake, (2) adjusting to emotional impact of changes to eating and drinking, (3) providing practical support, (4) intrapersonal characteristics, (5) interpersonal characteristics, (6) healthcare culture and (7) managing carer burnout. CONCLUSION: This study highlights the importance of healthcare professionals recognising the patient and carer dyad as a team to enhance engagement in nutrition care and to ensure that their physical and psychological support needs across the cancer continuum are met. RELEVANCE TO CLINICAL PRACTICE: It is important that healthcare professionals understand information and support needs and preferences within patient-carer dyads prior to HNC treatment commencing and adapt care and interventions based on their changing needs throughout and beyond the treatment period.

Patient and carer experience of nutrition care throughout and beyond treatment for head and neck cancer: a qualitative longitudinal study.

Nutrition care plays a critical role in optimising outcomes for patients receiving treatment for head and neck cancer (HNC), with carers playing an important role in supporting patients to maintain nutrition intake. This study explores patient and carer experience of nutrition care from diagnosis of HNC to 1 year post treatment completion to identify areas for improvement of service delivery. A longitudinal qualitative study design was used with a heterogeneous sample of 20 patients and 15 carers of patients undergoing curative intent treatment for HNC. Interviews conducted at four time points provided a total of 117 interview datasets that were analysed using reflexive thematic analysis based on Gadamerian hermeneutic inquiry. Patient and carer experiences were reflected in two primary themes: (1) the battle to maintain control and (2) navigating the road ahead. This research identifies the need to co-design strategies to improve nutrition care that is inclusive of patients and carers.

Identifying Low Value Malnutrition Care Activities for De-Implementation and Systematised, Interdisciplinary Alternatives-A Multi-Site, Nominal Group Technique Approach.

Malnutrition risk is identified in over one-third of inpatients; reliance on dietetics-delivered nutrition care for all "at-risk" patients is unsustainable, inefficient, and ineffective. This study aimed to identify and prioritise low-value malnutrition care activities for de-implementation and articulate systematised interdisciplinary opportunities. Nine workshops, at eight purposively sampled hospitals, were undertaken using the nominal group technique. Participants were asked "What highly individualised malnutrition care activities do you think we could replace with systematised, interdisciplinary malnutrition care?" and "What systematised, interdisciplinary opportunities do you think we should do to provide more effective and efficient nutrition care in our ward/hospital?" Sixty-three participants were provided five votes per question. The most voted de-implementation activities were low-value nutrition reviews (32); education by dietitian (28); assessments by dietitian for patients with malnutrition screening tool score of two (22); assistants duplicating malnutrition screening (19); and comprehensive, individualised nutrition assessments where unlikely to add value (15). The top voted alternative opportunities were delegated/skill shared interventions (55), delegated/skill shared education (24), abbreviated malnutrition care processes where clinically appropriate (23), delegated/skill shared supportive food/fluids (14), and mealtime assistance (13). Findings highlight opportunities to de-implement perceived low-value malnutrition care activities and replace them with systems and skill shared alternatives across hospital settings.

Is fidelity to a complex behaviour change intervention associated with patient outcomes? Exploring the relationship between dietitian adherence and competence and the nutritional status of intervention patients in a successful stepped-wedge randomised clinical trial of eating as treatment (EAT).

BACKGROUND: Behavioural medicine is characterised by findings for the effectiveness and efficacy of complex behaviour change interventions. Comparatively, scant attention has been paid to key intervention components or mechanisms of action. Evaluating relationships between process variables (fidelity) and intervention effects is central to addressing this imbalance. Accordingly, in the current study, we sought to explore the magnitude and direction of effect between fidelity predictors (dietitian adherence and competence) and intervention effects (patient nutritional status) during the intervention phase of a real-world, stepped-wedge evaluation of 'EAT: Eating As Treatment'. METHODS: The EAT clinical trial was conducted within five major Australian hospitals located in Queensland, Western Australia, Victoria and South Australia between 2013 and 2016. EAT is a dietitian-delivered health behaviour change intervention designed to reduce malnutrition in head and neck cancer (HNC) patients undergoing radiotherapy. Dietitian adherence and competence ratings were derived from a 20% random sample of audio-recorded dietetic consultations (n=194) conducted after dietitians (n=18) were trained in EAT. Sessions were coded by trained, independent, coders using a study checklist, the Behaviour Change Counselling Index (BECCI) and items from the Cognitive Therapy Scale-Revised (CTS-R). Patient nutritional status was measured using the Patient-Generated Subjective Global Assessment (PGSGA). RESULTS: Dietitian adherence to a written nutrition plan (ß=7.62, 95% CI=0.65 to 14.58, p=0.032), dietitian adherence to behaviour change counselling (ß=0.69, 95% CI =0.02 to 1.38, p=0.045) and competence in delivering behaviour change counselling (ß=3.50, 95% CI =0.47 to 6.53, p=0.024) were significant predictors of patient nutritional status. Dietitian adherence and competence ratings were higher during consultations with intervention patients at greater risk of malnutrition. CONCLUSIONS: This study contributes new insights into the relationship between fidelity and treatment outcome by demonstrating that dietitian adherence and competence is greater when working with more challenging patients. This is likely central to the demonstrated success of the EAT intervention in reducing malnutrition and highlights the importance of ensuring that providers are adequately equipped to flexibly integrate intervention elements according to patient need. TRIAL REGISTRATION: This study is a process analysis of a stepped-wedge randomised controlled trial prospectively registered on the Australian New Zealand Clinical Trials Registry ( ACTRN12613000320752 ; Date of registration 21/03/2013).

"There's a lot of talent in the room but it's only really the medical talent that gets heard": a qualitative exploration of multidisciplinary clinicians' perspectives of optimal nutrition care of patients with head and neck cancer.

BACKGROUND: The high prevalence of malnutrition in patients with head and neck cancer (HNC) negatively impacts outcomes. The best-available evidence has been published in clinical nutrition guidelines; however, translation into practice has lagged. AIM: This project aimed to explore multidisciplinary team (MDT) clinicians' perspectives regarding barriers and enablers to best-practice nutrition care in order to inform the design of a new model of care. METHOD: Qualitative interviews were conducted with clinicians who were purposively sampled from a major HNC tertiary referral centre in Sydney, Australia. To elicit information regarding barriers and facilitators to change, a semi-structured interview schedule was developed, interviews were transcribed verbatim and analyzed employing an inductive thematic approach. The Consolidated Framework for Implementation Research (CFIR) was used to guide data analysis and interpretation of key themes identified. RESULTS: Nineteen participants (11 supportive care and eight medical clinicians) representing allied health, medical, and nursing disciplines participated. Five key themes were identified: (1) acknowledgement of dietetics expertise and access to resources to deliver nutrition care; (2) proactive versus reactive nutrition care; (3) integrated and coordinated care-"The One Stop Shop"; (4) MDT favours the medical model; and (5) leadership-within disciplines, within the MDT. CONCLUSIONS: MDT clinicians expressed similar views regarding delivering optimal nutrition care to this high nutritional risk patient group. However, perspectives differed at times between medical and supportive care clinicians, attributable to perceptions that current service structure favours the medical model. In order to design and deliver an evidence-based model of care, specific strategies will be required to ensure: early and ongoing access to expert nutrition care; nutrition care processes are proactive; integrated and coordinated care; and leadership, both intra- and inter-disciplinary. This novel exploration of MDT clinicians' views provides supporting evidence that multi-component implementation strategies comprising individual, team and system-level approaches will be essential to leverage sustainable change.

Dietitian assistant opportunities within the nutrition care process for patients with or at risk of malnutrition: a systematic review.

AIM: Shifting to models of care that incorporate delegation of nutrition care process actions to dietitian assistants could facilitate effective and efficient nutrition care delivery. This review aimed to determine if delegation of malnutrition care activities to dietitian assistants, when compared with routine nutrition care practices influences patient, healthcare and/or workforce outcomes for adult hospital inpatients with or at risk of malnutrition. METHODS: This review was undertaken in accordance with PRISMA guidelines, with five databases (CINAHL, Medline, PsycINFO, Embase and Scopus) searched systematically for studies published up to and including February 2020. Exclusion criteria included review articles and studies conducted in community settings. RESULTS: The search yielded 3431 results, with 11 studies eligible for inclusion. Across all domains of the nutrition care process, there is emerging evidence dietitian assistants may improve the delivery of nutrition care practices, patient, healthcare and workforce outcomes. Findings demonstrated various roles and scope of dietitian assistants' practice throughout the studies. Positive patient outcomes were found when dietitian assistants were part of a multi-disciplinary model of care. CONCLUSIONS: Implementing delegation of components of the nutrition care process to dietitian assistants is vital in the current health climate and should be considered in a future multidisciplinary model of nutrition care. Exploration of dietitian assistant roles and opportunities are required to expand and strengthen the evidence.

Translating Evidence-Based Guidelines into Practice-Are We Getting It Right? A Multi-Centre Prospective International Audit of Nutrition Care in Patients with Foregut Tumors (INFORM).

Malnutrition is highly prevalent in patients with foregut tumors comprising head and neck (HNC) and esophageal (EC) cancers, negatively impacting outcomes. International evidence-based guidelines (EBGs) for nutrition care exist; however, translation of research evidence into practice commonly presents considerable challenges and consequently lags. This study aimed to describe and evaluate current international nutrition care practices compared with the best-available evidence for patients with foregut tumors who are at high risk of malnutrition. A multi-centre prospective cohort study enrolled 170 patients commencing treatment of curative intent for HNC (n = 119) or EC (n = 51) in 11 cancer care settings in North America, Europe and Australia between 2016 and 2018. Adherence criteria were derived from relevant EBG recommendations with pooled results for participating centres reported according to the Nutrition Care Model at either system or patient levels. Adherence to EBG recommendations was: good (≥80%) for performing baseline nutrition screening and assessment, perioperative nutrition assessment and nutrition prescription for energy and protein targets; moderate (≥60 to 80%) for utilizing validated screening and assessment tools and pre-radiotherapy dietitian consultation; and poor (60%) for initiating post-operative nutrition support within 24 h and also dietetic consultation weekly during radiotherapy and fortnightly for 6 weeks post-radiotherapy. In conclusion, gaps in evidence-based cancer nutrition care remain; however, this may be improved by filling known evidence gaps through high-quality research with a concurrent evolution of EBGs to also encompass practical implementation guidance. These should aim to support multidisciplinary cancer clinicians to close evidence-practice gaps throughout the patient care trajectory with clearly defined roles and responsibilities that also address patient-reported concerns.

Patient and carer experience of nutrition care throughout treatment for head and neck cancer: a systematic qualitative review and thematic synthesis.

Nutrition care plays a critical role in the provision of best practice care to head and neck cancer (HNC) patients, with carers playing an important role in supporting patients to maintain nutrition intake. This qualitative systematic review investigated patient and carer experience of nutrition care throughout and beyond HNC treatment. Five databases were systematically searched for qualitative studies reporting on patient and carer experience of nutrition care throughout HNC. Twenty-five studies including 435 patients and 46 carers were identified, revealing three themes: information and support in the healthcare setting, enteral feeding challenges and management, and life outside hospital. Findings highlight the importance of providing individualised person-centred nutrition care to patients with HNC and their carers. Further qualitative research is needed to inform healthcare professionals about the needs of patients and carers to provide appropriate support throughout the treatment trajectory across and between different treatment modalities.

The Association Between Computed Tomography-Defined Sarcopenia and Outcomes in Adult Patients Undergoing Radiotherapy of Curative Intent for Head and Neck Cancer: A Systematic Review.

BACKGROUND: Computed tomography (CT)-defined sarcopenia is a demonstrated poor prognostic factor in patients with cancer; however, its influence on outcomes for patients with head and neck cancer (HNC) has not been established. OBJECTIVE: This review synthesizes current knowledge regarding the association between CT-defined sarcopenia and outcomes for adult patients undergoing radiotherapy with or without other treatment modalities of curative intent for HNC. METHODS: A systematic review of the literature published between January 2004 and June 2019 was conducted in Medline, Embase, Cumulative Index of Nursing and Allied Health Literature, Allied and Complementary Medicine Database, and PubMed. Empirical studies of CT-defined sarcopenia in adult patients (≥18 years) with HNC who had completed radiotherapy of curative intent with or without other treatment modalities were included. Outcomes reported included survival, prolonged radiotherapy breaks, and chemotherapy toxicity. Study quality was assessed using the American Academy of Nutrition and Dietetics Quality Criteria Checklist. Synthesis of outcomes and clinical relevance was performed using the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS: Of 11 studies (n = 3,461) identified, 3 were positive and 8 were neutral quality. Studies were heterogeneous in HNC diagnosis, ethnicity, definition of sarcopenia, CT level of evaluation, and skeletal muscle index threshold value. Eight definitions for sarcopenia were identified with pretreatment prevalence of 6.6% to 70.9% and posttreatment prevalence of 12.4% to 65.8%. Pretreatment sarcopenia was independently associated with reduced: overall survival (OS), 3-year OS, disease-free survival, prolonged radiotherapy breaks, and chemotherapy-related toxicities. Posttreatment sarcopenia was independently associated with reduced OS and 5-year OS. The overall certainty of evidence according to Grading of Recommendations Assessment, Development and Evaluation criteria was low for OS; 3-year, 5-year, and 10-year OS; locoregional control; locoregional failure; progression-free survival; metastasis-free survival, disease-specific survival; and disease-free survival and very low for distant metastasis, prolonged radiotherapy breaks, and chemotherapy toxicity-related outcomes. CONCLUSIONS: CT-defined sarcopenia is independently associated with reduced OS and treatment completion in patients with HNC and holds a clinically meaningful prognostic value. The certainty of the evidence requires strengthening with further research. Understanding the impact sarcopenia has on outcomes for these patients has implications for informing potential nutrition interventions and facilitating individualized care.

Best Evidence to Best Practice: Implementing an Innovative Model of Nutrition Care for Patients with Head and Neck Cancer Improves Outcomes.

Malnutrition is prevalent in patients with head and neck cancer (HNC), impacting outcomes. Despite publication of nutrition care evidence-based guidelines (EBGs), evidence-practice gaps exist. This study aimed to implement and evaluate the integration of a patient-centred, best-practice dietetic model of care into an HNC multidisciplinary team (MDT) to minimise the detrimental sequelae of malnutrition. A mixed-methods, pre-post study design was used to deliver key interventions underpinned by evidence-based implementation strategies to address identified barriers and facilitators to change at individual, team and system levels. A data audit of medical records established baseline adherence to EBGs and clinical parameters prior to implementation in a prospective cohort. Key interventions included a weekly Supportive Care-Led Pre-Treatment Clinic and a Nutrition Care Dashboard highlighting nutrition outcome data integrated into MDT meetings. Focus groups provided team-level evaluation of the new model of care. Economic analysis determined system-level impact. The baseline clinical audit (n = 98) revealed barriers including reactive nutrition care, lack of familiarity with EBGs or awareness of intensive nutrition care needs as well as infrastructure and dietetic resource limitations. Post-implementation data (n = 34) demonstrated improved process and clinical outcomes: pre-treatment dietitian assessment; use of a validated nutrition assessment tool before, during and after treatment. Patients receiving the new model of care were significantly more likely to complete prescribed radiotherapy and systemic therapy. Differences in mean percentage weight change were clinically relevant. At the system level, the new model of care avoided 3.92 unplanned admissions and related costs of $AUD121K per annum. Focus groups confirmed clear support at the multidisciplinary team level for continuing the new model of care. Implementing an evidence-based nutrition model of care in patients with HNC is feasible and can improve outcomes. Benefits of this model of care may be transferrable to other patient groups within cancer settings.

"Completely and utterly flummoxed and out of my depth": patient and caregiver experiences during and after treatment for head and neck cancer-a qualitative evaluation of barriers and facilitators to best-practice nutrition care.

BACKGROUND: Malnutrition is prevalent in patients with head and neck cancer (HNC), impacting on outcomes. Despite publication of best-practice nutrition care clinical guidelines, evidence-practice gaps persist. AIM: This project aimed to understand the perspectives of patients and their caregivers about nutritional care and how their unmet supportive care needs can be better addressed in designing a new model of care (MOC). The results will contribute to documenting the barriers and enablers to implementing best practice nutrition care for patients with HNC. METHOD: Qualitative interviews were conducted with patients who had completed radiotherapy with or without (+/-) other treatment modality (surgery and/or systematic therapy) of curative intent for HNC. Patients were purposively sampled from a major tertiary referral centre in Sydney, Australia. Patients' primary caregivers were also invited to participate if both parties consented. A semi-structured interview schedule was developed to elicit information about barriers and facilitators to change and inform development of the new MOC. Interviews were transcribed verbatim then analysed using an inductive thematic approach. This study was one component of a mixed methods design to explore the barriers and facilitators to best-practice nutrition care in a head and neck oncology unit. RESULTS: Eleven participants (seven patients, four caregivers) took part in the interviews. Four key themes were identified with branching themes within each: (1) being ill-prepared for the impact of treatment, even when advised; (2) navigating complex systems to meet significant care needs; (3) depleted by overwhelming and prolonged suffering; and (4) information lost in translation. CONCLUSIONS: This study highlights the unique and complex care needs of people with HNC and those caring for them. To design and successfully deliver a patient-centred MOC, specific strategies will be required to address: early and ongoing access to expert supportive care clinicians; integrated and coordinated care; individual information, education and support needs and; and education of MDT staff in accurate and consistent messaging, ensuring nutrition care is a collective responsibility. Nutrition care did not appear to be viewed separately to overall care from the patient perspective as the importance of nutrition ultimately became viewed as vital treatment.

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.

Eating As Treatment (EAT): A Stepped-Wedge, Randomized Controlled Trial of a Health Behavior Change Intervention Provided by Dietitians to Improve Nutrition in Patients With Head and Neck Cancer Undergoing Radiation Therapy (TROG 12.03).

PURPOSE: Malnutrition in head and neck cancer (HNC) treatment is common and associated with poorer morbidity and mortality outcomes. This trial aimed to improve nutritional status during radiation therapy (RT) using a novel method of training dietitians to deliver psychological techniques to improve nutritional behaviors in patients with HNC. METHODS AND MATERIALS: This trial used a stepped-wedge, randomized controlled design to assess the efficacy of the Eating As Treatment (EAT) program. Based on motivational interviewing and cognitive behavioral therapy, EAT was designed to be delivered by oncology dietitians and integrated into their clinical practice. During control steps, dietitians provided treatment as usual, before being trained in EAT and moving into the intervention phase. The training was principles based and sought to improve behavior-change skills rather than provide specific scripts. Patients recruited to the trial (151 controls, 156 intervention) were assessed at 4 time points (the first and the final weeks of RT, and 4 and 12 weeks afterward). The primary outcome was nutritional status at the end of RT as measured by the Patient-Generated Subjective Global Assessment. RESULTS: Patients who received the EAT intervention had significantly better scores on the primary outcome of nutritional status at the critical end-of-treatment time point (ß = -1.53 [-2.93 to -.13], P = .03). Intervention patients were also significantly more likely than control patients to be assessed as well-nourished at each time point, lose a smaller percentage of weight, have fewer treatment interruptions, present lower depression scores, and report a higher quality of life. Although results were not statistically significant, patients who received the intervention had fewer and shorter unplanned hospital admissions. CONCLUSIONS: This trial is the first of its kind to demonstrate the effectiveness of a psychological intervention to improve nutrition in patients with HNC who are receiving RT. The intervention provides a means to ameliorate malnutrition and the important related outcomes and consequently should be incorporated into standard care for patients receiving RT for HNC.

Effect of early and intensive nutrition care, delivered via telephone or mobile application, on quality of life in people with upper gastrointestinal cancer: study protocol of a randomised controlled trial.

BACKGROUND: A major challenge for those living with cancers of the upper gastrointestinal tract (oesophagus, stomach and pancreas), is the impact of the disease and treatment on nutritional status and quality of life. People with cancer and malnutrition have a greater risk of morbidity and mortality. Nutrition intervention is recommended to commence immediately in those who are malnourished or at risk of malnutrition. Novel cost-effective approaches that can deliver early, pre-hospital nutrition intervention before usual hospital dietetic service is commenced are needed. Linking clinicians and patients via mobile health (mHealth) and wireless technologies is a contemporary solution not yet tested for delivery of nutrition therapy to people with cancer. The aim of this study is to commence nutrition intervention earlier than usual care and evaluate the effects of using the telephone or mHealth for intervention delivery. It is hypothesised that participants allocated to receive the early and intensive pre-hospital dietetic service will have more quality-adjusted life years lived compared with control participants. This study will also demonstrate the feasibility and effectiveness of mHealth for the nutrition management of patients at home undergoing cancer treatment. METHODS: This study is a prospective three-group randomised controlled trial, with a concurrent economic evaluation. The 18 week intervention is provided in addition to usual care and is delivered by two different modes, via telephone (group 1) or via mHealth (group 2), The control group receives usual care alone (group 3). The intervention is an individually tailored, symptom-directed nutritional behavioural management program led by a dietitian. Participants will have at least fortnightly reviews. The primary outcome is quality adjusted life years lived and secondary outcomes include markers of nutritional status. Outcomes will be measured at three, six and 12 months follow up. DISCUSSION: The findings will provide evidence of a strategy to implement early and intensive nutrition intervention outside the hospital setting that can favourably impact on quality of life and nutritional status. This patient-centred approach is relevant to current health service provision and challenges the current reactive delivery model of care.

Association of Sun Exposure, Skin Colour and Body Mass Index with Vitamin D Status in Individuals Who Are Morbidly Obese.

Vitamin D deficiency is a common issue, particularly in obese populations, and is tested by assessing serum 25(OH)D concentrations. This study aimed to identify factors that contribute to the vitamin D status in fifty morbidly obese individuals recruited prior to bariatric surgery. Data collected included serum 25(OH)D concentrations, dietary and supplement intake of vitamin D, sun exposure measures, skin colour via spectrophotometry, and genotype analysis of several single nucleotide polymorphisms in the vitamin D metabolism pathway. Results showed a significant correlation between serum 25(OH)D concentrations and age, and serum 25(OH)D and ITAC score (natural skin colour). Natural skin colour accounted for 13.5% of variation in serum 25(OH)D, with every 10° increase in ITAC score (i.e., lighter skin) leading to a 9 nmol/L decrease in serum 25(OH)D. Multiple linear regression using age, ITAC score, and average UV index in the three months prior to testing, significantly predicted serum 25(OH)D concentrations (R² = 29.7%). Single nucleotide polymorphisms for all vitamin D genes tested, showed lower serum 25(OH)D for those with the rare genotype compared to the common genotype; this was most pronounced for fok1 and rs4588, where those with the rare genotype were insufficient (<50 nmol/L), and those with the common genotype were sufficient (≥50 nmol/L). Assessing vitamin D status in individuals with morbid obesity requires testing of 25(OH)D, but potential risk factors for this population include natural skin colour and age.

Vitamin D: Australian dietitian's knowledge and practices.

AIM: To survey dietitians on their knowledge and practices regarding vitamin D (VitD) intake, sources, supplementation and effect on disease state. METHODS: An online survey was disseminated to members of the Dietitian Association Australia via the weekly online state newsletter during April 2015. Response rate was 3%, with 134 respondents completing the survey. The survey included questions about knowledge and current practices. Descriptive statistics were used to analyse the results. RESULTS: Dietitians have good knowledge regarding dietary sources of VitD and roles in the body, but there is confusion around supplement doses for treatment and prevention of deficiency and sun exposure guidelines. CONCLUSIONS: Dietitians are well positioned to provide patients with advice on VitD supplementation and sun exposure practices, but not all are confident to provide this care. There is a need for clear and well-disseminated guidelines for VitD management by dietitians.
