The impact of home enteral feeding on the daily lives of people with head and neck cancer: a metasynthesis of qualitative studies.

BACKGROUND: Home enteral feeding (HEF) may have a wider impact on peoples' daily lives beyond influencing their nutritional and clinical status. This metasynthesis aimed to determine the impact of HEF on peoples' daily lives. METHODS: Qualitative studies were included with adults, who had been diagnosed with head and neck cancer and had finished their cancer treatment, with a feeding tube in place. Medline, PubMed and Cinahl were searched (August 2009 to August 2019). Thematic synthesis was conducted to interpret findings from the included studies. The 'Confidence in the Evidence from Reviews of Qualitative research' (GRADE-CERQual) approach was used to assess the level of confidence associated with each review finding. RESULTS: Seven qualitative studies met the eligibility criteria. Four overarching themes were identified. 'Loss of life as they once knew it' encompassed loss of normality. 'Developing personal coping strategies works towards restoring a sense of normality' encapsulated active adjustment and acceptance of the feeding tube. 'Navigating the hurdles when transitioning back to eating' comprised the trials and tribulations of returning to oral intake. Overall, participants recognised that they could not have managed without the feeding tube and this is encapsulated in 'Feeding tube valued'. CONCLUSIONS: In many cases, initial feelings of change and loss as a result of HEF were replaced with empowerment, adaptation and acceptance following a period of adjustment. Despite the challenges associated with HEF, participants acknowledged its purpose as being functional, as well as reassuring. Future research should explore barriers and facilitators to self-management and patient empowerment amongst those receiving HEF.

Priority setting for adult malnutrition and nutritional screening in healthcare: a James Lind Alliance.

BACKGROUND: Malnutrition is one the greatest global health challenges of our generation, leading to the increased utilisation of healthcare resources, as well as morbidity and mortality. Research has primarily been driven by industry, academia and clinical working groups and has had little involvement from patients and carers. The project described in the present study aimed to establish a priority setting partnership allowing patients, carers and healthcare professionals an opportunity to influence the research agenda. METHODS: A national survey was conducted to gather malnutrition uncertainties and identify key issues (i.e. areas within scope where an evidence-base is lacking) from those with experience of malnutrition. Uncertainties were analysed according to themes. Similar questions were grouped and summary questions were developed. A second survey was conducted and respondents were asked to choose their 10 most important summary questions. A workshop was conducted to finalise the top 10 research priorities from the most frequently indicated uncertainties on the interim survey. RESULTS: Overall, 1128 uncertainty questions were submitted from 268 people. The interim survey had 71 responses and a list of the top 26 questions was generated for the workshop. There were 26 questions discussed, ranked and agreed by healthcare professionals, carers and patients at the workshop. The top 10 research priorities were then chosen. These included questions on oral nutritional supplements, vulnerable groups, screening, community care, use of body mass index and technology. CONCLUSIONS: The top 10 research priorities in malnutrition and nutritional screening have been identified from a robust process involving patients, carers and healthcare professionals.

The impact of living with home enteral feeding: perspectives of people who have had a diagnosis of head and neck cancer.

BACKGROUND: The number of people with head and neck cancer who are home enterally fed continues to grow each year. Insertion of a feeding tube is common place in these patients and is considered to have a detrimental effect on quality of life. The present study aimed to investigate the daily impact of home enteral feeding (HEF) from the perspective of people who have had a diagnosis of head and neck cancer. METHODS: The methodology aligned with interpretative phenomenology analysis. People who were home enterally fed, with head and neck cancer, and aged ≥18 years were recruited. Data were collected using semi-structured interviews and analysis focused on what the daily impact of HEF meant for participants. RESULTS: Data saturation was achieved after interviewing 15 participants. Five cluster themes were identified. 'Deviation from the norm' encompassed change and loss of normality. 'Regaining control leading to empowerment' encompassed participant empowerment through development of new skills and adjusting the feeding regime. 'Creating a new normal' involved making adjustments to facilitate inclusion and participation. 'External modifiers of the HEF experience' and 'internal modifiers of the HEF experience' encompassed the identification of external and internal HEF factors that influenced HEF adaptation. CONCLUSIONS: HEF was found to influence peoples' daily lives substantially and required extensive adjustments for individuals to find a new normal. A greater level of interpretation was provided beyond the current evidence-base for this group. Policymakers and clinicians should recognise the wider impact of HEF and ensure that this awareness is embedded in clinical practice.

Practical measurement of body composition using bioelectrical impedance, air displacement plethysmography and ultrasound in stable outpatients with short bowel syndrome receiving home parenteral nutrition: comparison of agreement between the methods.

BACKGROUND: People diagnosed with intestinal failure (IF) as a result of short bowel syndrome are dependent on home parenteral nutrition (HPN). Measuring nutritional status is essential for monitoring treatment. The present study aimed to determine the agreement and feasibility of three methods bioelectrical impedance analysis (BIA), ultrasound and air displacement plethysmography (ADP) for measuring body composition in people receiving HPN. METHODS: Body composition data were collected from patients attending an IF clinic. RESULTS: There were 50 participants recruited and data were collected for BIA (n = 46), ultrasound (n = 49) and ADP (n = 9). Numbers for ADP were much lower because of a lack of participant uptake. Fat-free mass (FFM) measured by BIA and ultrasound in comparison to ADP was found to have good intraclass correlation (ICC) 0.791 (95% confidence interval (CI) CI  -0.21 to 0.96) and a moderate ICC 0.659 [95% (CI) -0.27 to 0.92], respectively. Fat mass (FM) measured by both BIA and ultrasound in comparison to ADP was found to have moderate ICC 0.660 (95% CI -0.28 to 0.92) and poor ICC -0.005 (95% CI -0.73 to 0.65), respectively. CONCLUSIONS: Compared to ADP, BIA indicated moderate to good agreement for measuring body composition, whereas ultrasound indicated far less agreement, particularly when measuring FM. The lack of uptake of ADP suggests that participants found the Bodpod (COSMED Srl, Shepperton, UK) unfavourable. Considering that ultrasound has limited agreement and ADP was not the preferred option for participants, BIA shows some potential. However, the difference between ADP and BIA was larger for FM compared to FFM, which needs to be considered in the clinical setting.

An exploration of food and the lived experience of individuals after treatment for colorectal cancer using a phenomenological approach.

BACKGROUND: There is a paucity of qualitative literature investigating people's experiences of food and nutrition after treatment for cancer. The present study aimed to explore people's relationships with food and nutrition throughout their colorectal cancer journey. METHODS: In-depth semi-structured interviews were conducted with 25 participants who had undergone surgery for colorectal cancer. The study design was informed by principles of phenomenology. Data were collected then transcribed and analysed using an inductive coding process and a thematic analysis to allow the themes to highlight people's lived experiences. RESULTS: Data enabled five primary themes to be drawn including: 'appetite swings', 'emotions on a changing physicality', 'the medicalisation of food', 'taking control of symptom management' and a cross-cutting theme 'drivers and vehicles for action'. Feelings and emotions described by participants around their relationship with food and nutritional status often guided decisions on what was eaten more than objective nutritional measure or dietary advice. Participants used weight changes, appetite and food as barometers to measure their overall recovery. Food was an area over which people exhibited control of their lives and they could quantify, in measurable units, their overall well-being and rehabilitation. They did this either by using the currency of body weight in pounds or the size of portions eaten. CONCLUSIONS: Appetite, weight and symptoms influenced dietary intake substantially and were poignant issues affecting people's lives. The relationship people have with food determines their eating habits and an understanding of the essences and nuances of their experiences is essential to enable the delivery of patient-centred care.

An explorative study of the views and experiences of food and weight loss in patients with operable pancreatic cancer perioperatively and following surgical intervention.

PURPOSE: Malnutrition and weight loss are highly prevalent in patients with pancreatic cancer. However, little is known about how patients experience such changes after completion of a surgery. The aim of this study was to explore the views and experiences about weight loss and food in patients with operable pancreatic cancer perioperatively and following surgical treatment. METHODS: An exploratory study underpinned by hermeneutic phenomenological philosophy was conducted. Thirteen post-surgery patients with pancreatic cancer were recruited from a National Health Service (NHS) Trust in the north of England. Sampling was purposive and data were collected using semi-structured in-depth interviews. Each interview was digitally recorded, transcribed verbatim and analysed using NVivo 8. RESULTS: Six themes emerged from the data that represented the patients' views and experience of foods and weight loss after surgery: "struggling with weight loss", "being pressured to eat", "experiences with nutrition support therapy", "perception of the role of the dietitians", "lacking appropriate dietary instructions" and "road to recovery". CONCLUSIONS: The study has found that sufficient dietary advice, appropriate nutrition support and patient self-management are significant factors that affect how people recover from surgery for pancreatic cancer. Further work is required to understand the nature and effect of weight loss in surgical patients with pancreatic cancer and the role of food in their weight management.

A systematic review and meta-analysis of the effects of community use of oral nutritional supplements on clinical outcomes.

The impact of oral nutritional supplements (ONS) on patients with complications (disease related morbidity) requires further exploration. This systematic review included 44 randomised controlled trials (RCT) (29 RCT surgical, 15 RCT medical patients) examining the effect of ONS in community settings on the incidence of complications (n = 716, mean age 67 years, range 35-87). ONS (mean intake 588 kcal/day, range 125-1750; protein 22 g/day, range 0-54; mean energy from protein 22 %, range 0-54) were prescribed for a mean 74 days, range 5-365. Most RCT (77 %) reported fewer complications in the ONS group versus control. Meta-analysis (39 RCT) showed ONS consumption reduced complications including infections, pressure ulcers, wound and fracture healing (OR 0.68, 95 % CI 0.59,0.79; p<0.001). Results showed reductions when ONS were used in hospital and community settings (OR 0.72, 95 % CI 0.59,0.87; p = 0.001) or just in the community (OR 0.65, 95 % CI 0.52, 0.80; p<0.001). Reductions in complications were only seen with high ONS adherence ≥ 80 % (OR 0.63, 95 % CI 0.48,0.83; p = 0.001) and ready-to-drink ONS (OR 0.69, 95 % CI 0.60,0.81; p<0.001). This systematic review and meta-analysis show community-based use of ONS in addition to the diet substantially reduces the incidence of complications. The diversity of ONS, patient populations and complication outcomes within the trials included in this review mean further research is warranted.

A multi-national survey of experience and attitudes towards commencing home parenteral nutrition for patients with advanced cancer.

INTRODUCTION: Advanced cancer (AC) is increasingly an indication for home parenteral nutrition (HPN) but an area with possible variation in practice between geographical locations. The aims of this study are to explore the views and experiences of international multi-disciplinary teams to determine opinions and practices. METHODS: An online questionnaire was developed with members of the Home Artificial Nutrition and Chronic Intestinal Failure interest group of the European Society for Clinical Nutrition and Metabolism (ESPEN) and distributed to colleagues involved in managing patients with AC on HPN. RESULTS: A total of 220 responses were included from 5 continents including 36 countries, with 90% of all responses from Europe. Predicted survival was a key factor influencing the decision to commence HPN for most respondents 152/220 (75%), with the majority of participants reporting that patients should have a predicted survival of ≥3 months if considered for HPN (≥3 months: n = 124, 56% vs. <3 months: n = 47, 21%, p < 0.001). However, most respondents were not confident about predicting overall survival in more than 50% of cases (confident n = 40, 23% vs not confident n = 135, 77%, p < 0.001). Barriers to utilising HPN in AC included colleagues' objections (n = 91, 46%), lack of local expertise (n = 55, 28%) and funding restrictions (n = 34, 17%). CONCLUSIONS: Significant consensus was observed regarding AC as indication for HPN, while areas of variation exist. Survival prognostication is often used as an indication for commencing HPN in people with AC, although the majority of respondents were not confident in prognosticating, suggesting better clinical prognostication tools will be of assistance. Further studies are also required to better understand the obstacles faced by clinical teams to commencing HPN that may explain variations in clinical practice between countries, as well as adressing variation in funding.

An unblinded randomised controlled trial of preoperative oral supplements in colorectal cancer patients.

BACKGROUND: Perioperative oral supplementation has been shown to reduce post-operative complications. However, the use of preoperative standard oral supplements in a cohort of colorectal cancer patients has not been evaluated. The present study examined whether preoperative supplements are beneficial in this group. METHODS: In a randomised controlled trial, patients were assigned to receive 400 mL of oral supplement and dietary advice or dietary advice alone. Primary outcome was the number of post-operative complications. One hundred and twenty-five patients were recruited (59 randomised to the intervention group and 66 to the control group) and nine were excluded. RESULTS: In the intervention group, 24 (44%) patients had a complication compared to 26 (42%) in the control group (P = 0.780). In the intervention and control groups, there were eight (15%) and 16 (25%) surgical site infections, respectively (P = 0.140) and seven (13%) and 11 (17%) chest infections, respectively (P = 0.470). Subgroup analysis for hypothesis generation included 83 (71%) weight-losing patients, where there was a significant reduction in surgical site infections using the Buzby definition (P = 0.034), although this was not the case for the Centre for Disease Control definition (P = 0.052). CONCLUSIONS: There was no evidence that preoperative supplements were beneficial in reducing the number of complications, although there may be some benefit for surgical site infections in selected weight-losing preoperative patients.

Nutritional status of preoperative colorectal cancer patients.

BACKGROUND: The present study aimed to determine the extent of malnutrition in preoperative colorectal cancer patients. Malnutrition has been shown to affect post-operative outcome, so it would be beneficial to identify those who are malnourished or who are at risk of becoming so preoperatively. We examine whether weight loss is related to the length of stay or changes in fat free mass. METHODS: Patients were enrolled consecutively from outpatients 2-4 weeks prior to surgery. Assessments included body mass index, percentage weight loss, dynamometry, Malnutrition Universal Screening Tool, Subjective Global Assessment and bioelectrical impedance. Cancer staging and hospital length of stay were recorded. RESULTS: One hundred and thirty-two patients were eligible and 87 enrolled. Sixty-seven patients were weight losing and 20% had lost >10% of their usual body weight. Handgrip strength was lower in malnourished patients compared to those who had not lost weight (mean 19.4 and 27.3 kg, respectively, P = 0.013). Mean (SD) fat free mass in patients with a weight loss >10% was 39.7 (13.5) kg and, in those with <10% weight loss, was 51.9 (12.0) kg (P = 0.001). This difference was not demonstrated for fat. CONCLUSIONS: Over half of these patients had lost weight prior to surgery and one in five were malnourished. Body composition measurements demonstrated that malnourished patients had significantly less fat free mass compared to patients who were not clinically malnourished. Nutritional screening would be beneficial in this group preoperatively to identify weight-losing patients at an early stage in the care pathway when they initially enter the secondary care system.

A dietary survey to determine if patients with coeliac disease are meeting current healthy eating guidelines and how their diet compares to that of the British general population.

OBJECTIVES: To assess the dietary intake of people with coeliac disease (CD) and to determine if they are meeting the current dietary reference values (DRVs). To compare dietary intakes of people with CD to the dietary intake of the general population. The nutritional contribution of gluten-free products (GFPs) and current purchasing trends was also evaluated. SUBJECTS/METHODS: 106 patients were invited to participate via post. Three-day food diary to assess intake and a short simple questionnaire that looked at purchasing trends of GFP. RESULTS: Forty-nine patients returned the food diary and 48 returned the questionnaire. Patients were found to have a low intake of energy, non-starch polysaccharides (NSPs), vitamin D and calcium. They were obtaining a significantly lower proportion of energy from fat and a significantly higher proportion of energy from protein than the DRVs (P<0.05). Intake was comparable to the general population for most nutrients, except they had a significantly greater intake of protein, a lower intake of fat and a significantly lower intake of vitamin D (P<0.05). Specialist GFP, especially those obtained on prescription, were an important source of energy, carbohydrate, NSP, calcium and iron. CONCLUSIONS: Patients with CD are at risk of having an inadequate intake of calcium, NSP and vitamin D. Specialist GFP, which were obtained on prescription, helped patients get a balanced diet and without these patients would be at an increased risk of many deficiencies.

The role of computed tomography in evaluating body composition and the influence of reduced muscle mass on clinical outcome in abdominal malignancy: a systematic review.

It is estimated that there were 3.45 million new cases and 1.75 million deaths from cancer in Europe in 2012. Colorectal cancer was one of the most common cancers, accounting for 13% of new cases and 12.2% of all deaths. Conditions causing reduced muscle mass, such as sarcopenia, can increase the morbidity and mortality of people with cancer. Computed tomography (CT) scans can provide accurate, high-quality information on body composition, including muscle mass. To date, there has been no systematic review on the role of CT scans in identifying sarcopenia in abdominal cancer. This review aimed to examine the role of CT scans in determining the influence of reduced muscle mass on clinical outcome in abdominal cancer. A systematic review of English-language articles published in 2000 or later was conducted. Articles included cohort, randomised controlled trials and validation studies. Participants were people diagnosed with abdominal cancer who had undergone a CT scan. Data extraction and critical appraisal were undertaken. Ten cohort studies met the inclusion criteria. Seven studies demonstrated that low muscle mass was significantly associated with poor clinical outcome, with six specifically demonstrating reduced survival rates. Eight studies demonstrated that a greater number of patients (27.3-66.7%) were identified as sarcopenic using CT scans compared with numbers identified as malnourished using body mass index. CT scans can identify reduced muscle mass and predict negative cancer outcomes in people with abdominal malignancies, where traditional methods of assessment are less effective.

Evaluation of adherence to a nutrition-screening programme over a 5-year period.

BACKGROUND: Nutrition screening using the Malnutrition Universal Screening Tool (MUST) was implemented for adult patients in 2006. The aim of this study was to assess adherence to the screening programme over a 5-year period after a targeted approach to training ward staff. SUBJECTS/METHODS: Following the implementation of MUST on 32 wards, regular audits were carried out. Data on completion rates at ward level were collected by nutrition link nurses and submitted electronically for collation. RESULTS: Data on MUST were collected on a total of 17 876 patients during this period. Mean percentage of patients screened with a moderate or high risk of malnutrition was 19% in those screened within 24 h after admission and 28% in those screened at 7 days. Twenty percent of patients had an uncompleted MUST score at 24 h after admission and 15% were uncompleted after 7 inpatient days. After implementation, half the hospital population were being screened on admission. However, a number of wards were neither reporting the data nor completing the screening process. Following targeted training on wards, screening rates improved in 2009 and the number of patients screened improved as ward engagement increased. CONCLUSION: Audit has been fundamental in the implementation of MUST and has allowed training, additional time and educational resources to be allocated to specific wards to facilitate improvements in screening. Lead nurse support and monitoring has improved adherence rates and facilitated an increase in the identification of patients at moderate and high risk of malnutrition.

Improving adherence to a care plan generated from the Malnutrition Universal Screening Tool.

BACKGROUND/OBJECTIVES: Recommendations state that all hospital patients should be screened for malnutrition and for each level of risk, a suitable care plan should be available. This study investigates current practice at ward level regarding adherence to a care plan generated from a nutrition screening tool, and then aims to improve basic nutritional support actions by modifying a care plan and finally evaluates change in practice. SUBJECTS/METHODS: Pro formas were completed on nutrition care plans of 100 patients. Subsequently, 7 focus groups were conducted, which included 30 ward staff and 6 dietitians. Care plans were re-designed using information from focus groups, followed by a second set of pro formas on the care plans of 103 patients. RESULTS: Themes regarding barriers and facilitators for completion of care plans were derived from the focus groups including: 'duplication', 'time pressures', 'leadership support', 'operational issues', 'document style' and 'training'. Pro formas before and after re-design showed that nutritional support actions increased from 13 (9%) to 98 (52%) for patients at moderate or severe risk of malnutrition (P=0.033). CONCLUSIONS: Focus groups allowed engagement with ward staff to explore how care plans were used, which assisted in re-designing the care plan, while the pro formas identified limitations of initial procedures and then evaluated change. Subsequently, basic nutritional support actions that resulted from screening improved. The suitability of care plans to facilitate basic nutritional support and documentation was enhanced. However, improvements are still required, emphasising the necessity for continued training and a strategic approach to the delivery of basic nutritional care.

Can we use mid upper arm anthropometry to detect malnutrition in medical inpatients? A validation study.

BACKGROUND AND AIMS: Mid upper arm anthropometry (MUAA) is often used as a measure of nutritional status to detect changes in body composition. The aim of this study was to investigate the reliability and validity of MUAA including mid arm circumference (MAC) and triceps skin fold thickness (TSFT) to determine the usefulness in clinical practice. METHOD: We measured MUAA in 158 consecutive admissions along with subjective global assessment (SGA) and body mass index (BMI). Inter- and intra-rater reliability was evaluated in an additional 50 patients. RESULTS: The sensitivity and specificity of MUAA <5th percentile was compared with SGA and BMI. MAC and TSFT had a low sensitivity and a high specificity with low positive predictive values when compared with criterion values which were BMI

Validation of a nutrition screening tool: testing the reliability and validity.

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.
