Evaluating nurses' knowledge and patients energy intake after intervention

The role of non-dietetic healthcare professionals in managing interventions among adults at risk of malnutrition: A systematic review

BACKGROUND

Malnutrition is estimated to affect over three million people in the UK resulting in serious consequences on both the individuals' health and healthcare system. While dietitians are uniquely qualified to provide nutritional interventions, they have one of the lowest workforce numbers in the NHS making it difficult to tackle the malnutrition burden alone. Thus, innovative ways of working are needed. Non-dietetic health care professionals are often involved in the identification, assessment and treatment of malnutrition and research has shown benefits of their involvement in identification and management of nutritional issues, however their role in delivering nutritional interventions has not yet been evaluated. The aim of this systematic review is to collate evidence on the potential roles and effectiveness of non-dietetic healthcare professionals in providing nutritional interventions and their impact on patient-centred outcomes in malnourished or at-risk individuals.

METHODS

Three electronic databases were searched on 10th October 2019. Titles and abstracts were initially screened, followed by full texts, against inclusion criteria and included/excluded studies by two authors independently. Data were extracted and tabulated where possible and grouped according to type of intervention and outcomes. Risk of bias and quality of evidence was assessed using the GRADE approach. Data were combined in the form of a narrative synthesis.

RESULTS

Eighteen eligible studies were included; five involved feeding assistance, 10 involved implementing individualised nutrition monitoring or care plans and three were multi-factorial interventions. Interventions took place in a range of settings including hospital and long term care facilities. Very low and low quality evidence suggests that non-dietetic HCP interventions may improve weight, percent of patients reaching estimated energy requirements, quality of life, falls and frailty rate and patient satisfaction. Very low quality evidence suggests that non-dietetic HCP interventions may not improve mid-arm circumference, energy or protein intake, activities of daily living, handgrip strength or length of hospital stay. Low quality evidence suggests that non-dietetic HCP interventions have no effect on mortality.

CONCLUSIONS

A lack of good quality evidence on the effectiveness of non-dietetic HCP delivered interventions on the management of malnutrition in adults makes it difficult to draw conclusions. However, this review has highlighted the types of interventions and potential roles of non-dietetic HCPs, providing a groundwork for further high-quality research such as feasibility studies in this area, for the effective management of malnutrition within clinical and community practice.

The effect of nutrition training for health care staff on learner and patient outcomes in adults: a systematic review and meta-analysis

Background: Nutrition training for health care staff has been prioritized internationally as a key means of tackling malnutrition; however, there is a lack of clear evidence to support its implementation. Systematic reviews in other fields of training for health care staff indicate that training strategies may have a beneficial impact on learner and patient outcomes.Objectives: We assessed whether nutrition training for health care staff caring for nutritionally vulnerable adults resulted in improved learner and patient outcomes and evaluated the effectiveness of different training strategies.Design: A systematic review of trials of nutrition training for health care staff was conducted. Six databases were searched with key terms relating to malnutrition and nutrition training. Studies were categorized according to cognitive (didactic teaching), behavioral (practical implementation of skills), and psychological (individualized or group feedback and reflection) training strategies. Where sufficient data were available, meta-analysis was performed according to study design and training strategy. All study designs were eligible. The risk of bias was evaluated in accordance with Cochrane guidance.Results: Twenty-four studies met the eligibility criteria: 1 randomized controlled trial, 4 nonrandomized controlled trials, 3 quasi-experimental trials, 13 longitudinal pre-post trials, 2 qualitative studies, and 1 cross-sectional survey. Results from a number of low-quality studies suggest that nutrition training for health care staff may have a beneficial effect on staff nutrition knowledge, practice, and attitude as well as patient nutritional intake. There were insufficient data to determine whether any particular training strategy was more effective than the others.Conclusions: In the absence of high-quality evidence, low-quality studies suggest that nutrition training for health care staff has some positive effects. However, further randomized controlled trials are required to confirm overall efficacy and to explore the impact of training strategies on learner and patient outcomes.

Nutrition training improves health workers' nutrition knowledge and competence to manage child undernutrition: a systematic review

BACKGROUND

Medical and nursing education lack adequate practical nutrition training to fit the clinical reality that health workers face in their practices. Such a deficit creates health workers with poor nutrition knowledge and child undernutrition management practices. In-service nutrition training can help to fill this gap. However, no systematic review has examined its collective effectiveness. We thus conducted this study to examine the effectiveness of in-service nutrition training on health workers' nutrition knowledge, counseling skills, and child undernutrition management practices.

METHODS

We conducted a literature search on nutrition interventions from PubMed/MEDLINE, CINAHL, EMBASE, ISI Web of Knowledge, and World Health Organization regional databases. The outcome variables were nutrition knowledge, nutrition-counseling skills, and undernutrition management practices of health workers. Due to heterogeneity, we conducted only descriptive analyses.

RESULTS

Out of 3910 retrieved articles, 25 were selected as eligible for the final analysis. A total of 18 studies evaluated health workers' nutrition knowledge and showed improvement after training. A total of 12 studies with nutrition counseling as the outcome variable also showed improvement among the trained health workers. Sixteen studies evaluated health workers' child undernutrition management practices. In all such studies, child undernutrition management practices and competence of health workers improved after the nutrition training intervention.

CONCLUSION

In-service nutrition training improves quality of health workers by rendering them more knowledge and competence to manage nutrition-related conditions, especially child undernutrition. In-service nutrition training interventions can help to fill the gap created by the lack of adequate nutrition training in the existing medical and nursing education system. In this way, steps can be taken toward improving the overall nutritional status of the child population.

Patients’ subjective symptoms, quality of life and intake of food during the recovery period 3 and 12 months after upper gastrointestinal surgery

Few studies describe patients' quality of life and their experienced symptoms during the recovery period after having undergone upper gastrointestinal surgery at 3 and 12 months. The aims of this study were to explore patients' quality of life and symptoms preoperatively and at 3 and 12 months following upper gastrointestinal surgery and to describe and compare patients' experiences of appetite, food intake, weight changes, tiredness and sleeping patterns. A descriptive and comparative quantitative design was used. Three instruments were used: the Gastrointestinal Symptom Rating Scale, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire and the Eating Dysfunction Scale. A questionnaire was used to investigate symptoms such as mood, appetite, sleep, activities and well-being. Twenty-four patients were included in the study. The major results were that anxiety levels and global health status decreased and that patients felt more disappointed after 12 months compared with after 3 months. Four patients at 3 months after surgery and eight patients at 12 months regained their weight compared with the situation before surgery. The contribution of nursing care activities focusing on the importance of food intake and the patients' current and historical medical records in relation to their health status should continue to be examined and researched over a longer period of time.

Enteral nutrition in intensive care

The aims of this descriptive study were to examine (1) nurses' perceptions of responsibility, knowledge and documentation focusing on enteral nutrition and (2) nursing practice regarding enteral feeding in the intensive care unit. Forty-four nurses in three intensive care units responded to a questionnaire (response rate 70%) and 40 bedside observations were performed. The nurses' primary source of knowledge was consultation with colleagues. Regarding responsibility, knowledge and documentation, the focus was more on planning, implementation and prevention than on the assessing phase of the nursing process. Gastric residual volumes were almost never checked, and none of the tubes were labelled. Seven out of 40 bedside observations revealed a backrest elevation of 30 degrees or more. Mean backrest elevation was 20.7 degrees. Comparisons between nurses in the three hospitals revealed significant differences. This study indicates that enteral nutritional nursing care within intensive care has its strength in planning, implementation and prevention of complications. Regarding nutritional assessment, the registered nurses (RNs) scored low. There are gaps between recommended nursing care and nursing practice regarding enteral nutrition. Knowledge and awareness of responsibilities in combination with a systematic documentation could increase the optimal nutritional care of the intensive care patient.

The reproducibility of a new dietary record routine in geriatric patients

BACKGROUND AND AIM

Malnutrition in nursing home residents is an important clinical and public health problem. Knowledge is lacking about the reproducibility of dietary recording in geriatric patients. Few studies have described water intake in this age group. The aim of this study was to test the reproducibility of a 7-day dietary record routine in a clinical setting.

METHODS

The dietary intake of 81 geriatric patients was recorded for two discrete periods of 7 consecutive days by the ward staff. The dietary record routine, which assessed both food and fluid intake, was based on standardized portion sizes and household measurements.

RESULTS

The mean daily energy intake during the first period was 7.07 MJ and 6.84 MJ during the second period, with a mean difference of 4%. Corresponding values and the mean difference for water intake from food and beverages were 1781 g, 1702 g and 4% respectively. Age, gender, diagnosis, length of stay, diets or ADL function did not influence the results. The correlation coefficient for fluid intake between the periods was 0.84 for women and 0.72 for men.

CONCLUSION

The 7-day dietary record routine seems to have a good reproducibility in assessing the intake of energy and fluids in geriatric patients.
