Doctors identify regulatory barriers for their patients with type 2 diabetes to access the nutritional expertise of dietitians

Establishing consensus on nutrition competencies for medicine: a Delphi study

Background

Significant research, regulatory bodies and even governmental resolutions have identified meaningful nutrition education for medical and other healthcare professionals as a priority. Doctors are well placed to provide nutrition care, yet nutrition education in medicine remains inadequate regardless of country, setting, or year of training. There remains a need to establish an accepted benchmark on nutrition competencies for medicine, as without consensus standards there is little likelihood of uniform adoption.

Objective

This study aimed to establish consensus on nutrition competencies using a Delphi process to inform a framework for nutrition education in medicine.

Methods

A three-round modified online Delphi survey of experts in healthcare practice, education and training, and experts by experience (service users) was conducted to provide a comprehensive consensus on nutrition competencies for medical practice.

Results

Fifty-two experts (15.1% response rate) participated in Round 1, 42 completed Round 2 and 47 completed Round 3. Participants included medical professionals, dietitians, academics working in health professions education and policymakers from Australia, New Zealand, the UK and Northern Ireland. Twenty-seven service users (57.5% response rate) completed the Round 1 questionnaire, 19 completed Round 2 and 16 completed Round 3. By consensus, 25 nutrition competencies for medicine were defined. The service user panel identified an additional seven skills and attributes considered important in the receipt of nutrition care. Competencies that achieved consensus broadly fell into themes of team-based care, communication, professionalism (eg, attributes) and health promotion and disease prevention. This informs broad skills that may be taught in a nutrition context but could be included in other domains.

Conclusions

The findings suggest doctors need the knowledge and skills to consider the findings from nutrition screening and assessment, coordinate nutrition care when an individual may benefit from further assessment or intervention and provide support for advice delivered by other experts as part of a multidisciplinary approach.

A web-based low carbohydrate diet intervention significantly improves glycaemic control in adults with type 2 diabetes: results of the T2Diet Study randomised controlled trial

BACKGROUND/OBJECTIVES

In people with type 2 diabetes mellitus (T2DM), low carbohydrate diets (LCD), defined as 10-<26% total energy intake from carbohydrate, have indicated improved glycaemic control and clinical outcomes. Web-based interventions can help overcome significant challenges of accessibility and availability of dietary education and support for T2DM. No previous study had evaluated a web-based LCD intervention using a randomised controlled trial (RCT) design. The objective of this study was to assess whether a web-based LCD programme provided in conjunction with standard care improves glycaemic control in adults with T2DM.

SUBJECTS/METHODS

A 16-week parallel RCT was conducted remotely during Covid-19 among the general community, recruiting adults with T2DM not on insulin aged 40-89 years. Participants were randomly assigned (1:1) to standard care plus the web-based T2Diet healthy LCD education programme (intervention) or standard care only (control). The primary outcome was haemoglobin A1c (HbA1c). Secondary outcomes were weight, body mass index (BMI), anti-glycaemic medication, dietary intake, and self-efficacy. Blinded data analysis was conducted by intention-to-treat.

RESULTS

Ninety-eight participants were enrolled, assigning 49 to each group, with 87 participants (n = 40 intervention; n = 47 control) included in outcome analysis. At 16 weeks, there was a statistically significant between-group difference favouring the intervention group, with reductions in HbA1c -0.65% (95% CI: -0.99 to -0.30; p < 0.0001), weight -3.26 kg (p < 0.0001), BMI -1.11 kg/m2 (p < 0.0001), and anti-glycaemic medication requirements -0.40 (p < 0.0001), with large effect sizes Cohen's d > 0.8.

CONCLUSION

This study demonstrated that as an adjunct to standard care, the web-based T2Diet programme significantly improved glycaemic control and clinical outcomes in adults with T2DM. In addition, the results highlight the potential to improve access and availability for people with T2DM to achieve glycaemic control and improved health through web-based dietary education and support.

The Emerging Prevalence of Obesity within Families in Europe and its Associations with Family Socio-Demographic Characteristics and Lifestyle Factors; A Cross-Sectional Analysis of Baseline Data from the Feel4Diabetes Study

The Feel4Diabetes study is a type 2 diabetes prevention program that recruited 12,193 children [age: 8.20 (±1.01) years] and their parents from six European countries. The current work used pre-intervention data collected from 9576 children-parents pairs, to develop a novel family obesity variable and to examine its associations with family sociodemographic and lifestyle characteristics. Family obesity, defined as the presence of obesity in at least two family members, had a prevalence of 6.6%. Countries under austerity measures (Greece and Spain) displayed higher prevalence (7.6%), compared to low-income (Bulgaria and Hungary: 7%) and high-income countries (Belgium and Finland: 4.5%). Family obesity odds were significantly lower when mothers (OR: 0.42 [95% CI: 0.32, 0.55]) or fathers (0.72 [95% CI: 0.57, 0.92]) had higher education, mothers were fully (0.67 [95% CI: 0.56, 0.81]) or partially employed (0.60 [95% CI: 0.45, 0.81]), families consumed breakfast more often (0.94 [95% CI: 0.91 0.96]), more portions of vegetables (0.90 [95% CI: 0.86, 0.95]), fruits (0.96 [95% CI: 0.92, 0.99]) and wholegrain cereals (0.72 [95% CI: 0.62, 0.83]), and for more physically active families (0.96 [95% CI: 0.93, 0.98]). Family obesity odds increased when mothers were older (1.50 [95% CI: 1.18, 1.91]), with the consumption of savoury snacks (1.11 [95% CI: 1.05, 1.17]), and increased screen time (1.05 [95% CI: 1.01, 1.09]). Clinicians should familiarise themselves with the risk factors for family obesity and choose interventions that target the whole family. Future research should explore the causal basis of the reported associations to facilitate devising tailored family-based interventions for obesity prevention.

Dichotomising the risk of hyperglycaemia into diabetes and prediabetes may render a disservice to patient care

Cardiovascular diseases (CVDs) are the leading cause of death worldwide, accounting for one-third of global mortality. Prediabetes increases the risk of CVDs as well as several other conditions, yet people with prediabetes may not seek intervention, thinking that they do not have diabetes, as the risk of progression may have not been emphasised by the healthcare professional. Accumulating evidence indicates that hyperglycaemia represents a continuum of CVD risk and dichotomising the risk into type 2 diabetes and prediabetes may deter early clinical intervention. It is proffered that the term 'prediabetes' is a misnomer that may disguise a serious condition, fostering complacency and undermining its prognostic significance.

Exploring stakeholder experiences of dietetic service and care delivery: A systematic qualitative review

BACKGROUND

There is limited understanding of patients' and healthcare professionals' perceptions and experiences of receiving and delivering dietetic care, respectively. This systematic review of the literature used qualitative synthesis to explore the perceptions and experiences of multiple stakeholders involved in the delivery of nutrition care and dietetic service.

METHODS

MEDLINE, Embase, CINAHL, Cochrane Library, Scopus, ISI Web of Science, PsycINFO and ProQuest were systematically searched. Study characteristics and perceptions of stakeholders regarding nutrition care services were extracted. Qualitative synthesis was employed and thematic analysis conducted.

RESULTS

Five themes were identified from 44 studies related to stakeholders' perceptions of dietetic services. Studies included quantitative, qualitative and mixed methods involving patients, families, dietitians and other healthcare professionals. The themes were (1) patients desiring a personalised approach to nutrition care; (2) accessing dietetic service; (3) perceived impact of nutrition care on the patient; (4) relationships between stakeholders; and (5) beliefs about nutrition expertise. Two themes were specific to patients; these were the desire for individualised care and the impact of nutrition care. Within each theme perceptions varied with patients' views often contrasting with those of dietetic service providers.

CONCLUSIONS

Experiences of dietetic service do not always meet stakeholder expectations which impacts on patient engagement. Seeking stakeholder input is imperative to design dietetic services that engage patients in positive and supportive clinical partnerships.

Attitudes, work roles and barriers to nutrition care - Interviews with Australian and UK-based medical doctors

BACKGROUND

Poor diet is implicated in multiple chronic diseases. While doctors may be well-placed to facilitate nutrition care, nutrition remains a low priority in medical education internationally. Consensus is required on nutrition competencies as a benchmark for education with a regulatory framework to ensure implementation. The aim of this qualitative study was to explore work roles, attitudes, barriers, and enablers in the delivery of nutrition care amongst a cohort of Australian and UK doctors.

METHODOLOGY

Semi-structured interviews were conducted with primary care doctors/GPs (n=14) and medical specialists (n=8) based in Australia and the United Kingdom to explore work roles, attitudes, barriers and enablers in the delivery of nutrition care.

RESULTS

Framework analysis identified five key themes: 1) Knowledge and skills in nutrition to support medical nutrition care, 2) The delivery of nutrition education, 3) Multidisciplinary and interdisciplinary care, 4) Systemic barriers and facilitators to care and, 5) The need for a paradigm shift. Participants acknowledged nutrition as an important component of medical care but recognised they are currently ill-equipped to support such care, identifying limitations to the systems supporting integrated care. Participants identified that nutrition sits within both a health promotion and medical/treatment model, but they currently work only within the latter.

CONCLUSION

Participants highlighted a lack of knowledge and training around nutrition, without which change is not possible. Efforts to improve the nutrition capacity of the medical workforce must be matched by increased investments in primary prevention, including nutrition - a paradigm shift from the medical model.

How to Implement the 3-Phase FODMAP Diet Into Gastroenterological Practice

Background/Aims

The 3-phase fermentable oligo-, di-, mono-saccharides, and polyols (FODMAP) diet has shown a high level of efficacy in irritable bowel syndrome, largely based on dietitian delivered education. However, access to dietitians can be limited, and challenges exist when applying the diet to a wide range of cultures, such as limited FODMAP analysis of local foods. This review aims to discuss ways to optimally use the FODMAP diet in practice in a wide range of cultures, directed at gastroenterologists from a dietitian's perspective.

Methods

Recent literature was analysed via search databases including Medline, CINAHL, PubMed and Scopus.

Results

The dietetic process involves detailed assessment and follow-up through the 3 stages of the FODMAP diet (restriction, re-introduction, and long-term maintenance). Emerging evidence suggests the diet can be delivered by other health professionals such as the gastroenterologist or nurse, but training on how to do so successfully would be needed. Self-guided approaches through use of technology or specialised food delivery services may be an alternative when dietitians are not available, but efficacy data is limited. Regardless of delivery mode, nutritional and psychological risks of the diet must be mitigated. Additionally, culturally appropriate education must be provided, with accommodations necessary when the FODMAP content of local foods are unknown.

Conclusion

While the diet has shown improved irritable bowel syndrome outcomes across studies, it is important to acknowledge the essential role of dietitians in implementing, tailoring, and managing the diet to achieve the best outcome for each individual.

Prevalence of Childhood Obesity by Country, Family Socio-Demographics, and Parental Obesity in Europe: The Feel4Diabetes Study

The Feel4Diabetes study recruited 12,193 children (age: 8.20 ±1.01 years) and their parents from six European countries as part of the broader attempt to prevent type 2 diabetes. The current work collected data pre-intervention to identify the prevalence of childhood obesity by country and describe its association with socio-demographic characteristics and parental obesity status. One in four children were overweight or obese, and one in four families had at least one obese parent. Multivariate logistic regression examined the associations between childhood obesity, family socio-demographics, and parental obesity status. Children had a higher chance of being overweight or obese if they were living in “low income” countries (OR: 2.11, 95% CI: 1.62, 2.74) and countries “under economic crisis” (OR: 2.48, 95% CI: 1.89, 3.24) compared to “high-income” countries; if their fathers completed fewer than nine years of education (OR: 2.16, 95% CI: 1.54, 3.05) compared to children whose fathers had a higher level (>14 years) of education; and if one (OR: 2.46, 95% CI: 0.32, 0.62) or both of their parents (OR: 6.83, 95% CI: 5.15, 9.05) were obese. Future childhood obesity prevention-programs should target the whole family while taking into consideration the socioeconomic and weight status of parents. Future research should examine these associations in more countries and in socio-demographically diverse populations in order to facilitate the generalisability of the present study’s findings.
