Rural nutrition and dietetics research-Future directions

AIM

The aim of this study was to summarise key evidence from recent Australian rural nutrition research and provide recommendations for future nutrition and dietetics research with rural communities.

CONTEXT

Clear evidence demonstrates that diet plays a role in the health gap between rural and metropolitan Australia. Despite the opportunity to address the health of rural Australians through better nutrition, alarmingly low investment in nutrition and dietetics research has occurred historically, and over the past decade.

APPROACH

A review of the evidence was undertaken by rural nutrition and dietetics leaders to provide a commentary piece to inform future rural nutrition research efforts.

CONCLUSION

Establishing strong, collaborative place-based nutrition and dietetics research teams are necessary to combat the significant gaps in the scientific knowledge of solutions to improve nutrition in rural Australia. Further, dieticians and nutritionists who live in and understand the rural contexts are yet to be fully harnessed in research, and better engaging with these professionals will have the best chance of successfully addressing the nutrition-related disease disparity between rural and metropolitan Australia.

Informing online professional dietetics practice: The development and pilot testing of the Social Media Evaluation Checklist

AIM

To develop and pilot a tool to evaluate Australian dietitians' and student dietitians' ethical and professional practice using social media.

METHODS

A Social Media Evaluation Checklist was developed based on checklist development literature with a four-staged process. Stage one included a literature review and input from an expert panel to ensure content validity. Stages two and three were to ensure face validity by categorising the checklist and pilot testing the tool. Instagram profiles and posts were audited by two authors using the checklist in the final stage to analyse ethical and professional use. An account purposely created for this study was used, and the first 25 dietitian and first 25 student dietitian profiles identified using the key words 'dietitian', 'student dietitian' and 'dietitian student' and the hashtag '#australiandietitian' were reviewed.

RESULTS

A total of 50 Instagram profiles and 250 posts were audited based on seven categories; (1) financial disclosure, (2) cultural awareness, (3) evidence-based information, (4) transparency, (5) privacy/confidentiality, (6) professionalism and (7) justifiability. Areas for improvement included advertising transparency which was met in only 12% of dietitian posts, and the provision of evidence-based information, which was met in 56% of dietitian posts and 72% of student dietitian posts.

CONCLUSIONS

This study provides insight into the ethical and professional use of social media by Australian dietitians and dietetics students. With the evolving nature of social media, guidance is required. This will ensure dietitians remain, now and in the future, the credible source of nutrition information for the public.

Effectiveness and reporting of nutrition interventions in cardiac rehabilitation programmes: a systematic review

AIMS

Dietary modification is essential for the secondary prevention of cardiovascular disease. However, there are limited published evidence syntheses to guide practice in the cardiac rehabilitation (CR) setting. This systematic review's objective was to assess effectiveness and reporting of nutrition interventions to optimize dietary intake in adults attending CR.

METHODS AND RESULTS

Randomized controlled trials (RCTs) of nutrition interventions within CR were eligible for inclusion and had to have measured change in dietary intake. MEDLINE, Embase, Emcare, PsycINFO, CINAHL, Scopus, and The Cochrane Library were searched from 2000 to June 2020, limited to publications in English. Evidence from included RCTs was synthesized descriptively. The risk of bias was assessed using the Cochrane Risk of Bias 2 tool. This review is registered on PROSPERO; CRD42020188723. Of 13 048 unique articles identified, 11 were eligible. Randomized controlled trials were conducted in 10 different countries, included 1542 participants, and evaluated 29 distinct dietary intake outcomes. Five studies reported statistically significant changes in diet across 13 outcomes. Most nutrition interventions were not reported in a manner that allowed replication in clinical practice or future research.

CONCLUSION

There is a gap in research testing high-quality nutrition interventions in CR settings. Findings should be interpreted in the light of limitations, given the overall body of evidence was heterogenous across outcomes and study quality; 6 of 11 studies were conducted more than 10 years old. Future research should investigate strategies to optimize and maintain nutrition improvements for patients attending CR.

Evaluating a train-the-trainer model for scaling-up Healthy Conversation Skills training: A pre-post survey using the Theoretical Domains Framework

OBJECTIVES

Healthy Conversation Skills (HCS) training is an established method of upskilling health professionals in person-centred behaviour change communication. A Train-the-Trainer (TtT) model was adopted to scale-up delivery of HCS training. This study examined the impact of the TtT course on new Trainers' perceived barriers and enablers to delivering HCS training using the Theoretical Domains Framework (TDF).

METHODS

The TtT course was delivered in 2019-2020. Pre-training (T1) and post-training (T2) surveys collected data on barriers and enablers to delivering HCS training based on 10 TDF domains. Data were summarised using descriptive statistics, and differences between pre- and post-training scores analysed using paired t-tests.

RESULTS

Forty-six trainees participated, including 43 women and 10 Aboriginal people. Scores for nine domains increased post-training, including knowledge, skills, social and professional role/identity, beliefs about capabilities, intentions, goals, environmental context and resources, social influences, and behavioural regulation. Knowledge, beliefs about consequences and intentions were no longer barriers to delivering HCS training after participating in the TtT course.

CONCLUSIONS

The TtT model supports new Trainers by addressing barriers to delivering HCS training.

PRACTICE IMPLICATIONS

The HCS TtT model builds healthcare workforce capacity for person-centred approaches to behaviour change. The findings facilitate the refinement of the TtT course.

Current Nutrition Practice in Cardiac Rehabilitation Programs

PURPOSE

This study sought to determine current practice regarding nutrition care within cardiac rehabilitation (CR) programs, including perceived barriers and facilitators to providing nutrition care in this setting.

METHODS

A cross-sectional survey was conducted in October and November 2019. Potential participants were program coordinators, identified through the Australian Cardiovascular Health and Rehabilitation Association program directory and invited to participate via e-mail.

RESULTS

Forty-nine respondents (response rate: 13%) are included in this analysis. Programs provided group (n = 42, 86%) and/or individual (n = 25, 51%) nutrition education, and most were supported by a dietitian (63%). However, the availability of dietitians and nutrition care provided at CR was variable. For example, individual education was consistently provided at 13 programs and usually by health professionals other than dietitians. Eight programs (16%) used a formal behavior change framework for nutrition care. Generally, respondents were positive about the role of nutrition; CR coordinators perceived nutrition as a valuable component of the program, and that they had good nutrition knowledge. An identified barrier was the financial resources available to support the provision of nutrition care.

CONCLUSIONS

To ensure that patients receive the benefits of evidence-based nutrition care, program staff may require additional support, particularly regarding the use of evidence-based behavior change techniques. Key facilitators that may be leveraged to achieve this include the high value and priority that CR program coordinators place on nutrition care.

Starting from scratch: Developing and sustaining a rural research team lessons from a nutrition and dietetics case study

OBJECTIVE

To describe the development of and key factors for sustaining a rural-based research team focussed on nutrition and dietetics.

DESIGN

A longitudinal embedded case study approach with data sourced from publicly available records and observations. Case study sub-units were developed into 3 phases with analysis using theoretical propositions and pattern matching. Quantitative data were descriptively analysed.

SETTING

University of Newcastle Department of Rural Health across 4 rural sites.

PARTICIPANTS

Publicly available data sources from existing team members.

MAIN OUTCOME MEASURES

Staffing levels, research supervision, internal and external grant outcomes and peer-reviewed journal publications.

RESULT

Academic staffing has increased by 4 full-time equivalent positions over 18 years, with 6 current higher-degree research students. Key factors identified in the development of a discipline-specific research workforce included staff higher degree by research completions, longevity of staff in research-active roles, immersive rural placements with a research component and collaborations with nationally competitive researchers. Rural pilot research projects, community connections, understanding of the local context and research networks were fundamental to establishing a viable team.

CONCLUSION

Systematically investing in research that is embedded in local communities will ensure sustainability and relevance, capacity building of existing staff and an ability to problem solve at the local level. Sustained and focussed investment is needed if the current rural research workforce is to develop towards a capacity that meets current demand.

The impact of Healthy Conversation Skills training on health professionals' barriers to having behaviour change conversations: a pre-post survey using the Theoretical Domains Framework

Background

Changing people’s behaviour by giving advice and instruction, as traditionally provided in healthcare consultations, is usually ineffective. Healthy Conversation Skills (HCS) training enhances health professionals’ communication skills and ability to empower and motivate people in health behaviour change. Guided by the Theoretical Domains Framework (TDF), this study examined the impact of HCS training on health professional barriers to conducting behaviour change conversations in both clinical and non-clinical settings. Secondary aims were to i) identify health professionals’ barriers to having behaviour change conversations, and explore the ii) effect of HCS training on health professionals’ competence and attitudes to adopting HCS, iii) feasibility, acceptability and appropriateness of using HCS in their clinical and non-clinical roles, and iv) acceptability and quality of HCS training.

Methods

HCS training was conducted in October-November 2019 and February 2020. Pre-training (T1), post-training (T2) and follow-up (T3; 6-10 weeks post-training) surveys collected data on demographics and changes in competence, confidence, importance and usefulness (10-point Likert scale, where 10 = highest score) of conducting behaviour change conversations. Validated items assessing barriers to having these conversations were based on eight TDF domains. Post-training acceptability and quality of training was assessed. Data were summarised using descriptive statistics, and differences between TDF domain scores at the specific time points were analysed using Wilcoxon matched-pairs signed-rank tests.

Results

Sixty-four participants consented to complete surveys (97% women; 16% identified as Aboriginal), with 37 employed in clinical settings and 27 in non-clinical settings. The training improved scores for the TDF domains of skills (T1: median (interquartile range) = 4.7(3.3-5.3); T3 = 5.7(5.3-6.0), p < 0.01), belief about capabilities (T1 = 4.7(3.3-6.0); T3 = 5.7(5.0-6.0), p < 0.01), and goals (T1 = 4.3(3.7-5.0); T3 = 4.7(4.3-5.3), p < 0.01) at follow-up. Competence in using ‘open discovery questions’ increased post-training (T1 = 25% of responses; T2 = 96% of responses; T3 = 87% of responses, p < 0.001), as did participants’ confidence for having behaviour change conversations (T1 = 6.0(4.7-7.6); T2 = 8.1(7.1-8.8), p < 0.001), including an increased confidence in having behaviour change conversations with Aboriginal clients (T1 = 5.0(2.7-6.3); T2 = 7.6(6.4-8.3), p < 0.001).

Conclusions

Provision of additional support strategies to address intentions; memory, attention and decision processes; and behavioural regulation may enhance adoption and maintenance of HCS in routine practice. Wider implementation of HCS training could be an effective strategy to building capacity and support health professionals to use a person-centred, opportunistic approach to health behaviour change.

The Effectiveness of Randomized Controlled Trials to Improve Dietary Intake in the Context of Cardiovascular Disease Prevention and Management in Rural Communities: A Systematic Review

BACKGROUND

Dietary intake is an important modifiable risk factor for cardiovascular disease. However, to our knowledge, there are no systematic reviews of nutrition interventions in the context of cardiovascular disease prevention and management within rural communities. This is important to investigate, given the unique geographic, social, and contextual factors associated with rurality.

OBJECTIVE

Our primary objective was to systematically assess evidence on the effectiveness of randomized controlled trials to improve dietary intake in the context of cardiovascular disease prevention and management in rural communities.

METHODS

Nine electronic databases were searched from inception to June 2020, including MEDLINE, The Cochrane Library, Embase, Emcare, PsycINFO, Scopus, Rural and Remote Health, CINAHL, and AMED. Randomized controlled trials that reported results of interventions with adult, rural populations and measured change in dietary intake compared to usual care, alternative intervention, or no intervention controls were included. Included randomized controlled trials were also assessed according to the TIDieR (Template for Intervention Description and Reporting) checklist and RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework.

RESULTS

Thirteen articles reporting results of randomized controlled trials were identified. Included articles reported a range of nutrition interventions and measured 18 dietary intake outcomes. Most studies (n = 10) demonstrated effectiveness in altering at least 1 dietary intake outcome, including fruit and/or vegetable (n = 9), fiber (n = 2), Dietary Risk Assessment score (n = 2), energy, dairy, carotene, vitamin C and sodium (all n = 1). However, there was wide variation in the reporting of intervention components (according to the TIDieR checklist) and impact (according to RE-AIM framework), resulting in difficulty interpreting the "real-world" implications of these results.

CONCLUSIONS

Through this systematic review, we found limited evidence of improvement in dietary intakes due to nutrition interventions in the context of cardiovascular disease prevention and management in rural communities. Fruit and/or vegetable intakes were the most frequently reported dietary intake outcomes, and most likely to be improved across the included studies. Included studies were generally not well reported, which may hinder replication by clinicians and consolidation of the evidence base by other researchers. Given the substantial burden of cardiovascular disease experienced by those living in rural areas of developed countries, additional high-quality nutrition research that acknowledges the complexities of rural health is required.

Informing telehealth service delivery for cardiovascular disease management: exploring the perceptions of rural health professionals

Objective To explore the perceptions of rural health professionals who use telehealth services for cardiovascular health care, including the potential role of telehealth in enhancing services for this patient group. Methods Semi-structured interviews were conducted with ten rural health professionals across a range of disciplines, including medicine, nursing and allied health. All study participants were based in the same rural region in New South Wales, Australia. Results Participant responses emphasised the importance of including rural communities in ongoing dialogue to enhance telehealth services for cardiovascular care. Divergent expectations about the purpose of telehealth and unresolved technology issues were identified as factors to be addressed. Rural health professionals highlighted the importance of all stakeholders coming together to overcome barriers and enhance telehealth services in a collaborative manner. Conclusion This study contributes to an evolving understanding of how health professionals based in regional Australia experience telehealth services. Future telehealth research should proceed in collaboration with rural communities, supported by policy that actively facilitates the meaningful inclusion of rural stakeholders in telehealth dialogue. What is known about the topic? Telehealth is frequently discussed as a potential solution to overcome aspects of rural health, such as poor outcomes and limited access to services compared with metropolitan areas. In the context of telehealth and cardiovascular disease (CVD), research that focuses on rural communities is limited, particularly regarding the experiences of these communities with telehealth. What does this paper add? This paper offers insight into how telehealth is experienced by rural health professionals. The paper highlights divergent expectations of telehealth's purpose and unresolved technological issues as barriers to telehealth service delivery. It suggests telehealth services may be enhanced by collaborative approaches that engage multiple stakeholder groups. What are the implications for practitioners? The use and development of telehealth in rural communities requires a collaborative approach that considers the views of rural stakeholders in their specific contexts. To improve telehealth services for people living with CVD in rural communities, it is important that rural stakeholders have opportunities to engage with non-rural clinicians, telehealth developers and policy makers.
