Those with peripheral arterial disease (PAD) require important considerations with respect to food and nutrition, owing to advanced age, poor diet behaviours and immobility associated with the disease process and co-morbid state. These considerations, coupled with the economic effectiveness of medical nutrition therapy, mandate that dietetic care plays a vital role in the management of PAD. Despite this, optimising dietetic care in PAD remains poorly understood. This narrative review considers the role of medical nutrition therapy in every stage of the PAD process, ranging from the onset and initiation of disease to well established and advanced disease. In each case, the potential benefits of traditional and novel medical nutrition therapy are discussed.
Background: As the need for health care services rise, alternative service delivery models such as student-led health interventions become attractive alternatives to alleviate the burden on healthcare. Predominantly, studentled health interventions were free clinics servicing socially disadvantaged communities in the USA. A 2015 systematic review identified that students value these student-run clinics and reported skill and knowledge attainment from participating. Previous research has reported on patient satisfaction outcomes, but less frequently about the clinical outcomes patients accrue from these student-delivered services. As cardiovascular disease is the leading cause of death worldwide, this review aimed to explore the effectiveness of student-led health interventions through examining their impact on objective clinical outcomes, using the case of patients at risk of, or with, cardiovascular disease. Methods: A systematic literature search was conducted in eight electronic databases to identify student-led health interventions conducted on adults with a cardiovascular disease risk factor or established cardiovascular disease, and a clinical outcome of interest. Through double-blinded screening and data extraction, sixteen studies were identified for synthesis. Results: The majority of student-led health interventions for patients at risk of cardiovascular disease demonstrated a positive impact on patient health. Statistically significant changes amongst patients at risk of cardiovascular disease appeared to be associated with student-led individualised intervention or group-based interventions amongst patients with diabetes or those who are overweight or obese. The evidence was of moderate quality, as included studies lacked a control group for comparison and detail to enable the intervention to be replicated. Conclusions: Future research applying a student-led health intervention through a randomised control trial, with rigorous reporting of both student and patient interventions and outcomes, are required to further understand the effectiveness of this alternative service delivery model.
The COVID-19 pandemic coincided with a multi-national federally funded research project examining the potential for health and care services in small rural areas to identify and implement innovations in service delivery. The project has a strong focus on electronic health (eHealth) but covers other areas of innovation as well. The project has been designed as an ethnography to prelude a realist evaluation, asking the question under what conditions can local health and care services take responsibility for designing and implementing new service models that meet local needs? The project had already engaged with several health care practitioners and research students based in Canada, Sweden, Australia, and the United States. Our attention is particularly on rural communities with fewer than 5,000 residents and which are relatively isolated from larger service centres. Between March and September 2020, the project team undertook ethnographic and auto-ethnographic research in their own communities to investigate what the service model responses to the pandemic were, and the extent to which local service managers were able to customize their responses to suit the needs of their communities. An initial program theory drawn from the extant literature suggested that “successful” response to the pandemic would depend on a level of local autonomy, “absorptive capacity,*” strong service-community connections, an “anti-fragile†” approach to implementing change, and a realistic recognition of the historical barriers to implementing eHealth and other innovations in these types of rural communities. The field research in 2020 has refined the theory by focusing even more attention on absorptive capacity and community connections, and by suggesting that some level of ignorance of the barriers to innovation may be beneficial. The research also emphasized the role and power of external actors to the community which had not been well-explored in the literature. This paper will summarize both what the field research revealed about the capacity to respond well to the COVID-19 challenge and highlight the gaps in innovative strategies at a managerial level required for rapid response to system stress.*Absorptive Capacity is defined as the ability of an organization (community, clinic, hospital) to adapt to change. Organizations with flexible capacity can incorporate change in a productive fashion, while those with rigid capacity take longer to adapt, and may do so inappropriately.†Antifragility is defined as an entities' ability to gain stability through stress. Biological examples include building muscle through consistent use, and bones becoming stronger through subtle stress. Antifragility has been used as a guiding principle in programme implementation in the past.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
