Barriers and facilitators to participant adherence of dietary recommendations within comprehensive cardiac rehabilitation programmes: a systematic review

Barriers and Facilitators of Center-Based Cardiac Rehabilitation Utilization in South Asian Ethnic Minorities: A META-SYNTHESIS

AIM

The aim of this review was to synthesize literature on the perceptions of South Asian ethnic minorities of the barriers and facilitators to center-based, phase II cardiac rehabilitation (CR).

METHODS

A meta-synthesis approach was used, and findings were reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was conducted from database inception dates to July 2022 using the following databases: MEDLINE, EMBASE, APA PsycINFO, Cochrane Database of Systematic Review, CINAHL, Scopus, and Web of Science. The inclusion criteria were studies that examined the barriers and/or facilitators of structured center-based CR among South Asian adult ethnic minorities. Critical appraisal of the included studies was conducted using the Mixed Methods Appraisal Tool. Findings were synthesized using a thematic synthesis approach.

RESULTS

Among the 7110 records initially retrieved only nine studies conducted in the United Kingdom or Canada met the inclusion criteria. More barriers than facilitators were studied and reported. Key barriers were the English language difficulty, fatalistic beliefs, previous bad interactions with and negative perception of health care professionals, transportation problems, work schedule conflict, safety issues, and long-distance CR centers. The facilitators included patient-preferred environment, presence of family members during exercise, family and friends support, and encouragement to change lifestyle and enroll in a CR program.

CONCLUSION

The review findings revealed that South Asian ethnic minorities encounter various barriers and facilitators to enroll and complete CR. The findings can inform researchers and clinicians in the development of interventions that are tailored to their cultural needs.

PRACTICE IMPLICATIONS

The findings can be valuable to health care professionals and policy makers in designing customized CR programs for South Asian minorities.

Daily olive oil intake is feasible to reduce trigeminal neuralgia facial pain: A pilot study

Extra virgin olive oil (EVOO) is thought to contribute to neuroprotection and, thus, may influence pain symptoms experienced by adults with demyelination-related trigeminal neuralgia (TN). This study aimed to determine the feasibility of daily intake of EVOO and its potential to alleviate facial pain of TN. Adults, self-reporting as female and affected by TN, were enrolled in a 16-week nonblinded, parallel study. After a 4-week baseline, participants were randomized to 60 mL/day EVOO or control (usual diet and no supplemental EVOO) for 12 weeks. Participants completed a daily questionnaire on pain intensity and compliance, the Penn Facial Pain Scale weekly, the 36-Item Short Form Survey monthly, and dietary assessment during baseline and intervention. Participants (n = 52; 53.3 ± 12.9 years) were recruited nationally; 42 completed the study. The EVOO group, with 90% intake compliance, showed significant decreases in the Penn Facial Pain Scale items of interference with general function, interference with orofacial function, and severity of pain from baseline, whereas the control group showed no improvements. EVOO benefit, compared with control, trended for the interference with orofacial function (P = .05). The 36-Item Short Form Survey items of role limitations resulting from emotional problems and role limitations from physical health favored EVOO. The EVOO group significantly improved their Healthy Eating Index 2015 component scores of fatty acids (primarily from increased oleic acid), sodium, and refined grains. EVOO intake of 60 mL/day was feasible for participants experiencing TN and may mitigate pain and improve quality of life. This trial was registered at clinicaltrials.gov (NCT05032573).

Time-Restricted Eating: A Novel Dietary Strategy for Cardiac Rehabilitation

Cardiac rehabilitation (CR) is a multimodal program considered to be the standard of care for secondary prevention of cardiovascular disease (CVD). The primary goals of CR are managing CVD risk factors and improving quality of life. Exercise is the cornerstone, but nutrition education delivered by registered dietitians (RDs) is a core component of CR. Yet patient constraints to adherence to dietary change and limited availability of RDs represent major barriers to the success of completion of nutrition intervention during CR. Therefore, nutritional strategies that reduce CVD risk factors, barriers to adherence, and have capacity for broad dissemination are warranted within CR programs. In this review, we propose time-restricted eating (TRE) as a nutrition strategy to improve the outcomes of CR by drawing on parallels to CVD in other populations and describe the available preliminary data on the efficacy of TRE for CVD. TRE is a dietary strategy that involves alternating periods of fasting and consumption of calories each day. We outline the feasibility, safety, and beneficial cardiometabolic impact of TRE from TRE research in other populations. We also discuss the potential for synergistic benefits of exercise when combined with TRE. Although there is currently limited research on TRE within CR programs, we highlight CR as a unique clinical setting where TRE could play a role in secondary prevention of CVD. Overall, we outline the potential of TRE as a promising nutrition strategy to enhance the benefits of CR.

The Mediterranean Diet Scale (MDS): Translation and validation of the Arabic version

OBJECTIVES

The self-administered version of the Mediterranean Diet Scale (MDS) has been developed to test the inherent characteristics of this dietary pattern in a quick and simple way, due to the need of this assessment in the clinical and research setting. This study aimed to translate and psychometrically validate the self-administered MDS in Arabic (CRBS-A).

METHODS

The original (English) version was originally translated to Arabic, followed by back-translation. Next, 10 healthcare providers, followed by 10 cardiovascular disease (CVD) patients rated the face and content validity (CV) of materials, providing input to improve cross-cultural applicability. Then, 200 patients from Saudi Arabia completed the questionnaire, of which factor structure, internal consistency, criterion and construct validity were assessed.

RESULTS

Content and face validity was supported based on experts and patients' reviews (ranges: CV scores 0.9-1.0/1.0 and clarity 3.5 to 4.5/5). Minor edits were made. Subsequent factor analysis revealed 4 factors consistent with the original version of the instrument, all internally consistent. Total CRBS-A α was 0.74. Criterion validity was confirmed by the significantly higher scores in patients who participated in CR. Construct validity was also established by significant associations between MDS scores and monthly family income, having the diagnosis of acute coronary syndrome or with a history of valve repair or replacement, being obese or having dyslipidemia.

CONCLUSIONS

Overall, these results confirm the validity and reliability of the MDS in Arabic-speaking patients.

Factors which facilitate or impede patient engagement with pulmonary and cardiac rehabilitation: a rapid evaluation mapping review

Background

There is a considerable body of systematic review evidence considering the effectiveness of rehabilitation programmes on clinical outcomes. However, much less is known about effectively engaging and sustaining patients in rehabilitation. There is a need to understand the full range of potential intervention strategies.

Methods

We conducted a mapping review of UK review-level evidence published 2017-21. We searched MEDLINE, EMBASE and the Cumulative Index to Nursing and Allied Health (CINAHL) and conducted a narrative synthesis. Included reviews reported factors affecting commencement, continuation or completion of cardiac or pulmonary rehabilitation, or an intervention to facilitate these factors. Study selection was undertaken independently by two reviewers.

Results

In total, we identified 20 review papers that met our inclusion criteria. There was a bias towards reviews considering cardiac rehabilitation, with these numbering 16. An additional 11 unpublished interventions were also identified through internet searching of key websites. The reviews included 60 identifiable UK primary studies that considered factors which affected attendance at rehabilitation; 42 considered cardiac rehabilitation and 18 considering pulmonary rehabilitation. They reported on factors from the patients' point of view, as well as the views of professionals involved in referral or treatment. It was more common for factors to be reported as impeding attendance at rehabilitation rather than facilitating it. We grouped the factors into patient perspective (support, culture, demographics, practical, health, emotions, knowledge/beliefs and service factors) and professional perspective (knowledge: staff and patient, staffing, adequacy of service provision and referral from other services, including support and wait times). We found considerably fewer reviews (n = 3) looking at interventions to facilitate participation in rehabilitation. Although most of the factors affecting participation were reported from a patient perspective, most of the identified interventions were implemented to address barriers to access in terms of the provider perspective. The majority of access challenges identified by patients would not therefore be addressed by the identified interventions. The more recent unevaluated interventions implemented during the COVID-19 pandemic may have the potential to act on some of the patient barriers in access to services, including travel and inconvenient timing of services.

Conclusions

The factors affecting commencement, continuation or completion of cardiac or pulmonary rehabilitation consist of a web of complex and interlinked factors taking into consideration the perspectives of the patients and the service providers. The small number of published interventions we identified that aim to improve access are unlikely to address the majority of these factors, especially those identified by patients as limiting their access. Better understanding of these factors will allow future interventions to be more evidence based with clear objectives as to how to address the known barriers to improve access.

Limitations

Time limitations constrained the consideration of study quality and precluded the inclusion of additional searching methods such as citation searching and contacting key authors. This may have implications for the completeness of the evidence base identified.

Future work

High-quality effectiveness studies of promising interventions to improve attendance at rehabilitation, both overall and for key patient groups, should be the focus moving forward.

Acceptability of a high-protein Mediterranean-style diet and resistance exercise protocol for cardiac rehabilitation patients: Involving service users in intervention design using a mixed-methods participatory approach

Background

Current cardiac rehabilitation (CR) practices focus on aerobic-style exercise with minimal nutrition advice. This approach may not be optimal for CR patients with reduced muscle mass and elevated fat mass. Higher protein, Mediterranean-style diets combined with resistance exercise (RE) may improve muscle mass and reduce the risk of future cardiovascular events, although such an approach is yet to be trialed in a CR population.

Objective

We explored patient perspectives on the proposed design of a feasibility study. Patients reflected on the acceptability of a proposed high-protein Mediterranean-style diet and RE protocol, emphasizing research methodology and the acceptability of the proposed recipes and exercises.

Design

We applied quantitative and qualitative (mixed methods) approaches. The quantitative approach involved an online questionnaire (n = 40) regarding the proposed study methodology and relevance. A subset of participants (n = 12) received proposed recipe guides and were asked to prepare several dishes and complete an online questionnaire regarding their experience. Another subset (n = 18) received links to videos of the proposed RE and completed a questionnaire regarding their impressions of them. Finally, semi-structured interviews (n = 7) were carried out to explore participants' impressions of the proposed diet and exercise intervention.

Results

Quantitative data indicated a high level of understanding of the intervention protocol and its importance within the context of this research. There was a high degree of willingness to participate in all aspects of the proposed study (>90%). The trialed recipes were enjoyed and found to be easy to make by a majority of participants (79 and 92.1%, respectively). For the proposed exercises 96.5% of responses agreed they would be willing to perform them and, 75.8% of responses agreed they would enjoy them. Qualitative analysis revealed that participants viewed the research proposal, diet, and exercise protocol in a positive light. The research materials were considered appropriate and well explained. Participants suggested practical recommendations for improving recipe guides and requested more individual-focused exercise recommendations, and more information on the specific health benefits of the diet and exercise protocols.

Conclusion

The study methodology and the specific dietary intervention and exercise protocol were found to be generally acceptable with some suggested refinements.
