Access to cardiac rehabilitation among South-Asian patients by referral method: a qualitative study

Cardiovascular Health and Disease in the Pakistani American Population

PURPOSE OF REVIEW

This narrative review seeks to elucidate clinical and social factors influencing cardiovascular health, explore the challenges and potential solutions for enhancing cardiovascular health, and identify areas where further research is needed to better understand cardiovascular issues in native and American Pakistani populations.

RECENT FINDINGS

The prevalence of cardiometabolic disease is high not only in Pakistan but also among its global diaspora. This situation is further complicated by the inadequacy of current cardiovascular risk assessment tools, which often fall short of accurately gauging the risk among Pakistani individuals, underscoring the urgent need for more tailored and effective assessment methodologies. Moreover, social determinants play a crucial role in shaping cardiovascular health. The burden of cardiovascular disease and upstream risk factors is high among American Pakistani individuals. Future research is needed to better understand the heightened risk of cardiovascular disease among Pakistani individuals.

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.

Patient-Centered Care Experiences of First-Generation, South Asian Migrants with Chronic Diseases Living in High-Income, Western Countries: Systematic Review

BACKGROUND

First-generation migrants from South Asia account for a considerable proportion of the immigrant populations in high-income, western countries and are at a high risk of developing complex, chronic diseases such as cardiovascular disease and diabetes. Yet, previous systematic reviews have not synthesized information about the healthcare needs and preferences of such migrants and the best ways for health services to provide them with appropriate, culturally sensitive, patient-centered care. The aim of this study is to systematically review the international evidence about first-generation, South Asian migrants' healthcare experiences from the patients' perspectives.

METHODS

Five databases were searched for qualitative, quantitative, and mixed methods studies published between January 1990 and April 2020. Fourteen thousand, six hundred and forty-four papers were retrieved and screened using pre-determined eligibility criteria. Sixty-one papers were included in this narrative synthesis. Relevant qualitative findings from the included papers were thematically analyzed, and quantitative findings were summarized.

RESULTS

Five themes emerged from findings: 1) Healthcare services engaged; 2) the language barrier; 3) experiences and perceptions of healthcare advice; 4) the doctor-patient relationship; and 5) the role of patients' families in supporting access and delivery of healthcare.

CONCLUSION

The findings indicate that communication barriers reduce the cultural and linguistic appropriateness of healthcare. Potential solutions include employing healthcare staff from the same cultural background, training healthcare professionals in cultural competence, and proactively including first-generation, South Asian migrants in decision-making about their healthcare. Future research should explore South Asian migrants' experiences of multimorbidity management, continuity of care, interdisciplinary collaboration, the formation of treatment plans and goals as little to no data were available about these issues.

Differences in Clinical Measures and Outcomes in South Asians vs Caucasians Attending Cardiac Rehabilitation

Background

South Asians have a greater predisposition to cardiac events, compared to Caucasians. Although cardiac rehabilitation programs (CRPs) are known to improve outcomes, data are sparse regarding benefits acquired by South Asians vs Caucasians. The objective of the current study was to determine the outcomes of South Asian patients undergoing CRPs, compared to Caucasian patients.

Methods

This study compared baseline characteristics and outcomes in all patients attending a CRP in Edmonton, Canada with a proportionately large South Asian population.

Results

From 1998 to 2016, a total of 811 South Asians and 5406 Caucasians attended CRPs. Baseline characteristics revealed that there were more nonsmokers (73.4% vs 29.4%, P < 0.001), with a lower body mass index (26.8 ± 0.1 vs 29.6 ± 0.1, P < 0.001), but higher prevalence of diabetes (37.7% vs 20.5%, P < 0.001) in the South Asian population. Outcome measures revealed that South Asians spent less time in the CRP (6.9 weeks ± 0.1 vs 7.3 weeks ± 0.1, P < 0.001), attended the nutrition class less (36.2% vs 53.4%, P < 0.001), and had a lower 6-minute walk improvement (66.9 m vs 73.6 m, P < 0.001). Frequency of use of β-blockers (86.9% vs 86.1%, P > 0.05), antiplatelet agents (96.3% vs 97.1%, P > 0.05), angiotensin-converting enzyme inhibitors (79.9% vs 80.0%, P > 0.05), and cholesterol-lowering agents (91.4% vs 93.8%, P > 0.05) was not significantly different.

Conclusions

Although South Asians seem to be prescribed and use proven pharmacologic treatments to the same extent as Caucasians, they appeared to benefit less from CRPs. Given higher event rates in South Asians, consideration should be given to altering the delivery of CRPs to South Asians to improve their efficacy.

Atherosclerotic Cardiovascular Disease in South Asians in the United States: Epidemiology, Risk Factors, and Treatments: A Scientific Statement From the American Heart Association

South Asians (from Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka) make up one quarter of the world's population and are one of the fastest-growing ethnic groups in the United States. Although native South Asians share genetic and cultural risk factors with South Asians abroad, South Asians in the United States can differ in socioeconomic status, education, healthcare behaviors, attitudes, and health insurance, which can affect their risk and the treatment and outcomes of atherosclerotic cardiovascular disease (ASCVD). South Asians have higher proportional mortality rates from ASCVD compared with other Asian groups and non-Hispanic whites, in contrast to the finding that Asian Americans (Asian Indian, Chinese, Filipino, Japanese, Korean, and Vietnamese) aggregated as a group are at lower risk of ASCVD, largely because of the lower risk observed in East Asian populations. Literature relevant to South Asian populations regarding demographics and risk factors, health behaviors, and interventions, including physical activity, diet, medications, and community strategies, is summarized. The evidence to date is that the biology of ASCVD is complex but is no different in South Asians than in any other racial/ethnic group. A majority of the risk in South Asians can be explained by the increased prevalence of known risk factors, especially those related to insulin resistance, and no unique risk factors in this population have been found. This scientific statement focuses on how ASCVD risk factors affect the South Asian population in order to make recommendations for clinical strategies to reduce disease and for directions for future research to reduce ASCVD in this population.

Demand management for planned care: a realist synthesis

Background

The task of matching fluctuating demand with available capacity is one of the basic challenges in all large-scale service industries. It is a particularly pressing concern in modern health-care systems, as increasing demand (ageing populations, availability of new treatments, increased patient knowledge, etc.) meets stagnating supply (capacity and funding restrictions on staff and services, etc.). As a consequence, a very large portfolio of demand management strategies has developed based on quite different assumptions about the source of the problem and about the means of its resolution.

Methods

This report presents a substantial review of the effectiveness of main strategies designed to alleviate demand pressures in the area of planned care. The study commences with an overview of the key ideas about the genesis of demand and capacity problems for health services. Many different diagnoses were uncovered: fluctuating demand meeting stationary capacity; turf protection between different providers; social rather than clinical pressures on referral decisions; self-propelling diagnostic cascades; supplier-induced demand; demographic pressures on treatment; and the informed patient and demand inflation. We then conducted a review of the key ideas (programme theories) underlying interventions designed to address demand imbalance. We discovered that there was no close alignment between purported problems and advocated solutions. Demand management interventions take their starting point in seeking reforms at the levels of strategic decision-making, organisational re-engineering, procedural modifications and behavioural change. In mapping the ideas for reform, we also noted a tendency for programme theories to become ‘whole-system’ models; over time policy-makers have advocated the need for concerted action on all of these fronts.

Findings

The remainder and core of the report contains a realist synthesis of the empirical evidence on the effectiveness on a spanning subset of four major demand management interventions: referral management centres (RMCs); using general practitioners with special interests (GPwSIs) at the interface between primary and secondary care; general practitioner (GP) direct access to clinical tests; and referral guidelines. In all cases we encountered a chequered pattern of success and failure. The primary literature is replete with accounts of unanticipated problems and unintended effects. These programmes ‘work’ only in highly circumscribed conditions. To give brief examples, we found that the success of RMCs depends crucially on the balance of control in their governance structures; GPwSIs influence demand only after close negotiations on an agreed and intermediate case mix; significant efficiencies are created by direct GP access to tests mainly when there is low diagnostic yield and high ‘rule-out’ rates; and referral guidelines are more likely to work when implemented by staff with responsibility for their creation.

Conclusions

The report concludes that there is no ‘preferred intervention’ that has the capacity to outperform all others. Instead, the review found many, diverse, hard-won, local and adaptive solutions. Whatever the starting point, success in demand management depends on synchronising a complex array of strategic, organisational, procedural and motivational changes. The final chapter offers practitioners some guidance on how they might ‘think through’ all of the interdependencies, which bring demand and capacity into equilibrium. A close analysis of the implementation of different configurations of demand management interventions in different local contexts using mixed methods would be valuable to understand the processes through which such interventions are tailored to local circumstances. There is also scope for further evidence synthesis. The substitution theory is ubiquitous in health and social care and a realist synthesis to compare the fortunes of different practitioners placed at different professional boundaries (e.g. nurses/doctors, dentists/dental care practitioners, radiologists/radiographers and so on) would be valuable to identify the contexts and mechanisms through which substitution, support or short-circuit occurs.

Gender, race and cardiac rehabilitation in the United States: is there a difference in care?

Coronary heart disease is the leading cause of death within the United States, involving both genders and among all races and ethnic populations. Cardiac rehabilitation (CR) has been shown to significantly improve morbidity and mortality, and these benefits extend to individuals of both genders and all ages with coronary heart disease. Despite this, referral and participation rates remain surprisingly low. Furthermore, women and minorities have even lower referral rates than do their male and white counterparts. Over the course of this article, we will review CR referral and participation among women, as well as racial and ethnic minorities in the United States. We will also examine barriers to CR participation among these subgroups.

Cardiovascular risk among South Asians living in Canada: a systematic review and meta-analysis

BACKGROUND

South Asians represent about 3% of the Canadian population and have a higher burden of certain cardiovascular risk factors and cardiovascular disease (CVD) compared with white people. The objective of this study was to review the literature to compare cardiovascular risk factors and disease management practices among adult South Asian and white Canadians.

METHODS

We searched MEDLINE, Embase, Cochrane and Cumulative Index to Nursing and Allied Health Literature databases from their inception through Feb. 17, 2014 and the reference lists of the selected articles. English-language studies of interventions and observational studies of biological mechanisms underlying CVD risk in South Asians conducted in Canada were eligible for inclusion. Where appropriate, we used random-effects meta-analyses to integrate results comparing the CVD risk profiles of South Asian and white Canadians.

RESULTS

We included 50 articles (n = 5 805 313 individuals) in this review. Compared with white Canadians, South Asian Canadians had a higher prevalence and incidence of CVD, an increased prevalence of diabetes (odds ratio [OR] 2.25, 95% confidence interval [CI] 1.81 to 2.80, p < 0.001) and hypertension (OR 1.11, 95% CI 1.02 to 1.22, p = 0.02), lower high-density lipoprotein cholesterol levels (mean difference -0.19 mmol/L, 95% CI -0.25 to -0.13 mmol/L, p < 0.001) and a higher percentage of body fat (men: absolute mean difference 3.23%, 95% CI 0.83% to 5.62%, p = 0.008; women: absolute mean difference 4.09%, 95% CI 3.46% to 4.72%, p < 0.001). South Asian people are also more sedentary, consume higher levels of carbohydrates and are less likely to smoke tobacco (OR 0.38, 95% CI 0.24 to 0.60, p < 0.001]) than white Canadians. No differences in access to diagnostic tests, outcomes following cardiovascular surgery or use of cardiac rehabilitation programs were apparent.

INTERPRETATION

Compared with white people, South Asian people living in Canada have a higher prevalence and incidence of CVD and possess a unique cardiovascular risk profile.

A qualitative systematic review of influences on attendance at cardiac rehabilitation programs after referral

BACKGROUND

Cardiac rehabilitation and secondary prevention programs can prevent heart disease in high-risk populations. However, up to half of all patients referred to these programs do not subsequently participate. Although age, sex, and social factors are common predictors of attendance, to increase attendance rates after referral, the complex range of factors and processes influencing attendance needs to be better understood.

METHODS

A systematic review using qualitative meta-synthesis was conducted. Ten databases were systematically searched using 100+ search terms until October 31, 2011. To be included, studies had to contain a qualitative research component and population-specific primary data pertaining to program attendance after referral for adults older than 18 years and be published as full articles in or after 1995.

RESULTS

Ninety studies were included (2010 patients, 120 caregivers, 312 professionals). Personal and contextual barriers and facilitators were intricately linked and consistently influenced patients' decisions to attend. The main personal factors affecting attendance after referral included patients' knowledge of services, patient identity, perceptions of heart disease, and financial or occupational constraints. These were consistently derived from social as opposed to clinical sources. Contextual factors also influenced patient attendance, including family and, less commonly, health professionals. Regardless of the perceived severity of heart disease, patients could view risk as inherently uncontrollable and any attempts to manage risk as futile.

CONCLUSIONS

Decisions to attend programs are influenced more by social factors than by health professional advice or clinical information. Interventions to increase patient attendance should involve patients and their families and harness social mechanisms.

Participating in cardiac rehabilitation: a systematic review and meta-synthesis of qualitative data

BACKGROUND

Participation in cardiac rehabilitation (CR) benefits patients with coronary heart disease (CHD), yet worldwide only some 15–30% of those eligible attend. To improve understanding of the reasons for poor participation we undertook a systematic review and meta-synthesis of the qualitative literature.

METHODS

Qualitative studies identifying patient barriers and enablers to attendance at CR were identified by searching multiple electronic databases, reference lists, relevant conference lists, grey literature, and keyword searching of the Internet (1990–2010). Studies were selected if they included patients with CHD and reviewed experience or understanding about CR. Meta-synthesis was used to review the papers and to synthesize the data.

RESULTS

From 1165 papers, 34 unique studies were included after screening. These included 1213 patients from eight countries. Study methodology included interviews (n = 25), focus groups (n = 5), and mixed-methods (n = 4). Key reasons for not attending CR were physical barriers, such as lack of transport, or financial cost, and personal barriers, such as embarrassment about participation, or misunderstanding the reasons for onset of CHD or the purpose of CR.

CONCLUSIONS

There is a vast amount of qualitative research which investigates patients’ reasons for non-attendance at CR. Key issues include system-level and patient-level barriers, which are potentially modifiable. Future research would best be directed at investigating strategies to overcome these barriers.

Canadian Punjabi Sikh men's experiences of lifestyle changes following myocardial infarction: cultural connections

OBJECTIVE

To describe how culture underlies Canadian Punjabi Sikh men's experiences of adopting lifestyle changes following myocardial infarction (MI).

DESIGN

Qualitative, interpretive design. In-depth, individual interviews were conducted with 27 Canadian Punjabi Sikh men post-MI. Data were analysed using constant comparative methods.

RESULTS

Cultural influences were identified in Punjabi Sikh men's descriptions of their experience of adopting lifestyle changes. Actions related to self-care, rehabilitation and lifestyle change post-MI were embedded in collectivist family and community contexts. Three themes, derived from the data, were found to intertwine with these contexts; they related to food consumption, physical exercise and faith and religion.

CONCLUSION AND IMPLICATIONS

These findings highlight how collectivist ideals influence Canadian Punjabi Sikh men's adoption of lifestyle changes post-MI. The content and processes by which healthcare providers deliver heart health and rehabilitation to Canadian Punjabi Sikh men might be guided, at least in part, by the collectivist cultural practices underpinning our findings.

A narrative review of South Asian patients' experiences of cardiac rehabilitation

AIMS AND OBJECTIVES

To review the empirical literature relating to South Asian patients' experiences of cardiac rehabilitation.

BACKGROUND

Individuals of South Asian origin (originating from India, Pakistan, Bangladesh, or Sri Lanka) have increased risk of coronary heart disease-related mortality and morbidity. Low levels of cardiac rehabilitation participation have been reported among South Asian groups in several English-speaking countries.

DESIGN

Narrative review.

METHODS

Primary research evidence published in English between 1999-2010 obtained using pre-defined search criteria in electronic databases MEDLINE, CINAHL, PubMed, EMBASE, Google Scholar and PsycINFO.

RESULTS

Eleven studies met the inclusion criteria for review. Four prominent themes were identified in the literature related to: (1) exercise; (2) culture and religion; (3) programme access and structure; (4) communication and language.

CONCLUSIONS

The emerging themes distilled from the review encompass several factors associated with South Asian patients' experiences of cardiac rehabilitation that are commensurate with low uptake and poor adherence. However, few researchers have disaggregated their data by ethnic origin to describe what might best meet the needs of South Asian patients. Further research is needed to thoughtfully address issues of uptake of and compliance with cardiac rehabilitation by South Asian patients and to support the development of culturally sensitive and safe CR programmes.

RELEVANCE TO CLINICAL PRACTICE

The findings from this review can help nurses to develop guidelines for the design and delivery of culturally competent South Asian cardiac rehabilitation programmes. Important considerations related to physical exercise, language and communication preferences, religious and cultural needs and programme access and structure, need to be addressed in a culturally relevant and culturally sensitive manner to enhance the uptake and efficacy of cardiac rehabilitation for South Asian individuals.
