Cardiac rehabilitation delivery in low/middle-income countries

Built Environment and Cardiovascular Diseases - Insights from a Global Review

PURPOSE OF REVIEW

This narrative review aims to synthesize global literature on the relationship between cardiovascular diseases (CVD) and components of built environment (green spaces, walkability, food environment, accessibility and availability of recreational and healthcare facilities, and effects of air and noise pollution).

RECENT FINDINGS

Increased green space and neighborhood walkability are associated with lower CVD mortality and morbidity; however, benefits have shown differential effects by socioeconomic status (SES). Air pollution is a leading environmental risk factor contributing to CVDs, and it disproportionately impacts low SES populations and women. Findings on relationships between food environment and CVDs are inconsistent and limited. This global review reports on the multifactorial and complex relationship between built environment and higher CVD risk and poor CVD outcomes. Future research can address an unmet need to understand this relationship with further depth and breadth, and to investigate resulting health disparities.

From surgery to recovery: Measuring success through quality of life and functional improvements after cardiac surgery

Coronary artery disease and aortic valve stenosis are highly prevalent cardiovascular diseases worldwide, resulting in substantial morbidity and mortality. Surgical interventions, such as coronary artery bypass grafting and surgical aortic valve replacement, offer significant therapeutic benefits, including enhanced postoperative quality of life (QoL) and functional capacity, which are key indicators of surgical success. This editorial reviews recent studies on postoperative QoL and functional outcomes in patients undergoing cardiac surgery. Factors such as preoperative health, age, intensive care unit stay duration, surgical risk, and perioperative complications could influence these outcomes. Cardiac rehabilitation is pivotal in enhancing patient function, reducing frailty and improving long-term QoL.

Effectiveness of virtual reality in cardiac rehabilitation patients for exercise capacity and negative emotions: A systematic review and meta-analysis

BACKGROUND

The significance of virtual reality (VR) technology as an alternative or complementary modality to traditional cardiac rehabilitation is of increasing interest. Numerous studies have examined the effects of virtual reality technology in cardiac rehabilitation patients, but the results have been inconsistent.

METHODS

We conducted a systematic search of the Cochrane Library, Web of Science, PubMed, Embase, Scopus, ProQuest, OVID, CINAHL, SinoMed, CNKI, WanFang, VIP Database, and ReadShow databases following the Program for Systematic Review and Meta-Analysis guidelines. The search included studies published up until June 30, 2024. The Cochrane Risk of Bias Tool was used to examine the methodological quality of the included randomized controlled studies. When feasible, a meta-analysis was performed to calculate the pooled effects using Review Manager (version 5.3). Otherwise, narrative summaries were performed.

RESULTS

A total of 11 studies with 1093 patients were included. The results of systematic review and meta-analysis showed that virtual reality technology improved patients' exercise capacity (mean difference: 53.26, 95% confidence interval [CI]: 45.14-61.37; P < .00001); anxiety (standardized mean difference [SMD]: -0.39, 95% CI: -0.69, -0.08, P = .01); depression (SMD: -0.48, 95% CI: -0.79, -0.17; P = .003); stress (SMD: -0.72, 95% CI: -1.03, -0.40; P < .00001); emotional tension (SMD: -0.81, 95% CI: -1.15, -0.47; P < .00001); emotional tension (SMD: -0.64, 95% CI: -0.98, -0.30; P = .0002), and intrapsychic stress (SMD: -0.56, 95% CI: -0.90, -0.23; P = .0009).

CONCLUSION

Virtual reality-based interventions can be effective in improving patients' exercise capacity and negative emotions. However, further research is needed to determine the efficacy of VR for other clinical outcomes.

Rethinking Scale-Up of Rehabilitation for Chronic Disease in Low-Resource Settings: Embracing Complexity for Contextual Impact

As the burden of chronic disease and multiple long-term conditions is increasing globally, disproportionally affecting those in low-resourced settings, there is an increasing call to action to scale effective models of care that can assist in mitigating the impact of chronic disease on functioning, activity, societal participation, and health-related quality of life. The aim of this paper is to unpack the contextual factors that have been implicitly and explicitly voiced by researchers reporting on rehabilitation interventions used to manage chronic disease in low-resourced settings. We systematically engaged the literature and applied a reflexive qualitative and systems thinking lens to unpack the contextual factors and their interplay. A total of 40 different contextual factors were derived through an iterative analysis of 144 eligible articles. The identified factors could be packaged into nine system elements or subsystems relevant to the scale-up of rehabilitation for people with chronic disease. The complexity identified encourages a focus on innovative and intersectoral approaches to address the rehabilitation needs in low-resourced settings.

Exploring the Impediments: Investigating Barriers to Participation in Phase-2 Cardiac Rehabilitation Following Coronary Artery Bypass Graft Among Thai Patients

Background

Despite the known benefits of cardiac rehabilitation (CR), the rate of participation is low following coronary artery bypass graft (CABG). The reasons for this lack of participation are unclear and there have been few studies investigating this, particularly in Asian countries. The present study aimed to address this lack of information and identify reasons for non-participation in phase-2 CR among patients who underwent CABG.

Methods

We enrolled 42 patients who underwent CABG or CABG combined with valvular heart surgery in a university hospital between October 2016 to September 2018. Patients who participated in phase-1 but not phase-2 CR were interviewed by phone following an 11-item questionnaire.

Results

The rate of participation in phase-2 CR was only 12.5%. The most frequently reported reason for non-participation was "Did not know that there was phase-2 CR" (61.9%), followed by "Transportation problems" (31%). "Unable to take leave due to work schedule" was fairly frequently reported (19%) as was "Did not participate due to chronic diseases and complications" (14.3%).

Conclusion

Our study revealed low participation in phase-2 CR, despite its well-known benefits. The primary reason identified was a lack of awareness and understanding among patients regarding phase-2 CR. This highlights the need for targeted interventions aimed at increasing knowledge and awareness of the benefits and availability of CR. Additionally, it is crucial to establish an efficient referral system that ensures seamless transitions from the initial cardiac treatment to the rehabilitation phase. Implementing these strategies is expected to boost CR participation, leading to improved patient outcomes and overall cardiac health.

Comparative efficacy and adherence of telehealth cardiac rehabilitation interventions for patients with cardiovascular disease: A systematic review and network meta-analysis

BACKGROUND

Traditional center-based cardiac rehabilitation had low adherence rates. With the increasing utilization of digital technology in healthcare services, telehealth can overcome common barriers to improve adherence, and some telehealth interventions have been proven safe and effective. However, it remains unclear which telehealth intervention types can maximize the efficacy and adherence for cardiac rehabilitation.

OBJECTIVE

To compare the effect of different types of telehealth interventions on the efficacy and adherence of patients with cardiovascular disease in cardiac rehabilitation.

DESIGN

Systematic review and network meta-analysis.

METHODS

We systematically searched PubMed, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL, ProQuest, Scopus, and Embase databases for randomized controlled trials of telehealth cardiac rehabilitation for cardiovascular disease patients from January 2013 to March 2024. The primary outcomes were peak oxygen uptake (VO2 peak) and adherence. Secondary outcomes included 6-minute walking distance, moderate-to-vigorous intensity physical activity, depression, self-reported quality of life, and patient satisfaction. The study protocol has been registered on PROSPERO (ID: CRD42023459643).

RESULTS

This network meta-analysis included 46 randomized controlled trials. The results indicated that telehealth cardiac rehabilitation improved VO2 peak, 6-minute walking distance, moderate-to-vigorous intensity physical activity, and adherence. The surface under the cumulative ranking curve (SUCRA) results showed that the Wearable Devices + Smartphone Applications (SUCRA = 86.8 %, mean rank = 1.7) was the most effective telehealth intervention for improving VO2 peak. The Smartphone Applications + Instant Communication Tools (SUCRA = 74.2 %, mean rank = 2.6) was the most effective telehealth intervention for promoting adherence.

CONCLUSIONS

Combining two or more types of telehealth interventions was found to be effective. Future efforts should prioritize conducting high-quality randomized controlled trials to identify more effective combinations with traditional cardiac rehabilitation.

The Effectiveness of Cardiac Rehabilitation Programs in Improving Cardiovascular Outcomes: Systematic Review and Meta-Analysis

Cardiovascular diseases (CVDs) are some of the most common conditions and the major contributors to death and disability globally, hence the need for proper secondary prevention interventions. Cardiac rehabilitation (CR) programs have been recognized as an essential component in the treatment of CVDs with the goal of decreasing the risk of new cardiovascular events and improving the quality of life. This systematic review and meta-analysis sought to determine the impact of CR as a form of CVD treatment on mortality, morbidity, functional capacity, and quality of life amongst the patient population. The search resulted in 12 studies that fulfilled the inclusion criteria, which included both randomized controlled trials as well as cohort studies. The meta-analysis, therefore, showed that the CR program is effective in reducing all-cause mortality (RR=0 74, 95% CI: 0.62-0. Favorable effects of intervention regarding participation measures were found in the International Classification of Functioning, Disability and Health (ICF) domains of body functions (pool standardized mean differences (SMD)= 0.55, 95% CI: 0.43-0.68). The results confirm the significance of CR programs as an essential element of secondary prevention of CVDs, stressing the ability of CR to lower mortality rates and improve patients' functional status. Despite this, the implementation of CR programs continues to be suboptimal globally for various healthcare facilities; hence the requirement for interventions to ensure that more patients incorporate the protocols and adapt uniform CR protocols.

Translation, Cultural Adaptation of the Portuguese Provider Attitudes toward Cardiac Rehabilitation and Referral (PACRR-P) Scale and Assessment of Its' Measurement Properties

BACKGROUND/OBJECTIVES

Access to cardiac rehabilitation (CR) is contingent upon physician referrals, yet these are often inadequate, particularly in low-resource settings. This multi-method study aimed to translate, culturally adapt, and validate the Portuguese version of the Provider Attitudes toward CR and Referral (PACRR-P) scale, as well as to identify key factors influencing CR referral in a Latin American context for the first time.

METHODS

The PACRR was translated into Brazilian Portuguese through a rigorous process involving independent translation, back-translation, and expert panel review to ensure face, content, and cross-cultural validity. A total of 44 Brazilian physicians completed the questionnaire, allowing for an assessment of internal consistency, criterion validity, and convergent validity.

RESULTS

The findings confirmed the face, content, and cultural validity of the 20 translated items, with a mean item clarity rating of 4.8/5. The final version included 17 of the original 19 PACRR-P items, with a Cronbach's alpha of 0.73. Referral rates were significantly associated with over one-third of the PACRR-P items, preliminarily supporting the scale's criterion validity, while correlations with the ReCaRe scores further supported its convergent validity. The most prominent barriers to referral were a lack of familiarity with CR site locations, absence of a standard referral form, and lack of automatic referral processes.

CONCLUSIONS

The PACRR's validity and reliability among Portuguese-speaking providers are preliminarily supported.

Distinctive characteristics, risk factors, and prevention of premature myocardial infarction: A narrative review

The proportion of young individuals that present with acute myocardial infarction is a major problem that keeps increasing. The specific characteristics of premature coronary artery disease and its differences between young and older individuals need to be elucidated. Although risk factors are similar in different age categories, there is a great difference in their prevalence. The vast majority of young patients are males and there is a higher prevalence of cigarette smoking, family history of premature coronary artery disease, lipid disorders, and illicit drug use, while the prevalence of hypertension and diabetes mellitus is lower. Young individuals with acute coronary syndrome usually present either with ST-segment elevation or non-ST-segment elevation myocardial infarction. It is not unusual for young patients to present with atypical symptoms to the office of primary care physicians, leading occasionally to incorrect or delayed diagnosis. Therefore, prompt and correct diagnosis is necessary to implement the specific management as quickly as possible. A literature research of studies was conducted for the last 10 years, regarding the risk factors and prevention of premature myocardial infarction. As databases, we used PubMed and peer reviewed journals. The aim of this review is to raise awareness among family medicine and primary care physicians, regarding the clinical presentation of young patients with acute myocardial infarction, to provide optimal medical attention.

Challenges and solutions to implementing cardiac rehabilitation in a low- and middle-income country

BACKGROUND

Cardiac rehabilitation (CR) remains greatly underutilized, especially in low- and middle-income countries (LMIC). It is therefore important to explore factors that contribute to this, as perceived by health-care professionals (HCPs).

RESEARCH DESIGN AND METHODS

This was a qualitative study using in-depth interviews that enrolled 18 HCPs (i.e. six each of physicians, physiotherapists, and nurses; mean experience in CR: 17.9 ± 11.8 yrs) working in cardiovascular care, and CR across private and government hospitals (both teaching and non-teaching) in India.

RESULTS

The main challenges were related to lack of referrals, perceived lack of benefit from CR, poor infrastructure within hospitals and health systems, and differences in practice. The perceived inadequacies were lack of competencies in CR, limited task sharing strategies, and ineffective utilization of existing human resources. Devising strategies to improve awareness and competencies, facilitating task sharing, and remodeling holistic care with an active CR component may be beneficial to facilitate greater implementation of CR in India.

CONCLUSIONS

Challenges, inadequacies, and solutions to implementing CR have been explored by involving various HCPs commonly involved in delivering CR across different health systems in a LMIC.

Barriers and facilitators to nutritional recommendations identified by participants of a cardiovascular rehabilitation program in a low resource context in Brazil

OBJECTIVES

Nutritional recommendations, a core component of cardiovascular rehabilitation, play a vital role in managing cardiovascular diseases. However, adherence to these recommendations is complex, particularly in low-resource settings. This study explored the barriers and facilitators influencing adherence to nutritional recommendations among participants in a low-resource cardiovascular rehabilitation program in Brazil.

METHODS

A mixed-methods approach was employed. Sociodemographic data, the Mediterranean diet score, scale for assessing nutrition, and open-ended questions on adherence were collected. Those who completed the questionnaires (phase 1) were invited to participate in one focus group session (phase 2). The participants were characterized according to the responses provided in phase 1 (Mediterranean diet score and scale for assessing nutrition) in low adherence or high adherence to dietary practice. Descriptive statistics and thematic content analysis within the context of the theory of planned behavior were employed.

RESULTS

Seventy-four participants completed phase 1, with 41.9% classified into low adherence and 27.0% in high adherence; of those, 17 participated in phase 2. Focus group findings revealed 9 themes/29 subthemes. Barriers included food prices, income, knowledge, routine, food access, family patterns, disease, work, anxiety, eating habits, and food planning. Facilitators included affordable food, health considerations, taste preferences, knowledge, family/professional support, government assistance, personal willpower, income stability, easy food access, media influence, and a quiet eating place.

CONCLUSIONS

The study findings underscore the need for targeted interventions, including individualized meal planning, community engagement, and enhanced access to healthcare professionals, to optimize dietary adherence and improve cardiovascular outcomes.

Comparing the effect of the Model of Therapeutic Engagement in cardiac rehabilitation on the sense of coherence and adherence to treatment: a randomized clinical trial

PURPOSE

The study aimed to compare the effectiveness of a traditional cardiac rehabilitation (CR) program with an enhanced program incorporating the model of therapeutic engagement (MTE) and extended remote support for patients undergoing coronary artery bypass graft (CABG) patients.

MATERIALS AND METHODS

In a randomized controlled trial, 88 CABG patients were assigned to experimental and control groups. The experimental group received integrated MTE cardiac rehabilitation, and assessments were conducted at three time points: pre-CR, one month later, and three months post-CR. The study measured medication adherence (MARS-5) and sense of coherence (SoC-13) scales.

RESULTS

The study found no significant differences in demographic factors between the experimental and control groups. However, significant differences were observed in MARS and individuals' SoC scores over time in the experimental group, with notable improvements (p < 0.001). The control group showed significant changes only up to one month. Group effects were evident, with consistent increases in the experimental group's outcomes at each assessment point.

CONCLUSION

Integrating the MTE into CR programs offers benefits in terms of medication adherence and individuals' sense of coherence, which warrants further investigation and clinical implementation.

Barriers and facilitators for increased accessibility to quality rehabilitation services in low- and middle- income countries: a systematic review

INTRODUCTION

With an increasing number of people experiencing limitations in functioning during their life course, the need for comprehensive rehabilitation services is high. In 2017, the WHO Rehabilitation 2030 initiative noted that the need for the establishment and expansion of rehabilitation services is paramount in order to obtain well-being for the population and to ensure equal access to quality healthcare for all. The organization of rehabilitation services is however facing challenges especially in low-and middle-income countries with a very small proportion of people who require rehabilitation actually getting them. Various surveys conducted in low-and -middle income countries have revealed existing gaps between the need for rehabilitation services and the actual receipt of these services. This systematic review aimed to determine the barriers and facilitators for increasing accessibility to rehabilitation services in low- and middle-income countries. Recommendations for strengthening rehabilitation service organization are presented based on the available retrieved data.

EVIDENCE ACQUISITION

In this systematic review, an electronic search through three primary databases, including Medline (PubMed), Scopus and Web of Science (WOS) was conducted to identify original studies reporting on barriers and facilitators for rehabilitation service organization in low-and middle-income countries. Date of search: 25th April 2021 (PubMed), 3rd May 2021 (Scopus and Web of Science). All studies including barriers or/and facilitators for rehabilitation services in low- and middle income countries which were written in English were included in the review. The articles written in other languages and grey literature, were excluded from this review.

EVIDENCE SYNTHESIS

Total of 42 articles were included from year 1989 to 2021. Numerous barriers were identified that related to education, resources, leadership, policy, technology and advanced treatment, community-based rehabilitation (CBR), social support, cultural influences, political issues, registries and standards of care. National health insurance including rehabilitation and funding from government and NGOs are some of the facilitators to strengthen rehabilitation service organization. Availability of CBR programs, academic rehabilitation training programs for allied health professionals, collaboration between Ministry of Heath (MOH) and Non-governmental Organizations (NGOs) on telerehabilitation services are amongst other facilitators.

CONCLUSIONS

Recommendations for improving and expanding rehabilitation service organization include funding, training, education, and sharing of resources.

Promoting cardiac rehabilitation program quality in low-resource settings: Needs assessment and evaluation of the International Council of Cardiovascular Prevention and Rehabilitation's registry quality improvement supports

BACKGROUND

Cardiac rehabilitation (CR) registries have the potential to support quality improvement (QImp). This study investigated the QImp needs of International CR Registry-participating programs and their evaluation of its' supports.

METHODS

ICRR offers comparative outcome dashboards and QImp sessions, among other features. In this qualitative study, ICRR data stewards from the 17 active on-boarded CR programs were invited to a focus group held in November 2023 via Teams; stewards not sufficiently-proficient in English were invited to provide written input. Deductive-thematic analysis using NVIVO was undertaken by 2 researchers; member-checking ensued.

RESULTS

Nine participated, and four provided input, from eight countries. Three themes emerged; saturation was achieved. First, QImp facilitators included training, institutional requirements, dedicated staff, resources in academic centres and ICRR features. Second, QImp barriers included staffing issues, the global nature of the ICRR, and structural challenges in low-resource settings. Finally, ICRR supports for QImp included didactic webinars, hearing from other programs, 1-1 support offered and assessing minimum Certification standards.

CONCLUSION

ICRR-participating programs are satisfied with QImp supports but encounter challenges, including related to language, staffing and other resources. CR registries should be leveraged and optimized to support CR programs to assess and improve their care quality.

Barriers to Cardiac Rehabilitation among Patients Diagnosed with Cardiovascular Diseases-A Scoping Review

BACKGROUND

Cardiovascular diseases (CVDs) are a rising global burden. Preventative strategies such as cardiac rehabilitation (CR) have shown a marked reduction in disease burden. Despite this, CR is underutilized worldwide. This study aims to identify the barriers to CR among patients diagnosed with CVD.

METHODS

A scoping review of the literature was conducted following the Joanna Briggs Institute (JBI) guidelines. Four major databases, including CINAHL, PubMed, EBSCOhost, and Scopus, were used to obtain studies published between 2010 and 2023. Search terms such as "Cardiac rehab*", "Barrier*", "Cardiovascular", "Disease", and "diagnosis*" were utilized in order to obtain subject-specific studies relevant to the research question.

RESULTS

From the initial 2098 studies, only 14 were included in the final analysis, consisting of both qualitative and quantitative designs. The thematic analysis included "healthcare system-related factors", "Socioeconomic factors", and "individual characteristics". Healthcare system-related factors were mostly related to the poor availability of CR programs, lack of proper referral strategies, inadequate knowledge of CR provider and inter-provider communication issues, and lack of alternative methods of CR delivery. The socioeconomic barriers were lack of education, longer distance to CR facilities, high cost of care, unemployment, and poor income status. The identified individual characteristics were female gender, older age, and comorbidities.

CONCLUSIONS

Lack of resources, poor access, educational attainment, and high cost of care were some of the barriers to CR, particularly in low- and middle-income countries (LMICs). Health policymakers and healthcare providers should implement strategies incorporating the issues identified in this scoping review. Systematic reviews may be required to confirm these findings.

A Systematic Review of Clinical Practice Guidelines and Consensus Statements for Cardiac Rehabilitation Delivery: Consensus, Divergence, and Important Knowledge Gaps

BACKGROUND

After 2020, clinical practice recommendations have been released to inform cardiac rehabilitation (CR) programs of best practices for post-COVID programming. The objective of this systematic review was to identify and summarize recommendations from clinical practice guidelines (CPGs) and consensus statements for CR delivery postpandemic.

METHODS

Five databases (March 2020 through April 2023), grey literature and Web sites of CR international associations were searched. Inclusion criteria were local, national, and international association-endorsed CPGs, and/or position, expert, and scientific statements related to CR delivery (program models, program elements, and core components). Two researchers independently screened the citations for inclusion. The Appraisal of Guidelines for Research and Evaluation (AGREE) II was used for quality assessment. Results were analyzed in accordance with the Synthesis Without Meta-analysis (SWiM) reporting guidelines.

RESULTS

Overall, 4890 records were identified; 4 CPGs, 9 position/scientific statements, and 6 expert/Delphi consensus papers were included. All guidelines/statements included information related to program delivery models, with 95% endorsing the use of virtual, hybrid, home-based, and telerehabilitation, especially during the pandemic. Outside of the context of COVID-19, program components including referral, CR indications, CR contraindications, timing, and structure were included in the 4 CPGs and 2 of 15 statements. Recommendations related to CR core components were primarily focused on exercise, with no changes since before the pandemic except for COVID-19 considerations for safety. One guideline was specific to women, and 1 scientific statement to heart failure with preserved ejection fraction.

CONCLUSIONS

Although 19 documents were identified, CR delivery in low resource settings and for culturally and linguistically diverse populations require attention. Additionally, few recommendations on nutrition, psychosocial counselling, and patient education were reported.

Effect of exercise on functional capacity and body weight for people with hypertension, type 2 diabetes, or cardiovascular disease: a systematic review with meta-analysis and trial sequential analysis

BACKGROUND

Hypertension, type 2 diabetes, and cardiovascular disease affect the activities of daily living at varying degree. While the effects of aerobic exercise on functional capacity are well-documented, the extent of change for different types of exercise in these chronic conditions remains unexplored. Additionally, there is conflicting evidence regarding the role of exercise in reducing body weight.

METHODS

We conducted systematic review with meta-analysis and trial sequential analysis and searched various databases from inception to July 2020. We included randomised clinical trials adding any form of trialist defined exercise to usual care versus usual care in people with either hypertension, type 2 diabetes, and/or cardiovascular disease irrespective of setting, publication status, year, and language. The outcomes assessed were i) functional capacity assessed through different scales separately i.e., Maximal Oxygen Uptake (VO2max), 6-min walk test (6MWT), 10-m walk test (10MWT), and ii) body weight.

RESULTS

We included 950 studies out of which 444 trials randomising 20,098 participants reported on various functional outcomes (355 trials) and body weight (169 trials). The median follow-up was 3 months (Interquartile ranges (IQR): 2.25 to 6). Exercise added to the usual care, improved VO2max (Mean Difference (MD):2.72 ml/kg/min; 95% Confidence Interval (CI) 2.38 to 3.06; p < 0.01; I2 = 96%), 6MWT (MD: 42.5 m; 95%CI 34.95 to 50.06; p < 0.01; I2 = 96%), and 10MWT (MD: 0.06 m/s; 95%CI 0.03 to 0.10; p < 0.01; I2 = 93%). Dynamic aerobic and resistance exercise showed a consistent improvement across various functional outcomes, whereas body-mind therapies (MD: 3.23 ml/kg/min; 95%CI 1.97 to 4.49, p < 0.01) seemed especially beneficial for VO2max and inspiratory muscle training (MD: 59.32 m; 95%CI 33.84 to 84.80; p < 0.01) for 6MWT. Exercise yielded significant reduction in body weight for people with hypertension (MD: -1.45 kg; 95%CI -2.47 to -0.43; p < 0.01), and type 2 diabetes (MD: -1.53 kg; 95%CI -2.19 to -0.87; p < 0.01) but not for cardiovascular disease with most pronounced for combined exercise (MD: -1.73 kg; 95%CI -3.08 to -0.39; p < 0.05). The very low certainty of evidence warrants cautious interpretations of the results.

CONCLUSION

Exercise seemed to improve functional capacity for people with hypertension, type 2 diabetes, and/or cardiovascular disease but the effectiveness seems to vary with different forms of exercise. The potentially superior improvement in VO2max and 6MWT by body-mind therapies and inspiratory muscle training calls for further exploration. Additionally, prescribing exercise for the sole purpose of losing weight may be a potential strategy for people with hypertension and type 2 diabetes. The extent of improvement in functional capacity and body weight reduction differed with different exercise regimens hence personalised exercise prescriptions tailored to individual needs may be of importance.

Development and Evaluation of the International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) Program Certification for Low-Resource Settings

Background

Cardiac rehabilitation (CR) is a proven model of secondary prevention, but new sites, providing quality care, are needed in low-resource settings. This study (1) described the development of International Council of Cardiovascular Prevention and Rehabilitation's (ICCPR) Program Certification and (2a) tested its implementation, considering (b) appropriateness of quality standards for these settings.

Methods

The Steering Committee finalized 13 standards, requiring 70% be met. They are assessed initially through International CR Registry (ICRR) program survey and patient data; if Certification appears possible, a two-hour virtual site assessment is arranged to corroborate. Standard operating procedures for Assessor training were developed. A multi-method pilot study was then undertaken with a quantitative (description of quality indicators) and qualitative (focus groups on MS Teams) component. ICRR sites with post-program data by April 2022 were invited to participate. Two team members independently analyzed focus group transcripts, using a deductive-thematic approach with NVIVO.

Results

Five CR programs from the Eastern Mediterranean, South-East Asian and American regions participated. Upon application, with some data cleaning, initially four programs were eligible to proceed to virtual site assessment. Ultimately, all five programs were certified, each meeting a minimum of 12/13 standards (peak MET increase and program completion rate were not met by some centres). Four themes resulted from the two focus groups of 13 site data stewards: motivation and benefits (eg, international recognition, additional program resources), logistics (eg, communication, cost, site visit process), the standards and their assessment (eg, balance of rigor and feasibility), and suggestions for improvement (eg, website).

Conclusion

ICCPR's Program Certification has been demonstrated to be feasible, rigorous, and acceptable. Standards are attainable in low-resource settings. Certified programs reap benefits including additional resources. This first international Certification is suitable for low-resource settings, to complement that from the American and European CR Societies.

Evaluation of counselling materials for hybrid cardiac rehabilitation in a low-resource setting: Perceptions of patients and providers

OBJECTIVE

This study evaluated the usefulness of a booklet as support material for counseling focused on self-efficacy and therapist interaction in the course of counseling in a hybrid CR program (i.e., supervised and unsupervised sessions) developed for low-resource settings.

METHODS

Counseling material was developed by a multidisciplinary team, with patient input. Using multi-methods, first input from patients from six centers in Chile was sought through a telephone survey (cross-sectional). Second, input from physiotherapists delivering the intervention at all centres was solicited qualitatively through a focus group on Zoom. Content analysis was performed using a deductive-thematic approach.

RESULTS

Seventy-one patients were included. All (100 %) participants responded that the materials were easy to understand, contained suggestions applicable to daily life, captured their attention and was useful for future questions. The booklet overall was rated 6.7 ± 0.6/7 %, and 98.2 % were satisfied with the counselling. Overall themes from the six deliverers related to the CR intervention (e.g., well manualized protocols for counselling), the deliverer (e.g., expertise to deliver) and patients (e.g., found information useful).

CONCLUSION

The usefulness of the counseling together with the supporting booklet was established by patients and delivering professionals.

PRACTICE IMPLICATIONS

Thus, with some final refinement, this resource can be disseminated for use by other Spanish CR programs.

Risk factors in cardiovascular patients: Challenges and opportunities to improve secondary prevention

BACKGROUND

Effective management of major cardiovascular risk factors is of great importance to reduce mortality from cardiovascular disease (CVD). The Survey of Risk Factors in Coronary Heart Disease (SURF CHD) II study is a clinical audit of the recording and management of CHD risk factors. It was developed in collaboration with the European Association of Preventive Cardiology and the European Society of Cardiology (ESC). Previous studies have shown that control of major cardiovascular risk factors in patients with established atherosclerotic CVD is generally inadequate. Azerbaijan is a country in the South Caucasus, a region at a very high risk for CVD.

AIM

To assess adherence to ESC recommendations for secondary prevention of CVD based on the measurement of both modifiable major risk factors and their therapeutic management in patients with confirmed CHD at different hospitals in Baku (Azerbaijan).

METHODS

Six tertiary health care centers participated in the SURF CHD II study between 2019 and 2021. Information on demographics, risk factors, physical and laboratory data, and medications was collected using a standard questionnaire in consecutive patients aged ≥ 18 years with established CHD during outpatient visits. Data from 687 patients (mean age 59.6 ± 9.58 years; 24.9% female) were included in the study.

RESULTS

Only 15.1% of participants were involved in cardiac rehabilitation programs. The rate of uncontrolled risk factors was high: Systolic blood pressure (BP) (SBP) (54.6%), low-density lipoprotein cholesterol (LDL-C) (86.8%), diabetes mellitus (DM) (60.6%), as well as overweight (66.6%) and obesity (25%). In addition, significant differences in the prevalence and control of some risk factors [smoking, body mass index (BMI), waist circumference, blood glucose (BG), and SBP] between female and male participants were found. The cardiovascular health index score (CHIS) was calculated from the six risk factors: Non- or ex-smoker, BMI < 25 kg/m2, moderate/vigorous physical activity, controlled BP (< 140/90 mmHg; 140/80 mmHg for patients with DM), controlled LDL-C (< 70 mg/dL), and controlled BG (glycohemoglobin < 7% or BG < 126 mg/dL). Good, intermediate, and poor categories of CHIS were identified in 6%, 58.3%, and 35.7% of patients, respectively (without statistical differences between female and male patients).

CONCLUSION

Implementation of the current ESC recommendations for CHD secondary prevention and, in particular, the control rate of BP, are insufficient. Given the fact that patients with different comorbid pathologies are at a very high risk, this is of great importance in the management of such patients. This should be taken into account by healthcare organizers when planning secondary prevention activities and public health protection measures, especially in the regions at a high risk for CVD. A wide range of educational products based on the Clinical Practice Guidelines should be used to improve the adherence of healthcare professionals and patients to the management of CVD risk factors.

Global perspectives on heart disease rehabilitation and secondary prevention: a scientific statement from the Association of Cardiovascular Nursing and Allied Professions, European Association of Preventive Cardiology, and International Council of Cardiovascular Prevention and Rehabilitation

Cardiovascular disease is a leading cause of death, morbidity, disability, and reduced health-related quality of life, as well as economic burden worldwide, with some 80% of disease burden occurring in the low- and middle-income country (LMIC) settings. With increasing numbers of people living longer with symptomatic disease, the effectiveness and accessibility of secondary preventative and rehabilitative health services have never been more important. Whilst LMICs experience the highest prevalence and mortality rates, the global approach to secondary prevention and cardiac rehabilitation, which mitigates this burden, has traditionally been driven from clinical guidelines emanating from high-income settings. This state-of-the art review provides a contemporary global perspective on cardiac rehabilitation and secondary prevention, contrasting the challenges of and opportunities for high vs. lower income settings. Actionable solutions to overcome system, clinician, programme, and patient level barriers to cardiac rehabilitation access in LMICs are provided.

Pilot testing of the International Council of Cardiovascular Prevention and Rehabilitation Registry

The International Council of Cardiovascular Prevention and Rehabilitation developed an International Cardiac Rehabilitation (CR) Registry (ICRR) to support CR programs in low-resource settings to optimize care provision and patient outcomes. This study assessed implementation of the ICRR, site data steward experience with on-boarding and data entry, and patient acceptability. Multimethod observational pilot involves (I) analysis of ICRR data from three centers (Iran, Pakistan, and Qatar) from inception to May 2022, (II) focus group with on-boarded site data stewards (also from Mexico and India), and (III) semistructured interviews with participating patients. Five hundred sixty-seven patients were entered. Based on volumes at each program, 85.6% of patients were entered in ICRR. 99.3% patients approached consented to participate. The average time to enter data at pre- and follow-up assessments by source was 6.8-12.6 min. Of 22 variables preprogram, completion was 89.5%. Among patients with any follow-up data, of four program-reported variables, completion was 99.0% in program completers and 51.5% in none; of 10 patient-reported variables, completion was 97.0% in program completers and 84.8% in none. The proportion of patients with any follow-up data was 84.8% in program completers, with 43.6% of noncompleters having any data entered other than completion status. Twelve data stewards participated in the focus group. Main themes were valuable on-boarding process, data entry, process of engaging patients, and benefits of participation. Thirteen patients were interviewed. Themes were good understanding of the registry, positive experience providing data, and value of lay summary and eagerness for annual assessment. Feasibility and data quality of ICRR were demonstrated.

Unmet Needs for Cardiac Rehabilitation in Africa: A Perennial Gap in the Management of Individuals with Cardiac Diseases

Cardiac rehabilitation (CR) is a standard model of care, and an established component of comprehensive care that has been proven to reduce mortality and morbidity in patients with cardiac diseases. International clinical practice guidelines routinely recommend that cardiac patients participate in CR programs for comprehensive secondary prevention. However, there is scant guidance on how to deliver these programs in low-resourced settings. This dearth of clinical practice guidelines may be an indication of low emphasis placed on CR as a component of cardiac health services in low-income countries, especially in Africa. Indeed, CR programs are almost non-existent in Africa despite the unmet need for CR in patients with ischemic heart disease in Africa reported to be about one million. This figure represents the highest unmet need of any World Health Organization region, and is colossal given the projected accelerated increases in incidence of cardiovascular diseases (CVD) in the region. This narrative review explored the availability of CR programs, potential barriers to CR and strategies that can mitigate such barriers in Africa.

Cardiac rehabilitation for heart failure: 'Cinderella' or evidence-based pillar of care?

Cardiac rehabilitation remains the 'Cinderella' of treatments for heart failure. This state-of-the-art review provides a contemporary update on the evidence base, clinical guidance, and status of cardiac rehabilitation delivery for patients with heart failure. Given that cardiac rehabilitation participation results in important improvements in patient outcomes, including health-related quality of life, this review argues that an exercise-based rehabilitation is a key pillar of heart failure management alongside drug and medical device provision. To drive future improvements in access and uptake, health services should offer heart failure patients a choice of evidence-based modes of rehabilitation delivery, including home, supported by digital technology, alongside traditional centre-based programmes (or combinations of modes, 'hybrid') and according to stage of disease and patient preference.

Technology-based Comprehensive Cardiac Rehabilitation Therapy (TaCT) for women with cardiovascular disease in a middle-income setting: A randomized controlled trial protocol

Women are underrepresented in cardiac rehabilitation (CR) despite the benefits, and this is exacerbated in lower-resource settings where CR is insufficiently available. In this randomized controlled trial, the effectiveness of the Technology-based Comprehensive Cardiac Rehabilitation Therapy (TaCT) electronic cardiac rehabilitation (eCR) intervention on functional capacity, risk factors, quality of life, heart-health behaviors, symptoms, and morbidity will be tested among women with CVD in a middle-income country. Following a pilot study, a single-center, single-blinded, 2 parallel-arm (1:1 SNOSE) superiority trial comparing an eCR intervention (TaCT) to usual care, with assessments pre-intervention and at 3 and 6 months will be undertaken. One hundred adult women will be recruited. Permuted block (size 10) randomization will be applied. The 6-month intervention comprises an app, website, SMS texts with generic heart-health management advice, and bi-weekly 1:1 telephone calls with a nurse trainee. Individualized exercise prescriptions will be developed based on an Incremental Shuttle Walk Test (primary outcome) and dietary plans based on 24 h dietary recall. A yoga/relaxation video will be provided via WhatsApp, along with tobacco cessation support and a moderated group chat. At 3 months, intervention engagement and acceptability will be assessed. Analyses will be conducted based on intent-to-treat. If results of this novel trial of women-focused eCR in a middle-income country demonstrate clinically-significant increases in functional capacity, this could represent an important development for the field considering this would be an important outcome for women and would translate to lower mortality.

Qualitative study measuring the usability of the International Cardiac Rehabilitation Registry

OBJECTIVE

Cardiac rehabilitation (CR) is a comprehensive model of secondary preventive care. There is a wide variety in implementation characteristics globally, and hence quality control is paramount. Thus, the International Council of Cardiovascular Prevention and Rehabilitation was urged to develop a CR registry. The purpose of this study was to test the perceived usability of the International Cardiac Rehabilitation Registry (ICRR) to optimise it.

DESIGN

This was a qualitative study, comprising virtual usability tests using a think-aloud method to elicit feedback on the ICRR, while end-users were entering patient data, followed by semistructured interviews.

SETTING

Ultimately, 12 tests were conducted with CR staff (67% female) in low-resource settings from a variety of disciplines in all regions of the world but Europe before saturation was achieved.

PRIMARY OUTCOME MEASURE

Participants completed the System Usability Scale. Interviews were transcribed verbatim except to preserve anonymity, and coded using NVIVO by two researchers independently. The Unified Theory of Acceptance and Use of Technology 2 informed analysis.

RESULTS

The ICRR was established as easy to use, relevant, efficient, with easy learnability, operability, perceived usefulness, positive perceptions of output quality and high end-user satisfaction. System usability was 83.75, or 'excellent' and rated 'A'. Four major themes were deduced from the interviews: (1) ease of approvals, adoption and implementation; (2) benefits for programmes, (3) variables and their definitions, as well as (4) patient report and follow-up assessment. Based on participant observation and utterances, suggestions for changes to the ICRR were implemented, including to the programme survey, on-boarding processes, navigational instructions, inclusion of programme logos, direction on handling unavailable data and optimising data completeness, as well as policies for authorship and programme certification.

CONCLUSIONS

With usability of the ICRR optimised, pilot testing shall ensue.

Cardiac telerehabilitation in a middle-income country: analysis of adherence, effectiveness and cost through a randomized clinical trial

BACKGROUND

The benefits of cardiac rehabilitation (CR) are already well established; however, such intervention has been underused, mainly in low- and middle-income countries.

AIM

To compare adherence, effectiveness, and cost of a home CR with the traditional CR (TCR) in a middle-income country (MIC).

DESIGN

Single-blind randomized control trial.

SETTING

A university hospital.

POPULATION

Individuals with coronary disease that were eligible were invited to participate. A randomized sample of 51 individuals was selected, where two participants were not included by not meeting inclusion criteria.

METHODS

The home-CR group participated in health education activities, carried out two supervised exercise sessions, and was instructed to carry out 58 sessions at home. Weekly telephone calls were made. The TCR group held 24 supervised exercise sessions and were instructed to carry out 36 sessions at home.

RESULTS

49 individuals (42 male, 56.37±10.35years) participated in the study, 23 in the home-CR group and 26 in the TCR group. After the intervention, adherence in the home-CR and TCR groups was 94.18% and 79.08%, respectively, with no significant difference (P=0.191). Both protocols were effective for the other variables, with no differences. The cost per patient for the service was lower in the home-CR (US$ 59.31) than in the TCR group (US$ 135.05).

CONCLUSIONS

CR performed at home in an MIC demonstrated similar adherence and effectiveness compared to the TCR program, but with a lower cost for the service. The results corroborate the possibility of using home CR programs, even in MICs, after exercise risk stratification and under remote supervision.

CLINICAL REHABILITATION IMPACT

Home-CR can contribute to overcome participants' barriers with compatible cost. Home-CR is effective in improving functional capacity and risk factors control. Perform risk stratification and remote supervision are essential to offer Home-CR.

Trends in cardiac rehabilitation enrollment post-coronary artery bypass grafting upon implementation of automatic referral in Southeast Asia: A retrospective cohort study

Introduction: Cardiac rehabilitation (CR) is an effective but underutilized intervention. Strategies have been identified to increase its use, but there is paucity of data testing them in low-resource settings. We sought to determine the effect of automatic referral post-coronary artery bypass graft (CABG) surgery on CR enrollment.

Methods: This is a retrospective cohort study assessing cardiac patients referred to CR at a tertiary center in Southeast Asia from 2013 to 2019. The paper-based pathway was introduced at the end of 2012. The checklist with automatic CR referral on the third day post-operation prompted a nurse to educate the patient about CR, initiate phase 1 and encourage enrollment in phase 2. Patients who were not eligible for the pathway for administrative or clinical reasons were referred at the discretion of the attending physician (i.e., usual care). Enrollment was defined as attendance at≥1 CR visit.

Results: Of 4792 patients referred during the study period, 394 enrolled in CR. Significantly more patients referred automatically enrolled compared to usual care (225 [11.8%] vs. 169 [5.8%]; OR=2.2, 95% CI=1.8-2.7), with increases up to 23.4% enrollment in 2014 (vs. average enrollment rate of 5.9% under usual referral). Patients who enrolled following automatic referral were significantly younger and more often employed (both P<0.001); no other differences were observed.

Conclusion: In a lower-resource, Southeast Asian setting, automatic CR referral is associated with over two times greater enrollment in phase 2 CR, although efforts to maintain this effect are required.

Building Capacity Through ICCPR Cardiovascular Rehabilitation Foundations Certification (CRFC): EVALUATION OF REACH, BARRIERS, AND IMPACT

PURPOSE

The International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) developed an online Cardiovascular Rehabilitation Foundations Certification (CRFC; https://globalcardiacrehab.com/Certification) in October 2017, to build cardiac rehabilitation (CR) delivery capacity in low-resource settings based on their guidelines. Herein we evaluate its reach globally, barriers to its completion, as well as satisfaction and impact of the course among those completing it.

METHODS

The country of origin of all applicants was tallied. An online survey was developed for learners who completed the CRFC (completers), and for those who applied but did not yet complete the program (noncompleters), administered using Google Forms.

RESULTS

With regard to reach, 236 applications were received from 23/203 (11%) countries in the world; 51 (22%) were from low- or middle-income countries. A total of 130 (55%) have completed the CRFC; mean scores on the final examination were 88.3 ± 7.1%, with no difference by country income classification (P= .052). Sixteen (22%) noncompleters and 37 (34%) completers responded to the survey. Barriers reported by noncompleters were time constraints, cost, and technical issues. Overall satisfaction (scale 1-5) with the CRFC was high (4.49 ± 0.51); most completers would highly recommend the CRFC to others (4.30 ± 0.66), and perceived that the information provided will contribute to their work and/or the care of their patients (4.38 ± 0.89); 29 (78%) had used the information from the CRFC in their practice.

CONCLUSIONS

The reach of the CRFC still needs to be broadened, in particular in low-resource settings. Learners are highly satisfied with the certification, and its impacts on CR practice are encouraging. Input has been implemented to improve the CRFC.

[The importance of cardiorehabilitation in the era of modern treatment of cardio-vascular diseases]

Cardiac rehabilitation (CR) has a class IA indication in international and national guidelines as an intervention with proven efficacy for decreasing cardiovascular and all-cause mortality in various categories of cardiological patients. However, CR is one of the least used current technologies for the treatment of patients with cardiovascular diseases worldwide. This article presents the state of the CR problem during the epoch of high-tech treatments of cardiovascular diseases; the prevalence of using CR in various countries; traditional and new methodological approaches, including telemedicine; and clinical and prognostic effects of CR in various categories of patients with cardiovascular diseases.

The role of cardiac rehabilitation in improving cardiovascular outcomes

Cardiac rehabilitation is a complex intervention that seeks to improve the functional capacity, wellbeing and health-related quality of life of patients with heart disease. A substantive evidence base supports cardiac rehabilitation as a clinically effective and cost-effective intervention for patients with acute coronary syndrome or heart failure with reduced ejection fraction and after coronary revascularization. In this Review, we discuss the major contemporary challenges that face cardiac rehabilitation. Despite the strong recommendation in current clinical guidelines for the referral of these patient groups, global access to cardiac rehabilitation remains poor. The COVID-19 pandemic has contributed to a further reduction in access to cardiac rehabilitation. An increasing body of evidence supports home-based and technology-based models of cardiac rehabilitation as alternatives or adjuncts to traditional centre-based programmes, especially in low-income and middle-income countries, in which cardiac rehabilitation services are scarce, and scalable and affordable models are much needed. Future approaches to the delivery of cardiac rehabilitation need to align with the growing multimorbidity of an ageing population and cater to the needs of the increasing numbers of patients with cardiac disease who present with two or more chronic diseases. Future research priorities include strengthening the evidence base for cardiac rehabilitation in other indications, including heart failure with preserved ejection fraction, atrial fibrillation and congenital heart disease and after valve surgery or heart transplantation, and evaluation of the implementation of sustainable and affordable models of delivery that can improve access to cardiac rehabilitation in all income settings.

Knowledge, attitudes, and practices of cardiopulmonary rehabilitation among physiotherapists in Lebanon

Background

Insufficient physical activity is one of the leading mortality risks worldwide for cardiovascular and pulmonary diseases. Physiotherapists (PT) are core healthcare professionals who play a major role in the prevention of disease complications and in inspiring a healthy lifestyle. To identify challenges in the promotion of cardiopulmonary rehabilitation (CR) in Lebanon, a survey was conducted among PT and physiotherapy students. The aim was to assess the knowledge, attitudes, and practices of CR in Lebanon.

Results

The response rate was 46.1% (N = 322). Results show that 24.5% of respondents have good to excellent knowledge about CR. More than 60% of the respondents indicate possible barriers to starting a CR program, and one of two respondents identify the absence of skills as a main barrier. Findings highlight the importance of the role of PT as a mediator to increase a healthy lifestyle among patients and to promote the prevention of cardiovascular diseases and pulmonary diseases in the country.

Conclusions and recommendations

Our results support the evidence and clinical guidelines that PT play a major role by increasing the participation of patients in CR. A cost-effective CR program needs to be covered by the private and public system in Lebanon.

Effects of cardiac rehabilitation in low-and middle-income countries: A systematic review and meta-analysis of randomised controlled trials

OBJECTIVES

To assess the effectiveness of cardiac rehabilitation (CR) in low- and middle-income countries (LMICs), given previous reviews have included scant trials from these settings and the great need there.

METHODS

Six electronic databases (PubMed, Medline, Embase, CINAHL, Cochrane Library, and APA PsycINFO) were searched from inception-May 2020. Randomised controlled CR (i.e., at least initial assessment and structured exercise; any setting; some Phase II) trials with any clinical outcomes (e.g., mortality and morbidity, functional capacity, risk factor control and psychosocial well-being) or cost, with usual care (UC) control or active comparison (AC), in acute coronary syndrome with or without revascularization or heart failure patients in LMICs were included. With regard to data extraction and data synthesis, two reviewers independently vetted identified citations and extracted data from included trials; Risk of bias was assessed using Cochrane's tool. Certainty of evidence was ascertained based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. A random-effects model was used to calculate weighted mean differences and 95% confidence intervals (CI).

RESULTS

Twenty-six trials (6380 participants; 16.9% female; median follow-up = 3 months) were included. CR meaningfully improved functional capacity (VO2peak vs UC: 5 trials; mean difference [MD] = 3.13 ml/kg/min, 95% CI = 2.61 to 3.65; I2 = 9.0%); moderate-quality evidence), systolic blood pressure (vs UC: MD = -5.29 mmHg, 95% CI = -8.12 to -2.46; I2 = 45%; low-quality evidence), low-density lipoprotein cholesterol (vs UC: MD = -16.55 mg/dl, 95% CI = -29.97 to -3.14; I2 = 74%; very low-quality evidence), body mass index (vs AC: MD = -0.84 kg/m2, 95% CI = -1.61 to -0.07; moderate-quality evidence; I2 = 0%), and quality of life (QoL; vs UC; SF-12/36 physical: MD = 6.05, 95% CI = 1.77 to 10.34; I2 = 93%, low-quality evidence; mental: MD = 5.38, 95% CI = 1.13 to 9.63; I2 = 84%; low-quality evidence), among others. There were no evidence of effects on mortality or morbidity. Qualitative analyses revealed CR was associated with lower percutaneous coronary intervention, myocardial infarction, better cardiovascular function, and biomarkers, as well as return to life roles; there were other non-significant effects. Two studies reported low cost of home-based CR.

CONCLUSIONS

Low to moderate-certainty evidence establishes CR as delivered in LMICs improves functional capacity, risk factor control and QoL. While more high-quality research is needed, we must augment access to CR in these settings.

Current status of cardiac rehabilitation among representative hospitals treating acute myocardial infarction in South Korea

Cardiac rehabilitation services are mostly underutilized despite the documentation of substantial morbidity and mortality benefits of cardiac rehabilitation post-acute myocardial infarction. To assess the implementation rate and barriers to cardiac rehabilitation in hospitals dealing with acute myocardial infarction in South Korea, between May and July 2016, questionnaires were emailed to cardiology directors of 93 hospitals in South Korea; all hospitals were certified institutes for coronary interventions. The questionnaires included 16 questions on the hospital type, cardiology practice, and implementation of cardiac rehabilitation. The obtained data were categorized into two groups based on the type of the hospital (secondary or tertiary) and statistically analysed. Of the 72 hospitals that responded (response rate of 77%), 39 (54%) were tertiary medical centers and 33 (46%) were secondary medical centers. All hospitals treated acute myocardial infarction patients and performed emergency percutaneous coronary intervention; 79% (57/72) of the hospitals performed coronary artery bypass grafting. However, the rate of implementation of cardiac rehabilitation was low overall (28%, 20/72 hospitals) and even lower in secondary medical centers (12%, 4/33 hospitals) than in tertiary centers (41%, 16/39 hospitals, p = 0.002). The major barriers to cardiac rehabilitation included the lack of staff (59%) and lack of space (33%). In contrast to the wide availability of acute-phase invasive treatment for AMI, the overall implementation of cardiac rehabilitation is extremely poor in South Korea. Considering the established benefits of cardiac rehabilitation in patients with acute myocardial infarction, more administrative support, such as increasing the fee for cardiac rehabilitation services by an appropriate level of health insurance coverage should be warranted.

Developing a Complex Understanding of Physical Activity in Cardiometabolic Disease from Low-to-Middle-Income Countries-A Qualitative Systematic Review with Meta-Synthesis

Physical activity behaviour is complex, particularly in low-resource settings, while existing behavioural models of physical activity behaviour are often linear and deterministic. The objective of this review was to (i) synthesise the wide scope of factors that affect physical activity and thereby (ii) underpin the complexity of physical activity in low-resource settings through a qualitative meta-synthesis of studies conducted among patients with cardiometabolic disease living in low-to-middle income countries (LMIC). A total of 41 studies were included from 1200 unique citations (up to 15 March 2021). Using a hybrid form of content analysis, unique factors (n = 208) that inform physical activity were identified, and, through qualitative meta-synthesis, these codes were aggregated into categories (n = 61) and synthesised findings (n = 26). An additional five findings were added through deliberation within the review team. Collectively, the 31 synthesised findings highlight the complexity of physical activity behaviour, and the connectedness between person, social context, healthcare system, and built and natural environment. Existing behavioural and ecological models are inadequate in fully understanding physical activity participation in patients with cardiometabolic disease living in LMIC. Future research, building on complexity science and systems thinking, is needed to identify key mechanisms of action applicable to the local context.

Exploration of current challenges in rehabilitation from the perspective of healthcare professionals: Switzerland as a case in point

Rehabilitation is a health strategy with the potential to mitigate the negative health consequences of population ageing and the rise of noncommunicable diseases. Literature indicates that even in high-income countries rehabilitation services can be improved. The purpose of this study is to engage rehabilitation professionals in Switzerland in identifying and prioritizing current challenges in the development and delivery of rehabilitation services. We conducted a qualitative study consisting of interviews with key informants and a stakeholder consultation. Thirteen interviews were conducted and analysed using inductive thematic analysis. Identified challenges were refined, extended, and prioritized through multi-voting in a workshop attended by a wide range of rehabilitation professional organizations. Final results were subject to further analysis and member checking. We identified nineteen challenges, of which eight were viewed as highly important. Results suggest the need to revise the financing system for rehabilitation services, highlighted a poor integration of rehabilitation in primary care, a lack of academic rehabilitation training, and insufficient funding for research. Finally, we identified a perceived lack of awareness for rehabilitation among policy-makers and the public. This study provides a unique perspective on challenges in rehabilitation practice and policy and offers an opportunity for professionals, policy-makers, and other stakeholders, to influence and guide the rehabilitation service agenda both in Switzerland and in terms of mutual learning also in other countries.

Cardiac Rehabilitation: Under-Utilized Globally

PURPOSE OF REVIEW

Cardiac rehabilitation (CR) is grossly under-utilized. This review summarizes current knowledge about degree of CR utilization, reasons for under-utilization, and strategies to increase use.

RECENT FINDINGS

ICCPR's global CR audit quantified for the first time the number of additional CR spots needed per year to treat indicated patients, so there are programs they may use. The first randomized trial of automatic/systematic CR referral has shown it results in significantly greater patient completion. Moreover, the recent update of the Cochrane review on interventions to increase use has provided unequivocal evidence on the significant impact of clinician CR encouragement at the bedside; a course is now available to train clinicians. The USA is leading the way in implementing automatic referral with inpatient-clinician CR discussions. Suggestions to triage patients based on risk to less resource-intensive, unsupervised program models could simultaneously expand capacity and support patient adherence.

Traditional versus extended hybrid cardiac rehabilitation based on the continuous care model for coronary artery bypass surgery patients in a middle-income country: A Randomized Clinical Trial

OBJECTIVE

To compare traditional (1-month supervised) versus hybrid cardiac rehabilitation (CR; usual care) with an additional 3 months offered remotely based on the continuous care model (CCM; intervention), in coronary artery bypass graft (CABG) patients.

DESIGN

randomized controlled trial, with blinded outcome assessment.

SETTING

A major heart center in a middle-income country.

PARTICIPANTS

Of 107 eligible patients that were referred to CR during the period of study, 88 (82.2%) were enrolled (target sample size). Participants were randomly assigned 1:1 (concealed; 44 per parallel arm). There was 92.0% retention.

INTERVENTION

After CR, participants were given an app and communicated biweekly with the nurse from months 1-4 to control risk factors.

MAIN OUTCOME MEASURES

Quality of life (QoL; SF-36; primary outcome), functional capacity (treadmill test), depression, anxiety and stress (DASS-21) were evaluated pre-CR, after one month, and three months after CR (end of intervention), as well as re-hospitalization.

RESULTS

The analysis of variance interaction effects for the physical and mental component summary scores of QoL were <.001, favoring intervention (per protocol); there were also significant increases from pre-CR to 1 month, and from 1 month to the final assessment in the intervention arm (p-values<.001), with change in the control arm only to 1 month. The effect sizes were 0.115 and 0.248, respectively. Similarly, the interaction effect for functional capacity was significant (p<.001), with a clinically-significant 1.5 MET increase in the intervention arm. There were trends for group effects for the psychosocial indicators, with paired t-tests revealing significant increases in each at both assessment points in the intervention arm. At 4 months, there were 4 (10.3%) re-hospitalizations in the control arm, and none in intervention (p=.049). Intended theoretical mechanisms were also impacted by the intervention.

CONCLUSION

Extending CR in this accessible manner, rendering it more comprehensive, was effective in improving outcomes.

Unravelling 'low-resource settings': a systematic scoping review with qualitative content analysis

INTRODUCTION

The effects of healthcare-related inequalities are most evident in low-resource settings. Such settings are often not explicitly defined, and umbrella terms which are easier to operationalise, such as 'low-to-middle-income countries' or 'developing countries', are often used. Without a deeper understanding of context, such proxies are pregnant with assumptions, insinuate homogeneity that is unsupported and hamper knowledge translation between settings.

METHODS

A systematic scoping review was undertaken to start unravelling the term 'low-resource setting'. PubMed, Africa-Wide, Web of Science and Scopus were searched (24 June 2019), dating back ≤5 years, using terms related to 'low-resource setting' and 'rehabilitation'. Rehabilitation was chosen as a methodological vehicle due to its holistic nature (eg, multidisciplinary, relevance across burden of disease, and throughout continuum of care) and expertise within the research team. Qualitative content analysis through an inductive approach was used.

RESULTS

A total of 410 codes were derived from 48 unique articles within the field of rehabilitation, grouped into 63 content categories, and identified nine major themes relating to the term 'low-resource setting'. Themes that emerged relate to (1) financial pressure, (2) suboptimal healthcare service delivery, (3) underdeveloped infrastructure, (4) paucity of knowledge, (5) research challenges and considerations, (6) restricted social resources, (7) geographical and environmental factors, (8) human resource limitations and (9) the influence of beliefs and practices.

CONCLUSION

The emerging themes may assist with (1) the groundwork needed to unravel 'low-resource settings' in health-related research, (2) moving away from assumptive umbrella terms like 'low-to-middle-income countries' or 'low/middle-income countries' and (3) promoting effective knowledge transfer between settings.

Translation and evaluation of a comprehensive educational program for cardiac rehabilitation patients in Latin America: A multi-national, longitudinal study

OBJECTIVES

To translate, cross-culturally adapt and validate a comprehensive evidence- and theoretically-based CR education intervention in Latin America.

METHODS

First, best practices in translation and cross-cultural adaptation were applied through 6 steps. Then, the Spanish version was delivered to CR participants from programs in Colombia, Costa Rica and Peru for validation, such that the evaluation was pre-post, uncontrolled, pragmatic, observational, and prospective in design. Participants completed surveys assessing knowledge, health literacy, self-efficacy, and health behaviours. All outcomes were assessed pre-, and post-CR, as well as 6 months after CR completion.

RESULTS

After translation of the patient guide from English to Spanish, 5 of the 9 booklets were culturally adapted. Two-hundred and forty-nine patients consented to participate, of which 184 (74 %) completed post-CR, and 121 (48 %) completed final assessments. There was a significant improvement in disease-related knowledge pre- to post-CR, as well as in health literacy, self-efficacy, and health behaviours (all p < 0.05). These gains were sustained 6 months post-program. With adjustment, CR attendance (i.e., exposure to the education) was associated with greater post-CR knowledge (ß = 0.026; p = 0.01).

CONCLUSION

A patient education intervention for CR patients in Latin America has been validated, and wider implementation is warranted.

PRACTICE IMPLICATIONS

Application of this first-ever validated CR education program for Spanish-speaking settings may result in secondary prevention.

Harnessing artificial intelligence in cardiac rehabilitation, a systematic review

Aim: This systematic review aims to evaluate the current body of research surrounding the efficacy of artificial intelligence (AI) in cardiac rehabilitation. Presently, AI can be incorporated into personal devices such as smart watches and smartphones, in diagnostic and home monitoring devices, as well as in certain inpatient care settings. Materials & methods: The PRISMA guidelines were followed in this review. Inclusion and exclusion criteria were set using the Population, Intervention, Comparison and Outcomes (PICO) tool. Results: Eight studies meeting the inclusion criteria were found. Conclusion: Incorporation of AI into healthcare, cardiac rehabilitation delivery, and monitoring holds great potential for early detection of cardiac events, allowing for home-based monitoring, and improved clinician decision making.
